Abstract

The invention provides a reclaimed sand dedusting system which can effectively purify dust-containing gas, has good dedusting effect and carries out further treatment on purified gas so as to prevent dust-containing gas from secondary diffusion, which is beneficial for environmental protection. The reclaimed sand dedusting system is characterized in that the reclaimed sand dedusting system comprises cyclone dusters, an exhaust fan and a pool which are sequentially connected through pipelines; at least two cyclone dusters are arranged and are connected with each other in series, and a discharge pipe of the front cyclone duster is connected with an air inlet pipe of the rear cyclone duster; an outer cover is arranged above the pool; and the top of the outer cover is connected with a chimney.

Description

technical field

[0001] The invention relates to the technical field of regenerated sand production, in particular to a regenerated sand dust removal system. Background technique

[0002] The foundry industry will discharge a large amount of solid waste during production, which is mainly waste sand. With the development of the industry, various organic and inorganic binders are widely used, resulting in more and more harmful components contained in waste sand. For example, residual aldehyde, phenol, benzene, potassium, isocyanide, sulfide, etc. in the waste sand of organic resin binder, and harmful components such as alkali and phenol remaining in waste sand of inorganic binder. Waste sand containing such harmful components will be eroded by rainwater after discharge, and its harmful components will pollute rivers and lakes, and even pollute domestic water sources. Recycling and recycling waste sand can save valuable new sand resources, is beneficial to environmental pro...
