Abstract

The utility model relates to a solar energy seawater desalinating apparatus which mainly provides an apparatus using solar energy and the low temperature energy of seawater in the deep layer to produce fresh water of good quality for desalinating seawater. An evaporator forming an included angle of 30DEG to 40DEG is positioned on the upper part of the apparatus, and a water steam passage, a condenser, a centrifugal air pump, a water supplying and discharging pipeline, a water pump, a water tank and a solar light tracking device are arranged below the evaporator. A majority of the seawater in the deep layer, which is pumped by the water pump, flows through the condenser to reduce the temperature of the blades of the condenser, and a small part of the seawater in the deep layer flows along a staircase-shaped heat collecting plate of the evaporator step by step to be heated and gasified by the solar energy. The air pump continually sucks and discharges air to make negative pressure formed in the evaporator, so that a seawater gasifying process is accelerated and water steam is promoted to flow to the condenser. The water steam is coagulated into fresh water on the surfaces of the blades and the pipelines of the condenser.

Enforcement of the present utility model, more than structure and the circuit shown in each figure be exactly embodiment of the present utility model.Double glazing panel E makes of 5mm toughened glass, wraps sealing material on every side, and the gap is evacuated, and is beneficial to insulation.Vaporizer D, water vapour passage G, condenser H, exhaust-duct L all make by the pressure-resistant seal container standard, and these parts assembling backs form the sealed structure that communicates, and are negative pressure state when equipment work.The angle that vaporizer bottom surface and horizontal plane form during installation should allow vaporizer can accept best lighting effect according to being fixed on after territory of use's latitude adjustment between 30 °-40 °.Vaporizer, upper water box, lower header all should have thermal insulation layer to scatter and disappear to stop heat.After the deep low-temperature seawater is sent into elevated tank 6 by deep sea water extraction pump 4, supply water to sea water desalting equipment by salt water supply house steward 5, the salt water supply house steward is communicated with deep sea water supply pipe M by ring flange N7.The seawater major part condenser H that flows through makes the condenser blade keep very low temperature, again from condenser water shoot O row to the sea.The small part seawater enters upper water box F, the water yield of vaporizer is injected in regulated valve F4 control, allow stepped thermal-arrest plate D3 go up very thin covering one deck seawater, sunlight sees through double glazing panel E and makes seawater heating, gasification, the unnecessary seawater in evaporation back flows into lower header A, and water circulating pump B pumps into upper water box with this part seawater by circulating pipe C.Water vapour arrives condenser H along water vapour passage G, because there are huge temperature head in condenser leaf temperature and water vapour, so water vapour aggegation on blade becomes fresh water, drop onto in the fresh water dish G1, in fresh water output tube I input fresh-water tank 7, the continuous suction of centrifugal air pump makes vaporizer become negative pressure, can reduce the seawater boiling point, promote gasification, and impel water vapour to flow and help being condensed into fresh water to condenser.Photovaristor RT1 equates that with RT2 resistance when being subjected to illumination consistent when the sunlight skew made their light incomes inconsistent, 3 pin current potentials of integrated circuit (IC) 1 departed from, its 1 pin output noble potential makes the G2 triggering and conducting, and relay J gets electric adhesive, the K4 adhesive, drivingmotor Q rotates, driving wheel S moves along guide wheel T, and the drive entire equipment turns to the position over against sunlight, and at this moment RT1 is subjected to light consistent with RT2, the output switching activity of IC1, G2 ends, and J dead electricity K4 disconnects, the electric motor stall.When the sun sets, equipment forwards the final position to, touch limit switch K3, make the K5 adhesive, electric motor is counter-rotating therefore, and driving arrangement resets to starting position, and the K5 dead electricity disconnects when contacting K2, electric motor stops operating, water-level detecting rod in 6 li installations of elevated tank is used for controlling water pump operation, when water level drops to low level detector bar M3 and surfaces, and water pump operation, high-order detector bar M2 touches the water surface when water tank is filled with soon, the output switching activity of IC2, G5 ends, the J2 dead electricity, K6 disconnects, and water pump is out of service.Same water-level detecting rod also is housed in the lower header A, and pilot circuit uses the normally closed interlock of J2, G5 conducting when high-order detector bar is not had by water logging, J2 gets electric, the K6 adhesive, with the water pump of lower header to upper water box.

This reality is made novel single device can satisfy the demand of one family to fresh water.When solving the water supply of community or enterprise, need to build an offshore platform, the vaporizer of every equipment is all towards the solar direction proper alignment at sea on the platform, every deep sea water water-supply pipe M is linked to each other with deep sea water water main 5, every condenser water shoot O is linked to each other with condenser main drain 1, every fresh water output tube is linked to each other with total fresh water pipe 10, forward every equipment to zero position, connect sunlight and follow the trail of circuit interface P1, P2, the vaporizer that starts the back all devices all can slowly turn to over against sun direction of light.
