The purification heating furnace of the hot desulfurization of source pollution abatement

The present invention relates to the purification heating furnace of the hot desulfurization of a kind of source pollution abatement, source pollution abatement atmosphere new technology, i.e. burning purifier, separation of flow clarifier also is used in all coal furnaces, in all gas furnaces, in all oil burners, burning purifier, desulfurizing purifier, it in stove a kind of quirk burning structure of stopping thing that has, be adapted to all coal furnaces that contaminated environment is arranged, gas furnace, oil burner purification of combustion.Source in the heap formula fire coal, stage casing purification of combustion smoke abatement and dust control.Super-huge Coal powder spray burning boiler, various big, in, small-sized Coal powder spray stove or heap formula coal-burning boiler, various coal-fired furnaces, various kilns, the forging rolling heating furnace, various coal-fired smelting furnaces, melting furnace, reduction furnace, various mineral aggregate calcining furnaces, coal-fired civil boiler of all size or drinking water boiler, the all size coke oven, various coal-fired reverberatory furnaces, various coal-fired annealing furnaces, various box high temperature, middle temperature oven dry, heating furnace, various useless dirt incinerators, various large cars move the mineral aggregate smelting furnace, coal-fired big special mess stove, house coal gas kitchen stove, furnace cupola, oil burner, heat-conducting oil furnace, iron-smelting furnace, gas generator, thermal plating bath, magnesium, aluminium melting pond, heat treatment and various low-melting-point metal, nonmetal mineral aggregate or electrolysis, in the electric smelter.The coal-fired clarifier of coupling in coal-fired process, high temperature smoke abatement and dust control.Desulfurizing purifier; Desulfurizing agent is housed in the desulfurizing purifier, is used in all coal furnaces or stage casing in the various combustion furnaces or the static desulfurization of the xeothermic property of afterbody waste gas stream.Or be used in the steel ladle, ladle, solid soaks in the clarifier process desulfurization.

Existing coal-fired mode has old-fashioned or two kinds of improvement type slightly, this dual mode all has flue dust, sulfur dioxide effluxing now, and the waste coal, and dedusting mostly, desulfurization are water treatments, electricity wasting, waste water, make sulfur dioxide become the sulfurous acid thing, this water treatment has just become a position also pollutes again, and dry ash has become wet ash, aloft do not pollute, polluted on the ground or in the water, the sulfurous acid thing is a kind of strong material that corrodes, and moist processing is undesirable.Never the someone reported the rational faculty research that the coal-fired process mid-deep strata is inferior on coal-fired history, how the flue dust of coal in combustion process was burnouted, and how the thermal source in the coal was used the limit and skilful use heat energy, just coal had been fired it.Flue dust effluxed be decided to be should.An a kind of coal-fired theoretical generation of mistake passes a generation and wastes energy commanding, and all is this on the full earth.It is too unfortunate that the energy wastes.

Purpose of the present invention is exactly in order to overcome the deficiency of above-mentioned prior art, the purification heating furnace of the hot desulfurization of a kind of source pollution abatement is provided, assemble the coal combustion structure, or Coal powder spray burning structure, rational research in the existing coal-fired process has concrete difform coal-fired clarifier matching structure in coal-fired the enforcement again, and coal-fired clarifier 1 makes gasification combustion chamber or burning purifier be used for all coal furnaces again, shown in Figure of description Fig. 1～24, the pollution of be in operation no flue dust, innocuous gas.Coal furnace all belongs to existing structure, and having only coal-fired clarifier is new burning structure, and desulfurizing purifier is a new equipment.

