Abstract
The utility model discloses a smoke prevention and dust control combustion apparatus which is suitable for industrial kilns and miniature industrial boilers, and the utility model comprises a driving apparatus, a boiler wall, a coal bucket, a lower feeding type spiral coal feeding machine, a fixed fire grate and a movable fire grate, wherein, the lower feeding type spiral coal feeding machine is positioned on the lower parts of the fixed fire grate and the movable fire grate, a secondary blowing port is arranged on the boiler wall above the fixed fire grate and the movable fire grate, and the lower part of the fixed fire grate is provided with a primary air inlet. The utility model has the advantages of simple structure, convenient manufacture and enforcement, energy saving and low consumption without increasing occupation area and achieves energy-saving and environment-treating double purposes, and the utility model is an ideal apparatus for eliminating smoke and dust for the industrial kiln and the miniature industrial boilers which have fixed fire grates and are manually and discontinuously fed with coal.
Description
The utility model relates to a kind of burner, particularly a kind of smoke abatement and dust control burner that is applicable to fixed grate, hand-stoked Industrial Stoves and miniature boiler.
At present, along with development and national economy, the enhancing of national environmental consciousness, three waste discharge to all trades and professions requires more and more higher, the Industrial Stoves of fixed grate, manual intermittent increase of coal and small-sized industrial boiler discharge volume of smoke in process of production, are difficult to adapt to present environmental requirement as not administering, production can't be carried out, though propose a lot of technical schemes both at home and abroad in recent years, also only be to administer in the back to work hard, and expense is big, power consumption is high, incompatible national conditions at present far away.
The purpose of this utility model just is to overcome outside the deficiency of the prior art, a kind of simple in structure, enforcement convenience is provided, eliminate smoke, good dedusting effect, less energy consumption is applicable to the smoke abatement and dust control burner of fixed grate, hand-stoked Industrial Stoves and miniature boiler.
The purpose of this utility model is to realize like this, it comprises: transmission device, furnace wall, coal bunker, lower feeding screw-type coal distributor, fixed grate, moving grate, the lower feeding screw-type coal distributor is positioned at the bottom of fixed grate, moving grate, coal bunker be contained in lower feeding screw-type coal distributor outside the furnace wall above, the furnace wall of fixed grate, moving grate top is provided with the secondary blast mouth, the bottom of fixed grate is provided with wind inlet one time, the lower feeding screw-type coal distributor of inside, furnace wall is provided with coal outlet, and the bottom of furnace wall is provided with taper laying dust device.
The purpose of this utility model also can realize by following technical measures, under the taper laying dust device cleanout is housed, and is provided with the screening hawk between fixed grate and the lower feeding screw-type coal distributor.
The utlity model has following advantage compared to existing technology
1, simple in structure and all belong to general parts, make implement convenient.
2, volatile matter fully burnt after mechanical coal feeder replaced manual coal supply, and low temperature, anoxycausis thing are eliminated substantially, improved fire box temperature, reduced consuming, and can economize on coal 20%.
3, the investment than the outer smoke abatement and dust control of any stove all reduces.
4, environment purification has avoided noxious material to be discharged into contaminated environment in the atmosphere.
Accompanying drawing and drawing explanation
Fig. 1 is for realizing the utility model structural representation
Fig. 2 is the utility model A-A section structure schematic diagram
Below in conjunction with drawings and Examples in detail the utility model is described in detail, it comprises: transmission device 1, the furnace wall, the furnace wall is by housing 3, heat-insulation layer 4 is formed, coal bunker 2, lower feeding screw-type coal distributor 5, fixed grate 6, moving grate 7, lower feeding screw-type coal distributor 5 is positioned at fixed grate 6, the bottom of moving grate 7, coal bunker 2 be contained in furnace wall 3 outer lower feeding screw-type coal distributors 5 above, fixed grate 6, the furnace wall 3 of moving grate 7 tops, 4 are provided with secondary blast mouth 9, the bottom of fixed grate 6 is provided with wind inlet 13 one time, furnace wall 3, the lower feeding screw-type coal distributor 5 of 4 inside is provided with coal outlet 8, furnace wall 3,4 bottom is provided with taper laying dust device 11, taper laying dust device is equipped with cleanout 12 11 times, is provided with between fixed grate 6 and the lower feeding screw-type coal distributor 5 to hide hawk 10.Working mechanism of the present utility model is, be " just burning " for the Industrial Stoves and the small-sized industrial boiler traditional combustion mode of the manual intermittent increase of coal of fixed grate, and promptly cinder is descending, the coke oxide layer in, raw coal dry distillation layer is last.Its combustion process is, raw coal adds heat absorption in a large number behind the burner hearth, and furnace temperature descends, and stack draught reduces, and low temperature, anoxycausis occur.Its mechanism is to be heated to 350-600C to discharge a large amount of volatile matters after coal adds, and under burner hearth low temperature, anaerobic environment, generates phenyl ring material carbon black, cyclic hydrocarbon material soot and free charcoal through the number of chemical reaction.Above-mentioned substance is formed jet-black, enters atmosphere with flue gas.In the stove fuel 14 in succession fire burns, furnace temperature rises, exhaust gas temperature rises, the stove internal-external temperature difference strengthens, stack draught increases, and it is smooth to ventilate, and the flue gas of discharge blackly turns greyish white to colourless by dense, but coal-based that adds this moment burns, and needs coal again, occurs said process equally again.The utility model adopts lower feeding screw-type coal distributor 5 by coal outlet 8 coal supplies, fire coal is added in the coal bunker 2, tradition " is just burnt " change anti-burning into, be that transmission device 1 drives 5 rotations of lower feeding screw-type coal distributor, make it from burning zone bottom coal supply, just cinder layer in the above, raw coal dry distillation layer is below.Raw coal below the coke burning zone discharges gradually because of its volatile matter of conduction heat that is subjected to the coke burning zone, and enter coke layer 14 with a wind that feeds for 6 times from fixed grate, all burnings, do not exist anoxic, low temperature generation series of chemical to produce the condition of jet-black, therefore accomplished smoke abatement and dust control.Except that having taked backfire not produce black smoke or having produced the secondary wind that also feeds total burning air quantity 10-15% the black smoke by the overfiren air port on the furnace wall less at flue gas aditus laryngis place, make volatile matter residual in the flue gas or flying dust contain further fully burning of charcoal, this method is eliminated black smoke on the one hand, on the other hand the combustible in the flue gas is burnt as far as possible, improve efficiency of combustion, and improved furnace temperature.As for dedusting, because making it become hand-firing, this combustion apparatus belongs to a small amount of, even coal after for the machinery burning, its flue gas flow is longer, and the abundant sedimentation time is arranged, and is equivalent to the inertial dust collection expansion chamber.Therefore can make the sedimentation in stove of most of flue dust, the flue gas of discharge can reach discharge standard.The slag that produces is provided with screening hawk 10 and can prevents effectively that dust from entering the combustion chamber from discharging burner hearth by moving grate 7 hand shaken between fixed grate 6 and the lower feeding screw-type coal distributor 5, cleanout 12 is convenient to burner hearth is cleaned.Reach fully burning in the burner hearth with this way, combustible is eliminated within burner hearth, and low temperature, anoxic produce the condition of noxious material and eliminated, thereby reaches the purpose of smoke abatement and dust control and energy savings.
