Abstract
The utility model relates to a high efficiency waste heat exchanger, which is characterized in that a heat exchanging box body which is connected with a connecting tube and is supported by a support plate is arranged above a heating box body; four to six groups of serpentine heat exchanging tubes which are supported by a support tube, are arranged in the heat exchanging box body, and both ends of each group of serpentine heat exchanging tubes are respectively communicated with a cold water tube and a hot water tube. The end head of the heating box body is provided with a flue connecting tube; the position of a water filling tube on the flue connecting tube is provided with an explosion preventing valve. The high efficiency waste heat exchanger has the advantages that high efficiency waste heat exchanger can conduct heat exchange with low temperature, flue gas of 400 DEG C can conduct the heat exchange, and the heat efficiency is high, and a protective device is installed. The utility model also has the advantages of zero pressure operation, safety, simple structure, small occupation area and convenient repair. The utility model is suitable for being used as a flue waste heat exchanger.
Description
The utility model belongs to the retracting device of Industrial Stoves, boiler emission fume afterheat, and particularly a kind of flue passes through the efficient afterheat heat exchanger of heat exchanger.
The temperature of Industrial Stoves, boiler emission flue gas is very high, and accumulating has a large amount of heat energy, can pass through heat-exchanger rig, with heat recovery.Existing flue gas waste heat recovery apparatus mostly is the outlet place that is installed in flue heat exchanger is set, and with the heat transferred water body of flue, draws utilization by pipeline.Because the flue limited length, the waste heat recovery amount is less.
The purpose of this utility model is, designs and produces a kind of efficient afterheat heat exchanger, flue was walked water container after, utilize flue gas heat that cold water is heated into steam; By snakelike heat exchange tube, utilize the heat heating cold water of steam again, realize the secondary exchange, make heat exchange abundant, further improve heat exchange efficiency.
Efficient afterheat heat exchanger of the present utility model, by the heating casing, defeated smoke pipe, water injection pipe, blow-off pipe is formed, and it is characterized in that, above the heating casing, by connecting tube connection, support plate rest the heat exchange casing is arranged; Be provided with 4～6 groups of snake dish type heat exchanger tubes of support column rest in the heat exchange casing, every group of snake dish type heat exchanger tube two ends are connected with cold water pipe, hot-water line respectively; Be provided with gate in heating casing termination, flue tube connector and ash releasing tube constitute the heat control section; The water injection pipe place is provided with explosion-proof valve in connecting tube, in heat exchange casing termination Pressure gauge and pressure-reducing valve is set, and constitutes the protective device of zero-pressure operation.
Using method of the present utility model is that efficient afterheat heat exchanger is installed on the flue collector or residual heat flue of Industrial Stoves, boiler.During work, cold water is added in the heating casing water and,, stop to add water to the peephole place highly for above all defeated smoke pipes by water injection pipe; Starting gate, flue gas enter in the defeated smoke pipe through gate, flue tube connector, drill tube connector by opposite side at last and discharge; In the flow through process of defeated smoke pipe of flue gas, the cold water in the heating casing is heated to boiling, the water vapour of generation enters the heat exchange casing through connecting tube, heats the cold water in the heat exchanger tube; Start the external equipment water pump, water is added cold water pipe, through cold water pipe, cold water enters snake dish type heat exchanger tube and is heated into hot water by water vapour, and hot water is pooled to hot-water supply main through hot-water line, reaches the purpose of waste heat recovery; Behind this cold water, disengaged vapor heat-transmission of water vapour heating heat exchanger tube, the hot water that is condensed into 100 ℃ flows back to the heating cabinet body, has guaranteed the water yield in the heating casing and the fluidized state of water.Explosion-proof valve and pressure-reducing valve have guaranteed that efficient afterheat heat exchanger operates in zero-pressure.
The utility model has the advantages that can carry out low-temperature heat exchange, 400 ℃ flue gas just can carry out heat exchange, thermal efficiency height; Protective device is installed, the zero-pressure operation, safe and reliable; Simple in structure, floor space is little, and is easy to maintenance; Applied widely, be applicable to the feed-water heater that flue residue heat is recycled.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of efficient afterheat heat exchanger
Fig. 2 is the A-A profile of Fig. 1
As seen from the figure, efficient afterheat heat exchanger of the present utility model, by heating casing 1, defeated smoke pipe 2, water injection pipe 3, blow-off pipe 4 is formed, and it is characterized in that, above the heating casing, by connecting tube 5 connections, support plate 6 rests heat exchange casing 7 is arranged; Be provided with 4～6 groups of snake dish type heat exchanger tubes 9 of support column 8 rests in the heat exchange casing, every group of snake dish type heat exchanger tube two ends are connected with cold water pipe 10, hot-water line 11 respectively; Be provided with gate 12, flue tube connector 13 and ash releasing tube 14 in heating casing termination; Water injection pipe place in connecting tube is provided with explosion-proof valve 15, in heat exchange casing termination Pressure gauge 16 and pressure-reducing valve 17 is set, and constitutes the protective device of zero-pressure operation.
