Ventilation shaft patented technology

  Technology Introduction: Due to large investment and high technical difficulty, system conditions such as fluctuations more complex factors, the current domestic flue gas treatment within the ventilation shaft or a blank. And I capture that part of the original title, made ​​the first project examples in Wuhan, and patented technology.

  BOF steelmaking dust ventilation shaft in BOF process, when the Front cover opens to the converter and against adding scrap iron, and after the converter hoods open when the molten steel, will produce a large dust fumes. Although the molten steel for only 3min about, and in the case of secondary dust seal cover opened against the iron and steel flue gas produced when the plant directly jumped to the roof. Against the hot metal and the A small portion of the flue gas carrying dust settling onto the furnace platform, driving and other equipment, causing safety hazards and environmental pollution workshop equipment operation, and greater impact on the health of workers. Another most smoke directly into the atmosphere through the ventilation shaft roof, the roof and the surrounding environment pollution.

  The clever use of the existing converter technology secondary flue gas dust removal system for the converter in the molten iron and a smoke against the intermittent ventilation shaft generated when the molten steel within the characteristics of sudden, secondary flue gas dust removal system in the original converter Based on the plans to increase the dust removal facilities for ventilation shafts, ventilation shafts will be incorporated into the existing secondary flue dust flue gas dust removal system, the formation of a new dust removal system. Flue gas so that we can control ventilation shaft straight row, without affecting the original secondary flue gas dust removal effect. And less investment, high collection efficiency, the system is stable, less maintenance, low operating costs, spend very little cost to solve a big problem.

  Steelmaking converter smoke ventilation shaft straight row, resulting in waste of resources, environmental pollution, damage to the equipment, the enterprise will bring huge losses. Therefore, successfully developed a converter steel dust ventilation shaft project, has a very good social and economic benefits to meet the spirit of the national energy saving.
