To achieve the above object, the utility model provides following technical scheme：A kind of soil greenhouse with filtering function
Gas sample static chamber, including casing, the inner cavity top left and right sides of the casing are mounted on ultraviolet germicidal lamp, the case
The top of body is from left to right sequentially installed with gas production syringe, triple valve and collection airbag, the right side of the gas production syringe and triple valve
Pass on left pipeline connection, the right side of the triple valve is connected with the left side of collection airbag, and the bottom of the triple valve is provided with
Connecting tube, the bottom of the connecting tube extend to the inner cavity top of casing at the top of casing, and the bottom of the connecting tube connects
Cartridge filter is connected to, the inner chamber of the cartridge filter is sequentially installed with fibrous filter layer, filtering cotton core and active carbon layer, institute from top to bottom
The bottom for stating cartridge filter is connected with discharge, and the outer wall of the discharge is uniformly provided with through hole.
Preferably, the fibrous filter layer is polyethylene terephthalate filter layer.
Preferably, it is symmetrically installed with fan at left and right sides of the inner chamber of the casing.
Preferably, the discharge and connecting tube are connected through a screw thread with cartridge filter.
Compared with prior art, the beneficial effects of the utility model are：One kind that the utility model proposes has filtering work(
The Soil Trace Gases sampling static chamber of energy, when carrying out greenhouse gases collection, can be good at clearly by ultraviolet germicidal lamp
Except the bacterium in gas in casing, by the fibrous filter layer in cartridge filter, filtering cotton core and active carbon layer, sky can be filtered out
Dust, impurity and peculiar smell in gas so that the greenhouse gases sample cleanup gathered is pollution-free, saves the later stage to gathering gas
Treatment and purification process, save man power and material, improve the accuracy of detection, the through hole that the outer wall of discharge is set can
Ensure the uniformity and representativeness of gas, the utility model is easy to use, practical.
Brief description of the drawings
