AI Technical Summary
The ventilation and ventilation system of the existing hazardous waste storage warehouse is difficult to effectively purify the waste gas, resulting in harmful gases polluting the outdoor air and it is difficult to avoid the risk of spontaneous combustion.
A ventilation structure including a blower, an exhaust connection pipe and a water tank is designed. The exhaust connection pipe is equipped with a spiral partition plate and a water washing liquid. The exhaust gas is fully contacted with the water washing liquid in the exhaust connection pipe and is partially twisted into the water. The intake pipe sucks in the outside air through a check valve.
The exhaust gas is effectively purified and the purified gas emissions are achieved, which avoids the pollution of harmful gases to the outdoor atmosphere, and can absorb external air into the room with a smaller air pressure.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hazardous waste treatment equipment, and relates to a ventilation structure for a hazardous waste storage bin. Background Art
[0002] Warehouses for temporarily storing hazardous waste need to be properly ventilated to avoid excessive concentration of harmful gases in the warehouse, which may affect the health of operators. In addition, it is also necessary to prevent spontaneous combustion of harmful gases volatilized from hazardous waste. Therefore, it is necessary to set up a ventilation and air exchange system in the hazardous waste storage warehouse. The ventilation and air exchange system should ensure that the exhaust gas can be preliminarily purified and filtered before being discharged outdoors to avoid polluting the environment. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a ventilation structure for a hazardous waste storage bin in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to realize the ventilation of the hazardous waste warehouse.
[0004] The purpose of the utility model can be achieved by the following technical solutions: A ventilation structure for a hazardous waste storage bin, characterized in that it includes a blower, an exhaust connection pipe, and a water tank. One end of the exhaust connection pipe is connected to the air outlet end of the blower, and the other end of the exhaust connection pipe is connected to the outdoor atmosphere. The water tank is filled with washing liquid. A rotating shaft is rotatably connected in the exhaust connection pipe. The rotating shaft is provided with spiral partition plates. The water level of the water tank is below the axis of the rotating shaft, and part of the partition plates is below the liquid level. An intake pipe is connected to the exhaust connection pipe, and a one-way valve allowing outside air to pass through the intake pipe is arranged in the intake pipe.
[0005] Further, a first belt pulley is fixedly arranged on the rotating shaft, and a second belt pulley is fixedly arranged on the impeller shaft of the blower. The first belt pulley and the second belt pulley are tractioned by a belt.
[0006] The main body of the blower is located indoors, the part of the exhaust connection pipe connected to the air outlet end of the blower is also located indoors, and the intake pipe is also located indoors. Under normal circumstances, the exhaust gas is discharged outdoors by the blower sucking indoor gas and sending it into the exhaust connection pipe. Since the exhaust connection pipe is divided into multiple chambers by the partition plates and the liquid level, only when the partition plates rotate can the gas be gradually discharged outdoors. Therefore, the exhaust gas can fully contact the washing liquid in the exhaust connection pipe, and part of it is drawn into the washing liquid. When the external exhaust gas stops, similarly, the blower can be reversed to send the outside air back into the room, and the air sent back into the room enters the room through the intake pipe.
[0007] This ventilation method can avoid the pollution of the outdoor atmosphere by harmful gases in the warehouse and can also suck outside air into the room with a relatively small air pressure. Description of the Drawings

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0013] like Figure 1 , Figure 2 and Figure 3 As shown, the ventilation structure of the hazardous waste storage bin includes a blower 1, an exhaust pipe 2 and a water tank 3, one end of the exhaust pipe 2 is connected to the air outlet of the blower 1, and the other end of the exhaust pipe 2 is connected to the outdoor atmosphere. The water tank 3 is filled with water washing liquid, and a rotating shaft is rotatably connected in the exhaust pipe 2, and a spiral partition plate 4 is provided on the rotating shaft. The page of the water tank 3 is located below the axis of the rotating shaft, and the partition plate part is located below the liquid surface. An air inlet pipe 5 is connected to the exhaust pipe 2, and a one-way valve 6 is provided in the air inlet pipe 5 to allow external air to pass through the air inlet pipe 5.
[0014] A pulley 1 is fixedly arranged on the rotating shaft, a pulley 2 is fixedly arranged on the impeller shaft of the blower 1, and a belt is used to pull the pulley 1 and the pulley 2.
[0015] The main body of the blower 1 is located indoors, the part of the exhaust pipe 2 connected to the air outlet end of the blower 1 is also located indoors, and the air inlet pipe 5 is also located indoors. Under normal circumstances, the exhaust gas is discharged through the blower 1 to absorb the indoor gas and send it into the exhaust pipe 2. Since the exhaust pipe 2 is divided into multiple chambers by the partition plate 4 and the liquid level, only when the partition plate 4 rotates can the gas be gradually discharged to the outside. Therefore, the exhaust gas can fully contact the washing liquid in the exhaust pipe 2, and part of it is twisted into the washing liquid. When the gas is stopped, similarly, the blower 1 is reversed to send the outside gas back to the room, and the air sent back to the room enters the room through the air inlet pipe 5.
[0016] This ventilation method can prevent harmful gases in the warehouse from polluting the outdoor atmosphere, and can also draw outside air into the room at a lower pressure.
[0017] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
