Information

The welded plate and frame heat exchanger belongs to the partition heat exchanger. Its structure is that two flow channels are generated by welding between two adjacent plates, and two media with different temperatures flow through the channels on both sides of the same plate. Each medium channel controls the flow area and flow length according to the partition plate, so that the high temperature medium transfers heat to the low temperature medium through the plates. Comply with the law of conservation of energy, and then complete the purpose of heat exchange.

Correct cleaning method of welded plate and frame heat exchanger
       1. For the plate and frame heat exchanger, the scale can be disassembled and washed. But for the fully welded plate heat exchanger, it cannot be dismantled and can only be cleaned online.
       2. Before cleaning, analyze and test the scale caused by the actual working conditions and water quality properties, and prepare chemicals for cleaning.
       3. The difficulty of cleaning the welded plate and frame heat exchanger is gradually increased with the increase of the thickness of the scale layer or the deposition, so the cleaning interval should not be too long. Corrosion rate and operating cycle are regularly inspected, repaired and cleaned.
       4. Before cleaning, there should be places at both ends of the heat exchanger to facilitate the extraction and replacement of pipelines during cleaning and maintenance. One of the advantages of welded plate and frame heat exchangers over tubular heat exchangers is that not only the heat exchanger itself occupies a small area, but also the space to be reserved during cleaning and maintenance is much smaller than that of tubular heat exchangers. In this way, it will not occupy too many production positions and will not affect the placement of other equipment.

The welded plate and frame heat exchanger is widely used in the heating, preheating and condensation process requirements of chemical plants, crude oil, power engineering, metallurgical industry, steam heating and other industries. Because it is fully welded, it has more advantages than detachable plate heat exchangers under pressure and certain high temperature conditions.
