Technical Field
The invention relates to the technical field of flue gas purification treatment, in particular to a high-efficiency flue gas purification treatment system of an incineration system.
Background
Incineration systems can treat waste, pollutants and other harmful substances and convert them into ash and flue gas. The main purpose of the incineration system is to completely decompose the waste by high-temperature combustion, thereby reducing the influence on the environment. Flue gas is one of the gaseous byproducts generated during incineration. The flue gas contains various gases and particulate matter such as carbon dioxide, sulfur dioxide, nitrogen oxides, heavy metals, organics, and the like. These substances can be potentially harmful to the environment and human health and therefore require purification treatments before being discharged.
At present, when the flue gas generated in the incineration process is purified, most of the flue gas is purified by adopting a mode of combining filtering of a filter screen and spraying. But in the purification treatment process, dust particles in the flue gas are easy to adsorb and gradually accumulate and adhere to the surface of the filter screen, so that the filter screen is blocked, the frequency of cleaning or replacing the filter screen is increased, the efficiency of the flue gas purification treatment is seriously influenced, the filter screen is more complicated to disassemble and assemble, and meanwhile, the treatment process of the flue gas is required to be stopped, so that the working efficiency of the flue gas purification treatment is greatly reduced. Accordingly, a person skilled in the art provides an efficient purification treatment system for flue gas of an incineration system, so as to solve the problems set forth in the background art.
