Optimize the layout structure of filter element:

Reasonable filter clearance ensures no accumulation of materials and no bridging, and can realize rapid disassembly, installation, replacement and maintenance of filter elements;

Optimize the inner parts of the shell:

Through the structure to ensure the level gauge detection channel and manhole maintenance position, the equipment installation and maintenance are more convenient and quick, and the maintenance is extremely difficult; Eccentric variable diameter butt welding is selected for winding pipe to ensure welding effect and facilitate pickling.
