Gas cleaning of blast furnaces from the resulting slag, pollutants, and vaporous inclusions is carried out in order to maintain a high level of performance of the equipment itself and compliance with established sanitary standards. The procedure is performed using special cleaning units. In this case, gas purification waste additionally:
- Subjects to the procedure of separating sludge from dust.
- Used to produce agglomerate used for smelting cast iron.
A more innovative and efficient way to use waste is to briquet it. Finished briquettes are used in the foundry production of blanks or finished products.
Main types of gas cleaning
Gas cleaning systemsfor blast furnaces are designed and developed taking into account the specifics of production. The volumes of smelted metal, production capacities and types of auxiliary equipment are taken into account. Industrial blast furnace gas cleaning can be carried out using the following technologies:
- Installation of special scrubbers or “wet” method - small particles released during the production process are absorbed by an absorbent (ordinary industrial water is used) and glued together. Types of scrubbers - centrifugal, plate, packed or hollow.
- "Dry" cleaning using textile bags (sleeves), particles settle on their inner surface. The cartridges consist of a protective mesh and corrugated material that traps harmful emissions, and are cleaned using compressed air. Cyclones, under the influence of centrifugal forces, contaminants settle on the walls of the installation’s working chamber.
To install certain types of systems, the gas cleaning room is first inspected and checked for the level of contaminants. The availability of conditions for the selected methods to fulfill the parameters established by sanitary standards is determined.
Free consultation and assistance in selection
A wide selection of options for blast furnace gas cleaning systems is presented on the Fakel company website. The company’s specialists provide services on an official commercial basis:
- Design and approval of the project in permitting structures.
- Selection of the required design and dimensions of the treatment plant.
- Delivery equipment.
- Installation work and commissioning.
The estimated cost of the selected project is discussed with clients individually. Services are provided after concluding a contract with a guarantee of quality and compliance with established deadlines.
