Utility model architectural feature, technical characteristic and the technique effect for bringing are described in detail as follows：

Utility model has " high and big vertical furnace chamber " architectural feature.Utility model furnace chamber is tall and big, furnace chamber volume Greatly, combustion space effective rate of utilization is high, then can load more fire coals, and realization is disposably coaling, and mitigates operative employee's labor intensity.Such as Shown in accompanying drawing 3, long 1.4m, 0.73m width of continuous tunnel furnace burner hearth, 0.9m are high, and coal bed has in highly there was only 600mm, and coal bed cannot The uneven gap for avoiding, combustion space effective rate of utilization can only load local life beehive coal ball 800～1000 less than 80% Individual (single coal briquette high 75mm), can meet needs of disposably coalingging in theory.Due to body of heater accumulation of heat it is many, fire door radiant heat loss Greatly, flue gas CO discharges are more, and the thermal efficiency is low, and coal consumption is big, and 800～1000 coal briquettes tend not to meet baking needs, are exactly fine Its room middle leaf is toasted 5～6 days, and as many as coal 1～3 time also want in centre, it is difficult to realize target of disposably coalingging, not to mention When rainy day and upper leaf are toasted, midway needs to add coal briquette number of times.2 cavity heights 1.2m of utility model bosh～1.5m, the length of side 0.8m～1.0m, between Honeycomb coal briquet 5, gapless, briquet 5 are little to 5mm～10mm with 2 internal face gap of bosh, and combustion space has Effect utilization rate reaches 100%, coal bed up to 2 top end face of bosh, disposable coal capacity and continuous tunnel furnace quite, and utility model thermal effect Rate is higher by continuous tunnel furnace 25%, and natural energy of disposably coalingging is kept for the longer combustion heat supplying time.Cigarette is filled slightly above 2.5 in barn Utility model is used under the conditions of ton, rainy day harvesting and upper tobacco leaf, without midway deashing coal, accomplishing disposably to coaling completes 6 ～7 days baking combustion heat supplying tasks.

Utility model has that " vertical furnace chamber, high furnace chamber, coaling passage and deashing passage unites two into one, and operation is logical The architectural features such as high, the high fire door 4 of road height ".As shown in Figure 3, continuous tunnel furnace coal piling area, collect gray area, channel lumen of coalingging, clear Grey channel lumen unification, without fire bars, fire door only has 560mm high, and operative employee can only contact to earth to creep and enter furnace chamber, then pedal entirely and move back Row is banked up coal briquette, furthermore width is little, space is little, and highly short, air flow is not smooth, and appearance is to a certain degree felt oppressed sense, operation of coalingging It is uncomfortable, it is difficult to meet hole device to hole, with seamless requirement between adjacent two coal briquette of row of horizontal.Utility model vertical type burner hearth, heap Coal area collection gray area on, eliminate towards coal piling area coaling passage and towards collection gray area deashing passage between common wall Plate, coalings passage and deashing passage is merged into operating walk way, operating walk way cavity heights and 4 height of fire door be up to 1.2m～ In posture turnover furnace chamber of slightly pedaling or slightly bend over, 1.5m, operative employee can add that thorax in stove is tall and big, air flow is smooth, will not There is sense of feeling oppressed, operative employee is gone slick in furnace chamber, realization is comfortably coaling, the coal piling such as hole device to hole and briquet gapless is required Easily with satisfaction.

Utility model has " L-shaped light-duty fire door 4 " architectural feature.4 flame-retardant fibre board of utility model fire door is used for sealing Operating walk way right output port, prevents outside air to penetrate into 2 inner chamber of operating walk way and bosh, and 4 flame-retardant fibre board bottom of fire door is stretched Exhibition body left side and 2 side wall of bosh together, surround the static pressure area of closing, and cut-out static pressure area combustion air bypass flow to operating walk way The passage of 2 inner chamber of inner chamber and bosh.Fire door 4 meets seal operation passage right output port and static pressure area breach simultaneously, there is provided furnace temperature The essential condition of auto-control.Fire door 4 be up to 1.2m～1.5m, structure bulky is caused using castable refractory, coaling deashing when 4 switching manipulation difficulty of fire door increases, and fire door 4 includes flame-retardant fibre board, alleviates fire door weight, is that fire door 4 easily fills in pull-out Light operation is there is provided probability.

