[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The purpose of the present invention is to provide a new type of energy-saving odor collection and treatment system specially used for aquaculture. The odor collection efficiency is high, and through a variety of filtering and treatment methods, the harmful components in the odor are decomposed and treated to the greatest extent, thereby improving the odor treatment efficiency, and achieving low energy consumption, low pollution, and high efficiency in collecting and treating the odor and waste gas generated by the farm.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 9As shown, the odor collection and treatment system for aquaculture provided by the embodiment of the present invention includes: an odor collection device and an odor treatment device, the odor collection device includes an air intake pipe 1, a guide channel 3 and an adsorption channel 4 connected in sequence, and an axial flow fan 1-1 (such as Figure 3 As shown), the guide channel 3 is a gradually expanding semi-conical channel, the end connected to the intake pipe 1 has a small opening, and the end connected to the adsorption channel 4 has a large opening, and a plurality of active adsorption plates 4-1 are arranged in the adsorption channel 4; Figure 3 The blade shape of the axial flow fan 1-1 and the installation structure of the filter plate 2;

[0029] The air inlet of the guide channel 1 is a semi-conical structure, which can make the gas flow angle close to 90°, increase the total pressure of the fan 1, and improve the working efficiency; on the other hand, it can also increase the gas flow rate; the air inlet of the guide channel 1 is provided with a filter plate 2, and the filter plate 2 is used to filter solid impurities in the odor. As the first step of the equipment processing flow, the filter plate 2 mainly prevents solid impurities in the breeding house from entering the odor collection and treatment device to affect the working efficiency and service life of the equipment.

[0030] At the same time, the rotation speed of the axial flow fan 1-1 can also be adjusted according to the flow rate of the odor to be treated to ensure the treatment efficiency. The concentration of the odor can be measured according to the waste concentration detector. The rotation of the axial flow fan 1-1 generates negative pressure, so that the air (odor) in the closed breeding house flows toward the axial flow fan 1. Under the action of the slight negative pressure of the axial flow fan 1, the odor is sucked into the air intake pipe 1, and through the guide channel 3, the odor enters the adsorption channel 4 from the large end of the guide channel 3. After the adsorption of the active adsorption plate 4-1 in the adsorption channel 4, the pressure of the axial flow fan 1 is used to send the air (odor) into the odor treatment device, and the air (odor) is introduced into the air distribution cavity 7.

[0031] The active adsorption plate 4-1 is made of activated carbon fiber. A plurality of the active adsorption plates 4-1 are installed in parallel in the adsorption channel 4. On the one hand, the collected odor can be pre-treated and tiny solid particles such as dust can be adsorbed to prevent concentrated precipitation in the water collection layer and blockage of the drain pipe 8 below. On the other hand, the speed of the odor can be made uniform, which is convenient for further processing. After the odor passes through the adsorption plate 4-1 in the adsorption channel 4, it flows out from the square outlet of the adsorption channel 4. At the same time, the active adsorption plate 4-1 in the adsorption channel 4 is detachable. Figure 4 and Figure 5As shown, the adsorption channel 4 is provided with five pairs of straight tenons parallel to the inlet and outlet ends of the adsorbent by mortise and tenon joints. The active adsorption plate 4-1 is installed in the adsorption channel 4 by pulling and inserting. At the same time, a small fixed plate 4-2 with a hinge connection is installed at the connection between the straight tenon and the outer shell of the adsorbent, so as to realize the detachable, stable installation and quantity adjustment of the active adsorption plate 4-1 (up to 5 active adsorption plates). The dense small holes and uneven surface on the active adsorption plate 4-1 provide favorable conditions for the absorption and treatment of impurities. The number of active adsorption plates 4-1 installed depends on the flow rate of the odor and the concentration of impurities. The number of adsorption plates can be adjusted in time according to the flow rate and concentration to maximize the economic benefits and efficiency. When the concentration is large enough, you can choose to increase the active adsorption plate to improve the effect of rough treatment. At the same time, if the concentration of solid impurities in the odor is very low, you can choose to remove the active adsorption plate to increase the flow area and improve the collection efficiency.

