工作原理

working principle

含塵氣體由位于除塵器上部的進風口進入除塵器箱體，由上下行，由于重力與下行氣流的作用首先把塵粒直接降至灰斗，細粉塵被濾筒捕集在外表面，潔凈氣體經(jīng)濾筒過濾凈化后，由濾筒中心進入清潔室，再經(jīng)下出風口排出。隨著過濾工況持續(xù)，聚集在濾筒表面的粉塵增多，此時脈沖控制儀按設定的脈沖周期和脈沖間隔控制電磁閥開啟，噴出高壓氣體，吹入濾筒內腔，抖落外表積塵，落入灰斗，經(jīng)卸灰口排出。

Dust containing gas enters the dust collector box from the air inlet located at the upper part of the dust collector, and from top to bottom. Due to the effect of gravity and downward airflow, the dust particles are first directly lowered into the ash hopper, and fine dust is captured on the outer surface by the filter cartridge. After the clean gas is filtered and purified by the filter cartridge, it enters the clean room from the center of the filter cartridge and is then discharged through the lower air outlet. As the filtering condition continues, the dust that accumulates on the surface of the filter cartridge increases. At this time, the pulse control instrument controls the solenoid valve to open according to the set pulse cycle and pulse interval, spraying high-pressure gas into the inner chamber of the filter cartridge, shaking off the dust on the surface, and falling into the ash hopper, which is discharged through the ash discharge port.

焊煙集中收集濾筒除塵器濾材的清潔通過由壓差傳感器控制的脈沖噴吹機構實現(xiàn)：當凈化器運行一段時間以后，細微的煙塵吸附在濾材表面，使得濾材的透氣性降低。壓差傳感器的兩個探測頭一個安裝在原氣側、一個安裝在凈氣側。當壓差傳感器檢測到的壓差超過某一設定值時輸出壓差信號，脈沖發(fā)生器接收信號后順序啟動脈沖噴吹閥，潔凈的壓縮空氣由閥口噴出，引射氣流對濾筒進行吹掃直到壓差低于另一設定值時才停止；濾材表面吸附的微塵在氣流作用下被清除，落在室體下部的集塵斗中。脈沖噴吹需0.5～0.6MPa的潔凈壓縮空氣，且運行中須保持連續(xù)且恒定不變的供氣量。濾筒式過濾器與傳統(tǒng)靜電式過濾器、機械式過濾器相比有如下優(yōu)點：排放濃度低，達5mg/m3,一般其他過濾器只能過濾0.5um以上粒徑;而我司產(chǎn)品能過濾0.3um以上的粉塵。透氣性好，氣阻比一般過濾器低;清灰方便，全自動清灰，保證生產(chǎn)的連續(xù)性和高效性。粉塵收集，容器裝卸便捷，與過濾漏斗的連接是密封的，不漏灰塵。

The cleaning of the filter material of the welding smoke centralized collection filter cartridge dust collector is achieved through a pulse blowing mechanism controlled by a pressure difference sensor. After the purifier runs for a period of time, fine smoke and dust adsorb on the surface of the filter material, reducing its breathability. The two detection heads of the pressure difference sensor are installed on the raw gas side and one on the clean gas side. When the pressure difference detected by the pressure difference sensor exceeds a certain set value, a pressure difference signal is output. After receiving the signal, the pulse generator sequentially starts the pulse blowing valve, and clean compressed air is sprayed out from the valve port. The injected airflow blows the filter cartridge until the pressure difference is lower than another set value before stopping; The fine dust adsorbed on the surface of the filter material is removed by the airflow and falls into the dust collection hopper at the lower part of the chamber. Pulse injection requires clean compressed air of 0.5~0.6MPa and a continuous and constant air supply during operation. Compared with traditional electrostatic and mechanical filters, cartridge filters have the following advantages: low emission concentration, up to 5mg/m3, and generally other filters can only filter particles with a diameter of more than 0.5um; And our product can filter dust above 0.3um. Good breathability, lower air resistance than ordinary filters; Convenient ash cleaning, fully automatic ash cleaning, ensuring continuous and efficient production. Dust collection, convenient container loading and unloading, and sealed connection with the filter funnel to prevent dust leakage.

焊煙集中收集濾筒除塵器過濾濾材特點

Characteristics of Filter Materials for Welding Smoke Centralized Collection Filter Cartridge Dust Remover

焊煙集中收集濾筒除塵器采用高效過濾筒作為過濾元件，該過濾筒選用的濾材不同于一般傳統(tǒng)的濾材，其表面附有一層聚四氟乙烯薄膜。傳統(tǒng)濾材（如棉布、棉緞、紙質及其他傳統(tǒng)纖維素等）纖維間隙為5～60um，當煙塵通過時，煙塵中的一部分塵粒就會進入濾材內部而阻塞過濾元件；當阻塞情況逐漸惡化又不能進行有效清灰時，過濾元件的氣阻便會上升，能通過的氣流量也會隨之下降。如果沒有自動清灰，過濾效果會迅速下降，而該系列凈化器采用的濾材表面附有一層聚四氟乙烯薄膜，其極小的篩孔可阻擋大部分亞微米塵粒；亞微米塵粒在濾材的表面聚集并形成可滲透的擋塵餅，大部分塵粒被阻擋在濾材外表面而不能進入濾材內部，在壓縮空氣的吹掃下能及時有效地被清除。該濾材具有相當高的過濾效率，較傳統(tǒng)濾材至少提高3～5倍以上；且使用壽命較傳統(tǒng)濾材提高2倍以上

The welding smoke centralized collection filter cartridge dust collector uses an efficient filter cartridge as the filtering element. The filter cartridge uses a different filter material from traditional filters, with a layer of polytetrafluoroethylene film attached to its surface. Traditional filter materials (such as cotton cloth, cotton satin, paper, and other traditional cellulose) have a fiber gap of 5-60um. When smoke passes through, a portion of the dust particles in the smoke will enter the filter material and block the filter element; When the blockage situation gradually deteriorates and effective ash removal cannot be carried out, the air resistance of the filtering element will increase, and the air flow rate that can pass through will also decrease. If there is no automatic dust removal, the filtering effect will rapidly decrease, and the filter material used in this series of purifiers has a layer of polytetrafluoroethylene film attached to its surface, which has extremely small sieve holes that can block most of the submicron dust particles; Submicron dust particles gather on the surface of the filter material and form permeable dust blocking cakes. Most of the dust particles are blocked on the outer surface of the filter material and cannot enter the interior of the filter material. They can be timely and effectively removed under the blowing of compressed air. This filter material has a relatively high filtration efficiency, which is at least 3-5 times higher than traditional filter materials; And the service life is more than twice that of traditional filter materials
