Embodiment 1

[0036] Such as figure 1 The device for treating organic waste gas with emulsion for treating organic waste gas shown includes an emulsion filled absorption tower, a circulation spray device, an oil-water separator, a demister and an induced draft fan, and the emulsion filled absorption tower is sequentially connected with a circulation spray The device is connected with the oil-water separator; the emulsion packed absorption tower is also connected with the demister and the induced draft fan in turn; the emulsion filled absorption tower, the demister and the circulating spray device are connected in sequence to form a circulation loop; the emulsion filled absorption tower and the The circulating spray device forms a circulating loop; the circulating spraying device and the oil-water separator form a circulating loop.

[0037] The method for treating organic waste gas with the above-mentioned device comprises the following steps in sequence:

[0038] A. After being first absor...

Embodiment 2

[0046] It is basically the same as Example 1, except that the mass concentration of the emulsion used is 4%, and the emulsion contains polyoxyethylene sorbitan fatty acid ester, sorbitan with a mass ratio of 4:2:1 Fatty acid esters and sodium polyoxyethylene lauryl ether sulfate.

[0047] Into the device, the concentration of 800mg / m 3 Butyl acetate gas, control the gas-liquid ratio (Nm 3 / m 3 ) is 6000 for 24 hours;

[0048] The discharge of butyl acetate after treatment by the above device is about 20mg / m 3 (Using gas chromatography to measure GB / T16069-1995 (national testing standard) detection), in line with the "Comprehensive Emission Standard of Air Pollutants" (GB16297-1996), the highest removal rate of butyl acetate is 97.5%.

Abstract

The invention aims to provide an emulsified liquid for processing organic waste gas, a device for processing the organic waste gas and a method for processing the organic waste gas. The emulsified liquid comprises polyoxyethylene sorbitan aliphatic ester or sorbitan aliphatic ester or a mixture of polyoxyethylene sorbitan aliphatic ester and orbitan aliphatic ester according to any ratio. The device for processing the organic waste gas comprises an emulsified liquid packing absorbing tower, a circulating spray system, an oil-water separator, a demister and an induced draft fan, wherein the emulsified liquid packing absorbing tower is successively connected with the circulating spray system and the oil-water separator; the emulsified liquid packing absorbing tower is also successively connected with the demister and the induced draft fan, the emulsified liquid packing absorbing tower and the circulating spray system can form a circulation loop, and the circulating spray system and the oil-water separator can form the circulation loop. The device for processing the organic waste gas provided by the invention has the advantages that the structure is simple, the use is convenient, the efficiency of removing the organic waste gas by the emulsified liquid can achieve 90%-99%, and meanwhile, the dust particulate matter removing efficiency is high.

Description

technical field [0001] The invention relates to an emulsion for treating organic waste gas, a device for treating organic waste gas and a method for treating organic waste gas, belonging to the technical field of waste gas purification. Background technique [0002] Air pollution is one of the most prominent environmental pollution problems in my country at present. Industrial waste gas is the main source of air pollutants, which has serious harm to agriculture, social environment, natural environment and people's health. Organic waste gas is one of the most difficult gases to control in industrial waste gas. Various organic waste gases will be produced in industrial production, mainly including various hydrocarbons, alcohols, aldehydes, acids, ketones and amines, etc. Organic waste gas will pass through When the respiratory tract and skin enter the human body, it can cause temporary and permanent lesions to human respiratory, blood, liver and other systems and organs, endan...
