Specific implementation mode

The technical solution of this patent is described in more detail With reference to embodiment.

Please refer to Fig.1-3, a kind of efficient cyclone environment-protection boiler, including Whirlwind barrel 1, drum 2 and broken coal case 3, the rotation Air duct body 1 is made of the cylindrical portion 4 on top and the conus portion 5 of lower part, and Whirlwind barrel offers ash hole 6 at 1 lower end center, rotation 1 lower end of air duct body is also fixedly connected with stabilizer blade 7;2 upper end of the drum is fixedly connected on Whirlwind barrel 1 by fixed ring seat 24 Interior, drum 2 is coated with rock wool or shoe plate, and heat is avoided excessively to scatter and disappear, and 2 upper end of drum, which is communicated with, draws outside Whirlwind barrel 1 Filler pipe 8 and return pipe 9,2 lower end of drum are communicated with the outlet pipe 10 drawn outside Whirlwind barrel 1, and drum is fixed at 2 bottom plate center It is connected with combustion tube 11, also fixes the smoke-fire-tube 12 for being communicated with several groups coiled pipe structure on combustion tube 11, smoke-fire-tube 12 passes through It wears drum 2 to draw from its side wall, 11 lower end of combustion tube is connect with ajutage 13, and 13 right end of ajutage draws Whirlwind barrel 1, air-supply 13 lower end of pipe is also fixedly connected with backwind tube 14 at 11 center of corresponding combustion tube, and 14 upper end of backwind tube passes through combustion tube 11, pot Cylinder 2 and Whirlwind barrel 1 are drawn, and backwind tube 14 is being divided into 15 structure of helix tube, 14 lower end of backwind tube and fixation inside drum 2 The blower cover 16 for being connected to 13 lower end of ajutage is connected to;The broken coal case 3 is fixedly connected on 1 right side wall of Whirlwind barrel, broken coal case 3 Upper end is fixedly connected with coal scuttle 17, and baiting valve 18,18 lower end of baiting valve and ajutage are fixedly connected at 3 lower ending opening of broken coal case 13 are connected to, milling roller 19 there are two rotation connections in broken coal case 3, are in close contact between milling roller 19, turn of two milling rollers 19 It is fixedly connected with intermeshing transmission gear on axis, the shaft of one of milling roller 19 and to be fixedly connected on broken coal case 3 right The driving motor 20 of side wall is sequentially connected, and can carry out coal cinder crushing by the rolling effect between two milling rollers 19, in broken coal case 3 Two side is also fixedly connected with the scraper plate 21 being in close contact with two milling rollers 19, and 3 top plate lower end of broken coal case is in corresponding two stone rollers 19 midline of pressure roller is also fixedly connected there are two baffle 25, the coal charge being adhered on milling roller 19 is struck off, 13 right end of ajutage It is connect with the air outlet pipeline of air blower 22, fuel point firearm is also fixedly embedded at by blower cover 16 on the left of 13 lower end of ajutage 23, igniter head of fuel point firearm 23 stretches into ajutage 13, and the oil inlet of fuel point firearm 23 draws from 1 right side of Whirlwind barrel Going out, the structure of above-mentioned ajutage 13 and fuel point firearm 23 is exactly currently used burner structure in fact, but by burner Circulation duct lengthen and move to left 23 position of fuel point firearm, such coal dust is directly blown into combustion tube 11 after lighting and does not exist The circulation excessive time, alleviates heat loss, improves energy utilization rate, in use, coal cinder is put into broken coal in ajutage 13 Dusting processing is carried out in case 3, and coal dust blanking is realized by baiting valve 18, while starting air blower 22 and fuel point firearm 23, Coal dust is blown into inside and lighted a fire via fuel point firearm 23 by air blower 22, as described above, this structural principle with it is common now Burner is identical, and in order to avoid coal dust is tempered, 22 wind speed of air blower need to be more than the rate of fire travel, if boiler power is larger When, roots blower can be used to ensure its wind speed in air blower 22, avoids being tempered, and air blower 22 is also coal dust in addition to providing thrust Burning provide sufficient oxygen supply, in addition, the setting of broken coal case 3 only for facilitating description concrete principle, can also be got rid of It abandons and feeding is carried out using common Coal-disintegrating machine now;It is reached inside combustion tube 11 and smoke-fire-tube 12 rapidly after coal dust ignites It burns, the heat for generation of burning is dispersed into rapidly surrounding and is all absorbed by the cold water in drum 2, the coal dust slag after burning It is discharged by smoke-fire-tube 12 with flue gas, because coal dust firing speed is efficient soon, in combustion tube 11 and smoke-fire-tube 12 when circulation It is enough to burn totally, therefore does not will produce the case where the causing energy waste that jet out flames, boiler ratio is happened at because of burning more now Inside drum 2, heat is fully absorbed, and effectively improves the efficiency of heating surface and energy utilization rate of boiler, 12 both ends of smoke-fire-tube Opening tilts downward, and interior end opening facilitates coal dust and enters smoke-fire-tube 12 diagonally downward, and outer end opening is diagonally downward So that flue gas ejection back pressure is downward, Whirlwind barrel 1 is common cyclone duster structure, and principle is also the same as cyclone dust collectors phase Together, the coal dust slag in flue gas is moved to outer wall under the action of the centrifugal force, reaches wall surface, and in flue gas stream and gravity lower edge Wall falls into ash hole 6, and flue gas is then discharged by backwind tube 14, to achieve the purpose that detach dedusting, to guarantee to be formed rotation Wind eddies stream should be equipped with acute angle as shown in Fig. 2 between 12 outer end of smoke-fire-tube and Whirlwind barrel 1, and its included angle is got over It is small better, optimal effectiveness can be obtained when 12 flue gas of smoke-fire-tube can be blown out from the tangential direction of Whirlwind barrel 1, flue gas passes through return air In 14 discharge process of pipe, UTILIZATION OF VESIDUAL HEAT IN can be carried out by helix tube 15(Though being mark in attached drawing, the outlet of backwind tube 14 can connecting tube Road, which is led to, promotes utilization rate of waste heat in ajutage 13 and broken coal case 3), backwind tube 14 is because being mostly in combustion tube 11, to keep away Exempt from it and absorb waste amount of heat, backwind tube 14 is located at the part within combustion tube 11, and it is heat-insulated often that boiler now can be used in material Alumina silicate makes, and mitigates thermal loss, boiler and deduster are integrated, not only easier for installation, and significantly The floor space of boiler operatiopn equipment is reduced, it is economical and practical.

The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party Formula, one skilled in the relevant art within the scope of knowledge, can also be under the premise of not departing from this patent objective It makes a variety of changes.
