Textile bleaching and dyeing exhaust-gas treatment plant

Abstract

The invention discloses a textile bleaching and dyeing exhaust-gas treatment plant, which comprises a first tank, a second tank, a suction pump, a cooler, a connecting pipe, a spray device, a first cover, an air inlet pipe, an air outlet pipe, a water inlet and a water outlet. By arranging the two tanks, exhaust gas entering the first tank through an air inlet undergoes first-stage spray purification adsorption through the spray device, and granular pollutants in the exhaust gas are adsorbed by sprayed water; the exhaust gas treated in the first tank is pumped into the second tank through thesuction pump, and the exhaust gas passes through water in the second tank to undergo second-stage adsorption; through an active carbon device arranged at an exhaust port, the exhaust gas can undergo third-stage adsorption, and irritant smell of the exhaust gas can be reduced effectively; and through the cooler arranged on the outer wall of an exhaust pipe, the discharged exhaust gas can be cooled,and water vapor in the exhaust gas is condensed so as to reduce water content of the exhaust gas. In comparison with a traditional technology, the invention has the following advantages: the textilebleaching and dyeing exhaust-gas treatment plant has a simple structure and has better exhaust gas treatment effects, and pollution is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of environmental protection equipment, especially the technical field of waste gas treatment. 【Background technique】 [0002] In order to prevent the deterioration of the natural environment and protect the green mountains, green water, blue sky, and sea, people pay more and more attention to environmental protection issues. Textile waste gas contains a large amount of harmful smoke, silicone oil, fiber, dye auxiliaries, and industrial acids and alkalis. The composition has brought a certain degree of pollution to the atmospheric environment. China is a large textile country, and there are more than 2,000 bleaching and dyeing enterprises above designated size. In these bleaching and dyeing enterprises, there are several to a dozen setting machines. A large amount of waste gas will be discharged during the production process of finalizing the shape. The waste gas contains a large amount of harmful component...

[0002] In order to prevent the deterioration of the natural environment and protect the green mountains, green water, blue sky, and sea, people pay more and more attention to environmental protection issues. Textile waste gas contains a large amount of harmful smoke, silicone oil, fiber, dye auxiliaries, and industrial acids and alkalis. The composition has brought a certain degree of pollution to the atmospheric environment. China is a large textile country, and there are more than 2,000 bleaching and dyeing enterprises above designated size. In these bleaching and dyeing enterprises, there are several to a dozen setting machines. A large amount of waste gas will be discharged during the production process of finalizing the shape. The waste gas contains a large amount of harmful components such as smoke, silicone oil, fiber, dye auxiliaries and industrial acid and alkali, which brings a certain degree of pollution to the atmospheric environment. It adopts the electrostatic adsorption method, and uses the electrostatic adsorption method to absorb waste such as fibers, waste oil, bleaching and dyeing auxiliaries in the exhaust gas. The equipment investment of the electrostatic adsorption method is large, the energy consumption is high, and the treatment cost is high. Generally, small enterprises cannot afford the high cost. Waste gas treatment cost, the other is the spray method, the cost of the spray method is small, but the effect of waste gas treatment is average, and the effect of pollutant removal is not good
