How to clean corrugated tube volumetric heat exchanger

1： Clean with descaling

Add the configured descaling and cleaning agent into the circulating water of the cleaning tank in proportion for cleaning and descaling. Determine the cleaning cycle time and the amount of agent added according to the amount of scale in the corrugated tube positive displacement heat exchanger. After confirming that all the scales have been cleaned, move to the next cleaning procedure.

2： Clean with clean water

After the cleaning equipment is connected, clean the corrugated tube positive displacement heat exchanger with clean water for about 15 minutes, check the status of the corrugated tube positive displacement heat exchanger system for leakage, and clean the floating rust of the corrugated tube positive displacement heat exchanger

3： Clean with peeling anti-corrosion

Add surface stripping agent and slow-release agent into the circulating water of the cleaning tank of corrugated tube positive displacement heat exchanger in proportion, and conduct circulating cleaning for about 30 minutes to separate the scale of corrugated tube positive displacement heat exchanger from the cleaned parts. At the same time, conduct anti-corrosion treatment on the surface of the object without scale, and prevent the corrosion of the cleaned parts caused by the cleaning agent during descaling cleaning.

4： Treat with passivation coating

Add passivation coating agent to corrugated tube positive displacement heat exchanger, and conduct passivation coating treatment on the cleaning system of corrugated tube positive displacement heat exchanger to prevent corrosion of pipes and components and the generation of new rust.

The corrugated tube positive displacement heat exchanger is a heat exchanger that uses cold and hot fluids to alternately flow through the surface of the heat storage body (filler) in the heat storage chamber for heat exchange. The cold and hot fluids in the partition volume heat exchanger are separated by the solid partition and heat exchange is conducted through the partition, so it is also called the surface heat exchanger. The utility model relates to a corrugated tube positive displacement heat exchanger, which is mainly composed of an apparatus body, a steam coil assembly, a steam inlet and outlet, a cold and hot water inlet and outlet, etc. In order to prevent corrosion of the inner surface of the apparatus body, a layer of anti-corrosion alloy layer is sprayed on the surface, and a paint layer is brushed on the alloy layer. In addition, the original tube box is canceled, and the steam coil is directly externally connected through a flange, so that the utility model has simple and reasonable structure, long service life, and good heat exchange effect, Energy saving and other characteristics.
