In the actual cooling process, if only a single air cooling mode is adopted to cool the condensate, the purpose of rapid cooling is difficult to realize, a large amount of energy is consumed in the cooling process, and if only a water cooling mode is adopted to cool the condensate, the high-temperature condensate can enable a large amount of cooling water to be gasified to cause explosion danger, so that the cooling efficiency is improved, and the energy consumption is reduced at the same time. When the method is implemented specifically, cooling water is firstly introduced into the water cooling chamber 110 along the water inlet pipe 180, then the discharge port of the ammonia vapor condensate is communicated with the water inlet end of the first water pipe 130, then the two blowers 140 and the water pump 170 in the air cooling chamber 100 are opened, and the condensate is introduced into the air cooling chamber 100 along the first water pipe 130 under the action of the water pump 170, so that the temperature of the condensate is higher than 100 ℃ generally, the heat of the outer wall of the first water pipe 130 can be taken out along the plurality of air vents 150 through the combined blowing action of the two blowers 140 on the first water pipe 130, the temperature of the first water pipe 130 is further primarily cooled, the temperature of the first water pipe 130 is reduced to be lower than 100 ℃, and the risk of explosion caused by the gasification of the cooling water during water cooling of the condensate is avoided; furthermore, in the air cooling process, because the first water pipe 130 is arranged in an S shape, the contact area between the first water pipe 130 and the air can be enlarged, so that the blower 140 can cool more condensate in unit volume, and further the cooling efficiency of the condensate is improved; when the condensate is initially cooled to below 100 ℃ through the air cooling chamber 100, the condensate is led into the water cooling chamber 110 along the second water pipe 160, so that the temperature is lower than 100 ℃, the risk of explosion caused by the gasification of a large amount of cooling water can be avoided in the process of cooling the condensate by the cooling water in the water cooling chamber 110, the flow direction of the condensate is from top to bottom and the flow direction of the cooling water is from bottom to top in the water cooling process, and then the condensate and the cooling water flow in a counter-current manner, and the purpose of further cooling the condensate is achieved; further, because of the spiral second water pipe 160, the contact area between the second water pipe and the cooling water can be increased, and the heat exchange efficiency of the condensate and the cooling water can be increased, and the cooling efficiency can be increased.

The thermometer 200 is arranged at the top of one side, close to the water outlet end of the first water pipe 130, of the air cooling chamber 100, the probe 210 extends into the condensate, the temperature of the condensate in the air cooling chamber 100 can be observed on the dial plate of the thermometer 200 at any time through measurement of the probe 210, if the temperature is lower than 100 ℃, the condensate can be smoothly discharged out of the air cooling chamber 100 along the first water pipe 130, and if the temperature is not lower than 100 ℃, the first water pipe 130 needs to be continuously blown until the temperature of the condensate is qualified.

Further, when the temperature measured by the thermometer 200 is not acceptable, i.e. greater than 100 ℃, it cannot flow into the water cooling chamber 110 along the first water pipe 130, and for this reason, the water outlet end of the first water pipe 130 is provided with a valve 220.
