[0002] Ammonia, also known as "ammonia gas," is a compound of nitrogen and hydrogen. It is a colorless gas with a strong, pungent odor and is extremely soluble in water. At room temperature and pressure, one volume of water can dissolve 700 times its volume of ammonia. The aqueous solution is also known as ammonia water. Therefore, most ammonia removal devices currently use packed towers to purify ammonia-containing waste gas.

[0003] For example, patent document CN220573108U discloses a novel steam ammonia removal device, specifically including a dilute sulfuric acid tank, an ammonia removal pipe and a steam inlet pipe on the dilute sulfuric acid tank, the ammonia removal pipe and the steam outlet pipe being fixedly connected to the dilute sulfuric acid tank, several layers of packing material arranged in the extension direction of the ammonia removal pipe, several nozzles also arranged in the extension direction of the ammonia removal pipe, and a spray pump also arranged on one side of the dilute sulfuric acid tank, the spray pump being connected to the nozzles through a spray pipe, and the spray pump being connected to the dilute sulfuric acid tank; through the above technical solution, dilute sulfuric acid is sprayed onto the packing layer through several nozzles, and the waste gas comes into contact with the dilute sulfuric acid on the packing layer to remove ammonia, which can remove most of the ammonia in the waste gas, but some ammonia will still not be completely removed, the ammonia removal effect is not good, and the discharge of ammonia-containing waste gas is likely to cause environmental pollution.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] To address the technical problem in existing ammonia removal devices that purify waste gas through spraying ammonia removal liquid, where some ammonia may not be completely absorbed, this solution provides an ammonia removal device that sprays and washes the waste gas before filtering it with an activated carbon adsorber, ensuring that the ammonia removal device can more effectively remove ammonia from the waste gas.

[0027] Please see Figures 1-5 , Figures 1-5An ammonia removal device according to one embodiment of the present invention includes an ammonia removal cylinder 1, a water washing mechanism 2, and an activated carbon adsorber 3. The ammonia removal cylinder 1 includes a cylinder body 11, a sleeve 12, and multiple air guide components 13. The sleeve 12 is fixedly connected to the cylinder body 11 and passes through the cylinder body 11, forming a washing chamber between the sleeve 12 and the cylinder body 11. The multiple air guide components 13 are circumferentially installed on the sleeve 12 and can guide the airflow in the washing chamber into the sleeve 12. The cylinder body 11 is provided with an air inlet end 11a communicating with the washing chamber and an exhaust end 11b communicating with the top of the sleeve 12. The water washing mechanism 2 is installed in the washing chamber and is used to wash the airflow entering the washing chamber through the air inlet end 11a. The activated carbon adsorber 3 is installed in the sleeve 12 and is used to filter the airflow output by the multiple air guide components 13.

[0028] In actual use, ammonia-containing waste gas is transported to the washing chamber through the inlet 11a. When the waste gas rises in the washing chamber, the water washing mechanism 2 can wash the waste gas with water, which can remove some of the ammonia in the waste gas. Subsequently, the waste gas is transported to the sleeve 12 through the air guide. During the process of the waste gas rising in the sleeve 12, the activated carbon adsorber 3 can further absorb the ammonia in the waste gas. After being filtered twice, the waste gas can remove the ammonia in the waste gas more thoroughly, and the ammonia removal effect is better.

[0029] It should be noted that the water washing mechanism 2 is not limited to a specific structure, as long as it can spray water to wash the exhaust gas, no other limitations are made here.

[0030] Specifically, in one embodiment, the water washing mechanism 2 includes a packing element 21 and a spray element 22, which are installed in the washing chamber, and the spray element 22 is located above the packing element 21. The spray element 22 is used to spray ammonia removal liquid onto the packing element 21.

[0031] It is understood that the packing component 21 includes two sieve plates 211 and a plurality of Pall rings 212, with the two sieve plates 211 installed at intervals in the washing chamber and the plurality of Pall rings 212 filling the space between the two sieve plates 211.

[0032] Furthermore, the spray element 22 sprays ammonia removal liquid onto the packing element 21. The ammonia removal liquid adheres to multiple Pall rings 212. When the exhaust gas rises in the washing chamber, it can come into contact with the ammonia removal liquid on the Pall rings 212, and the ammonia in the exhaust gas can be absorbed by the ammonia removal liquid.

