The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the wastewater heat recovery device of the utility model embodiment comprises treatment device for water 1, fountain heat-exchanger rig 2 and condensation unit 3.Wherein, fountain heat-exchanger rig 2 is a box typed structure, and two-layer about being separated into, and the upper strata is a spraying box, and lower floor is a waste water tank, and the casing outside is provided with circulating pump 5, and casing is provided with the access door 20 that can open and close.Be provided with water-locator 6, evaporimeter 4 and water leg 9 in the spraying box from top to bottom successively, be provided with wastewater trough 10 in the waste water tank, water-locator 6 links to each other with wastewater trough 10 by circulating pump 5, and the evaporimeter 4 in the spraying box links to each other with condensation unit 3 by refrigerant tubing; The position of the water leg 9 of spraying box outer surface is equipped with inverted U-shaped bend pipe 8 and overflow pipe 11, be provided with communicating pipe between the two ends of inverted U-shaped bend pipe 8, be respectively equipped with valve 7 and control valve 12 on communicating pipe and the overflow pipe 11, water leg 9 links to each other with wastewater trough 10 by overflow pipe 11; The bottom of the outer surface of waste water tank is provided with tapping pipe 14, and tapping pipe is provided with valve 15.Condensation unit 3 includes compressor 17, condenser 16, expansion valve 18, power distribution cabinet 19, refrigerant tubing.The pipeline of collecting waste water links to each other with treatment device for water 1, and treatment device for water 1 links to each other with wastewater trough 10.Water leg 9 and wastewater trough 10 have insulation construction, and the outer surface of waste water tank is provided with liquid level gauge 13.
During this device work, waste water enters treatment device for water 1, flows into wastewater trough 10 after water treatment.Circulating pump 5 is evacuated to the waste water in the wastewater trough 10 water-locator 6 of evaporimeter 4 tops, waste water is sprinkled upon equably on the horizontal heat exchange tube of evaporimeter 4 by water-locator 6, form the liquid film of past current downflow on the surface of heat exchanger tube, carry out heat exchange with the cold-producing medium in the heat exchanger tube, the waste water after the heat release flows into water leg 9.Low-temperature low-pressure refrigerant liquid in the evaporimeter 4 absorbs the heat of vaporization of waste water, the gas that the evaporation back forms enters the compressor 17 of condensation unit 3, become high temperature and high pressure gas after the compression, condensation heat release in the condenser 16 of condensation unit then, liberated heat is with the water inlet heating of condenser 16.Condensed refrigerant liquid becomes the refrigerant liquid of low-temp low-pressure through behind the expansion valve 18, and evaporation so circulates in the refrigerant liquid inflow evaporator 4 of these low-temp low-pressures.
When the water level of water leg reached the position of overflow pipe 11, unnecessary water can flow out from inverted U-shaped bend pipe 8 and overflow pipe 11 simultaneously.Directly drain from the water that inverted U-shaped bend pipe 8 flows out, it is recycling that the higher relatively superficial water of water temperature enters wastewater trough 10 from overflow pipe 11 outflows.When wastewater flow rate is bigger, when the water level in the waste water tank reaches warning line, regulate flow in the overflow pipes 11 by control valve 12.
When this device is not worked, can open valve 7 on the inverted U-shaped bend pipe 8 and the valve 15 on the tapping pipe 14, the waste water in water leg 9 and the wastewater trough 10 are drained.When this device needs maintenance or cleaning, can open access door 20.When cleaning the horizontal heat exchange tube of evaporimeter 4, can adopt following method: open the valve 7 on the inverted U-shaped bend pipe 8, cleaning fluid is poured in the empty wastewater trough 10, utilize circulating pump 5 that cleaning fluid is evacuated to water-locator 6, cleaning fluid evenly is sprayed on the heat exchanger tube of evaporimeter 4 by water-locator 6, the cleaning fluid that cleaned behind the dirt flows out, and also cleaning fluid can be introduced wastewater trough 10 and recycle.
This device is a kind of standardization, modular unit, can select the unit of different sizes according to the flow of different occasion waste water for use, can many in parallel uses of unit.The occasion of or concentrated waste discharge big for wastewater flow can be provided with the balancing tank.
