Mechanical turbulence springs built into the tube bundle of petrochemical water coolers prevent scale formation inside the tubes
Thread Content
In petrochemical plants, circulating water generally flows inside the tubes of water coolers. A large portion of them tends to develop scale after operating for some time. The heat exchange efficiency declines, and in severe cases, heat exchange ceases to function. For certain applications where it is suitable to use mechanical springs installed inside pipes, as the circulating water flows under a certain pressure, the springs move radially and linearly within the pipe, rubbing against the inner wall of the pipe; this helps to prevent the formation of scale on the inner wall of the pipe, and this approach has proven very effective over many years of use. This is a method to prevent scale formation. However, using this method requires that the circulating water contain no solids such as stones, as these can interfere with the operation of the turbulence generator and reduce its effectiveness.
In petrochemical plants, water coolers typically use circulating water as the cooling medium. To avoid the problem of water scale forming inside the water cooler tubes after long-term operation, the method of installing mechanical springs can be employed. This type of spring can move radially and linearly within the pipe under the force of water flow, and it prevents scale formation by rubbing against the pipe walls, offering good performance over time. It should be noted that this method requires that the circulating water contain no solid impurities such as stones, as this could affect the proper operation and effectiveness of the turbulence generator. .
Is this kind of application widely used these days?
Which heat exchanger manufacturer will produce it? Could you tell me?
The disadvantages of this method affect the flow rate of the cooling water. The movement of the spring inside the tube causes mechanical wear on the heat exchange tubes; if the spring falls out and gets stuck in the valve opening, it can damage the valve equipment as well as the pump rotor. The proper approach should be to carry out water quality treatment, improving the water quality in order to reduce or eliminate such structural phenomena. For reference.
A relatively innovative approach that is worth considering
Using physical scale inhibition is also a good option. Our company’s microwave scale prevention and removal equipment is installed on the inlet pipe of the water cooler; by introducing microwave signals into the water cooler, scale formation can be prevented in real time. The product is available for trial use. WeChat: TigerPeng2014
