倉頂除塵器用于水泥倉、料倉、灰庫、攪拌站等設備的上方收集倉內的揚塵，把揚塵中的空氣與粉塵進行過濾分離。

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.

倉頂除塵器是由脈沖裝置、過濾裝置、箱體、排放裝置組成的一種無灰斗的干燥過濾凈化除塵器，揚塵凈化效率達到90%以上，具有結構合理、運行穩定、使用壽命長、凈化效率好的優點。

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.

倉頂除塵器工作原理

Working principle of warehouse top dust collector

倉頂除塵器把揚塵吸入箱體底部，通過濾袋進行過濾，過濾后的空氣被風機排向室外，而粉塵則被濾袋截留，當粉塵在濾袋外表面形成粉層后，定時抖動濾讓表面的粉層降落在除塵器下方的料倉內。

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.

倉頂除塵器的生產是依據水泥、石灰、粉煤灰等各種物料的特性、揚塵特點、安裝環境，并結合公司長時間除塵設計經驗制作，廣泛應用于攪拌站倉頂、破碎粉料倉頂、水泥粉磨站倉頂、灰庫倉頂的揚塵治理。

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.

倉頂除塵器工作時，含塵氣體由下部敞開式法蘭進入過濾室，較粗顆粒直接落入灰倉，含塵氣體經濾袋過濾，粉塵阻留于袋表，凈氣經袋口到凈氣室，由風機排入大氣。當濾袋外表的粉塵不時增加，除塵控制儀開啟工作，逐一開啟脈沖閥，使緊縮空氣經過噴口對濾袋停止噴吹清灰，使濾袋忽然收縮，在反向氣流的作用下，賦予袋表的粉塵疾速脫離濾袋落入灰倉，粉塵由卸灰閥排出。利用高速噴射氣流通過濾袋頂時，吹向濾袋內部，形成空氣波，使濾袋由上向下產生急劇的膨脹和沖擊振動，產生有力的的清落粉塵的作用。脈沖清灰作用較強，清灰效果較好，可提高過濾風速。脈沖清灰是目前清灰效果比較好的清灰方式。

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.
