Embodiment Construction
[0014] as the picture shows:
[0015] The waste water hot water single-channel input path of the present invention is:
[0016] The waste water is sent to the heat exchanger 2 through the filter device 11 and the negative pressure tank 12 from the waste water collection tank 1 through the self-priming water pump 13, and the waste water enters from the waste water inlet 21 of the heat exchanger. There is a temperature difference between the inner wall of the device and the outer wall of the heat exchange copper tube where the cold tap water is located, and the waste hot water releases heat, thereby realizing the first input of heat energy. The cooled waste hot water comes out from the heat exchanger outlet 22 and enters through the waste water pipe. To the waste water inlet of the evaporator 31 of the hot water source heat pump 3, heat exchange is carried out in the heat exchange copper tube of the evaporator with the low-temperature refrigerant outside the tube wall, thereby r...

Abstract
The invention relates to a high-low temperature waste water double-channel heat recovery heat pump system. The high-temperature waste water heat recovery of the system is designed with single-channel The invention relates to a high-low temperature waste water double-channel heat recovery heat pump system. The high-temperature waste water heat recovery of the system is designed with single-channelwaste water input and double-channel heat output. Through operation adjustment, one of two heat double-channel output routes is that running water exchanges heat with waste water through a heat exchanwaste water input and double-channel heat output. Through operation adjustment, one of two heat double-channel output routes is that running water exchanges heat with waste water through a heat exchanger, and after temperature rise, the running water transmits the recovered heat to a heat storage water tank; meanwhile, the other route is that under the automatic control of the system, part of runnger, and after temperature rise, the running water transmits the recovered heat to a heat storage water tank; meanwhile, the other route is that under the automatic control of the system, part of running water is added to enter a condenser of a hot water source heat pump to exchange heat with a refrigerant gas and outputs recovered heat to the heat storage tank. The system radically solves the proing water is added to enter a condenser of a hot water source heat pump to exchange heat with a refrigerant gas and outputs recovered heat to the heat storage tank. The system radically solves the problem of recovery and use of high-temperature waste hot water, recovers heat of high-low temperature waste water with one set of system equipment, protects the heat pump from overheat protection to maiblem of recovery and use of high-temperature waste hot water, recovers heat of high-low temperature waste water with one set of system equipment, protects the heat pump from overheat protection to maintain the normal operation of the system and is wide in application ranges; after heat recovery, the temperature of the wasted water is reduced greatly, and the heat recovery amount and rate of the syntain the normal operation of the system and is wide in application ranges; after heat recovery, the temperature of the wasted water is reduced greatly, and the heat recovery amount and rate of the system are more than 40 percent higher than other heat recovery modes; and the system has the advantages of high efficiency, energy conservation, high input-output ratio, low operation cost, obvious ecostem are more than 40 percent higher than other heat recovery modes; and the system has the advantages of high efficiency, energy conservation, high input-output ratio, low operation cost, obvious economic benefits and so on.nomic benefits and so on.
Description
technical field [0001] The invention relates to waste water heat recovery technology, in particular to a heat pump operation system for waste water heat recovery, in particular to a high and low temperature waste water dual-path heat recovery heat pump system. Background technique [0002] my country has a large population and rapid industrial development, and the discharge of waste hot water for civil bathing and industrial production is considerable. According to incomplete statistics, college students alone discharge 94.43 million tons of waste hot water for bathing every year; factories discharge even more waste water. Some large factories, such as printing and dyeing, chemical, plastic, food and other industries discharge The temperature of waste water is generally above 70°C, and the discharge of high-temperature waste hot water can exceed 10,000 tons per day. It can be seen that my country's waste water resources are extremely rich. Facing the environment of energy po...
