Description of drawings
Accompanying drawing is a structural front view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Shown in accompanying drawing, the present invention includes electric smelter, condenser, softening water tank and radiating tube, the body of heater periphery of electric smelter 12 has interior recirculated water chuck 11, the water inlet pipe 10 of interior recirculated water chuck 11 links to each other with the water side of condenser 2, water pump 8 is housed on the water inlet pipe 10, condenser 2 places pond 1, the other end of condenser 2 is connected with softening water tank 5 through the downcomer 4 of softening water tank, the outlet pipe 13 of the interior recirculated water chuck 11 of electric smelter and second control valve 14, the 3rd control valve 15 1 ends link to each other, second control valve, 14 other ends link to each other with the backwater end of softening water tank 5 and the water side of radiating tube 16 through return pipe 7, the 3rd control valve 15 other ends link to each other with the water inlet end of radiating tube 16, and radiating tube 16 places in the workshop 17.
In order to guarantee result of use, on the described water inlet pipe 10 water knockout drum 9 is housed; First control valve 3 is housed on the downcomer 4 between described condenser 2 and the softening water tank 5, and is connected with water pump 8 on the water side of condenser; On the described softening water tank 5 blast pipe 6 is housed.
By said structure as can be seen, the present invention includes electric smelter, water softening system, the demineralized water cooling system, bootstrap system, UTILIZATION OF VESIDUAL HEAT IN mainly is to be used for improving room temperature winter, and directly get back to melded system and handle summer, uses after the cooling system cooling again.Specifically:
Winter: first control valve 3 and second control valve 14 are closed, the 3rd control valve 15 is opened, after demineralized water gets off from softening water tank 5, promote via water pump 8, enter recirculated water chuck 11 in the electric smelter after water knockout drum 9 shuntings, body of heater is lowered the temperature, flow of hot water after coming out from outlet pipe 13 in the cooling back is through the radiating tube 16 of job shop, improve the job shop room temperature, the water after coming out from radiating tube 16 comes back to softening water tank 5 again, enters circulation next time.
Summer: first control valve 3 and second control valve 14 are opened, the 3rd control valve 15 cuts out, after demineralized water gets off from softening water tank 5, after condenser 2 coolings, promote by water pump 8, enter recirculated water chuck 11 in the electric smelter after water knockout drum 9 shuntings, body of heater is lowered the temperature, water after coming out from outlet pipe 13 in the cooling back comes back to softening water tank 5, enters circulation next time.
