Dedusting System of Ladle Furnace

Description

Dedusting System of Ladle Furnace

Fume from electric steelmaking furnaces is one of the main sources of pollution in iron and steel enterprises. It has the characteristics of large emissions, high flue gas temperature, fine dust and hydrophilicity, making it difficult to capture and purify. With the structural adjustment of iron and steel industry, the continuous development of electric furnace steelmaking technology such as ultra-high power, enhanced smelting and hot metal charging, and the continuous improvement of environmental protection requirements, the control of electric furnace smoke and dust has become a key link in the steelmaking workshop. The dedusting system of the ladle refining furnace usually adopts the method of “airtight cover/roof cover” + fourth hole exhaust smoke + mechanical cooler + sub-chamber back-blowing large bag filter or pulse cleaning bag filter”, which can be arranged according to the working conditions of the plant and the workshop layout. and the expected flue gas emission standards, and appropriately adjust the flue gas collection and treatment methods.

Equipment Composition and Processes

The ladle furnace dedusting system in the workshop mainly includes dust hood, pipeline, dust removal equipment, fan, dust transmission device, etc. the main processes are as follows:

► use the dust hood and flue gas collection port to capture the dusty gas generated in the process.

► the trapped dusty gas is transported to the dust removal equipment along the air duct under the action of the fan.

► separate the dust in the dust removal equipment.

► the purified gas is discharged to the atmosphere.

► collect and deal with the separated dust.

Parameters

Design performance index

1. Capture rate > 95%

2. Smoke emission concentration < 30mg / Nm3

3. Post dust < 10mg / Nm3 (deducting background value)

4. Other relevant specifications and requirements formulated by the environmental protection department

Features

Flue gas capture mode

The flue gas produced by LF ladle refining furnace is usually captured by furnace cover roof or mobile semi closed cover; When the furnace roof is used to capture the flue gas of the refining furnace, part of the flue gas escapes from around the electrode hole. Therefore, the mobile semi-closed cover is more conducive to capturing the flue gas during smelting.

The mobile semi-closed cover is composed of a mobile cover and a fixed cover. A thermal insulation layer is arranged in the cover to prevent thermal deformation of the cover body. Remove the moving cover during LF furnace maintenance or electrode change.
