[0046] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0047] 1. Multiple scrubbing components are installed. The intake speed of the exhaust gas is controlled by the injection operation pipe, the dispersion multi-hole frame, the linkage control valve, and the injection fan. This, combined with small-hole intake, large-hole diversion, and small-hole counter-flushing, disperses the exhaust gas. The amount and speed of injected dilute sulfuric acid are controlled by the acid injection pipe frame, dispersion spray heads, acid storage tank, booster pump, and linkage control valve. The sprayed dilute sulfuric acid forms a rain curtain, which contacts the exhaust gas. By increasing the contact area, the rising speed of ammonia in the exhaust gas is slowed, maximizing contact. A small amount of dilute sulfuric acid is used to continuously flush the reaction. A gas detector monitors the concentration of ammonia flowing to the top, and the gas is then returned for further processing. The pipe and injection fan drive the high-concentration ammonia gas at the top to flow back to the bottom, realizing a cyclic reaction treatment. The multi-chamber segmented treatment increases the reaction time and controls the reaction volume. In conjunction with the repeated reaction chamber at the top, excess dilute sulfuric acid is used to treat the small amount of ammonia remaining in the tail gas, achieving complete ammonia removal. The tail gas is extracted and injected into water using the absorption exhaust chamber, U-shaped injection pipe, inlet and outlet pipes, linkage control valve, and injection fan, achieving water-soluble ammonia removal and improving the ammonia removal effect. Through multi-stage separation and small-scale continuous mixing reaction, the full reaction of ammonia gas and dilute sulfuric acid in the tail gas is controlled, improving the stability of ammonia removal and production of ammonium sulfate, and reducing resource waste and environmental pollution.

[0048] 2. The ammonium sulfate solution and ammonium bisulfate solution are separated by a liquid-liquid drain pipe and then collected in a receiving and concentrating tank and a separation and collection tank. The receiving and concentrating tank is heated and cooled by a temperature controller, and the internal pressure of the receiving and concentrating tank is controlled by a pressure control pipe and a pressure control pump to achieve temperature-controlled concentration. The unsaturated ammonium sulfate solution is concentrated into a supersaturated solution. The lifting hydraulic cylinder and the switching motor drive the switching operation frame, the load-bearing crystallization plate and the crystallization rope to be inserted into the inside of the receiving and concentrating tank. At this time, the cooling and crystallization guidance process is used to achieve rapid crystallization of the ammonium sulfate solution, ensuring the stability of continuous production and continuous processing.

[0049] 3. Through the intake velocity control, exhaust velocity control and exhaust collision processing, by circulating linkage intake and exhaust, a small amount of dilute sulfuric acid repeated washing reaction, excessive dilute sulfuric acid fully deamination treatment, water soluble ammonia absorption treatment, segmented separation and external discharge treatment, low pressure medium temperature evaporation concentration and normal pressure low temperature guided crystallization, effectively solve the existing technology, ammonia gas in the tail gas washing, unable to control the reaction of ammonia and dilute sulfuric acid, resulting in unstable product and incomplete ammonia reaction, reduce the amount of dilute sulfuric acid, while avoiding ammonia excessive discharge, thereby avoiding the direct discharge of ammonia gas resulting in environmental pollution, while ensuring the stability of the product, reduce resource waste, improve the speed and stability of ammonium sulfate production.

[0050] 4. The material is removed from the filter washing assembly, which moves the inlet and outlet positioning plate and the collection and processing box by driving the inlet and outlet electric sliding rail. The pressure removal treatment plate is inserted into the top of the side end of the crystallization treatment rope, and the pressure removal electric sliding rail drives the pressure removal treatment plate to press and separate the ammonium sulfate crystals adhered to the side end of the crystallization treatment rope. The discharge electric sliding rail drives the discharge scraper to push the ammonium sulfate crystals into the inside of the dissolution treatment box. Finally, the ammonium sulfate crystals are pushed into the dissolution treatment box. The pressure removal treatment and the movement of the discharge treatment are inserted to press and separate the ammonium sulfate crystals and crush the treatment, which is convenient for subsequent crystal dissolution and purification treatment, and improves the convenience of subsequent treatment.

[0051] Hot water is injected into the dissolution treatment box through the hot liquid injection pipe, and the ammonium sulfate crystals and hot water are mixed and dissolved by the dissolution motor and the mixing and stirring frame. The ammonium sulfate solution is extracted by the discharge pump and the discharge operation pipe and injected into the double cavity filtrate box. The activated carbon adsorbent in the adsorption net cage and the limiting net plate are used to remove the solution. The vacuum filter is used for vacuum filtration treatment, and the cooling condenser is used for cooling crystallization treatment, which improves the purity of ammonium sulfate and ensures the speed and stability of subsequent granulation.

[0052] In summary, through the cooperation of multiple washing and crystallization assemblies and material removal and filtration assemblies, multiple reaction treatments, multiple discharge treatments, concentrated crystallization production, hot dissolution stirring treatment, interception adsorption slag removal and vacuum suction filtration treatment are used to realize the full reaction and purification of ammonium sulfate, improve the purity of ammonium sulfate, ensure the stability of product production and the stability of subsequent granulation, and fully absorb the reaction to remove ammonia gas in the tail gas, avoid the direct discharge of ammonia gas resulting in environmental pollution, and improve the steady protection of the environment during tail gas treatment and fertilizer production.