The object of the present invention is achieved like this: transform all combustion furnaces, it is the transformation of coal-fired furnace cavity, the transformation of fuel oil burner hearth, the transformation of the transformation of combustion gas burner hearth or combustion gas cover, kitchen range stove, blast pipe inlet position on the internal combustion engine, warding off the thermal insulation fire-resistant material, especially mating clarifier quirk structure in the fire coal, 1 burner claims purification of combustion chamber, gasification combustion chamber, overheavy firing band again; 2 devulcanizers claim desulfurizing purifier, desulfurization pond, desulfurization chamber again.In coal furnace, spacious diffusing burning coal of all heap formulas or spacious the loosing of Coal powder spray are burnt coal, all should change heap formula gathering burning coal or Coal powder spray into and assemble burning.Flame is assembled in the effect of coal-fired clarifier, keeps the high-temp combustion point, has formed an overheavy firing band.Cigarette, dirt all burnout in the overheavy firing band.No matter be coal furnace or oil burner or gas furnace or internal combustion engine, do not adopt source high-temp combustion clarifier to burn smog, atmosphere can't clean.

For coal-fired clarifier, desulfurizing purifier are created a rational position in different bodies of heater, so, transform the partial combustion structure in all coal-fired bodies of heater to some extent, flame reaches the effect of purification of combustion after through an overheavy firing section in coal-fired process.Coal-fired clarifier is the quirk flame retarding construction of the gasification, and combustion again of the different shape that is combined into by a plurality of refractory products or metallic article or metal and refractory product; Desulfurizing purifier is the product structure that is combined into by dress desulfurizing agent and position-limiting part spare in refractory product or the metallic article, shown in Figure 1, the height at first position in various or all coal furnace burner hearths or length increases or the 0.2-0.8m that extends, 0.8-1.5m, 1.5-3m limits such as three, height in the horizontal boiler is constant, the position of increasing, longitudinal separation high low level stairstepping build one or multi-channel top arch, be that parallel longitudinal is covered with the shop at interval and is taking the thermal resistance flow between arch and arch, upper position or rear in the thermal resistance flow are combustion spaces, a perfect burning purifier is formed by one or multilayer are a plurality of in this space, the size in space, size at interval determines that according to the burner hearth size crater is 1/4th to 1/10th of a burner hearth quadrature.Coal-fired burner hearth is exactly first combustion chamber, can be lower than ground or equal with ground, inside and outside double combustion chamber structure or double combustion chamber's structure or double-furnace structure are up and down arranged, after-burner can extend to the flue inner segment of floss hole or double combustion chamber, front and back structure or be the structure of the two burning zones of high low level at three chamber structures about the bilateral of burner hearth or in a burner hearth, or at burner hearth through the combustion chamber to the inner segment of going into floss hole, mate suitable air quantity or moisture content, utilize the oxygen in the wind or in the water to burn fine coal crystal grain.The height of burner hearth top is strengthened or lengthening, many rounds, multilayer obstruct burner, protruding furred ceiling or accumulation of heat arch are installed above burner hearth or in the heating clamber of rear.Coal-fired clarifier quirk is exactly in the process of burner hearth source fire coal, and flame, flue dust, waste gas stream, air or water smoke is by an extra-high-speed temperature high pressure, and gasification, and combustion structure again between the Shun when being subjected to thermal resistance and flowing of narrow position.The principle of gasification, and combustion again be constant in all burning coal stoves, but the component shape of coal-fired clarifier is diversified, and narrow position is all arranged in the coal-fired clarifier, is that the shape and structure with body of heater, burner hearth changes.Be subjected to the burning structure again of choked flow by narrow position, a gorge.Coal-fired clarifier and desulfurizing purifier are used for oil burner or gas furnace equally, the shape of the block type widget in the desulfurizing agent shape of desulfurizing purifier, lumpiness and the coal-fired clarifier, and lumpiness is identical, all is many rounds, the multilayer barrier structure.

Adopt source high temperature coal clarifier or burning purifier to burn cigarette, dirt.In the combustion zone in all coal furnaces,, coal-fired clarifier, desulfurizing purifier are installed in certain rational position in the above-mentioned various coal furnace the shape that is transformed in the various coal furnaces shown in Figure of description 1-24.As long as coupling goes up coal-fired clarifier quirk structure, rationally air feed, just can play the effect of purification coal-burning smoke-less dirt for mist.Otherwise will the billowing atmosphere pollution of black smoke.

