Description

A kind of bath wastewater heat reclamation device
Technical field
The utility model is the waste water retracting device, relates in particular to a kind of bath wastewater heat reclamation device, can be used for being equipped with in the building of concentrating bath system, as buildings such as residential houses, bath center, hairdressing places.
Background technology
Bath hot water in numerous buildings is directly drained from sewer, has not only wasted a large amount of available heat energy, also surrounding environment has been caused thermal pollution; Contain a large amount of hairs, sewage etc. in the bath wastewater simultaneously, directly drain also and can pollute environment.
Traditional bath wastewater heat reclamation device is at building interior or the Waste Water Centralized pond is set on every side, bath wastewater collected carry out heat exchange with running water and realize recuperation of heat.Running water raises by temperature behind the heat of heat exchange coil absorption bath wastewater in the Waste Water Centralized pond, delivers to the heat resource equipment place through water circulating pump.
The operation practice is found: long-time running, and the sewage in the Waste Water Centralized pond is smelly to bring secondary pollution to environment; The heat exchange coil fouling is difficult to clean; The resistance that running water flows in heat exchange coil is big, and the effective discharge that flows through in the heat exchange coil of unit interval reduces, and the heat exchange efficiency of heat reclamation device reduces.And big in site coverage, do not allow to be provided with the place in Waste Water Centralized pond, then can not use the traditional Waste Water Centralized pond and the system form of heat exchange coil.
Summary of the invention
Technological deficiency at above-mentioned traditional Waste Water Centralized pond and heat exchange coil heat recovery system, the purpose of this utility model aims to provide the bath wastewater heat reclamation device that does not need to be provided with the Waste Water Centralized pond, solved bath wastewater recuperation of heat problem on the one hand, secondary pollution and the lower problem of heat exchange efficiency that the heat recovery system form with Waste Water Centralized pond and heat exchange coil causes have been solved on the one hand in addition, water system need not additionally be provided with water circulating pump simultaneously, realize the low-power consumption heat exchange, saved electric energy.Because the core component of this device adopts double-tube heat exchanger, the heat exchange efficiency of bath wastewater and running water is greatly enhanced, and attemperater has also reduced the heat loss of bath wastewater simultaneously.So just can accomplish cascade utilization, improve utilization efficiency of energy the energy.
In order to realize the effect of above-mentioned utility model, the technical scheme that the utility model is taked is:
A kind of bath wastewater heat reclamation device, comprise filter, attemperater, bracket base, double-tube heat exchanger, block valve, dosing mouth and blowoff valve, wherein, bracket base and attemperater are welded as a whole, wherein bracket base can adopt cast iron, attemperater adopts stainless steel material, double-tube heat exchanger is installed on the attemperater, pass through bolting, wherein the inner sleeve of double-tube heat exchanger adopts the copper tube that has ripple, outer tube adopts the PE pipe, and double-tube heat exchanger is provided with water inlet pipe and outlet pipe.
Be provided with double-tube heat exchanger in the attemperater, the inner sleeve of double-tube heat exchanger adopts the ripple copper tube, and outer tube adopts the PE pipe.
Water inlet pipe is provided with openable block valve and dosing mouth, and the outlet pipe place is provided with block valve and blowoff valve simultaneously.
Attemperater is provided with heat-insulation layer, and the thickness of heat-insulation layer is determined according to the size of water tank.
The good effect of the technical solution of the utility model is:
1, bath wastewater and running water carry out countercurrent flow by the ripple copper tube in sleeve pipe, and heat exchange efficiency improves, and is more energy-conservation.
2, because this heat reclamation device volume is little, it is easy to install, can use in the big zone of site coverage, have very strong flexibility.
3, after hair, mud are filtered, can not produce secondary pollution to environment because the pond is smelly.
4, only depend on the pressure of running water to circulate, need not to be provided with water pump, need not additionally to increase power consumption.
5, this device has been set up the dosing cleaning function, is convenient to clean, and helps to improve heat exchange efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As seen from Figure 1, this bath wastewater heat reclamation device, form by bracket base 1, attemperater 3, double-tube heat exchanger 4, filter 6, blowoff valve 7, block valve 2, block valve 5, block valve 8, block valve 9 and dosing mouth 10, bracket base 1 is welded as a whole with attemperater 3, wherein bracket base 1 adopts iron casting, and attemperater 3 adopts stainless steel and other metal materials.In order to reduce the heat leakage of bath wastewater and surrounding environment, on attemperater 3, add one deck heat-insulation layer.Double-tube heat exchanger 4 is installed in the attemperater 3, and by bolting, wherein the inner sleeve of double-tube heat exchanger 4 adopts the copper tube that has ripple, and outer tube adopts the PE pipe, and double-tube heat exchanger 4 is provided with water inlet pipe 11 and outlet pipe 12.
When system moves, open block valve 2, block valve 8, block valve 9, close block valve 5 and blowoff valve 7, bath wastewater at first flow into filter 6 in the heat reclamation device through the screen pack between bathing, in double-tube heat exchanger 4 with from the running water of opposite side, constantly carry out heat exchange, finally drain into sewer, running water then is heated, and temperature is sent to heat resource equipment after raising.Regularly clean the outer tube of this heat reclamation device heat exchanger 4 and the dirt between the inner sleeve, when cleaning dirt, at first block valve 8 and block valve 9 are closed, open block valve 5, and will clean medicine from dosing mouth 10 importings, open blowoff valve 7 behind the certain hour to be cleaned, finish the cleaning of heat exchanging device, can guarantee the long-term use of heat reclamation device like this.
Generally more than 30 ℃, the design of heat exchanger designs according to winter condition the temperature of bath wastewater.Mean temperature with Changsha running water in the coldest month January of winter is an example for 5 ℃, suppose that the heat of running water absorption bath wastewater rises to 20 ℃, and the temperature of bath wastewater outlet is 24 ℃.
In order not make the heat exchanger 4 in the heat reclamation device attemperater 3 excessive, adopt the interior copper pipe that has ripple to increase heat exchange area, improve effective heat exchange amount of heat exchanger 4.
This heat reclamation device in use, the bath wastewater that contains booties such as hair, mud through the screen pack in the shower cabinet after, the space and the running water that enter heat exchanger outer tube and inner sleeve carry out heat exchange.Because inner sleeve is the copper tube that has ripple, has increased effective heat exchange area between the two.Behind counter-flow heat exchange, running water can fully absorb the heat of bath wastewater, and is sent to heat resource equipment by hydraulic pressure from the beginning, and bath wastewater then drains into sewer.
