Description

Smoking device for dust removal equipment

Technical Field

The utility model belongs to the technical field of intermediate frequency furnace equipment, and particularly relates to a smoking device for dust removal equipment.

Background

The intermediate frequency furnace is a power supply device which converts the power frequency 50HZ alternating current into intermediate frequency (more than 300HZ to 1000 HZ), converts the three-phase power frequency alternating current into direct current after rectification, then converts the direct current into adjustable intermediate frequency current, supplies the intermediate frequency alternating current flowing through a capacitor and an induction coil, generates high-density magnetic force lines in the induction coil, cuts metal materials contained in the induction coil, and generates great eddy current in the metal materials.

In the process of smelting metal at high temperature by using an intermediate frequency furnace, a large amount of flue gas is generated, and the flue gas contains a large amount of high-harm and high-toxic gas. If released into the air, the air can not only influence the physical health of workers in factories, but also cause serious air pollution, thereby bringing harm to the physical health of people around the world.

From the design point of the intermediate frequency furnace smelting process flow, the low-level dust hood and dust removal equipment are adopted, so that the flue gas in the whole intermediate frequency furnace smelting process can be treated. However, there are still many disadvantages to such dust removal apparatus in use: the fume suction hood is arranged above the furnace mouth of the intermediate frequency furnace, so that the feeding and discharging operation of the furnace mouth of the intermediate frequency furnace is inconvenient, and the fume suction hood is arranged next to the furnace mouth, so that welding steel bars of the fume suction hood are easy to fall off, and the risk of thermal deformation is increased;

therefore, some enterprises adopt high-level dust hoods and dust removing equipment, but the distance between a smoke suction opening of the smoke suction hood and an intermediate frequency furnace opening is more than 800mm, and smoke dust generated by smelting does not rise linearly but flies along with wind direction, so that the smoke hood cannot be fully absorbed, and pollution is caused to workshops.
