A kind of heat energy exchange recovery device that is used for bath wastewater
Technical field
The present invention relates to the heat recovery technology of the bath wastewater in places such as family, hotel, Hair Salon, particularly a kind of heat energy exchange recovery device that is used for bath wastewater.
Background technology
Bath wastewater is carried out waste heat recovery utilize again, especially utilize bath wastewater that bathing is carried out preheating with running water, can reduce gas, the oil of the power consumption of electric heater or combustion gas, fuel oil, coal-burning heater, the consumption of coal.
At present, similar products like is mounted in the energy-saving base between bathing, it is to adopt a common copper tube as interior pipe, the plastic film capicitor simple and easy double pipe heat exchanger that coiling forms as outer tube, the heat of bath wastewater is recycled, preheating bathing running water is to reach energy-saving effect.But there is following shortcoming in this technology:
(1) in order to improve heat exchange efficiency, have only by lengthening copper tube and bellows (general designation heat exchanger tube) length and solve, the heat exchanger tube length that consumes increases, thereby cause that heat exchanger volume is big, cost is high, and the length of heat exchanger tube is long more, the discharge that provides is more little, and the possibility that the dirt in the sewage is discharged is also more little.
(2) the bushing type interchanger carries out bath wastewater and cold water (running water) exchanges, and needs to increase water pump and realize heat exchange, system complex, cost height with the pressure that improves bath wastewater.
(3) hair in the waste water, dirt enter water pump and heat exchanger easily, cause water pump vane and the easy stall of pump head housing, water pump fault rate height; Simultaneously to have determined to enter the discharge ability of dirt wherein very low for heat exchanger form (heat exchanger tube length is very long, the dirt when bellows is piled up bathing easily as outer tube), and in use for some time, the heat exchange efficiency decay is very fast, causes heat exchange efficiency sharply to reduce.The result is the industrialization difficulty, is unfavorable for promoting the use of.
(4) water pump control need realize by the break-make power supply, inconvenient operation, also dangerous during bathing.
Summary of the invention
At above-mentioned technological deficiency, the object of the present invention is to provide the heat energy exchange recovery device that is used for bath wastewater of a kind of simple in structure, convenient for production, with low cost, stable performance, safety and environmental protection.
