Description
Technical Field
The utility model belongs to the technical field of slag discharging devices, and particularly relates to a novel slag discharging device of a household garbage pyrolysis gasification furnace.
Background
The household garbage is grabbed out of the garbage pool by a travelling crane and a hydraulic grab bucket and put into a receiving hopper above a rotary feeder, a sealing door is opened, the garbage enters the rotary feeder, the rotary feeder rotates under the driving of a variable frequency motor and a gear transmission device, the garbage is thrown into the vertical household garbage pyrolysis furnace, the amount of the garbage entering the furnace is continuously adjusted by changing the rotating speed of the variable frequency motor, and the household garbage is continuously, uniformly and uninterruptedly added into the furnace. Along with the rotation of the rotary feeder during feeding, the garbage fed into the furnace can be scattered on any surface on the circular section of the hearth along the radius surface of the hearth. A furnace body (hearth) of the vertical household garbage pyrolysis furnace is divided into a drying layer, a pyrolysis layer, an oxidation combustion layer, a hot slag layer and a cold slag layer from top to bottom. The garbage entering the furnace moves slowly from top to bottom, the primary fan sends primary air into the ash hopper at the bottommost part of the hearth and then enters the oxidation combustion layer from bottom to top, high-temperature mixed flue gas generated by combustion continuously rises to the pyrolysis layer and the drying layer of the hearth to form convection with the garbage from top to bottom, and water in the garbage entering the furnace is evaporated. When the temperature rises to over 600 ℃, a large amount of organic matters in the garbage start to be pyrolyzed and gasified into CO and H2、CmHnAnd the combustible mixed flue gas rises to enter a secondary combustion chamber for combustion. The residual carbon after pyrolysis and gasification of the garbage enters an oxidation combustion layer, and is violently combusted under the action of primary air to release a large amount of heat, and the temperature can reach about 800 ℃ during combustion. The residual high-temperature residue after combustion continuously moves downwards and is cooled by air from bottom to top, the heat carried by the residue is absorbed by the air to preheat the air, and the cooled residue is discharged into a conical ash hopper below the grate under the action of a slag discharging device, then falls into a screw conveyor below the ash hopper and is discharged through the screw conveyor. At present, most of the domestic garbage pyrolysis gasification furnaces of the garbage incineration power plants are forced to be shut down due to coking and dust deposition when the domestic garbage pyrolysis gasification furnaces operate for less than 6 months.
The ash slag generated in the vertical garbage pyrolysis gasification furnace of some manufacturers is crushed by mechanical extrusion of a fire grate, the coking residue generated by burning is crushed into blocks with the diameter of less than 150mm by extrusion of a rotary fire grate and is discharged to the bottom of the furnace, and then the blocks are discharged by a wet type slag discharging machine. The structure has the advantages that the broken slag is extruded in the high-temperature hearth, the grate is quickly worn, refractory bricks in the furnace are quickly worn, and the service life of the grate is short. The furnace grate comprises a grate, a slag discharging port, a discharging port and a discharging port. Therefore, the unique slag discharging device of the novel vertical household garbage pyrolysis gasification furnace is invented, the slag discharging device does not need to crush the slag in the furnace, the slag is directly discharged into the ash bucket, and the problems of coking and ash deposition to block the fire grate are avoided.
