Specific embodiment
The utility model is described in detail below according to attached drawing and preferred embodiment, the purpose of this utility model and effect will become
It must be more clearly understood that, below in conjunction with drawings and examples, the present invention will be further described in detail.It should be appreciated that herein
Described specific embodiment is only used to explain the utility model, is not used to limit the utility model.
As shown in Figure 1, a kind of bitumen concrete with adsorption filtration structure produces dust-extraction unit comprising spray chamber 1, spray
Pitch exhaust gas entrance 3 is set on the left of room 1, vapor air jet pipe 2 is set inside spray chamber 1, water tank 5 is arranged in 1 bottom of spray chamber,
Liquid separation layer 4 is arranged in 5 surface of water tank, and water return pipe 6 is arranged in 1 side wall of spray chamber, and the lower end of water return pipe 6 is connected to water tank 5；
Aspiration pump 7 is connected by pipeline at the top of spray chamber 1,7 right side pipeline of aspiration pump connects clarifier 8, the other end connection of clarifier 8
Drier 9, drier 9 are connected to the side wall of dust cleaning case 15 by pipeline, and the middle part of dust cleaning case 15 is adsorption chamber 10, and right side wall is set
Pollutant analysis instrument 12 is set, connection clean gas outlet 14 on the right side of pollutant analysis instrument 12, the 15 external gas in top of dust cleaning case is again
Circulation canal 13, the other end of gas recirculation passage 13 are connected to the top of spray chamber 1.
It can be discharged by setting pollutant analysis instrument 12 so that gas is up to standard, if exhaust gas is not up to standard, pass through gas
Body recirculation line enters in spray chamber circular treatment again.
Further, pivoting leaf 11 is arranged in the top of dust cleaning case 15, can reduce dedusting when carrying out rotary work
