Detailed Description
In order to make the technical means and functions of the present invention easy to understand, the present invention will be described in detail with reference to the following embodiments and accompanying drawings.
Example (b):
as shown in fig. 1 to 3, the present embodiment provides an adsorption-condensation type water intake from air apparatus 100 for continuously taking water, comprising: the device comprises a shell 1, an air filter screen 2, a separation type adsorption bed 3, an evaporator 4, a condenser 5, a compressor 6, a water receiving tray 7, a water receiver 8, a water filter 9, a motor 10 and a fan 11.
The housing 1 has a cavity therein, and an air inlet 12 is formed at one side thereof.
Airstrainer 2 sets up in air intake 12 for the macromolecular particulate matter in the interception air, in order to avoid producing the harm to the device, also makes the water of preparing cleaner simultaneously.
The separation type adsorption bed 3 is arranged adjacent to the air filter screen 2 and consists of a fin heat exchanger and polyacrylic acid hydrogel which is attached to the fin heat exchanger and used for adsorption, dehumidification and desorption regeneration.
In the embodiment, the polyacrylic acid hydrogel is attached to the surface of the fin heat exchanger through a solution impregnation method, so that the heat transfer and mass transfer performance of the polyacrylic acid hydrogel in the adsorption and desorption processes is enhanced, and the heat and moisture transfer efficiency of the air-material is improved.
Further, the working process of the separation type adsorption bed 3 is as follows, and the working cycle thereof specifically comprises two parts:
(1) and (3) an adsorption dehumidification process: when the wet air flows through the surface of the separation type adsorption bed, the polyacrylic acid hydrogel coated on the fins adsorbs water vapor in the wet air so as to realize the dehumidification effect. Meanwhile, a large amount of adsorption heat is released in the dehumidification process and is absorbed by a cooling medium, namely heat exchange fluid, introduced into the pipe, so that the dehumidification capacity of the adsorbent is maintained.
(2) The desorption and regeneration process comprises the following steps: when the polyacrylic acid hydrogel is adsorbed and saturated, the cooling medium is not introduced into the pipe, but the heating medium, namely the heat exchange fluid, is used for releasing water vapor from the adsorbent under the high-temperature condition and returning to the unsaturated state, so that the regeneration process is completed.
The two processes of adsorption dehumidification and desorption regeneration are continuously circulated, so that the separation type adsorption bed can continuously work, and the cooling medium mentioned in the process is liquid refrigerant.
The evaporator 4 is connected with the separation type adsorption bed 3 through an air duct, so that water, namely condensed water, is produced by liquefying water vapor in the filtered air flowing through the surface of the evaporator, and meanwhile, the evaporator is used for treating low-temperature and low-pressure liquid refrigerant flowing into the evaporator 4 from a capillary tube, so that the low-temperature and low-pressure liquid refrigerant exchanges heat with the filtered air to obtain gas refrigerant.
In this embodiment, the low-temperature low-pressure liquid refrigerant throttled and depressurized by the capillary tube 13 flows into the pipeline of the evaporator 4, exchanges heat with the outside air, and then becomes a gaseous low-temperature low-pressure gas refrigerant, which flows into the compressor. A large amount of heat is absorbed during the vaporization of the liquid refrigerant, causing water vapor in the filtered air flowing over the surface of the evaporator 4 to liquefy and produce water.
The condenser 5 is connected to the evaporator 4 via a capillary tube 13, and processes the liquid refrigerant in cooperation with the evaporator 4 and the capillary tube 13.
In this embodiment, the condenser 5 provides a large space for the high-temperature and high-pressure liquid refrigerant pressurized by the evaporator 4 to dissipate heat, and then returns to the medium-temperature and medium-pressure liquid refrigerant to flow into the evaporator 4 again through the capillary tube 13.
In this embodiment, the capillary tube 13 throttles and reduces the pressure of the high-temperature and high-pressure liquid refrigerant to ensure the pressure difference between the condenser 5 and the evaporator 4; while the gaseous refrigerant in the condenser 5 is discharged at a given high pressure and condensed. In addition, the refrigeration cycle is operated more efficiently by adjusting the flow rate of the refrigerant supplied to the evaporator 4 to accommodate a change in the heat load of the evaporator 4.
The compressor 6 is connected to the evaporator 4 through a suction pipe, and sucks and compresses the gas refrigerant from the evaporator 4 through the suction pipe to obtain a high-temperature and high-pressure gas refrigerant.
In this embodiment, the compressor 6 sucks the low-temperature and low-pressure gas refrigerant from the evaporator 4 through the air suction pipe, compresses the gas refrigerant by the operation of the motor 10, and discharges the high-temperature and high-pressure gas refrigerant to the exhaust pipe to provide power for the refrigeration cycle, thereby realizing the processes of liquefaction, heat release, gasification and heat absorption of gas, and liquefying vapor in the filtered air to obtain condensed water.
The water pan 7 is disposed below the evaporator 4 and is used for receiving the condensed water on the surface of the evaporator 4.
The water receiver 8 is arranged at the bottom of the shell 1, is connected with the water pan 7 through a water pipe and is used for storing condensed water on the surface of the evaporator 4.
The water filter 9 is connected with the water receiver 8 through a water pipe, and the water filter 9 adopts filter media such as activated carbon to remove suspended matters and colloid in water, thereby obtaining drinking water.
In this embodiment, a water pump 14 for delivering water into the water filter 9 is provided between the water filter 9 and the water reservoir 8.
The motor 10 is connected to the compressor 6 for powering the operation of the compressor 6.
The fan 11 is connected with the motor 10, is arranged above the compressor 6 and the motor 10, is on the same horizontal plane with the air filter screen 2, the separation type adsorption bed 3, the evaporator 4 and the condenser 5, and is used for controlling the air to flow in the axial direction, so that the air sequentially passes through the air filter screen 2, the separation type adsorption bed 3, the evaporator 4 and the condenser 5, and the water taking amount is increased.
The separation type adsorption bed 3, the evaporator 4, the condenser 5, the compressor 6, the water receiving tray 7, the water receiver 8, the motor 10 and the fan 11 are all arranged in the cavity of the shell 1, refrigerant pipelines of the evaporator 4, the condenser 5 and the compressor 6 are communicated with the capillary tube 13 and are used for circulating refrigerants, and the refrigerants are directly placed in the pipelines.
As shown in fig. 4, the operation of the adsorption-condensation type water intake device of the present embodiment is as follows:
at night, the air temperature is low and the humidity is high, after the fan 11 is electrified and rotated, the filtered air flows through the separation type adsorption bed 3, at the moment, water vapor in the air is adsorbed by the polyacrylic acid hydrogel attached to the fins and releases adsorption heat, and the heat is taken away by a cooling medium introduced into a copper pipe of the separation type adsorption bed to maintain the adsorption capacity of the polyacrylic acid hydrogel.
In daytime, the air temperature is higher and the humidity is lower, the compressor 6 and the fan 11 are electrified and started, the air filtered by the air filter screen 2 passes through the separating adsorption bed 3 which is desorbing and regenerating, the polyacrylic acid hydrogel attached to the separating adsorption bed 3 releases water vapor under the conditions of high temperature and low humidity, the dew point of the air flowing through the separating adsorption bed 3 is improved, then, a large number of water drops can be formed in the evaporator 4 with the existing refrigerant running, the water drops are dripped into the water receiver 8 at the bottom after dropping into the water receiving tray 7 below the evaporator 4, and the collected water can meet the drinking standard after being disinfected and the water filter 9.
