Fighting the "Blue Sky Defense War", Wuhan's "careless" is compared with organic exhaust gas

The Yangtze River Daily Da Wuhan Client July 9th. On the 8th, the Municipal Ecological Environment Bureau held a grant ceremony and performance rating training meeting for enterprises in key pollution weather industries. Wuhan is "scaring", and the discharge of "organic exhaust gas" is fully pressed to comprehensively improve the air quality.

At the meeting, Luo Wei, chief engineer of the Municipal Ecological and Environment Bureau, encouraged more enterprises to rectify, accelerate the bidding, upgrade, and upgrade the ranks of environmental performance A, B -level companies, and leading enterprises as soon as possible. Contribute.

The generation of severe pollution weather is directly related to volatile organic matter (VOCS). This is an important predecessor of ozone, including a variety of "organic exhaust gas", which has an important impact on air quality, and it is difficult to governance and high governance costs. At present, the main method is to reduce its usage and emissions concentration as much as possible.

The only A -level enterprise awarded this time is SAIC -GM's Wuhan Branch. This is also the first automotive manufacturing company in Hubei to perform heavy pollution weather performance A.

According to reports, in the car paint spraying link, when the spray paint color needs to be replaced, the semi -water base cleaning agent containing volatile organic matter needs to be used to repeatedly clean the spraying equipment.

In order to reduce the emissions of pollutants from the source, early last year, SAIC -TOEINING has organized a joint innovation group of more than 10 people. After 8 months of R & D and commissioning, repeated cross -experiments among more than 20 kinds of raw materials, and finally more than 100 from more than 100 raw materials. A optimal formula is selected in the specification. The proportion of cleaning agents and water in this birth to 6:94, its VOCS content drops from 149g/L to 37g/L, which saves the amount of solvent and reduces costs. 17 tons of volatile organic matter. At present, this technology is at the leading level of the industry, and SAIC -GM has promoted the use of this low VOCS water base cleaning solvent.

"Don't underestimate these 17 tons." The person in charge of the Atmospheric Environment Office of the Municipal Ecological Environment Bureau introduced that the target of volatile organic matter during the "Fourteenth Five -Year Plan" period of Wuhan was 7,000 tons, which is equivalent to 1400 tons per year. Only in this regard "care" in this regard can this "blue sky defense war".
