Abstract

The utility model provides a bathroom sewage waste heat recovery device which solves the problem that in the prior art, a dynamical transport device is required to be added during a sewage cyclic utilization process. Recovery of waste heat can be achieved through a heat exchange between bath sewage and running water. During an installation process, automatic inflow of the bath sewage into a heat exchanger is achieved through the fact that the heat exchanger is installed on a building surface or below the ground. Meanwhile, a filter is installed on the upstream of the heat exchanger. The installation height of the filter is higher than that of the heat exchanger. Therefore, the fact that sewage flowing out of the filter can automatically flow into the heat exchanger is achieved. According to the bathroom sewage waste heat recovery device, during a bath sewage transporting process, the dynamical transport device is not required to be added, and sewage can be treated, so that cost of introduction of a pump or a heat pump is saved during the installation process. Meanwhile, energy required during operation of the pump or the heat pump is saved during a utilization process of the bathroom sewage waste heat recovery device.

Description

A kind of bathroom sewage waste heat recovery device
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, there are many energy resources that are not used just so to waste in our life, 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 40 ℃ of left and right from the bath water tap, the bathing process has generally only consumed the temperature difference of 10 ℃, bath wastewater is also 30 ℃ of left and right, 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 on " energy-conservation " magazine in 2006 as Chai Xiaowei, systematically discussed the design of bathroom waste heat recovery, a large amount of waste heats in bath sewage have been reclaimed, and sewage is 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 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 arranged on 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 the interior foreign material of scavenge filter 2.
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 arranged on it in wall.Should note reserving the space that is not less than filter 2 filtering net width and length on 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 above-mentioned bathroom sewage waste heat recovery device as of the present invention.
As another improvement of the present invention, can get back to further to heat in heater or mix hot water to preference temperature re-using from the heated running water of heat exchanger 1 port of export outflow.
As another improvement of the present invention, heat exchanger 1 is selected horizontal heat exchanger or horizontal installation.
Beneficial effect
The scheme that discloses in the present invention has been completed research and development and proof procedure, obtains energy-saving effect preferably, and its beneficial effect is enumerated as follows:
1, saving equipment and Energy input.Need not to add power conveying device to process sewage in the bath sewage course of conveying due to the present invention, so save the equipment cost of introducing pump or heat pump in installation process, and save simultaneously pump or the necessary energy of operation of heat pump in the device use procedure.
2, energy savings.Reclaim the bathroom waste water of 30 ℃, carry out heat exchange with the cold water of 10 ℃ of left and right, the cold water of 10 ℃ can be heated to the warm water of 25 ℃, and this moment, boiler or electric furnace only needed the warm water with 25 ℃ to be heated to 40 ℃, but not the cool water heating to 40 of 10 ℃ ℃, fuel and electric energy have been saved.
3, reduce pollution.Generally, 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 carry out holding back of solid waste before the waste water heat exchange, 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.
Description of drawings
Bathroom sewage waste heat recovery device described in Fig. 1 embodiment 1,1-heat exchanger in figure; The 2-filter; 3-flooring or ground; The 4-bath sewage; The 5-sewage conduct; 6-running water trunk line; Running water after 7-is heated; 8-does not add hot tap-water; The 9-house.
The specific embodiment
Further illustrate the present invention below in conjunction with drawings and Examples, wherein the part preparation condition is only the explanation as typical case, is not to be limitation of the invention.
Embodiment 1Bathroom sewage waste heat recovery device as shown in fig. 1 comprises heat exchanger 1 and filter 2, is installed in flooring or ground below 3, and filter 2 setting height(from bottom)s are higher than heat exchanger 1, so that the automatic inflow heat exchanger 1 of sewage that is flowed out by filter 2; During operation, bath sewage 4 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 5 and flows away, and heated running water 7 flows out for life from heat exchanger 1 port of export.
