Smoldering type household waste incineration treatment device and use method thereof

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...

AI Technical Summary

Problems solved by technology

The oxygen concentration in the furnace, the degree of mixing of materials and flue gas with oxygen seriously affect the burning speed and burn-out rate of materials. Too much excess air can increase the combustion speed and burn rate, but it will increase the amount of auxiliary fuel, blowing air, induced air and the scale of exhaust gas treatment, which is uneconomical. Conversely, if the excess air is too small, the combustion will be incomplete, and even black smoke will be generated, and the decomposition of harmful substances will not be complete. Generally, the excess air is 30-50% of the theoretical air value

[0003] Existing domestic waste incinerators are often incinerated with open flames, the incineration temperature is high, the fuel consumption is increased, and the content of nitrogen oxides in the flue gas is increased; the disturbance is insufficient; the excess air volume cannot be accurately controlled, and often cannot reach Requirement index of theoretical air value
