Description

technical field [0001] The invention relates to a cathode hanging system, in particular to a cathode hanging system for a tension-free device of a wet dust collector, and belongs to the technical field of flue gas treatment at the tail of a power plant boiler. Background technique [0002] Wet dust collector is a new dust removal equipment used to deal with tiny dust and particles. It has been used in the chemical industry to remove acid mist for many years. Its basic working principle is the same as that of dry dust collector. In addition to the hanging system of the insulator box on the top of the conventional dust collector, a tensioning device is generally installed at the lower part of the dust collector. Wet dust collectors for power plant boilers are generally arranged behind wet desulfurization towers to treat wet flue gas after desulfurization. Due to the working environment of wet flue gas, the setting of the tensioning device will increase the risk of condensatio...
