Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to a tail gas treatment device for fermenting organic fertilizer from livestock and poultry manure. Background Technique

[0002] The tail gas treatment device for fermenting organic fertilizer from livestock and poultry manure is a device specifically used for treating the tail gas generated during the fermentation process. By physical, chemical or biological methods, the harmful substances in the tail gas are converted into harmless substances, so as to achieve the purpose of purifying the tail gas. Generally, there are physical absorption method, chemical absorption method and ultraviolet photolysis method, etc. Among them, the physical absorption method utilizes the characteristics that the solubility of some components in the tail gas in the absorbent changes with pressure and temperature, and absorbs the harmful substances in the tail gas into the absorbent, so as to realize the purification of the tail gas. Common absorbents include water, acid, alkali, etc. This method is suitable for treating tail gas components with good water solubility, such as ammonia gas, etc. The ultraviolet photolysis method uses ultraviolet photolysis technology to decompose the harmful substances in the tail gas into harmless substances. However, when using the ultraviolet photolysis method, as the core component, the irradiation intensity of the ultraviolet lamp tube will decrease with the increase of the use time and needs to be replaced regularly. And in order to better oxidize and decompose VOCs, an excessive amount of ultraviolet lamps is usually used, which will cause a large amount of ozone to be generated. When replacing the ultraviolet lamp, ozone is harmful to the human body, especially erosive and damaging to the eyes, respiratory tract and lungs, and there are certain deficiencies. Content of the Utility Model

[0003] The utility model aims to solve the problems existing in the prior art or related technologies.

[0004] For this reason, the technical solution adopted by the utility model is: a tail gas treatment device for fermenting organic fertilizer from livestock and poultry manure, including a spray tower, a conveying component, an ultraviolet photolysis mechanism, an air inlet pipe, an exhaust component, an ozone leakage prevention component and an absorption tower. The spray tower includes a tower body arranged. The conveying component is arranged on the top of the spray tower. The ultraviolet photolysis mechanism includes a box body arranged on the right side of the conveying component, a first manual valve arranged on the left part of the box body, a second manual valve arranged on the right part of the box body and an ozone sensor arranged on the inner side of the box body. The air inlet pipe is arranged at the rear side of the box body. The exhaust component includes a suction pump arranged at the top end of the box body, a suction pipe arranged at the top end of the suction pump and fixed to the box body, a discharge pipe arranged at the top end of the suction pump and an electric valve arranged on the discharge pipe. The ozone leakage prevention component includes a fixing plate screwed to the air inlet pipe, a spring arranged at the rear side of the fixing plate and a rubber piston arranged at the rear side of the spring. The absorption tower is arranged on the right side of the ultraviolet photolysis mechanism.

[0005] Preferably, the spray tower further includes an exhaust gas inlet pipe disposed on the left side of the tower body, a circulation pipe disposed outside the tower body, a circulation pump disposed on the circulation pipe, and the circulation pipe is fixedly connected to the spray pipe.

[0006] Preferably, the conveying assembly includes a conveying pipe disposed on the top of the spray tower and a Roots blower disposed on the conveying pipe.

[0007] Preferably, the ultraviolet photolysis mechanism further includes a sealing cover screwed to the front end of the box body and an ultraviolet lamp disposed inside the box body.

[0008] Preferably, a third manual valve is disposed on the air inlet pipe, and a through hole is formed on the outer side of the air inlet pipe.

[0009] Preferably, a round hole is formed in the middle position of the rubber piston, and the rubber piston is of a hollow structure.

