Description of the working process:
flow of garbage (solid matter):
and (4) smashing the wet garbage and the screened combustible garbage, and then putting the smashed wet garbage and the screened combustible garbage into a putting cabin by taking 120L as a unit. The garbage is quantitatively supplied to the reaction furnace by the rotation of the stirring blades in the charging chamber, but the dry distillation gas from the reaction furnace does not flow into the charging chamber.
On the lower surface of the feeding cabin, a part of water of the garbage is evaporated and dried due to heat transferred from the reaction furnace. After the steam is evaporated, the waste is introduced into a reaction furnace. Therefore, the water vapor generated in the drying process of the garbage can be prevented from reacting with the dry distillation gas to generate tar, and the spontaneous combustion reduction combustion can be realized by using the reaction furnace without auxiliary fuel.
The garbage entering the reaction furnace is horizontally dispersed by the stirring rod which is supplied with air once through the stirring rod in the furnace. The stirring rod and the stirring blade rotate coaxially, and can ensure the stable supply and reduction combustion of the garbage in the reaction furnace.
The garbage entering the reaction furnace is dried by the generated 600-800 ℃ dry distillation gas at the upper part and is subjected to partial combustion and thermal decomposition by primary air preheated by the temperature of 300-500 ℃ in the furnace at the lower part to generate dry distillation gas.
The burning ash powder is reduced through reduction and combustion in the reaction furnace, and harmful heavy metals such as hexavalent chromium and the like are reduced into trivalent chromium and discharged through an ash discharging mechanism.
Gas flow:
the primary air supplied to the reaction furnace is preheated to 300-500 deg.C by the combustion heat in the furnace and the residual heat of ash powder, and in the reducing environment, it makes partial combustion and thermal decomposition reaction with the dry garbage in the furnace to become the dry distillation gas with 600-800 deg.C.
When the reducing gas (H2O, CO2, N2, CO, H2, CH4, etc., and not O2) generated in the reaction furnace passes through the garbage dried layer in the furnace, the entrained ash is removed, and the concentration of coal dust in the dry distillation gas is reduced.
The retort gas is sucked out from the furnace top by an exhaust gas suction device to reduce the pressure in the furnace, and then introduced into a secondary combustion device. In the secondary combustion apparatus, the secondary air and the combustible gas in the dry distillation gas are all combusted, and the generation of odor, CO, dioxin, and the like is suppressed.
Since the secondary combustion apparatus generates harmful components such as NOx when it burns at a high temperature of 900 ℃ or higher, it is necessary to cool the outer wall of the secondary combustion apparatus with air and appropriately control the combustion temperature. The hot air generated at this time can be used for heating houses in winter.
The completely combusted waste gas is exhausted from the chimney through the air suction device by utilizing the Venturi effect, and because the waste gas from the chimney has the characteristics of low self temperature, low concentration of harmful components and the like, and the phenomenon of white frost generated when the exhaust port of the chimney exhausts is avoided, the gas which is more fully combusted in the secondary combustion chamber can be exhausted into the air in a negative pressure rapid cooling state by utilizing the Venturi effect.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
