When the lime powder unloading and mixing equipment is in operation, there will be a large number of dust drifting and dusting problems. These lime dusts have a great impact on the production environment. So how to deal with the dust of the lime powder unloading and mixing equipment?
How to deal with the dust of the lime powder discharge mixing equipment? In response to this problem, we have adopted a pulse bag filter for treatment. The treatment plan is as follows:
脉冲布袋除尘器运行方法，石灰粉尘在除尘系统中停留的时间越短 , 那么石灰粉尘发生化学变化形成粘结物堵塞管道、滤料的可能性越小 . 为此 , 必须制订一套行之有效的操作规程 , 即 : 先启动除尘系统风机 , 后启动工艺设备 ; 工艺设备停机后 , 除尘系统至少再运行半小时——除尘系统风机运行 15 分钟 , 袋式除尘器清灰装置运行 20 分钟 , 脉冲布袋除尘器和旋风除尘器下灰阀运行半小时 . 以上控制要求用电气联动或微机控制实现 . 1.The operation method of the pulse bag filter, the shorter the time that the lime dust stays in the dust removal system, the less likely it is that the lime dust will chemically change to form a bond to block the pipeline and filter material . To this end , a set of rules must be formulated . The effective operating procedures are as follows: first start the dust removal system fan and then start the process equipment ; after the process equipment is stopped , the dust removal system runs for at least half an hour-the dust removal system fan runs for 15 minutes , and the bag type dust collector ash cleaning device runs for 20 minutes The ash valve under the pulse bag dust collector and cyclone dust collector runs for half an hour . The above control requirements are realized by electric linkage or microcomputer control .
脉冲布袋除尘器讲究除尘管道设计 : 除尘系统的管网管道设计应尽可能作到减少或避免石灰粉尘沉降、停滞可能 , 做到少异形件 ( 三通、弯头 ) 、少涡流 , 选择合理风速 ( >16m/s); 并使除尘风管内呈速度递增状态 2.Pulse bag dust collector pays attention to the design of dust removal pipeline : The design of the pipeline network of the dust removal system should be as much as possible to reduce or avoid the possibility of lime dust sedimentation and stagnation , so as to reduce the number of irregular parts ( tees, elbows ) and eddy currents . Reasonable wind speed (> 16m / s); and increase the speed of the dust removal duct
石灰粉脉冲布袋除尘器设置安全旁路管道 : 当空气相对湿度增高时 , 进入除尘系统的含尘空气很易结露 , 为避免水气进入袋式除尘器粘结滤料 , 应设置安全旁路管道 , 此时可避开布袋收尘器 , 让含尘空气只通过第一级旋风除尘器 , 然后排入大气 . 以上可采用自动控制 . 3.The lime powder pulse bag filter is equipped with a safety bypass pipe : When the relative humidity of the air increases , the dust-laden air entering the dust removal system is easy to condense . In order to prevent water and gas from entering the bag filter's bonding filter , it should be set up safely. Bypass the pipeline , at this time, you can avoid the bag dust collector , and let the dust-containing air only pass through the first stage cyclone dust collector , and then discharged into the atmosphere . The above can be automatically controlled .
定期清洗除尘系统 : 一月或两月对整个除尘系统清洗一次 . 对除尘管道 , 可采取开启旁路安全管道 , 提高管道内风速来清洗 ; 对于袋式除尘器 , 可开动反吹风装置清灰装置、下灰阀进行清洗 . 4.Clean the dust removal system regularly: Clean the entire dust removal system once a month or two . For the dust removal pipeline , you can open the bypass safety pipeline to increase the wind speed in the pipeline to clean it ; for the bag type dust collector , you can start the anti-blowing device to clean it. Ash device and lower ash valve for cleaning .
注意尘源控制罩设计 : 不能把尘源控制罩当成粉尘接收容器 , 应该设计成既能很好控制尘源不让粉尘外逸 , 又尽可能少地吸走粉尘 , 以减轻除尘系统负担 . 5. Pay attention to the design of the dust source control hood : the dust source control hood cannot be used as a dust receiving container , it should be designed to control the dust source well to prevent dust from escaping , and to absorb dust as little as possible to reduce the burden on the dust removal system. .
How to deal with the dust of the lime powder discharge mixing equipment? Pulse bag filter operation principle:
The gas with lime powder discharge dust enters the filter box from the air inlet of the bag pulse dust collector, and is guided by the ash guide device. Large particles of lime powder discharge dust fall directly due to its own gravity. In the ash hopper, the fine lime powder discharge dust is sucked into the middle box and is adsorbed and isolated on the outer surface of the filter bag. The clean gas flows through the center of the filter bag to the upper box and passes through the fan and muffler. The exhaust pipe is discharged into the atmosphere. With the continuous operation of the bag pulse dust collector, the lime powder discharge dust on the filter bag is more and more. At this time, the pulse spraying system is automatically turned on to spray the filter bag. The compressed air is blown instantly to make the inside of the filter bag The pressure builds up, and the dust on the filter bag is sprayed into the ash hopper, and finally discharged from the ash discharge system.
