The centralized welding smoke dust collector is mainly designed to control the large amount of harmful dust particles generated during production in industries such as mechanical processing, foundry, powder recycling, medical production, food processing, welding smoke, cutting, polishing, furniture production, etc. The processing air volume is 4000-6000m/ h. Different combinations meet the processing requirements of different air volumes and can meet the dust collection and treatment requirements of multiple processes in the production workshop. The collection methods include mobile suction arms and fixed collection covers, which reduce the escape of dust into the workshop and ensure the working environment of the workshop. It can purify a large number of dust particles suspended in the air that are harmful to the human body.

设备结构组成:

Equipment structure composition:

本除尘器主要由前端过滤、集尘主箱体、脉冲清灰、阻火网、收集灰斗、支脚框架、排灰装置、脉冲清灰系统组成。需防爆的工况，可加卸爆口；如需集成控制，可加PLC控制系统。

This dust collector mainly consists of front-end filtration, dust collection main box, pulse cleaning, fire screen, ash collection hopper, support frame, ash discharge device, and pulse cleaning system. Explosion proof working conditions can be equipped with explosion discharge ports; If integrated control is required, a PLC control system can be added.

工作原理:

Working principle:

本设备在系统主风机的作用下，含尘气体从除尘器下部或侧面的进风口进入除尘器的气箱内进行含尘气体的预处理，然后从底部进入到上箱体的各除尘室内；粉尘吸附在滤筒的外表面上，过滤后的干净气体透过滤筒进入上箱体的净气腔并汇集至出风口排出。

Under the action of the main fan of the system, the dust containing gas enters the air box of the dust collector from the lower or side air inlet for pre-treatment, and then enters each dust removal room of the upper box from the bottom; Dust is adsorbed on the outer surface of the filter cartridge, and the filtered clean gas enters the clean air chamber of the upper box through the filter cartridge and collects at the air outlet for discharge.

随着过滤工况持续，积聚在滤筒外表面上的粉尘将越积越多，相应就会增加设备的运行阻力，为了保证系统的正常运行，除尘器阻力的上限超出范围内，由PLC脉冲自动控制器通过定阻或定时发出指令，进行压缩空气脉冲喷吹清灰。

As the filtering condition continues, the dust accumulated on the outer surface of the filter cartridge will accumulate more and more, which will correspondingly increase the operating resistance of the equipment. In order to ensure the normal operation of the system, the upper limit of the resistance of the dust collector exceeds the range. The PLC pulse automatic controller sends instructions through fixed resistance or timing to carry out compressed air pulse jet cleaning.

产品特点:

Product features:

■ 滤筒采用聚四氟乙烯材料，表面热覆了一层纤维膜，它可以直接将粉尘阻接在滤材的表面上；

The filter cartridge is made of polytetrafluoroethylene material, with a layer of fiber membrane coated on the surface, which can directly block the dust onto the surface of the filter material;

■ 滤料折褶使用，可增大过滤面积，并使除尘器结构更为紧凑；

The use of filter material folding can increase the filtering area and make the structure of the dust collector more compact;

■ 与同体积除尘器相比，过滤面积相对较大，过滤风速较小，阻力小；

Compared with the same volume dust collector, the filtering area is relatively larger, the filtering wind speed is smaller, and the resistance is small;

■ 除尘器清灰采用脉冲喷吹在线清灰方式，清灰过程由脉冲控制仪自动控制，组合式除尘器清灰采用分离式脉冲自动循环清灰。每个除尘室内设置多个滤筒以增加其过滤面积，当某个除尘室内滤筒满足清灰设定要求时，即启动喷吹装置进行清灰，其他除尘室正常工作，即达到清灰目的，又保障除尘器正常运转；

The dust collector adopts a pulse injection online dust cleaning method, and the dust cleaning process is automatically controlled by a pulse control instrument. The combined dust collector uses a separate pulse automatic cycle for dust cleaning. Each dust removal room is equipped with multiple filter cartridges to increase its filtration area. When a certain dust removal room filter cartridge meets the requirements for dust removal, the spraying device is activated for dust removal, and other dust removal rooms work normally to achieve the purpose of dust removal while ensuring the normal operation of the dust collector;

■ 除尘效率高，且设备使用寿命长。

High dust removal efficiency and long service life of the equipment.
