Abstract
The utility model discloses a water fast-charging smoke-tube boiler with flyash spiral-flow reburning device, comprising a boiler chamber comprising a boiler barrel, a boiler grate device, a front arch and a rear arch, a double-return flue, etc., wherein, the front part of the boiler is provided with a flyash separating spiral-flow chamber communicated with the flue, and the inner of the spiral-flow chamber is provided with a spiral-flow barrel of which inner has no smoke flowing; the two ends of the spiral-flow barrel are supported on the boiler walls of the two sides of the spiral-flow chamber; the bottom of the spiral-flow chamber is provided with an ash outlet facing towards the boiler chamber and a secondary air ash blowing device. The utility model has the advantages of reasonable structure, little pollution, high thermal efficiency, and the good effect of flyash processing.
Description
The utility model relates to a kind of flying dust eddy flow feeded water rapidly multitubular boiler of burning device again that is provided with, and it mainly comprises drum, fire grate device, be that bearing support and mounting thereon by the face arch of quarl, burner hearth that rear arch is formed and two backhaul flues etc. is formed by some water pipes.
At present, the domestic fast-assembling Industrial Boiler that generally uses, fire grate are one-sided or the logical logical sequence air-supply of bilateral, and its shortcoming is the air-supply lack of homogeneity, is easy to form burning crater, causes boiler combustion efficiency low; After forming burning crater, a large amount of flying dusts is taken out of boiler row to atmosphere by flue gas, and environmental pollution is very serious.
The purpose of this utility model is exactly a kind of flying dust eddy flow feeded water rapidly multitubular boiler of burning device again that is provided with that designs at existing problem in the above-mentioned prior art, this boiler structure is reasonable, the flying dust treatment effect is good, has reduced environmental pollution, has improved operating thermal efficiency.
The purpose of this utility model realizes by following measure:
Of the present utility model be provided with the flying dust eddy flow again the feeded water rapidly multitubular boiler of burning device mainly comprise drum, fire grate device, by some water pipes is bearing support and the face arch that mounts quarl thereon, compositions such as the burner hearth that rear arch is formed and two backhaul flues, wherein, be provided with the flying dust spin chamber that communicates with flue in the boiler front portion, be provided with the whirl cylinder of inner smokeless air communication in the spin chamber, the two end supports of whirl cylinder is on the furnace wall of both sides, spin chamber, offer an ash hole that leads to burner hearth in the bottom of spin chamber, and be provided with secondary wind apparatus for ash at the ash hole place.
In the utility model, the level inclination of rear arch is preferably 7 °～20 ° (middle high, both sides are low); The ash hole that is arranged on the bottom, spin chamber is L shaped structure; The exhaust duct of secondary wind apparatus for ash for being drawn by the air delivery duct is installed in L shaped ash hole place; Along the fire grate total length deep bead is installed at fire grate two side lower parts.
The utility model compared with prior art has following advantage: owing to be provided with the flying dust cyclone separation device, the flying dust that boiler combustion produces, through behind the flying dust cyclone separation device, a large amount of unburneds are flying dust completely, separated get off and fall on the fire grate burn once more, burning once more along with flying dust, its phosphorus content descends, and weight saving is more easily taken away by flue gas, not only reduce atmosphere pollution, also improved the operating thermal efficiency of boiler.Because forward and backward arch, backhaul flue and the eddy flow flying dust separator of boiler support by boiler water tube, and be both safe and reliable, improved the boiler heat transfer intensity again.The utility model also is equipped with deep bead at fire grate two side lower parts along the fire grate total length, has avoided the air burner hearth that bleeds in a large number from the fire grate both sides, and has saved the cast iron side seal structure of existing fire grate.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model front view
Fig. 2 is the utility model side view
The utility model is done with detailed description below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2: originally be provided with the flying dust eddy flow again the feeded water rapidly multitubular boiler of burning device mainly comprise drum (15), fire grate device (2), form by some water pipes are bearing support and the face arch (4) that mounts quarl thereon, rear arch (5) is formed burner hearth (3) and two backhaul flues etc., the level inclination of rear arch is preferably 7 °～20 ° (middle high, both sides are low); Be provided with the flying dust separating spiral-flow chamber (8) that communicates with flue (7) in the boiler front portion, the whirl cylinder (10) that inner no flue gas passes through is arranged in the spin chamber, the two end supports of whirl cylinder is on the furnace wall of both sides, spin chamber, offer one communicates with burner hearth (3) in the bottom of spin chamber, it is shaped as the ash hole (9) of L, and at the ash hole place one row's blower (11) of being drawn by the air delivery duct is installed; Along the fire grate total length deep bead (14) is installed at fire grate (2) two side lower parts, this fire grate can save the standing cast iron side seal structure of existing fire grate.
The course of work of the present utility model is: bunker coal enters boiler from coal bunker (1), bring the burner hearth (3) of high-temp combustion into by continuous band fire grate (2), red-hot ash-laden gas is by face arch (4), burner hearth (3) water conservancy diversion that rear arch (5) forms is to the first backhaul flue (6) that is formed by boiler drum bottom and upper hose, be folded to and be symmetrically distributed in the drum both sides, the second backhaul flue (7) that forms by upper hose and drum side-lower, ash-laden gas diminishes in the cross section in the second backhaul flue, flue gas flow rate increases, enter spin chamber (8) by both sides, under the effect of whirl cylinder (10), ash-laden gas rotates at a high speed, separated under action of centrifugal force, grit is blown into burner hearth along with being arranged on the blower that L shaped ash hole (11) locates, and falls further burning on the fire grate.Cleaner flue gas then imports front smoke box (12) by spin chamber (8) tangential outlet, and smoke box after drum pyrotechnics pipe (13) enters is discharged boiler at last again.
