Abstract
The utility model relates to a heat pump type sea water desalination device which comprises a heat pump system and a sea water separation system. The heat pump system comprises a compressor, a first stage condenser, a second stage condenser, a throttle and an evaporator. The sea water separation system comprises a closed sea water tank which is provided with an air pumping pipe at the top. A vacuum pump is equipped to the air pumping pipe. The first stage condenser is immersed into the sea water tank. A discharging pipe of the vacuum pump sequentially passes through the second stage condenser and the evaporator. The water vapor in the pipe is cooled to liquid fresh water after heat exchange with the second stage condenser and the evaporator. The sea water tank is provided with a water inlet valve and a water outlet valve. The heat pump type sea water desalination device has the advantages of simple structure and convenient operation. The fresh water separation with the heat pump has lower energy consumption compared with the traditional sea water desalination technique. The heat pump type sea water desalination device is suitable for using on land as well as using on the mobile devices of ship, etc.
Description
Technical field
The utility model relates to a kind of sea water desalinating plant, a kind of heat-pump-type sea water desalinating plant.
Background technology
Traditional desalination technology mainly contains distillation method, cold method, electroosmose process and ion exchange method etc.Distillation method is that steam is met condensation and become water with seawater heating becoming steam, and most of impurity can not be vaporized, and obtains purified water; Cold method is that the principle of utilizing the solubleness of salt in water to reduce with water temperature is frozen cooled with seawater and reduced the saliferous rate in the water, above-mentioned the whole bag of tricks all exists desalination efficient low, the shortcoming that energy consumption is high, and also there are shortcomings such as technical difficulty height, complicated operation at present in electroosmose process and ion exchange method.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, heat-pump-type sea water desalinating plant that energy utilization rate is high, easy to operate.
The technical scheme that the utility model adopted is:
A kind of heat-pump-type sea water desalinating plant, comprise heat pump and seawater separation system, described heat pump comprises compressor, first step condenser, second stage condenser, current regulator and vaporizer, described seawater separation system comprises airtight seawater groove, seawater groove top is provided with extraction pipe, extraction pipe is equipped with vacuum pump, first step condenser immerses in the seawater groove, the discharge line of vacuum pump is successively through second stage condenser and vaporizer, water vapor in the pipeline carries out the heat exchange postcooling with second stage condenser and vaporizer and becomes liquid fresh water, and the seawater groove is provided with water intaking valve and water discharge valve.
The beneficial effects of the utility model are: the design utilizes first step condenser that the seawater in the seawater groove is heated, utilize vacuum pump that the seawater groove is vacuumized again, make the fresh water in the seawater be extracted out with the form of water vapor, water vapor is discharged through liquefy fresh water after the cooling of second stage condenser and vaporizer again, this apparatus structure is simple, easy to operate, specific energy consumption is lower mutually with traditional desalination technology to utilize heat pump to come separate fresh, this device is not only applicable to the land, and applicable on the mobile equipments such as seagoing vessel.
