烟气净化除尘系统

保护生产环境和生态环境,是我国一项基本国策。所以国家逐渐提高矿热炉生产中烟气的排放浓度标准。也意味着对烟气净化设备的要求越来越高。
矿热炉在冶炼过程中,将产生大量的烟尘。2台25500kVA硅铁电炉每年约排放烟气量198000万标立米,烟气含硅尘7920吨。产生的大量二氧化硅粉尘如直接向大气排放,将严重污染环境,同时也将恶化工人的劳动条件。

烟气净化除尘系统

Flue gas purification and dust removal system

保护生产环境和生态环境,是我国一项基本国策。所以国家逐渐提高矿热炉生产中烟气的排放浓度标准。也意味着对烟气净化设备的要求越来越高。

矿热炉在冶炼过程中,将产生大量的烟尘。2台25500kVA硅铁电炉每年约排放烟气量198000万标立米,烟气含硅尘7920吨。产生的大量二氧化硅粉尘如直接向大气排放,将严重污染环境,同时也将恶化工人的劳动条件。

To protect the production environment and ecological environment is a basic state policy of our country, so the country gradually improve the standard of the discharge of flue gas in the production of ore furnac.It means that the requirement of the equipment for flue gas purification is getting higher and higher.|

The ore furnace will produce a large amount of flue gas in the smelting process. Two 25500kVA ferrosilicon furnace will produce about 198000 million standard cubic meters amount every year and flue gas containing silica dust 7920 tons. If the oxidation silicon dust greatly produced is directly emission to atmosphere, it will seriously pollute the environment. At the same time, it will evilthe  chemical working conditions.

密闭电炉负压净化系统

煤气净化系统能适应电炉在不同的炉况下运行,能够严格将系统压力、温度等参数控制在规定的范围内,并具有可操作性,从而保持系统稳定,避免焦油析出与粉尘堵塞管道,电炉炉面压力也能维持在微正压状态。

系具有较高的安全性能,系统保证在安全压力下输送,现场电气设备采取隔爆设计、机械设备、管道等均采用防爆设计,系统内所有烟气流经设备及管道安装氮气保护装置,并在关键部位安装“O2”、“ H2”含量监测仪表并设自动报警装置,全系统采用DCS监控,如有异常能自动报警或紧急切断气路停止运行,防止起火爆炸。

净化系统过滤的粉尘进行全密闭输送,并集中处理,避免二次扬尘和污染

Gas purification system can adapt to the furnace in different furnace operation and strictly control the system pressure, temperature and other parameters within the scope of the provisions and has maneuverability, so as to maintain the stability of the system and avoid tar precipitation and dust blocking the pipeline. The furnace surface pressure also can be maintained the micro positive pressure.

The system has a higher safety performance and ensures to delivere at safety pressure. The on-site electrical equipment all adopts flameproof design, machinery and equipment, pipelines etc. are used anti simmer design. The nitrogen protection device is installed in all the equipment and piping that flue gas flows through. The ”O2”, ”H2” content monitoring instrument and the automatic alarm  are  installed in the key parts. The whole system uses DCS monitoring. If there is something abnormal, it can automatically alarm or cut off the gas road to stop running in emergency to prevent fire explosion.

The dust filtered by the purification system will be fully enclosed transported and centralized processing to avoid the secondary dust emission and pollution.

正压袋式除尘器系统

电炉烟气净化系统运行时,含尘烟气由烟罩通过风管引至自然空冷器,将烟温从450℃冷却至220℃,然后进入预处理器,将烟气中的大颗粒粉尘和带有火星碳粒除掉,以防烧坏布袋和提高硅粉的品位。再由引风机压入正压布袋除尘器过滤,含尘烟气经玻纤覆膜滤料过滤后排放的烟气含尘浓度低于国家排放标准(50mg/Nm3)。净化后的烟气由位于除尘器顶部的排气室排放。
