Upgrading Of Printing And Dyeing Enterprises In Keqiao

In recent days, Zhejiang Huachen printing and dyeing Co., Ltd., on the roof of the two workshop, the staff are busy debugging the stereotype exhaust gas treatment equipment. "The best equipment is to go up." Wei Zhijiang, general manager of the company, said that at present, all the waste gas treatment devices of all stereotypes and printing machines have been upgraded to five levels in the leading industry. Particulate matter, dyeing and finishing fumes and VOCs in the exhaust gas all conform to the air pollution emission standards of the textile dyeing and finishing industry.

"Brilliance printing and dyeing" was put into operation in April 2018. It is the three phase in the printing and dyeing gathering area. "Agglomeration is not only a simple relocation, but also a comprehensive upgrading of plant design, piping layout and production process." Wei Zhijiang said that to change the stereotype of pollution in traditional printing and dyeing industry and create a new high-end and world leading image of Keqiao's printing and dyeing industry, every printing and dyeing enterprise needs to take the initiative, and gathering is just an opportunity. Since its commissioning, the company has also closed management of the smelly and other odor prone workshop, and equipped with VOCs waste gas treatment equipment. In recent years, the waste gas treatment equipment has invested more than 20 million yuan.

"Brilliance printing and dyeing" on the waste gas treatment initiative to pull up the benchmarking, practice green environmental protection concept is not a case. In Keqiao Tianyu printing and dyeing Co., Ltd., after the disposal of the exhaust gas from the stereotype machine, the white smoke of the exhaust port was also lost. "Enterprises invest more than 30 million yuan in waste gas treatment equipment." Wu Jiadi, general manager of the company, said that industrial waste gas remediation should rely not only on government supervision, but also on enterprises' consciousness. In recent years, the company has been working on the most advanced exhaust gas treatment equipment from Taiwan Europe's letter machine's exhaust gas treatment equipment to the five stage stereotyping machine exhaust gas treatment equipment of China's Heng Hui company. Before the three level treatment process of "water spray + cooling + static electricity", the company has been working hard to increase industrial waste gas. The removal rate of particulate matter and VOCs in the exhaust gas is more than 90% after the filtration process and the "de white" treatment.

From passive to active, the transformation of enterprise concept can not be separated from the guidance and supervision of the government. In recent years, in order to implement the three year action plan (2018-2020) of the blue sky defense campaign in Shaoxing, we should do our best to prevent and control the air pollution in the printing and dyeing gathering area. The Ma Ma Street starts to carry out the special rectification action to win the blue sky defense campaign, with the deepening of the industry waste control as a breakthrough, and continuously promote the deep treatment of industrial waste gas in key enterprises, and draw up a rectification plan of "one enterprise and one strategy" for waste gas remediation. The case is for on-line monitoring of all the waste gas treatment facilities in printing and dyeing enterprises, improving the sign of exhaust gas direction, starting the "card type" management of the setting machine, and responding to the key enterprises such as "Tianyu dyeing", "Alice dyeing and finishing", "red and green blue textile" and "Ze Ping printing and dyeing". At present, there are 858 sets of waste gas treatment facilities equipped with 2351 sets of stereotypes in printing and dyeing areas, of which four or more are 22.4%.

According to the introduction, the main index of air quality in printing and dyeing industry gathering area in 2019 was PM2.5 38ug/m3, and PM2.5 concentration dropped to 31ug/m3 in 1-4 months this year, and the air quality was greatly improved. Next, Ma On Street will also start natural gas fired boiler low nitrogen transformation and other activities, in-depth implementation of fine particulate matter and ozone concentration "double control and double reduction" to further improve the air quality.
