Description
Technical Field
[0001] The invention relates to the field of waste gas treatment, and in particular to a black soldier fly breeding waste gas purification system. Background Art
[0002] During the breeding process of black soldier flies, the metabolism of materials and organisms will emit odors. If the odors are discharged directly without treatment, it is easy to pollute the environment. At present, negative pressure ventilation centralized circulation biological deodorization technology is generally used. The waste gas from black soldier fly breeding and composting is generally collected by negative pressure ventilation and introduced into the deodorization system for centralized treatment. The small amount of residual waste gas in the breeding workshop and composting workshop is masked by spraying deodorants.
[0003] However, in actual use, it was found that when the negative pressure exhaust fan transports the airflow to the deodorization system for treatment, since the traditional deodorization system only uses activated carbon adsorption plates for adsorption and deodorization, this will cause the airflow to remain in the deodorization system for a shorter time, and it is difficult to be fully absorbed by the activated carbon adsorption plates. For this reason, we have made improvements and proposed a black soldier fly breeding waste gas purification system. Summary of the invention
[0004] The object of the present invention is to provide a black soldier fly breeding waste gas purification system, which prolongs the retention time of the airflow in the deodorization system and sets a multi-stage deodorization mechanism to make the deodorization reaction more complete and thus achieve an efficient deodorization effect.
[0005] In order to achieve the above-mentioned invention object, the present invention provides a black soldier fly breeding waste gas purification system, including a purifier housing, wherein the top and bottom of one side of the purifier housing are respectively provided with an air inlet and an air outlet, wherein the air inlet and the air outlet form an air flow channel through a fan installed on the top wall of the purifier housing, and the fan can extract the waste gas through the air inlet when it is working, and further comprising: The split filter component is connected to the bottom of the fan to perform adsorption and filtration on the air flow sucked in from the air inlet; A deodorizing pipe group, connected to the bottom of the split flow filtering component, is used to deodorize and decompose the airflow; The photocatalytic adsorption component includes a drainage pipe fixedly connected to the air outlet end of the deodorizing pipe group, one end of the drainage pipe is connected to an adsorption box, the bottom of the adsorption box is fixedly connected to an output pipe, the bottom of the output pipe is connected to a diffusion cover, and the diffusion cover cooperates with the air outlet; An ultraviolet lamp is arranged in the middle of the adsorption box, and a reflector is also arranged on the top of the adsorption box. The side walls of the adsorption box are respectively inserted with a primary activated carbon plate and a secondary activated carbon plate from top to bottom. The surface of the primary activated carbon plate is coated with a photocatalyst. The reflector can focus the ultraviolet lamp so that the light of the ultraviolet lamp can shine on the primary activated carbon plate to the greatest extent.
[0006] As a preferred technical solution of the present invention, the diversion filter component includes a filter tank, a clamping tube is arranged in the middle of the filter tank, and a plurality of stacked activated carbon filter covers are clamped on the side wall of the clamping tube. A diversion hole is opened on the side wall of the clamping tube, and the diversion hole is connected to the top layer of activated carbon filter cover. The exhaust gas is dispersed into the activated carbon filter covers at different positions through the diversion holes in the clamping tube.
[0007] As a preferred technical solution of the present invention, the activated carbon filter cover is funnel-shaped, with a gap between the two activated carbon filter covers and abutting and sealing at the edges to allow the airflow to flow in the gap between the activated carbon filter covers. After being filtered by the activated carbon filter covers, the exhaust gas can move downward in sequence and then be filtered step by step. The gaps between the activated carbon filter covers facilitate the intersection and dispersion of the exhaust gas.
[0008] As a preferred technical solution of the present invention, the filter tank includes an upper tank and a lower tank, and the upper tank and the lower tank are fixedly connected by bolts. The upper tank and the lower tank are respectively provided with pipe adapters for connecting the deodorizing pipe group and the fan, and the pipe adapters facilitate the installation of the filter tank. The upper tank and the lower tank are connected by bolts, and the activated carbon filter cover can be disassembled and replaced.
