Abstract
The invention provides a bathroom sewage waste heat recovery device aiming at solving the problem that power delivery equipment is required to be added in a sewage recycling process in the prior art. The bathroom sewage waste heat recovery device is used for recovering waste heat through heat exchange between bathing sewage and running water; and during an installation process of the bathroom sewage waste heat recovery device, a heat exchanger is arranged on a floor or under the ground to achieve the effect that the bathing sewage can automatically flow into the heat exchanger, and a filter is arranged at the upstream of the heat exchanger and higher than the heat exchanger, therefore, the sewage flowing out of the filter automatically flows into the heat exchanger. According to the device, during a bathing sewage delivering process, the sewage can be processed without adding the power delivery equipment, so that the equipment cost for introducing a pump or a heat pump in the mounting process is saved, and meanwhile, energy required for operation of the pump or the heat pump in the using process of the device is also saved.
Description
Technical field
The invention belongs to plumbing technology, technical field of heat exchange, relate in particular to a kind of bathroom sewage waste heat recovery device.
Background technology
Closing on of energy crisis forces the eager development of new energy of people, and a effective way that at present can alleviating energy crisis is exactly to improve the utilization ratio of the energy.Therefore develop the UTILIZATION OF VESIDUAL HEAT IN technology, research and development novel multiple residual heat using device will have vast development prospect.Many facts have proved, in our life, there are many energy resources that are not used just so to waste, such as high-temperature boiler flue gas, high temperature automotive tail gas, have popular bathroom waste water of moderate temperature etc., especially the UTILIZATION OF VESIDUAL HEAT IN of bath wastewater, usually out water is about 40 ℃ from the bath water tap, the bathing process has generally only consumed 10 ℃ the temperature difference, bath wastewater is also about 30 ℃, this part heat has just wasted, and the heating water for bathing makes it to raise 30 ℃ and also need consume energy resources.So, the utilization rate of the energy is very low, has 2/3 energy to be wasted.
Research about the afterheat of hot water recovery aspect of middle low temperature appears in the newspapers already, delivered the article of " Preliminary design of bathroom waste heat recovery and energy conserving system " by name at " energy-conservation " magazine in 2006 such as Chai Xiaowei, systematically discussed the design of bathroom waste heat recovery, a large amount of waste heats in the bath sewage have been reclaimed, and sewage processed, improved the efficiency of system, heat and water all are fully utilized.Disclosed patent has " a kind of waste heat recovery type hot-water boiler device in bathroom " (Granted publication CN101520208 B) and " bath wastewater exhaust heat recovery apparatus " (Granted publication CN202284873U) simultaneously, and the part that all comes with some shortcomings in these prior aries, the most obvious defective is to need to increase the power conveying equipment in the process of effluent cycle utilization, the equipment and the energy loss that increase thus.
?
Summary of the invention
The technical problem that solves:Need to increase problem and the demand of power conveying equipment in the process for above-mentioned effluent cycle utilization, the invention provides an effective solution.
Technical scheme:A kind of bathroom sewage waste heat recovery device comprises heat exchanger 1 and filter 2; Bath sewage is by floor drain inflow filter 2, inflow heat exchanger 1 hot fluid entrance point after filtering, running water is conveyed into heat exchanger 1 cold fluid entrance point simultaneously, the cold fluid and hot fluid counter-current flow is carried out heat exchange, the sewage of discharging enters sewage conduct and flows away, heated running water from heat exchanger 1 port of export flow out for; Heat exchanger 1 and attached connecting pipe thereof are installed in flooring/below ground, filter 2 be installed in flooring/ground above or below, setting height(from bottom) is higher than heat exchanger 1, so that the automatic inflow heat exchanger 1 of sewage that is flowed out by filter 2.
When filter 2 was installed at flooring/below ground, its lid was exposed to the earth's surface, so that scavenge filter 2 interior foreign material.
As a further improvement on the present invention, above-mentioned heat exchanger is plate type heat exchanger.
Further improve as of the present invention, if the ground face thickness is not enough to install lower heat exchanger 1 and/or filter 2, can be installed in it in wall.Should note reserving the space that is not less than filter 2 filtering net width and length at wall for the installation of filter 2, make screen pack can conveniently take out the cleaning foreign material.
Further improve filter 2 and heat exchanger 1 being made of one structure in the above-mentioned bathroom sewage waste heat recovery device as of the present invention.
As of the present invention another improve, the heated running water that flows out from heat exchanger 1 port of export can be got back to further to heat in the heater or mix hot water to preference temperature and re-using.
As another improvement of the present invention, heat exchanger 1 is selected horizontal heat exchanger or horizontal installation.
Beneficial effect
The scheme that discloses among the present invention has been finished research and development and proof procedure, obtains preferably energy-saving effect, and its beneficial effect is enumerated as follows:
1, saving equipment and Energy input.Because the present invention need not to add power conveying device and can process sewage in the bath sewage course of conveying, so save the equipment cost of in installation process, introducing pump or heat pump, and save simultaneously pump or the necessary energy of operation of heat pump in the device use procedure.
2, energy savings.Reclaim 30 ℃ bathroom waste water, carry out heat exchange with the cold water about 10 ℃, 10 ℃ cold water can be heated to 25 ℃ warm water, and this moment, boiler or electric furnace only needed the warm water with 25 ℃ to be heated to 40 ℃, but not 10 ℃ cool water heating to 40 ℃, fuel and electric energy have been saved.
3, reduce pollution.Generally speaking, the bath wastewater in bathroom directly drains into sewer, and the remaining solid waste of some bathings easily causes environmental pollution.Use native system, can before the waste water heat exchange, carry out holding back of solid waste, waste water is carried out decontamination process, in order to avoid cause obstruction and the corrosion of heat exchanger, can be used for flushing the toilet or field irrigation finally by the waste water of crossing heat exchange.
4, using water wisely.Waste water can fully utilize, and compares than original direct discharging, has improved the utilization rate of water resource, has saved water resource.
