Four common methods for roses microwave equipment

What are the common methods for the common materials used in the microwave microwave cleaning equipment? Let's look at it:

1. Meeting the needs of the materials to be processed The main task of the rosette microwave cleaning equipment is to kill the given materials. Due to the wide variety of materials handled by the killer, it covers many fields such as grain, food, pharmaceutical, chemical, forest products, paper, metallurgy, etc., and the products are hard to count. The requirements for materials to be smashed vary widely. For example, chemical reagents, pharmaceuticals, electronic materials, electrical ceramic materials, etc. must not be mixed with iron ions. Therefore, carbon steel materials should be avoided in equipment selection. In addition, if the moisture content in the material contains acid, alkali, salt, organic solvent, etc., it will be corrosive to different metal materials. Especially in the heating process, the corrosion of the material will be intensified, so the appropriate material should be selected according to the characteristics of the moisture contained in the material.

2. Select materials for the equipment installation environment In many cases, although the above conditions can meet the requirements, we must also pay attention to the material requirements of the equipment installation environment. If the equipment is installed in a chemical plant, the environment must be carefully considered for the corrosion of the equipment, control system, and electrical system.

3, for the process of selecting green materials, different materials are different. I have designed a high-temperature type of greening device to polymerize the inorganic salt while killing it. It is required to kill the hot air temperature above 800 °C, and the green material has to choose high-temperature resistant stainless steel, but considering that the greening room is not in the high temperature zone, according to the calculation, only the high temperature resistant material is selected in the high temperature zone. It has been running for more than a year and everything is fine.

4, for the rose microwave cleaning equipment selection materials mentioned earlier, there are many types of green machine, each type of machine works differently, so should also be fully considered when selecting materials. For example, when the gas streamer is used to kill magnesium oxide, the material is high in the gas flow tube, the magnesium oxide material is hard, and the wear on the turning wall of the green tube is severe. Therefore, it is necessary to design an anti-wear structure or select a wear-resistant material in this area. . For another example, compared with carbon steel, the thermal conductivity of stainless steel materials is significantly lower than the former. Therefore, in the microwave curing equipment based on conduction heat transfer, if stainless steel is selected as the main material, the heat exchange area of ​​the equipment should be calculated by the thermal conductivity of stainless steel. The engineering example proves that when selecting a steam heat exchanger, the stainless steel material is 30% larger than the carbon steel material.

The above four are common methods for the material of the rose microwave device.