[0009] As a preferred technical solution of the present invention, the deodorizing pipe group includes an inclined conduit connected to the diversion filter component and a delivery pipe connected to the bottom of the inclined conduit; Among them, the delivery pipe includes a reciprocatingly arranged extension pipe and a liquid storage ball at the bottom for storing deodorant. The top of the liquid storage ball is connected to an exhaust pipe, and the exhaust pipe is fixedly connected to the drainage pipe. The bottom of the exhaust pipe is open and threadedly connected with a sealing cover. The sealing cover can be opened to replenish the deodorant to the liquid storage ball through the exhaust pipe.
[0010] As a preferred technical solution of the present invention, the deodorizing pipe group also includes a deodorizing chain arranged in the conveying pipe. When the airflow is conveyed in the inclined conduit, the deodorizing chain can be pushed to move in the conveying pipe. The circulating movement of the deodorizing chain can deodorize the waste gas in the conveying pipe. When the deodorant is filled in the liquid storage ball, it reaches at least two-thirds of the liquid storage ball, so that the deodorizing chain can absorb the deodorant when moving.
[0011] As a preferred technical solution of the present invention, the deodorizing chain comprises a soft steel wire rope, to which a plurality of adsorption balls and piston balls are connected, and the soft steel wire rope can be deformed, thereby facilitating movement in the conveying pipe.
[0012] As a preferred technical solution of the present invention, the side wall of the adsorption ball is provided with a plurality of adsorption holes, and the middle part of the adsorption ball is filled with a water-absorbing sponge. The water-absorbing sponge can absorb the deodorant in the liquid storage ball when passing through the liquid storage ball, and the adsorption holes facilitate the water-absorbing sponge to absorb the deodorant.
[0013] As a preferred technical solution of the present invention, the piston ball is a hollow rubber ball, and there is a gap between the piston ball and the delivery tube. The hollow rubber ball is used to reduce the weight and facilitate airflow push. The gap-fitting piston ball and the delivery tube will not cause jamming while ensuring that most of the airflow can be pushed. At the same time, the liquid will not be squeezed out by the piston ball, so that the liquid remains in the liquid storage ball.
[0014] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of the present invention: 1. Through the arrangement of the air inlet, air outlet, fan, shunt filter component, deodorizing pipe group and photocatalytic adsorption component, the fan sucks the exhaust gas through the shunt filter component for filtration. After the airflow enters the filter tank, it enters the activated carbon filter cover through the shunt holes on the clamping tube. It is gradually filtered and adsorbed from top to bottom in the activated carbon filter cover. Moreover, it can be dispersed and intersected in the two activated carbon filter covers and then filtered and adsorbed downward again. The airflow after filtration and adsorption is then transported to the deodorizing pipe group and the photocatalytic adsorption component for deodorization, filtration and adsorption operations, thereby ensuring the purification quality; 2. Through the setting of the deodorizing pipe group, the airflow is introduced into the delivery pipe from the inclined conduit and flows in the clockwise direction. During the flow, it will push the piston ball to move, thereby providing power for the entire deodorizing chain. When the deodorizing chain moves, the airflow can be gradually delivered to the liquid storage ball. When the airflow passes through the liquid storage ball, it is further decomposed and purified by the deodorant in the liquid storage ball. At the same time, when the adsorption ball passes through the liquid storage ball, it will carry the deodorant in the liquid storage ball to flow, so that the deodorant is volatilized and deodorized in the delivery pipe. The sealing cover on the top of the exhaust pipe can also be opened to replenish the deodorant to the liquid storage ball. 3. Through the setting of the photocatalytic adsorption component, the airflow is further adsorbed and purified when passing through the primary activated carbon plate and the secondary activated carbon plate in the adsorption box, ensuring that the final exhausted air is clean and dry. At the same time, the ultraviolet lamp irradiates the photocatalyst on the surface of the primary activated carbon plate to further decompose organic matter and some inorganic matter, reducing odor and stench in the air. The ultraviolet lamp achieves a focusing effect under the action of the reflector to ensure sufficient light. BRIEF DESCRIPTION OF THE DRAWINGS

A reflector 46 is also arranged on the top of the adsorption box 42. The side walls of the adsorption box 42 are respectively inserted with a primary activated carbon board 47 and a secondary activated carbon board 48 from top to bottom. The surface of the primary activated carbon board 47 is coated with a photocatalyst. The reflector 46 can focus the ultraviolet lamp 45 so that the light of the ultraviolet lamp 45 is irradiated to the primary activated carbon board 47 to the greatest extent. The primary activated carbon board 47 and the secondary activated carbon board 48 are installed on the adsorption box 42 by plugging, which is convenient for disassembly and replacement.
