Description
Technical Field
The invention relates to the technical field of cremation flue gas treatment, in particular to cremation machine flue gas treatment equipment and method.
Background
Dioxins are usually composed of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, coplanar polychlorinated biphenyls, which are stable and difficult to degrade in natural environments, and are therefore listed by the "Sjogren's convention" as one of the twelve first-controlled pollutants. Dioxin is usually produced unintentionally in the incineration of industrial byproducts such as waste gas products, smelting of organic metals or chemical production process, and relates to numerous industries, and the control of the dioxin is far from the control of the dioxin.
The current research shows that the generation temperature of the dioxin is mainly in the range of 250-850 ℃, the optimum generation condition of the dioxin is that the dioxin is not fully combusted, and part of the dioxin is also generated in the flue gas which is slowly cooled after the full combustion, and the method for controlling the generation of the dioxin in the incineration process mainly comprises the following steps:
(1) The temperature of the flue gas in the secondary combustion chamber is above 850 ℃, the residence time is more than 2 seconds, and the fuel and the oxygen are fully mixed to ensure that the generation of dioxin is fully reduced by combustion.
(2) The flue gas is reduced from 850 ℃ to 200 ℃ in the quenching tower and spans the generation temperature interval of dioxin.
At present, most cremation hearths cannot reach the optimal working environment and temperature due to production working conditions and economical reasons, and the extremely cold speed of smoke generated by cremation cannot timely reduce the temperature of the smoke from 850 ℃ to below 200 ℃, so that the domestic cremation industry still faces the condition of exceeding the standard of dioxin in production tail gas. The existing control method for dioxin in production tail gas mainly improves the filtering precision of a bag type dust collector to effectively intercept particulate matters, the dioxin is attached to the particulate matters to be blocked to achieve the purpose of removing the dioxin, the process method has limited dioxin removing efficiency, partial effect can only achieve about 25% of removing rate, the process adopts an activated carbon adsorption method to remove the dioxin, the removing efficiency can reach 85%, but the maintenance workload is greatly increased by using an activated carbon adsorption process, the polluted activated carbon is still solid waste, the polluted activated carbon still needs to be incinerated, and daily accumulated activated carbon consumption and disposal cost of the later activated carbon are very high, so that the economic applicability is very low.
