Problems solved by technology

The granular material on the fluidized bed will accumulate more and more electricity as it continues to move toward the outlet, so it is necessary to effectively eliminate the charged particles near the outlet, but because the bottom of the fluidized bed has a certain pressure Hot air, it is difficult to achieve the entry and uniform mixing of ion wind at this stage

Embodiment 2

[0032] In Example 2, static monitoring, discharge test and static elimination can be carried out on the water-containing material. After the wet material enters from the feed port (1), the potential becomes higher due to the action of the static electricity generating rod (4), and at the same time, it becomes a high-potential charged particle under its own vibration, collision and friction. The potential carried by the charged particles can be measured by an electrostatic potential sensor (5) fixed above the vibrating fluidized bed. By changing the position of the adjustable spherical electrostatic needle (38) to induce corona discharge, it can induce brush discharge when it moves to the static discharge plate (24), and the static discharge outlet (9) induces corona discharge and brush discharge. The discharge capacity of the three mechanisms can be measured by the connected electric meter.

Embodiment 3

[0033] In Example 3, the static electricity generated during the drying process of the water-containing material can be eliminated. After the wet material enters from the feed port (1), the potential becomes higher due to the static electricity generated rod (4), and at the same time, it becomes a high-potential charged particle due to its own vibration, collision and friction. The points carried by the charged particles can be measured by the electrostatic potential sensor (5) fixed above the vibrating fluidized bed. When the charged particles reach a dangerous electric potential, the two inlet branch pipes near the outlet end of the vibrating fluidized bed will inhale the ion wind generated by the ion gun (15) through the Venturi device (16) to neutralize the high-potential charge. particles.

Description

technical field [0001] The invention relates to the field of drying granular materials containing water, in particular to the intelligent adjustment and static elimination of particles that are prone to static electricity accumulation and explosion hazards in the airflow drying process. Background technique [0002] In recent years, with the progress and development of science and technology, vibrating fluidized bed drying technology has been widely used in industrial production and agricultural production. The vibrating fluidized bed is a fluidized bed supported on a set of springs, and the exciting force is provided by the exciting motor, so that the material is thrown on the perforated plate to the discharge end; the hot air is blown in from the bottom of the perforated plate, and the heat is transferred to the material , and carry the vaporized moisture in the material to be discharged from the exhaust port. For some special high-insulation combustible granular material...
