Abstract
The utility model provides a high temperature gas dedusting device which is characterized in that an upper pattern plate and a lower pattern plate divide a tank body into a filter area, a clean area and an ash area. A ceramic film is arranged outside a ceramic film tube, and micropores are arranged on the surface. The ceramic film is further divided into a functional film layer and a supporting film layer. The ceramic film can resist high temperature of 800-1,300 DEG C. Gas containing ash enters the tank body through a gas inlet pipe and enters the filter area through gas distributing holes in the lower pattern plate. The upper part of the ceramic film is connected with a buffer sealing gasket which can not only seal the ceramic film tube, but also buffer local stress caused by pulse. A nozzle is arranged below a pulse tube which provides a pulse gas. The nozzle is used for back-flushing and impacting the filter tube by the pulse gas. A pulse valve is arranged at a pulse tube orifice to generate the pulse gas. Timed back-washing or differential pressure feedback back-washing is adopted according to actual condition. A first inlet is formed in the clean area and a second inlet is formed in the filter area, and the first and second inlets are mainly used for maintaining and installing the inner structure of the filter.
