电炉的烟气粉尘的治理已经达到了一个新的水平， 电炉除尘设备目前运行情况如下： With the progress of industry, the efficiency of dust removal of electric furnaces is getting higher and higher. According to market analysis, the dust removal efficiency of some electric furnaces is as high as 97%. According to the emission requirements of the Ministry of Environmental Protection of China, Governance has reached a new level, and the current operation of electric furnace dust removal equipment is as follows:
1 ）各电 炉生产产地已广泛使用除尘设备布袋除尘器和电除尘器，除尘设备运行基本良好，效果显著，满足了环保要求 ( 1 ) Bag-type dust collectors and electric dust collectors for dust removal equipment have been widely used in the production areas of various electric furnaces . The dust removal equipment operates basically well, with significant results and meeting environmental protection requirements.
2 ）除尘 设备的主风机装机功率容量大，液力耦合器、变频器等调速装置已普遍应用于风机的启动、调速运行； ( 2 ) The installed power capacity of the main fan of the dust removal equipment is large, and speed control devices such as hydraulic couplers and inverters have been widely used in fan startup and speed operation;
3 ）一些断续生产工段，根据生产工艺特点，自动控制除尘 设备主风机高速、低速运行，具有良好的节电效果，如焦化除尘、高炉除尘、转炉一次除尘等 ( 3 ) In some intermittent production sections, according to the characteristics of the production process, the main fan of the dust removal equipment is automatically controlled to run at high and low speeds, which has good power saving effects, such as coking dust removal, blast furnace dust removal, and converter primary dust removal
4 ）另一些断续生产工段，由于自动控制较复杂，运行方式以最大烟尘量设定风机参数长期运行，耗电量大、调速装置未达到最佳应用状态，如电炉除尘、转炉二次除尘等。 ( 4 ) In other intermittent production sections, due to the more complicated automatic control, the operation mode sets the fan parameters with the maximum amount of smoke and dust for long-term operation, large power consumption, and the speed control device has not reached the optimal application state, such as electric furnace dust removal, converter two Secondary dust removal, etc.
5 ）一些连续生产工段，烟尘排放点比较多，但每个排放点烟尘量较小，除尘系统烟尘捕集罩较分散，采用一套除尘系统收尘，除尘系统主风机以最大风量长期运行，采用调解风管阀门控制风量来满足烟尘排放点的收尘，此运行方式耗电量也比较大。 ( 5 ) In some continuous production sections, there are many smoke and dust emission points, but the amount of smoke and dust at each emission point is small, the dust collection system dust collection hood is scattered, a set of dust collection system is used to collect dust, and the main fan of the dust collection system runs for a long time with the maximum air volume. The mediation duct valve is used to control the air volume to meet the dust collection at the smoke discharge point. This operation mode also consumes relatively large power.
(6) Based on the above situation, in-depth analysis of the actual production process, the use of existing equipment, and effective automatic control methods can further reduce the power consumption of the fan of the dust removal system and achieve the best power saving effect.
