Problems solved by technology

[0004] However, the above methods have their own shortcomings: the plasma method adopts high-voltage discharge method, and the safety cannot be guaranteed in the treatment of flammable and explosive organic waste gas. There have been many explosions in the treatment of organic waste gas by plasma method; activated carbon adsorption The method cannot solve the problem of regeneration after adsorption saturation; both catalytic combustion method and catalytic oxidation method need to heat the exhaust gas to the reaction temperature of the catalyst, which requires high energy consumption and the use of a large amount of catalyst

Embodiment 1

[0031] see Figure 1~4 , in the embodiment of the present invention, an industrial waste gas treatment device for organic pollutants, comprising a pretreatment box 3, a filter 7 and a liquid storage tank 13, the lower part of the pretreatment box 3 is provided with an air inlet 1, and the pretreatment box 3 is provided with an ash outlet 4, and a high-voltage pulse discharger 2 is also provided in the pretreatment box 3. The top of the pretreatment box 3 is connected to the filter 7 through the air outlet pipe 5, and the air outlet pipe 5 is connected to a polyacid The top of the hopper 6, the filter 7 is provided with an exhaust pipe 9, the exhaust pipe 9 is provided with an induced draft fan 8, and the bottom end of the filter 7 is connected to a liquid storage tank 13 through a liquid discharge pipe 15.

[0032] Such as figure 2 As shown, the inner lower part of the filter 7 is supported and fixed with a motor holder 25 by a support frame 24, and a double-axis extension m...

Embodiment 2

[0036] An industrial waste gas treatment system, comprising the organic pollutant industrial waste gas treatment device described in Embodiment 1.

[0037] In this organic pollutant industrial waste gas treatment device, the waste gas containing acid mist and organic pollutants first enters the pretreatment box 3 through the air inlet 1, and the gas passes through the pretreatment box 3 and the filter 7 in turn under the action of the induced draft fan 8, and the pretreatment The high-voltage pulse discharger 2 in the treatment box 3 implements high-voltage pulse discharge to generate ozone, ultrasound and ultraviolet radiation, and oxidizes and decomposes organic pollutants in the waste gas. Exhaust; then the exhaust gas enters the filter 7 along the outlet pipe 5, and at the same time, polyacrylamide powder is added to the exhaust gas of the outlet pipe 5 from the polyacid hopper 6; the exhaust gas mixed with polyacrylamide powder enters the filter 7 and passes through the fi...

Abstract

The invention relates to the technical field of waste gas treatment, in particular to a treatment device for organic contaminant industrial waste gas. The treatment device comprises a filter device, adouble-axis stretching motor is fixedly installed on a motor fixing base on the lower portion of the inner side of the filter device, a gas distributing plate is fixedly installed on a lower side output shaft of the double-axis stretching motor, a first filter net and a second filter net are each arranged on the upper portion of the inner side of the filter device from top to bottom, the space between the first filter net and the second filter net is filled with filling, the upper end of an upper side output shaft of the double-axis stretching motor is connected with a spraying pipe through arotating connecting part, multiple liquid spraying pipes are installed on the upper side output shaft of the double-axis stretching motor, and the other end of the spraying pipe is connected with a circulating spraying pump arranged at the bottom of the inner side of a liquid storage box. The treatment device can uniformly stir and distribute the waste gas and fully filter the waste gas, the range of spraying purifying is wide, spraying purifying is thorough, energy is saved, and environmental protection is realized.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an industrial waste gas treatment device for organic pollutants. Background technique [0002] With the rapid development of industry and deep processing of agricultural products, the types and quantities of waste gas have increased rapidly, and the pollution of the atmosphere has become increasingly widespread and serious, threatening human health and safety. Among them, the treatment of organic waste gas is a major problem in the environmental protection industry. [0003] Organic waste gas is generally flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat. At present, various methods such as organic waste gas adsorption treatment method, catalytic combustion method, catalytic oxidation method, acid-base neutralization method, plasma method, etc. are commonly used in the market. [0004] However, the ab...