[0019] As a preferred embodiment, on the basis of the above-mentioned method, further, the diversion filter component 20 includes a filter tank 21, a clamping tube 22 is arranged in the middle of the filter tank 21, and a plurality of stacked activated carbon filter covers 23 are clamped on the side wall of the clamping tube 22, and a diversion hole 24 is opened on the side wall of the clamping tube 22, and the diversion hole 24 is connected with the top layer of activated carbon filter cover 23, and the exhaust gas passes through the diversion hole 24 in the clamping tube 22 and is dispersed into the activated carbon filter covers 23 at different positions, and the activated carbon filter cover 23 is assembled on the clamping tube 22 in a clamping manner for easy disassembly and replacement. Specifically, the outer wall of the clamping tube 22 has a clamping strip, and the inner wall of the activated carbon filter cover 23 has a clamping groove, and the activated carbon filter cover 23 is clamped on the clamping strip through the clamping groove to form an assembly, and the clamping tube 22 has a plurality of diversion holes 24, which is convenient for conveying the waste to the activated carbon filter covers 23 at different positions, and the airflow can flow and filter on the activated carbon filter cover 23 from top to bottom in sequence.
[0020] The activated carbon filter cover 23 is funnel-shaped, with a gap 25 between the two activated carbon filter covers 23 and abutting and sealing at the edge to allow airflow to flow in the gap 25 of the activated carbon filter cover 23. After being filtered by the activated carbon filter cover 23, the exhaust gas can move downward in sequence and then be filtered step by step. There is a gap between the activated carbon filter covers 23 to facilitate the intersection and dispersion of the exhaust gas. Specifically, the edge of the activated carbon filter cover 23 has a protrusion extending downward, which can be snapped onto the top of the next activated carbon filter cover 23 to fit.
[0021] The filter tank 21 includes an upper tank 211 and a lower tank 212, which are fixedly connected by bolts. The upper tank 211 and the lower tank 212 are respectively provided with pipe adapters 213 connecting the deodorizing pipe group 30 and the fan 13. The pipe adapter 213 facilitates the installation of the filter tank 21. The upper tank 211 and the lower tank 212 are connected by bolts, and the activated carbon filter cover 23 can be disassembled and replaced. Bolts are inserted into the edge of the lower tank 212, and threaded holes compatible with the bolts are opened at the edge of the upper tank 211. The bolts are threadedly connected to the threaded holes to fix the upper tank 211 and the lower tank 212.
[0022] As a preferred embodiment, based on the above-mentioned method, further, the deodorizing pipe group 30 includes an inclined conduit 31 connected to the diversion filter component 20 and a delivery pipe 32 connected to the bottom of the inclined conduit 31; Among them, the delivery pipe 32 includes a reciprocatingly arranged extension pipe 321 and a liquid storage ball 322 at the bottom for storing deodorant. The liquid storage ball 322 is located at the top of the diffusion cover 44, and the diffusion cover 44 forms a support and fixation for the liquid storage ball 322. The top of the liquid storage ball 322 is connected to an exhaust pipe 323, and the exhaust pipe 323 is fixedly connected to the drainage pipe 41. The bottom of the exhaust pipe 323 is open and threadedly connected with a sealing cover 324. The sealing cover 324 is opened to replenish the deodorant to the liquid storage ball 322 through the exhaust pipe 323. The extension pipe 321 is arranged in a reciprocating folding manner, which can increase the time for the airflow to flow in the extension pipe 321, so that the volatilization and deodorization effect of the deodorant can be more sufficient.
