Five types of waste incinerators
Talk about the five types of incinerators
If you don't give up this second, there will be hope in the next second! Persevere and you will succeed! Nowadays, environmental protection is advocated. When human beings continue to use natural resources to create material civilization, a large amount of garbage is also produced. Then, the disposal of garbage has become a major problem in modern society. The evolution of incinerators allows for a more efficient solution to waste recycling. There are the following types of incinerators:
1. Pulse throwing grate incinerator
The garbage is sent to the drying bed of the incinerator through the automatic feeding unit to be dried, and then sent to the first-stage grate, where it is volatilized and cracked at high temperature on the grate. The first stage is thrown into the next stage grate, at this time, the macromolecular substances are cracked and other substances are burned.
2. Mechanical grate incinerator
The garbage enters the inclined downward grate through the feeding hopper (the grate is divided into a drying area, a combustion area, and a burnout area). (When the garbage enters from one area to another, it plays a role of turning over) until it is burned out and discharged from the furnace. The combustion air enters from the lower part of the grate and is mixed with the garbage; the high-temperature flue gas passes through the heating surface of the boiler to generate hot steam, and the flue gas is also cooled, and finally the flue gas is treated by the flue gas treatment device and discharged.
3. Fluidized bed incinerator
The furnace body is composed of a porous distribution plate. A large amount of quartz sand is added into the furnace, and the quartz sand is heated to above 600 ℃, and hot air above 200 ℃ is blown into the bottom of the furnace to boil the hot sand, and then throw in the garbage. The garbage boils with the hot sand, and the garbage is quickly dried, set on fire, and burned. The proportion of unburned garbage is relatively light, and it continues to boil and burn, while the proportion of burned garbage is relatively large and falls to the bottom of the furnace. Quartz sand is sent back to the furnace through the lifting equipment for further use.
4. Rotary incinerator
The rotary incinerator is arranged along the furnace body with cooling water pipes or refractory materials, and the furnace body is placed horizontally and slightly inclined. Through the non-stop operation of the furnace body, the garbage in the furnace body is fully burned, and at the same time, it moves in the direction of the furnace body inclination until it burns out and is discharged from the furnace body.
5. CAO incinerator
The garbage is transported to the storage tank, enters the biochemical treatment tank, and is dehydrated under the action of microorganisms, so that the natural organic matter (kitchen waste, leaves, grass, etc.) is decomposed into powder, and other solids include plastic and rubber. A class of synthetic organic matter and inorganic matter in garbage cannot be decomposed and pulverized.