[0033] It should be noted that the spraying component 22 includes a spray pipe and multiple atomizing spray heads. The spray pipe is located inside the washing chamber and is circular in shape. Multiple atomizing spray heads are installed at intervals on the spray pipe. The ammonia removal liquid is sprayed into the washing chamber through the atomizing spray heads. Specifically, the ammonia removal liquid can be clean water. The principle is to utilize the high water solubility or chemical reaction characteristics of ammonia gas to transfer it from the gas phase to the liquid phase through spray absorption liquid, thereby achieving purification. Ammonia gas is extremely soluble in water (at room temperature, 1 volume of water can dissolve approximately 700 volumes of ammonia gas).

[0034] Based on the above scheme, in order to ensure that the exhaust gas is evenly dispersed into the washing chamber, the water washing mechanism 2 specifically includes a diffuser plate 23, which is installed in the washing chamber and is located between the air inlet 11a and the packing member 21.

[0035] It should be noted that the activated carbon adsorber 3 is not limited to a specific type of mechanism, as long as it can purify the waste gas, no other limitations are made here.

[0036] Specifically, in one embodiment, the activated carbon adsorber 3 includes a mounting plate 31, a plurality of positioning cylinders 32, and a plurality of cloth bag cylinders 33. The mounting plate 31 is fixedly connected to the sleeve 12. The mounting plate 31 has a plurality of through holes. The plurality of positioning cylinders 32 are all fixedly connected to the mounting plate 31, and the top opening of each positioning cylinder 32 corresponds to each of the through holes. Each positioning cylinder 32 has a plurality of vent holes 32a. Each cloth bag cylinder 33 is disposed in each positioning cylinder 32, and the cloth bag cylinder 33 contains activated carbon adsorbent.

[0037] Based on the above scheme, in order to further remove ammonia from the exhaust gas, a scrubbing mechanism 4 is specifically included. The scrubbing mechanism 4 includes a vertical pipe 41, a shaft 42, a spiral blade 43, multiple nozzles 44, and a sealing member 45. The top of the vertical pipe 41 passes through the sleeve 12 and the bottom is fixedly connected to the sleeve 12. The top of the vertical pipe 41 is provided with multiple vent holes 41a for airflow from the sleeve 12 to the vertical pipe 41. The shaft 42 is coaxially arranged inside the vertical pipe 41 and has a liquid guiding channel along the axial direction. The spiral blade 43 is fixed on the shaft 42, and the spiral blade 43 and the vertical pipe 41 enclose a continuous curved channel. Multiple nozzles 44 are installed on the shaft 42 and connected to the liquid guiding channel. The sealing member 45 is connected to the top of the cylinder 11 and is used to open or close the exhaust end 11b.

[0038] Understandably, the exhaust gas inside the sleeve 12 can be transported to the vertical pipe 41 through multiple vent holes 41a. The exhaust gas flows in a continuous curved channel, and multiple nozzles 44 on the shaft 42 spray ammonia removal liquid into the curved channel, which can further absorb the ammonia in the exhaust gas.

[0039] It should be noted that, in one embodiment, the bottom of the vertical pipe 41 extends to the outside of the sleeve 12 and is provided with a drain end 41b. It can be understood that the waste gas and ammonia removal liquid in the vertical pipe 41 can be output from the drain end 41b.

[0040] Based on the above scheme, in order to ensure that the exhaust gas in the sleeve 12 can enter the vertical pipe 41, the exhaust end 11b must be closed by the sealing member 45; when it is necessary to replace the activated carbon adsorbent in the bag tube 33, the exhaust end 11b can be opened by the sealing member 45.

[0041] It should be noted that the sealing component 45 is not limited to a specific structure. Specifically, the sealing component 45 includes a sealing plate, a sealing ring, and multiple locking screws. The sealing plate has multiple connecting holes, and the top of the cylinder has multiple threaded holes. The locking screws pass through the connecting holes and are screwed into the threaded holes. The sealing ring is pressed between the sealing plate and the top of the cylinder.

[0042] In one embodiment, the air guide 13 includes an air guide tube, one end of which is fixedly connected to the sleeve 12 and communicates with the washing chamber, and the other end of which extends to the inner bottom of the sleeve 12. It should be noted that the airflow in the sleeve 12 can enter the positioning cylinder 32 through multiple air vents 32a, and the ammonia in the waste gas can be absorbed by the activated carbon adsorbent contained in the bag cylinder 33.

[0043] In addition, the bottom of the cylinder 11 is provided with a liquid outlet 11c that communicates with the washing chamber, and the ammonia removal liquid sprayed into the washing chamber can be discharged through the liquid outlet 11c.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
