Description

A kind of bathroom sewage heat energy retracting device
Technical field:
The utility model relates to a kind of bathroom sewage heat energy retracting device.
Background technology:
Existing bathroom water for bathing is after using, and sewage generally directly drains into sewer, and the heat energy in the sewage has also slatterned thereupon.This causes the waste of the energy on the one hand, has also increased bathroom operating cost on the other hand.If the energy recovery in the sewage is got off, water purification is preheated, will greatly reduce bathroom the first transaction of a day's business cost, cut down the consumption of energy energy savings.The hot sewage temperature that discharge in general bathroom is about 40 ℃, in the winter time, the running water temperature is below 10 ℃, if the temperature that we utilize hot sewage by heat exchanger with about running water temperature increase to 32 ℃, a little is heated to the running water that is preheated again, can directly use for the bathroom, this will reduce energy resource consumption greatly, and great promotional value is in industry arranged.
Summary of the invention:
The utility model provides a kind of bathroom sewage heat energy retracting device, realizes energy recovery, directly discharge thereby solved existing bathroom water for bathing, and the energy waste that causes, and reduced the operating cost in bathroom.
In order to achieve the above object, technical solution of the present utility model is: it partly is made up of hot sewage discharge groove, filter, sewage pump, magnetic valve reversal valve, liquid level gauge, heat exchanger, electric cabinet and pipeline etc., and hot sewage discharge groove, filter, sewage pump, heat exchanger connect successively by pipeline; Cold water to be exchanged, solenoid directional control valve, heat exchanger also connect successively by pipeline.
The inner walls of filter evenly is provided with the screen pack slot, and thick, half smart, smart screen pack is inserted in the screen pack slot respectively in order.
Electric cabinet links to each other with solenoid directional control valve, liquid level gauge and sewage pump respectively.
The utility model has been realized the energy recovery of bathroom sewage and control automatically thereof.Avoid the waste of the energy on the one hand, also reduced bathroom operating cost on the other hand.
Description of drawings:
Below in conjunction with drawings and embodiments the utility model is elaborated.

Fig. 2 filtration device structure profile
Fig. 3 filter vertical view
Among the figure 1, hot sewage discharge groove 2,5, connecting pipe 3, liquid level gauge 4, filter 6, sewage pump 7, stop valve 8, heat exchanger heat import 9, the cold outlet 10 of heat exchanger, discharge of wastewater mouth 11, heat exchanger heat outlet 12, the cold import 13 of heat exchanger, solenoid directional control valve 14, heat exchanger 15, electric cabinet 16, filter cover 17, filter housings 18, handgrip 19, filter head housings bracing frame 20, cloth bag 21, coarse filtration net 22, half smart screen pack 23, smart screen pack 24, sewage pump inlet channel 25, screen pack slot 26, the pending hot sewage inlet of filter
The specific embodiment:
In Fig. 1,2, hot sewage discharge groove (1) passes through obliquely, and pipeline links to each other with filter (4), pipe outlet is connected by cloth bag (20) with filter housings (17) obliquely, the sewage pump inlet channel (24) of filter (4) lower end links to each other with sewage pump (6), sewage pump (6) outlet links to each other by pipeline with stop valve (7) one ends, and stop valve (7) other end is connected with heat exchanger heat import (8) by pipeline.As can be seen from the figure, the pending hot sewage of hot sewage discharge groove (1) lining savings flows to filter housings (17) lining of filter (4) by water-head, sewage enters three road screen packs in proper order, and the impurity in the hot sewage stayed filter housings (17) bottom, the water that flows to filter housings (17) outside hot sewage for having filtered, sewage pump (6) is extracted into heat exchanger heat import (8) with it, and enter heat exchanger (14), this flow process has guaranteed that the hot sewage that enters in heat exchanger (14) pipeline has higher cleannes, therefore, the hot sewage that filters through multiple tracks can not cause the obstruction of heat exchanger (14) interior conduit.By heat exchange hot sewage enter discharge of wastewater mouth (10) from the cold outlet of heat exchanger (9), thereby realized the exchange heat of hot sewage.
In Fig. 1, cold water to be exchanged links to each other with solenoid directional control valve (13) one ends by pipeline, and its other end is connected with the cold import of heat exchanger (12).Cold water to be exchanged is by the pressure in the pipeline, water is delivered to solenoid directional control valve (13), the electromagnet of solenoid directional control valve (13) gets, from then on water can pass through, and enter the cold import of heat exchanger (12) and carry out heat exchange, cold water temperature after the heat exchange is raised, and delivers to water tank to be heated by the heat outlet (11) of heat exchanger by pipeline, thereby has realized the energy recovery of sewage.Use through reality, 0~10 ℃ of environment temperature, 10 ℃ of cold water temperatures, 36~40 ℃ of hot water temperatures, when hot sewage and quality such as cold water to be exchanged exchanged, cold water temperature can stably be promoted to about 32-35 ℃.
In Fig. 2,3, filter housings (17) inwall evenly is provided with screen pack slot (25), screen pack slot (25) is welded on housing (17) inwall of filter, and coarse filtration net (21), half smart screen pack (22), smart screen pack (23) are inserted in respectively in the screen pack slot (25) in order; Coarse filtration net (21) front end at filter housings (17) has the pending hot sewage inlet of filter (26), and it is connected by cloth bag (20) with pipe outlet obliquely.During filter (4) work, hot sewage enters coarse filtration net (21) from cloth bag (20) junction, the most of hairline of elimination, when more than half smart screen packs (22), broken hairline of elimination and part greasy filth, pass through smart screen pack (23) at last, the molecule that elimination is remaining, hot like this sewage filters basic elimination greasy filth particle and hairline through three roads, hot effluent stream after the filtration is to the outside of filter housing (17), and the filtered water and the inboard hot sewage in filter housings (17) outside separate by cloth bag (20) and smart screen pack (23).Screen pack can arbitrarily pull and push on filter, makes things convenient for the cleaning and filtering net.Open filter cover (16), hand is grabbed filter housings handgrip (18) can take out cleaning with filter housings.
At Fig. 1, in 2, electric cabinet (15) is connected by lead with solenoid directional control valve (13), liquid level gauge (3) and sewage pump (6) respectively.Liquid level gauge (3) is screwed on filter head housings bracing frame (19).Liquid level gauge (3) lower end is placed in the hot sewage that has filtered, when filter (4) middle water level is higher than liquid level gauge (3) desired location, the liquid level gauge sender, and by the electrical control in the electric cabinet (15), the electromagnet of solenoid directional control valve (13) is got, allow sewage pump (6) energising work, cold water at this moment to be exchanged enters heat exchanger (14) from solenoid directional control valve (13) and carries out heat exchange, while sewage pump (6) also is drawn into hot sewage heat exchanger (14) and carries out heat exchange, cold water temperature after the heat exchange is raised, and deliver to water tank to be heated by pipeline, thereby realized the energy recovery of sewage by the heat of heat exchanger outlet (11).When filter (4) middle water level was lower than liquid level gauge (3) desired location, the liquid level gauge sender by the electrical control in the electric cabinet, was closed solenoid directional control valve and sewage pump equally.Thereby realized the automatic control of energy recovery.
The real sewage heat energy that is mainly used in the bathroom of the utility model reclaims, and belongs to energy saving and environment friendly product, and its input cost is low, and return rate is very high, has bigger promotional value.