Utility model has " closed static pressure area " architectural feature.Continuous tunnel furnace static pressure area is in unenclosed construction.Such as 3 institute of accompanying drawing Show, vacate the region as static pressure area that 2～3 floor coal briquette are vacated when continuous tunnel furnace coal piling is to entrance point fire door, due to burner hearth coal piling extremely High to 0.6m, furnace roof internal face to the height space of about 130mm between coal bed top surface has become air by-pass and has rapidly flowed to smoke evacuation The passage of mouth, i.e. static pressure area top surface is unlimited.Bosh 2 inner chamber of the utility model fire bars below 3 is static pressure area.Due to fire door 4 The seamless connection in gathering hole edge below 3 of body left side edge and fire bars is stretched in flame-retardant fibre board bottom, and static pressure area side wall is closed, By fire bars 3, all uniform flow enters the numerous thin bar shape gas channels of coal bed to the air that blower fan is blasted in static pressure area upwards, is stove Warm auto-control establishes condition.

Utility model architectural feature " high and big vertical furnace chamber " can guarantee that, meet nowadays countryside labour force Market demand.Architectural feature " high and big vertical furnace chamber, coaling passage and deashing passage unites two into one, operating walk way height is high, High fire door 4 " can guarantee that coalings deashing operation comfortably, and people-oriented to accomplish tobacco flue-curing.Architectural feature is " vertical furnace chamber, short Fire door 4, closed static pressure area " is the precondition of " flowing heat transfer combustion process is scientific and reasonable in stove ".

Caused by " vertical type furnace chamber, the closing of static pressure area " architectural feature, one of technical characteristic is " open fire reverse combustion ".Tunnel Stove dying fire is just burning heat supply.As shown in Figure 3, continuous tunnel furnace from coal bed downstream, ignite by igniting, and blower fan drives air to coal bed oblique upper Direction is flowed, and burns towards coal bed oblique upper direction and moves, meets dying fire and just burning principle, and the coal bed in combustion front oblique upper is received To high-temperature baking, in coal bed, carbonization gas, volatile matters are together with high temperature CO₂Gas contact high-temperature coke is reduced the CO gases one of generation Rising, coal bed being flowed out to coal bed oblique upper direction, final Jing exhaust openings scatter and disappear, the thermal efficiency as little as 50% or so.It is even more important , the CO air-flows of discharge have interior heat energy, and combustion heat release amount is reduced, and combustion heat release amount does not reach maximum, and content of CO in smoke is not The air mass flow for stably directly resulting in combustion heat release amount and participating in combustion reaction is not directly proportional, and increases and is adjusted with air mass flow automatically The difficulty of control furnace temperature process.Utility model enters static pressure area, static pressure area side wall and base plate No leakage by the air that blower fan drives, and helps It is bottom-up uniformly across coal bed that combustion air completely extends across fire bars 3.Whole air flow uniformly through coal bed with piston stream mode, from coal Bed end face center starts igniting and ignites, and combustion front is from up to down slowly moved, combustion front moving direction and air-flow direction phase Instead, realize open fire reverse combustion heat supply.When combustion front is moved down, the bottom coal briquette and air for contacting, briquet preheating is constantly preheated When the carbonization gas that formed enter combustion front complete combustion reaction occur, leave the high temperature CO of combustion front₂Do not have when gas is flowed up There is high-temperature coke to contact, i.e. life does not become reducibility gas CO, and so discharge fume CO₂Gas content is high, CO gas contents pole It is low.So, combustion heat supplying process energy conservation, the discharge of low stain thing is realized, what is more important smoke evacuation is without interior heat-energy losses, burning Thermal discharge reaches maximum, and exothermic maximum amount and air mass flow are directly proportional, and is to be created favorably with air regulation furnace temperature process Condition.Usually, open fire reverse combustion technology is just for graininess, block bituminous coal cleaning combustion purpose, domestic honeycomb coal combustion dress Put and use anthracite, make beehive coal ball, and just burning based on dying fire that principle person is in the majority, be applied to the nothing based on open fire reverse combustion principle Bituminous coal Honeycomb coal briquet burner report is extremely rare.

