Brazed plate heat exchanger is one of the high efficiency and energy saving heat transfer equipment for heating and cooling. It has been widely used in metallurgy, petroleum, chemical industry, machinery, electric power, medicine, food, textile, paper making, shipbuilding and other industrial fields. It is widely used, mainly because of its performance characteristics and advantages, mainly including:
1, Smaller volume, more compact structure;
2, High temperature resistance, high pressure resistance, high insulation coefficient;
3, High heat exchange efficiency, long service cycle;
4, Use less water, save energy;
5, Not easy to scale, easy to maintain.
Brazed plate heat exchanger has many advantages and characteristics, can play a good role in different industrial fields, is a relatively ideal heat transfer equipment.The Brazed plate heat exchanger, assembled with two end plates and connections, is vacuum brazed at extremely high temperatures providing a permanently sealed heat exchanger.
The final result is a strong and compact plate heat exchanger with extremely high heat transmissions. The high heat transmission comes from the main pattern which is designed to create turbulent flow.
Brazed plate heat exchangers - specific steps for cleaning scale
1) Washing: before pickling, the heat exchanger is first washed open, so that there is no mud, scale and other impurities in the heat exchanger, which can not only improve the effect of pickling, but also reduce the acid consumption of pickling.
2) Pour the cleaning liquid into the cleaning equipment, and then inject it into the heat exchanger.
3) pickling: the heat exchanger filled with acid solution is statically soaked for 2h, and then the continuous dynamic cycle is 3 ~ 4h, during which the positive and negative alternating cleaning is carried out every 0.5h. After pickling, if the pH value of the acid is greater than 2, the acid can be reused, otherwise, the acid washing solution should be diluted and neutralized and removed.
4) alkali washing: after the end of pickling, NaOH,Na3PO4, softened water is prepared in a certain proportion, and the heat exchanger is alkali washed by dynamic cycle to achieve acid-base neutralization, so that the heat exchanger plate is no longer corroded.
5) Water washing: after alkali washing, wash the heat exchanger repeatedly with clean softened water for 0.5h, and rinse the residue in the heat exchanger thoroughly.
6) Record: In the cleaning process, the time of each step should be strictly recorded to check the cleaning effect.
