Description

Technical Field

[0001] The present invention relates to the production of animal protein powder, and in particular to an energy-saving and environment-friendly complete set of animal protein processing equipment and process. Background Art

[0002] Animal hairs such as chicken feathers, duck feathers, goose feathers, pig hairs, cow hairs, and wool are also rich in protein and in principle also belong to the raw materials of animal protein powder. However, different from raw materials such as fish and shrimp waste and meat bones, it is difficult for animal hairs to obtain protein powder through cooking and drying. The large amount of these animal hairs discarded will cause certain environmental pollution.

[0003] As a high-molecular-weight protein, developing a device for decomposing animal hairs has become an urgent project to be overcome in the protein powder industry.

[0004] In addition, the production of animal protein powder generates a large amount of odor; directly discharging the odor into the atmosphere is more harmful to the environment. The prior art uses the methods of cooling and spray adsorption to settle the odor. This method only precipitates the odor into stinky water and only reduces the rapid diffusion of the odor, and it cannot actually eliminate the odor. Summary of the Invention

The spiral stirring paddle is arranged in the inner cylinder. The feeding port is used to receive the chemical agent and the materials output from the storage bin. The spiral stirring paddle is used to mix the chemical agent and the materials, decompose the materials into small molecular weight protein powder particles and water, and scrape the mixed or decomposed materials towards the discharging port of the cylinder body to separate the water, so as to complete the initial drying of chemical quality. A net-shaped liquid leakage bottom plate is arranged at the section of the inner cylinder located in the outer cylinder.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0047] Refer to Figure 1, in the first aspect of the embodiments provided by the present invention: an energy-saving and environmental-friendly complete animal protein processing equipment, including a crusher 110, a storage bin 120, a quality-changing machine 200, a press 310, a dryer 320, a cooler 330, a grinder 350 and a deodorization device 400. The crusher 110, the storage bin 120, the quality-changing machine 200, the press 310, the dryer 320, the cooler 330 and the grinder 350 are connected in series in sequence;

[0048] The crusher 110 is used for crushing materials and transporting the materials to the storage bin 120;

[0049] Refer to Figures 2 to 5 , the quality-changing machine 200 includes a cylinder body and a spiral agitator 240. Feed ports 221 and a blanking port 223 are respectively arranged at both ends of the cylinder body. The feed port 221 of the cylinder body is used for receiving chemical agents and the materials output from the storage bin 120. A double-wall sandwich cavity 211 is arranged on the peripheral wall of the cylinder body. The spiral agitator 240 is used for mixing the chemical agents and the materials, and for scraping the mixed or decomposed materials towards the blanking port of the cylinder body;

[0050] Refer to Figures 6 to 8 , the deodorization device 400 includes a burner, a first heat exchange tower 421, a first exhaust pipe 422, an externally wound coil, a first hot water tank 434 and a steam generation tank 436. The odors discharged from the quality-changing machine 200, the press 310 and the dryer 320 are introduced into the burner. The exhaust port of the burner is connected to the first heat exchange tower 421 through the first exhaust pipe 422. The externally wound coil is wound around the first heat exchange tower 421 and / or the first exhaust pipe 422. The first hot water tank 434 supplies water to the externally wound coil through a first circulation pump 435. The hot water in the externally wound coil flows back to the first hot water tank 434 through the steam generation tank 436. The steam generated by the steam generation tank 436 is supplied to the double-wall sandwich cavity 211.

[0051] Quality-changing is a common knowledge. By mixing corresponding chemical agents in high-molecular-weight proteins, the high-molecular-weight proteins can be decomposed into low-molecular-weight proteins, and corresponding water is generated at the same time.

[0052] The spiral agitator 240 includes a core shaft extending axially along the inner cylinder 220 and a propeller blade connected to the core shaft. The core shaft is used for drivingly connecting to a motor. The propeller blade spirally extends axially along the inner cylinder 220. The propeller blade is used for stirring the materials in the inner cylinder 220 and also for driving the materials to move towards the blanking port 223.

[0053] It can be understood that between the crusher 110, the storage bin 120, the quality-changing machine 200, the press 310, the dryer 320, the cooler 330 and the grinder 350 connected in series in sequence, it means that the materials are sequentially transported along this path and the materials sequentially go through the corresponding processes; the materials can be transported between two adjacent devices through a conveyor belt. Refer to Figure 1, preferably, materials can be transported between two adjacent devices through a screw conveyor to perform enclosed transportation of the materials.

