Abstract

The invention belongs to the technical field of high-temperature gas filtering equipment, and particularly relates to a box-type high-temperature gas filter which comprises a filter shell and a box-type honeycomb filter unit sealed in the filter shell. According to the box-type high-temperature gas filter disclosed by the invention, the box-type honeycomb filter unit is modularly designed, the structural design is unique, the filter efficiency is high, and when the gas volume is very high, a plurality of box bodies in the same filter shell can be conveniently formed through expansion to operate at the same time; honeycomb type filter elements, an upper cover plate and a lower cover plate in the box type honeycomb filter unit are convenient to disassemble and replace, so that the same filter can be used for filtering high-temperature gas under various working conditions; the box-type honeycomb filter unit structure is cubic and is simple in structure, low in cost, easy to manufacture and convenient to mount, dismount and maintain; the filter elements are small in size, the occupied area of the container is reduced, the space utilization rate is high, and the filter is convenient to transport and store; the blow-back efficiency is high, and the running resistance is small; and dust bridging is avoided through inner side filtration.

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 box-type high-temperature gas filter with a honeycomb filter element. Background technique

[0002] Membrane filter has high filtration precision, relatively stable particle size control, and backwashing is easy to restore performance. It is widely used in various industries such as coal gasification, petroleum catalysis, biomass gasification, waste incineration, pyrolysis and metallurgy. High temperature filter element There are mainly two types of porous ceramic materials and porous metal materials. The structure of high temperature filter elements can be divided into test tube type and honeycomb type. The core component of the filter is the filter element. The structure and size of the filter element determine the filter structure size and filtration efficiency. The development of a high-effic...

Examples

Embodiment 1

[0042] Such as Figure 1 to Figure 3 As shown, the box-type high-temperature gas filter includes a filter housing and a box-type honeycomb filter unit sealed in the filter housing. In this embodiment, there is only one box-type honeycomb filter unit in the filter housing. In actual production, according to Multiple box-type honeycomb filter units can be set up if required, among which:

[0043] The cross section of the filter housing is circular. The filter housing is divided into an upper housing 2 and a lower housing 3. The upper housing 2 and the lower housing 3 are sealed and connected by flanges. The upper housing 2 is provided with an air outlet directly above the top. 7. An air inlet 10 is provided on the side of the bottom of the lower shell 3, and a slag discharge port 11 is provided directly below the bottom of the lower shell 3; at the same time, the blowback pipe 8 is welded on the top of the upper shell 2, such as figure 2 As shown, four blowback pipes 8 are pro...
