Embodiment 1

[0020] Example 1: (1), domestic garbage is fed into the inner furnace body through the feed channel and through holes, the combustion chamber works, and the air source fills the inner furnace body with air with a flow rate of 4L / min, and the inner furnace body is heated at 10r / min The speed of min is rotated for 5 min; (2), the inner furnace body is rotated at a speed of 6r / min, and the lime water with a concentration of 0.12mol / L is injected into the sprinkler head, and the sprinkler head is opened to spray the lime water downward; ( 3) When the domestic waste is burned, the combustion chamber stops working, and the inner furnace body is rotated so that the three through holes are respectively connected with the feeding channel, the air intake channel and the exhaust port one by one.

Embodiment 2

[0021] Example 2: (1) Household garbage is fed into the inner furnace body through the feed channel and through holes, the combustion chamber works, the gas source fills the inner furnace body with air with a flow rate of 6L / min, and the inner furnace body is heated at 15r / min The speed of min is rotated for 6 min; (2), the inner furnace body is rotated at a speed of 7r / min, and the lime water with a concentration of 0.14mol / L is injected into the sprinkler head, and the sprinkler head is opened to spray the lime water downward; ( 3) When the domestic waste is burned, the combustion chamber stops working, and the inner furnace body is rotated so that the three through holes are respectively connected with the feeding channel, the air intake channel and the exhaust port one by one.

Embodiment 3

[0022] Example 3: (1), domestic garbage is sent into the inner furnace body through the feed channel and through holes, the combustion chamber is working, the gas source is filled with air with a flow rate of 8L / min into the inner furnace body, and the inner furnace body is fed at a rate of 20r / min. The speed of min rotates for 7 minutes; (2), the inner furnace body rotates at a speed of 9r / min, injects lime water with a concentration of 0.16mol / L into the sprinkler head, and the sprinkler head opens to spray lime water downward; ( 3) When the domestic waste is burned, the combustion chamber stops working, and the inner furnace body is rotated so that the three through holes are respectively connected with the feeding channel, the air intake channel and the exhaust port one by one.

[0023] The present invention controls the inner furnace body to start rotating at a speed of 10-20r / min, and fills the inner furnace body with air with a flow rate of 4-8L / min to quickly ignite dom...

Abstract

The invention discloses a smoldering type household waste incineration treatment device and a use method thereof. The smoldering type household waste incineration treatment device comprises an incinerator and a tail gas treatment device communicating with the incinerator. The smoldering type household waste incineration treatment device has the beneficial effects that by the matching of an inner incinerator body and an outer incinerator body, intermittent oxygen supply is adopted, and gas for sustained combustion can be accessed to the inner incinerator body simply when a through hole communicates with a feeding channel, an air inlet channel and a smoke vent, so that the combustion of the inner incinerator body is kept in a smothering stage, fuel consumption and the content of nitrogen oxide in flue gas are reduced; the inner incinerator body, at a set rotational speed, allows air to be fully contacted and mixed with waste and allows the air to be fully contacted and mixed with the flue gas and the disturbance is full, so that noxious substances are subjected to oxygenolysis in a short time; large grain impurities and an irritation smell in the exhausted flue gas are filtered through a filter screen and a deodorization layer, and finally the raising flue gas is subjected to spraying desulfurization by employing a spray head, thus dedusting, deodorization and desulfurization treatment on the flue gas are completed.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a domestic garbage incinerator and a method for using the same. Background technique [0002] Garbage incinerator is a device for incinerating domestic garbage. Domestic garbage is burned in the furnace and becomes waste gas, which enters the secondary combustion chamber, burns completely under the forced combustion of the burner, and then enters the spray dust collector. After dust removal, it is discharged through the chimney. into the atmosphere. As an incineration system, the most important indicator is the destruction rate of harmful substances in the incineration device. The following factors affect the destruction rate: incineration temperature, residence time, disturbance and air excess coefficient. 1 Incineration temperature: Incineration temperature refers to the temperature at which harmful components in waste are oxidized, decomposed, and destroyed at high temperatur...
