Description
Technical field
The utility model relates to the equipment of the removing or the processing of combustion products or combustion residue, relates in particular to a kind of device from circulation area removing solid recrement dust stratification, is applied to the cleaning field on residual heat boiler for exchanging heat surface.
Background technology
At present in various industrial production field, need a large amount of energy resource consumptions, in the production process by various thermal power transfer equipment, with producing and unemployed heat energy in energy equipment and the chemical reaction equipment, and can produce a large amount of various forms of waste heats in process of production, the source of waste heat mainly contains the industrial exhaust gas waste heat, the waste heat of high-temperature product and slag, the waste heat of cooling medium, what generate in the chemical reaction process abandons heat, combustible exhaust gas, waste liquid, the heat energy of waste material and waste vapour, the waste heat of waste water, and the evenly heat efficient of Industrial Boiler has only 67%, remaining energy passes through the useless fume emission of high temperature in the middle of atmosphere, causes great waste.So the UTILIZATION OF VESIDUAL HEAT IN of boiler industry at present is to be a important topic in energy-conservation at present, it has very high economic benefit and social benefit.
And a kind of in the smelting furnace UTILIZATION OF VESIDUAL HEAT IN that the kettleman the pines for the sparetime amateurish heat utilizations that are various kettleman, be converted into other energy by used heat that smelting furnace the is discharged heat energy by waste heat boiler, directly go to drag other mechanical devices and heat supply as electric energy, steam energy or as power, be widely used in the amateurish heat utilization of the kettleman field.In the smelting furnace UTILIZATION OF VESIDUAL HEAT IN (particularly ferroalloy smelting) but at present, running into cumbersome is that residual heat boiler for exchanging heat surface ash-clearing technology is efficient inadequately, reliably, its main cause is as follows: the waste gas of smelting furnace contains the superfine dust of a large amount of particles, very big adsorptivity is arranged, greatly influence heat exchange efficiency after being bonded at the heat exchange surface of waste heat boiler.And owing to nearly 500 ℃ ~ 600 ℃ of operating environment temperature, make traditional waste heat boiler ash-clearing technology, all be difficult to clean clean set of heat exchange tubes surface as steam blowing, compressed air purging, rapping, shock wave and sound wave cleaning etc., if these dust dust stratifications can not in time be cleared up, not only influence the energy-saving efficiency of waste heat boiler greatly, even can cause security incident.At present only on data, introduce external useful shot-peening method and can remove the dust that this kind particle is thin and adsorptivity is strong, so-called shot-peening method is that the heat exchange surface of the steel ball bump waste heat boiler that utilizes to fall down to topple over is aloft taken away dust, not only this cover system needs large-scale lifting, separation, evenly distributes and mechanism such as steel ball recovery, and owing to little steel ball is constantly pounded on set of heat exchange tubes, this system operation time has been grown, be easy to make set of heat exchange tubes of waste heat boiler damaged, cause accidents such as leaking, leak vapour and electric leakage.
Publication number CN2430616, the Chinese patent of open day 05 month 16 days calendar year 2001, a kind of weak explosion wave dust remover, be a kind of online removing ash of boiler decoking equipment, be mainly used in different types of dust stratification of removing the various heat convection faces of boiler smoke side, be applicable to oil oven and coal stove, be specifically related to a kind of flame accelerator.The weak explosion wave dust remover is evenly mixed in gas mixer through flow system by combustion gas and air, is lighted a fire by the high energy electric spark igniter in the igniting chamber.Flame is through propagating and cause appropriate pressure pulse fast in the flame accelerator behind the ignitron, export shock wave by the shock wave emission port of the shock wave transmitting tube side in the flame accelerator then, and being attended by the impact of high velocity air to the dust stratification face, dust stratification and cinder leave the dust stratification surface under the effect of these two kinds of factors.
Publication number CN201074823, open day on 06 18th, 2008 Chinese patent, a kind of High-energy Gas Pulse Sootblowers that is used for boiler, wet steam generator is made up of acceleration pulse generator, acetylene gas and air supply system; Acceleration pulse generator top is gas mixer chamber, and the bottom is the detonation chamber, and lower end, detonation chamber is welded with the mist conduit, and catheter proximal end is provided with the accelerator pulse nozzle; Gas mixer chamber one side is welded with the mixing point fire tube by the mist conduit, and the one side is provided with high-voltage ignition transformer, and the lower end is connected with the mist pilot chamber of detonation chamber one side, is provided with the high energy gas burning torch in the mist pilot chamber.Acetylene gas is connected with the mixing point fire tube of acceleration pulse generator respectively with air supply system.
Though above-mentioned patent can be removed the obstinate dust dust stratification on the boiler effectively, but, this patent palpus combustion gas itself and air light because evenly being blended in gas mixer through flow system, there is certain potential safety hazard, and can not be used for the residing high-temperature work environment of the utility model and little the dust stratification effectiveness of high absorption affinity.
Publication number CN2906351, open day on 05 30th, 2007 Chinese patent, a kind of turbine drives low frequency efficient acoustic wave dust remover, its by phonocatheter, housing, moving plate, still, axle, turbine for mainly to form.Housing by the collection chamber and the rear portion turbine room at the sounding chamber of the front portion that is interconnected, middle part and be positioned at the turbine room top and and the inlet plenum of its connection form.The collection chamber sidewall has oil filler point and instrument hole, and internal fixation has bearing holder (housing, cover), and two ends are equipped with bearing in the cover, are installed with one in the bearing, and the bearing holder (housing, cover) sidewall has through hole and oil filler point is communicated with.The shaft rear end interlock has turbine, and front end is with dynamic and static, and the moving plate front end is equipped with the antirust cover of spindle nose.End cover is stamped in the turbine room rear end.The inlet plenum lower surface has through hole, and front side wall has the adjusting bypass, and both are adjacent, and all is communicated with turbine room, at both active frequency adjustment sheets that is connected with of upper end intersection.Sounding chamber front end is communicated with phonocatheter.
This device can produce the sound wave of low frequency, high energy efficiency, and the dust stratification of boiler internal heating surface is removed.But this patent can not tackle that to contain a large amount of particles superfine and the dust of the smelting furnace waste gas of very big adsorptivity is arranged, and this apparatus structure is comparatively complicated, the cost height.
In sum, press for a kind of clearing apparatus that can clean the dust that particle is trickle, adsorptivity is strong under hot environment effectively earlier, this matching requirements is safe and reliable, and can not produce extra the pollution to surrounding environment.
