Code for leak detection of phosphor dust in bag filter

2019-08-05 10:48:08 AM

标。 Phosphor leak detection is generally performed after a new installation of the bag, or when the smoke and dust emissions exceed the standard, in order to detect the leakage point and ensure the emission standard. 20min 左右,以提高检测准确性。 If the used dust collector is checked, turn on the dust removal system and clean the dust for about 20 minutes to improve the detection accuracy. 况并结合该除尘器的特点我们拟定如下检测方案,以帮助检测漏灰的确切位置。 In view of this situation and combining the characteristics of the dust collector, we have developed the following detection scheme to help detect the exact location of ash leakage. 1 、停机清理净气室的灰尘及物料,以免其干扰判断; 2 、开始投粉前 , 将清灰系统打开清灰 10-20min 左右; 3 、自备检漏专用荧光粉、检漏专用荧光灯、滤光眼镜和记号笔。 Preparations before leak detection: 1. Stop and clean the dust and materials in the clean room to avoid interference with judgment; 2. Before turning on the powder , turn on the dust cleaning system for about 10-20min ; 3. Prepare your own leak detection Fluorescent powder, leak detection fluorescent lamp, filter glasses and marker pen. 请按以下操作要求为指南,进行检漏操作,如运行现场情况有所变化,请根据实际情况予以调整: 1 、在清灰系统停止运行的条件下 , 引风机 60% 以上开度运行(以能够将荧光粉吸入不致掉入灰斗为标 准),将荧光粉投入除尘器的进风管道的开口处; 2 、荧光粉的投入口位置应距离除尘器进风口约 6m 以外为合适,否则应考虑将荧光粉从除尘器的灰 斗出口或灰斗检修门处投入(应在布袋除尘器前投入,如有旋风除尘器则应在旋风除尘器之后投入); 3 、从喂入口添加荧光粉时不需要特殊的设备,不过投料时间不宜太久,只需要正常将荧光粉倒入喂 入口即可,不可一下整桶倒入,以免沉降;一般 50 公斤的荧光粉控制在 3~5 分钟左右; 4 、荧光粉添加完成后,引风机在 10 分钟左右时间内停机 5 、约过半小时后 , 开打开净气室; 6 、荧光粉投入完毕 Leak detection operation steps: Please follow the following operating requirements as a guide for leak detection operations. If the operation site conditions change, please adjust according to the actual situation: 1. When the dust removal system stops running , the induced fan 60% The above opening operation (based on being able to inhale the phosphor powder and not fall into the ash hopper ), put the phosphor powder into the opening of the air inlet duct of the dust collector; 2. The position of the phosphor powder inlet should be about the distance from the dust inlet of the dust collector. It is suitable to be more than 6m , otherwise, phosphor powder should be considered to be input from the dust bucket outlet or dust bucket maintenance door of the dust collector (it should be put in front of the bag dust collector, if there is a cyclone dust collector, it should be put in after the cyclone dust collector); 5. No special equipment is needed when adding phosphor from the feed inlet, but the feeding time should not be too long. You only need to pour the phosphor into the feed inlet normally . Do not pour the whole barrel to avoid sedimentation; generally 50 kg of phosphor Controlled in about 3 ~ 5 minutes; 4. After the phosphor is added, the induced fan will stop in about 10 minutes. 5. After about half an hour , open and open the clean air chamber. 6. The phosphor is put in 接缝处,布袋与花板的接口点等;检测时,周围环境亮度越暗越有助于泄漏检测工作的进行,因此晚 上做荧光粉检漏效果最好; 7 、分析原则 : 如果在净气室某一位置发现有发亮的粉状物 , 则说明附近有漏点 , 应注意查看粉状物的位 置分布数量及走向 , 并用记号笔作标记; 8 、观察重点位置:除尘器四壁、钢板焊接处和布袋口四周; 9 、如发现问题 , 应标记清楚 , 并及时处理,避免二次污染; 10 、注意:人员进除尘器前检查身体不得沾染荧光粉,以免干扰判断。 After that, turn off the main fan and open the top cover of the dust collector. Use fluorescent lights to carefully inspect the joints of the flower panel in the clean room , the interface point between the bag and the flower panel. When testing, the darker the surrounding environment, the more helpful it is. Leak detection is performed, so fluorescent powder leak detection is the best at night . 7. Analysis principle : If a bright powder is found at a certain position in the clean room , there are leaks nearby , you should pay attention to check The position and quantity of the powder are distributed and marked with a marker; 8. Observation points: the four walls of the dust collector, the welded steel plate and the bag opening; 9. If problems are found , they should be clearly marked and dealt with in a timely manner. Avoid secondary pollution; 10. Attention: before entering the dust collector, check that the body is not contaminated with fluorescent powder, so as not to interfere with the judgment. 2 人分别担任。 It is suggested that two persons should be employed as the person who casts the powder and the person who checks the leaks . 、如果漏点较多,可以更换新布袋后采用绿色荧光粉做二次检漏。 11. If there are many leaks, you can replace the bag with a green phosphor for secondary leak detection. + 柯浩曼;手机: 15161666371 ;交流合作 QQ 379132676 Leak detection phosphor supplier: Xiamen Jiangliang + Ke Haoman ; Mobile phone: 15161666371 ; Exchange and cooperation QQ : 379132676 ;
