Technical field
The present invention relates to a kind of heat reclamation device, especially relate to a kind of bath wastewater two levels of thermal retracting device.
Background technology
Along with improving constantly of people's quality of the life, domestic hot-water's energy consumption constantly increases at the proportion of architectural energy consumption, in conventional bath system, that the higher bath wastewater of temperature enters sewerage after directly will using, so that the contained heat that is higher than environment temperature is wasted in the sewage, more serious for this loss of large-scale centralized formula bath system.Actual bath energy consumes the temperature difference only about 5 ℃, the bathing that contains a large amount of heat energy is landed water-white and has been entered in vain sewer, cause the consumption of bath water energy, the bathing Btu utilization only accounts for and adds 16.7% of the required heat of hot tap-water, remaining heat of 83.3% then is discharged, and wherein comprises the available energy of the temperature that is higher than environment.And the bath wastewater temperature stabilization, flow is suitable, and the potentiality of recuperation of heat are larger.Therefore, utilizing heat pump to reclaim the heat of bath wastewater, reduce part hot water preparation power consumption, is a kind of energy utilization mode of energy-conserving and environment-protective.Application number is the utility model patent of " 200620024573.9 ", a kind of air source hot pump water heater with waste heat recovery plant is disclosed, it comprises by air heat-exchange evaporimeter, the compressor that links to each other with the input of air heat-exchange evaporimeter, output two ends respectively, the working medium circulation loop that condenser forms, condenser is the thermal source of heat-exchanging water tank, heat-exchanging water tank is communicated with respectively hot water outlet and cooling water inlet, also comprise the wastewater heat exchange evaporimeter of being located in the waste water collector, its input, output are connected to respectively input, the output of air heat-exchange evaporimeter.Although this utility model makes the heat energy in the bath wastewater obtain the part utilization, heat recovery rate is lower, and heat energy of bathing waste water does not take full advantage of.
Summary of the invention
The objective of the invention is: provide a kind of heat recovery rate high, energy-efficient bath wastewater two levels of thermal retracting device.
Technical scheme of the present invention is: comprise compressor, condenser, heat exchanger, the input port I of heat exchanger connects the water leg of dress bath wastewater, the delivery outlet I of heat exchanger connects the input port IV of evaporimeter, the delivery outlet IV access discharge outlet of evaporimeter, form the one-level heat exchanging pipe between the input port I of heat exchanger and the delivery outlet I, another input port II of heat exchanger connects running water pipe, the delivery outlet II connects heat-collecting box, forms one-level heat-obtaining pipeline between the input port II of heat exchanger and the delivery outlet II; Condenser is housed in the heat-collecting box, another input port V of evaporimeter connects the delivery outlet V of condenser by throttling arrangement, the delivery outlet VI of evaporimeter connects compressor inlet, compressor outlet connects the input port VI of condenser, form the secondary heat exchange pipeline between the input port IV of evaporimeter and the delivery outlet IV, form secondary heat-obtaining pipeline between evaporimeter, compressor, condenser, the throttling arrangement.
Described heat exchanger is arranged in the water leg.
Described heat-collecting box is connected with control system.
Described compressor, evaporimeter, heat-collecting box are arranged in the housing.
The invention has the beneficial effects as follows: because the input port I of heat exchanger connects the water leg of dress bath wastewater, the delivery outlet I of heat exchanger connects the input port IV of evaporimeter, form the one-level heat exchanging pipe between the input port I of heat exchanger and the delivery outlet I, another input port II of heat exchanger connects running water pipe, the delivery outlet II connects heat-collecting box, form one-level heat-obtaining pipeline between the input port II of heat exchanger and the delivery outlet II, bath water flows into water leg, behind the heat in the heat exchanger absorption water leg, tap water heating is flowed into heat-collecting box, finish the one-level heat-obtaining.Owing to forming secondary heat-obtaining pipeline between evaporimeter, compressor, condenser, the throttling arrangement, through extracting the waste water of heat by the heat in the evaporimeter double absorption waste water for the first time, the compressed machine of refrigerant is collapsed into high temperature and high pressure gas, enter the condenser in the heat-collecting box, the condensation liquefaction heat release becomes liquid, simultaneously with the heating of the water in the heat-collecting box, thereby reaches the purpose of producing bath water, finish the secondary heat-obtaining, drain through the bath wastewater inflow sewer of second extraction heat.Simultaneously, heat-collecting box is connected with control system, and when the temperature in the heat-collecting box reached the bathing temperature, compressor quit work, by one-level heat-obtaining device continuous heat supply; When the temperature in the heat-collecting box does not reach the bathing temperature, by one-level, the simultaneously heat supply of secondary heat-obtaining device, move in circles with this.Heat recovery rate of the present invention is high, and is energy-efficient, safe and reliable, can be used for the places such as family, unit, bath center.
