Fig. 1 is the sketch map of auxiliary electrical hot type sea water source heat pump drying system of the present invention;
Among the figure: 1, electric heater 2, first blower fan 3, hothouse 4, second blower fan 5, pretreatment pool 6, first heat exchanger 7, heat pump 8, second heat exchanger 71, compressor 72, evaporation exchanger 73, expansion valve 74, condensation interchanger.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1; The present invention proposes auxiliary electrical hot type sea water source heat pump drying system; Comprise electric heater 1, first blower fan 2, hothouse 3, second blower fan 4, pretreatment pool 5, first heat exchanger 6, heat pump 7 and second heat exchanger 8; Heat pump 7 comprises compressor 71, evaporation exchanger 72, expansion valve 73 and condensation interchanger 74, interconnects through inner loop pipeline each other; Electric heater 1, first blower fan 2, hothouse 3, second blower fan 4, first heat exchanger 6, evaporation exchanger 72, second heat exchanger 8 and condensation interchanger 74 are connected in turn through air pipe line, constitute the air drying cycles; Pretreatment pool 5 is connected with first heat exchanger 6 through water pipe, and the water that first heat exchanger 6 comes out is connected with second heat exchanger 8 through water pipe.
Pretreatment pool 5 supplies cooling water by seawater, to reach stable low temperature supply; Electric heater 1 is that assistant heating is used, and the hot-air that makes out reaches dry temperature index.
The present invention mainly comprises three sub-systems:
Heat pump 7: mainly comprise parts such as compressor 71, condensation interchanger 74, evaporation exchanger 72, expansion valve 73; Get into condensation interchanger 74 behind heat pump fluid to the high temperature high pressure of compressor 71 compressed steam states, energy is emitted in heat pump fluid condensation in condensation interchanger 74, and simultaneously, heat pump fluid becomes liquid heat pump fluid after through condensation interchanger 74; After liquid heat pump fluid entering expansion valve 73 carries out throttling, become heat pump fluid, get into evaporation exchanger 72 again for liquid low-temp low-pressure; Absorb outside energy this moment in evaporation exchanger 72; Liquid heat pump fluid evaporation becomes low-temp low-pressure gaseous state heat pump fluid again, gets into compressor 71 again; Recompress into the steam condition heat pump fluid of HTHP, get into next circulation.
Seawater circulation system: former seawater gets into pretreatment pool 5, and after handling through deposition, decontamination etc., the seawater after the processing gets into first heat exchanger 6, and the dry gas of sending here with second blower fan 4 carries out heat exchange; Because the dry gas temperature is higher, about 55 ℃, and about 15 ℃ of ocean temperature; The two can carry out heat exchange in first heat exchanger 6, dry gas cools off dehumidification in first heat exchanger 6, and temperature is reduced to 35 ℃; And ocean temperature becomes 25 ℃ approximately, and 25 ℃ seawater gets in second heat exchanger 8, at this moment again; The dry gas that becomes 35 ℃ through first heat exchanger 6 has passed through evaporation exchanger 72 again, in evaporation exchanger 72, because the ringing of heat pump 7; Liquid heat pump fluid evaporation process has siphoned away heat from dry gas, cause dry gas to be reduced to about 18 ℃ by 35 ℃, gets in second heat exchanger 8 again; In second heat exchanger 8, the dry gas of 25 ℃ seawater and 18 ℃ carries out heat exchange again, and seawater preheats dry gas, enters marine greatly through the seawater in second heat exchanger 8.
The dry gas circulatory system: about 55 ℃ dry gas that hothouse 3 comes out is carried through second blower fan 4 and in first heat exchanger 6, is carried out heat exchange with seawater, reaches the purpose of cooling dehumidification; The dry gas temperature is reduced to 35 ℃, gets into evaporation exchanger 72 again, and this moment, dry gas was as the origin of heat that evaporates; The heat pump fluid evaporation absorbs heat from dry gas; The dry gas temperature becomes about 18 ℃, and 18 ℃ dry gas gets into again to be handed in second heat exchanger 8, carries out heat exchange again with 25 ℃ seawater; Seawater preheats about 25 ℃ with dry gas; 25 ℃ dry gas gets into condensation interchanger 74 again, energy that condensation is emitted in the absorption condensation interchanger 74, and temperature increases to about 85 ℃ again; 85 ℃ dry gas gets into electrical auxiliary heater 1 again; Temperature further is promoted to about 105 ℃; Reach suitable dry 105 ℃ the dry gas that requires and carry out drying through the 3 pairs of materials of hothouse that deliver into of first blower fan 2, dried gas is through the next circulation of delivering into of second blower fan 4.
Through sea water source heat pump drying system of the present invention, stable drying effect can be provided, to the quality of dry thing effective guarantee is provided.
