Problems solved by technology

The existing device needs to spray adsorbent on the surface of the filter material layer in advance to deal with the adhesive gas. After working for a period of time, in order to ensure the passing rate of the flue gas, it is necessary to remove the used adsorbent to clean the filter material layer; After the adsorbent

Embodiment Construction

[0020] The present invention will be further described below through specific embodiments.

[0021] refer to Figure 1 to Figure 2 As shown, an environment-friendly asphalt smoke adsorption treatment device includes a box body 1, the box body 1 is provided with an air inlet 11 and an air outlet 12, and the box body 1 is sequentially provided with a buffer shunt between the air inlet 11 and the air outlet 12 Zone 2, powder layer 3, bag filter layer 4.

[0022] The powder material layer 3 comprises a porous air-permeable plate 31 and a powder material 32 arranged on the top surface of the porous air-permeable plate 31. When the asphalt smoke passes through the porous air-permeable plate 31 and passes through the powder material 32, the asphalt smoke is adsorbed for the first time. Under the impact of the asphalt fume, it flies up to the bag filter layer 4 to form a layer of powder protection layer. When the asphalt fume passes through the bag filter layer 4, it undergoes second...

Abstract

The invention relates to the technical field of exhaust gas treatment, and in particular, relates to an environmentally friendly asphalt fume adsorption treatment device and method. The device comprises a box body which is provided with an air inlet and an air outlet; the device is characterized in that the box body is provided with a powder layer and a cloth bag filter layer in turn from the airinlet to the air outlet, and the powder layer includes a porous air permeable plate and a powder arranged on the top surface of the porous air permeable plate, and asphalt fume is adsorbed for the first time when passing through the powder after passing through the porous air permeable plate; the powder forms a powder protection layer on the cloth bag filter layer, and the asphalt fume is adsorbedfor the second time when passing through the cloth bag filter layer. The contact area of the powder in the boiling state with the asphalt fume is greater, and the adsorption efficiency of the powderis higher. The powder protection layer on a filter cloth bag is uniform and compact, and the replacement velocity is fast; the reutilization of the powder does not produce secondary pollution.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an environment-friendly asphalt fume adsorption treatment device and method. Background technique [0002] During the production of asphalt mixing equipment, asphalt, heavy oil, stone, etc. will volatilize flue gas, water vapor, dust and other polluting waste gas. In engineering, it is generally treated and discharged by bag dust removal equipment. Due to the high viscosity of asphalt flue gas , when passing through the bag of the bag dust removal equipment, it will cause the bag to appear "paste bag", which will lead to the reduction of the effective filter area of ​​the bag, and the decrease of the effective filter area will lead to the acceleration of the local air flow of the bag, accelerate the wear of the bag, and reduce the wear of the bag. If the bag is damaged, it will lead to equipment failure, resulting in substandard emissions and polluting the environment...
