How should the air cooler carry out daily maintenance work?
An air cooler is a heat exchanger that uses air to cool a hot fluid. The hot fluid in the tube exchanges heat with the air outside the tube through the tube wall and fins, and the air used is usually supplied by a ventilator. Air coolers can be used for cooling or condensing. They are widely used in: condensing oil refining and petrochemical tower top steam; reflux oil and tower bottom oil cooling; various reaction products cooling; circulating gas cooling and power station steam turbine exhaust Condensation.
Air coolers mostly contain calcium, magnesium ions and acid carbonates because of the cooling water. When cooling water flows over the metal surface, carbonates are formed. In addition, the oxygen dissolved in the cooling water can cause metal corrosion and form rust. Due to the generation of rust, the heat exchange effect is reduced. In severe cases, cooling water has to be sprayed outside the shell. In severe cases, the tube will be blocked and the heat exchange effect will be lost. Research data shows that scale deposits have a huge impact on the loss of heat transfer. As the deposits increase, energy costs will increase, saving energy, extending the service life of equipment, and saving production time and costs.
For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (pickling), etc. have encountered many problems when cleaning the equipment: they cannot completely remove deposits such as scale, and the acid causes corrosion to the equipment and forms loopholes. , The residual acid will cause secondary corrosion or under-scaling corrosion to the material, which will eventually lead to the replacement of equipment. In addition, the cleaning waste liquid is toxic and requires a lot of money for wastewater treatment.
The air cooler manufacturer tells everyone to use the air cooler to pay attention to routine maintenance, which can extend its service life.
