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 recovering device, including seal box
Body 13, cooler 4 and the air accumulator 1 being connected with cooler 4；Pass through return duct 18 even between air accumulator 1 and seal case 13
Logical, return duct 18 connects air inlet pipe 19 and exhaustor 10 respectively, and air inlet pipe 19 is provided with intake valve, the row of being provided with exhaustor 10
Air valve 21, return duct 18 is additionally provided with wasted nickel catalyst instrument 2；It is sequentially provided with active carbon layer 15 and rock wool 11, rock in seal case 13
The top of cotton 11 is provided with discharge 8, and discharge 8 is connected with cooler 4 by runner pipe 9；It is provided with chill plate in cooler 4
Pipe 5, cooler 4 is connected with air accumulator 1 by connecting tube 3.
Optimal enforcement example of the present utility model, as shown in Fig. 2 discharge 8 is provided with escape pipe 17 and is arranged on escape pipe
On air outlet valve, and discharge 8 one end is communicated with pressure gauge 7；Refrigeration coil 5 is the inside and outside double-deck spiral coil；Refrigeration coil 5
