Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, in particular to an integrated device for treating malodorous waste gas. Background Art

[0002] With the acceleration of the urbanization process, the generation of domestic garbage, especially kitchen waste, has increased sharply, posing severe challenges to urban management and environmental protection. Due to its high water content and perishable characteristics, kitchen waste will produce a large amount of malodorous gas during the stacking process, which not only affects the living quality of surrounding residents but also may become a breeding ground for germs, mosquitoes and flies. In severe cases, it will pollute the air and water sources. Traditional garbage treatment methods often focus on the collection and transportation of garbage, lacking effective on-site treatment means, especially the effective control and treatment of malodorous waste gas, which has become a major bottleneck in current urban environmental sanitation treatment. Content of the Utility Model

[0003] In view of this, the utility model provides an integrated device for treating malodorous waste gas. Through the fixed separation component, the water and solid in the kitchen waste are separated. Then, the kitchen waste degradation component degrades the garbage. The culture solution inside the liquid storage tank is pumped by a water pump to spray the microorganisms in the garbage pool, promoting the degradation of the garbage by the microorganisms. The rotating stirring rod mixes the garbage to accelerate the degradation rate. The harmful gas inside the garbage pool is purified by the waste gas treatment component, effectively removing the harmful components in the gas and reducing the emission pollution.

[0004] To solve the above technical problems, the utility model provides an integrated device for treating malodorous waste gas, including a garbage pool, and a treatment mechanism for treating kitchen waste is arranged on the garbage pool. The treatment mechanism includes a solid-liquid separation component, a kitchen waste degradation component and a waste gas treatment component;

[0005] The solid-liquid separation component includes a filter screen disposed inside the garbage pool and a chute disposed at the top of the garbage pool. A sewage tank is provided below the filter screen. A sliding block is slidably disposed in the chute, and a harrow is connected to the sliding block; the food waste degradation component includes a water pump disposed at the top of the garbage pool and two fixed frames symmetrically disposed inside the garbage pool. A water supply pipe is provided on each fixed frame, and a number of high-pressure nozzles are provided on the water supply pipe; the waste gas treatment component includes a draft fan disposed at the top of the garbage pool and an adsorption tower disposed on one side of the garbage pool. The solid and liquid in the food waste are separated by the filter screen installed inside the garbage pool, and the solid waste accumulated on the filter screen is scraped off by the sliding block and the harrow and falls into the pool for subsequent treatment, effectively realizing the preliminary separation of water and solids in the garbage; then, the culture solution is pumped by the water pump at the top of the garbage pool to supply the water supply pipe disposed inside the garbage pool, and the garbage in the garbage pool is degraded by the nozzles; and the malodorous gas inside the garbage pool is extracted by the draft fan at the top of the garbage pool. These gases are concentrated through the connected exhaust pipe and gas collection hood, and then are introduced into the adsorption tower disposed on one side of the garbage pool through the air supply pipe for purification treatment. The inside of the adsorption tower is filled with activated carbon and other adsorption materials, which can effectively remove the harmful components in the gas and reduce the emission pollution.

[0006] A screw rod is provided in the chute. The sliding block is slidably disposed in the chute through the screw rod. The harrow is connected to the sliding block through a fixed frame. A driving motor is provided on one side of the chute. The end of the output shaft of the driving motor is connected to one end of the screw rod. The harrow is fixed through the fixed frame and moves with the sliding block. The screw rod is rotated by the driving motor.

[0007] A liquid storage tank is provided on one side of the water pump. The water pump is connected to the liquid storage tank through a liquid supply pipe. The output end of the water pump is connected to the water supply pipe through a high-pressure liquid delivery pipe. The water pump extracts the culture solution from the liquid storage tank and supplies it to the high-pressure nozzles fixed on the fixed frames on both sides inside the garbage pool through the high-pressure liquid delivery pipe. The water is sprayed by the nozzles to wash and moisten the garbage, promoting the biodegradation process.

[0008] An exhaust pipe is connected to the input end of the draft fan. A gas collection hood is connected to the end of the exhaust pipe. A gas supply pipe is connected between the output end of the draft fan and the input end of the adsorption tower. The malodorous gas generated is extracted by the draft fan at the top of the garbage pool. These gases are concentrated through the connected exhaust pipe and gas collection hood, and then are introduced into the adsorption tower disposed on one side of the garbage pool through the gas supply pipe for purification treatment.

[0009] The food waste degradation component further includes a speed reduction motor. The output end of the speed reduction motor is connected with a rotating shaft. The tail end of the rotating shaft is connected to the inner wall of the garbage pool through a bearing. A number of stirring rods are sleeved on the rotating shaft. The speed reduction motor drives the rotating shaft and the stirring rods sleeved thereon to rotate, stirring the garbage in the garbage pool, so that the garbage, microorganisms and culture solution are in full contact, and the degradation rate is accelerated.

[0010] An inlet, an outlet and an observation window are fixedly arranged on the pool wall of the garbage pool. The inlet is arranged on the front pool wall of the garbage pool, the observation window is arranged on the right pool wall of the garbage pool, and the outlet is arranged below the observation window.

The sliding groove at the top of the garbage pool is equipped with a sliding block and a harrow structure. Through the cooperation of the built-in screw rod and the driving motor, the sliding block moves along the sliding groove, and the harrow scrapes the solid garbage accumulated on the filter screen and falls into the pool for subsequent treatment, effectively realizing the separation of water and solids in the garbage.

[0013] 2. When the utility model is in use, the pumping machine installed on the top of the garbage pool pumps the culture solution from the liquid storage tank and supplies it to the high-pressure nozzles fixed on the fixed frames on both sides inside the garbage pool through the high-pressure infusion pipe.
