The working principle of a tubular heat exchanger

A tubular heat exchanger is a device that separates solid particles and impurities by filtering materials inside the tubes or bundles. Its working principle is based on physical filtration. The following is the working principle of a tubular heat exchanger:

1. Solid particles are intercepted: During the process of fluid passing through pipes or bundles, solid particles, suspended solids, impurities, etc. will be blocked and intercepted by the filter material. These solid particles are relatively large and cannot pass through the pores or surface of the filter material.
2. Clean fluid passing through: After being blocked by filter materials, clean fluid will continue to flow through pipes or bundles towards the outlet of the filter.
3. Fluid entering equipment: The liquid or gas to be filtered enters through the inlet of the equipment, usually through pipes or bundles.
4. Cleaning or replacing filter elements: Over time, the thickening of the solid layer can affect the fluid flow rate and reduce the efficiency of the equipment. Therefore, regular maintenance is essential and can restore the performance of the filter by cleaning or replacing the filter elements.
5. Separate and collect solid particles: Solid particles trapped on the filter material will gradually accumulate, forming a solid layer or filter membrane. This layer can continue to filter until the filter element needs to be cleaned or replaced.

The working principle of a tubular heat exchanger is related to microporous filtration and barrier filtration, and its filtration efficiency depends on the pore size and density of the filter material. Choosing appropriate filter materials and design parameters can meet the precision filtration requirements of different applications.
