Abstract
The utility model discloses a waste heat internal dust-removing hot-air furnace, comprising a chain furnace body, wherein, a swirl dedusting chamber is arranged on one side of the combustion chamber of the chain furnace body; the swirl dedusting chamber is a round cavity; a smoke guiding vent communicated with the combustion chamber is arranged on the upper part of the swirl dedusting chamber along the tangential direction of the round cavity; a dust outlet is arranged on the lower part of the swirl dedusting chamber; a flue gas inlet and a flue gas outlet are respectively arranged on two relative sidewalls of the swirl dedusting chamber positioned in the axial direction of the round cavity. Compared with prior hot-air furnaces, the utility model has the advantages of that: the swirl dedusting chamber is small in volumn and compact in structure; the occupied area of the whole hot-air furnace is decrease by nearly one half than old type hot-air furnaces; and compared with prior hot-air furnaces, the thermal efficiency is increased by about 5%.
Description
Technical field
The utility model relates to the hot-blast stove that is used for providing to crops and food drying industry thermal source, especially relates to the built-in cleaning type hot-blast stove of used heat.
Background technology
At present, domestic production be used for crops and food drying industry, be that the hot-blast stove of fuel mainly contains following type with the coal: 1, the dust-laden high-temperature flue gas that produces more than 1000 ℃ of Combustion of Hot Air Furnace directly mixes with cold air, as crops and food drying industry thermal source use (abbreviation direct-type hot-blast stove); 2, the dust-laden high-temperature flue gas of Combustion of Hot Air Furnace generation more than 1000 ℃ mixes with cold air earlier, reduces temperature, again by heat-exchange apparatus heats cold air, uses (abbreviation indirect type hot-blast stove) as crops and food drying industry thermal source.The dedusting of these two kinds of hot-blast stoves mainly by the expansion chamber of big volume, reduces flue gas flow rate, relies on dust gravity natural subsidence to reduce dust content, reduces the wearing and tearing and the pollution of heat transmission equipment; The dust-laden high-temperature flue gas more than 1000 ℃ that hot-blast stove produces mixes the back cooling by the cold air that sucks some, satisfies the drying equipment requirement.The shortcoming that relies on dust gravity natural subsidence to reduce dust content is that floor space is big, and the heat of the high temperature carbon granules that settles down can not utilize, and also needs artificial ash disposal simultaneously; Reduce flue-gas temperature and take to mix cold air, absorb the heat that hot-blast stove self produces, increase the hot-blast stove Fuel Consumption.
The utility model content
The utility model purpose is to provide a kind of used heat built-in cleaning type hot-blast stove.This hot-blast stove is simple in structure, floor space is few, good dedusting effect and energy consumption are low.
The utility model purpose is achieved through the following technical solutions:
The built-in cleaning type hot-blast stove of described used heat, it comprises the chain body of heater, side in described chain combustion chamber of furnace body is provided with the rotational flow dust-removing chamber, described rotational flow dust-removing chamber is a circular cavity, offer the smoke guide port that communicates with described combustion chamber on top, rotational flow dust-removing chamber along described circular cavity tangential direction, offer ash hole in bottom, rotational flow dust-removing chamber; On relative two side, rotational flow dust-removing chamber, be positioned at the circular cavity axis direction and be respectively arranged with gas approach and exhanst gas outlet.
Described ash hole is for to offer vertically downward along described circular cavity tangential direction.
The utility model is compared the advantage that is had with existing hot-blast stove: rotational flow dust-removing chamber volume is little, compact conformation, and whole hot-blast stove floor space reduces nearly 1/2 than old-fashioned hot-blast stove, and compares with existing hot-blast stove, and the thermal efficiency improves about 5%.The setting of rotational flow dust-removing chamber, make and produce dust-laden high-temperature flue gas more than 1000 ℃ in the combustion chamber, under the suction of air-introduced machine, tangentially enter the rotational flow dust-removing chamber at a high speed through smoke guide port, the dust-laden high-temperature flue gas is done rotation at a high speed around rotational flow dust-removing chamber wall under action of centrifugal force, prolonged the burning time of carbon granules in the dust-laden high-temperature flue gas; Along with the completing combustion of carbon granules, its quality alleviates, and gets rid of from ash hole; High-temperature flue gas after the dedusting enters heat-exchange apparatus from exhanst gas outlet.Flue-gas temperature drops to about 150 ℃ after the heat exchange, enters atmosphere through air-introduced machine; Because heat transmission equipment the upper limit temperature of heat tolerance is less than 900 ℃; in order to protect heat transmission equipment not burnt out and energy savings; the air-introduced machine outlet is drawn the waste heat flue gas of some; enter the rotational flow dust-removing chamber through described gas approach; under the perturbation action of the high-temperature flue gas that rotates at a high speed; useless flue gas about 150 ℃ fully mixes with high-temperature flue gas more than 1000 ℃; the fuel gas that useless flue gas is contained further burns; useless excess air that flue gas contains helps the burning of carbon granules in the high-temperature flue gas, makes it to become 600-900 ℃ of hot flue gas that meets the heat transmission equipment requirement.
