Description
Technical field
The invention belongs to technical field of burner, be specifically related to the new and effective coal powder burner that a kind of road building business is used.
Background technology
At present, China has multiple at the burner that road building business is used substantially, comparatively just general with combustion gas (natural gas) burner, oil burner and coal burner, gas burner is by the restriction of local resources, cannot apply in the place without natural gas, day by day soaring along with fuel price, coal burner is more popular with users with the use cost that its buying is convenient, cheap.On market, existing coal powder burner is made up of coal pulverizer, conveying coal pipe, burner, oil-firing system and a few part of control system.Ignite before this burner operation, need artificial torch to be lighted by fuel oil, oil pilot coal dust, because the ature of coal difference of China various places is comparatively large, with manual firing, ignition success rate is lower, danger is higher simultaneously, and often occurs needing repeatedly to light a torch, and operates extremely inconvenient.And easily cause localized burn in existing coal burner use procedure, the burner hearth life-span is short, burns insufficient, and flame partially fire is serious, and scarfing cinder difficulty, slagging scorification is serious.For solving the problem of local slagging scorification scaling loss, burner hearth adopts the mode rotated to avoid the long-time heat damage in local, but the basic reasons of its slagging scorification scaling loss is ventilation to be arranged unreasonable, coal dust firing is insufficient, flame occurs what skew caused, only changes the problem that the mode rotating burner hearth fundamentally can not solve slagging scorification scaling loss.
Summary of the invention
For solving the above-mentioned defect that prior art exists, the object of the present invention is to provide a kind of compact conformation, coal dust firing is abundant, and ature of coal adaptability is good, long service life, igniting new and effective coal powder burner easily.
For achieving the above object, the technical solution used in the present invention: this new and effective coal powder burner, there is underframe, burner hearth, stable burning room, wind powder governor motion, blower fan, igniter and electric control system, burner hearth is placed on underframe, stable burning room's part embeds in hearth body, stable burning room connects wind powder governor motion and igniter, it is characterized in that: described wind powder governor motion is inwardly provided with outer direct current air channel successively from skin, Whirl deposite tank passage, interior direct current air channel, coal dust air channel and central tube, blower fan and above-mentioned outer direct current air channel, Whirl deposite tank passage is connected with interior direct current air channel, the port of export in described outer direct current air channel is provided with the direct current blade of long distance, the wide-angle swirl vane making wind rotate blowout is provided with in described swirl air duct, the exit position in described interior direct current air channel is evenly provided with multiple direct current blade, described central tube is taper in exit position, described coal dust ducting outlet evenly arranges multiple camber blades, the inner edge of described camber blades and the taper of central tube end coincide, described central tube is positioned at the center in coal dust air channel, and pass coal dust air channel, can move radially in coal dust air channel.
The port of export in described coal dust air channel has the air outlet of taper contraction section, straight length and toroidal.
Described stable burning room, wind powder governor motion and blower fan are fixed on moving frame, and the bottom of moving frame is provided with road wheel, and road wheel is placed in the track on underframe, and driving mechanism ground-engaging wheel moves forward and backward.
Described burner hearth is provided with rotating driving device, and described rotating driving device has two rolling rings be positioned on hearth housing and the idler pulley supporting rolling ring, and each rolling ring is supported by two idler pulleies, and driving mechanism drives idler pulley to rotate.
Adopt the beneficial effect of technique scheme: the port of export in the outer direct current air channel of this new and effective coal powder burner is provided with the direct current blade of long distance, powerful direct current wind is formed at inboard wall of burner hearth, the diffusion of flame can be retrained, reduce the temperature of inboard wall of burner hearth, avoid flame scaling loss inboard wall of burner hearth, the slag blowout burner hearth that can will produce in burner hearth, avoids slag to be bonded on inboard wall of burner hearth, extends the service life of burner hearth.Be provided with the wide-angle swirl vane making wind rotate blowout in described swirl air duct, in the wind of High Rotation Speed, be formed centrally coal dust
burningrecirculating zone, regulates the air quantity in outer direct current air channel, interior direct current air channel and coal dust air channel simultaneously, can expand or reduce diameter and the length of recirculating zone, adapt to wave from low the multiple ature of coal assigning to high volatile according to the quality of ature of coal.When burning high-volatile bituminous coal, increase the wind speed in outer direct current air channel, to compress the length of recirculating zone, suitable reduction swirl air duct air quantity, direct current air channel flow in strengthening, makes flame reach best steady combustion state and makes second-time burning more abundant, and maintaining the best length of flame; When use low wave point bituminous coal or anthracite time, reduce outer direct current air channel volume, to expand diameter and the length of recirculating zone, increase swirl air duct air quantity, direct current air channel volume in reducing, make the steady combustion state that flame reaches best, burning is more abundant, and keeps the best length of flame.Described coal dust ducting outlet evenly arranges multiple camber blades, and coal dust wind rotates and coal dust can fully be mixed with air, and central tube can move radially in coal dust air channel, according to the quality of ature of coal, regulate central tube and camber blades fit clearance, also can regulate the length of flame, igniting is convenient.Stable burning room bottom is provided with walking mechanism, according to the length of flame during coal dust firing, stable burning room can be regulated to stretch into the length of burner hearth, be equivalent to the combustion space adding burner hearth, make burning more abundant, thus decrease the formation of slag, and slag is light and soft shape, powerful outer direct current wind directly by slag ash blowout burner hearth, can not form the phenomenon of slag bonding burner hearth, even if there is a small amount of slag, cleaning also facilitates.The port of export in described coal dust air channel has the air outlet of taper contraction section, straight length and toroidal, has similar Venturi tube structure, coal dust is mixed with air evenly, be beneficial to Thorough combustion.Therefore compared with prior art, there is compact conformation, coal dust firing is abundant, and ature of coal adaptability is good, long service life, feature easily of lighting a fire, and can meet the various heating requirements in road building business.
