Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, there is provided a kind of waste gas recovery processing meanss, including storage
Deposit case 4, cooler 9 and the adsorption box 15 being connected with cooler 9；Storage bin 4 bottom is provided with aerator 5, and storage bin 4 side wall is even
It is connected to the air inlet pipe 1 for inputting waste gas, air inlet pipe 1 is provided with heat exchanger 3 and blower fan 2, and aerator 5 is installed on and extends to storage
Deposit in the air inlet pipe 1 of case 4 bottom；It is provided with refrigeration coil 6, cooler 9 is connected with adsorption box 15 by conduit 13 in cooler 9；
Conduit 13 is provided with micro-pressure-difference transmitter 12, is provided with rock wool layer 14 and active carbon layer 18 in adsorption box 15, and bottom is provided with and extends to
Outside exhaustor 11, exhaustor 11 is provided with valve.
Optimal enforcement example of the present utility model, as shown in Fig. 2 refrigeration coil 6 is the inside and outside double-deck spiral coil；Chill plate
Pipe 6 includes internal coiling coil pipe 61 and is located at the internal coiling coil pipe 61 radial outside external spiral coaxially connected with internal coiling coil pipe 61
Disk 62；Internal coiling coil pipe 61 is connected in the axial direction with external spiral coil pipe 62 one end, the other end in the axial direction respectively with external refrigeration