Caused by " vertical furnace chamber inner chamber, closed static pressure area " architectural feature, the two of technical characteristic are that " furnace temperature is adjustable can Control ".How many Combustion of Hot Air Furnace heat releases is proportional to the air mass flow size for participating in combustion reaction.The air that operating walk way inner chamber is detained Can bypass and flow to exhaust opening, and then reduce air effective rate of utilization, reduce regulatory function of the air mass flow to combustion heat release amount.It is real Closed with novel static nip, whole air are uniformly flowed up in piston flow shape in coal bed, without behaviour of the air Jing fire bars below 3 Bypass to operating walk way region as mouth.Although in gathering hole directly contact operating walk way of the coal piling area coal bed by fire bars more than 3 Chamber, but air is when coal bed is walked, coal bed gas channel and exhaust opening negative pressure formed be drawn up power, static pressure area static pressure formed to Upper flowing driving force and high-temperature flue gas density form the air flows upwards that buoyancy lift causes in coal bed upwards, and horizontal direction flows out The air capacity in coal bed to operating walk way region is negligible.Final whole air passes through coal bed with piston stream mode, all contact combustion Burning face burning discharges net quantity of heat, air utilization ratio reaches air mass flow and the combustion front burning that 100%, i.e. blower fan are blasted The air mass flow that consumed is equal to be directly proportional.Tight between briquet and briquet, it is natural to affect without combustion-supporting short-circuit of air, it is ensured that wind Performance of control of the machine start-stop to furnace temperature.Obviously, performance of control of the air to combustion heat release, depending on static pressure area closure and operation Channel lumen air trapping amount, operating walk way inner chamber air trapping amount depend on operating walk way right output port sealing.Coal bed top surface On 2 top end face of bosh, gapless between coal briquette hole device to hole and briquet, fire door 4 can fully seal operating walk way right output port, favorably In air regulation process of the maintenance blower fan start-stop to participation combustion reaction.As shown in Figure 3, continuous tunnel furnace static pressure area near enter Mouth end fire door, static pressure area top surface are not closed, and aerator blasts the gas on most of air by-pass to coal bed top surface in static pressure area Phase space simultaneously rapidly flows toward exhaust opening (smoke evacuation is oxygen-containing to be up to 11%～12%), and remainder flows into coal with the bag-shaped mode of jet of cloth The bed inter-air space.The bag-shaped jet of cloth Convention diffusion in the coal bed needs to overcome larger resistance, lime-ash ball to stop that combustion air flow to Combustion front, stop heat smoke float and flow to furnace roof gas-phase space, and unburned coal briquette stops heat smoke flow forward, final to participate in burning Air mass flow it is few, combustion heat release is few, and content of CO in smoke is high, interior quantity of heat storage is more, further reduces combustion heat release, and consolidated statement reveals Furnace temperature rises not get on, and hot blast temperature is less than 2 DEG C～8 DEG C of preset temperature.A little portion in the simply air that stove chamber inner combustion is consumed Point, the air mass flow of blower fan start-stop control is not directly proportional to the air mass flow of combustion front consumption, undoubtedly increases blower fan start-stop certainly The difficulty of the air mass flow process that dynamic regulation and control burning is consumed.Air mass flow and stream that continuous tunnel furnace blower fan is sent into enter the air stream of coal bed Amount is not directly proportional, and stream enters the air mass flow of coal bed and combustion heat release amount is not directly proportional so that blower fan start-stop regulates and controls to hot blast temperature It is poor-performing, unstable unreliable.Up baking quality of tobacco is not affected for reducing furnace temperature and rising, changing yellow stage and fixation stage are operated Work duty sees that fire becomes one of tobacco flue-curing basic administrative task.The normally opened furnace temperature that also do not rise of blower fan that continuous tunnel furnace operation is present is asked Topic, is easily erroneously interpreted as that coal-fired calorific value is low, and the most frequently used measure is to use more high heating value (5500kCal/kg～7000kCal/kg) instead , so easily there is localized hyperthermia in burner hearth and hardening crack furnace roof arch brick in anthracite or bituminous coal, increase tobacco flue-curing fuel cost, discharge The problems such as smoke pollution environment.Utility model furnace roof 1, bosh 2 and operating walk way shell link into an integrated entity for full weld and seamless Metal shell, metal shell thickness 3mm～5mm, to guarantee the sealing of air stove intracavity space, infilters stove without surrounding air Thorax, it is ensured that it is controllable that furnace temperature is adjustable.When furnace sidewall backplate is made with narrow reinforcing bar precoated plate alternative metals housing, furnace wall easily goes out continuous tunnel furnace Existing hightemperature cracks, penetrate into the air mass flow inconvenience control of burner hearth, furnace temperature easily occur out of control or even to 68 DEG C～70 DEG C phenomenons.It is practical Novel metal housing full weld links into an integrated entity formula structure, and the closing of static pressure area, vertical furnace chamber, vertical are banked up briquet and from coal bed top Face center fire such as is ignited at the design so that the air mass flow and stream that blower fan is sent into is entered the air mass flow of coal bed and be directly proportional, and stream enters coal The air mass flow and combustion heat release amount of bed is directly proportional, so as to ensure that good blower fan start-stop to hot blast temperature performance of control, energy Ensure baking quality of tobacco, save changing yellow stage and fixation stage operative employee's duty sees that firer makees.

