The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses odor detection instrument system of a garbage storage system.

Referring to fig. 1 and 3, the odor detecting instrument system of the trash storage system includes a trash storage 1, a detecting device 2, and a deodorizing device 4. The rubbish repository 1 is the cuboid space of inside vacuole formation, and 1 one side of rubbish repository is equipped with the gate 12 that supplies rubbish to advance the storehouse or go out of the storehouse, and one side of gate 12 is articulated with rubbish repository 1. The detection device 2 is fixed on the inner wall of the cavity 11 of the garbage storage warehouse 1 and is used for detecting odor gas at each point position of the garbage storage warehouse 1, the deodorization device 4 is communicated with the garbage storage warehouse 1, and the communication position of the ventilation pipeline 5 and the garbage storage warehouse 1 is provided with the gas exchange device 3. After detection device 2 detects the foul smell gas, gaseous exchange device 3 with the foul smell gas direction deodorizing device 4 that detects, deodorizing device 4 discharges after deodorizing, gaseous exchange device 3 direct to leading-in fresh air of rubbish repository 1 simultaneously.

Referring to fig. 2, the detecting device 2 includes eight detecting instruments 22 and a central control instrument 21, one detecting instrument 22 is fixed or embedded in the inner wall near the eight vertices of the waste storage warehouse 1, the central control instrument 21 is fixed on the outer wall of the side of the waste storage warehouse 1, and the detecting instruments 22 are all communicated with the central control instrument 21. The detector 22 sets a threshold value for detecting the odorous gas, and when the odorous gas in the vicinity of the detector 22 exceeds the set threshold value, the detector 22 transmits an electric signal to the central control apparatus 21, and the central control apparatus 21 controls the gas exchange device 3 to transmit the detected odorous gas to the deodorizing device 4.

The gas exchange device 3 comprises two fans 31 and eight one-way air intake valves 32, in this embodiment the eight one-way air intake valves 32 are fixed to the inner walls of the eight vertices of the waste storage 1, the air inlets of the one-way air intake valves 32 communicating with the chamber 11 of the waste storage 1. The air sucked into the chamber 11 of the waste storage container 1 through the one-way air intake valve 32 is diffused toward the area where the detection point of the detector 22 is located, and the concentration of the odorous gas in the vicinity of the detector 22 is reduced.

Referring to fig. 3, two corresponding side surfaces of the waste storage warehouse 1 are respectively communicated with a ventilation pipeline 5, and one ends of the two ventilation pipelines 5 far away from the waste storage warehouse 1 are both communicated with the deodorization device 4. A fan 31 is fixed at one end of the ventilation duct 5 close to the garbage storage warehouse 1, the fan 31 is electrically connected with the central controller, and the fan 31 is used for sucking odor gas in the garbage storage warehouse 1 into the ventilation duct 5. The connection between the waste storage 1 and the ventilation duct 5 is covered with a filter net 33 for limiting the waste to be sucked away by the fan 31.

In this embodiment, when any one of the four detectors 22 of the fan 31 on the same side detects that the odorous gas exceeds the set threshold, the central control device 21 controls the fan 31 to start, and the fan 31 opposite to the fan 31 is in a standby state. Until the odorous gas concentration is below the threshold, the operating fan 31 is turned off to save energy. In other embodiments, when any one of the eight detectors 22 detects that the odorous gas exceeds the threshold value, the central control apparatus 21 controls the two fans 31 to be simultaneously started, and when the odorous gas concentration is lower than the threshold value, the two fans 31 are turned off.

When the fan 31 rotates to suck the odor gas in the chamber 11 of the garbage storage 1 into the ventilation duct 5, the chamber 11 of the garbage storage 1 forms a negative pressure. The one-way inlet valve 32 opens automatically under negative pressure and air from outside the waste storage 1 enters the chamber 11 of the waste storage 1 through the one-way inlet valve 32 until the pressure in the chamber 11 of the waste storage 1 is balanced with the pressure outside the one-way inlet valve 32 closes.

The deodorizing device 4 includes a plurality of activated carbon adsorption frames 42 and a filtering box 41, in this embodiment, the activated carbon adsorption frames 42 are four air-permeable frame structures with activated carbon particles inside, and the activated carbon adsorption frames 42 are fixed in the filtering box 41 at equal intervals to divide the filtering box 41 into five closed filtering chambers 43. Two ventilation ducts 5 communicate in the same filter chamber 43 of filter box 41 one end, and the junction of two ventilation pipes and filter box 41 all is connected with check valve 51, and the restriction gets into deodorizing device 4's foul gas flows back in rubbish repository 1. An air outlet 44 is arranged on one side of the filtering box body 41 far away from the installation surface of the ventilation pipeline 5, and the air filtered by the four-layer activated carbon adsorption frame 42 is exhausted.

The implementation principle of the embodiment is as follows: when one of the detectors 22 in the waste storage 1 detects that the concentration of the odorous gas exceeds the threshold value, the central control unit 21 controls the fan 31 close to the detector to start, the fan 31 guides the odorous gas into the ventilation duct 5, and the odorous gas enters the deodorizing device 4 through the ventilation duct 5. The odor gas is filtered by the four-layer activated carbon adsorption frame 42 in the deodorizing device 4 to become clean air, and is discharged from the exhaust port 44. During the process of the odorous gas being drawn into the ventilation duct 5, a negative pressure is created inside the waste repository 1 forcing the one-way air inlet valve 32 to open and clean air enters the chamber 11 of the waste repository 1 through the one-way air inlet valve 32.

When the concentration of the odorous gas is lower than the set threshold value, the central control device 21 controls the fan 31 to be closed, and when the air pressure inside and outside the waste storage warehouse 1 is kept balanced, the one-way air inlet valve 32 is closed.

The above embodiments are not intended to limit the scope of the present application, and all equivalent changes in structure, shape and principle of the present application should be covered by the present application.
