At present, the method for dewatering sludge mainly comprises the following steps: natural drying, heat drying, mechanical dehydration and electroosmosis. The electroosmosis dehydration of the sludge is as follows: under the action of the electric field, on one hand, cations adsorbed on the surface of the sludge move to a cathode of the electric field under the action of the electric field, and a large amount of aqueous solution in the sludge moves to the cathode along with the cations; and on the other hand, the phenomenon that part of the fine sludge solid particles with negative charges on the surface move to the anode of the electric field. The vertical voltage drier is a high-dry sludge dewatering device which utilizes the principle of electroosmosis and combines certain mechanical pressure to remove a part of intermittent water and adsorbed water which cannot be removed by mechanical filter pressing in sludge. The equipment can reduce the water content of the residual sludge to below 60 percent.
The filter belt is arranged at the cathode of the electric filter-pressing dehydrator, when the dehydrator operates, sludge particles move after the electrode is electrified, water is discharged through the filter belt to form filtrate, solid sludge is intercepted by the filter belt to form filter cakes, after the dehydrator operates for a period of time, the filter belt can be blocked to different degrees, so that the air permeability of the filter belt is poor, liquid can not be discharged smoothly, the sludge dewatering effect is poor, and the working efficiency of the sludge electric filter-pressing dehydrator is influenced. A filter belt of a sludge voltage filter dehydrator is usually adhered with a large amount of sludge in the sludge treatment process, the existing filter belt cleaning technology is usually directly washed by a large amount of clear water, but the filter belt cleaning technology has the problems of large water consumption, incomplete cleaning and the like, the filter belt loses effectiveness after being used for a period of time, and the filter belt needs to be replaced. The working efficiency of the sludge voltage filter dehydrator is seriously influenced, and a new means is urgently needed to ensure that the filter belt is thoroughly cleaned, the service life of the filter belt is prolonged, and the cost is saved.
