Solutions to scarring at the bottom of the tower in the high-tower granulation production process
Thread Content
In the high tower production process, particles fall from the top of the tower and are cooled by cold air; they then settle on the three-level funnels at the bottom of the tower, where more particles accumulate there. Over time, a large amount of uncooled particles adhere to the walls of these funnels, forming thick layers of scale. Usually, manual cleaning is carried out at regular intervals, but this is time-consuming and labor-intensive. Do any of the experienced colleagues have any other good methods to deal with this problem of scale formation?
Supplying cold air (dehumidified and cooled air) into the tower is one of the most effective methods. However, when air is supplied into the tower, the volume of air required is very large, which results in high equipment costs and operating expenses. For a high tower with a capacity of 200,000 tons per year, approximately 250,000 m3/h of dehumidified and cooled air is needed to be supplied into the tower. Most manufacturers prefer to use air-cooled dehumidifiers at the cooling rollers at the end of the process in order to reduce the temperature of the packaging