[0054] The second aspect of the embodiments provided by the present invention: an energy-saving and environmental-friendly complete set of animal protein processing technology, comprising the following steps:

[0055] Crushing and warehousing, the materials are crushed into pieces and fragments by a crusher 110, and the crushed materials are input into a silo 120 for warehousing; the amount of materials such as animal hair acquired each time is more or less. Less materials are not suitable for immediately carrying out a series of continuous treatments such as quality transformation, oil pressing, and drying. The present invention crushes and warehouses the materials to facilitate subsequent direct carrying out of a series of continuous treatments such as quality transformation, oil pressing, and drying. The materials such as animal hair acquired are generally in the form of filaments, strips, or blocks. When directly stored in the warehouse, there are gaps between the materials, and there will be many hollow areas in the silo 120. This warehousing method wastes warehouse space. The present invention crushes the materials and then warehouses them, effectively avoiding the hollow areas in the warehouse and effectively improving the utilization rate of the warehousing space of the silo 120.

[0056] Quality transformation and primary drying, chemicals and the materials exported from the silo 120 are input into the cylinder body of a quality transformation machine 200. The spiral stirring paddle 240 of the quality transformation machine 200 mixes the materials and the chemicals, decomposing the materials into small molecular weight protein powder particles and water. The materials or protein powder particles are continuously stirred and scraped by the spiral stirring paddle 240 to separate the water, and the protein powder particles are scraped to the discharge port of the quality transformation machine 200;

[0057] Oil pressing, the small molecular weight protein powder particles obtained by quality transformation are squeezed for oil by an oil press 310;

[0058] Drying after oil pressing, the small molecular weight protein powder particles after oil pressing are stirred and dried;

[0059] Cooling and pulverizing, the small molecular weight protein powder particles after drying are stirred and cooled, and then pulverized;

[0060] Deodorization and heat utilization, the odors discharged from the quality transformation machine 200, the oil press 310, and the dryer 320 are introduced into a burner. The tail gas formed by the combustion of the odors heats the water in the externally wound coil during the emission process. The steam generated by the hot water in the steam generating tank is introduced into the peripheral wall sandwich cavities of the quality transformation machine 200, the oil press 310, and the dryer 320. It can be understood that the peripheral wall sandwich cavity of the quality transformation machine 200 is the aforementioned double-wall sandwich cavity 211.

[0061] Crushing, squeezing and de-oiling, and pulverizing are common knowledge. The present invention can select conventional crushers 110, squeezers 310, and pulverizers 350. Crusher 110 and pulverizer 350 mainly include a box body and a cutting roller arranged in the box body. The outer peripheral wall of the cutting roller has a predetermined spacing with the inner wall of the box body. There are even two interlocking cutting rollers arranged in the box body. The outer peripheral wall of the cutting roller is distributed with multiple blades. When the material placed in the feed port falls through the predetermined spacing or the gap between the rollers, it is cut and crushed / pulverized. The pulverizer 350 can effectively crush the agglomerates produced by the squeezer 310. In the squeezer 310 (oil press / squeezing and de-oiling machine), the oil is squeezed out of the protein powder particles under the conditions of heating to increase the temperature and activating the oil molecules; the squeezer 310 can be a screw-driven type, a cylinder type (hydraulic / pneumatic), etc.

[0062] It is understandable that in the chemical machine 200, the feed port 221 passes through the peripheral wall of the outer cylinder 210, or passes through the sealing cover plate 214 on the right side of the outer cylinder 210; when the exhaust port 222 is provided at the right end of the inner cylinder 220, the exhaust port 222 passes through the peripheral wall of the outer cylinder 210. Animal hair and chemical agents can be placed into the inner cylinder 220 through the same feed port 221; the feed port 221 is divided into multiple parts to respectively introduce corresponding materials, which is equivalent replacement.

[0063] The dryer 320 and the cooler 330 both include a tank body and a stirring paddle disposed in the tank body. The interlayer cavity of the tank body peripheral wall of the dryer 320 is used to introduce steam, and the chamber of the cooler 330 is used to introduce cold air and discharge hot air.

