Abstract

The utility model discloses a normal pressure internal smoke abating dust-removing heat synergic boiler. The utility model is characterized in that the top of a combustion chamber (3) of the boiler is a convexity top board (8) whose surrounding is provided with fire sucking tubes (9), (10) of different lengths. The fire sucking tubes communicated with the upper part of a dedusting chamber (4) are used as a passageway of the smoke dust. The dedusting chamber (4) is provided with an arch pointed dust cover (6). The lateral face of a chimney (15) is provided with a flue gas recovery pipe (13), and the smoke dust, as the secondary air, goes into the combustion chamber (3) through a blower and a draught fan. The fire sucking tubes (9) (10), the flue gas recovery pipe (13), a water tube (12), the dedusting chamber (4), and the combustion chamber (3) are all in the water tank of the furnace chamber where the smoke dust and water carry out heat exchange. Thus, the inner part of the boiler forms all around supplemental firing site and condition. As a result, coals are burned sufficiently, and traditional external smoke abatement and dust removal is converted into internal smoke abatement and dust removal. The utility model has the advantages of simplifying equipment, increasing heat efficiency, and eliminating the environmental pollution of smoke and dust.

Description

The hot synergy boiler of interior smoke abatement and dust control

The present invention relates to a kind of interior hot synergy boiler of smoke abatement and dust control.

The normal-pressure hot-water boiler of Xiao Shouing does not generally have smoke abatement device and flue gas recovery tube in the market, so its shortcoming is that the heat energy utilization rate is low, the general 100kg of burning boiling water needs the 3-4kg coal, even up to 5-6kg, dust concentration is big, is generally 3 degree (lingemann blackness).So not only waste the energy but also polluted environment.The normal-pressure hot-water boiler that has, though at chimney outlet cleaner is arranged, the equipment heaviness, floor space is big, costs an arm and a leg, and materials such as the coal grain under removing, dirt ash can not finely be recycled, and caused secondary pollution again, thereby result of use are undesirable.

The purpose of this invention is to provide a kind of normal-pressure hot-water boiler.Except that the 26S Proteasome Structure and Function that keeps general hot-water boiler, its inside is transformed, dust smoke and extraction system and flue gas recovery tube in being provided with, making most of pollutant (combustible) and flue gas (fuel gas) send into the combustion chamber more repeatedly burns repeatedly, strengthened the burning condition of boiler, improved the heat energy utilization rate, make every boiled 600kg water (from room temperature to 95 ℃) only need colm 5kg, with the time be 15 minutes, the thermal efficiency reaches 80% (the national standard thermal efficiency is 73%) after tested, the dust concentration of being discharged is 1 degree (lingemann blackness), has eliminated the pollution of flue dust to environment.

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is the front elevation of the hot synergy boiler of smoke abatement and dust control in the present invention.

Fig. 2 is the profile of the hot synergy boiler of smoke abatement and dust control in the present invention.

The hot synergy boiler of interior smoke abatement and dust control mainly is made up of body of heater 1 air chamber, 2 combustion chamber 3 dirt pockets, 4 burner hearth water tanks 5 and chimney 15.Its design feature is: the top of boiler furnace 3 is a protruding garden shape top board 8, five short fire tube 9 and four apneusis fire tubes 10 inhaled are arranged at an upper portion thereof, from omiting to intermediate, inclined down, the short fire tube 9 of inhaling joins with dirt pocket 4 bottom steel plates, 10 of apneusis fire tubes extend in the dirt pocket 4, there are arch dust excluding hood 6 inside that water pipe 12 is arranged in the dirt pocket 4 as flue, in chimney 15 sides one flue gas recovery tube 13 is arranged, when in the combustion chamber 3 during material combusting, because top board is a protruding garden shape, make burning obtain more fully burning, then flue dust is promptly from inhaling fire tube 9,10 enter in the arch dust excluding hood 6 of dirt pocket 4, not clean-burning weight carbon granules etc. return combustion chamber 3 after being rebuffed, and lighter flue gas enters dirt pocket 4 from arch dust excluding hood 6 bottoms, a part continues to rise to dust excluding hood 6 tops, fall again at this than weight, because the dust excluding hood top can't stop for the pinnacle, automatically fall into dirt pocket 4 again and return combustion chamber 3 burnings through inhaling fire tube, and another part flue gas from the side flue gas recovery tube 13 of chimney 15 through drum, air-introduced machine is delivered to the blast connection 24 of air chamber 2 and fire grate 7 tops and is sent into combustion chamber 3 overheavy firing effects as secondary wind.

All in the burner hearth water tank, here after heat exchange, water is heated by flue dust the water pipe 12 of inhaling fire tube 9,10 flue gas recovery tubes, 13 vacuum tubes 11 in addition and being used for cooling off flue dust, and discharging or reclaim had again improved the heat energy utilization rate after flue dust was cooled.

By above-mentioned transformation to the normal-pressure hot-water boiler internal structure, most of dust pollution thing (combustible) and flue gas (combustible gas) are reclaimed through dirt pocket and flue gas all to be sent back to the combustion chamber and to carry out four overheavy firings, in the dirt pocket fume afterheat again with water pipe in water carried out sufficient heat exchange, improved the heat energy utilization rate, and eliminated the pollution of flue dust environment.

The architectural feature of foregoing invention can be promoted the use of on all thermal boilers.
