Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details.
Concentration-type exhaust treatment system, including waste gas upgrading unit, waste gas burning unit, also includes as shown in Figure 1
Exhaust gas treatment unit, waste gas passes sequentially through waste gas upgrading unit, waste gas burning unit and exhaust gas treatment unit.Wherein waste gas concentrates
Unit includes passing sequentially through rotary zeolite enrichment facility 1, disengaging fan 2, the secondary heat exchanger 3 sealing pipeline and linking together
And exhaust fan 4, rotary zeolite enrichment facility 1 is also connected with the suction fan 5 for aerofluxus.Waste gas burning unit is burning dress
Putting 6, exhaust gas treatment unit is emission-control equipment 7, wherein 4, heat exchanger 8, burner 6, exhaust-gas treatment of exhaust fan
Device 7 is sequentially connected with, and the exhaust end of emission-control equipment 7 and a heat exchanger 8 connect, and a heat exchanger 8 is simultaneously with two
Secondary heat exchanger 3 connects, and the gas after process is expelled to air through the air vent of secondary heat exchanger 3.
Wherein, in the present embodiment, burner 6 is preferably heat accumulating type oxidation furnace, and emission-control equipment 7 is that oxidation catalyst is anti-
Answer device.
The rotating speed of described rotary zeolite enrichment facility is 1-6r/h.
During the work of this equipment, the sealed pipeline of waste gas enters in rotary zeolite enrichment facility 1, and rotary zeolite concentrates
