Fig. 9 and Figure 10 is please referred to, if the column for smoke purification 70 includes a purifying tube 71, clean cigarette disk 72, a draining
73 and one stair 74 of valve.The purifying tube 71 is cylindrical tube, and is made of steel plate.If the clean cigarette disk 72 is pacified respectively
In the purifying tube 71, the inner wall of the purifying tube 71 corresponds to each net cigarette disk 72 and is convexly equipped with stent (not shown meaning), institute
Stent is stated to support corresponding net cigarette disk 72, such as can be made of several ribs.Each net cigarette disk 72 is respectively by two halves
Disk 721 forms, and in the present embodiment, the two halves disk 721 is fixed together by the rotation of hinge 722, wherein half
Disk 721 offers several exhaust smoke holes 7211, and another semi-disc 721 is provided with scavenging material, and the scavenging material is absorbing
Particle in flue gas can be flannelette, activated carbon etc..If described in installation during clean cigarette disk 72, in the parallel purifying tube 71
On the direction of mandrel, semi-disc 721 in adjacent net cigarette disk 72 with several exhaust smoke holes 7211 on another net cigarette disk 72 with
The semi-disc 721 of scavenging material is staggered, it is preferable that if the clean cigarette disk 72 is arranged in parallel.In order to facilitate the installation of
The net cigarette disk 72, two windows 711 are further opened on the side wall of the purifying tube 71, and the stair 74 are mounted on the purifying tube
On 71 outer wall, staff can be installed across window 711 to the purification by the stair 74 of creeping, and by net cigarette disk 72
In cylinder 71.The drain valve 73 is mounted on the purifying tube 71, and close to the bottom of the purifying tube 71；Preferably, it is described
If clean cigarette disk 72 is mutually parallel, if the clean cigarette disk 72 is equidistantly distributed on the purifying tube 71.
One end of the smoke exhaust pipe 641 is mounted on the purifying tube 71, and the bottom of the close purifying tube 71, to
60 processed flue gas of convection current dust-extraction unit is drained into the column for smoke purification 70；The top of the purifying tube 71 is equipped with described
Smoke exhaust pipe 90, the other end of the smoke exhaust pipe 90 stretch into the fume high-temperature process tank 15, to will be via the gas cleaning
70 processed flue dust of tower is discharged into the fume high-temperature process tank 15.The smoke exhaust pipe 641 processes convection current dust-extraction unit 60
Flue gas be discharged into the column for smoke purification 70, if successively after the clean cigarette disk 72, the fine particle in flue gas is by net cigarette
Scavenging material absorption on disk 72, then drains into the fume high-temperature process tank 15, the flue gas via the smoke exhaust pipe 90 again
High-temperature process tank 15 is to pyrolytic toxic gas, such as bioxin.
One preferable working method of non smoke refuse burning system 100 of the present invention is as follows：Feed arrangement 11 by rubbish send to
The feed bin 121 simultaneously closes off the grille door 123, and the rubbish do not dried is prevented to be directly entered the combustion chamber 133；It uses
During non smoke refuse burning system 100, the rubbish in combustion chamber 133 is lighted by igniting chamber 137, the heat that incineration firing generates
Air-flow is spread rapidly under the action of flue gas recirculation room 134 and scattered chimney 140, and fast with fresh air that igniting chamber 137 is come in
Speed is sufficiently mixed, it is ensured that rubbish can fully burn, without adding any oxidizer；In addition, smog in combustion chamber 133 via
The effect of the exhaust structure 80 is discharged into the dust catching case 20 by the smoke exhaust pipe 210, meanwhile, in the combustion chamber 133
Heat the rubbish in the feed bin 121 is toasted by the grille door 123 so that the vapor in rubbish passes through institute
It states steam delivery pipe 122 and is discharged into the dust catching case 20, vapor and smog pass through successively after entering the dust catching case 20
It crosses the blocking of several interception structures 25 and will be fallen in water after the dust interception of larger particles in smog, such larger particles ash
Flue gas stream after dirt is removed is evacuated to the tar processing room 40 by the exhaust structure 80.
After flue gas stream enters the tar processing room 40, passed through after several first water-cooling walls 45 of lower box 418 successively
Several second water-cooling walls 46 of upper box 417 are crossed, heat smoke reduces hydrocarbonization because of the effect of water-cooling wall, flue gas fast cooling
The regeneration of the harmful substances such as object, carbon monoxide and nitrogen oxides particularly bioxin is closed, meanwhile, heat smoke forms tar to the cold
Mist, tar fog wrap up the impurity submerged in flue gas, treated flue gas will then be drained into the rotational flow settlement tank 50
In.
Flue gas sequentially enters the lower tank 51 of rotational flow settlement tank 50, due to the central axial alignment side of the smoke outlet of lower tank 51
Wall, and the water level of lower tank 51 and the difference in height of central shaft be in ± 4cm, thus when flue gas sprays the smoke exhaust pipe 49 drive water
It is rotated along side wall, while in water containing under the action of CaO, granule foreign and element sulphur in flue gas are removed, using
The effect again of upper tank body 52, granule foreign and element sulphur in flue gas are efficiently removed, and then processed flue gas drains into
The convection current dust-extraction unit 60.
Flue gas is vertically sprayed into via smoke exhaust pipe 521 in the water tank 61 in the convection current dust-extraction unit 60, and flue gas is by water tank 61
The blocking of surrounding and the condensation tube to the top of water tank 61 recoils, then the flue gas sprayed with smoke exhaust pipe 521 or communicating pipe 69 is condensing
Fierce head-on collision, is removed the oil reservoir for being wrapped in dust surface in cylinder, so as to enable the quick submerged of dust, by place
Flue gas after reason is discharged into again in the column for smoke purification 70.
After flue gas enters column for smoke purification 70, if after sequentially passing through the clean cigarette disk 72, due on net cigarette disk 72
Under the action of scavenging material, the flue dust in flue gas passes through after being blocked again drains into the fume high-temperature processing by the smoke exhaust pipe 90
In tank 15, due to dissipating the effect of chimney 140, the indoor heat that will burn is led in the fume high-temperature process tank 15 so that cigarette
Temperature in gas high-temperature process tank 15 is very high, it is sufficient to by the toxic gas in flue gas, after Ru bioxin decomposes, then by concentration it is low,
Free of contamination air-flow is discharged via the chimney 16.
The present invention has following effective effect：
1. the drying room bottom of incinerator is provided with stock guide and grille door, can make in landfill leachate flowing in combustion chamber
Burning, prevents poisonous and harmful liquid directly excessive, pollutes；Grille door can also make the hot spoke that the rubbish to burn generates
It penetrates and high-temperature baking directly is carried out to unburned rubbish, remove moisture removal, garbage drying is got ready for next round burning.
2. the igniting chamber, flue gas recirculation room and scattered chimney in incinerator under the promotion of thermal current, form flue gas turbulent flow, make
The indoor flue gas that burns quickly is spread, it is ensured that rubbish can fully burn, and rubbish burns rubbish, any combustion-supporting without adding
Object, garbage disposal cost reduction.
3. dust catching case, the use of tar processing room, rotational flow settlement tank, convection current dust-extraction unit, purifying column, effectively remove
Various impurity in flue gas make flue gas reach " zero smog " discharge.
4. fume high-temperature process tank is arranged on the top of combustion chamber, the heat radiation of combustion chamber is directly to fume high-temperature process tank
It is toasted, makes the temperature in fume high-temperature process tank tank up to 1000 ° or more, convenient for generating bis- Evil during removal waste incineration
English.
