Overhead air suction type heat exchanger structure

 

Technical field

The invention belongs to biological particles fireplace, biomass granule boiler, biological particles warmer field, relate to a kind of overhead air suction type heat exchanger structure.

Background technology

In heating system, air-conditioning, electric furnace, gas pipeline, charcoal burner etc. are arranged, and the heating method that the country variant different regions adopt in the winter is different, and every kind of equipment has features, fireplace on market is used combustion gas and electric power mostly, also has and uses charcoal and utilize solar energy.

Because the electric fireplace of simulated fire series, do not reach the genuine article effect when cold in winter, the firebrand fireplace that some are traditional, efficiency of utilization is very low, and air is had to pollution, and gas firing wall is with non-renewable energy resources such as natural gas, also defectiveness.Therefore, utilize the burning of the particles such as wood, stalk, cornstalk, rubbish to produce heat energy and the hearth particle that reaches heating effect has just arisen at the historic moment.

Existing biological particles fireplace generally adopts underlying blowing-type heat exchanger structure, air-heater is placed in to the middle and lower part of burner hearth, and hot-blast outlet is at the top of burner hearth, and air-heater is blown into heat exchanging air duct by outside air, from hot-blast outlet, blows out, and realizes heat exchange.Above-mentioned heat exchange structure is used for many years, but still comes with some shortcomings, and is mainly manifested in: 1, heat exchanger is inevitable to the windage of hot blast, for reducing windage, will inevitably sacrifice the heat exchange exchange area; 2, heat exchange efficiency is not high, owing to must guaranteeing enough heat exchange areas, causes producing windage, and the hot blast air quantity has very big loss; 3, fan noise is excessive.Because heat exchanger has larger windage, inevitably make hot air duct produce and utter long and high-pitched sounds.

Therefore, how addressing the above problem, is the content that the present invention will study.

Summary of the invention

In order to overcome above-mentioned deficiency of the prior art, the invention provides a kind of overhead air suction type heat exchanger structure.

For achieving the above object, the technical solution used in the present invention is: a kind of overhead air suction type heat exchanger structure comprises cabinet, air-heater, Cryogenic air air inlet pipe and feed appliance assembly; Be provided with combustion chamber in described cabinet; Described Cryogenic air air inlet pipe is two, is separately positioned on the both sides of cabinet inside by combustion chamber; Also comprise heat exchanger heat collector, high-temperature heat exchange tube and smoke evacuation heat exchanger tube; Described heat exchanger heat collector is arranged on the top of combustion chamber, and this heat exchanger heat collector is provided with the air-heater air entry; Described high-temperature heat exchange tube is a plurality of, is arranged on side by side heat exchanger heat collector inside apart; Described air-heater also is arranged on the top of combustion chamber, and corresponding described air-heater air entry arranges; Described smoke evacuation heat exchanger tube is the inverted U pipeline, and described smoke evacuation heat exchanger tube is arranged on back and the both sides of combustion chamber, and its dual-side pipeline is separately positioned on the inboard of described Cryogenic air air inlet pipe.

In such scheme, related content is explained as follows:

1,, in such scheme, described feed appliance assembly main fuel charging aperture, fuel cassette and fire rod form.

2, in such scheme, on described each Cryogenic air air inlet pipe, be equipped with air inlet and gas outlet, wherein, described air inlet is arranged on the opening below of the described cabinet outside near combustion chamber; Described gas outlet is arranged on the opening top of the described cabinet outside near combustion chamber.

3,, in such scheme, described high-temperature heat exchange tube is at least four.

4, in such scheme, described smoke evacuation heat exchange pipeline is two groups, and front and back are set up in parallel in the back of described combustion chamber and both sides.Described smoke evacuation heat exchange pipeline is the cylindrical shape type.

Operation principle of the present invention: air-heater is placed in to the top of combustion chamber, makes heat exchanger air channel distance the shortest, guarantee the windage minimum; Thereby guarantee that the air-heater noise is less than 42dB; The Cryogenic air air inlet pipe lengthens again, can extend the holdup time of cold air in the Cryogenic air air inlet pipe, smoke evacuation heat exchanger tube heat exchange through the back side, combustion chamber, improve the temperature of air-heater air amount, the hot-air that air-heater sucks directly enters in the thermal-arrest heat exchanger of top of combustion chamber, making thermal-arrest heat exchanger surface temperature is the maximum temperature in combustion chamber, is about 350 degree.

Because technique scheme is used, the present invention compared with prior art has following advantages:

1, due to structure of the present invention, air-heater is placed in to the top of combustion chamber, makes heat exchanger air channel distance the shortest, guarantee the windage minimum; Thereby guarantee that the air-heater noise is less than 42dB.

2, because structure of the present invention lengthens the Cryogenic air air inlet pipe, can extend the holdup time of cold air in the Cryogenic air air inlet pipe, smoke evacuation heat exchanger tube heat exchange through the back side, combustion chamber, heat conduction by cold and hot air, can raise the fast temperature of air-heater air amount, the hot-air that air-heater sucks directly enters in the thermal-arrest heat exchanger of top of combustion chamber, improves heat transfer efficiency, making thermal-arrest heat exchanger surface temperature is the maximum temperature in combustion chamber, is about 350 °.
