本文叙述我厂近几年来在布袋除尘方面所进行的若干改进:①煤气温度的调节控制。采取把布袋箱体系列中的第一个箱体改作换热器,即把该箱体内布袋换成钢管,半荒煤气走管内,调温气体走管外;②采用闭路调压反吹方式。为此先后把两座高炉的炉顶大小料钟均以半刚性连接取代自由下降的钢丝绳传动方式,其次自行设计制作了一个煤气调压装置;③布袋箱体卸灰及灰尘水力输送;④改进安全保障措施。把螺栓紧固改为楔子紧固;箱体上方的防爆孔改用重砣式;尽量保持箱体集灰斗内壁光滑。
This article describes the plant in recent years in the bag dust removal carried out by a number of improvements: ① gas temperature control. Take the first box in the bag box series as a heat exchanger, that is, the bag inside the box replaced by steel pipe, half-gas-go tube, the temperature control gas outside the tube; ② closed-circuit pressure blowback mode. To this end has two furnace blast furnace roof bell size are semi-rigid connection instead of free-fall wire rope transmission, followed by a gas-pressure control device designed and manufactured; ③ bag box dust and dust hydraulic transmission; ④ improve Security measures. The bolt fastening to wedge fastening; explosion-proof box above the box to use heavy 砣 style; try to keep the box set ash bucket wall smooth.
