Embodiment Construction
[0018] Such as Figure 1~6 As shown, the filter device of Embodiment 1 of the present invention is used for high-temperature gas filtration. The housing 100 is provided with multiple sets of filter units 200, and a positioning device 500 (specifically, a hole is installed between the housing 100 and the filter unit 200). The first space 300 and the second space 400 are connected and formed. The first space 300 is located below the orifice plate in the housing 100, and the second space 400 is located in the housing 100 above the orifice plate. Each set of filter units Each 200 includes a pipe 210 vertically arranged and a filter 220 made of porous sintered iron-aluminum intermetallic compound arranged at intervals along the length of the pipe 210 and installed on the pipe 210. The upper ends of these pipes 210 are installed on the orifice plate and connected with each other. The second space 400 is connected, and the lower end of the pipe 210 is connected to a pipe end positionin...

The invention discloses a filter device with a novel structure, which is beneficial to increasing the total filtering area of internal filtering elements under unit floor area of the filter device. In addition, the invention discloses filter sheets for the filter device. Each group of filter units of the device comprises a vertical guide pipe and the filter sheets, wherein the filter sheets are arranged on the guide pipe at intervals along the length direction of the guide pipe; one end of the guide pipe is mounted on a filter unit mounting and positioning device and communicated with a second space, and the other end of the guide pipe is a free end or is connected with a pipe end positioning device; an inlet communicated with the inner cavity of the guide pipe is formed in the side wall of the guide pipe; each filter sheet is provided with a filtration part and a connection part; the whole filtration parts are sheet-shaped, and a cavity is formed in each filtration part; each connection part is positioned at one side part of the corresponding filtration part, and the filtration parts are mounted on the side walls of the guide pipes through the connection parts; the outer surfaces of a front panel and a rear panel, playing a main filtering role, on each filtration part are filtration surfaces, and an included angle between each filtration surface and a guide pipe axis is larger than or equal to 0 degree and smaller than or equal to 30 degrees.
Description
Technical field [0001] The invention relates to a filter device and its filter element, in particular to the structure of the filter device and the filter sheet inside. Background technique [0002] The existing gas filter device generally adopts the following structure: the gas filter device includes a housing, an orifice plate installed in the housing, and a filter element installed on the orifice plate (the current filter element uses a cloth bag or filter tube, and the filter tube can be divided into Sintered metal porous material filter tube, sintered ceramic porous material filter tube, organic porous material filter tube), the shell is located above the orifice plate to form a clean air cavity, and the shell is located below the orifice plate to form a raw air cavity. The air inlet communicated with the cavity and the air outlet communicated with the clean air cavity, and the lower part of the shell is convergent to form an ash accumulation and ash discharge part. When in...
