How to deal with the flue gas problem of medium frequency electric furnace

Intermediate frequency melting furnace is mainly used for metal smelting. The temperature in smelting will be very high. A lot of flue gas will be produced in the melting process of metal, which will pollute the environment. So how to deal with the flue gas problem produced by intermediate frequency furnace? The following is mainly to introduce the specific methods

1. Flue gas purification. The purification of flue gas only depends on the precipitator. The selection of dust collector directly affects the collection effect, power consumption and long-term stable and reliable operation of the whole system.

2.Flue gas collecting device of medium frequency electric furnace. It includes dust collecting cover, off-line gas pipe pulse dust collector, boiler induced draft fan, etc.

Dust collecting cover is commonly used.There are two main types.
1.Furnace body whirlwind dust hood

The whirlwind dust hood has excellent vacuuming effect, takes up less space, can be tilted back and forth, and can be stopped at any position. The whirlwind dust hood can avoid Front turn furnace lid baking operator. The dust hood can effectively vacuum during the spheroidizing process before the furnace, which can’t be done with a traditional vacuum.

2. Front and rear tilting type insulation dust hood

The front and rear tilting type dust hoods through the hydrocylinder to make the whole dust hood can be opened in front or behind. It is necessary to change the opening mode of the dust hood by operating and changing the position of the positioning pin. The dust hood absorbs dust and exhaust gas through a certain amount of suction air to achieve and improve the exhaust emission effect.
Welded steel dust hood, which can be opened by hydraulic front and behind, connected to the exhaust emission and suction piping system through a flange on the rotating shaft of the furnace body.
When the entire dust hood is opened in the forward direction, the feeding operation is performed.
The entire dust hood can be opened in the reverse direction. This design facilitates the operation of the furnace lining without disassembling the dust hood, and facilitates the maintenance of the pouring port of the induction furnace.