[0064] It can be understood that the combustion furnace 410 is conventional knowledge, and the output ends of the odor inlet pipe 411, the fuel spray gun 412, the oxygen supply pipe 413 and the igniter 414 are all connected to the furnace of the combustion furnace 410. The distance between the discharge ports of the fuel spray gun 412, the oxygen supply pipe 413 and the igniter 414 is within a predetermined range (forming a flame combustion point), and the discharge port of the igniter 414 (i.e., the spark emission end / high temperature red hot end) faces the discharge port of the fuel spray gun 412 to ensure that the flame can be started; in order to ensure that the odor passes through the flame combustion point, the odor inlet pipe 411 is not lower than the flame combustion point. The fuel spray gun 412 sprays gas / extrudes fuel into the furnace, the oxygen supply pipe 413 sprays oxygen or air into the furnace, and the igniter 414 is used to ignite the gas / fuel by means of sparks or high heat; the odor is introduced into the combustion furnace 410 to make the odor burn. If the odor is burned, the combustion can be appropriately reduced.

[0065] Compared with the prior art, animal hair and chemical agents are used as materials and introduced into the inner cylinder 220; the spiral agitator 240 drives the mixing of the materials, so that under the catalysis of the chemical agent, the animal hair degrades from high molecular weight protein to low molecular weight protein, that is, the animal hair degrades into small particles; after moving a certain length (the axial length of the inner cylinder 220), it degrades and dries into small molecular weight protein powder particles during the movement, and finally falls out of the inner cylinder 220 from the material outlet 223; in the present invention, a filtering and integrated machine for degrading high molecular weight protein and synchronously drying is provided; the materials can be mixed, moved, and volatilize water vapor during stirring; the odor generated during production is eliminated by combustion, and the combustion heat of the odor is fully utilized to obtain water vapor, which is recycled for chemical quality, oil pressing, and drying, etc.

[0066] In some embodiments of the present invention, it further includes a metal detector 130. The metal detector 130 is used for the materials output by the input silo 120 and for conveying the materials to the chemical quality machine 200 after detecting and removing metal impurities. The energy-saving and environmental-friendly complete set of animal protein processing technology also includes a metal detection step. After the materials output by the silo 120 are detected and removed of metal impurities, they are then subjected to chemical quality, pressing, and stirring and drying, etc. The present invention removes metal impurities, avoids the resistance or interference of metal impurity parts to mechanical actions such as pushing and stirring, and effectively protects the equipment.

[0067] In some embodiments, the metal detector 130 includes a magnetic belt. The magnetic belt is used for conveying materials. When the metal impurities are brought below the magnetic belt, they are removed by a scraper or the like.

[0068] In some embodiments, the metal detector 130 includes a conveyor belt and a magnetic belt. One end of the magnetic belt is located above the conveyor belt, and the other end is far from the conveyor belt. The conveyor belt is used for conveying materials, and the magnetic belt is used for adsorbing impurities in the materials on the conveyor belt.

[0069] In some embodiments of the present invention, a screening machine 340 is arranged between the dryer 320 and the crusher 350. There is a screening step before the cooling and crushing step. The materials may be doped with non-protein impurities, and it is difficult to turn the impurities into powder particles after chemical quality. The impurity blocks are screened out before the crushing step. The common screening machine 340 includes a screen mesh and a power structure for driving the screen mesh to vibrate. The screening machine 340 can also be in the form of a rolling cage.

[0070] In some embodiments of the present invention, a weighing and packaging machine 360 is connected in series at the output end of the crusher 350. Weighing and bagging can be seen in other fields. In the present invention, from the crushing of the materials when they enter the factory to the quantitative packaging of the finished products, a complete automated production line is realized, which can effectively improve the production efficiency.

[0071] In some embodiments of the present invention, the cylinder body includes an inner cylinder 220 and a horizontal outer cylinder 210. A double-wall sandwich cavity 211 is provided on the peripheral wall of the outer cylinder 210. A steam joint 212 communicating with the double-wall sandwich cavity 211 is provided in the middle and / or upper end of the outer cylinder 210. The inner cylinder 220 passes through the channel of the outer cylinder 210. One end of the inner cylinder 220 protrudes out of the outer cylinder 210. The other end of the inner cylinder 220 is provided with a feeding port 221. One or more exhaust ports 222 are provided at the upper end of the inner cylinder 220. A blanking port 223 is provided at one end of the inner cylinder 220. A spiral stirring paddle 240 is arranged in the inner cylinder 220. A mesh liquid leakage bottom plate 224 is provided in the section of the inner cylinder 220 located in the outer cylinder 210. The lower end of the inner cylinder 220 and the lower end of the outer cylinder 210 are distributed at intervals to form a liquid drainage channel 230. Sealing covers 214 are provided at the left and right ends of the outer cylinder 210 to seal the gap between the outer cylinder 210 and the inner cylinder 220. A liquid drainage joint 231 communicating with the liquid drainage channel 230 penetrates through the lower end and / or middle of the outer cylinder 210. In the initial drying step of the chemical substance, the moisture generated by the chemical substance can be discharged outward through the liquid leakage bottom plate 224, the liquid drainage channel 230 and the liquid drainage joint 231, that is, the moisture is filtered. The moisture can also be vaporized by heat during stirring and discharged through the exhaust port 222. These two ways enable the small molecular weight protein to be quickly dried. One end of the inner cylinder 220 protrudes out of the outer cylinder 210. After the small molecular weight protein powder particles are chemically treated and dried and have been cooled to a certain extent, they can be discharged through the blanking port 223.

