1. Formation of fluidized bed
In a vertical fluidized bed tube furnace, gas passes through the tube bundle from bottom to top. By controlling the flow rate and pressure of the gas, solid materials or sample particles can form a fluidized bed within the tube bundle. In this state, the frictional force and eddy current between gas and solid particles keep the solid particles suspended, thereby increasing the contact area between gas and solid, improving the efficiency of heat treatment or the uniformity of sample processing.
2. Heat treatment process
Sample placement: During heat treatment, introduce materials and gases into the tube bundle. The sample particles are placed in a fluidized bed.
Gas flow: When gas passes through a fluidized bed, it drives the flow of sample particles, achieving uniform heating or processing. By controlling parameters such as gas flow rate, temperature, and pressure, the process can be accurately controlled and processed.
Heat transfer: Adequate contact between gas and solid particles promotes heat transfer and improves heat treatment efficiency.
3. Application areas and advantages
The vertical fluidized bed tube furnace has multiple advantages, such as uniform heating, high heat transfer efficiency, and fast reaction speed. These advantages make it widely used in multiple fields:
In the field of chemical engineering, it can be used for processes such as catalyst regeneration, drying, and calcination.
In the field of metallurgy, it can be used for processes such as preheating and reduction of ores.
In the field of materials science, it can be used for sintering and heat treatment processes of materials such as ceramics and glass.
4. Operation precautions
When using a vertical fluidized bed tube furnace, the following points should be noted:
Ensure effective grounding of the furnace to ensure safe use.
There should be no flammable or explosive materials around, and good ventilation should be maintained.
Be careful not to exceed the rated temperature of the furnace.
Regularly check whether the wiring of the electric furnace, controller, etc. is in good condition, and whether the indicator is stuck or stuck.
Keep the furnace clean during use and promptly remove oxides and debris from the furnace.
In general, vertical fluidized bed tube furnaces achieve the flow and uniform heating or treatment of solid powder or sample particles through the fluidization characteristics of gas. This working principle makes it have broad application prospects and research value in multiple fields.Click to learn more vertical tube furnaces!
