仓顶除尘器用于水泥仓、料仓、灰库、搅拌站等设备的上方收集仓内的扬尘，把扬尘中的空气与粉尘进行过滤分离。

The top dust collector is used above equipment such as cement silos, material silos, ash silos, and mixing plants to collect dust inside the silos, filtering and separating the air and dust in the dust.

仓顶除尘器是由脉冲装置、过滤装置、箱体、排放装置组成的一种无灰斗的干燥过滤净化除尘器，扬尘净化效率达到90%以上，具有结构合理、运行稳定、使用寿命长、净化效率好的优点。

The silo top dust collector is a dry filtering and purification dust collector without an ash hopper, composed of a pulse device, a filtering device, a box, and a discharge device. The dust purification efficiency reaches over 90%, and it has the advantages of reasonable structure, stable operation, long service life, and good purification efficiency.

仓顶除尘器工作原理

Working principle of warehouse top dust collector

仓顶除尘器把扬尘吸入箱体底部，通过滤袋进行过滤，过滤后的空气被风机排向室外，而粉尘则被滤袋截留，当粉尘在滤袋外表面形成粉层后，定时抖动滤让表面的粉层降落在除尘器下方的料仓内。

The top dust collector sucks the dust into the bottom of the box and filters it through a filter bag. The filtered air is discharged to the outside by the fan, and the dust is intercepted by the filter bag. When the dust forms a powder layer on the outer surface of the filter bag, it shakes and filters regularly to allow the surface powder layer to fall into the material bin below the dust collector.

仓顶除尘器的生产是依据水泥、石灰、粉煤灰等各种物料的特性、扬尘特点、安装环境，并结合公司长时间除尘设计经验制作，广泛应用于搅拌站仓顶、破碎粉料仓顶、水泥粉磨站仓顶、灰库仓顶的扬尘治理。

The production of silo top dust collectors is based on the characteristics of various materials such as cement, lime, fly ash, dust characteristics, installation environment, and combined with the company's long-term dust removal design experience. They are widely used in the dust control of mixing station silo tops, crushing powder silo tops, cement powder grinding station silo tops, and ash silo tops.

仓顶除尘器工作时，含尘气体由下部敞开式法兰进入过滤室，较粗颗粒直接落入灰仓，含尘气体经滤袋过滤，粉尘阻留于袋表，净气经袋口到净气室，由风机排入大气。当滤袋外表的粉尘不时增加，除尘控制仪开启工作，逐一开启脉冲阀，使紧缩空气经过喷口对滤袋停止喷吹清灰，使滤袋忽然收缩，在反向气流的作用下，赋予袋表的粉尘疾速脱离滤袋落入灰仓，粉尘由卸灰阀排出。利用高速喷射气流通过滤袋顶时，吹向滤袋内部，形成空气波，使滤袋由上向下产生急剧的膨胀和冲击振动，产生有力的的清落粉尘的作用。脉冲清灰作用较强，清灰效果较好，可提高过滤风速。脉冲清灰是目前清灰效果比较好的清灰方式。

When the top dust collector is working, the dusty gas enters the filter chamber through the open flange at the bottom, and the coarser particles directly fall into the ash bin. The dusty gas is filtered by the filter bag, and the dust is trapped on the bag surface. The clean gas is then transported to the clean gas chamber through the bag mouth and discharged into the atmosphere by a fan. When the dust on the surface of the filter bag increases from time to time, the dust removal control device starts working and opens the pulse valves one by one, causing compressed air to pass through the nozzle and stop spraying clean dust on the filter bag, causing the filter bag to suddenly shrink. Under the action of reverse airflow, the dust on the bag surface quickly separates from the filter bag and falls into the ash bin, and the dust is discharged by the ash discharge valve. When high-speed jet airflow passes through the top of the filter bag, it blows towards the inside of the filter bag, forming an air wave that causes the filter bag to rapidly expand and vibrate from top to bottom, producing a powerful effect on dust removal. The pulse cleaning effect is strong, and the cleaning effect is good, which can improve the filtering wind speed. Pulse cleaning is currently the most effective cleaning method for dust removal.
