Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of dual flow design that adopts, percolate and compressed air mix in shower nozzle with certain pressure, produce the atomizing lance that very tiny atomizing particle has long service life.
The object of the invention is to have come by following technical solution, leachate recycle mouth is arranged in and burns thorax outlet of still side wall both sides, parallel with overfiren air port, two atomizing lances are arranged in every side, described atomizing lance is made up of compressed-air atomizer, percolate nozzle, flange, protection pipe box, barral of a gun, atomizer, described compressed-air atomizer is screwed in the major part place of percolate nozzle by screw thread, described barral of a gun is screwed in the microcephaly place of percolate nozzle by screw thread, and tapped one of described atomizer is tightened against on the external screw thread of one, barral of a gun; Described barral of a gun is fixed with a flange by welding manner, and this flange sleeve has sealing ring; Protection pipe box has a headgear of installing hole on this flange, and is screwed and prevents landing.
As preferably, described barral of a gun is provided with locating dowel, and this locating dowel is positioned at the front end of barral of a gun, and near atomizer, is welded on barral of a gun in Trident Type.
As preferably, described protection tube puts and is provided with as atomizing lance provides the cooling air import of cooling air, and the head end of this protection pipe box is a little less than the jet hole of atomizer.
As preferably, distribute in L-type between described compressed-air atomizer and percolate nozzle.
Beneficial effect of the present invention is: can abundant resolution process garbage filter stoste, or the concentrate that produces of other processing modes of process further, avoids producing secondary pollution; Compare other processing mode, it is built, operation, maintenance cost is low, floor space is little, and automatic controlling extent is high, easy to operate; Owing to adopting atomized spray, percolate is evenly evaporated in burner hearth, supplemented by the extra of garbage fuel simultaneously, guarantee that burning is carried out within the scope of nominal situation, materially affect can not be produced to the generating efficiency of power plant; Carry out the adjustment of emitted dose according to burning situation, make the cooling of burner hearth appropriateness, reduce the too high flue gas of temperature to the infringement of burner hearth, have the coking reducing heat convection face and necessarily benefit;
1, burner hearth smoke components can not be changed, the load of gas cleaning part can not be increased;
2, on the impact of gas cleaning sub-load in condition range;
3, the amount of nitrogen oxides reducing furnace outlet flue gas is conducive to;
4, contribute to increasing waste incineration amount.

Detailed description of the invention
Do detailed introduction below in conjunction with accompanying drawing to the present invention: as shown in accompanying drawing 1 to 3, the present invention adds sealing ring 7, by a compressed-air atomizer 1, percolate nozzle 2, flange 3 and protects pipe box 4, barral of a gun 5, atomizer 6 to form; Compressed-air atomizer 1 is screwed in the major part of percolate nozzle 2 by screw thread; again barral of a gun 5 is screwed in the microcephaly of percolate nozzle 2 by screw thread; then the fixed position that flange 3 is fixed by welding in barral of a gun 5 puts sealing ring 7; protection pipe box 4 has a headgear of installing hole on flange 3; fixedly landing is prevented by screw 8; the tapped external screw thread being screwed in 5 one, barral of a gun of atomizer 6 is tightened, and atomizer 6 is a little more than protection pipe box 4.As shown in Figure 4, described barral of a gun 5 is provided with locating dowel 51, and this locating dowel 51 is positioned at the front end of barral of a gun 5; and near atomizer 6; be welded on barral of a gun 5 in Trident Type, its Main Function is the gap uniformity controlling barral of a gun 5 and protection pipe box 4, and cooling-air is evenly passed through.
Double-flow spray gun atomizing principles: percolate is mixed in shower nozzle with certain pressure by compressed-air atomizer 1 by percolate nozzle 2, compressed air, produce very tiny atomizing particle, pre-designed spray site in burner hearth, carries out spray combustion evaporation.Spray gun is equipped with protection pipe box 4 simultaneously; by cooling blower for spray gun provides a certain amount of cooling air; guarantee that spray gun can stable operation in hot environment; the atomization ability of separate unit percolate spray gun is 0 ~ 1.5t/h; atomizing particle size 50 μm, spray gun is arranged on incinerator, installs temperature and is about 1200 DEG C; atomizing lance adopts specific alloy material to make, and has long service life.Percolate pump discharge: 15 ~ 20t/h outlet pressure: 1.2MPa, percolate return-spraying system should have good load adaptability.System should guarantee that percolate can not be flushed on incinerator housing.Percolate spray gun cooling air is from incinerator cooling blower.The specified blast of incinerator cooling blower is 2300Pa.Percolate atomization compressed air adopts and uses mixedly compressed air.
Be convenient to after leachate recycle control to burn furnace exit temperature, slow down boiler coke.Extend the equipment cycle of operation, be conducive to steady in a long-term operation, improve economic benefit.Leachate recycle mouth is arranged in incinerator outlet side wall both sides, basic parallel with overfiren air port, two atomizing lances are arranged in every side, returning percolate clear liquid when spraying mixes with the whole burning furnace outlet of vaporific covering with compressed air, fully be combined with high-temperature flue gas, reduce flue-gas temperature, through actual motion, 30 DEG C can be floated downward when returning spray system input rear hearth maximum temperature, control for furnace exit temperature provides good control device, especially means are more easily provided to overtemperture control during refuse thermal value height, slow down coking speed, extend the main equipment cycle of operation.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
