Technical Field
The invention relates to the technical field related to deacidification equipment, in particular to dry-type deacidification cooling equipment.
Background
In a small-sized flue gas purification system for burning solid wastes, the temperature of flue gas discharged from a burning furnace is very high and is not lower than 850 ℃. In order to create conditions for subsequent purification equipment, high-temperature flue gas is firstly required to be subjected to cooling treatment through a heat exchanger. Secondly, the deacidification of the flue gas is divided into a wet type deacidification and a dry type deacidification, and the wet type deacidification can bring a lot of water vapor to the flue gas, so that the filter bag of the dust remover is easily scrapped due to water bag pasting. Therefore, dry deacidification is often used in flue gas deacidification of small solid waste incineration. However, the dry deacidification equipment does not have an effective cooling effect on the temperature of the flue gas, and the heat exchange capacity of the front-end heat exchanger needs to be increased.
