Several classifications of incinerators

Incinerator is often used in medical and domestic waste, animal harmless treatment of a harmless treatment equipment, the principle is the use of coal, oil, gas and other fuels burning, the object to be treated for high temperature incineration carbonization, in order to achieve the purpose of disinfection. Let's take a look at some categories of incineration!

Gasification pyrolysis incinerator

The gasification pyrolysis incinerator has two incineration chambers, a combustion chamber and a secondary combustion chamber, the shell is processed and welded with steel plates, and the interior is masonry with refractory materials. Each chamber is separated by the furnace wall. In the entire incinerator, the air flow constantly changes the direction of movement in the vertical direction, so that the combustible gas and combustible dust particles coming out of the combustion chamber are fully mixed to completely burn out. The waste is entered by the upper hopper of the incinerator through the chute, the waste is sent into the primary combustion chamber by the pneumatic furnace door, the waste entering the primary combustion chamber is regulated by temperature, heated by the refractory wall or disposable burner, the air in the primary combustion chamber is blown into the bottom, top and front, and the large particles are burned out by the air nozzle installed at the bottom of the furnace before entering the secondary combustion chamber. Two delivery planes at the bottom of the primary combustion chamber automatically rotate the garbage and transport the ash to the ash chamber, where it burns out and enters the ash hopper. After the unburned flue gas is mixed at the inlet of the secondary chamber, it is completely burned out in the secondary chamber, the temperature of the primary chamber is 700℃-800℃, the temperature of the secondary chamber is 900℃-1200℃, and the residence time is more than 2 seconds. Auxiliary burners are installed on the side walls of the primary combustion chamber and the secondary combustion chamber to be used when the incinerator is started and the calorific value of waste is low to maintain the furnace temperature.

Mechanical grate industrial waste incinerator

Operation principle: Waste through the hopper into the skew down grate (grate is divided into dry area, burning area, burning area), due to the interwoven movement between the grate, the waste is pushed down, so that the waste passes through the various areas on the grate (waste from one area into another area, play a big turn over the effect), until the burning out of the furnace. The incineration air enters from the lower grate and mixes with the waste; The high-temperature flue gas generates hot steam through the heating surface of the boiler, and the flue gas is also cooled, and the final flue gas is treated by the flue gas treatment equipment.

Fluidized bed industrial waste incinerator

Operation principle: The furnace body is composed of porous distribution plate, participate in a lot of quartz sand in the furnace, the quartz sand is heated to more than 600 ° C, and the hot air is pumped into the bottom of the furnace above 200 ° C, so that the hot sand is jubilant, and then put into waste. Waste gleams with hot sand, and waste is soon dry, on fire, and incinerated. The proportion of unburned waste is light, continuous jubilant incineration, the proportion of burned waste is larger, and it falls to the bottom of the furnace, and after water cooling, the coarse slag and fine slag are sent to the outside of the plant with the sorting equipment, and a small number of medium slag and quartz sand are sent back to the furnace for continuous use by the improving equipment.

Rotary kiln type incinerator

The kiln body is a horizontal and rotating cylindrical cylinder. The shell is made of sheet roll, lined with refractory material; The axis of the cylinder keeps a certain inclination Angle with the horizontal plane, and the solid and viscous waste move slowly from the kiln head (upper part) to the tail with the rotation of the kiln body. The rotation of the kiln body makes the material fully contact with the combustion-supporting air during the combustion process, completing the whole process of drying, burning and burning. The tail discharges the burning residue. The material that is not completely decomposed will enter the secondary combustion chamber for full combustion. The combustion air is taken from the bin to ensure that the odor of the bin does not leak out. The shell of the kiln body is made of carbon structure steel plate rolled and welded. The refractory material in the kiln is acid-resistant refractory clay brick.
