Household garbage pyrolysis gas carbonization treatment system and process thereof

Abstract

The invention discloses a household garbage pyrolysis gas carbonization treatment system and a process thereof, and relates to the technical field of household garbage treatment, the household garbage pyrolysis gas carbonization treatment system comprises a pyrolysis gas carbonization device, a turning type multi-stage rotational flow oxidation chamber, a reverse type uniform rotational flow purification device, a low-temperature plasma dust removal device and a chimney. The device is scientific in design and reasonable in process, waste gas generated by garbage combustion in the process of preparing a large amount of household garbage can be fully oxidized, decomposed, combusted and completely utilized, combustion tail gas meets the emission standard, the content of sulfur dioxide, nitric oxide, carbon monoxide and nitride in the tail gas can be greatly reduced, and the environment is protected. Secondary generation of dioxin is reduced, and the difficult problem that tail gas reaches the standard in the household garbage gas carbonization process in the prior art and the problem that pipelines in the whole treatment system are blocked by tar in the technical field can be solved.

Description

technical field [0001] The invention relates to the technical field of domestic waste pyrolysis gas carbonization treatment, in particular to a domestic waste pyrolysis gas carbonization treatment system and a process thereof. Background technique [0002] In recent years, with the improvement of people's living standards, the amount of domestic waste is increasing rapidly, and the annual accumulation and storage of waste is very large. If the landfill is used for waste disposal, it will cause huge pollution to land resources and waste Land resources are not conducive to agricultural development. The incineration method can maximize the effective treatment of domestic waste and occupy the least land resources. However, the incinerated waste gas is discharged directly without treatment, which will cause serious air pollution and is not conducive to the protection of the ecological environment. In the existing waste treatment technology, the waste is mainly incinerated by add...

Problems solved by technology

[0003] The object of the present invention is to address the above problems, to provide a domestic waste pyrolysis gas carbonization treatment system and its process, which has a scientific design and a reasonable process, and can fully oxidize, decompose and decompose the waste gas generated during the combustion of a large amount of domestic waste. Combustion is fully utilized, so that the combustion tail gas meets the emission standards, which can greatly reduce the content of sulfur dioxide, nitrogen oxides, carbon monoxide, and nitrogen compounds in the tail gas, reduce the secondary generation of dioxins, and can solve the carbonization of domestic garbage gas in the existing technology Difficult to solve the problem of tail gas compliance in the process and the blockage of tar in the entire treatment system in the technical field
