AI Technical Summary

Problems solved by technology

Moreover, activated carbon adsorption requires frequent replacement of activated carbon materials, and has a certain impact on system pressure
The cost of the plasma dust collector is high, the wet dust removal effect is poor, and there are still disadvantages such as that it cannot be adjusted according to the working conditions, resulting in too much water consumption, the removal of harmful gases cannot be achieved, and the cement slurry is not easy to clean.

Abstract

The invention relates to a dedusting system and an asphalt mixing station. The dedusting system comprises an ash hopper bin (2) and a dedusting spraying mechanism, wherein the ash hopper bin (2) is communicated with a pipeline (1) through which dust-containing gas flows; the dedusting spraying mechanism is arranged on the inner side of the pipeline (1), is positioned on the upper side of the ash hopper bin (2) and is used for spraying dedusting liquid from a dedusting liquid supply source on the dust-containing gas flowing in the pipeline (1), so that the dedusting liquid is enabled to react with dust in the dust-containing gas and falls into the ash hopper bin (2) after adsorbing the dust. According to the embodiment of the invention, the dedusting effect can be improved.

Description

technical field [0001] The present disclosure relates to the field of engineering machinery, in particular to a dust removal system and an asphalt mixing plant. Background technique [0002] With a large number of infrastructure construction projects and a large number of renovations on old roads, the demand for asphalt mixture is increasing. Based on the needs of energy saving, emission reduction and environmental protection, the technical performance index requirements for asphalt mixing plants are also getting higher and higher. Most of the current asphalt mixing plants adopt two-stage dedusting methods, that is, gravity dedusting + bag dedusting. Although most of the dust can be removed after these two stages of dust removal, the fine particles below PM10 cannot be completely removed. If these fine particles are discharged directly, they will endanger human health. In addition, the dusty gas also contains exhaust gas after burner combustion, which contains acid gas, w...
