Description

New-type hot-blast stove
One, technical field
The utility model relates to a kind of heating equipment, is mainly used in to green house of vegetables heating and fruits and vegetables, medicinal material system to do.
Two, background technology
In northern China winter, it is not enough that green house of vegetables only depends on solar radiation heating, also must heat to green house of vegetables.All need hot blast to make the energy at aspects such as food, agricultural product, medicinal material processing, housing heatings in addition.The most frequently used way is in booth, to build out stove and wall with flues with fragment of brick in the prior art, and coal is put into the stove internal combustion, and the high-temperature flue gas of generation heats wall with flues, and the heat radiation through wall with flues comes heat supply in booth or house.The advantage of this heat-supplying mode is a small investment, and technology is simple.But because fragment of brick is thicker, and the thermal conductivity of brick is extremely low, therefore the very low principle that does not meet energy-saving and emission-reduction of this heating method thermal efficiency.A kind of hot-blast stove has also appearred in recent years; Its principle is that the coal-fired high-temperature flue gas that produces of burner hearth is passed the tubulation that is arranged in the heat exchange box, discharges from chimney then, is blown into cold wind with air blast to heat exchange box simultaneously; Carry out becoming hot blast after the heat exchange with the tubulation outer wall, discharge from the air outlet of heat exchange box.This hot-blast stove has improved the thermal efficiency than the former, but because its burns is lump coal, lump coal is expensive, and cost is high; The flyash that produces after the lump coal burning in addition is very light, elegant with the wind everywhere, contaminated environment; Also have because lump coal burns soon, need stoking, cleaning slag in stove continually, take a lot of trouble effort.
Three, technical scheme
In order to overcome the above-mentioned shortcoming of prior art, the purpose of the utility model provides a kind of environmental protection and energy saving, low cost, the labour-saving heating equipment of saving worry.
For achieving the above object, the technical scheme of the utility model is: new-type hot-blast stove comprises a preheating furnace
With a holding furnace.Preheating furnace mainly is made up of body of heater, burner hearth, fire grate, fire door, ash hole, preheating furnace
The below be fire grate, fire grate top is a burner hearth, is distributed with the smoke pipe that leads to flue around the burner hearth, and fire door, ash hole are arranged on side wall of furnace; It also comprises a holding furnace; Holding furnace has an interior horizontal direction of body of heater, body of heater that is connected as a single entity with preheating furnace to be welded with upper spacer and lower clapboard, and 2-20 pipe shape burner hearth arranged, and it is welded on respectively in the hole prefabricated on upper spacer and the lower clapboard at two ends up and down; At each pipe shape burner hearth bottom; A circular fire grate is arranged, around pipe shape burner hearth, be distributed with smoke pipe, their two ends up and down are welded on respectively in the hole prefabricated on upper spacer and the lower clapboard; At the body of heater top chimney, bell and air outlet are arranged; Air inlet is arranged on sidewall of the furnace body, between each pipe shape burner hearth, have ignitron to interlink successively, wherein have the burner hearth of ignitron and preheating furnace to interlink from a nearest pipe shape burner hearth of preheating furnace.
Adopted technique scheme; Because new-type hot-blast stove is made up of preheating furnace and holding furnace two parts; And the preheating furnace burner hearth is big, caloric value is many, when new-type hot-blast stove is started working, lights preheating furnace earlier, when temperature reaches desired value in the hot house; The stoppage in transit preheating furnace, at this moment the high-temperature flue gas in the preheating furnace is lighted a pipe shape burner hearth that leaves recently in the holding furnace through ignitron.Holding furnace is made fuel with honeycomb briquette; When the honeycomb briquette after-flame in the pipe shape burner hearth, the high-temperature flue gas that is produced is lighted the honeycomb briquette in the next pipe shape burner hearth through ignitron, by that analogy; Honeycomb briquette all burnt in whole pipe shape burner hearths; Open the bell that is positioned at the body of heater top again, take out slag, add honeycomb briquette.Because honeycomb briquette has added clay as binding agent when making, the slag that take out its burning back still keeps original body, can not produce ashes and fly upward, so it helps environmental protection; Owing to,, just reduced the discharging of carbon so its consumption coal is few along with hot house gets into holding stage and uses the less pipe shape burner hearth of volume accordingly; Compare with radiator with purchase, installation boiler, its disposable less investment is added and is burnt honeycomb briquette than burning the lump coal considerably cheaper, so its cost is low; Owing to light a last pipe shape burner hearth after-flame from first pipe shape burner hearth of holding furnace, add primary fuel and can work between 13-30 hour, so it has alleviated labour intensity, it is laborsaving to save worry.
Four, description of drawings
Fig. 1 is the front view of new-type hot-blast stove, adopts full section;
Fig. 2 is the vertical view of new-type hot-blast stove;
Fig. 3 is the right view of new-type hot-blast stove;
Fig. 4 is the profile of Fig. 1 along the A-A direction;
Five, the specific embodiment.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done explanation further.In Fig. 1 to Fig. 4, new-type hot-blast stove comprises a preheating furnace and a holding furnace.Preheating furnace is a common hot-blast stove in the prior art; Mainly form by body of heater 1, burner hearth 12, fire grate 11, fire door 8, ash hole 17; The below of preheating furnace is a fire grate 11; Fire grate 11 tops are burner hearths 12, are distributed with the smoke pipe 3 that leads to flue 16 around the burner hearth 12, and fire door 8, ash hole 17 are arranged on side wall of furnace.Holding furnace has body of heater 1, body of heater 1 an interior horizontal direction that is connected as a single entity with preheating furnace to be welded with upper spacer 4 and lower clapboard 5.2-20 pipe shape burner hearth 2 arranged, and it is welded on respectively in the hole prefabricated on upper spacer 4 and the lower clapboard 5 at two ends up and down.In the bottom of each pipe shape burner hearth 2, a circular fire grate 6 is arranged.Around pipe shape burner hearth 2, be distributed with smoke pipe 3; Their two ends up and down are welded on respectively in the hole prefabricated on upper spacer 4 and the lower clapboard 5; Chimney 9, bell 14 and air outlet 7 are arranged at body of heater 1 top, on body of heater 1 sidewall, air inlet 13 is arranged; Between each pipe shape burner hearth 2, there is ignitron 10 to interlink successively, wherein has the burner hearth 12 of ignitron 10 and preheating furnace to interlink from a nearest pipe shape burner hearth 2 of preheating furnace.In body of heater 1 lower end two vertical dividing plates 15 are arranged, forming flue 16. preheating furnaces and holding furnace between it and the body of heater 1, to light the high-temperature flue gas that after-combustion produces downward through smoke pipe 3, gets into the flue 16 of both sides, body of heater 1 lower end, more upwards from chimney 9 discharges.High-temperature flue gas is walked out a S shape path in vertical plane, shown in Fig. 1 arrow.The cold wind that air blast is blown into from air inlet 13 in the space between upper spacer 4 and lower clapboard 5, flows through from the slit of smoke pipe 3 and pipe shape burner hearth 2, carries out heat exchange at this, becomes hot blast and sees off from air outlet 7.The cold wind that is blown into is walked out a S shape path, shown in Fig. 4 arrow in horizontal plane.This pair of S path prolonged the distance and the time of heat exchange, improved the thermal efficiency.
