The wind chamber is connected with a fan outlet through a secondary blower tube. The utility model can enable combustible smoke and dust generated during burning to burn sufficiently, which can reduce pollution and save coals. The utility model is suitable for personnel dining room cooking ranges and other restaurant industries.
Description
The utility model relates to a kind of coal stove that uses solid fuel, a kind of smoke-eliminating energy-saving furnace that is suitable in staff canteen's kitchen range and the use of other catering industry of more specifically saying so.
In the prior art, staff canteen's kitchen range and coal stove that other catering industry uses structurally mainly contain two kinds: a kind of is blowing-type, mainly form by burner hearth, fire grate and air blast, blow down to fire grate by air blast during use, make the burner hearth internal combustion of coal on fire grate, the kitchen range on its top are heated; Another kind is the exhausting formula, mainly is made up of burner hearth, fire grate and the chimney that is connected with upper furnace, and the dependence chimney draught makes coal in the burner hearth internal combustion during use, and the top kitchen range are heated.The common drawback of these two kinds of coal stoves is to adopt the method burning of direct coal on fire and do not have smoke consuming apparatus, the billowing black smoke of can emerging during use, and both contaminated environment wasted energy again.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of smoke-eliminating energy-saving furnace is provided.
For finishing above-mentioned purpose, technical solution provided by the utility model is: a kind of smoke-eliminating energy-saving furnace, comprise burner hearth 11, be installed in the fire grate 10 of burner hearth 11 bottoms, fire door 6, blower fan 7 and an ajutage 8, its special character is, burner hearth 11 1 sides on described fire grate 10 are provided with a preheating destructive distillation chamber 5, described fire door 6 is installed on the outer end of this preheating destructive distillation chamber 5, on described burner hearth 11, be provided with a dedusting dish 4, be provided with a fire-resistant cover 2 on the dedusting dish 4 and be positioned at smoke eliminator 13 among the fire-resistant cover 2, have fresh air inlet 14 on the sidewall of this smoke eliminator 13, leave air compartment 15 between described fire-resistant cover 2 and the smoke eliminator 13, air compartment 15 links to each other with the air outlet of secondary blast pipe 3, the air inlet of secondary blast pipe 3 links to each other with the air outlet of blower fan 7, and the top of described air compartment 15 is provided with seal disc 1.
Can install a circular vane 12 in the air compartment 15 in the above-mentioned technical solution, have wind pushing hole 23 on it, the air inlet of this circle vane 12 links to each other with the air outlet of secondary blast pipe 3.Can make the secondary air in the air compartment 15 to send in the smoke eliminator by the fresh air inlet 14 on smoke eliminator 13 sidewalls more equably like this.
Can be separately installed with a volume damper 21,22 on ajutage 8 in the above-mentioned technical solution and the secondary blast pipe 3, like this can be according to the situation of burning, adjust the air quantity of first and second air intake when needed respectively, so that make it can reach the combustion efficiency an of the best.
Accompanying drawing has been described a preferred embodiment of the present utility model.
Fig. 1 is the sectional structure schematic diagram of this embodiment.
Fig. 2 is the structural representation of circular vane among this embodiment.
Each label declaration is as follows among the figure:
The 1-seal disc, the fire-resistant cover of 2-, 3-secondary blast pipe, 4-dedusting dish, 5-preheating destructive distillation chamber, 6-fire door, 7-blower fan, ajutage of 8-, the 9-deashing chamber, 10-fire grate, 11-burner hearth, 12-annular vane, the 13-smoke eliminator, 14-fresh air inlet, 15-air compartment, 16-pot seat, the 17-pot, 18-venthole, 19-combustion chamber, 20-sees vent, and 21, the 22-volume damper, the 23-wind pushing hole.
Referring to Fig. 1, Fig. 2, this smoke-eliminating energy-saving furnace has a spherical hearth 11, fire grate 10 is equipped with in burner hearth 11 bottoms, it under the fire grate 10 deashing chamber 9, burner hearth 11 1 sides on fire grate 10 are provided with a preheating destructive distillation chamber 5, fire door 6 is equipped with in the outer end of this preheating destructive distillation chamber 5, the air outlet of an ajutage 8 is positioned under the fire grate 10, air inlet links to each other with the air outlet of blower fan 7, be provided with a dedusting dish 4 on the burner hearth 11, be provided with a fire-resistant cover 2 on the dedusting dish 4 and be positioned at smoke eliminator 13 among this fire-resistant cover 2, the middle part of this smoke eliminator 13 is connected with burner hearth 11 by the circular hole at dedusting dish 4 middle parts, have fresh air inlet 14 on the sidewall of smoke eliminator 13, leave air compartment 15 between described fire-resistant cover 2 and the smoke eliminator 13, be equiped with a circular vane 12 in the air compartment 15 around smoke eliminator 13, have wind pushing hole 23 on the circular vane 12, the air inlet of this circle vane links to each other with the air outlet of secondary blast pipe 3, the air inlet of secondary blast pipe 3 then links to each other with the air outlet of blower fan 7, for guaranteeing the cleaning and the sealing of air compartment 15, be provided with seal disc 1 on the top of air compartment 15, on a described blast pipe 8 and secondary blast pipe 3, a volume damper 21 and 22 be housed respectively.
During use this smoke-eliminating energy-saving furnace is loaded in the bearing 16 of kitchen range pot 17, on bearing 16, reserves an observation door 20 and an outlet flue 18, and between pot and this stove, leave the combustion chamber.This stove adopts just burning method burning of naked light, generally should close blower fan 7 during coal, the new coal that adds from fire door 6 is deposited in earlier in the preheating destructive distillation chamber 5 at every turn, and then close fire door 6, after the naked light preheating of these new coals in burner hearth 11, wherein the fugitive constituent that is comprised will distillate lentamente, by the time again these fire coals through the preheating destructive distillation are pushed into during coal on the naked light in the burner hearth 11 next time and burn, having granule in the partial combustion during burning is blown afloat and is moved upward, the burning once more in the naked light that after the lower surface bounce-back of dedusting dish 4, can fall into once more on the fire grate 10 of part in these granules, partly then can also fall back in the burner hearth once more and burn away because of the influence that secondary air in the smoke eliminator 13 slows down the thermal current flow velocity, after not having the flue dust of completing combustion and various imflammable gas to mix together with the secondary airs in the smoke eliminator 13, burn away in the combustion chamber 19 at an upper portion thereof, to reach the purpose of smoke elimination.Can regulate the size of first and second air output during burning according to different fire coals by volume damper 21 and 22,, flammable flue gas fully be burnt so that stove is in preferable fired state.
In conjunction with the foregoing description as can be known, the utility model has following three advantages compared to existing technology:
1, combustion particle that produces in the time of can be with the stove internal combustion and various imflammable gas carry out the burning second time, significantly reduce the discharge capacity of flue dust, reduce environmental pollution, meet every environmental protection index requirement of national regulation through environmental administration's test;
2, fully burn because of it can make the coal-fired flammable flue dust that produces when burning, thereby can save fire coal greatly, its coal saving rate can reach more than 40% than traditional coal stove;
3, can be suitable for using and various types of cigarette and smokeless coal-burning are arranged, and fume emission all can satisfy environmental requirement.
