Purification treatment of oil fume in quenching production line

Purification treatment of oil fume in quenching production lineA metal hot working process in which metal materials are heated, insulated, and cooled in a certain medium, and their properties are controlled by changing the metallographic structure on the surface or inside of the material. However, during the heat treatment process, the high-temperature workpiece enters the medium cooling process and generates huge oil and smoke exhaust gas, causing the workshop to be filled with smoke, the floor to be greasy, and accompanied by a stimulating odor. nocompleteDuring combustion, black gas is produced, accompanied by a mixture of particles, commonly known as black smoke. How to remove these industrial waste gases requires component analysis and corresponding treatment plans.

When the high-voltage electric field formed between the cathode and grounded anode of a high-voltage DC power supply passes through particles with a diameter of less than 0.5um, negatively charged gas ions are generated due to corona discharge at the cathode and ionization of the gas. Under the action of electric field force, when moving towards the anode and colliding with smoke particles during the movement, the dust particles are negatively charged. After the charged dust particles reach the anode, they release the electrons they carry, and the dust particles deposit on the anode plate, thus purifying the gas.

Purification treatment of oil fume in quenching production lineWhen the dusty airflow passes through the flame arrester, it first hits the upper baffle, and then under the guidance of the upper baffle, it hits the lower baffle again, and then the airflow passes through the flame arrester.

During the two impacts, the large particles in the dusty airflow had reduced kinetic energy and were separated, resulting in the separation of sparks (high-temperature metal debris).

It is a device that uses a high-voltage electrostatic field to ionize and adsorb oil fumes flowing through it. It can effectively remove a large amount of oil fumes generated in industries, catering and other fields, not only protecting the environment and promoting health, but also saving energy and resources.

The device adopts the method of applying high voltage direct current between two plates, forming a strong electrostatic field in the air. When gases containing dust or other small substances (such as PM2.5) pass through this area with a static field, the following reactions occur:

Due to the difference in positive and negative loads, slight particles with less positive or negative energy are directed towards the cup collecting plate under sufficient strength capacity;

Due to the dominance of particles of the same size on different orders of magnitude, they can only be used when the wind speed is appropriate and the collection efficiency factor is taken into account;

For particles that are difficult to collect but can be washed offline and fall into the collection cup, they are electrostatically adsorbed to each other. During this process, tiny substances with loads will be attracted to the plates and deposited inside the cup.
