技术领域Technical Field
本发明涉及环保设备技术领域，具体的说是一种氧化钼回转窑用除尘结构。The invention relates to the technical field of environmental protection equipment, in particular to a dust removal structure for a molybdenum oxide rotary kiln.
背景技术Background Art
氧化钼回转窑用的除尘结构通常采用布袋除尘器，其能够将含尘气体由进气口进入除尘器，较大的粉尘颗粒由于重力作用直接落入灰斗，较细小的粉尘随气流上升通过滤袋时，粉尘被阻留在滤袋外表面，净化后的气体经出气口排出，也能去除各种粒径的粉尘，对细微粉尘也有很好的收集效果，减少粉尘对环境和人体健康的危害，还能在工业生产中起到回收有价值粉尘物质的作用，具有一定的经济价值，确保生产过程的清洁和安全，避免粉尘积聚引发的安全隐患。The dust removal structure used in molybdenum oxide rotary kiln usually adopts bag dust collector, which can let dust-containing gas enter the dust collector from the air inlet. Large dust particles fall directly into the ash hopper due to gravity. When the finer dust rises with the air flow through the filter bag, the dust is retained on the outer surface of the filter bag. The purified gas is discharged through the air outlet. It can also remove dust of various particle sizes and has a good collection effect on fine dust, reducing the harm of dust to the environment and human health. It can also play a role in recovering valuable dust substances in industrial production. It has certain economic value, ensures the cleanliness and safety of the production process, and avoids safety hazards caused by dust accumulation.
公开号为CN108465306B的中国专利，该发明公开了一种袋式除尘器，该袋式除尘器包括除尘室，净化室，灰斗，以及支腿。除尘室与净化室之间设置有第一隔板，除尘室与灰斗之间设置有第二隔板，第一隔板上开设有若干第一通孔，第二隔板上开设有若干第二通孔；每个第一通孔和对应的第二通孔之间分别固定有一根直管，每根直管的管壁上开设有若干列通风孔；每根直管中分别设置有一个骨架，每个骨架上分别套有一个滤袋；所述除尘室的侧壁开设有进风口，净化室的顶部开设有出风口，灰斗的底部设置有卸灰阀。本发明提供的袋式除尘器实现了含尘气流进入除尘室后不会影响到灰斗，不会对灰斗中原本沉积的灰尘避免造成“二次扬尘”。The Chinese patent with publication number CN108465306B discloses a bag dust collector, which includes a dust removal chamber, a purification chamber, an ash hopper, and a support leg. A first partition is provided between the dust removal chamber and the purification chamber, and a second partition is provided between the dust removal chamber and the ash hopper. The first partition is provided with a plurality of first through holes, and the second partition is provided with a plurality of second through holes; a straight tube is fixed between each first through hole and the corresponding second through hole, and a plurality of rows of ventilation holes are provided on the tube wall of each straight tube; a frame is provided in each straight tube, and a filter bag is sleeved on each frame; an air inlet is provided on the side wall of the dust removal chamber, an air outlet is provided on the top of the purification chamber, and an ash discharge valve is provided at the bottom of the ash hopper. The bag dust collector provided by the present invention realizes that the dust-laden airflow will not affect the ash hopper after entering the dust removal chamber, and will not cause "secondary dust" to the dust originally deposited in the ash hopper.
现有的袋式除尘器的除尘室与灰斗是完全相通的，如此一来，当含尘空气进入到除尘室时，便会扬起灰斗三侧中的灰尘，从而引发“二次扬尘”现象，而这些扬尘会再度被吹向滤袋，会降低除尘效率，增加除尘的工作时间。为防止出现扬尘情况，一般会选择改变除尘器的结构，例如增加除尘室的高度使得让气流在进入除尘室后与灰斗保持一定的距离，或者是将除尘室和灰斗进行一定程度的隔断，虽然能够降低“二次扬尘”造成的影响，但是会导致单位时间内通过除尘器的气体流量降低，大幅降低除尘效率，若灰斗底部发生堵塞，还需要人工进行疏通，降低了安全性。The dust chamber and ash hopper of the existing bag filter are completely connected. As a result, when the dust-laden air enters the dust chamber, the dust on the three sides of the ash hopper will be lifted, causing the phenomenon of "secondary dusting". The dust will be blown to the filter bag again, which will reduce the dust removal efficiency and increase the working time of dust removal. In order to prevent dusting, the structure of the dust collector is generally changed, such as increasing the height of the dust chamber so that the airflow keeps a certain distance from the ash hopper after entering the dust chamber, or separating the dust chamber and the ash hopper to a certain extent. Although it can reduce the impact of "secondary dusting", it will cause the gas flow rate passing through the dust collector per unit time to decrease, greatly reducing the dust removal efficiency. If the bottom of the ash hopper is blocked, it needs to be cleared manually, which reduces safety.
因此需要一种氧化钼回转窑用除尘结构解决在降低“二次扬尘”造成的影响的同时会导致单位时间内通过除尘器的气体流量降低，大幅降低除尘效率和安全性低的问题。Therefore, a dust removal structure for a molybdenum oxide rotary kiln is needed to solve the problem that while reducing the impact of "secondary dust", the gas flow through the dust collector per unit time is reduced, which greatly reduces the dust removal efficiency and low safety.

具体的，布袋除尘器主体1的一侧安装有排气装置主体5，灰斗2的底部安装有支架6，灰斗2的一侧安装有观察门22，灰斗2的与安装有观察门22一侧相邻的一侧贯穿安装有进风口21。Specifically, an exhaust device body 5 is installed on one side of the bag filter body 1, a bracket 6 is installed at the bottom of the ash hopper 2, an observation door 22 is installed on one side of the ash hopper 2, and an air inlet 21 is installed through the side of the ash hopper 2 adjacent to the side where the observation door 22 is installed.
在本实施例中，当含尘气体进入布袋除尘器主体1后，颗粒大、比重大的粉尘由于重力的作用沉降下来，落入灰斗2，含有较细小粉尘的气体在通过滤料时，粉尘被阻留，使气体得到净化，滤袋由纤维编织而成，具有很多细小的孔，气体可以通过这些孔，而粉尘则被截留在滤袋表面，随着过滤的进行，滤袋表面的粉尘不断积累，形成粉尘层，进一步增强了过滤效果。当粉尘层达到一定厚度时，通过清灰装置将粉尘清除，使滤袋恢复过滤能力，观察门22用于观察灰斗2内部情况，安装此除尘装置时，工作人员根据实际情况选择合适的电机，并将其与排灰转杆23相连接，为整个排灰过程提供给动力，再将废气管道与进气口相连接，然后将回收器皿安装于灰斗2底部，便于回收灰尘。In this embodiment, after the dust-laden gas enters the bag filter body 1, the dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper 2.

The gas can pass through these holes, and the dust is trapped on the surface of the filter bag. As the filtration proceeds, the dust on the surface of the filter bag accumulates continuously to form a dust layer, which further enhances the filtration effect. When the dust layer reaches a certain thickness, the dust is removed by the dust cleaning device to restore the filtering capacity of the filter bag. The observation door 22 is used to observe the internal situation of the ash hopper 2. When installing this dust removal device, the staff selects a suitable motor according to the actual situation and connects it to the ash discharge rotating rod 23 to provide power for the entire ash discharge process.
