Abstract

The invention discloses an asphalt flue gas concentration device, system and method.The device comprises an adsorption / desorption module, the adsorption / desorption module comprises a box body and an adsorption material arranged in the box body, and the box body is connected with a VOC input valve, a clean air output valve, a desorption hot gas input valve and a concentrated VOC output valve; the VOC input valve and the concentrated VOC output valve are located on one side of the adsorption material, and the clean air output valve and the desorption hot air input valve are located on the other side of the adsorption material; and according to the designed concentration device, the operation processes of adsorption, desorption, cooling and the like can be automatically switched through opening and closing of the valves, large-air-volume low-concentration asphalt flue gas can be converted into small-air-volume high-concentration flue gas, and the influence on a combustion-drying-dust removal system is reduced.

Description

technical field

[0001] The invention relates to the technical field of asphalt mixture mixing equipment, in particular to an asphalt fume concentration device, system and method. Background technique

[0002] Asphalt mixing equipment is a complete set of equipment that mixes the mixture of coarse aggregate, fine aggregate, powder and asphalt after heating and drying at a certain temperature according to the design ratio to form a uniform mixture. It has been widely used in highways, urban roads, Infrastructure such as docks and airports are under construction. With the continuous development of society, environmental problems have become increasingly prominent. The country has paid more and more attention to environmental protection. The issue of smoke emission has received more and more attention. The main components include asphalt smoke oil droplets, gaseous carcinogenic odor VOC and dust, smoke particles, etc. In order to prevent asphalt smoke from endangering human hea...
