Sodium Acetate Vibrating Fluidized Bed Dryer With Electrical Heating

Sodium acetate introduction:

Sodium acetate, also known as sodium acetate, is an organic substance that is easily soluble in water. It can be used as a buffer, mordant, for the determination of lead, copper, nickel, iron, culture medium preparation, organic synthesis, and film printing.

Fluidized bed technology:

Solid particles are evenly piled in a container with an open bottom to form a bed. If the fluid passes through from top to bottom, the particles do not move, and this bed becomes a solid bed. If the fluid passes through the bed from top to bottom, at a low flow rate, the situation is no different from a solid bed. When the flow rate increases, the particles move and expand the bed. When the flow rate increases further, the particles will move away from each other and move in the fluid. The greater the flow rate, the more intense the activity, and the particles move in all directions in the bed. The last situation is called the solid fluidized state, and the particle bed after the fluidized state is called a fluidized bed. The technology that applies it to actual production and life is the fluidized bed technology.

Characteristics of fluidized bed dryer:
If the gas-solid fluidized bed is compared to a boiling liquid layer, the particle group in the fluidized state is equivalent to the boiling liquid itself, and the bubbles rising through the bed are equivalent to the steam bubbles in the boiling liquid. Therefore, this fluidized bed has a special two-phase system. The particle group in the fluidized state is continuous, which is the continuous phase, also known as the dense phase. The bubbles are dispersed, which is called the dispersed phase, also known as the dilute phase. As long as the bed has a clear upper interface, there will be coexistence of dilute and dense phases, but the fluidized bed in this state is generally called a dense phase fluidized bed. If the gas velocity increases, the upper interface of the bed does not exist, and the fluidized bed in this state is called a dilute phase fluidized bed. In the dense phase of a normal gas-solid fluidized bed, the gas flow is very slow, almost laminar. At the interface where the bubbles contact the dense phase, the particles impact violently, causing great turbulence in the gas inside and outside the bubble, thereby strengthening the contact between the gas and the solid, which is conducive to heat and mass transfer. This is the benefit brought by bubbles, but bubbles can also cause two unfavorable situations, namely channeling and surging.

Operation parameters:
The fluidization velocity of the fluidized bed can be divided into the critical fluidization velocity and the carry-out velocity according to the different states of the bed. In fact, the diameter of the particles in the bed cannot be exactly the same. Each particle has a different value. When selecting the fluidization velocity, these different values ​​should be considered. Even if the particle distribution is narrow and the speed range is relatively wide, it should be considered that when the speed is too small or too large, there will be abnormal phenomena such as channeling or surging.
In order to improve the production intensity of the equipment, it is generally hoped to use the largest possible air flow velocity. If a high-efficiency cyclone separator is installed behind the fluidized bed, it is also possible for the air flow velocity to be greater than the carry-out velocity of some particles. This has been applied in actual production. Increasing the air flow velocity cannot only consider the operational flexibility of the fluidized bed itself, but is also subject to the following conditions: the contact time between the gas and the solid must be guaranteed, and the capacity of the gas conveying machinery must adapt to the increase in fluid resistance.