[0010] By adopting the above technical solutions, the beneficial effects obtained by the present utility model are as follows: By providing an air inlet pipe and an exhaust assembly, the gas inside the ultraviolet photolysis structure can be drained completely without affecting the use of the exhaust gas treatment device, so as to facilitate the replacement and maintenance of the ultraviolet photolysis mechanism. At the same time, by providing an ozone leakage prevention assembly, the ozone inside the ultraviolet photolysis mechanism can be prevented from leaking out. During use, the user can manually rotate and close the first manual valve and the second manual valve, then control the opening of the electric valve of the exhaust assembly, and at the same time control the operation of the suction pump. The operating suction pump can transport the gas inside the ultraviolet photolysis mechanism to the absorption tower through the suction pipe and the extraction pipe, and then air can be introduced through the air inlet pipe. During the exhaust process, the ozone sensor can detect the ozone content inside the ultraviolet photolysis mechanism in real time, so as to understand whether the gas inside the ultraviolet photolysis mechanism is completely drained. After draining, it is convenient for the user to replace or maintain the ultraviolet lamp. At the same time, when the air inlet pipe intakes air, due to the blockage of the rubber piston of the ozone leakage prevention assembly, the gas inside the ultraviolet photolysis mechanism cannot leak out. When the exhaust assembly pumps air, a certain negative pressure will be generated inside the box body. At this time, the rubber piston will move, and the through hole will be exposed during the movement, and air can enter, effectively avoiding the problem of ozone leakage caused by the entry of external air.

The sprayed water can contact the exhaust gas of the livestock and poultry manure fermented organic fertilizer to facilitate absorption.

[0028] Specifically, the conveying assembly 200 is arranged on the top of the spray tower 100. The conveying assembly 200 includes a conveying pipe 201 arranged on the top of the spray tower 100 and a Roots blower 202 arranged on the conveying pipe 201. During use, the Roots blower 202 can transport the sprayed exhaust gas into the ultraviolet photolysis mechanism 300 through the conveying pipe 201 for ultraviolet photolysis.

[0029] Specifically, the ultraviolet photolysis mechanism 300 includes a box body 301 arranged on the right side of the conveying assembly 200, a first manual valve 303 arranged on the left part of the box body 301, a second manual valve 304 arranged on the right part of the box body 301, and an ozone sensor 305 arranged inside the box body 301. The ultraviolet photolysis mechanism 300 further includes a sealing cover 302 screwed to the front end of the box body 301 and an ultraviolet lamp 306 arranged inside the box body 301. During use, the first manual valve 303 and the second manual valve 304 can be manually rotated to close. After closing, the ultraviolet lamp 306 can be replaced. The ozone sensor 305 can detect the ozone content inside the ultraviolet photolysis mechanism 300 in real time to understand whether the gas inside the ultraviolet photolysis mechanism 300 is completely exhausted.

[0030] Specifically, the air inlet pipe 400 is arranged on the rear side of the box body 301.

[0032] Specifically, the absorption tower 700 is arranged on the right side of the ultraviolet photolysis mechanism 300. During use, the absorption tower 700 can spray the absorbent to absorb the tail gas.

[0033] Embodiment 2:

[0034] Referring to Figure 2 and Figure 3 , this is the second embodiment of the present utility model. The difference from the first embodiment is that it further includes an anti-ozone leakage component 600. The anti-ozone leakage component 600 includes a fixing plate 701 screwed to the air inlet pipe 400, a spring 702 arranged at the rear side of the fixing plate 701, and a rubber piston 703 arranged at the rear side of the spring 702. A circular hole 704 is opened at the middle position of the rubber piston 703, and the rubber piston 703 is of a hollow structure. Since the rubber piston 703 blocks the through hole 602 on the air inlet pipe 400, the gas inside the ultraviolet photolysis mechanism 300 cannot leak out.

The operating suction pump 501 can transport the gas in the ultraviolet photolysis mechanism 300 to the absorption tower 700 through the suction pipe 502 and the extraction pipe 503. Then, air can be introduced through the air inlet pipe 400. During the exhaust process, the ozone sensor 305 can detect the ozone content in the ultraviolet photolysis mechanism 300 in real time to understand whether the gas in the ultraviolet photolysis mechanism 300 is completely exhausted. After exhaustion, it is convenient for the user to replace or repair the ultraviolet lamp 306. At the same time, when the air inlet pipe 400 intakes air, due to the blockage of the rubber piston 703 of the anti-ozone leakage component 600, the gas inside the ultraviolet photolysis mechanism 300 cannot leak out. When the exhaust component 500 pumps air, a certain negative pressure will be generated in the box body 301. At this time, the rubber piston 703 will move, and the through hole 602 will be exposed during the movement, so that air can enter through the through hole 602, effectively avoiding the problem of ozone leakage caused by the entry of external air.
