Description
Technical field
The present invention relates to a kind of waste recovery method and device, particularly a kind of heat extraction method of domestic waste hot water and device thereof.
Background technology
Raising along with living standards of the people, the use amount of daily life hot water improves year by year, most domestic hot-water is just directly discharged after using, and ASSOCIATE STATISTICS shows that the spent hot water's that lives average temperature is about 32 ℃, it is good low-grade heat source, China is populous nation in addition, and life spent hot water's total emission volumn is very big, with this direct discharging of waste water that has a large amount of heat energy, not only waste energy, and increased environment pollution.
Summary of the invention
The objective of the invention is provides a kind of spent hot water of family heat that can extract for the deficiency that solves above-mentioned technology, and is used for pre-warmed heat extraction method of domestic waste hot water of living water use and device thereof.
In order to achieve the above object, a kind of heat extraction method of domestic waste hot water that the present invention is designed, it comprises heats water at low temperature by used heat extraction element extraction heat the spent hot water, the spent hot water who it is characterized in that extracting heat obtains in the floor drain by waste discharge, spent hot water's adapter cavity is set in floor drain, the spent hot water extracts path and waste water drainage channel, by negative pressure of vacuum the spent hot water in the floor drain being extracted path through the spent hot water sends into used heat in airtight spent hot water's storage box in the used heat extraction element and extracts heat exchanger and extract heat, by the heat release heat exchanger heat release in the used heat extraction element, the water at low temperature that will have in the water tank of heat effect preheats, extract waste water behind the heat and lead up to waste water drainage channel discharging in the floor drain, another road connects waste water recycling water tank.
According to described heat extraction method of domestic waste hot water, a kind of life spent hot water heat extraction device of its realization, it extracts floor drain by the spent hot water, strainer, connecting line, electromagnetic valve, control valve, airtight spent hot water's storage box connects and composes the life spent hot water successively and extracts closed circuit, spent hot water's adapter cavity is set in floor drain, the spent hot water extracts path interface and waste water drainage channel interface, spent hot water in the floor drain extracts the path interface and is communicated with the water inlet of airtight spent hot water's storage box, waste water drainage channel interface in the floor drain is communicated with the delivery port of airtight spent hot water's storage box, minipump is installed in the top of airtight spent hot water's storage box, its air entry links to each other with the top of airtight spent hot water's storage box, used heat extracts heat exchanger and is installed in airtight spent hot water's storage box inside, and the delivery port of airtight spent hot water's storage box is communicated with the discharge of wastewater interface of floor drain.Pressure sensor is installed on airtight spent hot water's storage box, and pressure sensor is connected by control line with minipump.In the implementation process, used heat extracts heat exchanger, compressor, heat release heat exchanger, throttle part and connects the system that copper pipe is formed the transfer of heat function jointly, and the heat release heat exchanger places the water tank that has heat effect.The system of transfer of heat function also can be extracted heat exchanger, compressor, heat release heat exchanger, throttle part, water pump and be connected copper pipe and form jointly by used heat, and the heat release heat exchanger is connected with the water tank that has heat effect by water pump.
Life the spent hot water can be stored when flowing through floor drain, is easy to be recovered and has a preliminary filtering function.The strainer of flowing through is carried out smart filter, and the waste water that assurance is flow through behind the strainer does not have solid matter.Two interfaces of floor drain, one be used to obtain the spent hot water, another is used to extract the discharge of wastewater behind the heat.Electromagnetic valve has two effects, and the one, after airtight spent hot water's storage box held full spent hot water, closed electromagnetic valve guaranteed that the spent hot water does not reflux, and is convenient to heat utilization; Another effect is behind closed electromagnetic valve, forms closed system, is convenient to vacuum pump and forms negative pressure.Pressure sensor is connected by control line with minipump, and control vacuum pump unlatching and stop.When the vacuum pump work, can make waste water extraction passage and water storage box internal pressure be lower than atmospheric pressure, the spent hot water will enter airtight spent hot water's storage box by the above-mentioned passage in externally atmospheric effect lower edge, pressure sensor can obtain the case internal pressure, situation of change by pressure, make the work of controller control vacuum pump, make the interior pressure stability of case in certain scope.When water level rises to certain altitude, controller can make closed electromagnetic valve, closes vacuum pump simultaneously.It is to guarantee that water does not enter into the admission pipe of vacuum pump that fluviograph also has a critical function, the work of protection vacuum pump normal reliable.The effect of transparent pipe is can observe the regimen condition in use, the effect of control valve is a relative equilibrium between the water yield of the flow of waste water when making shower by its aperture of manual adjustments when first use the and extraction, makes to keep that in use stable water inlet can be arranged.
According to the resulting a kind of life spent hot water heat extraction device of heat extraction method of domestic waste hot water provided by the present invention, easy to operate, directly perceived, stable, can make full use of the heat resource among the spent hot water, life used heat in the family is reclaimed, and discharge behind the extraction heat, it is energy conservation not only, for family saves a large amount of energy costs, and minimizing has good economic and social benefit to the heat pollution of environment.
