Abstract

The invention concerns a system for cleaning electrolytic filtering installations without pressure drop or dismantling of the system. The filtering voltage is maintained at a maximum breakdown-limit value. It consists in equipping each assembly consisting of a tube (4) and a high-voltage electrode (3) with a sound generator (13) arranged at one end to operate it, when the filtering operation is stopped, so as to cause the dust to drop which can then be sucked up by a recovery system consisting of a recovery chamber (14) and an extractor (15). The invention is applicable to all installations involving toxic dust.

Description

technical field

[0001] The present invention relates to the field of industrial installations (equipment) producing toxic dust (dust, dust) or non-dust such as particles (particles) suspended in a fluid. This case is a heat treatment method for hazardous substances such as organic nuclear waste, toxic industrial waste or hazardous raw materials. It also relates to the field of electromagnetic filter devices. Background technique

[0002] In many of the aforementioned devices (apparatus) extremely efficient filtration systems are required in order to intervene in those devices dealing with fluids in which dust or particles are suspended.

[0003] There are many filtration systems, which can be divided into the following three categories: systems using mechanical devices, systems using fluids, and systems using physical phenomena.

[0004] The former employ effective physical and mechanical barriers, such as sleeve filters, bag filters, and particle bed filters, but pressure...
