What a way to cleaning heat exchangers

When using heat exchangers need to be protected from scale, however, this protection is not always efficient. Also often turns out to be much cheaper to periodically perform cleaning of heat exchangers, than to install additional hardware and buy chemicals, and special filters . Such works as flushing, intended for descaling and other contaminants from the walls of those parts that are constantly in contact with water.

Cleaning and washing of the heat exchangers can be implemented in different ways, each of which has its advantages and disadvantages. Let’s look at the basic types of cleaning:

• chemical flushing heat exchangers consisting of three stages: water and alkaline treatment. Using various acid scale and other deposits or soluble or come into reaction and turn into sludge. This sludge is removed by using the flow of water, and then to protect metal surfaces of the heat exchanger it is treated with alkaline solutions;
• mechanical cleaning of heat exchangers based on removal of scale and other contaminants using the special tool for cleaning nozzles, roller type centrifugal and other things from the zmivom was mudslinging by jets of water;
• hydraulic flushing heat exchangers based on breaking down the deposition by high pressure water jet and simultaneously remove them using the flow of water. To use this method must use the hydrodynamic pressure increased installation, which can create a gun with nozzle for the formation of the Jet pressure.

What a way to cleaning heat exchangers

In some cases, you can use e ultrasonic cleaning. To perform a flushing heat exchangers with the lowest cost and the best effect you should consider a lot of different options, in particular, the design features of the exchangers, the condition of the heating surfaces, the thickness and the chemical composition of deposits. Depending on the data factors determined the best way to clean heat exchangers.