[0072] The steam joint 212 can be only used for introducing steam. After the heat of the steam is absorbed to dry the protein powder particles, the steam is liquefied into water and flows out of the outer cylinder 210 through the drainage joint 213.

[0073] The steam joint 212 can also be composed of a steam input head and a steam output head. The steam input head and the steam output head are arranged on the front side and / or rear side of the outer cylinder 210. The steam output head can communicate with the steam return port of the steam generating tank. The steam input head communicates with the exhaust port of the steam generating tank. The drainage joint 213 can communicate with the upper end of the liquid bubble tube. The upper and lower ends of the liquid bubble tube respectively communicate with the steam return port and the water return port of the steam generating tank to return the steam and the liquefied water. In the present invention, the peripheral wall of the outer cylinder 210 is used to maintain the flow of steam, avoid the stagnation of steam, avoid the stagnation of heat supplement, and keep a relatively high temperature inside the outer cylinder 210. Refer to Figure 2 , one of the left end and the right end on the front side of the outer cylinder 210 is provided with a steam input head, and the other is provided with a steam output head. In the present invention, when the amount of water leaking into the liquid drainage channel 230 is small, the water can be evolved into steam by heat and flow out through the liquid drainage joint 231. In addition, the end cover is disassembled, and the spiral stirring paddle 240 can be detached to maintain and clean the spiral stirring paddle 240 and the inner cylinder 220.

[0074] It is understandable that the animal hair is degraded and crushed into powder particles, and the liquid leakage holes of the liquid leakage bottom plate 224 have a certain aperture for leaking water and reducing the passage of protein particles.

[0075] In some embodiments of the present invention, the inner cylinder 220 and the outer cylinder 210 are concentrically arranged.

[0076] Refer to Figure 5 , in some embodiments of the present invention, the inner cylinder 220 is eccentrically upward relative to the outer cylinder 210, and the upper end of the inner cylinder 220 is spliced with the upper end of the outer cylinder 210.

[0077] Refer to Figure 3 and Figure 5 , preferably, windows are provided at the upper ends of both the inner cylinder 220 and the outer cylinder 210. The upper ends of the inner cylinder 220 and the outer cylinder 210 are spliced, and their windows coincide. The left and right ends of the windows extend to the left and right ends of the outer cylinder 210 respectively. A window frame 215 is integrally formed at the upper end of the outer cylinder 210. The window frame 215 extends upward from the edge of the window. A door panel is provided at the upper port of the window frame 215. The door panel can be opened, or one or more working ports 216 are provided on the door panel, and a cover plate 217 is connected to the working port 216. In the present invention, the energy-saving and environment-friendly complete animal protein processing technology further includes a maintenance and cleaning step. Through the window or the working port 216, the inner cylinder 220 and the screw agitator 240 can be maintained and cleaned.

[0078] Refer to Figure 3 and Figure 5 , preferably, the peripheral wall of the working port 216 is formed by protruding the door panel. A plurality of locking cover bolts 218 are distributed at intervals along the circumferential direction of the working port 216. A plurality of notches are formed at the edge of the cover plate 217. The notches correspond to the locking cover bolts 218 one by one. One end of the locking cover bolt 218 is hinged to the peripheral wall of the working port 216, and the other end is threadedly connected to the nut 219 of the pressing cover 264. The locking cover bolt 218 is used to buckle into the corresponding notch, and the nut 219 of the pressing cover 264 is used to press the cover plate 217. In the present invention, by loosening a small section of the nut 219 of the pressing cover 264, the locking cover bolt 218 can be disengaged, and the cover plate 217 can be quickly disassembled without completely disassembling the nut 219 of the pressing cover 264.

[0079] Preferably, the cover plate 217 is connected with a handle.

