Embodiment 1

[0060] The asphalt fume concentration device provided by the invention is as figure 1 and figure 2 As shown, the device includes the first VOC input main pipeline (corresponding to VOC input main pipeline 1 in the figure), the second VOC input branch pipeline (corresponding to VOC input branch pipeline 2 in the figure), adsorption / desorption module 3, and output clean air Branch pipeline 4, output clean air main pipeline 5, desorption hot gas main pipeline 6, desorption hot gas branch pipeline 7, concentrated VOC branch pipeline 8, concentrated VOC main pipeline 9 and control system, etc. The control system is mainly responsible for adsorption and desorption , Cooling and other operations automation control logic realization.

[0061] Adsorption / desorption module 3 is the core device of the concentration system, mainly composed of VOC input valve 31, clean air output valve 32, desorption hot gas input valve 33, concentrated VOC output valve 34, adsorption material 35 and box...

Embodiment 2

[0069] Such as Figure 1 to Figure 4 As shown, this embodiment provides an asphalt fume concentration system, which includes the asphalt fume concentration device in Embodiment 1. The system mainly includes the first soot trapping device (corresponding to soot trapping device 1 in the figure), the second soot trapping device (corresponding to soot trapping device 2 in the figure), conveying pipeline 1, conveying pipeline 2, pretreatment system, The induced draft fan 3, the induced draft fan 2, the heat exchanger and the asphalt flue gas concentrator in embodiment 1, and the original burner, drying drum, dust collector, induced draft fan 1 and chimney of the asphalt mixing station, the heat exchanger is The newly added device between the dust collector and the induced draft fan 1 in the original dust removal system can make full use of the residual temperature of the dust removal flue gas to provide desorption hot gas for the concentration system. The heat exchanger has a self-...

Embodiment 3

[0076] Such as Figure 1 to Figure 5 As shown, this embodiment provides a method for concentrating bitumen flue gas, which is realized based on the concentration system in Embodiment 2, and specifically includes the following process.

[0077] Collect asphalt fumes escaped during the heating process of asphalt and heavy oil storage tanks, and transport the recovered asphalt fumes to the pretreatment system through the delivery pipeline 1 for pretreatment. The second smoke and dust collection device is responsible for collecting the asphalt fumes escaped during the mixing, storage and discharging of asphalt mixture, and transporting the recovered asphalt fumes to the pretreatment system through the conveying pipeline 2 for pretreatment.

[0078] The pretreatment system includes multi-level pretreatment measures. The asphalt flue gas entering the pretreatment system is firstly treated by a first-level pretreatment-oil pan centrifugal demisting treatment to remove most of the lar...

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...
