Description

Technical Field

[0001] This utility model relates to a device for treating the exhaust gas from feed enzyme fermentation, belonging to the field of feed enzyme technology. Background Technology

[0002] Feed enzyme preparations are enzymes added to feed to improve the digestion and utilization of feed by animals or to improve the metabolic efficiency of animals. During their fermentation production process, a large amount of exhaust gas is generated. These exhaust gases are complex in composition and usually contain ammonia nitrogen, sulfur-containing organic waste gas, and a large amount of high-temperature and high-pressure water vapor. They may also contain some organic raw materials, semi-finished products or metabolites, and have a strong pungent odor. If they are discharged directly without effective treatment, they will not only pollute the atmospheric environment, but may also harm the health of surrounding organisms and humans.

[0003] In the current technology for exhaust gas treatment, the replacement of adsorption materials is very inconvenient. Taking the commonly used activated carbon adsorption material as an example, traditional devices usually fix the activated carbon in the adsorption box or adsorption tower. When the activated carbon is saturated and needs to be replaced, the entire adsorption device must be shut down and disassembled, which consumes a lot of manpower and time and affects production efficiency.

[0004] Therefore, a device for treating the exhaust gas from feed enzyme fermentation is proposed. Utility Model Content

[0024] Example 2 like Figure 4-6As shown, in one embodiment, the buffer mechanism 300 includes a buffer tank 301, which is disposed on the left side of the adsorption tower 201. An air inlet pipe 302 is connected to the top of the buffer tank 301 and is connected to the exhaust pipe of the fermenter. A drain pipe 303 is connected to the bottom of the buffer tank 301. A jacket layer 304 is provided in the inner cavity of the buffer tank 301. A condensate inlet 305 is connected to the top of the jacket layer 304, and a condensate outlet 306 is connected to the left side of the jacket layer 304. The separation mechanism 400 includes a cyclone separator. The separator body 401 is located to the left of the adsorption tower 201 and to the right of the buffer tank 301. A discharge port is located at the bottom of the cyclone separator body 401. The alkali washing mechanism 500 includes an alkali washing tower 501, which is located to the left of the adsorption tower 201 and to the right of the cyclone separator body 401. An alkali solution box 502 is fixedly connected to the right side of the alkali solution box 501. A connecting pipe 503 is connected to the left side of the alkali solution box 502, and the connecting pipe 503 is located inside the alkali washing tower 501. The bottom of the alkali washing tower 501 is connected to multiple equidistantly distributed and identically sized atomizing nozzles 504. A circulating water pump 505 is connected to the right side of each atomizing nozzle 504. The other end of the circulating water pump 505 is connected to the right side of the alkali solution box 502. A guide plate 506 is fixedly connected to the bottom of the inner cavity of the alkali washing tower 501, and the guide plate 506 is triangular. A connecting device 600 is provided between the adsorption mechanism 200, the buffer mechanism 300, the separation mechanism 400, and the alkali washing mechanism 500. The connecting device 600 includes a first connecting pipe 601 and a second connecting pipe 602. The buffer tank 301 and the cyclone separator body 401 are connected by the first connecting pipe 601, the cyclone separator body 401 and the alkaline washing tower 501 are connected by the second connecting pipe 602, and the adsorption tower 201, the alkaline washing tower 501 and the adsorption tower 201 are connected by the third connecting pipe 603.

[0026] In operation, the exhaust gas generated during the fermentation of feed enzyme preparations first enters the buffer tank 301. The high-temperature water vapor in the exhaust gas is cooled by condensate in the jacket layer 304 within the buffer tank 301. Some of the water vapor condenses into water and is discharged through the drain pipe 303. After initial buffering and cooling, the exhaust gas enters the cyclone separator body 401 from the first connecting pipe 601 at the top of the buffer tank 301. Centrifugal force separates the liquid and solid impurities in the exhaust gas within the cyclone separator body 401. The separated exhaust gas then enters the alkaline washing tower 501 from the second connecting pipe 602 on the right side of the cyclone separator body 401. Inside the alkaline washing tower 501, the exhaust gas comes into full contact with the alkaline solution sprayed from the atomizing nozzle 504. The alkaline solution absorbs impurities from the exhaust gas. Acidic harmful gases are partially recycled back into the alkali solution box 502 via the circulating water pump 505. The tail gas after alkali washing enters the adsorption tower 201 from the third connecting pipe 603 at the top of the alkali washing tower 501. Inside the adsorption tower 201, the tail gas passes through each adsorption layer 203 in sequence. The adsorption layers 203 adsorb the residual odors and trace harmful components in the tail gas. The purified tail gas is discharged into the atmosphere through the tail gas fan 205. When a certain adsorption layer 203 in the adsorption tower 201 needs to be replaced, the corresponding sealing door 204 is opened, the adsorption layer 203 is pulled out of the tower body along the locking block 202, a new adsorption layer 203 is replaced, and then it is pushed back into the tower body along the locking block 202. The sealing door 204 is closed, and normal operation is restored.
