Abstract

The invention discloses an integrated tail gas and waste powder treating apparatus of a complete set of equipment for regeneration and stirring of asphalt. The integrated tail gas and waste powder treating apparatus comprises a water foam sprinkling chamber, a recovered powder-tail gas mixing chamber, a waste powder humidification device, a deduster and a recovered powder conveying device. During operation, tail gas undergoes the preliminary treatment of sprinkling of primary water foam, so humidity of the tail gas is improved; then the tail gas fully contacts with adheres onto waste power (i.e., recovered powder) from the deduster, so harmful gas in tail gas of regenerated asphalt is removed, and the recovered powder falls into the waste powder humidification device; the waste powder and waste water obtained after primary treatment are mixed under stirring via the waste powder humidification device so as to form mud convenient for transporting and burying; thus, the waste gas and waste powder are treated. The integrated tail gas and waste powder treating apparatus has the advantages that the recovered powder and the tail gas of regenerated asphalt are treated in one shot; harmful components entering the deduster are substantially reduced; the problem that the recovered powder is hard to treat is overcome; and the apparatus is simple in structure and low in investment.

Description

technical field [0001] The invention relates to asphalt regeneration and mixing equipment, in particular to tail gas and waste powder processing equipment of the asphalt regeneration and mixing complete set of equipment. Background technique [0002] During the production process of plant-mixed asphalt regeneration equipment, waste powder (recycled powder) and recycled asphalt tail gas (containing harmful gases and particles) will be generated. In the current asphalt industry, the waste powder and tail gas are treated separately, and the structure of the treatment equipment is complicated and the cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a tail gas and waste powder comprehensive treatment equipment for asphalt regeneration and mixing complete equipment, which has a simple structure and low cost. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] ...
