Negative pressure combined dust collector is an efficient dust removal equipment that combines multiple dust removal mechanisms and operates under negative pressure, commonly used for dust control in industrial production. Here is the relevant introduction:

工作原理

Working principle

組合除塵機理：它通常結(jié)合了重力沉降、慣性分離、離心分離、過濾等多種除塵方式。含塵氣體首先進(jìn)入除塵器的預(yù)收塵室，較大顆粒的粉塵在重力作用下自然沉降；隨后，氣體攜帶較小顆粒進(jìn)入旋風(fēng)除塵區(qū)域，利用離心力使粉塵與氣體分離；最后，經(jīng)過初步處理的氣體通過過濾裝置，如布袋或濾芯，將剩余的細(xì)微粉塵攔截下來，從而實現(xiàn)高效除塵。

Combination dust removal mechanism: It usually combines multiple dust removal methods such as gravity settling, inertial separation, centrifugal separation, and filtration. The dusty gas first enters the pre collection chamber of the dust collector, and larger particles of dust naturally settle under the action of gravity; Subsequently, the gas carries smaller particles into the cyclone dust removal area and uses centrifugal force to separate the dust from the gas; Finally, the gas that has undergone preliminary treatment is filtered through devices such as bags or filters to intercept the remaining fine dust, thereby achieving efficient dust removal.

負(fù)壓運行原理：通過引風(fēng)機產(chǎn)生負(fù)壓，使含塵氣體在負(fù)壓作用下進(jìn)入除塵器。這種負(fù)壓環(huán)境有助于提高除塵效率，防止粉塵外溢，保證工作環(huán)境的清潔。

Principle of negative pressure operation: Negative pressure is generated by the induced draft fan, allowing the dust containing gas to enter the dust collector under the action of negative pressure. This negative pressure environment helps to improve dust removal efficiency, prevent dust from overflowing, and ensure a clean working environment.

結(jié)構(gòu)組成

Structural composition

預(yù)收塵室：一般位于除塵器的入口處，是一個較大的空間，主要用于使含塵氣體中的大顆粒粉塵在重力作用下初步沉降，減輕后續(xù)除塵單元的負(fù)荷。

Pre dust collection room: usually located at the entrance of the dust collector, it is a large space mainly used to allow large particles of dust in the dusty gas to settle initially under the action of gravity, reducing the load on subsequent dust removal units.

旋風(fēng)除塵單元：由旋風(fēng)分離器組成，利用旋轉(zhuǎn)氣流產(chǎn)生的離心力使粉塵從氣流中分離出來。旋風(fēng)分離器通常有多個，以提高除塵效果。

Cyclone dust removal unit: composed of a cyclone separator, which uses the centrifugal force generated by the rotating airflow to separate dust from the airflow. There are usually multiple cyclone separators to improve dust removal efficiency.

過濾單元：采用布袋或濾芯等過濾材料，對經(jīng)過旋風(fēng)除塵后的氣體進(jìn)行進(jìn)一步過濾，攔截細(xì)微粉塵。過濾單元通常設(shè)計有清灰裝置，如脈沖噴吹系統(tǒng)，定期清除過濾材料表面的粉塵，以保證過濾效果和設(shè)備的正常運行。

Filtering unit: using filter materials such as bags or filter cartridges to further filter the gas after cyclone dust removal, intercepting fine dust. The filtering unit is usually designed with a dust cleaning device, such as a pulse blowing system, to regularly remove dust from the surface of the filtering material to ensure the filtering effect and normal operation of the equipment.

引風(fēng)機：位于除塵器的出口端，用于產(chǎn)生負(fù)壓，使含塵氣體能夠順利通過除塵器，并將凈化后的氣體排放到大氣中。

Induced draft fan: located at the outlet end of the dust collector, it is used to generate negative pressure, allowing the dust containing gas to pass through the dust collector smoothly and discharge the purified gas into the atmosphere.
