Embodiment
Below in conjunction with present embodiment and accompanying drawing, describe constructional feature of the present utility model and working process in detail.
The constructional feature of present embodiment such as Fig. 1 and shown in Figure 2, distillation case 1 is divided into three chambeies by secondary liquid distributor 3 and air distribution plate 15, is followed successively by spray chamber, evaporation cavity, former water storage chamber from top to bottom.The distillation tank shell is a bilayer structure, and the centre is a lagging material.Spray has liquid distributor 2 and secondary liquid distributor 3 in the chamber, and U type transverse tube water distributor 13 and U type transverse tube 14 are set in the evaporation cavity, the pending former water of former water storage chamber storage.Hot water inlet pipe 19, hot water circulating pump 20, the built-in pipeline 16 of hot water, U type transverse tube water distributor 13, U type transverse tube 14 and hot water outlet pipe 12 constitute hot water circulation loop, the water-in of former water-circulating pump 22 directly communicates with former water storage chamber, and water outlet is linked to each other with liquid distributor 2 by the built-in pipeline 17 of former water.Cooling cylinder 7 linked to each other with distillation case 1 by communicating pipe 4, and prolong is arranged in the cooling cylinder.The inlet pipe 6 of pneumatic pump 9 is inserted in the cooling cylinder, and escape pipe directly communicates with the former water storage chamber top of distillation case 1.The water inlet pipe of water purification transferpump 10 is communicated to the bottom of cooling cylinder.One end of magnetic valve 18 is connected on the hot water inlet pipe 19, and the other end communicates with the former water storage chamber of distillation case 1.Water level sensor 8,22 is installed in respectively on the former water storage chamber of cooling cylinder 7 and distillation case 1.Wash water valve 21 also is equipped with in former water storage chamber bottom at distillation case 1.
The working process of present embodiment is: former water is heated to certain temperature in solar energy collector (or waste heat exchanger), enter U type transverse tube water distributor 13 through the built-in pipeline 16 of hot water inlet pipe 19, hot water circulating pump 20 and hot water, enter U type transverse tube 14 again it is heated, after hot water outlet pipe 12 is flowed back in the solar energy collector (or waste heat exchanger) reheats.Former water in the former water storage chamber in distillation case 1 bottom drives through former water-circulating pump 22, be transported to liquid distributor 2 by the built-in pipeline 17 of former water, behind secondary liquid distributor 3, drop onto equably on the U type transverse tube 14 in the evaporation cavity again, form falling liquid film there and be subjected to thermal evaporation.Unevaporated former water is finally fallen in the former water storage chamber, circulates through former water-circulating pump more next time.When former water forms falling liquid film and flows on U type transverse tube 14, absorb a large amount of heat its hot water in U type transverse tube 14, and produce evaporation and discharge a large amount of water vapour.Pneumatic pump 9 orders about water vapour and enters cooling cylinder 7 through communicating pipe 4, carry out heat exchange with the water coolant in the prolong 5, water vapor condensation, the purified water collecting that produces is in the bottom of cooling cylinder 7, after liquid level arrives certain altitude, water level sensor 8 sends signal to Controlling System 11, and water purification transferpump 10 is opened, and is transported to the water purification storage tank stores and gets up for use.After pure water water level in the cooling cylinder 7 was reduced to a certain degree, water level sensor 8 sent signal to Controlling System 11 once more, and water purification transferpump 10 quits work.Liquid level in the former water storage chamber along with evaporation constantly carry out can be more and more lower, after water level is reduced to a certain degree, water level sensor 23 sends signal to Controlling System 11, magnetic valve 18 is opened, replenish former water to former water storage chamber, after water level was elevated to certain altitude, water level sensor 23 sent signal once more to Controlling System 11, magnetic valve 18 cuts out, and makes former water storage chamber remain certain liquid level.Often opening wash water valve 21 is controlled under certain concentration the former water saltiness in the former water storage chamber.After the former water that temperature is lower carries out heat exchange by prolong 5, enter the former water of solar energy collector (or waste heat exchanger) supplement consumed, reclaimed a large amount of condensation latent heat simultaneously.
