Description

A kind of in-flow baking oven

Technical field

The utility model relates to a kind of baking heating stove being applicable to fruits and vegetables baking, Chinese medicine baking, bulk curing barn tobacco flue-curing, belongs to baking, drying facility technical field.

Background technology

The agricultural byproducts baking oven extensively adopted at present is all the mode of external heat exchange, that is, bottom is burner block, and top is the heat-exchanger rig of heat exchanger tube composition.The baking oven of this structure all exists and makes the excessively slow problem of complexity, the heat exchange efficiency inclined end, temperature rise rate.Just there is this problem in the energy-saving hot blast furnace in patent 01228210.3, heat exchange structure makes complicated, and manufacturing cost is expensive, hot blast stroke is long, the circulating fan power needed is comparatively large, the more difficult cleaning of the impurity that the high-temperature flue gas in practical work process carries, thus easily blocks heat exchange pipeline.

Summary of the invention

The purpose of this utility model is to provide a kind of in-flow baking oven, and compared with conventional oven, this Roaster structure is simple, not easily blocks heat exchange pipeline, can realize saving fuel more than 20%, can reduce Air Pollutant Emission more than 30%.

realizing the technical scheme that the utility model above-mentioned purpose takes is:one urceolus is set outside stove cylinder, interlayer between stove cylinder and urceolus is provided with dividing plate and is separated into hot air chamber and cold air chamber, the hot-blast outlet of hot air chamber bottom establishes circulating fan, hot air chamber top heat exchanger tube and cold air chamber connect, cold air chamber's upper entrance leads to air, the outlet flue of stove cylinder is located at the top of more than hot air chamber and leads to air by air blast and stovepipe, the combustion chamber on burner hearth and deashing chamber indirect wildcard wind passage.

Described air distribution passage is more than two secondary aid distributing pipes, and secondary aid distributing pipe is arranged on the outside of the refractory brick section excircle of burner hearth with equispaced.

Described air blast is arranged on outlet flue and the stovepipe delivery position of stove cylinder, and blower export is consistent with stovepipe Way out; Hot-blast outlet is arranged on hot air chamber bottom just to the position of deashing chamber.

The stove cylinder of body of heater overlaps with the center line of urceolus.

This baking oven have employed the vertical two-layer chuck interior stream heat exchange mode of simple structure, and burner hearth and heat pipe whole body structure, promote heat exchange area to greatest extent in limited space, thus improves heating rate, reduction manufacturing cost.

While the air blast of use negative pressure, coordinate secondary air distribution to carry out half gasification, and combustion, sufficient combustion, obviously promote the heat exchange efficiency of high-temperature flue gas and heat pipe.The natural air that outside enters is entered hot blast chuck cold air chamber and washes away after stove cylinder carries out elementary preheating and flowed out by inner-heating tube, again enters hot blast chuck hot air chamber and carries out post bake, realize being rapidly heated.Meanwhile, the burner hearth of this in-flow baking oven is arranged on the most crucial internal layer of body of heater, and top is provided with heat exchanger tube, and outside all has natural air to surround, and makes air heat-exchange efficient in time.

Because heat exchange is abundant, stove cylinder border, heat pipe are all subject to good natural air and wash away, thus effectively raise the service life of stove cylinder, the maintenance cost in reduction process, thus realize efficient, energy-saving and environmental protection, reduce manufacturing cost and manufacture difficulty to greatest extent.

Advantageous Effects of the present utility model is: adopt air blast tangential induced air to produce negative pressure, and flue gas flow direction is stablized, thus improves its working environment, raising service life of fan.Adopt half gasification second-time burning mode, effectively avoid the generation of tar, thus stop to be formed outlet flue in flue gas transmitting procedure to block.Heat exchange jacket makes natural air heat exchange efficiency promote, and controls air flow by force, improves hot-air heating rate.For effectively improving fuel availability, improving tail gas environmental-protecting performance, stove cylinder top is provided with combustion combustion space, room and inner-heating tube, the flue gas, dust and the fuel gas that produce through primary combustion thoroughly can burn further in these indoor after secondary air distribution, realize the object of clean emission.For avoiding grate to be in hot environment for a long time, adopting top side smoke mode, because flue gas does not pass through grate but side, furnace wall above grate is drawn, inside stove cylinder, being provided with refractory brick, stove cylinder and grate service life can be guaranteed.

Fig. 3 is plan structure schematic diagram of the present utility model.

In figure, each label represents successively: urceolus 1, stove cylinder 2, hot air chamber 3, cold air chamber 4, heat exchanger tube 5, dividing plate 6, refractory brick 7, coal filling hole 8, grate 9, deashing chamber 10, cleaning door 11, combustion chamber 12, stovepipe 13, outlet flue 14, air distribution passage 15, secondary aid distributing pipe 16, hot-blast outlet 17, air inlet 19, air blast 20, circulating fan 21, body of heater 22.

Detailed description of the invention

See each figure.This device is arranged on machine 19 and circulating fan 20 4 part composition primarily of body of heater 22, stovepipe 13, air blast.The urceolus 1 of body of heater 22 surrounds stove cylinder 2, between hot blast dividing plate 6 urceolus 1 and stove cylinder 2, constitutes hot air chamber 3 and the cold air chamber 4 of separation.Be positioned at the cleaning door 11 of lower portion of furnace body, space that grate 9 surrounds with body of heater 22 constitutes deashing chamber 10.Be positioned at the coal-fired section that the coal filling hole 8 in the middle part of body of heater, refractory brick 7 and body of heater 22 form combustion chamber 12.Cold air chamber 4 is communicated with by the top of heat exchanger tube 5 at interlayer with hot air chamber 3.The outer circumference outer rim being positioned at body of heater middle and lower part refractory brick 7 is provided with secondary aid distributing pipe 16, is communicated with by deashing chamber 10 with combustion chamber 12.Be positioned at stove cylinder 2 top and be provided with outlet flue 14, flue gas is expelled to air by stovepipe 13 and air blast 20.Outside natural air enters into cold air chamber 4 by circulating fan 21 negative pressure from air inlet 19, flows to hot air chamber 3, send follow-up baking box dry eventually through hot-blast outlet 17 and circulating fan 21 by heat exchanger tube 5.

Utility model works process is such:

Under air blast 20 acts on, negative pressure is produced in combustion chamber 12, extraneous air enters deashing chamber 10 by cleaning door 11, air burns through grate 9 and the coal added from coal filling hole 8, simultaneously, partial air enters into refractory brick more than 7 space of combustion chamber 12 through secondary aid distributing pipe 16 entrance being positioned at deashing chamber 10, and be mixed to form second-time burning with remaining fuel gas, the high definition flue gas burning most flows through outlet flue 14 by the outlet flue 14 on stove cylinder 2 top and stovepipe 13 is discharged to air.Namely the stove cylinder 2 of centre, heat exchanger tube 5 are heated in cyclic process at whole flue gas.

Under circulating fan 21 suction function, outside natural air enters into cold air chamber 4 by circulating fan 21 negative pressure from air inlet 19, flows to hot air chamber 3 by heat exchanger tube 5, sends follow-up baking box dry eventually through hot-blast outlet 17 and circulating fan 21.
