SMM News: according to the official WeChat news of Tianjin Ecological Environment Bureau, recently, the Tianjin Environmental Administrative Law Enforcement team conducted surprise night checks on some iron and steel enterprises and found that five enterprises were suspected of environmental violations. At present, it is being investigated and dealt with, and those who do break the law will be punished on file.
According to the Tianjin Ecological Environment Bureau, the five steel enterprises are Tianjin Metallurgical Group Rolling three Iron and Steel Co., Ltd., Tianjin Tianfeng Iron and Steel Co., Ltd., Tianjin Steel Pipe Iron and Steel Co., Ltd., Tianjin Tianzhong Jiangtian heavy Industry Co., Ltd., Tianjin Iron and Steel Group Co., Ltd.
In the surprise night investigation, the dust collection cover at the single roll cloth of No. 1 sintering machine of Tianjin Metallurgical Group Rolling No. 3 Iron and Steel Co., Ltd can not collect dust completely, some materials leak, there is dust unorganized emission, the material yard is in a semi-open or open state, the stacker is stacking in the material yard (Article 6), there are no dust collection facilities, and the ground dust is serious. The observation port of CC2 dust collector is not strictly closed, dust dissipates and spills to the external environment; opposite the material yard (south of the raw material middle road), there is a large amount of steel slag stacked in the open air, part of the steel slag is not covered, and there are no other dust suppression measures.
The enterprise is suspected of the following illegal acts: suspected of failing to take effective measures to prevent and control dust pollution; suspected of failing to take measures to prevent dispersion, loss, leakage or other measures to prevent pollution of the environment; suspected of failing to carry out self-monitoring in accordance with the regulations and keeping the original monitoring records; suspected of failing to guarantee the normal operation of automatic monitoring equipment for pollution sources, etc.
When Tianjin Tianfeng Iron and Steel Co., Ltd. was inspected, a 150 square meter sintering machine was in production, and some of the dust produced in the process of unloading and crushing was not collected by the gas collecting cover and escaped to the sintering workshop, where the windows were open. It is suspected of not taking measures such as sealing, enclosure, covering, cleaning, sprinkling, etc., to reduce the discharge of dust and gaseous pollutants produced by the storage, transmission, loading and unloading of internal materials.
Tianjin Steel Pipe Iron Co., Ltd. No. 6 silo dust collection cover soft curtain is in the open state, dust collection cover outside the dust accumulation is obvious; No. 9 No. 10 silo dust removal facilities pipe is broken, the dust generated in the blanking process can not enter the dust removal facilities; in addition, a number of external windows of the batching workshop are open; the dust collection cover of the dust collection facilities matching in the secondary screening process is damaged and the dust does not escape in an organized way. It is suspected of abnormal operation of pollutant treatment facilities.
During the inspection, Tianjin Tianzhong Jiangtian heavy Industry Co., Ltd. is in production, blast furnace, converter, sintering equipment is in operation. In the sintering yard, there are some iron ore powder, 1 car dolomite powder, 2 cars iron oxide scale and 1 car coal ash cover at the entrance of the sintering yard. It is also found that the side baffle of the slag outlet of the east outlet of the blast furnace is not closed, resulting in the abnormal operation of dust removal facilities, resulting in smoke and dust escaping to the external environment. The company is suspected that dust-prone materials have not taken effective cover measures to prevent and control dust pollution.
In addition, in the inspection of Tianjin Iron and Steel Group Co., Ltd., 265m2 sintering machine is in operation, its tail bag dust removal facilities are not complete, part of the dust does not enter the dust removal facilities, unorganized discharge; 3200 cubic meters of blast furnace slag system dust collection is incomplete, unorganized emission; 2000 cubic meters of blast furnace dust did not enter the collection device, unorganized discharge. The company is suspected that some of the dust did not enter the dust removal facilities unorganized emissions.
