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.
