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 Trident Type and is welded on barral of a gun.
As preferably, described protection tube puts and is provided with the cooling air import that cooling air is provided for atomizing lance, and the head end of this protection pipe box is a little less than the jet hole of atomizer.
As preferably, between described compressed-air atomizer and percolate nozzle, be L-type and distribute.
Beneficial effect of the present invention is: abundant resolution process garbage filter stoste, or further process the concentrate that other processing modes produce, avoid producing secondary pollution; Compare other processing mode, its construction, operation, maintenance cost are low, and floor space is little, and the degree of automatically controlling is high, easy to operate; Due to employing atomized spray, make percolate evenly evaporation in burner hearth, by the extra of garbage fuel, supplement simultaneously, to guarantee to burn and carry out within the scope of nominal situation, the generating efficiency of Bu Huidui power plant produces materially affect; According to burning situation, carry out the adjusting of emitted dose, make the cooling of burner hearth appropriateness, reduce the infringement of excess Temperature flue gas to burner hearth, the coking of minimizing heat convection face is had necessarily and benefited;
1, can not change burner hearth smoke components, can not increase the load of gas cleaning part;
2, on the impact of gas cleaning sub-load in condition range;
3, be conducive to reduce the amount of nitrogen oxides of furnace outlet flue gas;
4, contribute to increase waste incineration amount.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done to detailed introduction: as shown in accompanying drawing 1 to 3, the present invention by a compressed-air atomizer 1, percolate nozzle 2, flange 3 add sealing ring 7, protection pipe box 4, barral of a gun 5, an atomizer 6 forms; Compressed-air atomizer 1 is screwed in to the major part of percolate nozzle 2 by screw thread; again barral of a gun 5 is screwed in to 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; by screw 8, fixedly prevent landing; on the tapped external screw thread that is screwed in 5 one, barral of a gun of atomizer 6, tighten, 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 Trident Type and be welded on barral of a gun 5, its Main Function is to control barral of a gun 5 and protect the gap of pipe box 4 even, and cooling-air can evenly be passed through.
Double-flow spray gun atomizing principles: percolate mixes in shower nozzle with certain pressure by compressed-air atomizer 1 by percolate nozzle 2, compressed air, produces very tiny atomizing particle, and 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, provide a certain amount of cooling air for spray gun; 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 μ m, spray gun is arranged on incinerator, temperature is installed and is about 1200 ℃; 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 adopts and uses mixedly compressed air with compressed air.
After leachate recycle, be convenient to control and burn furnace exit temperature, slowed down boiler coke.Extend the equipment cycle of operation, be conducive to operation steady in a long-term, improved economic benefit.Leachate recycle mouth is arranged in incinerator outlet side wall both sides, basic parallel with overfiren air port, every side is arranged two atomizing lances, while returning spray, percolate clear liquid mixes with compressed air with the whole burning furnace outlet of vaporific covering, with the abundant combination of high-temperature flue gas, reduced flue-gas temperature, through actual motion, when returning spray system input rear hearth maximum temperature, can float downward 30 ℃, for the control of furnace exit temperature provides good control device, overtemperture control when especially high to refuse thermal value provides means more easily, slowed down coking speed, extended 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 requirement of the present invention.
