Abstract

The utility model provides a hot pipe heater with waste heat of the flue gas as fuel, belonging to the category of heating devices. The utility model has a hot pipe heat exchanger arranged at the side of the flue with the hot pipe heat absorbing section of the hot pipe heat exchanger inserted in the flue and the hot pipe heat release section inserted in hot pipe heat exchanger. Each hot pipe heat release section is enclosed by casing and the front and tail ends of each casing communicate sequentially. Collecting ducts connect horizontally all ends of each group of casing that stretch outside the heat exchanger. The flue and hot pipe heat exchanger are sealed and separated by a diaphragm between them. The advantages of the utility hot pipe heater with waste heat of flue gas as fuel include the reasonable design, little flue gas resistance, and difficult accumulation of dust, reliable and safe service, long service life, large heat exchange area, rapid heat transfer and high efficiency of heat exchange.

Description

Heat pipe-type fume afterheat fuel heater
Technical field
The novel heater that belongs to of this reality, particularly a kind of heat pipe-type fume afterheat fuel heater.
Background technology
Heat pipe is a kind of heat transfer element with superior heat conductivity energy.It transmits heat by the latent heat that phase transformation produced of working media in managing.Therefore, its heat-transfer capability is big, heat transfer efficiency is high, is an efficient heat transfer achievement of heat transfer technology.But the heat transfer area that it has high thermal conductivity, good isothermal, cold and hot both sides can change series of advantages such as remotely transferring, temperature controllable arbitrarily.
The heat pipe-type fume afterheat fuel heater of forming by heat-pipe elements have heat transfer efficiency height, compact conformation, fluid resistance little, help controlling dew point corrosion, cold and hot body separately, do not need advantage such as power.Can be widely used in the industries such as metallurgy, chemical industry, oil refining, boiler, pottery, traffic, light textile, machinery, as the energy-saving equipment of heat energy utilization in Waste Heat Recovery and the technical process.Yet the fuel oil of existing fuel oil heating all needs so not only to expend a large amount of energy in independent preheating, has increased the equipment and the running cost of device.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and the heat pipe-type fume afterheat that a kind of thermal conductivity is good, the thermal efficiency is high fuel heater is provided.
Heat pipe-type fume afterheat fuel heater of the present utility model is in the flue side heat exchange of heat pipe to be installed, and the heat pipe heat-absorbing section in the heat exchange of heat pipe is implanted in the flue, heat pipe heat release section is implanted in the heat exchange of heat pipe.Each heat pipe heat release section all has sleeve pipe outward, and initial and end is connected between each sleeve pipe, and all there is the concetrated pipe lateral direction penetrating termination that extends to outside the heat exchanger at each group sleeve pipe two ends.Between flue and heat exchange of heat pipe, the dividing plate that both is sealed mutually partition is arranged.
As further improvement of the utility model, on the outer wall of heat pipe heat-absorbing section, be wound with fin, and filled insulation material in the interior space of heat exchange of heat pipe.
Its operation principle of heat pipe-type fume afterheat fuel heater of the present utility model: with oil pump fuel oil is extracted out from oil tank, the heater via feed line arrives heat pipe-type fume afterheat fuel heater.After the heat exchange, via the burner boiler of feeding burning before the heater flow line arrival oil burning boiler.On the heater flow line, establish simultaneously the oil return pipeline, will be transported the oil return jar, improve the oil tank temperature, prevent that fuel oil from solidifying by the unnecessary fuel oil after the heating of heat pipe-type fume afterheat fuel heater.Between heater feed line and flow line, establish normally closed bypass pipe, and electric heater or steam heater are set on the heater flow line, as the interim heater before the boiler startup.Whole process flow reaches following purpose: under the situation about just light a fire at boiler, the boiler smoke temperature is lower, the work of the alternative heat pipe-type fume afterheat of interim heater fuel heater is arranged; Fuel oil part after the heating is for the oil burning boiler burning, and another part can be got back to oil storage tank and improve a jar intermediate fuel oil temperature, prevents that it from solidifying.
Its advantage of heat pipe-type fume afterheat fuel heater of the present utility model is: reasonable in design, flue gas resistance is little, be difficult for dust stratification dirt, security is good, the life-span is long, heat exchange area is big, heat transfer is fast, heat exchange efficiency is high.
Description of drawings
Figure of description is the structural representation of heat pipe-type fume afterheat fuel heater of the present utility model.
The specific embodiment
Heat pipe-type fume afterheat fuel heater of the present utility model is in flue 1 side heat exchange of heat pipe 2 to be installed.Be wound with fin 8 on the outer wall of the heat pipe heat-absorbing section 3 in the heat exchange of heat pipe 2 and heat pipe heat-absorbing section 3 is implanted in the flues 1, heat pipe heat release section 4 is implanted in the heat exchange of heat pipes 2.Outside each heat pipe heat release section 4 sleeve pipe 5 is arranged all, 5 initial and ends of each sleeve pipe are connected, and all there are concetrated pipe 6 lateral direction penetratings the termination that extends to outside the heat exchanger 2 at each group sleeve pipe 5 two ends; Between flue 1 and heat exchange of heat pipe 2, the dividing plate 7 that both is sealed mutually partition is arranged.
Heat insulating pearlite material 9 has been filled in interior space at heat exchange of heat pipe 2.
Cold fluid and hot fluid separates fully during heat pipe-type fume afterheat fuel heater heat exchange of the present utility model, relies on the working media of inside heat pipe to carry out heat exchange, even fuel leakage can not enter flue yet and cause the accident.Simultaneously, on heat pipe heat-absorbing section 3 outer walls fin 8 is arranged, increased heat exchange area, compare with the other types heater with volume, the heat exchange amount improves 4 times.With dividing plate 7 sealings, strengthen security in the middle of the heat pipe-type fume afterheat fuel heater cold junction hot junction; Heat pipe-type fume afterheat fuel heater cold junction adopts bushing type to conduct heat, and improves flow velocity, improves the heat pipe utilization rate; Heat pipe is arranged as along row in the heat pipe-type fume afterheat fuel heater, and flue gas resistance is little, is difficult for dust stratification; The fuel oil heat exchange of heat pipe adopts the countercurrent flow form, improves heat exchange efficiency.
Heat pipe-type fume afterheat fuel heater of the present utility model, the user can use many heat pipe-type fume afterheat fuel heaters as required simultaneously, adopts with the journey design when using simultaneously.
