Referring to fig. 7, the desalination apparatus further includes an air supply channel 71, a heater 72, an evaporator 73, a compressor 74, a condenser 75, a cooling fan 76 and a humidifying nozzle 77, wherein the air supply channel 71 is disposed in the interlayer of the main body 1, the heater 72 is disposed on the air supply channel 71, one end of the evaporator 73 is connected with the condenser 75, the other end of the evaporator 73 is connected with the compressor 74, the cooling fan 76 is disposed on the side of the condenser 75, the humidifying nozzle is disposed on the inner wall of the main body, and the humidifying nozzle is connected with a water pump, specifically, the evaporator 73, the compressor 74, the condenser 75 and the cooling fan 76 may be disposed beside the water outlet pump 42 and the water pump 52 shown in fig. 3.
The compressor 74 is a driven fluid mechanical device that lifts low pressure gas to high pressure gas and is the heart of the refrigeration system. The refrigerating cycle of compression, condensation (heat release), expansion and evaporation (heat absorption) is realized by sucking low-temperature and low-pressure refrigerant gas from the air suction pipe, driving the piston to compress the refrigerant gas through the operation of the motor, and discharging high-temperature and high-pressure refrigerant gas to the air discharge pipe to provide power for the refrigerating cycle.
The condenser 75 is a component of the refrigeration system, which is a type of heat exchanger, that converts a gas or vapor into a liquid, and transfers heat from the tubes to the air in the vicinity of the tubes in a rapid manner. The gas passes through a long tube (typically coiled into a solenoid) to dissipate heat into the surrounding air, and metals such as copper, which are highly thermally conductive, are commonly used to transport vapors. In order to improve the efficiency of the condenser, a heat radiating fin with excellent heat conduction performance is often attached to a pipeline, so that the heat radiating area is enlarged, the heat radiation is accelerated, the air convection is accelerated by a fan, and the heat is taken away. The condenser operation is exothermic, so the condenser temperature is high.
The evaporator 73 is an important part in four refrigeration components, and the condensed liquid (refrigerant) body with low temperature, which is compressed and liquefied, passes through the evaporator to exchange heat with the outside air, so that the gas absorbs heat, and the temperature of the surrounding medium is reduced, so that the refrigeration effect is achieved.
The device also comprises a temperature sensor (not shown) and a humidity sensor (not shown), wherein the temperature sensor and the humidity sensor are arranged on the side edge of the placing frame (2) and are electrically connected with the controller 6;
setting the ambient temperature in the main body to 20 ℃ +/-2 ℃ on the control panel 61, setting the ambient humidity in the main body to be less than 45%RH, and controlling the heater 72 to work when the temperature sensor detects that the temperature in the main body is lower than 18 ℃; when the temperature sensor detects that the temperature in the main body is lower than 22 ℃, the evaporator 73, the compressor 74, the condenser 75 and the cooling fan 76 can be controlled to operate; the humidifying nozzle 77 is controlled to operate when the humidity sensor detects that the ambient humidity is less than 45% rh, and the heater 72, the evaporator 73, the compressor 74 and the condenser 75 are controlled to operate together when the humidity sensor detects that the ambient humidity is greater than 45% rh.
After the desalting treatment in the bottle can is completed, the outer surface of the ceramic can be desalted by adopting a pulp wet dressing method, namely, a piece of paper towel Zhang Fu is taken off.
It is worth to say that when the desalination environment is near the sea, for example, a museum, many salt mist exists in the air, and the salt mist also can be settled in the desalination pond, and the closed box body is designed, so that the environment is controllable, and the interference of the salt mist is avoided.
The foregoing examples illustrate only a few embodiments of the utility model and are described in detail herein without thereby limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