[0103] The working principle and use process of the application are as follows: when the tail gas after washing and desulfurization is subjected to ammonia gas adsorption treatment, the staff pours 20% to 30% dilute sulfuric acid into the acid liquid storage box 219, and pours water used for temperature control into the temperature control circulating box 220, at this time, the water is heated to 80 DEG C by the cold and hot temperature controller 223, the hot water in the temperature control circulating box 220 is extracted by the booster pump 221 and the reciprocating temperature control pipe 218, and the hot water is injected into the temperature control circulating cavity 217, so that the temperature control treatment is carried out on the constant temperature washing tower 202, and the internal temperature is always kept between 70 DEG C and 80 DEG C, and the temperature of the water in the temperature control circulating box 220 is adjusted to keep the internal temperature constant, so that the reaction speed and the dissolution rate are improved.

[0104] When the temperature adjustment is completed, the tail gas is extracted by the injection operation pipe 208 and the injection fan 238, and is injected into the dispersion porous frame 206 along the injection operation pipe 208, the tail gas is subjected to shunt treatment by the dispersion porous frame 206, and when the tail gas is injected into the dispersion porous frame 206, the gas flow space is increased and the gas flow speed is reduced, and when the tail gas is discharged, the gas flow is accelerated and collides with each other due to the limitation of the exhaust hole, so that the turbulent flow is formed, thereby slowing down the gas flow speed, and reducing the speed of the tail gas discharge and the uniformity of the tail gas dispersion.

[0105] At this time, the dilute sulfuric acid inside the acid liquid storage tank 219 is extracted by the booster pump 221 and the acid liquid injection pipe frame 209, and the dilute sulfuric acid is sprayed upwards along the acid liquid injection pipe frame 209 and the dispersion spray head 210, forming a rain curtain. When the ammonia tail gas enters the first repeated reaction chamber 203, the injection amount of dilute sulfuric acid is controlled according to the ammonia content in the tail gas. At this time, the ammonia is excessive, the dilute sulfuric acid is less, and the dilute sulfuric acid and the ammonia are fully reacted to generate ammonium sulfate. The tail gas continues to flow upwards, slows down and condenses through the interception net plate 212, and then moves to the position of the gas detector 211. The gas detector 211 detects the ammonia content in the rising tail gas. When the ammonia concentration is high, the top tail gas is recycled and discharged to the bottom by the injection fan 238 and the return treatment pipe 213. At this time, the tail gas reacts with dilute sulfuric acid again to produce ammonium sulfate;

[0106] When the ammonia concentration is low, the injection operation pipe 208 is closed by the linkage control valve 237, and at the same time the concentrated upper discharge pipe frame 207 is opened by the linkage control valve 237. At this time, the ammonia in the first repeated reaction chamber 203 is extracted by the injection fan 238 and the concentrated upper discharge pipe frame 207 and injected into the inside of the dispersion porous frame 206 to realize ammonia discharge. At this time, the dilute sulfuric acid is sprayed by the dispersion spray head 210 in the second repeated reaction chamber 203, and the amount of dilute sulfuric acid is controlled according to the ammonia content to generate ammonium sulfate again. At the same time, the gas detector 211 in the first repeated reaction chamber 203 continuously detects the ammonia at the top end. When the ammonia concentration is lower than the detection value, the injection operation pipe 208 is opened and the concentrated upper discharge pipe frame 207 is closed. In the reaction process, the ammonia flows upwards along the bottom of the repeated reaction chamber 203 and finally flows to the position of the gas detector 211 for detection again. When the ammonia content is excessive, the top ammonia is recycled and returned to the bottom by the return treatment pipe 213 and the injection fan 238. At this time, the ammonia flows upwards again to react with dilute sulfuric acid to generate ammonium sulfate. Through the internal circulation of ammonia and the control of the spraying amount of dilute sulfuric acid, stable production of ammonium sulfate is realized, and the generation of ammonium bisulfate due to excessive dilute sulfuric acid is avoided;

[0107] When the ammonia content in the second repeated reaction chamber 203 is low, the concentrated upper exhaust pipe frame 207 in the third repeated reaction chamber 203 is opened at this time, and the tail gas is discharged into the third repeated reaction chamber 203 by cooperating with the injection fan 238. At this time, the ammonia gas still flows upward from the bottom, and the excess dilute sulfuric acid is injected into the third repeated reaction chamber 203 through the dispersion spray head 210, so that the ammonia gas contained therein is fully reacted to generate ammonium bisulfate, and the ammonia gas is detected by cooperating with the gas detector 211, and the internal ammonia gas is circulated by the return treatment pipe 213 and the injection fan 238, so that the ammonia gas is repeatedly reacted and removed. When the ammonia content in the third repeated reaction chamber 203 is lower than the detection value, water is injected into the absorption exhaust chamber 204 through the inlet and outlet matching pipe 216, and the tail gas is injected into the water through the U-shaped injection pipe 214 by opening the linkage control valve 237. By utilizing the characteristics that ammonia gas is easily dissolved in water, the remaining small amount of ammonia gas in the tail gas is fully absorbed, the tail gas is fully purified, ammonium sulfate and ammonium bisulfate are produced, and finally the tail gas is discharged through the inlet and outlet matching pipe 216. By using multi-stage reaction to fully remove ammonia and absorb ammonia, the ammonia in the tail gas is removed, environmental pollution caused by direct discharge of ammonia is avoided, and the polluted gas is converted into nitrogen fertilizer to realize resource recycling;

