Flue gas purification dust removal system for environmentally-friendly cremation machine

Abstract

The invention discloses a flue gas purification dust removal system for an environmentally-friendly cremation machine, which comprises a secondary flue gas combustion chamber, a heat exchanger, a desulfurization and dust removal tower and an activated carbon dust adsorption tower, flue gas discharged by the secondary flue gas combustion chamber passes through the heat exchanger and enters into the desulfurization and dust removal tower; the desulfurization and dust removal tower adopts an adjustable dynamic multiple venture working mode; and an anion high pressure electrostatic dust catcher is arranged between the desulfurization and dust removal tower and the activated carbon dust adsorption tower and used for firstly opening exhaust gas factors into fragments after the exhaust gas factors are bombarded by high-energy electrons to achieve the effect of dust removal. As the desulfurization and dust removal tower is improved, the problems of scaling and blockage existing in the equipment are solved, the desulfurization efficiency can be up to above 95 percent at maximum, the dust removal efficiency is above 99 percent, and the adaptive dynamic range is above 45 percent. The flue gas purification dust removal system has the characteristics of small floor area, low running cost, wide application scope, simple structure and fewer easily damaged parts.

Description

technical field [0001] The invention relates to a cremation machine, in particular to a cremation machine flue gas purification and dust removal system. 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 included "...

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

[0003] Among the existing flue gas purification treatment equipment, the biggest disadvantage of the technical solution is the use of a bag filter, so in the process of work, the bag filter is easy to stick to oil, resulting in blockage, which not only greatly reduces the dust removal effect, but also affect the normal work

In addition, there is no maintenance inspection port on the traditional desulfurization and dust removal tower, so it is extremely inconvenient to repair and maintain the various components in the tower
