The specific embodiment
As shown in Figure 1, spraying type sludge anhydration burning filter is mainly made up of relevant portions such as sludge conveying system, burning back-up system, CIU, residual neat recovering system, flue gas purification system and remaining cigarette exhaust systems.
Sludge conveying system is mainly made up of sludge delivery pump (1) and sewage sludge feed device (2), the mud that sludge delivery pump (1) is collected sewage disposal is transported in the hopper of sewage sludge feed device (2), and sewage sludge feed device (2) is delivered to the mud in hopper in CIU by screw feeder.
Burning back-up system is mainly made up of coal pulverizer (3), oxygenating blower fan (4) and second-time burning oxygenating blower fan (19), coal pulverizer (3) carries out efflorescence to coal, then delivered in CIU by delivery pump, abundant in order to guarantee pulverized coal friring, oxygenating blower fan (4), for CIU carries out oxygen infusion, improves burning of coal rate.
CIU is the core apparatus of the harmless CIU of mud, the quality of CIU is related to final emission result, CIU is mainly made up of sludge incineration device (6) and secondary combustion chamber (7), be equipped with in their inside and the pulverized coal gun (5) that burns back-up system and be connected, logical pulverized coal gun (5) burns inner mud, carries out harmless treatment.In order to guarantee that secondary combustion chamber (7) internal pressure, in normal range (NR), quick-fried stove situation does not occur, be provided with venting (8) in the upper left-hand of secondary combustion chamber (7).Mud enters into sludge incineration device (6) inside by sewage sludge feed device (2), burn first by pulverized coal gun (5), then along with the rolling of sludge incineration device (6), mud after burning is sent in secondary combustion chamber (7) and carries out second-time burning, lime-ash after burning enters into ash discharging gear (9) by the cleaning door of secondary combustion chamber (7) bottom and is discharged to the external world, and the flue gas of generation enters into flue gas purification system by the cyclone dust collectors (10) at secondary combustion chamber (7) top.
