为了更有效地把热处理生产过程中产生的大量有毒气体、油烟和酸、碱气体排出室外,我们对排烟系统作了如下的改进,排烟效果显著。一、采用地道和侧风口排烟:国内许多工厂仍采用管道式抽风,少数工厂还采用罩式抽风法,这两种排烟装置的管道和钟罩占地面积和空间体积大,制造困难,需耗用大量的钢板,管道易腐蚀,同时增加了维修工作量,而且工作场地不紧凑,影响操作。我们从1971年开始采用地道和侧吸风口排烟。地道用砖砌,表面用水泥
In order to effectively exhaust a large amount of toxic gases, fumes and acid and alkali gases generated during the heat treatment process to the outdoors, we made the following improvements to the smoke exhaust system, and the smoke exhaust effect is remarkable. First, the use of authentic and side vents Smoke: Many domestic factories still use pipe-type exhaust, a few factories also use the hood exhaust method, the two exhaust pipe and bell housing area and space volume, manufacturing difficulties, Requires a lot of steel, pipe corrosion, while increasing the workload of maintenance, and the workplace is not compact, affecting the operation. We started with authentic and side suction exhaust smoke since 1971. Authentic brick, surface with cement
