The specific embodiment
As shown in Figure 1, sludge anhydration burning filter is mainly comprised 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 comprised 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 comprised 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 by delivery pump, delivered in CIU, 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 comprised of sludge incineration device (6) and secondary combustion chamber (7), in their inside, be equipped with 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, in the upper left-hand of secondary combustion chamber (7), be provided with venting (8).Mud enters into sludge incineration device (6) inside by sewage sludge feed device (2), by pulverized coal gun (5), burn first, 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, the cleaning door of lime-ash after burning by secondary combustion chamber (7) bottom enters into ash discharging gear (9) and is discharged to the external world, and the flue gas of generation enters into flue gas purification system by the outlet flue at secondary combustion chamber (7) top.
For the heat that CIU is produced enters recovery, in the coiling of the outside of secondary combustion chamber (7), there is radiating tube (17), radiating tube (17) and water tank (18) form the residual neat recovering system of the harmless CIU of mud.