Leading portion from top to the heating clamber or molten bath to the chimney porch of coal-fired furnace cavity, in the zone of flame process, be referred to as quirk, the inner chamber of every quirk, the a certain angle of building or installing is multiple crooked, orphan's degree, vertical 180 ° of multiple bendings, hang joint mutually and stretch projection, hang projection, rectangular of quadrangle, porous plate, arcuate segment, convex cone, blade, little arch, the stove eaves, the constant temperature joint, fresh air inlet, many row's cylindrical voids or conical bore heat gathering cover, the both feet fulcrum, channel space all belongs to the parts of coal-fired clarifier, these parts are formed coal-fired clarifier miscellaneous, be used for coal furnace miscellaneous or all combustion furnaces, this cans be compared to the words the same reason of coming out as an article, it is endless chapter.

The position that coal-fired clarifier is installed in all coal furnaces, be from the source of burner hearth to the porch leading portion of flue, not having the flue dust discharging with heat utilization height, chimney is benchmark, selected shape or position.

The shape of coal-fired clarifier is miscellaneous, and every coal-fired body of heater that a kind of difform or different purposes are arranged just needs the coal-fired clarifier of a kind of style of coupling, just can eliminate flue dust and efflux.

The shape of coal-fired clarifier has: 60 types, be exactly 60 ° shape; 90 types, 180 types, the rest may be inferred by analogy; 390 types, be exactly the thermal resistance stream overheavy firing band structure of 3 90 ° lonely shape curve or how crooked shape, be divided into the internal-quirk heating furnace, parallel or vertical many flexure types quirk is arranged, this outer wall has fin or tooth, or outer storage heater heating furnace.The waste gas outlet of internal-quirk section of inner chamber in stove has circular or square or rectangular shape.The top of all fire coals or burner hearth all is added with accumulation of heat arch or protruding furred ceiling, and protruding furred ceiling also is thermistor, in the heating clamber of continuous or intermitten operation above, all be added with the accumulation of heat arch, also be storage heater.Coal-fired clarifier is exactly a kind of quirk structure in coal furnace, and wind, water, the mist of coupling are to press the every quadrature of burner hearth in the coal-fired furnace cavity, generally supplies with wind, water, mist with 0.2-0.6 kilowatt blower fan.Special burner hearth should strengthen wind supply quantity 1-1.5 or 2-3 kilowatt.

Coal-fired clarifier is a multi-functional controller, also makes storage heater, thermistor, heat melting device, thermal compressor, heat transfer device.In coal furnace, in the oil burner, in the gas furnace, can be arranged in burning purifier or be distributed in the top of burner hearth or upper and lower, front, rear, left and right in the heating clamber and carry out temperature in the constant heating clamber of accumulation of heat.

Wherein, used coal-fired clarifier parts are the various shapes of many formulas, be divided into monomer portion or combiner, a lot of difform of a kind of usefulness in other words conj.or perhaps, the purification of combustion structure of the pass shape that the single component of different angles is combined, thermal resistance flows coal-fired clarifier or burner, critical piece, rectangular or the section quadrangle base collection combining structure of parallelogram is arranged, tetragonal cross-section face width 0.02-0.1m, the long 0.04-0.2m of vertical section, rectangular length 0.1-1m or flat board or porous flat plate shape are combined into the parallel bending at 60-120 ° of angle, curved tearing open built the curved body shape of tearing open of Jianping row, it is curved that to tear length open be 0.02-0.05m, 0.05-0.1m, 0.2-0.5m, 0.2-0.5m parallel multilayer both forward and reverse directions staggered structure, its spread length is because of stove suiting measures to different conditions.Parallel curved tearing open is to combine with the thick fire resistive material product plate of 0.01-0.04, in the burner hearth or quirk of three kinds of Fuel Furnace, rectangular of cross section quadrangle has vertical arrangement or transversely arranged or vertical array or multidirectional arrangement, various arrangements all can be answered layer and be arranged, tear combination thermal resistance stream pass or vertical interior 180 ° of multiple crooked upright theory structures of tearing the coal-fired clarifier of thermal resistance stream pass open open at rectangular of quadrangle thermal resistance stream or parallel 90 ° of multiple bendings, in all coal furnace burner hearths, be constant in the quirk, Coal powder spray or heap formula fire coal, used how crooked quirk A, the heat supply distribution of many crooked quirks in heating clamber, be multi-faceted, many styles, have one-sided or offside or position, four directions or five orientation or six orientation layout, the heat supply direction heats object towards the center of heating clamber, how crooked quirk heat-supplying mode is smoke abatement and dust control in the fire coal.

