How to clean heat exchanger equipment?

On-line cleaning can be understood as in-situ cleaning or in-situ cleaning, which is defined as: no disassembly of equipment or components, under closed conditions, with a certain temperature and concentration of cleaning fluid on the cleaning device to a strong role, so that the surface of the instrument and equipment cleaning and sterilization methods. The advantage is that the equipment does not need to be shut down and does not affect the normal production and use. The disadvantage is that the cleaning effect is not very good compared to offline cleaning. If the cleaning time is longer, it will affect the stability of the equipment operation.

Causes of Expansion of Spiral Plate Heat Exchanger

After the heater is in place, a level gauge is used to level the heat exchanger, so that each pipe can be connected to the pipeline without any force. After leveling, the inclined shim can be welded firmly with the cheese seat, but not with the flat shim or slide plate below. When more than two overlapping heat exchangers are installed, the upper heat exchanger shall be installed after the lower heat exchanger is located and the anchor bolts are fully fixed.

The operation method of the reaction kettle?

Before operation, carefully check whether there is any abnormality. During normal operation, do not open the upper cover and touch the connection terminals on the board to avoid electric shock. It is strictly forbidden to operate under pressure. During the pressure test with nitrogen, carefully observe the change of pressure gauge, reach the pressure test pressure, and immediately close the nitrogen valve switch; The temperature rise speed should not be too fast, and the pressure should also be carried out slowly, especially the stirring speed is allowed to increase slowly.