[0080] Refer to Figure 3 and Figure 5, in some embodiments of the present invention, it further includes a cylindrical liquid leakage mesh plate 250. The section of the inner cylinder 220 located in the outer cylinder 210 is used to accommodate the liquid leakage mesh plate 250. The outer wall of the liquid leakage mesh plate 250 abuts against the inner wall of the inner cylinder 220, and the right end of the inner cylinder 220 can extract the liquid leakage mesh plate 250. It can be understood that if the feed port 221 penetrates the peripheral wall of the outer cylinder 210, then the liquid leakage mesh plate 250 is provided with an opening corresponding to the feed port 221. In the present invention, the spiral stirring paddle 240 and the liquid leakage mesh plate 250 are the main components prone to dirt. The liquid leakage mesh plate 250 can be extracted to mainly clean the liquid leakage mesh plate 250 and reduce the cleaning intensity of the inner cylinder 220.

[0082] Refer to Figure 3 and Figure 5 , in some embodiments of the present invention, the two-layer walls of the outer cylinder 210 are connected by a plurality of rib plates. The plurality of rib plates are axially spaced along the outer cylinder 210, so that the double-wall sandwich cavity 211 of the outer cylinder 210 is divided into a plurality of compartments, and two adjacent compartments are connected through the through holes of the rib plates.

[0083] Refer to Figure 3 and Figure 4 , in some embodiments of the present invention, the end cover is connected with a bearing seat 261. The end of the core shaft of the spiral stirring paddle 240 is provided with a copper sleeve 262. A plurality of rings 263 are axially distributed on the outer peripheral wall of the copper sleeve 262. The copper sleeve 262 is in rolling connection with the bearing seat 261 through the rings 263. The gland 264 and the bearing seat 261 jointly limit the plurality of rings 263 to prevent the rings 263 from detaching from the copper sleeve 262 and the bearing seat 261. Preferably, the bearing seat 261, the rings 263 and the gland 264 are all made of metal materials.

[0084] Refer to Figures 2 to 4 , preferably, the outer cylinder 210 and the inner cylinder 220 are welded together.

[0085] Refer to Figure 3 , the outer cylinder 210 is formed by welding a variety of plates.

[0086] The externally wound coil includes a first wound pipe coil 431 and a first wound tower coil 432. The first wound pipe coil 431 is used for winding the first exhaust pipe 422, and the first wound tower coil 432 is used for winding the first heat exchange tower 421.

[0087] In some embodiments of the present invention, the first built-in coil 433 spirals from bottom to top in the first heat exchange tower 421 with a reduced diameter, the lower end of the first built-in coil 433 is higher than the air inlet of the first heat exchange tower 421, the first hot water tank 434 supplies water to the first built-in coil 433 through the first circulation pump 435, and the steam generator tank 436 receives the hot water derived from the first built-in coil 433. The first built-in coil 433 spirals upward in a reduced diameter manner, and the large end of the reduced diameter coil is used to receive the exhaust gas in a guided manner, so that the exhaust gas can flow better along the channel wrapped by the first built-in coil 433, and the first built-in coil 433 can absorb a large proportion of the exhaust heat.

[0088] In some embodiments of the present invention, the steam generation tank 436 is also used for heat exchange with the first exhaust pipe 422 .

[0090] In some embodiments of the present invention, the first tower coil 432, the first built-in coil 433 and the first pipe coil 431 are connected in parallel to the first circulation pump 435. Among the three water paths, the hot water flowing out of the first tower coil 432 is at a lower temperature, while the hot water flowing out of the first built-in coil 433 and the first pipe coil 431 is at a higher temperature.

[0091] Reference Figure 6 and Figure 7 In some embodiments of the present invention, after the first tower winding coil 432 and the first tube winding coil 431 are connected in series, they are connected to the first circulation pump 435 in parallel with the first built-in coil 433. In the two water paths formed, the built-in water path directly absorbs the high-temperature exhaust gas in the first heat exchange tower 421, and then discharges high-temperature hot water to the steam generator tank 436. In the external water path, the heat of the tower body of the first heat exchange tower 421 is initially absorbed, and then further heated by the higher-temperature first exhaust pipe 422, so that the external water path also flows out high-temperature hot water. All water paths flow out high-temperature hot water, and the present invention volatilizes steam better.

[0092] Reference Figure 6 and Figure 7 Better yet, both the first tower winding coil 432 and the first built-in coil 433 use the upper ports as water inlets, that is, both the first tower winding coil 432 and the first built-in coil 433 are connected to the first circulation pump 435 at the upper ends. The water pumped to the upper ends of the first tower winding coil 432 and the first built-in coil 433 can flow from top to bottom autonomously after being separated from the power of the first circulation pump 435. The water pressure in the first tower winding coil 432 and the first built-in coil 433 will not squeeze the first circulation pump 435, and the first circulation pump 435 is relatively lightly loaded.

