Spraying device for environment-friendly waste treatment

Abstract

The invention discloses a spraying device for environment-friendly waste treatment. The spraying device comprises a box body, a fixing column is arranged on the outer wall of one side of the box body,a water storage tank is arranged on the outer wall of one end of the fixing column, a gas inlet pipe is inserted into the inner wall of the top of the water storage tank, one end of the gas inlet pipe extends into the box body, and a liquid return pipe is inserted into one end of the box body; a liquid storage tank is inserted into one end of the liquid return pipe, a connecting pipe is insertedinto the outer wall of the top of the liquid storage tank, a water pump is inserted into one end of the connecting pipe, a spray pipe is inserted into the outer wall of the top of the water pump, spray heads distributed at equal intervals are inserted into the outer wall of the bottom of the spray pipe, and a motor is arranged on the outer wall of one side of the box body. A large amount of heat carried in waste gas in the gas inlet pipe can be absorbed through the water storage tank, resource waste caused by direct heat emission is avoided, meanwhile, the cross section of the gas inlet pipe is S-shaped, the contact time of the waste gas and water can be prolonged, and the waste heat recovery effect is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection waste treatment, in particular to a spray device for environmental protection waste treatment. Background technique [0002] Industrial waste gas is one of the important components of waste, and waste gas treatment is also called waste gas purification. Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before being discharged to the outside, so as to meet the national standards for external discharge of waste gas. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air sterilization, disinfection and purification. [0003] Since the exhaust gas will carry a lot of heat in the process of generation, the general exhaust gas treatment device does not have the function of waste heat recovery, which will easily lead to a larg...

AI Technical Summary

Problems solved by technology

[0003] Since the exhaust gas will carry a large amount of heat during the generation process, the general exhaust gas treatment device does not have the function of waste heat recovery, which will easily lead to a large amount of heat loss in the exhaust gas, resulting in energy waste

At the same time, when the traditional exhaust gas treatment device sprays and purifies the exhaust gas, the direct contact between the exhaust gas and the absorption liquid is not sufficient, which leads to a great decline in the purification effect of the device on the exhaust gas.
