[0032] Condensing mechanism, condensing mechanism is arranged at the front end of conveying pipe 2;

[0033] Wherein, condensing mechanism includes condensing pipe 3, the inside of the outer surface of condensing pipe 3 is fixedly sleeved with the front end of conveying pipe 2, the inside of condensing pipe 3 is movably sleeved with cooling pipe 4, the outer surface of condensing pipe 3 is fixedly installed with water tank 5, the inside of the left side of water tank 5 is fixedly sleeved with the outer surface of both ends of cooling pipe 4, one end of cooling pipe 4 is provided with water pump 6, the bottom end of water pump 6 is fixedly connected with the inside of water tank 5, the inside of condensing pipe 3 is fixedly installed with air inlet pipe 7, the outer surface of air inlet pipe 7 is movably sleeved with cooling pipe 4, the bottom end of 3 is fixedly sleeved with collection tank 8, the inside of the bottom end of collection tank 8 is fixedly sleeved with backflow pipe 9, valve 10 is provided on backflow pipe 9.

[0034] Because the inside of condensing pipe 3 is provided with cooling pipe 4, when ammonia and water vapor enter the inside of condensing pipe 3 from conveying pipe 2, it will contact with cooling pipe 4, at this time, the inside of cooling pipe 4 will absorb the temperature of water vapor to make water vapor condense into water droplets rapidly, then these water droplets will slide down and fall into the inside of collection tank 8 to complete collection, when valve 10 is opened, at this time, the water in the inside of collection tank 8 will flow back to cooling tower through backflow pipe 9, to achieve the effect of saving system water and reducing water consumption, at the same time, ammonia gas will move to the inside of air inlet pipe 7, when water pump 6 operates, at this time, the cooling liquid in the inside of water tank 5 will flow to the inside of cooling pipe 4, to ensure the condensation efficiency of cooling pipe 4 to water vapor.

[0035] Wherein, the back of water tank 5 is fixedly installed with fixed frame 23, the back of fixed frame 23 is fixedly connected with the front of hydrolysis box 1.

[0036] Because of the design of fixed frame 23, it can play a good supporting role for water tank 5.

[0037] Wherein, the top of condensing pipe 3 is fixedly installed with vertical pipe 11, the top of the outer surface of vertical pipe 11 is fixedly sleeved with gas conveying pipe 12.

[0038] Due to the design of the vertical pipe 11 and the gas conveying pipe 12, the ammonia gas inside the condensing pipe 3 can be conveyed.

[0039] The inner part of the vertical pipe 11 is fixedly sleeved with a sleeve pipe 13, the inner part of the sleeve pipe 13 is respectively provided with a vertical groove 14 and a limiting groove 15, the inner part of the limiting groove 15 is slidably connected with a moving block 16, the outer surface of the moving block 16 is fixedly installed with a stop block 17, and the outer surface of the stop block 17 is movably sleeved with the inner part of the sleeve pipe 13.

[0040] Due to the design of the limiting groove 15, the movement of the moving block 16 is limited, so that the stop block 17 can only drive the moving block 16 to move upward along the inner part of the limiting groove 15. Due to the design of the stop block 17, the inner part of the sleeve pipe 13 can be well shielded. Due to the design of the vertical groove 14, when the stop block 17 moves upward, the vertical groove 14 is affected and the shielding of the inner part of the sleeve pipe 13 is removed, so that the ammonia gas inside the condensing pipe 3 can flow to the inner part of the gas conveying pipe 12 through the vertical groove 14.

[0041] The top end of the stop block 17 is fixedly installed with a vertical rod 18, the outer surface of the vertical rod 18 is movably sleeved with a fixed block 19, and the outer surface of the fixed block 19 is fixedly connected with the inner part of the vertical pipe 11.

[0042] When the stop block 17 moves upward, the vertical rod 18 will move upward along the inner part of the fixed block 19. Due to the design of the fixed block 19 and the vertical rod 18, the stop block 17 can move upward more stably.

[0043] The bottom end of the fixed block 19 is fixedly installed with a spring 20, and the bottom end of the spring 20 is fixedly connected with the top end of the stop block 17.

[0044] When the stop block 17 moves upward, the spring 20 will be compressed. Due to the design of the spring 20, the movement of the stop block 17 can be reset well.

[0045] The inner part of the top end of the hydrolysis box 1 is fixedly sleeved with a liquid inlet pipe 21, the inner part of the hydrolysis box 1 is provided with a heating wire 22, and the two ends of the heating wire 22 are fixedly sleeved with the inner part of the right side of the hydrolysis box 1.