[0108] The liquid separation exhaust pipe 215 at the position of the repeated reaction chamber 203 is opened by the linkage control valve 237, the ammonium sulfate solution is discharged into the material collection and concentration box 201, and the ammonium bisulfate solution is discharged into the inside of the separation and collection box 222, so as to realize solution discharge treatment. The ammonium sulfate solution is heated by the cold and hot temperature controller 223, and at this time, the gas pressure in the material collection and concentration box 201 is reduced by cooperating with the pressure control treatment pipe 226 and the pressure control pump 227. By using pressure reduction and temperature rise evaporation treatment, the solution is continuously evaporated at an environment of 70°C by controlling the internal pressure, so as to avoid the occurrence of ammonium sulfate tapping due to too high temperature. The switching operation frame 233 is rotated along the lifting load block 231 by cooperating with the switching motor 232, the load crystallization plate 235 is magnetically fixed by the positioning electromagnet 234, the lifting load block 231 and the switching operation frame 233 are lowered by cooperating with the lifting hydraulic cylinder 230, the crystallization treatment rope 236 is placed inside the material collection and concentration box 201, and the material collection and concentration box 201 is sealed by cooperating with the switching operation frame 233 and the load crystallization plate 235, so as to ensure the stability of the pressure control treatment. In the process of heat evaporation, the water vapor evaporated inside is extracted by the exhaust treatment pipe 229 and the injection fan 238, and is injected into the temperature control circulation box 220.

[0109] The solution stirring treatment is promoted by rotating the swing treatment frame 225 driven by the swing motor 224, the solution is fully thermal evaporated, the unsaturated ammonium sulfate solution is converted into the supersaturated ammonium sulfate solution, when the solution is supersaturated, the solution starts to crystallize under the guidance of the crystallization treatment rope 236, at this time, the temperature in the material collection and concentration box 201 is reduced to 10℃ by the cold and hot temperature controller 223, the crystallization efficiency and the crystallization amount are improved, when the crystallization is completed, the load crystallization plate 235 is rotated and moved to the position of the collection treatment box 304 by the lifting hydraulic cylinder 230 and the switching motor 232, the replacement treatment of the crystallization treatment rope 236 is realized, the stability and efficiency of the continuous crystallization are ensured, and the steady production of ammonium sulfate is realized;

[0110] When the crystallization treatment rope 236 accumulated with ammonium sulfate is rotated and moved to the position of the collection treatment box 304, at this time, the collection treatment box 304 is placed at the top end of the in-out positioning plate 302, the collection treatment box 304 and the in-out positioning plate 302 are magnetically attracted and fixed by the fixed electromagnet 303, the in-out electric slide rail 301 drives the in-out positioning plate 302 and the collection treatment box 304 to move, the pressing and stripping treatment plate 308 is moved and inserted into the top of the side end of the crystallization treatment rope 236, the isolation blocking plate 306 is moved by the isolation electric slide rail 305, the collection treatment box 304 is sealed, the pressing and stripping treatment plate 308 is moved along the collection treatment box 304 by the pressing and stripping electric slide rail 307, the ammonium sulfate crystals adhered to the side end of the crystallization treatment rope 236 are pressed and stripped, the ammonium sulfate crystals are pressed into the inside of the collection treatment box 304, after the discharging is completed, the discharging electric slide rail 309 drives the discharging scraper 310 to move along the collection treatment box 304, the ammonium sulfate crystals are pushed into the inside of the dissolution treatment box 311, in the pushing process, the two pressing and sealing covers 312 are respectively rotated along the collection treatment box 304 and the dissolution treatment box 311, finally the ammonium sulfate crystals are pushed into the dissolution treatment box 311, under the action of the spring hinge, the pressing and sealing cover 312 is reset, at this time, the pressing and sealing cover 312 is magnetically attracted and fixed by the sealing electromagnet 313, the steady discharging treatment is realized, the crystallized ammonium sulfate is quickly discharged, and the stability of the material cleaning is improved;

[0111] The hot water with the temperature of 70 DEG C is injected into the dissolving treatment box 311 through the hot liquid injection pipe 314, and the mixing stirring frame 316 is rotated by the dissolving motor 315, so as to push the ammonium sulfate crystals and the hot water to mix and dissolve, and the ammonium sulfate crystals containing part of impurities are dissolved into ammonium sulfate solution. At this time, the ammonium sulfate solution in the dissolving treatment box 311 is extracted by the external discharge pump 318 and the external discharge operation pipe 317, and is injected into the inside of the double-cavity filtrate box 319.
