Description

Heat exchanger automatic cleaning system {HEAT EXCHANGER AUTOMATIC LANSING SYSTEM}

The present invention relates to an automatic cleaning system for a heat exchanger, and more particularly, is implemented to automatically inject a hose for high pressure cleaning into each tube of a heat exchanger while minimizing the shaded area requiring manual work by the operator. It relates to a heat exchanger automatic cleaning system.

The heat exchanger is a device that is installed in a mechanical device such as a hydraulic device such as a press or a power generating device such as an engine, and cools the heat of high-temperature working oil or coolant while the mechanical device is running.

The heat exchanger configured in such a mechanical device can be divided into a water cooling type and an air cooling type. Smaller mechanical devices use light air-cooled mechanical devices even if their cooling capacity is low, but a water-cooled heat exchanger with high cooling efficiency is used for medium and large mechanical devices.

The water-cooled heat exchanger is repeatedly used in a pressurized state in a hydraulic system, so that the heated working oil surrounds the tube of the heat exchanger, and the working oil is cooled while exchanging heat with the cooling water flowing inside the tube and returned to the hydraulic system.

Water-cooled heat exchangers are inexpensive and have high cooling efficiency, but if the tube through which the cooling water circulates is not cleaned, impurities in the cooling water are fixed in the tube.

If the tube is clogged by impurities, the performance of the heat exchanger is significantly degraded.

Since most of the tubes are small in diameter, it is difficult to clean them with a physical method using a cleaning brush, and most of them are chemically cleaned by injecting a cleaning solution. There is a high water jet cleaning method using a high pressure hose, and most of the methods (90%) that work during the large water purification period in most chemical industrial complexes use the high water jet cleaning method.

In addition, in the case of the existing heat exchanger cleaning device, serious accidents due to the work environment (closed space) and personnel accidents due to high pressure water in the process of washing by manually spraying high-pressure water using a high-pressure hose Had a problem that is frequently generated.

On the other hand, the above-described background technology is technical information that the inventor possessed for derivation of the present invention or acquired during the derivation process of the present invention, and is not necessarily known to be known to the general public prior to filing the present invention. .
