Ash residue ceramic vacuum-filter system

Abstract

The invention discloses an ash residue ceramic vacuum-filter system. The ash residue ceramic vacuum-filter system comprises a plurality of side filters which are mounted on the side wall of an ash residue bin body and are connected with a main water pipeline on the lower part of the ash residue bin body, a central filter which is mounted on the central part of the ash residue bin body and is connected with a main water pipeline on the lower part of the ash residue bin body, an inflatable sealing ring main body which is mounted on the bottom of the ash residue bin body, a water storage tank which is connected with the main water pipeline, and a vacuum pump which is connected with the water storage tank. The ash residue ceramic vacuum-filter system dehydrates and filters water for recycling,saves water, is low in energy consumption, is low in cost, and is low in operation cost. The ash residue ceramic vacuum-filter system can be widely used for in ash residue dehydrating process of a combustion furnace and a gasification furnace in the coal-fired thermal power industry and the coal chemical industry.

Description

technical field [0001] The invention relates to an ashes and slag ceramic vacuum filter system, which can be widely used in the ash dehydration process of combustion furnaces and gasification furnaces in coal-fired thermal power and coal chemical industries. Background technique [0002] At present, to dehydrate the ash and slag of coal-fired thermal power units and combustion furnaces in the coal chemical industry, equipment systems consisting of vibrating screens, centrifuges, filter presses, and filter cloth vacuum filters are used. The equipment is complex, high in cost, and high in operating costs. The water removal rate in the ash is low, and the filter screen of the equipment is easy to be blocked and damaged, which cannot guarantee safe and normal operation, high energy consumption, and there are ash impurities, which cannot meet the purpose of direct recycling and environmental protection requirements. Contents of the invention [0003] The object of the present i...
