Shishi Printing And Dyeing Industry Has Stepped Up To A New Stage In Environmental Protection And Energy Conservation

Yesterday, reporters learned from the Shishi dyeing and finishing industry association that this year is the stone lion dyeing and printing industry "setting machine". Environmental protection and energy saving "Technology year", so far, the printing and dyeing industry in Shishi has installed, installed or planned to install more than 100 sets of exhaust gas purification heat recovery equipment, and the energy conservation and environmental protection work of the printing and dyeing industry has been stepped up. New step 。

The printing and dyeing industry is the most important task of energy saving and emission reduction in Shishi. Its water consumption, coal consumption, electricity consumption and pollutant discharge are large. Printing and dyeing industry The consumption of water accounts for more than half of the city's industrial water consumption, and so does the consumption of coal. Due to the constraints of resources and environment, Shishi dyeing and printing enterprises realize that energy conservation and emission reduction is an important measure to alleviate resource and environmental constraints. The centralized daily processing capacity of industrial wastewater in Shishi's printing and dyeing industry is more than 200 thousand tons, and the treatment of printing and dyeing waste gas is on the agenda. Shishi Qingyuan dyeing and printing chairman Wang Qingyuan and other knowledgeable entrepreneurs pointedly pointed out: setting machine is the key point for printing and dyeing enterprises to treat industrial waste gas. Under the proposal of Shishi printing and dyeing enterprisers, the Shishi dyeing and finishing industry association established 2011 as the "environmental protection and energy saving technology year" for printing and dyeing industry, striving for a new breakthrough in the environmental protection undertaking of Shishi printing and dyeing industry in the first year of the 12th Five-Year plan.

The original intention of Shi Shi printing and dyeing enterprisers on stereotype exhausts is to be socially responsible, responsible for the environment and responsible for history. Setting machine is a necessary equipment for knitted, long car and chemical fiber printing and dyeing enterprises. The odor in the air of printing and dyeing plant is emitted from the stereotype machine. There is already a mature set of tail gas treatment equipment for stereotype machines imported from abroad. It needs a set of RMB 1 million -200 yuan per set. Shishi printing and dyeing enterprise has fewer than 2-3 set machines and more than ten sets of stereotypes. With the cooperation of various environmental protection technology institutions in China, the Shishi printing and dyeing enterprise has successfully tackled key problems, and eventually developed various mature machine exhaust treatment devices. Each investment cost is only about 200 thousand yuan, far lower than that of similar foreign devices. Its effect is no less than that of similar products abroad, and will soon be popularized in the printing and dyeing industry of the whole city. It is understood that there are 7-8 environmental technology institutions in the Shishi printing and dyeing industry to cooperate with the enterprise equipment and debugging stereotype exhaust treatment device. Only one set of Boyi environmental protection technology company has installed 40 sets of exhaust gas treatment equipment in 8 dyeing and finishing factories in Jin Shang Zhen.

The stereotype exhausts treatment device has the characteristics of relatively less investment, high recycling rate and good environmental protection effect. According to Li Weiqing, chief engineer of Boyi environmental protection technology, the main purpose of the "heat recovery device for exhaust gas purification of stereotypes" is to purify industrial waste gas, block the harmful substance gas containing many complex components to discharge into the air, but at the same time, it can recover heat, hot water and grease to achieve the effect of three arrows. After testing, the exhaust gas purification rate is over 90%, the recovery rate of waste heat temperature is over 85%, the hot water dosage is 70 tons -120 tons / day, the soot collection rate is over 92% (the market purchase price of waste oil is 2000-2500 yuan / ton), which integrates environmental protection, economy and reusability as a whole. After the investment, the enterprise can recover the investment in about 1-1.5 years, save electricity, save coal, save steam and save water. The unity of economic benefits and social and environmental benefits has been achieved. Energy conservation, emission reduction, environmental protection and cleaner production are also productive forces. This is a new harvest for printing and dyeing enterprises in the work of energy conservation, emission reduction and environmental protection. Now, entering the printing and dyeing mill, there is no smell in the air. This is the credit for the technical transformation of the stereotype machine. Before long, Shishi printing and dyeing industry will soon popularize the "heat recovery device for exhaust gas purification of stereotyping machines". This is a major achievement of the Shishi printing and dyeing industry consciously fulfilling its social responsibility system without the administrative order.
