Description
Technical field
The utility model relates to water and heats technical field, particularly the waste water heat recovering equipment of a kind of bathing, industrial hot water etc.
Background technology
A lot of bathroom, enterprises and institutions, colleges and universities, hotel, hospital etc. all need hot water, particularly bathroom, warm water after being finished is all directly enter municipal sewage pipe network, because heating water for bathing needs to allow water bring up to about 45 DEG C usually, and the thermal energy consumption of water for bathing only about 10 DEG C in bathing process, bath wastewater temperature is about 35 DEG C, directly enters municipal sewage pipe network, a large amount of heat energy can be wasted like this, be unfavorable for energy-conserving and environment-protective.
Summary of the invention
For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of waste-heat recovery device that can effectively utilize shower waste water residual heat to improve cold water initial temperature.
Problem to be solved in the utility model, can be realized by following scheme: a kind of waste water heat recovering equipment, comprise waste water header tank, heat water tank, use hot water place, trench collecting pipe, metallic recuperator, waste water outflow pipe, wherein trench collecting pipe is positioned at and uses hot water place, metallic recuperator and waste water outflow pipe are positioned at waste water header tank, it is characterized in that: bottom waste water header tank, establish a catch pit, be provided with at least one relief sewer bottom catch pit, relief sewer upper end is positioned at waste water tank side.A metal tube heat exchanger is established in waste water header tank middle and upper part, and metal tube heat exchanger upper end is connected with running water, and outlet connects and heats water tank.Be provided with trench collecting pipe with in hot water place, trench collecting pipe establishes an outlet, and the port of export is connected with waste water header tank water inlet.
A preferred embodiment of the present utility model: establish a sewage pump in the middle of waste water outflow pipe.
Adopt the beneficial effect that the utility model brings: this device has function of recovering waste heat, first, before running water enters and heats water tank, the waste water be finished carries out preheating to running water, realizes waste heat recovery, after the full waste water tank of waste water collection, cold water sinks down into catch pit, utilizes the gravity of self to overflow, and whole device realizes without any power cycle, without operating cost, when waste water header tank is lower than drain, waste water outflow pipe adds a sewage pump, sewage is discharged.Reach preheating cold water, the object of energy-saving and emission-reduction.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of waste water heat recovering equipment of the utility model.
Fig. 2 is the structure chart that the waste water outflow pipe of a kind of waste water heat recovering equipment of the utility model adds sewage pump.
In figure 1, waste water header tank, 2, use hot water place, 3, heating equipment, 11, metallic recuperator, 12, waste water outflow pipe, 13, catch pit, 14, sewage pump.21, trench collecting pipe, 22, use hot water point.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, a kind of waste water heat recovering equipment, comprise waste water header tank 1, with water place 2 and heat water tank 3 for hot water preparing, catch pit 13 is provided with bottom described waste water header tank 1, catch pit 13 is at least lower than bottom waste water header tank 1 meter, waste water outflow pipe 12 is also provided with in described waste water header tank, the bottom of catch pit 13 is stretched in waste water outflow pipe 12 one end, the other end is positioned at top position, waste water header tank 1 side, a metal tube heat exchanger 11 is also established in described waste water header tank, metallic recuperator one termination running water water inlet, another termination water heating case 3, the metallic heat exchanging tube of running water in waste water header tank enters and heats water tank 3.
As shown in Figure 2, establish a sewage pump 14 in the middle of described waste water outflow pipe, sewage can be drained into more than waste water header tank plane.
Described with water place 2, inside establish trench collecting pipe 21 and with water spot 22, trench collecting pipe 21, lower than with water spot 22, can be bathroom with water place, can be also industrial heat water spot, and the hot water be finished enters waste water header tank after the collection of trench collecting pipe.
Described heats water tank 3, can be the equipment of any one heating water in electric heater, boiler, solar water heater etc.
Utility model works principle is as follows: after trench collecting pipe 21 is collected, enter waste water header tank 1 with the waste water of hot water point 22 discharge, the layering in water tank of waste water in waste water header tank 1, cold water is in sinking, hot water liter, by waste water outflow pipe 12, the cold water of bottom is discharged after waste water header tank water is full, heat in waste water header tank, before entering and heating water tank, is cemented out by metallic recuperator, carries out preheating to running water by running water.Improve the basic water temperature of running water.
