Purification treatment device for incineration flue gas

Abstract

The invention discloses a purification treatment device for incineration flue gas. A condensate pipe is arranged in a cold and hot exchanger; a combustor is arranged on a flue gas combustion chamber; the flue gas combustion chamber is provided with an inlet and an outlet; the outlet of the flue gas combustion chamber is connected to the inlet of the cold and hot exchanger through a pipeline; the outlet of the cold and hot exchanger is connected to the inlet of a deacidification system through a pipeline; the outlet of the deacidification system is connected to the inlet of a dry-wet separatorthrough a pipeline; the outlet of the dry-wet separator is connected to the inlet of a mixing chamber through a pipeline; an activated carbon storage tank is arranged on the mixing chamber; the outlet of the mixing chamber is connected to the inlet of a bag-type dust collector through a pipeline; the outlet of the bag-type dust collector is provided with a draught fan; the outlet of a dosing device is connected to the deacidification system through a pipeline; a first outlet of a blowing device is connected to the deacidification system through a pipeline; and a second outlet of the blowing device is connected to the mixing chamber through a pipeline.

Description

technical field [0001] The invention relates to a cremation technology in the funeral industry, in particular to a cremation smoke purification treatment device. Background technique [0002] At present, most of the cremation machines used in my country's funeral industry adopt the direct discharge method to discharge cremation waste gas, and the cremation pollution is very serious. The air pollutants produced by cremation include smoke, carbon monoxide, nitrogen monoxide, nitrogen dioxide, and sulfur dioxide. , hydrogen sulfide, ammonia, mercury and other inorganic pollutants, as well as dioxin-like organic pollutants. If it is not effectively controlled, it will inevitably cause serious air pollution in funeral places and severe damage to the surrounding ecological environment. In 2009, the "National Civil Science and Technology Medium and Long-Term Development Plan (2009-2020)" was released and implemented, which listed funeral technology as a key development field, and i...

AI Technical Summary

Problems solved by technology

The disadvantages of the prior art are: 1. The wet purification system with the water curtain spray device as the main component can only remove soot particles and a small amount of acid gas, and cannot effectively remove dioxin-like organic pollutants

2. The dry purification system with bag filter as the main component has basically no effect on the removal of acid gas pollutants

And because the inlet temperature of the two types of purification devices is low (below about 500°C), this temperature is exactly the temperature required for the resynthesis of dioxin-like substances. Therefore, the dioxin-like substances to be treated or discharged in the future The total amount is too large to effectively purify cremation smoke
