Description
技术领域 technical field
本发明是有关于一种转炉煤气干法除尘系统及其防爆装置。The invention relates to a converter gas dry dust removal system and an explosion-proof device thereof.
背景技术 Background technique
如图1所示，炼钢过程中氧枪吹入的氧与铁水中的碳在转炉19’内反应后生成富含CO的烟气，烟气经过汽化冷却烟道11’冷却后进入蒸发冷却器12’进行直接冷却，然后以160℃～220℃的温度从蒸发冷却器12’排出，经由烟气管道进入静电除尘器13’除去粉尘；被除尘的烟气在引风机14’的作用下，通过切换站15’对进入放散烟囱16’或煤气柜17’间烟气进行快速切换，在脱碳期间，高热值的烟气经过煤气冷却器18’冷却后被送到煤气柜17’，而在吹氧初期和末期产生的低热值烟气则被送到放散烟囱16’烧掉。在停止吹氧期间，烟气也同样经由放散烟囱16’排放。As shown in Figure 1, during the steelmaking process, the oxygen injected by the oxygen lance reacts with the carbon in the molten iron in the converter 19' to generate CO-rich flue gas. The cooler 12' is directly cooled, and then discharged from the evaporative cooler 12' at a temperature of 160°C to 220°C, and enters the electrostatic precipitator 13' through the flue gas pipeline to remove dust; the dust removed flue gas is under the action of the induced draft fan 14' , through the switching station 15', the flue gas entering the chimney 16' or the gas cabinet 17' is quickly switched. During the decarbonization period, the flue gas with high calorific value is cooled by the gas cooler 18' and then sent to the gas cabinet 17'. And the flue gas with low calorific value produced in the initial and final stages of oxygen blowing is sent to the chimney 16' for burning. During the stop of oxygen blowing, the flue gas is also discharged through the release chimney 16'.
转炉操作的间断性以及特定的冶炼周期使得空气、废气(含CO2)和转炉煤气(含CO)交替流过电除尘器和整个烟气净化系统。为了避免不同成分的气体被混合而发生突然燃烧(爆炸)，根据流体力学的原理，设计成圆筒形的电除尘器能为气体的流动提供最佳的通道，使不同成分的气体呈柱塞状流动而不被混合，从而消除气体发生突然燃烧(爆炸)的诱发因素。电除尘器外壳进出口两端设卸爆阀，当发生突然燃烧(爆炸)引起压力波动时，卸爆阀及时地进行卸压，保护电除尘器。The discontinuity of the converter operation and the specific smelting cycle make air, waste gas (containing CO 2 ) and converter gas (containing CO) alternately flow through the electrostatic precipitator and the entire flue gas cleaning system. In order to avoid the sudden combustion (explosion) of gases with different components being mixed, according to the principle of fluid mechanics, the cylindrical electrostatic precipitator designed can provide the best channel for the flow of gas, so that the gases of different components are in the form of a plunger. The gas flows without being mixed, thereby eliminating the predisposing factors for sudden combustion (explosion) of the gas. Explosion relief valves are installed at both ends of the shell of the electrostatic precipitator. When pressure fluctuations are caused by sudden combustion (explosion), the explosion relief valves will release the pressure in time to protect the electrostatic precipitator.
尽管如此，经验表明，电除尘器卸爆阀的质量或管理问题，存在卸爆过程中对除尘器内极板、极线定位的振动影响，同时因卸爆时要中断吹氧，影响转炉的正常工作。因此，爆炸问题一直制约转炉煤气干式除尘的发展，很多业主也将爆炸率作为一项非常重要的考核指标。Nevertheless, experience has shown that the quality or management of the explosion relief valve of the electrostatic precipitator has vibration effects on the positioning of the pole plate and polar line in the dust collector during the explosion relief process, and at the same time, the oxygen blowing must be interrupted during the explosion discharge, which affects the converter. normal work. Therefore, the explosion problem has always restricted the development of converter gas dry dust removal, and many owners also regard the explosion rate as a very important assessment index.
因此，需要研究并开发出一种变被动卸爆为主动的防爆装置。Therefore, it is necessary to study and develop an explosion-proof device that changes passive detonation into active one.
