1、 Technical parameters:

Product Name: Pressure Regulating Station, Pre Module Filter Cartridge

Product specifications: 152 * 1000mm 152 * 736mm

Design pressure: 6.5Mpa

Filtering accuracy: 1-3 μ m

2、 Design proposal

1. Material selection:

Because the filter element is a pressure regulating station and pre module filter element, the metal parts are made of stainless steel with good corrosion resistance, and the filter material is made of imported ultra-fine special glass fiber, which has a large pollutant holding capacity, long service life, good compatibility with various mixed gases, high filtration efficiency, and interception rate of 1-3 μ m impurities is higher than 99.99%. The sealing material is made of ultra-fine fiber compression felt, which has good oil aging resistance.

3. Composition and working principle of filter element

Composed of inner lining skeleton, filter layer, and sealing layer.

3.2 Working principle:

The gas passes through the shell and is filtered through the filter layer to remove solid particles, impurities, aerosols, and other desulfurization impurities. The filtered clean liquid flows out of the inner hole and enters the filter outlet for subsequent system use. Impurities are regularly removed through the filter discharge outlet.

The working principle diagram is as follows:

4. Design and calculation of filter support strength

According to the "Specification for Filtration and Separation Equipment in Gas Pipeline Engineering" and customer requirements, the working pressure of the filter is 4.6Mpa, the initial pressure drop of the filter element is 5Mpa, and the pressure difference when replacing the filter element is 0.6Mpa.