From the inner segment of top to the toxic emission porch of coal-fired furnace cavity, all can establish coal-fired clarifier parts, every parts that coal-fired clarifier is housed just are called a combustion chamber, and one or more combustion chambers that couple together are called an overheavy firing band.The shape of coal-fired clarifier, also can be in desulfurizing purifier usefulness, the temperature difference position difference of just laying.

UTILIZATION OF VESIDUAL HEAT IN, the waste heat of every heating clamber rear end all should be at body of heater nearby at 600-1100 ℃, builds the calcining compartment of a 5-50T below the 1m of ground, or ground annealing furnace, preheating furnace, drinking water boiler, boiler, drying chamber.The first step of clean combustion in burner hearth to heating clamber; Second step was installed the clarifier parts at the porch of flue inner segment.Combination burner.And combustion-supporting with gravity-flow ventilation or blower fan air feed, eliminate the pollution of flue dust, and improved heat utilization, utilized waste heat.

The annealing furnace of glass factory or preheating furnace will utilize waste heat, and the height of stove will be lower than ground level or protrusion ground 0.6-1m gets final product, and every waste heat calcining mineral aggregate stove that utilizes designs as far as possible at below ground.Or be designed to revolution cellar for storing things stove or erect on the ground, if the shortage of heat of waste heat, can set up the little burner hearth that a coal dusts at waste heat lighting-up tuyere place or heap the coal-fired furnace cavity of formula, it is the same that the Coal powder spray combustion heat supplying is smelted the principle that various metals, furnace of calcium carbide calcine various mineral aggregate stoves with Coal powder spray, and structure is also close.Calcining furnace adopts the middle and lower part central authorities' Coal powder spray or the interior Coal powder spray heating of the noisy pavilion of side of stove, also cries the combustion chamber of Coal powder spray.

Rare-earth smelting earlier sinters reduction blocks (semi-finished product) into crucible or perpendicular collection crucible or the perpendicular collection of the moving pre-hotpit stove of car crucible in the stove of cellar for storing things, the back becomes rare earth alloy in the Coal powder spray furnace refining of smelting calcium carbide.

Smokeless ignition furnace is used for the coal-fired clarifier top, back upper end of interrupted coal-fired furnace cavity, and there are low ignition point, the poly-warm device sheet of low-melting timing, the rectangle thin slice of its thickness 0.01-0.02m in the upper back.

Interrupted coal-fired operation needs two-wheel transfer point firearm (ignition furnace) of eliminating flue dust of coupling, the crater of two-wheel transfer point stove is to insert in the interrupted coal-fired furnace cavity coal feeding hole, when being warming up to 800 ℃, interrupted coal stove thorax withdraws the transfer point firearm, weldering clothes-hook awl on the boiler inner wall, with clay the porous brick bat is pasted the jail, the thickness 0.02-0.04m of hole brick, weldering nail awl pastes refractory material on the water beam in boiler, the water pipe, fulcrum on water beam or water pipe, the porous grillage in the above.

