Background
The solid waste is called "misplaced resource", and generally includes waste tires, waste plastics, waste gas biomass, waste fibers and other substances; with the increasing importance of the country on environmental protection, a new process for treating solid waste is produced. The cracking method is a process which is recognized at present and can completely make solid wastes harmless and achieve the maximum resource utilization.
The combustible oil, gas and carbonaceous solid residues can be obtained by a cracking process regardless of waste plastics, waste tires or biomass raw materials. Chinese patent CN02133969.4 proposes a pyrolysis furnace and recovery equipment for harmless treatment of combustible solid waste, which can not only pyrolyze non-degradable plastic products, but also produce charcoal powder, wood tar, wood vinegar liquid and wood gas from disposable directly combustible substances and combustible waste through the recovery equipment, and is suitable for the treatment of combustible solid waste, reaching a daily treatment capacity of 20 tons, and increasing the recovery rate of the product. Chinese patent CN02248929.0 proposes a moving bed cracker for generating combustible gas by gasifying biomass, which comprises a shell, a furnace body, a feeding bin port, a conical air distribution plate, a gas inlet, a gas outlet, an ash discharge port, an air inlet pipeline, a fan, a motor, etc.; the furnace body is internally provided with a catalyst charcoal layer, the middle part is a cracking area, the air inlet pipeline enters the furnace body and then is fixed on the inner wall of the furnace body in a circular shape, the air distribution plate is arranged at the lower part of the charcoal layer and plays the roles of uniformly distributing air and supporting the charcoal layer, and the lowest part is an ash discharge port and a spiral ash discharger. In addition, CN200610029347.4 also relates to a device for converting biomass cracking into energy.
These devices all clearly provide that the cracking furnace type device is inevitably provided with a slag discharge port for discharging solid residues in the cracking products, wherein the solid residues are usually carbon dust, have low particle size and density, are easy to scatter with wind, and toxic and harmful substances such as heavy metal, dioxin and the like are easy to adhere to the surfaces of the solid residues after the dirty materials are cracked, so that in the actual operation process of the equipment, a cover plate is required to be additionally arranged on the equipment for storing slag to prevent the furnace ash from flying to cause secondary pollution to the environment.
However, these slags are typically discharged from the furnace at high temperatures, above 400 ℃, and the cracking furnace is typically restricted from oxygen ingress, but the tap hole is not controlled. This causes that, in actual operation, after the slag is discharged from the slag discharge port, the temperature is still very high, even if the slag is stacked for a long time, the temperature is difficult to reduce, and after encountering air, the slag has the risk of reburning, thereby bringing great potential safety hazard to the cracking production process.
In summary, a special storage device for the slag of the cracking furnace is needed, and in the storage process of the slag, the slag can be prevented from being scattered into the environment along with wind blowing, and can also be rapidly cooled, so that safety accidents caused by the reburning of the slag are prevented.
