Novel high-temperature gas filtering device

Abstract

The invention provides a novel high-temperature gas filtering device. A gas inlet and a gas outlet are formed in the top of a shell of the filtering device, an ash outlet is formed in the bottom of the shell, the shell is divided into an upper primary filtering system and a lower secondary filtering system through a partition plate, the upper portions of a plurality of ceramic filter elements of the primary filtering system are fixed to the partition plate through pressing plates, the lower portions of the ceramic filter elements of the primary filtering system are suspended, and dust is vibrated off regularly through a back flushing system; dust vibrated by the back flushing system is collected to a conical area below the shell, and the dust is regularly collected to a dust outlet through a screw blade by a bolt dust removal system at the bottom of the shell to flow out. The novel high-temperature gas filtering device solves the technical problems that traditional high-temperature gas filtering equipment is low in dust removal efficiency, unstable in operation, short in service life of a filter element, large in heat dissipating capacity and free of secondary filtering measures once the filter element is damaged, can efficiently remove most of dust from process gas, has a good heat insulation effect, is efficient in secondary filtering, and can be repeatedly used.

Description

technical field [0001] The invention relates to a novel high-temperature gas filter device, which belongs to the technical field of high-temperature gas-solid separation devices, and in particular relates to a high-temperature gas filter device of a waste acid regeneration device. Background technique [0002] In industries such as petroleum, chemical industry, metallurgy, and electric power, high-temperature dust-containing gases are often produced. In order not to adversely affect subsequent processes and meet environmental protection emission standards, these high-temperature dust-containing gases need to be dedusted. Especially in the waste acid regeneration device, a large amount of dust will be generated after the waste sulfuric acid is incinerated by the combustion furnace, and the dust needs to be cleaned up in time to avoid adverse effects on the subsequent processes and equipment. Since the ash forming temperature is about 480°C, the temperature control requirement...
