Abstract
The utility model relates to a device for recovering waste heat from flue gas of a combustion furnace. The upper part of a combustion chamber of a combustion furnace and an inlet of flue gas of a flue are respectively provided with a super-heat conducting pipe, wherein, the other end of which is inserted in a heat exchanger, wherein, the top part and the lateral wall of which are respectively provided with a hot water outlet and a hot water return pipe, and the lower part of which is provided with a cooling water inlet. The utility model uses the super-heat conducting pipe to thoroughly recover residual heat in flue gas, and the residual heat can be utilized again. Energy can be saved, regenerated heat energy can be created, the degree of environmental cleaning can be improved, and air pollution can be reduced.
Description
The utility model relates to a kind of super heat-conductive pipe that utilizes and carries out combustion furnace flue waste heat recovery plant.
Flue gas is in when discharging, also corresponding quite a few heat of having taken away; Wherein coal furnace loses heat in flue accounts for 30% of its total heat energy, and 20% heat-energy losses of losing minimum gas furnace that the oil burner loss accounts for its total heat energy also accounts for 15% of its total heat energy.Thereby people manage to reclaim fume afterheat; Various flue gas waste heat recovery apparatus are a lot, but recovery utilization rate is all very not high, still have a lot of heat energy to be discharged in the air by flue and slattern.
The purpose of this utility model is to utilize super heat-conductive pipe all to reclaim the waste heat in the flue gas and utilized again in order to provide a kind of, can save the energy and create regenerated heat energy, also can improve depollution of environment degree, reduces the combustion furnace fume waste heat retracting device of atmosphere pollution.
The purpose of this utility model can realize by following measure:
A kind of combustion furnace flue gas retracting device above the combustion chamber of combustion furnace and the gas approach place of flue be placed with super heat-conductive pipe, the other end of super heat-conductive pipe inserts in the heat exchanger, be respectively equipped with hot water outlet and hot water return pipe at heat exchanger top, sidewall, be provided with cooling water inlet in the bottom of heat exchanger.
The utility model has following advantage compared to existing technology:
The flash heat transfer performance that the utility model utilizes super heat-conductive pipe reclaims the fume waste heat at top, combustion chamber and chimney intake place fully and drops into again and utilizes, and has greatly saved the energy and has created regenerated heat energy, also can improve depollution of environment degree, the minimizing atmosphere pollution; The utility model is simple and easy to do, low cost of manufacture.
Concrete structure of the present utility model is provided by the following drawings:
Fig. 1 is a structural representation of the present utility model
1-combustion furnace 2-combustion chamber 3-flue 4-super heat-conductive pipe 5-heat exchanger
6-hot water outlet 7-hot water return pipe 8-cooling water inlet
The utility model is also incited somebody to action in conjunction with the accompanying drawings, and embodiment is described in further detail:
With reference to Fig. 1, a kind of combustion furnace fume waste heat retracting device is above the combustion chamber 2 of combustion furnace 1 and the gas approach place of flue 3 is placed with super heat-conductive pipe 4, the other end of super heat-conductive pipe 4 inserts in the heat exchanger 5, be respectively equipped with hot water outlet 6 and hot water return pipe 7 at heat exchanger 5 top sidewalls, be provided with cooling water inlet 8 in the bottom of heat exchanger 5.Described super heat-conductive pipe 4 forms for hollow tube vacuumizes back adding heat-conducting medium.Its operation principle be by super heat-conductive pipe 4 with the fume waste heat of flue 3 import departments of 2 tops, combustion chamber of combustion furnace 1 with receiving to heat exchanger 5, produce hot water by the top of heat exchanger 5 and flow out through hot water outlet 6, its backwater is entered by the hot water return pipe 7 of its sidewall; Cooling water inlet 8 by the bottom of heat exchanger 5 replenishes cold water.
