Abstract
The utility model discloses a three-stage hot wastewater afterheat recovery device for a heat pump water heater. The device comprises a main water collection tank for collecting hot wastewater, wherein a heat exchanger, a first evaporator and a second evaporator are sequentially arranged in the main water collection tank from top to bottom; the second evaporator is arranged in an auxiliary water collection tank, and the auxiliary water collection tank is accommodated in the main water collection tank, and is positioned below the first evaporator; the heat exchanger is connected in series with a water inlet pipe of the heat pump water heater; the first and second evaporators are connected in series; 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 throttling valve of the heat pump water heater. According to the three-stage hot wastewater afterheat recovery device, water pre-stored in the auxiliary water collection tank can be used as a heat source for the heat absorption of the heat pump water heater when the heat pump water heater starts working, and the heat of the hot wastewater produced after the work of the heat pump water heater is recovered as much as possible in a three-stage afterheat recovery way through the three-stage hot wastewater afterheat recovery device.
Description
Affiliated technical field
The utility model relates to the Teat pump boiler technical field, especially relates 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 carrys out 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 from water.The evaporimeter now used is mainly recirculation type evaporator and soaks two kinds, 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 needs to soak in pond or water pot and absorbs heat.All needing to supplement a large amount of water during this two kinds of evaporator operation provides heat to absorb to evaporimeter.If water shortage can cause Teat pump boiler heat production discharge reduction, when serious, more can cause Teat pump boiler to work.
In addition, waste water and the waste water after the toilet shower after the hair washing of present most of hairdressing place are all directly to emit, and all the waste heat in waste water are not reclaimed.Some water heaters with excess heat recovery device for shower waste water are arranged, but this retracting device be by running water after the interchanger in wastewater tank, absorb 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.。
The utility model content
Problem to be solved in the utility model is to provide a kind of thermal wastewater waste-heat recovery device of efficient Teat pump boiler.
Problem to be solved in the utility model, can realize by following technical scheme: a kind of three grades of thermal wastewater waste-heat recovery devices of Teat pump boiler, include to collect the main header tank of thermal wastewater, it is characterized in that: heat exchanger is installed in described main header tank from top to bottom successively, the first evaporimeter and the second evaporimeter, wherein the second evaporimeter is arranged on one and is contained in main header tank and in the secondary header tank of the below of the first evaporimeter, heat exchanger is serially connected on the water inlet pipe of Teat pump boiler, the first evaporimeter and the second evaporimeter serial connection, the output of the first evaporimeter is docked with the entrance of the compressor of Teat pump boiler, the input of the 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 arranged on the bottom, bathroom.
The beneficial effect that adopts the utility model to bring: three grades of thermal wastewater waste-heat recovery devices of the utility model can utilize the water of saving in advance in secondary header tank, are used for the thermal source of draw heat when starting working as Teat pump boiler.The spent hot water's who produces after Teat pump boiler work heat, reclaims spent hot water's heat by three grades of waste heat recoveries as much as possible through the utility model.Visible the utility model 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, carry out maintaining heat pump water heater required heat supplement of when normal operation, thereby avoid providing heat with a large amount of water.
The accompanying drawing explanation
The structural representation of three grades of thermal wastewater waste-heat recovery devices that Fig. 1 is the utility model Teat pump boiler.
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 to collect the main header tank 1 of thermal wastewater, concrete, and main header tank 1 is arranged on the bottom, bathroom.Heat exchanger 2, the first evaporimeter 3 and the second evaporimeter 4 are installed in described main header tank 1 from top to bottom successively, wherein the second evaporimeter 4 is arranged on one and is contained in main header tank 1 and in the secondary header tank 5 of the below of the first evaporimeter 3, heat exchanger 2 is serially connected on the water inlet pipe of Teat pump boiler, the first evaporimeter 3 and the second evaporimeter 4 serial connections, the output of the first evaporimeter 3 is docked with the entrance of the compressor of Teat pump boiler, and the input of the 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 to water (when Teat pump boiler is used for the first time), do initial heat source, Teat pump boiler is drawn the heat of the water in header tank 5, and the water in storage tank is carried out to heat pump to 55 ℃ or higher.While using hot water, 42 ℃ of hot water spray from gondola water faucet, and the spent hot water finally is pooled in main header tank 1, and at first the spent hot water carries out first order heating to the running water of the heat exchanger 2 of flowing through, water after 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 after heat exchanger 2, and water temperature is down to 25-30 ℃ of left and right, then and the refrigeration working mediums in the 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 after the first evaporimeter 3, water temperature is down to 15-20 ℃ of left and right, finally flow in secondary header tank 5 and carry out heat exchange with the 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 5-7 ℃ of left and right and drains from the bottom of main header tank 1 after three grades of waste heat recoveries.
