New Policy To Promote Energy Saving And Emission Reduction In Shishi Printing And Dyeing Industry

< p > reporter learned yesterday from the city dyeing and finishing association that the Ministry of environmental protection has issued four guiding documents and has listed the "air pollution control" as the focal point. Among them, the document close to Shishi < a href= "//www.sjfzxm.com/news/index_c.asp" > printing and dyeing industry < /a > is "volatile organic compounds (VOCs) pollution prevention and control technology policy".

< /p >

< p > the technical policy for prevention and control of volatile organic compounds (VOCs) pollution is a guiding document with a date of implementation in May 24, 2013.

The document requests: by actively carrying out the VOCs investigation, making and revising the VOCs emission standards and management systems of key industries, strengthening VOCs monitoring and management, and promoting the use of environmental labeling products and other measures, by 2015, the VOCs pollution prevention and control system in key areas has been basically established. By 2020, the whole process of reducing emissions from raw materials to products, from production to consumption has been basically realized.

< /p >

< p > VOCs emission from industrial sources involves many industries. At present, there is a lack of authoritative emission list. < a target= "_blank" href= "//www.sjfzxm.com/" > textile > /a > printing and dyeing is one of the key industrial sectors in the industrial source.

The types and composition of VOCs pollutants emitted by printing and dyeing industry seem to be complicated. The composition of the printing and dyeing industry seems to be unstudied, but it is certain that sour gas, common organic matter and odor gas are contained.

The gas pollutants in Shishi printing and dyeing industry are often discharged in the form of high temperature gas mixture. The exhaust gas source recognized by the industry is the high temperature setting machine. The exhaust gas treatment of the stereotype machine is the key to the treatment of industrial gas pollutants in the printing and dyeing industry. This has become a consensus.

< /p >

< p > the printing and dyeing industry in Shishi has carried out the activity of "high temperature stereotype machine tail gas control year". More than 100 of the more than 300 stereotyping machines in the printing and dyeing industry have been effectively treated and promoted the technological progress in the prevention and control of volatile organic compounds (VOCs) pollution.

In the compilation of "technical policy for prevention and control of volatile organic compounds (VOCs) pollution", the VOCs purification unit technology includes adsorption technology, condensation technology, plasma destruction technology, photocatalytic technology, membrane separation technology, absorption technology, catalytic combustion technology, thermal incineration technology and biotechnology. Some technologies have been applied in production practice, and achieved good results. Some technologies are still in the experimental stage, and some enterprises have adopted other technical means, such as ozone technology.

< a href= "//www.sjfzxm.com" > Shishi printing and dyeing < /a > enterprises in the industrial waste gas treatment, based on the principle of practicality, each has its own way and has various technical routes, but it has the same effect as the same way.

< /p >

< p > Shishi each a href= "//www.sjfzxm.com/news/" > printing and dyeing enterprise < /a > is in accordance with the comprehensive management and recycling economy principle of tailor machine exhaust treatment, the primary goal is to substantially reduce the emission of industrial gas pollutants. The result is the elimination of odor and odor from the atmosphere. The common practice of different enterprises is to exhaust exhaust heat recovery, the working temperature of the molding machine reaches 250 degrees Celsius, the steam temperature after recovery is about 150 degrees Celsius, and then is used for dyeing process. Different enterprise needs are different, and the technical methods are also different, such as Ling Feng bleaching and dyeing to pay attention to oil and gas recovery, and waste oil recovery funds to offset the investment of stereotype pformation.

< /p >

< p > it is understood that the state will also introduce a "national air pollution control action plan" with a higher standard. The current policy is only "opening remarks". A series of national environmental policy "combination boxing" will undoubtedly promote the development of energy saving and emission reduction and cleaner production in Shishi printing and dyeing industry.

But there is one thing that no one has done yet, and the enterprises are unwilling to do it alone. It is suggested that the government or industry should conduct a thematic study on the composition and content of the exhaust gas in the printing and dyeing industry in order to adopt the most appropriate printing and dyeing waste gas treatment technology.
