Description
Technical Field
The invention belongs to the technical field of flue gas dust removal and purification, and particularly relates to skid-mounted purification equipment and method for organic solid waste gasification-incineration flue gas.
Background
With the rapid development of the economic society of China, the organic solid waste yield of China is gradually increased. The gasification-incineration technology of the organic solid waste is a novel heat treatment technology, and can realize the reduction, recycling and harmless treatment of the organic solid waste. The gasification-incineration technology refers to the process that the pretreated organic solid waste is dried, pyrolyzed, oxidized and reduced in a pyrolysis gasification furnace, the generated synthesis gas or combustible gas is introduced into a combustion chamber for combustion, and the generated heat is subjected to thermoelectric combination through a waste heat boiler or an internal combustion engine. Compared with the traditional incineration technology, the traditional incineration technology is easy to cause the problem of secondary pollution represented by dioxin due to insufficient reaction, and the organic solid waste gasification-incineration technology can reduce the generation of pollutants such as dioxin in principle by controlling the reaction conditions such as oxygen deficiency and the like, and has the advantages of low smoke emission, high energy utilization rate and the like.
The components of the flue gas generated in the thermochemical treatment process of the organic solid waste are very complex, and secondary pollutants such as dust particles, acid gases, heavy metals, organic pollutants and the like are included. Therefore, when organic solid waste is treated by adopting the gasification-incineration technology, the organic solid waste must be subjected to the treatment of dust removal and purification of flue gas so as to reach the emission standard and avoid secondary pollution. Unlike the flue gas from direct incineration, the gasification-incineration flue gas has relatively low content of pollutants such as sulfur dioxide and nitrogen oxides, because during the pyrolysis and gasification of organic solid wastes, nitrogen and sulfur elements are rarely oxidized and remain in solid ash and slag, and do not enter a secondary combustion chamber along with volatile matters.
Most of the existing flue gas dust removal and purification equipment aims at the traditional incineration technology, and few treatment equipment and methods aim at the organic solid waste gasification technology, and the existing technology and equipment have the problems of low flue gas treatment efficiency and incomplete purification effect.
