Wherein, be provided with two arc duckbilled air supply boards in every group air supply unit, two arc duckbilled air supply boards set up side by side, and the main air supply pipe is connected with two air-movers through T type three-way pipe, and two air-movers are connected with two arc duckbilled air supply boards correspondence. And the air distribution uniformity, the air supply efficiency and the utilization rate are improved.
Wherein, the furnace bottom is designed as a 38-degree inclined slope. So that the garbage can naturally roll and slide down in the combustion process. Mechanical stirring is not needed, no electric control is needed, the failure rate in the furnace is reduced, and the operation cost is saved.
Wherein, the main air supply pipe of each group of air supply units adopts an independent air source.
Wherein, the main air supply pipe of each group of air supply units shares an air source.
The air source end of the main air supply pipe is provided with a circulating fan, the air source is oxygen-enriched furnace body tail gas, and the furnace body tail gas is in sealing connection with the circulating fan through a pipeline after oxygen-enriched treatment. The high-temperature flue gas is recycled, and the combustible substances and harmful substances of the high-temperature flue gas can be decomposed again while the heat of the furnace body is improved, so that the energy recycling is realized.
Wherein, a plurality of air supply tubules are arranged in the arc duckbill air supply plate, and each air supply tubule extends to the flat air port from the blower in order. The air blower can evenly distribute air to the furnace body.
In summary, the air supply system of the household garbage pyrolysis gasification furnace provided by the invention realizes smooth, uniform, comfortable and continuous air supply into the furnace body through the arc duckbill air supply plate, so that the combustion is sufficient and stable, and meanwhile, under the condition of ensuring the normal combustion in the furnace, some tail gas, odor and the like can be selected as air sources, thereby being beneficial to further decomposition treatment of waste gas and realizing energy recycling.
