Why need to clean the heat exchanger?

- Jul 31, 2018-

The reasons that need cleaning the heat exchanger are as following

First: improve heat transfer efficiency, save energy; second: extend equipment life Third: improve production efficiency and product quality Fourth: reduce economic losses.

Heat exchanger cleaning reasons

Cleaning In the chemical industry's production process, due to many reasons, many heat exchangers and pipelines, such as coking, oil, scale, deposits, corrosion products, polymers, fungi, algae, Mud and other dirt.

The dirt generated will invalidate the equipment and pipelines, and the equipment system will have production degradation, energy consumption, material consumption and other adverse conditions. When the dirt corrosion is particularly serious, the process will be interrupted, and the equipment system will be forced to stop production, directly causing various causes. Economic losses, and even malignant production accidents may occur.

In the scientific development today, it is almost impossible to completely avoid the generation of dirt. Therefore, the cleaning of equipment such as heat exchangers has become an indispensable part of industrial production, especially in the production of petrochemical and thermoelectric plants.

Heat exchanger cleaning Million industry cleaning is generally used; chemical cleaning and high pressure water jet cleaning two methods.

Heat exchanger cleaning purpose

There are two main functions and purposes of equipment cleaning.

First, resume production

In the process of industrial production, sometimes the equipment or local pipeline lines are fouled and blocked due to unexpected situations caused by improper operation, which affects the normal operation of production. For this situation, it is mainly to quickly remove dirt, to ensure that the production equipment can operate normally and return to normal production.

Second, restore the production efficiency of the device.

For example, the scaling of chemical equipment causes the heat transfer coefficient of heat exchangers and other equipment to decrease, the flow area of ??the pipeline is reduced or the flow resistance is increased, the consumption of energy and materials is increased, and the production efficiency is significantly reduced. At this time, the production efficiency of the production equipment is restored by cleaning and descaling.
