Description

Vertical energy-saving eliminating smoke and dust two-use furnace

The utility model belongs to steam-water dual-purpose stove field.

The many in the past old-fashioned straight barrel type thermal efficiency of heating furnace of the kind of domestic and international existing steam-water dual-purpose stove are relatively lower at present only reaches about 20～30%, though domestic over the past two years development phase transition of vacuum heat-pipe furnace and back fire formula phase-change heat transfer heat pipe, the air heat efficiency of furnace increases but still exists 1. manufacturing process complexity, production cost height, the shortcoming that service life is short.2. various air-supply structures can't satisfy oxygen-enriched air required when burning fully.3. existing dedusting structure more complicated increase cost efficiency of dust collection hangs down and stops up, need often clear up, increase labor strength easily.

The purpose of this utility model is to have developed a kind of new-type vertical energy-saving smoke abatement and dust control steam-water dual-purpose stove at the shortcoming and defect of at present existing steam-water dual-purpose stove.

Advantages such as this stove and accessory has product design advanced person, uniqueness rational in infrastructure, thermal efficiency height, the saving energy, coal is scalable, smoke medicining dust-removing effect is remarkable.

The technical solution of the utility model is achieved in that on the basis of the furnace binding that adopts advanced steam-water dual-purpose stove and an existing air-supply structure and secondary blast structure has increased air-supply structure again uniquely three times.This air-supply structure can rotate parallel cloth wind near hanging courage, form oxygen-enriched air film and unburnt imflammable gas and fully mix, and forms distinctive gas-fired on the top of combustion chamber.Flammable charcoal in the combustion chamber is fully burned produces a large amount of heats.And pass to speed full out and to hang in the courage and the water in the flue all around, thereby improved the thermal efficiency of this stove widely.In hanging courage, also be mounted with the convection current radiant heat transfer pipe of a plurality of elbow shapes.Have high-temperature flue gas to have two by its effect fast in the heat-transfer pipe, 1. with heat of high temperature from hanging in the courage radiation feedwater fast, 2. the flue gas that passes through fast is ejected in the flue gas ring that the exit forms a rotation again from outlet.To hit and get back to three wind regions and make that unburnt imflammable gas burns once more the flue gas from hanging the flue gas that rises around the courage, the graininess dust that is hit back falls to melting down in the thorax.Played the effect of smoke abatement and dust control.Top at body of heater is equipped with heater assembly, and umbrella antiradiation dedusting plate is housed in heater assembly, is got back to burner hearth in further that heating burn the purpose that further reached smoke abatement and dust control thereby the granular flue dust in the flue gas of rising hits again here.

Figure of description is the example structure generalized section of technical solutions of the utility model.

Below in conjunction with the embodiment accompanying drawing the technical solution of the utility model is further described:

Air blast enters secondary air box (12) by secondary air channel (2) by a wind apparatus (1) when blasting furnace bottom and enters airduct (13) then as can be seen from accompanying drawing, and airduct (13) is close on the welding furnace wall, and here cold air is heated.Hot-air at first blows in the burner hearth by secondary tuyere (3).Several secondary tuyeres of this stove are installed on the furnace wall of fire grate (18) top according to the direction of certain angle.The secondary hot-air that blasts in the stove makes interior imflammable gas of stove and flue gas rotation rising cause the chance of imflammable gas second-time burning, makes flue and hang courage to have prolonged heated time.Hot-air in the airduct (13) continues to rise to tertiary air mouth (5) to be located to be obstructed (having arrived airduct (13) end socket place), and all hot blast sprays in the burner hearth by tertiary air nozzle (5) at a high speed.Several tertiary air mouths (5) are according to air motion scientific principle opinion, selected certain angle and direction be placed in furnace wall around, near hanging courage (7) vicinity.The hot blast that sprays in the burner hearth by tertiary air mouth (5) rotates parallel cloth wind near hanging the courage place in stove, the top that the imflammable gas that forms an oxygen-enriched air film and do not burn is blended in the combustion chamber forms distinctive gas-fired, make fully burning under the high temperature of flammable charcoal in stove in the combustion chamber, produce a large amount of heats with prestissimo pass to hang in the courage and flue in water, thereby improved the thermal efficiency of this stove widely.Hang the convection current radiation resistance dirt heating tube (6) that courage (7) inner chamber also is mounted with several elbow shapes, having high-temperature flue gas to have two by its effect fast in this pipe.1. in hanging courage with elevated temperature heat radiation feedwater once more, played the direct-fired effect of water.To get back to the tertiary air district from hanging the flue gas collision of rising around the courage at exit formation one deck rotation flue gas ring when 2. high-temperature flue gas is from outlet (18) ejection fast, the flue gas that does not burn forms coal gas with three hot blasts mixing once more here and burns.Hit back and fallen to melt down in the thorax after grit in the flue gas falls, this pipe has played the thermal efficiency effect that the resistance dirt that eliminates smoke improves stove, a flue gas part that rises by the formed flue gas ring of outlet (18) enters the heater assembly (8) that upper of furnace body is installed by passage (17) another part in the middle of the flue by heating tube (15), here heating tube (15) and passage (17) have improved efficient with the radiation feedwater once more of the waste heat in the flue gas.In heater assembly (8), be mounted with the umbrella dedusting baffle plate (9) that supports with several brace rods (16), blocked by umbrella dedusting baffle plate (9) when entering into the heater flue gas, make flue gas in heater assembly, produce eddy current once more, waste heat is fed water by the heater assembly transmission once more, the dust of the small quantities of particles shape in the flue gas is got back in the burner hearth by retaining, this stove by above several device for eliminating smoke and dust after after tested smoke dust discharge concentration be lower than 94.9/m ³Exhaust gas temperature is lower than 162 ℃ flue gas and discharges by chimney (14) from umbrella dedusting baffle plate (9) and heater assembly center-aisle.

The utility model adopt above structure by long-term examination burn compare with other steam-water dual-purpose stove with the testing result of relevant department have thermal efficiency height, economize on coal, characteristics that automatic smoke medicining dust-removing effect is given prominence to. It is the novel carbonated drink dual-purpose stove that a kind of widely users welcome.
