In one embodiment, the heat transfer container 242 is a tank independently installed and stores a fluid for transferring heat, and in another embodiment, the heat transfer container 242 may directly use the distilled water tank, that is, distilled water obtained by condensation is used as a heat transfer medium in the heat transfer cavity. The auxiliary heat radiator 243 is connected to adjust the temperature of the heat-conducting medium in the heat-conducting container 242, so as to change the heat in the whole system, and if the temperature in the system is too high, the auxiliary heat radiator 243 is used to lower the temperature of the heat-conducting medium to a set value and then inject the heat-conducting medium into the heat-conducting cavity, and at this time, the heat or cold in the heat-conducting cavity is conducted to the evaporation plate 120 through the outer wall of the metal water collecting pipe 240 and then conducted to the inside of the evaporation tank 110. In practice, the auxiliary radiator 243 may adopt a natural cooling heat dissipation manner, that is, a capillary tube and a circulation pump, so that the heat-conducting medium in the heat-conducting container 242 exchanges heat with the ambient air; an active cooling and heat dissipation mode may also be adopted to control and connect the auxiliary heat sink 243 with the control element, such as a compressor, a heat dissipation fan, and the like, which is specifically referred to as an air conditioner cooling structure and is not described herein again.
Based on the above technical scheme, when the air flow normally passes through the water collecting chamber 210, the heat conducting cavity 241 is not filled with the heat conducting medium, and most of the water vapor is absorbed by the water absorbing material 232; when the water absorbing material 232 absorbs water and is saturated, the heat conducting medium is injected into the heat conducting cavity 241, and at the moment, the cold energy generated by the evaporation of the sewage in the evaporation tank 110 is conducted to the inner side wall of the metal water collecting pipe 240, so that the condensation of the water vapor in the water collecting chamber 210 is facilitated, and meanwhile, the heat in the water collecting chamber 210 is conducted to the evaporation plate 120 in the evaporation tank 110, so that the evaporation of the sewage is facilitated. The auxiliary radiator 243 discharges the excessive heat of the whole device to the external space as required, and controls the temperature of the whole system.
In order to control the operation state of the water collecting chamber 210, i.e., when the water recovery action of the water absorbent material 232 is performed, the humidity detecting member 800, such as a humidity sensor, is disposed at the airflow outlet of the water collecting chamber 210. When the humidity value of the air collected by the humidity detection part 800 is within the set range, the control part starts the air circulation assembly 220, and the water absorption part 230 absorbs the water vapor in the air flow; when the humidity value of the air collected by the humidity detection part 800 exceeds the set range, that is, the water absorption material 232 does not absorb water after absorbing water to saturation, and the humidity in the air flow increases, at this time, the control part turns off the air circulation component 220 and controls the water collection component 300 to start a water discharge action, and the water absorption material 232 is heated by the electric heating element to discharge the water therein.
In the embodiment of the application, the control element may be implemented by a single chip microcomputer control module or a PLC control module loaded with a set program, the humidity sensor collects and outputs a humidity detection signal and then transmits the humidity detection signal to the control element, and the control element determines a range in which the humidity detection signal is located based on the built-in program and outputs a corresponding control signal. Meanwhile, the control element outputs various control signals based on the built-in program to control parameters of various functional components, such as speed, flow and the like of the sewage circulation component 130 and the air circulation component 220.
Because the landfill leachate contains oily substances, in the evaporation tank 110, in order to reduce the phenomenon that water droplets in the airflow entrain oil and slag to enter the water collecting chamber 210 and prolong the service life of the water absorbing material 232, preferably, a cyclone separation chamber 223 structure is arranged at one end of the circulating air pipe 221, which is positioned at the top of the evaporation tank 110, and fine sewage particles mixed in the airflow are separated back to the evaporation tank 110 again by using the centrifugal action of the cyclone separation chamber 223.
Meanwhile, in order to reduce the generation of water droplets while securing a sewage evaporation area, the evaporation plate 120 is provided as a corrugated plate and the surface of the evaporation plate 120 is provided with a hydrophilic cotton layer 121 or a hydrophilic coating layer.

According to the scheme, when the sewage is fully dispersed and the contact area between the sewage and the air is increased, the sewage is prevented from rebounding and splashing after contacting the evaporation plate 120, so that the generation of water mist in the top area of the evaporation tank 110 is reduced, and the probability that the pollutants are wrapped by the small water drops and enter the water collecting chamber 210 is reduced.
In order to block the air circulation loop and ensure that the vapor evaporated by the water absorbing material 232 does not return to the evaporation tank 110 when the water absorbing material 232 in the water collection chamber 210 is saturated with water, it is further preferable that the air circulation tube 221 is provided with an electric valve 2210 for controlling the communication state between the evaporation tank 110 and the water collection chamber 210, and the electric valve 2210 can be an electric butterfly valve which is in control connection with a control part.

When the temperature of the air flow or the sewage is too high, the survival and propagation of aerobic microorganisms in the sewage are not facilitated, at this time, the auxiliary air inlet pipe 2214 is gated by the gating valve 2215 to stop aeration, or the scavenging valve 2211 is opened, new air with lower temperature and higher oxygen content is introduced into the evaporation tank 110, at this time, the main air inlet pipe 2213 is gated to increase the oxygen content for sewage aeration and control the temperature of the sewage at the same time. In certain embodiments, an oxygen content detecting device may be disposed in the evaporation tank 110 and outputs a detection signal to a control member, which controls the operation of the aforementioned ventilation valve 2211 according to the oxygen concentration in the evaporation tank 110.
Based on the above technical solution, the air exchange valve 2211 can be used to absorb the air in the external environment, and the temperature and oxygen content of the air flow in the evaporation tank 110 can be adjusted; when the temperature is in a proper range, the control element gates the main air inlet pipe 2213 so that oxygen in the circularly flowing air can be further dissolved into the sewage at the bottom of the evaporation tank 110, the sewage to be treated in the evaporation tank 110 is further treated by a biological method, the amount of pollution components such as grease in the sewage is reduced, and the sewage treatment effect is improved.
