How to choose the right filter washing and drying equipment

- Jan 02, 2020-

The filtration, washing and drying equipment can finish the three processes of filtration, washing and monotony in a closed container equipment, and improve the utilization rate of the equipment. It can avoid the environmental pollution and the environmental pollution of materials, reduce the loss of material transportation, save the use of solvents, and is suitable for batch production. Let's talk about how to choose filtration, washing and drying equipment.

1. Material corrosion resistance. Generally, the materials with chloride ion content, from normal to high-temperature drying, have excellent corrosion resistance, and can still be stable and applicable to hydrochloric acid with concentration less than 1%. For high concentration hydrochloric acid and other strong corrosion solutions, Hastelloy alloy is a mature material in the market; The non-metallic materials such as polytetrafluoroethylene are also relatively stable in corrosion resistance, but the problems such as coating peeling are easy to occur in the application process of filter washing and drying equipment, which will be described in detail in the third point;

2. Material manufacturing process. As well known as the excellent corrosion resistance and stability of titanium material is the difficulty of its processing technology. Titanium material is special, and the typical problem is that it cannot be directly welded with other materials; However, considering the application cost, the pure titanium material is not very acceptable. Dingchang conducts process research and development for this kind of application to form a set of "composite titanium processing" process plan. Based on the alloy, composite titanium materials are processed as a whole. It has accumulated 16 years of process experience from the successful application of titanium materials.

3. Service life, performance and stability. Under the premise of maintaining the material quality, the manufacturing process of the filter washing and drying equipment is the key factor to determine the service life and stability of the equipment in the later period. The heat transfer effect of metal materials is almost the same, which is the material in the process of heat exchange; and in the case of alternate use of different temperatures, even different alloy materials have close shrinkage ratio, generally relatively stable.
