Summary of the invention
At above-mentioned the deficiencies in the prior art, but the purpose of this utility model provides a kind of water source heat pump units of automatically backwashing sewage water.This unit can dwindle the heat transfer temperature difference of heat exchanger directly with industrial wastewater or sewage resource and refrigerant heat exchanger direct heat transfer, has improved the efficient of unit, has reduced equipment cost.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
But the water source heat pump units of automatically backwashing sewage water, it comprises the Compression Evaporation condensation unit of being made up of compressor, condenser, expansion valve, evaporimeter and cross valve.Condenser and evaporimeter are water-to-water heat exchanger.Its design feature is to be serially connected with the filter one, water pump, triple valve and the filter two that are connected with source of sewage on the supply channel of described evaporimeter successively.Be serially connected with the motor-driven valve two that is connected with blowoff basin on the water return pipeline of evaporimeter.Between the import and export of evaporimeter, be connected in parallel to differential pressure pickup.Be connected in parallel to motor-driven valve one between the port of export of the junction of filter two and triple valve and motor-driven valve two, another outlet of triple valve is connected with the entrance point of motor-driven valve two.The top of evaporimeter is provided with blow-off pipe, is equipped with motor-driven valve three on the blow-off pipe.
In above-mentioned water source heat pump units, described condenser and evaporimeter adopt the full-liquid type structure, and heat exchanger tube wherein adopts anticorrosion material copper-nickel alloy, and the end cap at condenser and evaporimeter two ends is built-in with the strong metal of reproducibility.
The utility model is compared with prior art owing to adopted above-mentioned structure, has following advantage:
1, can make full use of water resources such as industrial wastewater, sewage, expand the water source scope of water source heat pump system, reduce underground water resource destruction.
2, industrial wastewater and the sewage heat exchanger that can directly enter unit carries out heat exchange, and can not cause corrosion by the heat exchanging device, has reduced heat transfer temperature difference, has improved unit efficiency, and saved equipment cost.
3, the automatic backwash device of heat exchanger side increase can prevent that solid particulate matter forms obstruction in the sewage in heat exchanger.
4, machine set system has been equipped with four-way change-over valve, no matter make refrigeration or heat, the user side water source all need not switch.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the utility model comprises the Compression Evaporation condensation unit of being made up of compressor 1, condenser 2, expansion valve 10, evaporimeter 4 and cross valve 7.Condenser 2 and evaporimeter 4 are the full-liquid type water-to-water heat exchanger, and heat exchanger tube wherein adopts anticorrosion material copper-nickel alloy, and the end cap at condenser 2 and evaporimeter 4 two ends is built-in with the strong metal of reproducibility.Be serially connected with the filter 1, water pump 9, triple valve 6 and the filter 2 8.2 that are connected with source of sewage on the supply channel of evaporimeter 4 successively.Be serially connected with the motor-driven valve 2 5.2 that is connected with blowoff basin on the water return pipeline of evaporimeter 4.Between the import and export of evaporimeter 4, be connected in parallel to differential pressure pickup 3.Be connected in parallel to motor-driven valve 1 between the port of export of the junction of filter 2 8.2 and triple valve 6 and motor-driven valve 2 5.2, another outlet of triple valve 6 is connected with the entrance point of motor-driven valve 2 5.2.The top of evaporimeter 4 is provided with blow-off pipe, is equipped with motor-driven valve 3 5.3 on the blow-off pipe.
When the utility model used, the cryogenic gaseous cold-producing medium was sucked by compressor 1 inlet valve and 1 compression of compressed machine, becomes high-temperature high-pressure refrigerant gas and enters condenser 2 through cross valve 7.Refrigerant gas is with the terminal heating hot water that produces of heat transferred user, the liquid cold-producing medium drying of HTHP filter removal moisture and impurity wherein from condenser 2 comes out becomes the low-temp low-pressure liquid refrigerant after the expansion valve 10 throttling step-downs of flowing through again and enters evaporimeter 4.In evaporimeter 4, the heat that the low-temp low-pressure liquid refrigerant absorbs circulating water constantly evaporates, and has all become the overheated dry saturated steam of low-temp low-pressure when arriving evaporimeter 4 outlets, and the inlet valve of getting back to compressor 1 through cross valve 7 recycles again.Circulating water in the evaporimeter 4 adopts industrial wastewater or sewage, opens water pump 9, and sewage enters evaporimeter 4 through filter 1, water pump 9, triple valve 6 and filter 2 8.2.When motor-driven valve 2 5.2 unlatchings, when motor-driven valve 1 cuts out, the sewage after the heat exchange is discharged to blowoff basin from the return pipe of evaporimeter 4 through motor-driven valve 2 5.2.
