Wet quenching flue gas dust removal and white smoke removal multi-purification treatment device and method

Abstract

The invention relates to a wet quenching flue gas dust removal and white smoke removal multi-purification treatment device and method. The device comprises a partition unit, a cooling and humidifyingunit, a cyclone dust removal unit, a wet electric dust removal unit, a fan, a white smoke removal unit, an air suppression unit and a dust catching unit. The device has the beneficial effects that multiple purification treatments of dust removal and white smoke removal of wet quenching flue gas can be realized through wind suppression and dust catching, secondary dust removal and white smoke removal heat exchange, so that the pollution and corrosion to the surrounding environment and buildings are reduced, the environment is protected, the influence on the body health, production and life of surrounding residents and workers in the field is eliminated, and has the characteristics of low investment cost, simple structure, convenience in maintenance, good cooling effect, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of coke oven flue gas purification, in particular to a multiple purification treatment device and method for wet coke quenching flue gas dedusting and dewhitening. Background technique [0002] The commonly used methods of coke quenching in coking enterprises are mainly divided into wet coke quenching and dry coke quenching. Dry coke quenching can not only recover the high-temperature sensible heat of coke, but also has less pollution to the environment. It is a coke quenching method encouraged by the state, but the high investment limits its popularization, and due to coal source conditions, product characteristics requirements, etc. The reason is that some coking plants are not suitable for dry coke quenching, and can only use wet coke quenching.

Problems solved by technology

Dry coke quenching can not only recover the high-temperature sensible heat of coke, but also has less pollution to the environment. It is a coke quenching method encouraged by the state, but the high investment limits its popularization, and due to coal source conditions, product characteristics requirements, etc. The reason is that some coking plants are not suitable for dry coke quenching, and can only use wet coke quenching

[0003] At present, the conventional wet coke quenching is to pour industrial water directly on the high temperature coke to cool down the coke by rapid spraying, which has the characteristics of simple process and low investment, but it cannot recover the high temperature sensible heat of coke, and A large amount of water vapor will be generated, and the water vapor mixed with a large amount of coke powder particles will spread outward from the top of the coke quenching tower, which will not only cause different degrees of pollution and corrosion to the surrounding atmospheric environment, structures, plants, and residential facilities. It also has a serious impact on the health and production and life of the surrounding residents and the personnel in the field.