[0032] The odor treatment device is installed on the outer edge of the wall of the breeding shed by surrounding a square shell with an outer layer. The odor treatment device includes an odor treatment box 18 and an air distribution cavity 7, a water collection mechanism, a spray device 13, a biological layer 14, and a carbon removal and demisting layer 15 arranged in the odor treatment box 18. The air inlet of the air distribution cavity 7 is connected to the adsorption channel 4. The water collection mechanism includes a water baffle 11, a water receiving trough 10, a support column 9, and a drain pipe 8. The water baffle 11 is fixed on the side wall of the odor treatment box 18. An opening is arranged in the middle of the water baffle 11. The water receiving trough 10 is arranged directly below the opening. The support column 9 is arranged below the water receiving trough 10, one end of which is connected to the water receiving trough 10, and the other end is connected to the odor treatment box 1 8 is used to support the water receiving trough 10; the bottom of the water receiving trough 10 is connected to a drain pipe 8, and the drain pipe 8 passes through the bottom of the odor treatment box 18; the spray device 13 is arranged just above the water baffle 11, and the spray device 13 is provided with a plurality of nozzles for spraying deodorizing liquid downward; the biological layer 14 is arranged above the spray device 13, and the biological layer 14 includes microorganisms fixedly attached to the surface of the porous medium filler, which is used to degrade odor by microorganisms; a carbon removal and demisting layer 15 is arranged above the biological layer 14, and the carbon removal and demisting layer 15 is used to filter carbon dioxide and water in the odor; the top of the odor treatment box 18 is connected to an exhaust pipe 17, and the air inlet end of the exhaust pipe 17 is provided with a power fan 16.

[0033] An adsorption layer 12 is provided between the water retaining plate 11 and the spraying device 13. Figure 6 As shown, the adsorption layer 12 is provided with a plurality of ball structures, so that the odor encounters the ball carriers during the process of rising through the adsorption layer 12, and has sufficient contact time with the sprayed deodorant liquid to fully react.

[0034] Among them, the biological layer 14 mentioned in the present invention is composed of a sheet structure composed of a carbon filler (bamboo charcoal filler) and a volcanic rock mixed material, and a microbial community attached to the surface of the filler. The filler has strong plasticity, a porous surface, high water retention, good water permeability and air permeability. The porous surface has good compatibility with microorganisms, is conducive to the growth of a variety of microorganisms, can form a rich variety of biological communities, and effectively remove various odor components at the same time. The process is to use microorganisms fixedly attached to the surface of the porous medium filler to make the odor vent on the filler bed. Pollutants such as volatile organic compounds are adsorbed on the pore surface and consumed by the microorganisms in the pores. The metabolic life activities of the microorganisms convert harmful substances in the exhaust gas into simple inorganic substances and cytoplasm, and decompose them into CO2, H2O and neutral salts. Thereby achieving the purpose of purifying odor. Principle: Odor pollutants + O2 microbial cells -> CO2 + H2O. The pollutants that can be treated include benzene, toluene, xylene, alcohol, aldehyde, ketone, phenol, ester, tetraaminofuran, mercaptan, etc. In addition, it can also be used to treat ammonia, H2S, NO X And other inorganic gases.

[0035] The carbon removal and mist removal layer 15 is composed of a sheet structure composed of activated carbon and soda lime filled on the surface. The main raw materials of activated carbon are all organic materials rich in carbon, such as coal, wood, fruit shells, coconut shells, walnut shells, apricot shells, jujube shells, etc. These carbon-containing materials are converted into activated carbon by pyrolysis at high temperature and certain pressure in an activation furnace. During this activation process, a huge surface area and a complex pore structure are gradually formed, and the adsorption process is carried out in these pores and on the surface. Activated carbon is a hydrophobic adsorbent made by high-temperature carbonization and activation of a material mainly containing carbon as a raw material. Activated carbon contains a large number of micropores, has a huge surface area, and has many tiny pores, so it is easy to form capillary phenomena and absorb water. Soda lime is loose and porous, and is a mixture of calcium oxide, water, sodium hydroxide and potassium hydroxide. It is mainly used as a desiccant (where calcium oxide plays a drying role), and can be used to dry neutral gases such as oxygen, and can also be used to dry alkaline gases such as ammonia. It can also be used to absorb acidic gases such as carbon dioxide and sulfur dioxide. Under the joint treatment of the two, the carbon removal and mist removal layer 15 has the functions of carbon removal and mist removal.

