Description

A kind of cremation machine flue gas processing equipment and method

technical field

The invention relates to the technical field of cremation flue gas treatment, in particular to a cremation machine flue gas treatment device and method.

Background technique

Dioxins are usually composed of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and coplanar polychlorinated biphenyls. These substances are stable and difficult to degrade in the natural environment, so they are listed in the "Stockholm The Convention is listed as one of the first twelve pollutants to be controlled. However, dioxin is usually a by-product of industrial production, such as incineration of waste gas, smelting of organic metals, or unintentional production in chemical production. It involves many industries, and there is a long way to go to control it.

Current research shows that the current dioxin formation temperature is mainly in the range of 250-850 ° C. Usually, the most suitable condition for dioxin production is that it has not been fully burned, and some of it is produced in the flue gas that is slowly cooled after full combustion. There are mainly the following methods to control the formation of dioxins:

(1) The temperature of the flue gas in the secondary combustion chamber is above 850°C, the residence time is greater than 2 seconds, and the fuel and oxygen are fully mixed to ensure that the combustion can fully reduce the formation of dioxins.

(2) The flue gas drops from 850°C to 200°C in the quench tower, crossing the temperature range where dioxins are formed.

At present, most cremation furnaces cannot achieve the best working environment and temperature due to production conditions and economic reasons, and the extreme cooling speed of the flue gas generated by cremation cannot reduce the temperature of the flue gas from 850°C to 200°C in time. Therefore, the domestic cremation industry is still facing the situation of exceeding the standard of dioxins in the production exhaust. At present, the control method of dioxin in the production tail gas is mainly to improve the filtration accuracy of the bag filter to improve the effective interception of particulate matter. Dioxin will be attached to the particulate matter and be blocked to remove dioxin. This process method The removal efficiency of dioxins is limited, and some effects can only reach a removal rate of about 25%. Some processes use activated carbon adsorption to remove dioxins, and the removal efficiency can reach 85%. However, the use of activated carbon adsorption process greatly increases the maintenance workload. However, the polluted activated carbon is still a solid waste, and it still needs to be incinerated, and the accumulated consumption of activated carbon and the disposal cost of activated carbon in the later stage are very high, and the economic applicability is very low.