The second built-in coil 443 is spirally coiled with a reduced diameter from bottom to top. The lower end of the second built-in coil 443 is higher than the air inlet of the second heat exchange tower 451. A second tower-wrapping coil 444 is wound around the outside of the second heat exchange tower 451. A second pipe-wrapping coil 445 is wound around the outside of the second exhaust pipe 452. The second hot water tank 441 supplies water to the second tower-wrapping coil 444, the second built-in coil 443 and the second pipe-wrapping coil 445 through the second circulation pump 442. The second tower-wrapping coil 444, the second built-in coil 443 and the second pipe-wrapping coil 445 are used to return hot water to the second hot water tank 441. In the step of deodorization heat utilization, on the exhaust path of the tail gas, the tail gas heat is utilized in sections. The high-temperature section is used to generate water vapor for material steaming, and the low-temperature section is used to generate hot water for material bathing or external supply, etc.

[0094] The hot water in the first hot water tank 434 is gradually turned into water vapor, and the water level in the first hot water tank 434 gradually drops. Referring to Figure 6 , preferably, the second hot water tank 441 supplies water to the first tower-wrapping coil 432, the first built-in coil 433 and the first pipe-wrapping coil 431 through the first makeup water pump 437. In the step of deodorization heat utilization, the water supplemented to the first tower-wrapping coil 432, the first built-in coil 433 and the first pipe-wrapping coil 431 is water with a certain amount of heat, ensuring that during the water replenishment period, the first tower-wrapping coil 432, the first built-in coil 433 and the first pipe-wrapping coil 431 continuously generate high-temperature hot water to ensure the continuous production of steam.

[0095] Preferably, the first hot water tank 434 is provided with a water level gauge. When the first hot water tank 434 is at a low water level, hot water is replenished to the loop where the first hot water tank 434 is located.

[0096] Preferably, the output ends of both the first circulation pump 435 and the first makeup water pump 437 are respectively connected with corresponding on-off valves. The first circulation pump 435 and the first makeup water pump 437 respectively supply water to the first tower-wrapping coil 432, the first built-in coil 433 and the first pipe-wrapping coil 431 through the corresponding on-off valves. During the water replenishment process, the operation of the first circulation pump 435 can be stopped, and the first circulation pump 435 can also be protected from interception through the corresponding on-off valve; when the first hot water tank 434 is not at a low water level, the operation of the first makeup water pump 437 can be stopped, and the first makeup water pump 437 can also be protected from interception through the corresponding on-off valve. The on-off valve can be an electromagnetic valve or a common manual on-off valve, such as a ball valve.

[0097] Referring to Figure 6 , in some embodiments of the present invention, it further includes a make-up water tank 460 and a second make-up water pump 446. The make-up water tank 460 supplies water to the second tower coil 444, the second built-in coil 443, and the second coiled tube 445 through the second make-up water pump 446.

[0098] During the elimination of tail gas combustion, carbon ash may be generated and doped in the tail gas. In some embodiments of the present invention, it further includes a draft fan 470. The air outlet of the second heat exchange tower 451 away from the first heat exchange tower 421 discharges the tail gas through the draft fan 470. The present invention extracts the tail gas in a negative pressure manner, improves the flow of the tail gas in the tower and the pipe, and reduces the adhesion of carbon ash on the exhaust pipe, the built-in coil, and the tower wall.

[0099] During the elimination of tail gas combustion, carbon ash may be generated and doped in the tail gas. In some embodiments of the present invention, it further includes a spray tower. The air outlet of the second heat exchange tower 451 away from the first heat exchange tower 421 discharges the tail gas through the spray tower. The spray tower includes a tower body and atomizing nozzles arranged in the tower. When the tail gas flows through the spray tower, water vapor settles the dust in the tail gas.

[0100] Preferably, the quality improving machine 200, the pressing machine 310, and the drying machine 320 are connected to the deodorizing device 400 through a spray dust removal tower; under heating conditions, the odors generated by the quality improving machine 200, the pressing machine 310, and the drying machine 320 may be doped with certain dust, and the dust is settled by spraying. Preferably, hot water is sprayed in the spray dust removal tower to reduce the water solubility rate of the odor in the spray dust removal tower, and the deodorizing device 400 is used to supply hot water to the spray dust removal tower.
