环保喷漆房的防爆措施如何做?

How to do the explosion-proof measures of environmental protection spray booth?

选用性能、叶片安全系数高的离心风机,要符合行业标准要求,采用电机外置风机,让电机放置在风道外,可以有效避免电气方面的安全隐患,防止叶片上漆雾堆积。

The centrifugal fan with high performance and blade safety factor should meet the requirements of the industry standard. The external fan of the motor should be used, and the motor should be placed outside the air duct, which can effectively avoid the potential electrical safety hazards and prevent the accumulation of paint mist on the blade.

在排风系统中增加水喷淋除漆雾装置,该装置在排风前增加水洗装置,采用多级水喷淋,使通过干式过滤材料的细小颗粒进一步被搜集,此种方式和湿式喷漆室的漆雾净化方式相类似,可以避免风机及风管内的积累漆,减少爆炸火灾发生的概率。

A water spray mist eliminator is added to the exhaust system. A water washing device is added to the device before the exhaust. The multi-stage water spray is used to further collect the fine particles passing through the dry filter material. This method is similar to the paint mist purification method of the wet spray booth, which can avoid the accumulation of paint in the fan and air duct, and reduce the probability of explosion and fire.

定期对柴油滤芯进行换新(每8-12个月一次),对高压油泵过滤网要6个月清洁一次,对高压喷嘴过滤网一年清洁一次。

Regularly renew the diesel filter element (every 8-12 months), clean the filter screen of high-pressure oil pump once every 6 months, and clean the filter screen of high-pressure nozzle once a year.

               

以上是关于喷漆烤漆房的介绍,而且使用的柴油牌号必须高于当地夜间极低气温5度,不得使用回笼油、有水或其他杂质的柴油。

The above is about the introduction of spray painting and baking room, and the brand of diesel oil used must be 5 degrees higher than the local extremely low temperature at night. It is not allowed to use recycled oil, water or other impurities of diesel oil.

环保烤漆房不能使用破损的布袋进行工作,否则会加速除尘器的报废。当个别布袋发生小面积破损时,可以用旧的布袋或同样材料新滤布将破洞补上使用,补洞方法是使用有机硅橡胶混合料进行粘接,只要粘接剂的使用温度、化学性能与工艺状况相适应便可。

The environmental protection paint baking room can not use the damaged cloth bag to work, otherwise it will accelerate the scrapping of the dust collector. When some cloth bags are damaged in a small area, the holes can be filled with old cloth bags or new filter cloth of the same material. The hole filling method is to use silicone rubber mixture for bonding, as long as the temperature and chemical properties of the adhesive are suitable for the process conditions.

环保烤漆房是逐渐磨损的,引起磨损的主要原因是粉尘的磨削力,高温引起的滤料变质和化学物质的腐蚀,当粉尘的磨削力很强时,布袋底部磨损严重,系统容量的增加引起过滤速度增高也能加速磨损。

The environment-friendly paint baking room is gradually worn. The main causes of wear are the grinding force of dust, the deterioration of filter material and the corrosion of chemical substances caused by high temperature. When the grinding force of dust is very strong, the bottom of the bag is seriously worn, and the increase of system capacity causes the increase of filtration speed, which can also accelerate the wear.

当大部分布袋损坏时,应进行全部更换(当滤料在长期工作以后,滤料层内积聚的微细粉尘使其透气性降低,而影响系统风量时,虽未损坏,也应进行全部更换),更换布袋在除尘器停止工作时进行,此时应将清灰控制器关闭,打开顶部的入孔门,便可拆卸布袋,拆卸时,先将袋笼取出,然后将布袋上口的弹簧圈捏成凹形,向上拉出布袋,安装新布袋前,应将花板孔上的粉尘清理干净。

When most of the bags are damaged, they should be replaced completely (when the fine dust accumulated in the filter layer reduces the air permeability after long-term operation of the filter material and affects the air volume of the system, they should be replaced completely even though they are not damaged). The replacement of the bags should be carried out when the dust collector stops working. At this time, the dust removal controller should be closed and the inlet door at the top should be opened to remove the bags, When disassembling, take out the bag cage first, then pinch the spring ring at the upper opening of the cloth bag into a concave shape, pull out the cloth bag upward, and clean the dust on the hole of the pattern plate before installing a new cloth bag.
