Energy-saving and environment-friendly dust removing system for asphalt concrete stirring station

Abstract

The invention discloses an energy-saving and environment-friendly dust removing system for an asphalt concrete stirring station. The energy-saving and environment-friendly dust removing system comprises a temperature control device (1), a cloth-bag dust removing device (2) and a spraying and dust-removing device (3) which are connected in sequence, wherein the temperature control device (1) is connected with a waste-gas outlet and comprises a hollow liner (14) and a shell, and a circulating pipeline (15) is arranged between the shell and the liner (14); a temperature sensor (13) is arranged between the temperature control device (1) and the cloth-bag dust removing device (2); the spraying and dust-removing device (3) comprises a shell, a filtering net (31) and a spraying nozzle (33); the filtering net (31) and the spraying nozzle (33) are arranged in the shell; and the spraying nozzle (33) is connected with a water pipe (32) and is arranged above the filtering net (31). The energy-saving and environment-friendly dust removing system disclosed by the invention has the advantages that the dust-removing effect for waste gas is good, the temperature of the waste gas can be effectively controlled and the service life of the dust removing equipment is prolonged.

Description

technical field [0001] The invention relates to the field of asphalt concrete production equipment, in particular to an energy-saving and environment-friendly 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,...

Problems solved by technology

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 the exhaust gas flow in, or the dust heats up, and the filter bag may also be burnt into holes. Replacement, if the temperature of the gas entering the bag filter is too low, it will condense when it enters the waste gas treatment device, which will affect the filtering effect