Caused by " open fire reverse combustion ", the three of technical characteristic are " high temperature isolation ".As shown in Figure 3, on the inside of tunnel furnace door i.e. For high temperature combustion zone, static pressure area and high temperature combustion zone overlap as one, the high temperature combustion zone high temperature furnace when blower fan temporarily ceases air-supply Gas can pass through vent and Ramulus Et folium Spiraeae Acuminatae reversely blows to blower fan, adds blower fan and is acted on by fire door hyperthermia radiation, causes fan casing Temperature is increased to 200 DEG C～250 DEG C, fan static pressure decline occurs, and air mass flow diminishes, or even is directly burned out, combustion fan Become continuous tunnel furnace replacement frequency highest, consume most parts.Calculate within 2 months by baking in a year, number of units is changed at 1～4.For Blower fan renewal cost is reduced, operative employee's duty sees that blower fan becomes one of tobacco flue-curing basic administrative task.Utility model is based on naked light Anti- to burn principle, high-temp combustion face is located proximate to the coal bed top area of furnace roof 1, has certain between high-temp combustion face and static pressure area The coal bed of height is separated by, and adds high-temperature furnace gas and rises naturally flowing so that the quiet nip space being connected with blower fan is in all the time Low temperature state, is detained without high-temperature furnace gas and the appearance of blower fan phenomenon is burnt in refluence, without the diligent monitoring combustion fan operation of operative employee, solution Blower fan high temperature scaling loss and operation insecurity problem that continuous tunnel furnace of having determined is present.

Utility model technical characteristic " open fire reverse combustion " is the precondition of reverse burning furnace energy-conservation, reduction of discharging, safety, autocontrol operation. Utility model technical characteristic " high temperature isolation " is the inevitable outcome of " open fire reverse combustion ".Technical characteristic " it is controllable that furnace temperature is adjustable " is Nicotiana tabacum L. The key guaranteed both quality and quantity is toasted, is the key that utility model is able to popularization and application.

Effective resultant effect that said structure feature and technical characteristic bring is that reverse burning furnace energy-saving environmental protection safety performance is obtained Increase substantially.Utility model is disposably comfortably coaling deashing；Economize on coal, flue gas CO discharges are ultralow, tobacco flue-curing is reduced to combustion Coal high heating value is required；Baking process curve combustion heat supplying can be close to and generate hot blast, without furnace temperature is out of control and furnace temperature rises and do not ask up etc. Topic；Scaling loss combustion fan hidden danger is flow backwards without high-temperature furnace gas.

The Nicotiana tabacum L. Processing farage industry of combustion using honeycomb briquet brick, tobacco planting processing base and tobacco grower cooperative society intensive flue-cured tobacco and Loose-leaf curing combustion heat supplying generates hot air apparatus, hot air chamber and air stove, it is possible to use utility model.

Tobacco flue-curing practice have shown that：Disposably coaling deashing, coaling comfortable, deashing is easy；Igniting is ignited simple；Smoke evacuation temperature Degree<80 DEG C, flue gas CO discharges reduce by 75%, and coal-fired calorific value saves more than 25%；Blower fan start-stop is good to hot blast temperature performance of control It is good, baking process curve can be close to and generate hot blast, be occurred with warm phenomenon is fallen without overtemperature；Leak without high-temperature furnace gas, blower fan temperature begins It is less than 38 DEG C eventually, without high temperature over-heated fault；Saving of work and time cost declining；Dry tobacco leaf quality better, is lost without endoplasm, can use ash and contain Amount up to 50%, the local cellular briquet of calorific value as little as 3000kCal/kg～4000kCal/kg.
