Description
Technical field
The present invention relates to a kind of mutual adsorbed solar wind energy device for fetching water from air, belong to solar wind-energy adsorption air water-intaking device technical field.
Background technology
Utilize regenerative resource from air, to obtain aqueous water, the area deficient for freshwater resources is very valuable.In several kinds of methods in the cards; The solar energy absorption method is one of feasible way; The technical scheme of existing adsorption-type solar water generator with air as raw material; Chinese patent (application number) 01113489.5, Chinese patent (application number) 200410053390.5, Chinese patent (application number) ZL02261055.3 are the main bodys of adsorbent bed being made solar energy collector; Sunlight will be positioned over the adsorbent heating in the solar energy collector, and steam working medium behind the desorption (claiming desorption again), is liquefied as aqueous water at condensing apparatus and flows into water storing tank from the adsorbent.At night, the adsorbent in the heat collector cools off naturally with atmospheric environment and begins the steam in the absorbed air, and up to the maximum moisture adsorption equilibrium value of adsorbent, 24 hours is a cycle period.Chinese patent (application number) 200610013085.2 adsorbent beds are also made solar energy collector; Adsorbent bed, condensing apparatus, absorption working pair reservoir are formed closed system; The solar energy heating on daytime makes the Working medium gas desorption of adsorbent bed absorption, in condensing apparatus liquefaction and deposit reservoir in.Night, adsorbent bed cooled off naturally, and absorption is lowered the temperature the gasification of reservoir working medium to adsorbent to working medium, free airsetting knot water generates is arranged on the reservoir outer wall and obtain water.The advantage of these technical schemes is " not electricity consumption does not have transmission device ", and is simple in structure, cheap, but the solar energy efficiency of producing drinking water is very low.The technical scheme of Chinese patent (application number) 200610025350.9 is in the absorption room, to place the adsorbent bed assembly that a plurality of inlet tube and outlet tubes are in parallel, and assembly is determined by water withdrawal.Daytime, the hot water of solar energy collector heated these assemblies simultaneously, and the steam desorption gets into water receiver in condensing apparatus liquefaction, begins the process of steam in the absorbed air night, strengthens circulation of air with blower fan.The solar energy efficiency of producing drinking water is also lower.
Existing adsorption-type solar water generator with air as raw material efficiency of producing drinking water is low, and the complete machine structure technical scheme also generally lacks solar wind-energy resource complementation comprehensive utilization, microelectronics observation and control technology are combined to the characterization of adsorption technical data with adsorbent working medium.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art scheme; A kind of mutual adsorbed solar wind energy device for fetching water from air is provided; With solar energy, the heat source water of wind energy complementary energy conversion and the cooling water that matches; Under single-chip microcomputer industry control unit commands for controlling, carry out the continuous circular flow of heat supply/desorption, cooling/absorption alternately according to 3 adsorbent bed unit of driven by program, the solar panel electric supply installation provides electrically-controlled component electric power.The utility model technical scheme can improve regenerative resource air water-intaking efficient significantly, from air, obtains more fresh water, can comparatively fast form the standardization approved product and invest market.
The adsorbent bed unit is the casing that adsorbent is housed, and each face of casing has the polyurethane foam plastic insulation layer, and is heat insulation with the external world.Be laid with water pipe in the adsorbent bed unit to adsorbent heating, cooling; With samely go out, incoming interface joins with heat source water or cooling water loop; Be provided with in the pipeline by the electromagnetic valve and the micro pump of single-chip microcomputer industry control unit program control, with heat source water and cooling water respectively with the heat supply of each adsorbent bed unit or cool off water inlet pipe and water outlet pipe interface UNICOM.The adsorbent space, adsorbent bed unit that one group of electromagnetic valve by single-chip microcomputer industry control unit program control will be in heat supply/desorption working hour connects composition and the isolated closed-circuit system of atmosphere with condensing apparatus, water storage tank; The adsorbent space, adsorbent bed unit that will be in cooling/absorption working hour connects the open system of forming with the atmosphere communications and liaison with ventilating pipe.One group of temperature control water pump; The hot water of solar energy collector and the generation of wind energy wind-heat converter is stored in the good thermal source water tank of thermal insulation jointly; Solar radiant energy and wind energy convert heat energy into, are the heat source water of heat transfer medium with water, and the heat energy of adsorbent desorption is provided to 3 independent of each other (or more than 2) adsorbent bed unit A1, A2, A3... according to program; With 3 in accompanying drawing is that example is at first to the A1 heat supply; Electromagnetic valve is during with heat source water tangential A1 unit heating, and with adsorbent space tangential condensing apparatus, the water storage tank of A1, form and atmosphere isolated closed-circuit system synchronously by the adsorbent space of A1 and condensing apparatus, water storage tank for another electromagnetic valve.The water conservancy project matter desorption that heat supply heats the adsorbent of A1 and will adsorb, the supersaturated vapor of desorption get into the liquefaction of condensing of wing formula condensing apparatus, liquefaction water inflow water storage tank.The latent heat of vaporization on the condensing apparatus can reclaim hot water or discharging directly into atmosphere with interchange of heat.
When after heat supply/desorption period, section finished of A1 unit, electromagnetic valve is with the A2 heat supply of adsorbent bed unit, heat source water tangential, and another electromagnetic valve breaks off condensing apparatus, water storage tank and A1 synchronously, is connected with the adsorbent space of A2.The adsorbent space of A2 and condensing apparatus, water storage tank are formed and the isolated closed-circuit system of atmosphere.At this moment A1 unit is by electromagnetic valve tangential cooling water source, another electromagnetic valve synchronously with the adsorbent space of A1 through ventilating pipe and atmosphere, the A1 adsorbent space that is in cooling/absorption working condition changes into the open-circuit condition with the atmosphere communications and liaison.Provide the cooling water of atmospheric environment temperature to make the A1 absorbent force fast cooling by cooling water tank, A1 gets into the absorption period, and the adsorbent in the absorption bed begins steam in the rapid absorbed air, prepares the moisture content of capacity for next desorption.
After A2 unit heating/desorption period finishes, next A3 unit, heat source water tangential; Tangential, A2 unit cooling water gets into the absorption working condition period, also opens circuit with condensing apparatus, water storage tank synchronously and change into the open circuit adsorbed state with the atmosphere couplet in the adsorbent space of A2; The adsorbent space of A3 and condensing apparatus, water storage tank are formed and the isolated closed-circuit system of atmosphere.After heat supply/desorption period of A3 finishes, begin the next samsara cycle, heat source water is switchback A1 again; A3 tangential cooling water source, A3 units synchronization get into the operating mode period of cooling/absorption, and the adsorbent space of A3 also synchronous and condensing apparatus, water storage tank open circuit and change into the open circuit adsorbed state with the atmosphere couplet.Made adsorbent bed unit A1, A2, A3 carry out the continuous circular flow of heat supply/desorption/condensation/water storage, cooling/absorption alternately by the electromagnetic valve of single-chip microcomputer industry control unit program commands for controlling and micro pump in the pipeline.
