Description
Technical field
The present invention relates to a kind of drying equipment, especially a kind of energy consumption is low, bamboo and wood products's drying shed special hot air stove that temperature rise is fast.
Background technology
At present, although the known hot-blast stove kind supporting with bamboo and wood products drying shed is a lot, with regard to the direct combustion hotblast stove of supporting drying shed, its typical version has two kinds, a kind of hot-blast stove is rolled into steel plate the long cylinder of circular segment that a central angle equals greatly 180 o, combustion chamber is set in the front portion of this long cylinder, an ash bucket is established in the below of combustion chamber, flat grate grate is provided with between ash bucket and combustion chamber, the rear portion of the long cylinder of circular segment is high-temperature flue gas delivery line, the rear end of this pipe connects with a simple tubulation radiator, this radiator is by two, or the steel pipe formation that four maximum six roots of sensation are thick, a chimney is established in one end of the top of tubulation radiator.The heat smoke of burner hearth flows through flue gas delivery line, tubulation radiator and chimney in-line arrangement to air; The high-temperature flue gas delivery line of the direct combustion hotblast stove of another kind of supporting drying shed is substantially identical with aforementioned with heat sink part, changes trapezoidal fire grate into unlike by flat grate grate.The defect of the direct combustion hotblast stove of above-mentioned supporting drying shed is, hot-blast stove tubulation fansink designs is simple and crude, the caliber of its radiating tube is thick, radiating efficiency is low, the space occupied is large, add the windage of hot air circulation, heat up slow, energy consumption is high, the high-temperature flue gas delivery line be connected with burner hearth, be in the below of tubulation radiator, not only away from ventilating fan, and due to the obstruct of the tubulation radiator that is subject to thick caliber, the air causing low power ventilating fan to input is difficult to dispel the heat to high-temperature flue gas delivery line, cause it because of overheated and scaling loss, highly shortened the service life of hot-blast stove.
Summary of the invention
Heat up slow to overcome existing bamboo and wood products drying shed hot-blast stove, energy consumption is high, the defect that service life is short, the invention provides a kind of drying shed hot-blast stove, and this hot-blast stove energy consumption is low, and temperature rise is fast, long service life.
The technical solution adopted for the present invention to solve the technical problems is: drying shed special hot air stove is made up of combustion chamber and finned tube exchanger, it is characterized in that the top of combustion chamber, it is the arch furnace roof rolled with steel plate, left plate, right plate that arch cooktop edge connects, header board, rear plate and the network of fire form combustion chamber, are ash bin between the network of fire and base plate; Inner side near left plate, right plate, header board, rear plate builds refractory brick furnace lining by laying bricks or stones, between ash bin and combustion chamber, is provided with secondary air channel, so that air is after cleaning door enters ash bin, portion of air will enter above combustion chamber through secondary air channel; The header board of combustion chamber is provided with fire door, cleaning door, and the top of rear plate is crater tube sheet, connects finned tube exchanger; Finned tube exchanger is one group by many small-bore finned tubes, by the small-bore finned tube of at least three groups, upper, middle and lower-ranking is arranged in through connecting box, connect through successively, form a high-temperature flue gas circulation flow path, form two ports, upper port is connected with crater tube sheet, and lower port is connected with collection smoke box, and chimney is drawn below in the middle part of collection smoke box, under the guiding of air-introduced machine, high-temperature flue gas stream in burner hearth, from top to bottom successively through upper, middle and lower-ranking finned tube exchanger, after arriving collection smoke box, discharge from chimney, form the circulation of high-temperature flue gas stream downdraf; Above finned tube exchanger and arch furnace roof, establish strong blast volume axial-flow fan, make the high-temperature part of this drying shed hot-blast stove all be in the region of air quantity, blast maximum, make finned tube exchanger and arch furnace roof rapid heat dissipation, avoid high temperature scaling loss; Left plate, right plate, header board, rear plate are all rolled into the arc bulged, and the inner side of plate is provided with reinforcement, to damage refractory brick furnace lining in combustion chamber to prevent it because of the impact of being expanded with heat and contract with cold.
The invention has the beneficial effects as follows, thermal effect is high, energy consumption is low, temperature rise is fast, owing to have employed the circulation of high-temperature flue gas stream downdraf, make the high-temperature part of this drying shed special hot air stove all be in the air quantity of axial flow blower, the region of blast maximum, effectively prevent high-temperature part, overheated scaling loss, extends long service life.
