Domestic waste incinerator is an important equipment for processing domestic waste, and there are many types of it, which can be divided into different types according to different classification standards. According to whether the furnace is divided into grate type incinerator and hearth type incinerator; According to the combustion method, it can be divided into room-fired incinerators, cyclone incinerators and fluidized incinerators. List of high-quality authors
1. Grate type incinerator.
Grate type incinerators are one of the most common types of waste incinerators, with an inclined grate at the bottom of the hearth that feeds the waste into the combustion chamber for combustion as it moves over the grate. Grate type incinerators can be divided into two types: mechanical grates and natural ventilation grates. The grate of a mechanical grate incinerator can control the degree of burning of the waste by adjusting the speed of movement and combustion of the garbage. The natural draft grate type incinerator has a simple grate and is suitable for small waste treatment plants.
2. Hearth-type incinerator.
A hearth-bed incinerator is equipped with a hearth bed at the bottom of the furnace, and garbage is burned on the hearth. According to the different combustion methods, hearth bed incinerators can be divided into fixed bed incinerators and fluidized bed incinerators. The hearth of a fixed-bed incinerator is stationary, and the garbage enters from the inlet in the upper part of the hearth, falls on the hearth and moves downwards while being burned. The bottom of the hearth of the fluidized bed incinerator is equipped with an air distribution plate, which fluidizes the garbage particles through the air and makes them suspend for combustion.
3. Room-fired incinerator.
A room-fired incinerator burns garbage in a closed combustion chamber without contact with the outside world. Room-fired incinerators have a high combustion efficiency, but they need to strictly control the feed and air flow to maintain a stable combustion state.
Fourth, cyclone incinerator.
Cyclone incinerators burn garbage by throwing garbage into the furnace chamber by rotating air at high speed. The structure of cyclone incinerator is simple, but the combustion efficiency is low, and it is easy to produce secondary pollution.
5. Fluidized incinerator.
The fluidized incinerator is to suspend the garbage particles in the gas stream for combustion, and the air flow velocity is high, so that the garbage particles are suspended and burned evenly. Fluidized incinerators have a high combustion efficiency and are suitable for processing large amounts of waste.
The above are the common types of domestic waste incinerators, different types of incinerators have their own advantages and disadvantages, and the appropriate treatment method should be selected according to the actual situation. At the same time, in order to reduce secondary pollution and protect the environment, clean energy and waste utilization technologies should be actively promoted to improve the efficiency and quality of garbage disposal.