[0036] The working principle of the odor treatment device is as follows: the collected odor enters the air distribution cavity 7, and under the action of the outlet side power fan 16 installed on the top, it passes through the adsorption layer 12 and flows upward. The deodorizing liquid is sprayed downward through the spray device 13 and flows into the adsorption layer 12. The ball structure on the adsorption layer 12 forms a vortex and flows downward, so that the odor is fully in contact with the spray deodorizing liquid during the upward process through the adsorption layer 12, and part of the odor is removed by the spray water washing deodorization principle (the spray deodorizing liquid uses FS composite biological enzyme aqueous solution. The advantages of this solution are that it is non-toxic, harmless, colorless and odorless, and has a strong decomposition ability. It is an ideal deodorizing liquid) and is treated once; the liquid after the first treatment is concentrated in the water receiving trough 10 of the water collection mechanism and passed into the residual liquid treatment area through the drainage pipe 8 below. The remaining gas passes upward through the biological layer 14, and uses the microorganisms fixed on the surface of the porous medium filler to degrade pollutants such as volatile organic compounds into simple organic matter during their metabolism, thereby achieving secondary treatment of odor. Finally, it passes through the carbon removal and mist removal layer 15 to control the carbon dioxide and water content and reduce the impact on subsequent biogas digesters. The treated gas is discharged through the upper exhaust pipe 17 for further treatment, and the residual liquid after the reaction is collected through the water collection layer and then discharged through the drain pipe 8. These reaction liquids can be treated as nutrient solution for agricultural production.

[0037] like Figure 7 As shown, the air outlet of the adsorption channel 4 is welded with an indoor mounting plate 5, and the indoor mounting plate 5 is used to fix the odor collection device on the indoor side of the wall of the breeding shed; Figure 8 As shown, the air inlet of the air distribution cavity 7 is welded with an outdoor mounting plate 6, which is used to fix the odor treatment device on the outdoor side of the breeding shed wall. The indoor mounting plate 5 and the outdoor mounting plate 6 are arranged opposite to each other, and there are ventilation holes in the middle, which are connected by ventilation pipes. The breeding shed wall is provided with holes for the ventilation pipes to pass through. The four right angles of the outer edges of the two mounting plates are fixedly connected to the breeding shed wall by expansion bolts, so as to realize the fixed installation of the entire system on the wall. Fig. 9 shown.

[0038] like Fig.10As shown, the system also includes a power supply device, which is a solar photovoltaic panel arranged on the outer surface of the odor treatment box 18. The power supply device can also adopt an energy coupling mechanism, and the energy coupling structure is composed of solar cells, thermoelectric cells, biogas tank power supply system, related circuits and pipelines, etc., and uses solar photovoltaic cells laid on the surface of the odor treatment box 18 to generate electricity, and uses thermoelectric cells to collect waste heat generated on the surface of photovoltaic cells and convert it into electrical energy to provide more energy output. Complementary use is made with biogas energy to solve the problem of comprehensive high energy consumption and high pollution. Install a set of energy coupling system, by installing solar photovoltaic cells, thermoelectric cells and other equipment, and using clean energy such as solar energy and chemical energy and recyclable energy to power the device, it is more energy-saving and environmentally friendly than general devices, and reduces energy consumption and operating costs.

[0039] The odor collection and treatment system for aquaculture provided by the present invention, firstly, in the odor collection device, an axial flow fan is matched with a gradually expanding guide channel, so that the collected odor can pass through the device more fully and evenly, thereby improving the odor collection efficiency; in addition, the air inlet of the guide channel is a semi-conical structure, which can make the flow angle of the gas close to 90°, increase the total pressure of the axial flow fan, and improve the working efficiency, and on the other hand, increase the flow rate of the gas, and a filter plate is provided to prevent solid impurities in the breeding house from entering the odor collection device to affect the working efficiency and service life of the equipment; secondly, In the odor treatment device, a spray device is provided to spray deodorant, and part of the odor is removed by the spray water washing deodorization principle. After that, the odor is further treated through the multi-layer treatment structure such as the biological layer, carbon removal and demisting layer, and the harmful components in the odor are decomposed and treated to the greatest extent, thereby improving the odor treatment efficiency; finally, the treated gas is discharged through the exhaust pipe, and the liquid after the reaction is collected through the drain pipe. These reaction liquids can be treated as nutrient solution for agricultural production, so as to achieve low energy consumption, low pollution, and high efficiency in collecting and treating the odor and waste gas generated by the farm. For the waste liquid generated after the odor reacts with chemical reagents, unlike the general odor collection and treatment device that directly discharges these secondary organisms into nature, this system can collect these waste liquids through the drain pipe as raw materials for products such as liquid fertilizers and nutrient solutions, thereby achieving the effect of protecting the environment and effectively utilizing resources.
