Technical Field

[0001] The present application relates to the field of odor treatment, and in particular, to an odor collection and treatment device. Background Art

[0002] Ammonia, hydrogen sulfide and other odors are easily generated during the treatment of food waste, kitchen waste, sludge drying, etc., especially some closed or semi-closed garbage pretreatment equipment produces a large amount of odor during the production process.

[0043] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0044] Reference Figure 1-4, an odor collection and treatment device, including an odor collection area 1, a catalytic area 2, a deodorization area 3, a pressure monitoring sensor 4, a variable frequency axial flow fan 5, and a controller 6; the output end of the odor collection area 1 is connected with an air pipe, and the catalytic area 2 and the deodorization area 3 are connected to the odor collection area 1 through the air pipe, and the pressure monitoring sensor 4 and the variable frequency axial flow fan 5 are arranged on the air pipe and located between the catalytic area 2 and the odor collection area 1.

The catalytic area 2, the deodorization area 3, the pressure monitoring sensor 4, and the variable frequency axial flow fan 5 are all arranged on the branch air pipe 8. The pressure value P monitored by the corresponding pressure monitoring sensor 4 on each branch air pipe 8 assigns the upper and lower limits of the pressure of the odor collection area 1 that is prone to generate or overflow odor as PA and PB respectively (PA and PB are both less than 0, and PA>PB). When the pressure monitoring sensor 4 detects that the corresponding pressure value P on each air distribution pipe 8 is greater than PA, that is, P>PA>PB, the variable frequency axial flow fan 5 controls its impeller speed through frequency conversion, so that the corresponding pressure value P on each air distribution pipe 8 is between PA and PB, that is, PB<P<PA; when the pressure monitoring sensor 4 detects that the corresponding pressure value P on each air distribution pipe 8 is less than PB, that is, P<PB, the variable frequency axial flow fan 5 controls its impeller speed through frequency conversion, so that the corresponding pressure value P on each air distribution pipe 8 is between PA and PB, that is, PB<P<PA.