Parts 81 in the coal-fired clarifier are multi-direction, multiposition arrangements, can be used for the top of all coal-fired furnace cavities or burner hearth, are smoke abatement and dust control in the fire coal, improve heat utilization, and the thermal resistance of round more than 81, multilayer intercept assembles overheavy firing.

The top of stoking fire door is a kind of row's air feed pipe, and the top of air feed pipe is row's water supply mist pipe.The length of water smoke pipe is 1/2nd or 1/4th of burner hearth length, tube wall be to perforate, down be weeper, on be defogging hole or air feed pipe, water smoke pipe combined or the shower nozzle of sprayer is stretched into operation arbitrarily in the burner hearth.The top of water smoke pipe is a window, and what add in heaping the formula coal-fired furnace cavity is the water coal, and being in operation is the stoking air feed, and the sled fire supplies water, usual two stopping.

In boiler and other body of heater, look for a rational purification of combustion position for giving coal-fired clarifier, desulfurizing purifier, the hot-water line in the former body of heater also will just can reach the effect of boiler fired coal purification of combustion with coal-fired clarifier shape changing position.For coal-fired clarifier in different bodies of heater, go into the stage casing in the floss hole behind source, top to the heating clamber or the molten bath of coal-fired furnace cavity, all can establish coal-fired clarifier, as long as it is rational in infrastructure, can both play good equally coal-fired clean-up effect, for administering the flue dust in the fire coal, the sulfur dioxide pollution atmosphere, must create an appropriate rational position in body of heater, for coal-fired clarifier, so, source in the fire coal, stage casing purification of combustion smoke abatement and dust control, will transform the partial combustion structure in all coal-fired bodies of heater to some extent, flame reaches the effect of purification of combustion after through an overheavy firing section in coal-fired process.Form by coal-fired clarifier and desulfurizing purifier, facilitated UTILIZATION OF VESIDUAL HEAT IN in all coal furnaces with coal-fired clarifier, and formed a bigger desulfurization zone, coal-fired clarifier is the quirk flame retarding construction of the gasification, and combustion again of the different shape that is combined into by a plurality of refractory products or metallic article or metal and refractory product, coal-fired clarifier quirk is exactly in the process of burner hearth source or stage casing fire coal, flame, flue dust, waste gas stream, air or water smoke are by an extra-high-speed temperature high pressure, and narrow position is subjected to thermal resistance stream, back speed enters the position of a broad, gasification, and combustion structure again between a Shun.Shown in Fig. 1～24, all be disposable two the step burning structure double combustion chamber be the coal first step most flue dust of unburned in circular square or rectangular burner hearth 3 combustion process, go on foot in purification of combustion quirk structure through second again, coal-fired clarifier 1 is exactly a quirk miscellaneous, cry extremely end of burning again in gasification combustion chamber, the gasification, and combustion band again, constitute two combustion processes, be disposable two step burning structures.Inside and outside double combustion chamber structure or double combustion chamber's structure or double combustion chamber, front and back structure or be the structure or an independent common burner hearth of the two burning zones of high low level at three chamber structures about the bilateral of burner hearth or in a burner hearth are up and down arranged, intercept burner by many rounds, multilayer, can be useful for all coal furnaces.Be constant in all coal furnaces, but the parts of coal-fired clarifier, shape does not limit, and is varied, changes with the shape and structure of body of heater, burner hearth 3.Coal-fired clarifier is used for oil burner or gas furnace equally; Burner hearth 3 has circular or square or rectangle.The protruding thermal resistance flow pattern of hanging in burner hearth top at interval in length and breadth in the coal-fired clarifier of stratum arc curve.Coal-fired clarifier all is because of burner hearth suiting measures to different conditions, with Fig. 1 is the basic element of character, the interior sectional area of quirk, make one little one greatly one section quirk or one little one big multistage section the quirk structure of thermal resistance stream purification of combustion, manufacture the coal-fired clarifier of shape of all kinds with Fig. 1; That a kind of coal-fired clarifier no matter, it all is crucial giving the size of the coal-fired clarifier in stage casing, source, quirk position air feed, water supply mist amount, also is crucial.Wind, mist are interrupted or regulate continuously and supply with, and see the high point of heat build-up in the burner hearth just is installed in coal-fired clarifier where somewhere.Parts installation interval distance in the coal-fired clarifier is fixed because of need, is vertical or horizontal or is tilted to distribution.Common coal-fired clarifier is located at top or rear end or top, rear end or the both sides or the flue entrance place section at coal furnace top, and the number of plies of coal-fired clarifier has 1 layer or sandwich construction, in various boiler scopes, has vertical heater shape crater soaring.No matter the quirk of horizontal chamber furnace (oven) shape burner hearth is circular or rectangular crater, have up or down or elbow flat fire shape, one-sided or branch craters such as bilateral or circumference are held before, during and after quirk all cleaning door, the direction position of various burners, the spacing of the size of the specification of the size of crater 20 and coal-fired clarifier 1 and the height of 1 installation site and arc curve wall 7 are to determine according to the calorific intensity size of coal-fired furnace cavity.7 have three kinds of circle or square frame shape or rectangular shaped as frames, and square or rectangle also belongs to a class of arc curve, no matter the size of coal-fired furnace cavity, shape, arc curve again the principle of gasification, and combustion be the same.The first half of hearth wall more than 2/3 is 20～40 ° of arcs or is taper type or square.The wind of coal-fired clarifier 1 air inlet 4 and fire bars below all be supply with by air blast or do not have a blower fan structure.In arcwall 7, clip thick vermiculite power of one deck 50～100mm or mineral wool insulation material.Minimum burner 20 is φ 50mm, and maximum burner 20 is φ 1m.20 have circular or square or three kinds of rectangles.Can be installed in below ground at the bottom of the heating-furnace or ground level any one position with upper furnace body, Fig. 1-2 4 is mullite or corundum or aluminous refractory or graphite and fire clay or metallic plate, the coal-fired clarifier of making.

