Glass industry: benefit first, who pays for polluting the black hole

pm2.5, the key words such as haze, environmental protection and air pollution control have long been known to us. In the eyes of many people, they may not be unfamiliar with the environmental pollution caused by cement, steel, thermal power, chemical industry, metal smelting, electroplating and other industries, but they know little about the adverse effects of glass that appears in our lives every day

not long ago, the national development and Reform Commission and the Ministry of industry and information technology held a video conference on the implementation of the guiding opinions of the State Council on resolving the contradiction of serious overcapacity. In the video conference, the two ministries and commissions proposed that it is strictly prohibited to increase projects in industries with overcapacity and focus on resolving the contradiction of overcapacity. And flat glass has appeared in these projects. Recently, securities has visited relevant glass manufacturers in Shahe City, Hebei Province and Guangdong Province, which is known as China's Glass City, and indeed found a lot of information about the pollution problems and production capacity of the glass industry

Shahe, the city of glass: the situation of air pollution is not optimistic

walking in the jinbaijia Industrial Zone, Shahe City, Hebei Province, there are endless large trucks passing by. As long as you pay a little attention, these passing trucks are carrying three kinds of goods: coal, sand and glass. This industrial area is only 10 kilometers away from Shahe downtown. There are several small villages nearby. This is indeed a Chinese Glass City accounting for 15% of the total glass output in China. Every few steps along the main road, you will find signs of various glass manufacturers or glass dealers. These plants and stores are either on the main road or extend to some alleys

the dust is flying, there are many chimneys of all sizes, the pungent smell of coal burning, and the road is full of fragmented sand and cinders. This is the leading feeling of the golden Baijia Industrial Zone in Shahe City. According to the conversation with nearby residents, the large and small glass factories here use coal as the main fuel for glass production. This can be proved by the pungent smell of burning coal along the way in the industrial zone

"From the name Shahe, we can know that there are abundant mineral resources here, which exactly meet the various needs of glass production. There are various large and small glass factories here, including great wall glass, safety glass company, Yuanhua glass, Xinli glass, etc. in fact, when these glass factories were not fully built, the environment in our villages was very good, but now the environment is much worse Once upon a time. In a twinkling of an eye, these large and small glass factories have been built for more than ten years. " The local villagers said to

he also revealed that, "We often see that their chimneys emit some yellow or gray smoke. In fact, when we see these smoke, we know that these factories have not turned on the corresponding environmental protection devices; if there is an inspection, small factories will stop working, and large factories will turn on some environmental protection devices, so the smoke will be white. However, there is still a strong pungent smell of coal burning, and many factories will start at night Then the waste gas will be discharged directly without being treated by environmental protection devices. "

according to the relevant report on air quality in the third quarter of this year released by the Ministry of environmental protection, Hebei accounted for seven of the top ten cities with the worst air quality, of which PM2.5 (refers to particles with an equivalent diameter of less than or equal to 2.5 microns in the ambient air) and ozone are the primary pollution emissions. At the same time, PM2.5 is converted from sulfur and nitrogen oxides, and these gaseous pollutants are often caused by the combustion of fossil fuels (coal, oil, petroleum coke powder, etc.). The combination of ozone and sulfur dioxide will produce sulfur trioxide, which will seriously pollute the air

"In the pollution of the glass industry, the emissions are mainly sulfur dioxide and dust, which have brought serious pollution to the atmosphere. Taking Shahe, a Chinese Glass City, as an example, many enterprises directly discharge sulfur dioxide into the air without desulfurization after burning coal. At the same time, they do not go through the treatment of dust removal equipment. Many kinds of fine particles produced without full combustion are also directly discharged into the air." A person familiar with the pollution in the glass industry said to

he also said, "The glass pollution in Shahe is actually quite harmful to the atmosphere in North China. It can be said that it is comparable to the air pollution caused by steel, cement, etc., but people pay more attention to the pollution caused by the production of steel, cement, thermal power, etc. in North China, and pay less attention to the pollution caused by the production of glass. There are so many workers in Shahe, an area where glass is intensively produced When the factory produces glass, it does not go through desulfurization and dust removal. It can be imagined how much impact it has on air pollution. This also explains why Hebei accounted for seven of the top ten cities with the worst air quality in the third quarter, and why smog days are so easy to occur. The nonstandard production of the glass industry in the field of environmental protection has seriously affected the quality of the atmosphere. "

the relevant glass enterprises in Guangdong have not changed after repeated inspections

if it is said that the entire glass industry in Shahe is "mutually agreed" to mainly burn coal and does not feel that there is any difference, then when visiting several major glass production companies in Guangdong, there is a huge difference in fuel, especially the visual impact

