Description

Multi-roller secondary combustion chamber of domestic garbage pyrolysis gas device

Technical Field

The utility model relates to a refuse treatment equipment technical field, concretely relates to multi-roll formula domestic waste pyrolysis gas device postcombustion chamber.

Background

The household garbage pyrolysis gasification device is a device for treating household garbage by utilizing high-temperature oxidation and burning the household garbage at high temperature to convert combustible waste in the household garbage into carbon dioxide, water and the like. The ash and slag after incineration are only less than 20% of the original volume of the domestic garbage, thereby greatly reducing the amount of solid waste. When pyrolysis gasification is carried out, sufficient combustion and further flue gas treatment must be considered to reduce the harmful substances generated by incineration from entering the atmosphere, and meanwhile, effective resource utilization of the heat generated by incineration is also considered to improve the energy-saving and environment-friendly performance of the system.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems and providing a multi-roller type domestic garbage pyrolysis gas device secondary combustion chamber, which realizes harmless emission after the flue gas is fully combusted.

The utility model adopts the technical proposal that:

the secondary combustion chamber is characterized by comprising a first combustion chamber, a second combustion chamber and a third combustion chamber, wherein a flue gas inlet and a flue gas channel are formed in the first combustion chamber, the second combustion chamber is internally provided with a flue gas channel, the flue gas channel of the first combustion chamber is communicated to the second combustion chamber, a plurality of oxygen supply holes are formed in the first combustion chamber and the second combustion chamber, the flue gas channel of the second combustion chamber is communicated to the third combustion chamber, the third combustion chamber is internally provided with a flue gas channel and a grid plate, and a settling chamber is arranged below each of the three combustion chambers.

Further, the flue gas channels and the oxygen supply holes in the first combustion cavity and the second combustion cavity are arranged in a staggered mode.

Further, the grid plate is located at the bottom of the back face of the third combustion chamber.

Further, the three combustion chambers are arranged from low to high, the first combustion chamber is lowest in position, and the third combustion chamber is highest in position.

The utility model has the advantages that:

(1) the three combustion chambers are respectively combusted, so that the flue gas is combusted more thoroughly;

(2) the flue gas is filtered and discharged, and the heat loss is reduced.

Detailed Description

The following describes in detail the specific embodiment of the secondary combustion chamber of the multi-roller domestic garbage pyrolysis gas device of the present invention with reference to the accompanying drawings.

Referring to the attached figure 1, the secondary combustion chamber of the multi-roller domestic garbage pyrolysis gas device comprises a first combustion chamber 1, a second combustion chamber 2 and a third combustion chamber 3.

Set up flue gas inlet 4 and flue gas passageway 5 in the first combustion chamber 1, all be equipped with flue gas passageway 5 in the second combustion chamber 2, the flue gas passageway 5 of first combustion chamber 1 communicates to second combustion chamber 2, sets up a plurality of oxygen feed holes 6 in first combustion chamber 1 and the second combustion chamber 2, and flue gas passageway 5 and the oxygen feed hole 6 in first combustion chamber 1 and the second combustion chamber 2 are crisscross arranges.

The flue gas channel 5 of the second combustion cavity 2 is communicated to the third combustion cavity 3, the flue gas channel 5 and the grid plate 8 are arranged in the third combustion cavity 3, and the grid plate 8 is positioned at the bottom of the back of the third combustion cavity 3.

And settling chambers 7 are arranged below the three combustion chambers. The three combustion chambers are arranged from low to high, the first combustion chamber 1 is the lowest, and the third combustion chamber 3 is the highest. So as to facilitate the flow of the flue gas and the mixing with the oxygen.

The flue gas that domestic waste produced after the burning gets into first combustion chamber 1 through the flue gas inlet 4 of first combustion chamber 1, and the confession oxygen hole 6 of first combustion chamber 1 supplies oxygen or air, burns after mixing with the flue gas, and the ashes that the burning produced fall into settling chamber 7. The flue gas after burning enters the second combustion chamber 2 from the flue gas channel 5 of the first combustion chamber 1, and similarly, the flue gas entering the second combustion chamber 2 is mixed with the oxygen entering the second combustion chamber 2 from the oxygen supply hole 6, and then secondary combustion is carried out, and the furnace ash generated by combustion falls into the settling chamber 7. The flue gas after burning gets into third combustion chamber 3, discharges through the flue gas passageway 5 of third combustion chamber 3, because grid plate 8 on the flue gas passageway 5 of third combustion chamber 3 filters the dust in the flue gas. The ashes in the third combustion chamber 3 also fall into its settling chamber 7.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
