Abstract
The invention discloses a three-level heated waste water waste heat recovery device of a heat-pump water heater. The three-level heated waste water waste heat recovery device comprises a main water collection tank used for collecting heated waste water. A heat exchanger, a first evaporator and a second evaporator are sequentially mounted in the main water collection tank from top to bottom, wherein the second evaporator is mounted in an auxiliary water collection tank which is accommodated in the main water collection tank below the first evaporator. The heat exchanger is in series connection to a water inlet pipe of the heat-pump water heater. The first evaporator and the second evaporator are in series connection. The output end of the first evaporator is connected to an inlet of a compressor of the heat-pump water heater. The input end of the second evaporator is connected to an outlet of a throttle valve of the heat-pump water heater. According to the three-level heated waste water waste heat recovery device, water stored in the auxiliary water collection tank in advance can be utilized as a heat source for the heat-pump water heater to absorb heat when the heat-pump water heater starts to operate. After the operation of the heat-pump water heater is finished, the heat of generated waste hot water is subjected to three-level waste heat recovery through the three-level heated waste water waste heat recovery device, so that the heat of the waste hot water is recovered as much as possible.
Description
Affiliated technical field
The present invention relates to the Teat pump boiler technical field, especially relate to the waste-heat recovery device of the thermal wastewater of Teat pump boiler.
Background technology
Water source heat pump water heater is a kind of device that comes heat hot water from water the inside draw heat.The evaporimeter of water source heat pump water heater is exactly the parts of being responsible for absorbing heat in water.Present employed evaporimeter is mainly recirculation type evaporator and soaks two kinds in long-pending formula evaporimeter.Recirculation type evaporator needs a large amount of water constantly to circulate to provide heat to absorb to evaporimeter; Soaking long-pending formula evaporimeter then needs to soak in pond or the water pot and absorbs heat.All needing to replenish a large amount of water during these two kinds of evaporator operation provides heat to absorb to evaporimeter.If water shortage can cause the Teat pump boiler heat production water yield to reduce, more can cause Teat pump boiler to work when serious.
In addition, waste water and the waste water after the toilet shower after the hair washing of present most of hairdressing place all are directly to emit, and all the waste heat in the waste water are not reclaimed.The water heater that some band excess heat recovery device for shower waste water are arranged, but this retracting device is by behind the interchanger in the running water process wastewater tank, absorbs heat from waste water.But the shortcoming of this waste-heat recovery device: the having a narrow range of temperature of waste water and running water, the waste heat recovery rate is very low.。
Summary of the invention
The problem to be solved in the present invention provides a kind of thermal wastewater waste-heat recovery device of Teat pump boiler efficiently.
The problem to be solved in the present invention, can realize by following technical scheme: a kind of three grades of thermal wastewater waste-heat recovery devices of Teat pump boiler, include in order to collect the main header tank of thermal wastewater, it is characterized in that: heat exchanger is installed in the described main header tank from top to bottom successively, first evaporimeter and second evaporimeter, wherein second evaporimeter is installed in one and is contained in the main header tank and in the secondary header tank of the below of first evaporimeter, heat exchanger is serially connected on the water inlet pipe of Teat pump boiler, first evaporimeter and second evaporimeter serial connection, the output of first evaporimeter is docked with the entrance of the compressor of Teat pump boiler, and the input of second evaporimeter is docked with the outlet of the choke valve of Teat pump boiler.
On the basis of the above, described main header tank is installed in the bottom, bathroom.
The beneficial effect that adopts the present invention to bring: three grades of thermal wastewater waste-heat recovery devices of the present invention can utilize the water of saving in advance in secondary header tank, are used for the thermal source of draw heat as Teat pump boiler when starting working.The spent hot water's who produces after the Teat pump boiler work heat, reclaims spent hot water's heat by three grades of waste heat recoveries as much as possible through the present invention.As seen the present invention can be at the Teat pump boiler prerequisite supplying heat source of starting shooting, make Teat pump boiler that enough heat absorption be arranged when starting working, can after Teat pump boiler work, can constantly from thermal wastewater, absorb heat again, required heat supplement when coming maintaining heat pump water heater operate as normal, thus avoid using a large amount of water that heat is provided.
Description of drawings
Fig. 1 is the structural representation of three grades of thermal wastewater waste-heat recovery devices of Teat pump boiler of the present invention.
The specific embodiment
As shown in Figure 1, a kind of three grades of thermal wastewater waste-heat recovery devices of Teat pump boiler include in order to collect the main header tank 1 of thermal wastewater, and are concrete, and main header tank 1 is installed in the bottom, bathroom.Heat exchanger 2, first evaporimeter 3 and second evaporimeter 4 are installed in the described main header tank 1 from top to bottom successively, wherein second evaporimeter 4 is installed in one and is contained in the main header tank 1 and in the secondary header tank 5 of the below of first evaporimeter 3, heat exchanger 2 is serially connected on the water inlet pipe of Teat pump boiler, first evaporimeter 3 and second evaporimeter, 4 serial connections, the output of first evaporimeter 3 is docked with the entrance of the compressor of Teat pump boiler, and the input of second evaporimeter 4 is docked with the outlet of the choke valve of Teat pump boiler.
When Teat pump boiler is started working, at first, secondary header tank 5 is filled water (when Teat pump boiler uses for the first time), do initial heat source, Teat pump boiler is drawn the heat of the water in the header tank 5, and the water in the storage tank is carried out heat pump to 55 ℃ or higher.When using hot water, 42 ℃ of hot water spray from gondola water faucet, and the spent hot water finally is pooled in the main header tank 1, and the spent hot water at first carries out first order heating to the running water of the heat exchanger 2 of flowing through, water after the heating flows in the storage tank of Teat pump boiler, realizes spent hot water's first order waste heat recovery.The spent hot water flows through behind the heat exchanger 2, and water temperature is down to about 25-30 ℃, then and the refrigeration working mediums in first evaporimeter 3 carry out heat exchange, refrigeration working medium turns back in the compressor of Teat pump boiler after absorbing waste water residual heat, realizes spent hot water's second level waste heat recovery.The spent hot water flows through behind first evaporimeter 3, water temperature is down to about 15-20 ℃, flow at last in the secondary header tank 5 and carry out heat exchange with second evaporimeter, 4 interior refrigeration working mediums, refrigeration working medium turns back in the compressor of Teat pump boiler after absorbing waste water residual heat, realizes spent hot water's third level waste heat recovery.The spent hot water is down to about 5-7 ℃ after through three grades of waste heat recoveries and drains from the bottom of main header tank 1.