[0023] The deodorizing pipe group 30 also includes a deodorizing chain 33 arranged in the conveying pipe 32. When the air flow is conveyed in the inclined conduit 31, the deodorizing chain 33 can be pushed to move in the conveying pipe 32. The circulating movement of the deodorizing chain 33 can deodorize the exhaust gas in the conveying pipe 32. When the deodorant is filled in the liquid storage ball 322, it should reach at least two-thirds of the liquid storage ball 322, so that the deodorizing chain 33 can absorb the deodorant when moving.
[0024] The deodorizing chain 33 includes a soft steel wire rope 331, to which a plurality of adsorption balls 332 and piston balls 333 are connected. The soft steel wire rope 331 can be deformed to facilitate movement in the conveying pipe 32. The adsorption balls 332 and the piston balls 333 can be arranged alternately, or a piston ball 333 can be set between two or three adsorption balls 332, so as to ensure that the airflow can effectively push the piston ball 333 to move.
[0025] The side wall of the adsorption ball 332 is provided with a plurality of adsorption holes 334, and the middle part of the adsorption ball 332 is filled with a water-absorbing sponge 335. The water-absorbing sponge 335 can absorb the deodorant in the liquid storage ball 322 when passing through the liquid storage ball 322. The adsorption holes 334 facilitate the water-absorbing sponge 335 to absorb the deodorant. After absorbing enough deodorant, the water-absorbing sponge 335 will form a dripping effect due to gravity when moving, so that the deodorant drips into the extension tube 321 for volatilization and deodorization.
[0026] The piston ball 333 is a hollow rubber ball, and there is a gap between the piston ball 333 and the delivery tube 32. The hollow rubber ball is used to reduce the weight and facilitate airflow propulsion. The piston ball 333 and the delivery tube 32 with a gap fit will not cause jamming while ensuring that most of the airflow can be pushed. At the same time, the liquid will not be squeezed out by the piston ball 333, so that the liquid remains in the liquid storage ball 322.
[0027] Specifically, when the black soldier fly breeding waste gas purification system is working / in use: the fan 13 works to suck the waste gas into the diversion filter component 20 for filtration. Specifically, after the airflow enters the filter tank 21, it enters the activated carbon filter cover 23 through the diversion holes 24 on the clamping tube 22, and is gradually filtered and adsorbed from top to bottom in the activated carbon filter cover 23. Moreover, the two activated carbon filter covers 23 can be dispersed and intersected and then filtered and adsorbed downward again. The airflow after filtration and adsorption is then transported to the deodorization pipe group 30. The airflow is introduced into the delivery pipe 32 by the inclined conduit 31 and flows in the clockwise direction. During the flow, it will push the piston ball 333 to move, thereby providing power for the entire deodorization chain 33. When the deodorization chain 33 moves, the airflow can be gradually transported to the liquid storage ball 322. When the airflow passes through the liquid storage ball 322, it is further decomposed by the deodorant in the liquid storage ball 322. Purification, at the same time, when the adsorption ball 332 passes through the liquid storage ball 322, the absorbent sponge 335 absorbs the deodorant through the adsorption hole 334, and at this time, the deodorant in the liquid storage ball 322 will flow, so that the deodorant will volatilize and deodorize in the delivery pipe 32, and the sealing cover 324 on the top of the exhaust pipe 323 can also be opened to replenish the deodorant to the liquid storage ball 322. After the airflow enters the exhaust pipe 323, it is transported to the adsorption box 42 through the drainage pipe 41. When the airflow passes through the primary activated carbon plate 47 and the secondary activated carbon plate 48 in the adsorption box 42, it is further adsorbed and purified to ensure that the final discharged air is clean and dry. At the same time, the ultraviolet lamp 45 irradiates the photocatalyst on the surface of the primary activated carbon plate 47 to further decompose organic matter and some inorganic matter, reduce the odor and stench in the air, and the ultraviolet lamp 45 achieves a focusing effect under the action of the reflector 46 to ensure sufficient illumination.
