Plate heat exchanger It is a highly efficient heat exchanger composed of a series of corrugated metal plates. A thin rectangular channel is formed between different plates for heat exchange. Plate heat exchangers are ideal for liquid-liquid and liquid-vapor heat exchange equipment.
Plate heat exchanger It has the characteristics of high heat transfer efficiency, low heat loss, compact structure, light weight, small footprint, wide range of applications, and long service life. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of a tube heat exchanger, the floor area is one-third of that of a tube heat exchanger, and the heat recovery rate can reach 90%.
Plate heat exchanger Maintenance and cleaning steps:
1. Remove the gasket: Carefully remove the gasket from each plate. When removing the rubber gasket, we will take corresponding protective measures to prevent damage to the gasket.
2. Plate cleaning: We put the plates into professional cleaning equipment. The entire cleaning process has a strict control procedure to ensure that the plates are completely clean. We formulate different cleaning plans for different working environments.
3. Color inspection: Using coloring and soaking methods, we will strictly check the cleaned plates to ensure that the plates are consistent with the new plates and are free of cracks, corrosion spots, and other defects.
4. Thoroughly soak the plates with a cleaning agent and then clean with air. After cleaning, the surface of the plate will be as smooth as new.
5. Appearance inspection: Carefully inspect the cleaned plate heat exchanger again, arrange it neatly, and wait for the subsequent process.
6. Install gasket: Regarding the installation of gaskets (adhesive or non-adhesive) after cleaning the plates.
7. Packaging and transportation: Plate heat exchanger Professional packaging materials are used for packaging, and corresponding measures are taken to prevent the plates from being scratched during transportation.
