Abstract

The invention discloses a dedusting system. The dedusting system is used for asphalt-concrete stations, and comprises a temperature control device (1), a cloth bag dedusting device (2), and a spray dedusting device (3) which are connected successively; the temperature control device (1) is connected with an exhaust gas outlet; the temperature control device (1) comprises a hollow inner container (14), and a housing; a circulation line (15) is arranged between the housing and the hollow inner container (14); a temperature sensor (13) is arranged between the temperature control device (1) and the cloth bag dudusting device (2); the spray dedusting device (3) comprises a housing body, and a filter screen (31) and a nozzle (33) arranged in the housing body; the nozzle (33) is connected with a water pipe (32), and is arranged above the filter screen (31). Dedusting effect of the dedusting system on exhaust gas is excellent; the temperature of exhaust gas can be controlled effectively; and service life of dedusting equipment is prolonged.

Description

technical field [0001] The invention relates to the field of asphalt concrete production equipment, in particular to a dust removal system. Background technique [0002] In the concrete industry, asphalt concrete mixing plants are used to produce asphalt concrete. Equipment mainly used on roads. The main function is to mix asphalt, crushed stone, mineral powder and fiber together in a certain proportion, and heat it to the mixing temperature for mixing. The original concrete mixing plant equipment is large and heavy. During the production process, a large amount of high-temperature dust gas is generated, and the waste gas is mainly treated by bag dust removal. However, the dust removal effect of the existing dust removal equipment is poor. At the same time, due to the temperature of the dust gas Without control, when the temperature of the gas entering the bag filter device is too high, it is easy to harden and shrink the filter bag, or melt to create holes, and sparks in ...
