荧光增白剂厂家:荧光粉检漏原理
Fluorescent whitening agent manufacturer: fluorescent powder leak detection principle
零碎中的构造性空气走漏,如焊缝,金属封箱盖不密合等等成绩,除非成绩十分分明,否则不易被发现。传统反省时,任务人员必需长工夫表露在除尘器的恶劣环境中。此方案还可以普遍运用在管道测漏,各种气箱容器等设备的测漏任务。
Fragmentary structural air leakage, such as weld seam, metal seal cover is not tight and other achievements, unless the results are very clear, otherwise it is not easy to be found. In traditional introspection, mission personnel have to work long hours to expose themselves to the harsh environment of dust collectors. This scheme can also be widely used in pipeline leak detection, various gas tank containers and other equipment leak detection tasks.
1.在烟气进入除尘器前的小仓空孔直径至多8cm。假如检漏的是新除尘器或刚重新装置的过滤袋的除尘器,请间接进入步骤3。
1. The diameter of the empty hole in the small bin before the flue gas enters the dust collector is up to 8 cm. If the leak is detected by a new dust collector or or a filter bag that has just been re-equipped, please proceed indirectly to step 3.
2.假如反省的是运用过的除尘器,封闭在线清灰零碎以保证在滤袋外表构成灰尘饼,从而在布袋的内外两侧构成较高的压差。这能促使荧光粉穿过任何小洞。假如能够,视觉检查净气室在灰尘负载和除灰的压力,这样一来就不会掩盖住荧光粉,荧光粉可以将走漏点显现出来。
2. If we reflect on the used dust collector, we should close the online dust removal fragments to ensure that the dust cake is formed on the outside of the filter bag, thus forming a higher pressure difference on both sides of the bag. This allows the phosphor to pass through any small hole. If possible, visual inspection of the pressure of the air cleaner in the dust load and ash removal, so that the phosphor will not be covered up, phosphor can show the leak point.

3.翻开风机,并以0.5公斤/100平方米滤料的量注入荧光粉(在正压零碎只,应在风机前注入)。注入荧光粉的量有时还需思索风机到除尘器的管道间隔。
3. Turn on the fan and inject phosphor with the amount of 0.5 kg/100 square meters filter material (in the positive pressure of fragments, should be injected before the fan). The amount of phosphor injected sometimes requires consideration of the pipe spacing between the fan and the dust collector.
4.注入荧光粉后,风机要持续运转约45秒,但不善于1分钟。风机中止后,用灯反省。关于脉冲零碎,反省时要翻开顶门并用灯在净气室照射。留意:室外反省必需在黑暗中停止。关于振打和反吹风零碎,反省应该在外部停止。从下部开端,并集中在支撑板四周。
4. After injecting phosphor, the fan will run for about 45 seconds, but not better than 1 minute. After the fan stops, use the lamp to reflect. With regard to pulse fragmentation, the top door should be opened and illuminated in the air purification chamber with a lamp when introspecting. Note: Outdoor reflection must stop in the dark. With regard to beating and blowing, reflection should be stopped outside. Start from the bottom and concentrate around the support plate.
5.在有破损和洞的区域,荧光粉会穿过并进入净气室中,在UV灯下会收回荧光。这些荧光标识的区域就是走漏点。
5. In areas with breakage and holes, the phosphor will pass through and enter the clean air chamber, and the fluorescence will be recovered under the UV lamp. These fluorescent markers are the leak points.
6.当一切的维修颐养完成后,用另外一种颜色的荧光粉重新反省以确保没有走漏遗留。第二种颜色将会清楚地显示脱漏的走漏。当荧光粉被撒入袋除尘器中,它会飘向阻力比较小的中央,比较终聚积在走漏点的四周。只需用公用紫光灯照射就能随便地找到走漏点并清楚地晓得泄露水平。
6. When all the repairs and maintenance are completed, use another color of phosphor to rethink to ensure that there is no missing. The second color will clearly show leaks. When the phosphor is thrown into the bag filter, it will float to the center of the least resistance, and eventually accumulate around the leak point. The leak point can be found casually and the leak level can be clearly known just by illuminating with a public purple lamp.
