The five-part structure of the incineration system of the domestic waste incinerator

Many municipal landfills have reached their disposal limits, and the public is increasingly concerned about the environmental problems caused by improper waste disposal methods. The use of waste incinerators has become a better choice for garbage disposal. While domestic waste incinerators cannot completely replace landfills, they can reduce the number of landfills. Waste incinerator disposes of garbage. The incinerator incineration system includes: feeding, combustion support system, incineration system, dust collection system, and electrical control system.

1. Feeding method

Choose a reasonable feeding method according to different designs.

2. Combustion support system

The main equipment is a gas burner.

The role of the combustion system is to ignite the furnace and incinerate auxiliary materials. By mixing natural gas fuel and air in the burner head, better combustion parameters can be obtained by adjusting the combustion air and burner head. The exhaust gas is recycled at the head of the burner, which can reduce the emission of pollutants to a greater extent, especially the emission of nitrogen oxides, with low emissions, and has the functions of automatic management of combustion program, flame detection, automatic judgment, and fault prompt. The burner has the functions of automatic ignition, fire extinguishing protection, fault alarm, high flame intensity, stable combustion, good safety, and large power adjustment. Flame size, built-in pressure regulating valve to ensure the stability of outlet pressure, can also adjust the supply pressure, adjust the size of the gas volume.

3. Incineration system

The main body is the furnace body.

The furnace body is made of refractory materials, thermal insulation materials, and thermal insulation materials in the upper chamber of the furnace grate, wrapped with steel plates to prevent flue gas leakage, the surface temperature of the furnace body is less than 50%, the furnace body side is equipped with a maintenance door, the furnace body side is equipped with an auxiliary ignition burner is also on the side, and the furnace body is equipped with an operating platform.

4. Dust removal system

The dust collection system is mainly composed of three parts: dust collection cylinder, inverted cone and exhaust pipe, and the function of the dust collection system is to collect dust particles in the flue gas produced by the incinerator. Spray the material, which is convenient for centralized cleaning, and can reduce air pollution and purify the environment.

The working principle of the dust removal system: the dust particles in the flue gas produced by the incineration materials reach the cyclone dust collector under the strong suction of the induced draft fan, which is a device used to separate dust particles from the air stream. Centrifugal descent principle, the upper part of the cyclone dust collector is conical. When the dust gas enters from the tangential direction of the intake pipe on the upper side of the cylinder, it acquires a counter-rotation. After the dust is separated, it is discharged from the exhaust pipe at the top of the cylinder. Dust particles fall from the bottom of the conical into the dust canister.

5. Electronic control system

The power distribution cabinet includes: the main power supply of the whole set of equipment, the power distribution control switch of a single device, the start and stop control of the whole set of equipment and a single device, the protection circuit, the alarm and other operation panels.
