Abstract
A multistage wastewater heat energy utilizing device comprises a wastewater accommodating tank body, a wastewater inlet is arranged above the tank body, and a wastewater outlet is arranged under the tank body. Cold water pipes are arranged in the wastewater accommodating tank body and coiled into horizontally spiral coil pipes, a water inlet of each cold water pipe is arranged under the tank body, and a water outlet of each cold water pipe is arranged above the tank body. Preferably, the cold water pipes are arranged in the wastewater accommodating tank body, a plurality of spiral coil pipes are arranged from top to bottom, and water flowing gaps are reserved on the coil pipes. The multistage wastewater heat energy utilizing device has the advantages that hot wastewater is in the device and heats cold water which is in the spiral coil pipes and enters a water heater, and heat in the wastewater is transferred to the cold water as far as possible so as to improve cold water temperature and reduce energy consumption of the water heater in water boiling process.
Description
Technical field
The utility model relates to a kind of heat-exchanger rig, especially a kind of device that utilizes the heat energy heating cold water in the waste water.
Background technology
Water heater is a kind of device that heats cold water to uniform temperature, improves cold water temperature energy savings, the raising efficiency of heating surface significantly.On the other hand, in daily life, like hair washing, in this type water activity of having a bath, wastewater temperature is higher, and this water generally all is to use various water heaters heating to form, and two kinds connect and can seek a kind of method for saving energy undoubtedly.
The utility model content
The purpose of the utility model is a kind of device that utilizes the heat of sanitary wastewater of invention, is used for the cold water that gets into water heater is preheated, and improves energy utilization rate.
The utility model contains a waste water and holds casing, and the casing top is provided with the waste water import, and the below is provided with wastewater outlet; Waste water holds in the casing, is provided with the cold water water pipe, and described cold water water pipe dish becomes flat spin shape coil pipe, and the water inlet of cold water water pipe is located at the below, and the delivery port of cold water water pipe is above casing.
Preferably: the cold water water pipe is provided with a plurality of helical form coil pipes from top to bottom in waste water holds casing, the flowing water space is arranged on the coil pipe.
Preferred 1 of flowing water space: the flowing water space on the coil pipe is arranged in the outermost of coil pipe.
Preferred 2 of flowing water space: the flowing water space on the coil pipe is arranged in the center of coil pipe.
The beneficial effect of the utility model is that the waste water of heat is in this device; Heating is through the cold water that will get into water heater in the helical form coil pipe; Transfer in the cold water the heat in the waste water is as much as possible; Improve the cold water water temperature, reduce the energy consumption that water heater is heated up water, can show effects such as economize on electricity, water heater water outlet in winter water temperature height.
Description of drawings
Fig. 1, the preferred structure figure of the utility model.
Fig. 2, a kind of structure chart of the helical form coil pipe 6 of the utility model.
Fig. 3, the another kind of structure chart of the helical form coil pipe 6 of the utility model.
The specific embodiment
Like Fig. 1, an embodiment of the utility model.Waste water storage case 1 is cylindrical, and the top is provided with water intake 2, and wastewater effluent mouth 3 is arranged on the below, and cold water inlet 5 is arranged on the below of waste water storage case 1, and cold water delivery port 4 is arranged on the top of waste water storage case 1.
Cold water pipes is shape coil pipe 6 distributions in the shape of a spiral in waste water storage case 1 inside, and in the present embodiment, helical form coil pipe 6 is provided with multistage from bottom to top, and every grade all is the helical form coil pipe of a level.And the helical form coil pipe is provided with flowing water space 7, and the arrangement in described flowing water space has two kinds: a kind of like Fig. 1; Be arranged on the center of coil pipe; Another kind is like Fig. 2, is arranged in the outermost all around of helical form coil pipe, and the helical form coil pipe with two kinds of flowing water spaces is provided with at interval.In the present embodiment, in three grades of helical form coil pipes 6, the flowing water space 7 of middle coil pipe is arranged on the center, up and down around being arranged on of two-stage.
In the time of work, waste water flows into from the water intake 2 of top, flows to uppermost one-level helical form coil pipe 6; Spread all over then on the coil pipe, carry out heat exchange with cold water in the coil pipe, then through around flowing water space 7 flow to second level coil pipe; Water (flow) direction on the helical form coil pipe of the second level is from flowing to middle flowing water space all around; Flow to third level coil pipe at last again,, flow out from wastewater effluent mouth 3 from the flowing water space of intermediate flow to four limits.Accomplish 3 heat exchanges with the coil pipe inner cold water altogether therebetween.Because the waste water water (flow) direction is opposite with the cold water water (flow) direction, so when can guarantee each heat exchange, both temperature difference are maximum, the effect of raising heat exchange.
