Description
The utility model relates to a kind of boiler, relates in particular to the coal-fired smoke-removing boiler of strengthening of a kind of vertical whirlwind, can be used for the industry and people industry.
Present domestic middle and small burn coal boiler is of a great variety, and still, these coal-burning boiler ubiquities the manufacturing process complexity, the production cost height, service life is short, and combustion system falls behind, and it is slow to heat up, and the thermal efficiency is low, it is more limited by coal, region, and smoke medicining dust-removing effect is poor, the ash and slag disposal trouble.
The purpose of this utility model just is to provide a kind of cyclone firing that has, and high heat is imitated the low emission flue dust, the coal-fired smoke-removing boiler of strengthening of a kind of vertical whirlwind of no coal and region restriction.
For reaching above-mentioned purpose, the utility model can be realized by following scheme: the utility model comprises shell, water inlet pipe, outlet pipe, flue, horizontal water tube, fire grate and impact tube, and body of heater shell and flue are provided with fire door, remove cinder notch and air inlet; Be provided with annular hogging in flue between fire grate and the horizontal water tube, annular hogging is provided with the flame arch, is provided with ash-falling hole around the described annular hogging, and ash-falling hole is provided with the ash-falling hole lid; The flame arch radially is provided with fire jetting hole; Lateral wall is provided with secondary vane shape air compartment on flue, and secondary vane shape air compartment is provided with the pre-warm-air pipe of secondary wind and communicates with burner hearth by the overfire air jet on the furnace wall along the flue lateral wall; Louver is provided with primary air intake pipe and secondary air intake pipe and is connected with fire grate bottom and secondary vane shape air compartment respectively.The annular hogging bottom that is arranged between interior fire grate of flue and the horizontal water tube is taper, and the flame arch that is arranged on the annular hogging is a hemispherical, and set overfire air jet is two layers of setting on flue.Being arranged in the flue the annular hogging between the fire grate and horizontal water tube and flame, to encircle internal diameter identical.
The utility model has the advantages that; Structure uniqueness, simple, the long service life of technology, deashing is convenient, adopt taper and two combustion chambers of hemispherical, the fire box temperature height, burning is fully, quick heating, thermal efficiency height uses the utility model not limited by coal and region, and the multistage tangential secondary hot-air of air preheat makes imflammable gas be upright to rotary combustion in burner hearth, sufficient combustion, smoke medicining dust-removing effect is remarkable.
The drawing explanation:
Accompanying drawing is the utility model overall structure schematic diagram.
Now in conjunction with the accompanying drawings the utility model is described in further details:
The utility model comprises shell (16), water inlet pipe, outlet pipe, flue (15), horizontal water tube (13), fire grate (17) and impact tube (14), is provided with fire door at body of heater shell (16) middle part, and the bottom is provided with except that cinder notch and air inlet.In flue (15), be provided with the annular hogging (8) that the bottom is a cone space between fire grate (17) and the horizontal water tube (13), annular hogging (8) is provided with hemispherical flame arch (11), be provided with ash-falling hole (9) all around in annular hogging (8), ash-falling hole (9) is provided with ash-falling hole lid (10), and hemispherical flame arch (11) radially is provided with cylindrical fire jetting hole (12).Lateral wall is provided with secondary vane shape air compartment (5) in flue (15) bottom, and secondary vane shape air compartment (5) is provided with the pre-warm-air pipe of secondary wind (6) and is provided with overfire air jet (7) by flue (15) lateral wall along flue (15) lateral wall and communicates with burner hearth.Louver (1) is provided with primary air intake pipe (2) and secondary air intake pipe (4) and is connected with fire grate (17) bottom and secondary vane shape air compartment (5) with secondary air intake pipe (4) by primary air intake pipe (2) respectively.Control valve (3) angle can be controlled the size of primary air intake pipe (2) and secondary air intake pipe (4) blast and air quantity.
During use, give the interior air blast of louver (1) with air blast, wind evenly blasts fire grate (17) bottom through primary air intake pipe (2) with cold wind, another road cold wind blasts secondary vane shape air compartment (5) through secondary air intake pipe (4) earlier with secondary wind, be close to the pre-warm-air pipe of secondary wind (6) that is welded on flue (15) wall then, here, cold air is heated, and the air that is preheated is injected in the burner hearth at a relatively high speed through secondary wind nozzle (7).Secondary wind nozzle (7) is to divide two layers of height to be arranged in around flue (15) wall according to fluid mechanics principle according to certain altitude, angle, caliber, quantity, direction, shape.The secondary hot-air of injecting in the burner hearth makes combustible gas and flue gas in the stove be upright to the rotation rising, and makes fuel gas and O
2Strong agitation is mixed, cause chance that imflammable gas burns and the heated time that has prolonged flue (15), the particle that a part does not burn is along with the flue gas spiral rises, because centrifugal action drops to fire grate (17) surface, also have the part particle to be hit and get back to fire grate (17) surface and burn once more, played the smoke abatement and dust control effect by annular hogging (8).Flue gas is after coming out in the primary zone that is made up of flue (15), fire grate (17) and annular hogging (8), it is indoor to enter the second-time burning of being made up of annular hogging (8) and hemispherical flame arch (11) through annular hogging (8), at indoor imflammable gas that does not burn of primary combustion and the O that has more than needed
2Obtain a large amount of radiant heat again from red-hot annular hogging (8) and hemispherical flame arch (11), form distinctive gas-fired, played the smoke abatement and dust control effect.Spray from the circular radial cylindricality fire jetting hole (12) on the hemispherical flame arch (11) at the indoor clean-burning flue gas of second-time burning, wash away top horizontal fork and arrange intensive horizontal water tube (13) and the board-like heating surface of many backhauls, heat is fed water by the transmission of large tracts of land heating surface with prestissimo.Be the serpentine swing when sweep of gases horizontal water tube (13) and board-like heating surface, and the negative pressuren zone that big volume is arranged between hemispherical flame arch (11) and annular hogging (8), be folded in the speed-change process at flue gas, because of effects such as inertia, eddy current, gravity, the part coal ash is separated from flue gas on annular hogging (8), has also played the smoke abatement and dust control effect.Design has ash-falling hole (9), ash-falling hole lid (10) above the annular hogging (8), and when boiler normally moved, ash-falling hole lid (10) was not opened, and during cleaning, takes away ash-falling hole lid (10), and dust stratification falls in the ashcan by casting furnace grate (17) from ash-falling hole lid (9).Sweep of gases horizontal water tube (13) and the board-like heating surface of many backhauls pass through impact tube (14) at last and enter atmosphere by chimney.
