为了更有效地利用高炉炉顶煤气的能量和提高炉顶余压发电设备回收的电力,日本钢管公司福山厂与三菱重工共同开发了采用干式高压电除尘器的高炉煤气干式回收系统,并于1985年5月使世界上第一台实用装置在福山2号高炉上投入运行。本文介绍了试验经过和实用装置的运行情况。1.小规模半工业性试验(1) 试验目的。一是确认蓄热缓冲器的效果,设计时的计算公式及高炉炉尘对它的影响(堵塞、磨损等);二是验证干式电除尘的集尘性能和高温高压下设备的安全性以及排尘的方式。(2) 试验设备。主要由蓄热缓冲器和干式电除尘器组成。试验蓄热缓冲器直径1m,蓄热室用热风炉格子砖砌筑,高9m。
In order to make more efficient use of the energy of blast furnace top gas and increase the power recovered from the top pressure generating equipment, Japanese steel pipe company Fukuyama Plant and Mitsubishi Heavy Industries jointly developed a dry blast gas recovery system using dry high-pressure electrostatic precipitators, In May 1985, the world’s first practical device was put into operation at Fukuyama No.2 blast furnace. This article describes the operation of experimental and practical devices. 1. Small-scale semi-industrial test (1) the purpose of the test. First, to confirm the effect of heat storage buffer, the design of the formula and blast furnace dust on it (plug, wear, etc.); second is to verify the dry electrostatic dust collection performance and high temperature and pressure equipment safety and Dust of the way. (2) test equipment. Mainly by the heat storage buffer and dry electrostatic precipitator composition. Test regenerator buffer diameter of 1m, regenerator with hot blast furnace lattice brick masonry, 9m high.
