Modular high-temperature gas filter

Abstract

The invention belongs to the technical field of high-temperature gas filtering equipment, and relates to a modular high-temperature gas filter. The filter comprises a filter shell, a plurality of filter modules sealed in the filter shell, a back-flushing cleaning system and a partition plate, the plurality of filter modules are connected in series in the vertical direction in the filter shell to form filter units, the plurality of filter units are arranged in parallel, and the tops of the filter units are fixedly connected to the partition plate. Each filter module of the modular high-temperature gas filter is provided with a plurality of filtering elements, so that the modular high-temperature gas filter is large in filtering area and high in efficiency, achieves miniaturization and standardization of equipment, reduces occupied area, is easy for large-scale production, is convenient to mount and maintain, can be assembled according to actual production requirements, reduces equipment cost, and is wide in application range. Due to the unique design that the pipelines and the filter module structures of the back-flushing cleaning system are skillfully inserted, the space utilization rate and functions are maximized, and the filter is compact in overall structure, small in overall thermal stress, good in structural strength and long in service life.

Description

technical field [0001] The invention belongs to the technical field of high-temperature gas filtering equipment, and belongs to environmental protection equipment, in particular to a modular high-temperature gas filter. Background technique [0002] With the development of industrial technology and the improvement of environmental protection requirements, high-temperature gas-solid separation technology has made important progress. High-temperature dust removal and filtration equipment has been widely used in coal gasification, petroleum catalysis, biomass gasification, waste incineration, pyrolysis and metallurgy, etc. every industry. Membrane filters have high filtration precision, relatively stable particle size control, and easy backwashing to restore performance, and are widely used in the field of high-temperature gas filtration. The core component of the filter is the filter element, but in the prior art, the single-layer filter element filter is the most commonly us...

AI Technical Summary

Problems solved by technology

The core component of the filter is the filter element, but in the prior art, the single-layer filter element filter is the most commonly used arrangement. The open end of the filter element is upward, and the structure is simple, which is suitable for smaller filtration area and processing gas volume. It will inevitably increase the diameter of the filter, increase the cost of production and transportation, and the difficulty of processing technology. The increase in the support stress of the tube sheet is easy to damage, and the uneven flow of internal gas will cause dust bridging phenomenon; the existing multi-layer filter has a complicated structure and various designs. Standardization is not achieved, the scope of application is limited, and the cost of processing and customization is high, which is not conducive to mass production and mass promotion