China Resources Glass Co., Ltd. is located in Hetang Town, Jiangmen City, Guangdong Province. Upon arriving at the town, it was easy to see the three "indomitable" chimneys of the company continuously emitting yellow and gray black smoke. As the distance from the company became closer and closer, waves of unpleasant smell came to our faces

it is understood that Hetang Town, Jiangmen City is located near Xijiang, Guangdong Province. In addition to the above-mentioned glass factory, the town mainly produces leather, hardware, etc. During the field visit, I saw many ships docked at the wharf, carrying all kinds of goods. When asked why the three chimneys of the glass factory emit such yellow and gray black smoke, the worker said, "The fuel of this glass factory is petroleum coke powder, and it often doesn't use environmental protection devices to treat the exhaust gas, so it's normal to emit smoke of this color. In fact, the government's environmental protection department has also checked it, but it will continue to secretly discharge after checking the side compartment. Moreover, the scale of this factory in the town is relatively large, which solves the employment problem of many people and pays more taxes to the government."

earlier, relevant media exposed that China Resources Glass Co., Ltd. in Hetang Town, Jiangmen City and Jiangmen Yisheng Float Glass Co., Ltd. illegally used petroleum coke powder as fuel and were investigated and punished by relevant environmental protection departments. Although it is impossible to go to the China Resources glass plant to confirm whether the fuel used by the company is petroleum coke powder, it is quite possible that the company has not been treated by environmental protection devices from the on-site environment and the color of chimney discharge

another Yufeng glass factory in Dongfeng Town, Zhongshan City, which has been exposed by the media, has seen two chimneys emitting gray and black exhaust gas before arriving at the company

according to relevant reports, the person in charge of the environmental protection branch of Dongfeng Town, Zhongshan City once said that the use of petroleum coke powder as the production fuel in Zhongshan Yufeng glass factory belongs to the normal range of use, and there is no violation. The person in charge also said that the burning of petroleum coke powder was in line with the regulations

according to relevant insiders in the glass industry, "In addition to the above-mentioned enterprises, there are many large, medium-sized or small glass manufacturers in Guangdong, such as Guangzhou Fumin Glass Co., Ltd., Guangdong Yingzhi plastic parts dehongtai Glass Co., Ltd., Qibin glass Heyuan production base, Guangdong Sihui xindaming Glass Co., Ltd., etc. in order to save costs, many of these glass manufacturers use petroleum coke powder as fuel, and some do not have environmental pollution discharge measures at all , even if there are environmental pollution discharge measures, some of them are often not put into use, which is just a sham. "

at the same time, it is noted that the villagers in Lankou Town, Dongyuan County, Heyuan City, Guangdong Province have reported and complained to the relevant departments of Heyuan City about the problems related to the large amount of waste gas, waste water, dust and other pollutants emitted by Qibin glass, which have seriously affected the living environment of the residents in the town. The relevant departments have ordered the company to rectify and some media have reported on this. However, some workers working in the factory in Lankou town reported, "if there is no relevant environmental protection department to check, the factory will directly discharge the waste gas. If there is a relevant department to check, they will use environmental protection measures such as desulfurization and dust removal. Just like a cat catching a mouse, a cat will be afraid when it comes, and if it doesn't come, it will continue to secretly discharge the waste gas."

coincidentally, when looking up the relevant information, it was found that Mianyang liuneng powder equipment Co., Ltd. published relevant words and pictures on the page. According to the description of these words and pictures, this Mianyang liuneng powder company is a manufacturer of special grinding machines for petroleum coke powder and other related machines, Many glass manufacturers have purchased the special grinding machine for petroleum coke powder produced by this company. In the list of glass companies that purchased Mianyang liuneng powder equipment, the above-mentioned glass industry insiders said that the relevant Glass Companies in Guangdong were all guests on the list

"in fact, compared with relevant inland enterprises, many glass enterprises in Guangdong are fully qualified to use natural gas as fuel, but many glass factories continue to burn highly polluting fuels such as petroleum coke powder in order to save costs regardless of environmental pollution." Guangdong glass industry insiders said

fuel economy account behind pollution, "At present, according to the fuel situation of the glass industry in China, there are four main types, namely, natural gas, heavy oil, coal and petroleum coke powder. Natural gas is a kind of light pollution, which does the least harm to the environment, and the discharged waste gas does not need to be desulfurized. Heavy oil is a kind of moderately polluted waste gas, which needs to be desulfurized. Coal and petroleum coke powder are highly polluted waste gas. If there is no desulfurization, it will do great harm to the environment."

he also said, "In Shahe, the production of glass mainly depends on coal because of its environment. There are abundant coal resources here. If it is very difficult for factories in Shahe to burn natural gas, first of all, the hardware facilities are not available. But burning coal does not mean that the problem of environmental protection can be completely ignored. At least, the environmental protection measures such as desulfurization and dust removal devices in these factories must be used, and if conditions permit Heavy oil, a relatively less polluting fuel, should also be used. "

"the reason why so many glass companies use coal, petroleum coke powder, etc. as their main fuel is that in order to save costs, the cost is closely related to the enterprise, while environmental protection is an uninvited guest in the eyes of the enterprise."

the person simply calculated the economic account between the four fuels. If the same 500t/d (daily melting capacity) float glass production line uses standard coal as fuel, the annual consumption is about 54750 tons/year, and the price of each ton of coal is about 500 yuan, the total annual fuel cost is about 2800 yuan
