The primary combustion chamber, secondary combustion chamber, cyclone dust removal equipment, chimney, flue, pipe system software, high pressure fan, auxiliary pressure fan, primary combustion engine, secondary combustion engine, electrical cabinet, temperature display equipment, detection system, etc.

Combustion production process and brief description:

The waste is put into the primary combustion chamber of the waste incinerator grate by human capital, and the full automatic temperature control is used to open the primary combustion. According to the standard of combustion three T (ambient temperature, duration, vortex), sufficient air is available in the combustion chamber of the incinerator for oxidation, thermal cracking and combustion. The flue gas generated by incineration treatment enters the secondary combustion chamber, and the harmful substances in the flue gas that are not burned out are further destroyed in the secondary combustion chamber. In order to dissolve the unburned chemical substances and realize the discharge regulations, the secondary combustion chamber is equipped with a permission burner for combustion, and a distinctive secondary tunnel ventilation device is equipped to ensure that the flue gas is sufficiently touched with O2 under high temperature, and at the same time to ensure the retention time of the flue gas in the secondary combustion chamber, and adjust the air supply and exhaust volume according to the oxygen content of the flue gas at the inlet and outlet of the secondary combustion chamber. The temperature in the secondary combustion chamber is controlled and the smoke and dust with relatively large particles are removed through the dust removal equipment, so that the high efficiency of incineration treatment and the load of sludge destruction can reach above 99%, so that it can achieve no odor, no bad smell, the actual effect of smoke control, meet the environmental protection standards, and then enter the chimney and exhaust into the air, and the embers generated during combustion are removed manually.

1. Single-pulse throwing garbage incineration grate

Principle: The garbage is sent to the drying bed of the garbage incinerator through the full-automatic feeding module for drying, and then sent to the first stage grate. After continuous high-temperature evaporation and cracking on the garbage incinerator grate, the grate is thrown under the drive of the single-pulse gas power system, and the garbage is gradually thrown into the next stage grate. At this time, macromolecular substances are cracked and other components are burned. In this way, it will enter the slag pit until it is burned out, and then be discharged by the fully automatic slag removal equipment. The combustion gas is injected into the exhaust hole in the grate and mixed with the garbage for combustion, at the same time, the garbage floats in the air. The chemical substances from evaporation and cracking enter the second stage combustion chamber for further cracking and combustion, and the unburned flue gas enters the third stage combustion chamber for combustion; The continuous high temperature flue gas heats the steam according to the heating surface of the boiler, and at the same time, the flue gas is discharged after cooling.

2. Mechanical equipment waste incineration grate

Principle: The garbage is fed into the skewed downward garbage incineration grate (the grate is divided into dry area, burning area and burnout area) according to the dumping, because the overlapping fitness exercise between the grates will promote the garbage to the bottom, so that the garbage will turn around according to each area in the grate (when the garbage enters from one area to another, it will play a big role) until it is exhausted and discharged out of the grate. Combustion gas enters from the bottom of the grate and mixes with garbage; The continuous high temperature flue gas causes hot steam according to the drum of the electric boiler. At the same time, the flue gas is also cooled, and the flue gas is discharged after being processed by the flue gas solution equipment.

3. Fluidized bed waste incineration grate

Principle: The furnace wall is composed of perforated structure distribution plates. A large amount of quartz sand is added to the furnace body. The quartz sand is heated to about 600 ℃, and the warm air above 200 ℃ is blown into the furnace bottom to make the hot sand boil, and then the funds are put into the garbage. The garbage is burned together with hot sand, and the garbage is quickly dry, ignited and burned. The proportion of unburned waste is relatively light. When it is burned again, the proportion of burned waste is relatively large and falls into the bottom of the furnace. After water cooling and heat dissipation, the coarse slag and fine slag are sent to the outside of the plant by a separator, and a small amount of medium-level coal ash and quartz sand are sent back to the furnace for normal use according to the lifting device.

4. Tubular waste incineration grate

Principle: The tubular waste incineration grate shall be arranged along the furnace wall with cooling pipes or refractory insulation materials, and the furnace wall shall be placed horizontally and slightly skewed. According to the continuous operation of the furnace body, make the garbage in the furnace body burn enough, and move towards the furnace wall in an inclined direction until it is burned out and discharged from the furnace wall.