[0046] Due to the design of the liquid inlet pipe 21, the operator can pour the urea solution into the inner part of the hydrolysis box 1 through the liquid inlet pipe 21. Due to the design of the heating wire 22, the urea solution can be heated.

[0047] The top end of the water tank 5 is fixedly installed with a heat dissipation fin 24, the inner part of the heat dissipation fin 24 is fixedly sleeved with a heat absorbing copper pipe 25, and the heat absorbing copper pipe 25 extends to the inner part of the water tank 5.

[0048] Due to the design of the heat-absorbing copper pipe 25, the heat inside the water tank 5 can be absorbed, and due to the design of the heat-dissipating fins 24, the heat absorbed by the heat-absorbing copper pipe 25 can be efficiently dissipated.

[0049] The top end of the water tank 5 is fixedly installed with a support 26, the top end of the support 26 is fixedly installed with a motor 27, and the other end of the output shaft of the motor 27 is fixedly sleeved with a rotating shaft 28.

[0050] When the motor 27 operates, the rotating shaft 28 will rotate at this time.

[0051] The bottom end of the outer surface of the rotating shaft 28 is fixedly sleeved with a fan blade 29, and the fan blade 29 is located above the top end of the heat-dissipating fins 24.

[0052] When the rotating shaft 28 rotates, the fan blade 29 will rotate, and due to the design of the fan blade 29, when the fan blade 29 rotates, the heat-dissipating fins 24 will be blown, so that the heat dissipation efficiency of the heat-dissipating fins 24 can be improved.

[0053] The working principle and use process of the utility model:

[0054] First, the operator pours the urea solution into the inside of the hydrolysis tank 1 from the liquid inlet pipe 21, then the operator starts the heating wire 22, then the urea solution in the hydrolysis tank 1 is evaporated into ammonia and water vapor, at this time the ammonia and water vapor enter the inside of the condensing pipe 3 through the conveying pipe 2, at this time the water vapor contacts the cooling pipe 4 in the condensing pipe 3, then the operator starts the water pump 6, at this time the water pump 6 sucks the cooling liquid in the water tank 5 and transports it into the inside of the cooling pipe 4, at this time the water vapor in the condensing pipe 3 contacts the cooling pipe 4 and is quickly condensed into water droplets, then the water droplets slide downward to the inside of the collecting tank 8 under the influence of gravity to complete collection, when the operator opens the valve 10, at this time the water in the collecting tank 8 flows back to the inside of the cooling tower through the backflow pipe 9, so that the function of quickly condensing and recycling water vapor is achieved, and at the same time the ammonia gas enters the inside of the gas inlet pipe 7;

[0055] When the pressure inside the air inlet pipe 7 increases due to the accumulation of too much ammonia, the block 17 will move under the action of ammonia pressure at this time. The moving block 16 will move along the inside of the limiting groove 15 under the driving of the block 17. Due to the design of the limiting groove 15, the movement of the moving block 16 will be limited so that it can only move up and down. At this time, the moving block 16 will move upward under the driving of the block 17. At the same time, the block 17 will drive the vertical rod 18 to move upward along the inside of the fixed block 19. Due to the design of the vertical groove 14, when the block 17 moves upward, it cannot block the inside of the sleeve 13, so that the ammonia can flow through the vertical groove 14 to the inside of the gas conveying pipe 12, thereby achieving the effect of automatically conveying ammonia. In this process, the spring 20 will be compressed by the block 17. Due to the elastic force of the spring 20, it will have a good resetting effect on the movement of the block 17 as a whole. Therefore, when the ammonia pressure inside the condensing pipe 3 decreases, the vertical rod 18 will drive the block 17 to move downward for resetting, thereby being able to block the inside of the sleeve 13 again.

[0056] Since the cooling liquid inside the cooling pipe 4 can absorb the heat of the inner wall of the condensing pipe 3, when the high-temperature cooling liquid inside the cooling pipe 4 flows back to the inside of the water tank 5, it will increase the temperature of the cooling liquid inside the water tank 5. Due to the design of the heat-absorbing copper pipe 25, it can efficiently absorb the temperature of the cooling liquid inside the water tank 5. Then the heat-absorbing copper pipe 25 will conduct heat to the heat dissipation fins 24. Due to the design of the heat dissipation fins 24, it can greatly increase the heat dissipation area and achieve high-efficiency heat dissipation effect through heat convection. Then the operator starts the motor 27. At this time, the shaft 28 will drive the fan blade 29 to rotate. Due to the design of the fan blade 29, when the fan blade 29 rotates, it will blow the heat dissipation fins 24, thereby improving the heat dissipation efficiency of the heat dissipation fins 24 to achieve the function of rapidly cooling the cooling liquid.