In the coal-fired clarifier 1 of spherical hearth single or multiple steam vents 4 are arranged, two kinds on single row or multiple rows type is arranged.Square or rectangle body of heater is that full-bridge is vertically arranged, get angry hole 4 entirely in the two sides or the single side face of bridge, position at the body of heater exterior combustion chamber of various coal furnaces has one to gang up blast pipe 4, blast pipe to the air blast that 4 UNICOMs under the space for collecting ashes in a stove is given coal-fired clarifier below air-supply in the burner hearth, any one direction hot wind supply that can be in burner hearth or the comprehensive air feed of wall or intermittently regulate air feed with the valve on the air supply line, toward the interior air feed of burner hearth, there are two kinds for mist: 1, common air feed; 2, hot wind supply, hot blast enter in the burner hearth combustion-supporting after being the air channel circulation of cold wind in burner hearth five walls.Or from the top comb air feed of coal feeding hole, fire door or in the furnace wall, gang up to air feed in the burner hearth from space for collecting ashes in a stove, or go in the floss hole place or the end of smelting the molten bath is gone into interrupted air feed or gravity-flow ventilation in the floss hole place to heating clamber, in a word, wind supply quantity is proper to get final product; Dirt container or jar are ash accumulating chamber, and circle or square is arranged, and inwall has the thick refractory material of one deck 10mm, the internal volume 1～3m of dirt container ³, 3～5m ³The dirt container is to be installed in a close position side by side with the body of heater double combustion chamber, the dirt outlet of container is joining the inlet of blower fan, can outreach the coal-fired clarifier 1 of turnover, 1 has circle or semicircle or diving tower shape or square or five kinds of shapes of rectangle, all belong to arc curve and keep the structure of high burning-point, 1 of coal-fired clarifier or be arranged in above the coal-fired furnace cavity 3, folding rotary type fire bars is installed in lower furnace portion
