In industrial production, heat ex changers, as key heat – exchange equipment, are widely used in numerous fields such as petroleum, chemical engineering, power, and metallurgy. However, during long – term operation, dirt easily accumulates inside heat ex changers. For example, in the petrochemical industry, impurities, salts, and various chemical substances in crude oil will form stubborn scale layers on the pipes and heat – exchange surfaces of heat ex changers. These dirt not only reduce the heat – transfer efficiency of heat ex changers, resulting in energy waste and increased production costs, but in severe cases, they may also trigger equipment failures, affecting the continuity and safety of production. Therefore, efficient cleaning and maintenance are crucial for the stable operation of heat ex changers and the improvement of production efficiency. Thus, the high – pressure water heat ex changer automatic cleaning device has emerged.

Working principle and core structure

The automatic cleaning device for high – pressure water heat ex changers mainly utilizes the powerful kinetic energy of high – pressure water jets to achieve the cleaning purpose. Tap water is pressurized by a high – pressure pump, and the pressure can reach several hundred or even thousands of MPa. Subsequently, it is ejected through a specially designed nozzle at an extremely high speed of 200 – 500 meters per second. This high – speed water flow is like a dense stream of bullets, possessing huge impact energy, and can easily peel off the dirt on the surface and inside the pipes of the heat ex changer.

The core structure of this device is exquisitely complex. As the key to automated operation, the hole – alignment system, under the command of the control program, can automatically, one – by – one and orderly send the spray heads into the holes of the heat ex changer without manual operation, greatly improving the accuracy and efficiency of cleaning. The high – pressure cleaning head is the component that directly executes the cleaning task. It can accurately spray high – pressure water onto the parts of the heat ex changer that need to be cleaned, ensuring that the dirt is thoroughly removed. The control system is the “brain” of the entire device. Through programming, it realizes the automatic control of the entire cleaning process, including the precise adjustment of key parameters such as the concentration of the cleaning agent (if used), cleaning speed, and cleaning time, to meet the cleaning requirements of different types and degrees of dirt. The conveying system is responsible for the transportation of the cleaning agent and cleaning waste liquid, ensuring the smooth progress of the cleaning process. The waste liquid treatment system purifies the waste liquid after cleaning, making it meet national emission standards and effectively avoiding environmental pollution.

Outstanding advantages

1.Significantly improved cleaning efficiency: Traditional manual cleaning of heat ex changers is not only slow, but also difficult to guarantee the cleaning quality. Especially for the complex internal structure of heat ex changers, there are often many blind spots in manual cleaning. The high – pressure water heat ex changer automatic cleaning device realizes automated cleaning, which can complete a comprehensive cleaning of the entire heat ex changer in a short time. This greatly improves the cleaning efficiency, reduces the equipment downtime, and provides a strong guarantee for the continuous production of enterprises.

2.Reduced equipment maintenance costs: Regularly using this device to clean the heat ex changer can effectively prevent equipment corrosion and damage caused by long – term dirt accumulation, thus extending the service life of the heat ex changer. At the same time, automated cleaning reduces manual input and labor costs. Overall, it significantly reduces the equipment maintenance costs.

3.Stable and reliable cleaning effect: The automatic hole – targeting system ensures that each channel of the heat ex changer can be accurately cleaned through high – precision positioning, avoiding missed or repeated cleaning. Moreover, it can ensure that each channel receives the same water jet pressure and flow rate, resulting in a uniform and stable cleaning effect, and ensuring that the heat transfer efficiency of the heat ex changer is restored to the maximum extent.

4.Obvious environmental protection and energy – saving advantages: High – pressure water cleaning is a physical cleaning method. It does not require the use of a large amount of chemical cleaning agents, thus avoiding environmental pollution problems caused by chemical cleaning. In addition, during the cleaning process, the control system can accurately adjust the water flow and pressure according to the actual situation, effectively saving water resources and energy.

Application

1.Petrochemical industry: In processes such as petroleum refining and chemical product production, heat ex changers are indispensable equipment. The automatic high – pressure water heat ex changer cleaning device can be used to remove various types of dirt formed in the heat ex changer during crude oil processing, such as asphalts and coke, ensuring the efficient operation of the equipment and the stable progress of production.

2.Power industry: Whether it is thermal power generation, hydro power generation or nuclear power generation, heat ex changers are widely used in cooling systems, steam generation systems, etc. The automatic cleaning device can effectively clean dirt such as scale and rust in the heat ex changer, improve energy conversion efficiency, and ensure the safe and stable operation of power generation equipment.

3.Metallurgical industry: During the smelting of steel and non – ferrous metals, heat ex changers are used to cool high – temperature molten metal and recover waste heat. This device can help remove dirt formed due to high – temperature oxidation and metal impurities, maintain the performance of the heat ex changer, and contribute to the efficient progress of metallurgical production.
