Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of waste gas treatment especially, relates to a waste gas deodorization device. BACKGROUND

[0002] Kitchen garbage is easy to ferment to produce waste gas in the treatment process, and these waste gases usually contain various organic compounds, sulfides, ammonia and other components. During the fermentation process, a series of by-products are produced by microbial metabolism, including carbon dioxide, water, ethanol, organic acids, volatile organic compounds and the like. The composition of these waste gases is complex and has a special odor. If not properly treated, it will adversely affect the environment and human health.

[0003] The existing patent number CN221385909U discloses a fermentation waste gas deodorization device, which comprises a fermentation tank, a filter box, a connecting pipe, an acid washing tank and a support frame. The bottom end of the filter box is welded and fixed to the top right side of the fermentation tank. The left end bottom of the filter box is fixedly provided with a connecting pipe on the top side. The right side top end of the connecting pipe is fixedly provided at the bottom center of the acid washing tank. The top end of the support frame is welded and fixed to the top side of the bottom end of the acid washing tank on all four sides. The device can quickly pour kitchen waste into the fermentation tank for further fermentation treatment, thereby reducing the harmfulness of kitchen waste. It is convenient to replace and improve efficiency. The device can further replace the gas to improve efficiency and reduce the harm of impurities in the gas to the environment.

[0004] In the prior art, the waste gas is injected into the acid washing tank through a circular pipe. However, when there is no waste gas spouted, the acid washing liquid will flow back into the filter box through the circular pipe, causing device failure. At the same time, when the waste gas is spouted, the bubbles formed by the waste gas in the acid washing liquid are too large, which prevents the waste gas from fully reacting with the acid washing liquid. The small particles and impurities in the waste gas cannot be removed, which also reduces the deodorization efficiency. SUMMARY

[0008] To solve the above technical problems, the utility model provides the following technical scheme:

[0009] A waste gas deodorization device, comprising:

[0010] The main unit comprises a deodorization tank, a fixed pipe is installed on the lower side surface of the deodorization tank, a gas inlet pipe is installed on one side of the fixed pipe, a gas outlet pipe is installed on the upper side surface of the deodorization tank, a liquid inlet pipe is installed on one side of the deodorization tank, a limiting groove is formed in the side surface of the fixed pipe, and a pollution discharge assembly is arranged in the limiting groove;

[0011] The deodorization unit comprises a gas inlet ring fixedly connected to the inner wall bottom of the deodorization tank, the gas inlet ring is in communication with the fixed pipe, a plurality of gas inlet holes are formed in the surface of the gas inlet ring, a support plate is fixedly connected to the inner wall surface of the gas inlet ring, a sleeve is fixedly connected to the inside of the support plate, a sliding rod is slidably connected to the inside of the sleeve, a movable cover plate is fixedly connected to the lower end of the sliding rod, a filter assembly is arranged at the upper end of the sliding rod, a circular fixed plate is slidably connected to the inner wall surface of the sleeve, and the circular fixed plate is fixedly connected with the sliding rod; and a spring is fixedly connected to the upper side surface of the circular fixed plate, and the upper end of the spring is fixedly connected with the inner wall surface of the sleeve.

[0013] As a preferred scheme of the waste gas deodorization device, the height dimension of the gas inlet ring is consistent with the height dimension of the filter pipe, the outer side surface of the scraper is slidably connected with the inner wall surface of the filter pipe, and the outer side surface of the movable cover plate is slidably connected with the inner wall surface of the gas inlet ring.

[0014] As a preferred scheme of the waste gas deodorization device, the exhaust assembly comprises an enclosed plate movably connected with the fixed pipe, a threaded sleeve is fixedly connected to one side of the enclosed plate, a threaded rod is threadedly connected to the inside of the threaded sleeve, two groups of side fixed plates are rotatably connected to the surface of the threaded rod, the side fixed plates are fixedly connected to the outer surface of the fixed pipe, the surface of the threaded sleeve is slidably connected with the inner wall surface of the limiting groove, and the other side of the fixed pipe is provided with a sliding outlet, and the inner wall surface of the sliding outlet is slidably connected with the surface of the enclosed plate.

[0017] The waste gas deodorization device has the following beneficial effects:

[0018] 1. When waste gas is discharged, it enters the inside of the fixed pipe through the air inlet pipe, and then the waste gas pushes the movable cover plate to move upwards in the inside of the air inlet ring. When the movable cover plate is attached to the supporting plate, the air inlet hole is exposed, so that the waste gas passes through the air inlet hole and then enters the inside of the acid-base solution. The waste gas is in the form of fine bubbles when it enters the acid-base solution, which increases the mixing rate. Meanwhile, the scraper fixedly connected with the sliding rod moves upwards in the inside of the filter pipe, so that the waste gas can be discharged through the filter hole and further filtered. When the waste gas stops discharging, the circular fixed plate is pushed downwards by the elastic force of the spring, and the sliding rod is driven to move downwards. The movable cover plate and the scraper fixedly connected with the sliding rod move downwards at the same time, so as to clean the inner wall surface of the movable cover plate and the filter pipe. The movable cover plate is tightly attached to the positioning ring, so as to block the fixed pipe and the air outlet pipe. This not only prevents the acid-base solution from flowing back into the inside of the fixed pipe, but also makes the waste gas form fine bubbles, which improves the reaction effect with the acid-base solution and further improves the deodorization efficiency.

[0019] 2. By rotating the threaded rod in the inside of the side fixed plate, the threaded sleeve threadedly connected with the threaded rod drives the enclosed plate to move in the inside of the fixed pipe, so that the enclosed plate moves out of the sliding outlet, and the acid solution and impurities accumulated in the inside of the fixed pipe can be discharged.
