　　车间除尘设备之焊烟除尘器

Welding smoke dust collector for workshop dust removal equipment

　　焊烟除尘器是一种工业环保设备，通常用在锡焊、手弧焊等焊接场所，用来收集净化产生的焊接烟尘，起到保护环境，保护工人身体健康的目的。

Welding smoke dust collector is an industrial environmental protection equipment, usually used in welding sites such as tin welding and manual arc welding, to collect and purify welding smoke generated, playing a role in protecting the environment and protecting the health of workers.

　　焊烟除尘器主要由风机、电动机、吸气臂、吸气罩、过滤筒、粉尘收集装置、火花捕捉器及防飞溅挡板等组成。

The welding smoke dust collector mainly consists of a fan, an electric motor, an suction arm, an suction hood, a filter cylinder, a dust collection device, a spark catcher, and an anti splash baffle.

　　在烟尘净化系统运行中，有害烟尘通过吸气臂进入净化系统，净化系统内部进风口的飞溅火花分离装置可拦截缓冲在管道内随气流快速移动的飞溅和大颗粒粉尘，并直接被分离掉入下方的粉尘收集装置。细微的粉尘进入净化系统内部后也随之减慢速度，随气流飞向过滤筒，被过滤筒截留后在过滤筒表面不断堆积，在此过程中过滤筒的风阻因粉尘的不断堆积而变高。

In the operation of the smoke and dust purification system, harmful smoke and dust enter the purification system through the suction arm. The splashing spark separation device at the internal air inlet of the purification system can intercept and buffer the splashing and large particle dust that moves rapidly with the airflow in the pipeline, and it is directly separated and dropped into the dust collection device below. After fine dust enters the purification system, it also slows down and flies towards the filter cartridge with the airflow. After being intercepted by the filter cartridge, it continuously accumulates on the surface of the filter cartridge. During this process, the wind resistance of the filter cartridge increases due to the continuous accumulation of dust.

　　这时，净化系统的控制系统通过压差感应器对比一直处于监控状态，当风阻到达一定值，也就是影响到吸风量时，控制系统自动轮流打开压缩空气电磁阀，通过过滤筒内的喷嘴逐个对过滤筒进行反吹清灰。吹落的粉尘直接掉入下方的粉尘收集装置。

At this point, the control system of the purification system is constantly in a monitoring state through pressure difference sensors. When the wind resistance reaches a certain value, which affects the suction air volume, the control system automatically turns on the compressed air solenoid valve, and uses the nozzles inside the filter cylinder to blow back and clean the dust one by one. The blown dust directly falls into the dust collection device below.

　　车间除尘设备之滤筒除尘器

　　滤筒除尘器设备的过滤元件是滤筒，滤筒的构造分为顶盖、金属框架、褶形滤料的底座4部分。

The filtering element of the filter cartridge dust collector equipment is the filter cartridge, and the structure of the filter cartridge is divided into four parts: the top cover, the metal frame, and the base of the pleated filter material.

　　滤筒除尘器中的布置很重要，滤筒可以垂直布置再箱体花板上，也可以倾斜布置再花板上，用螺栓固定，并垫有橡胶垫；花板下部分为过滤室，上部分为净气室。滤筒除了用螺栓固定外吗，方便的方法是自动锁紧装置和橡胶压紧装置，这两种方法对安装和维修方便。

The layout of the filter cartridge dust collector is very important. The filter cartridge can be vertically arranged on the box flower board or tilted on the flower board, fixed with bolts and padded with rubber pads; The lower part of the flower board is a filtration chamber, and the upper part is a purification chamber. Besides being fixed with bolts, the convenient methods for filter cartridges are automatic locking devices and rubber compression devices, which are convenient for installation and maintenance.

　　滤筒除尘器设备工作原理

Working principle of filter cartridge dust collector equipment

　　含尘气体进入除尘器灰斗后，由于气流断面突然扩大，气流中一部分颗粒粗大的尘粒再重力和惯性力作用下沉降下来，粒度细、密度小的尘粒进入过滤室后，通过布朗扩散和筛滤等综合效应，使粉尘沉积再滤料表面，净化后进入净气室由排气管经风机排出。

After the dusty gas enters the dust hopper of the dust collector, due to the sudden expansion of the airflow cross-section, a portion of the coarse dust particles in the airflow settle under the action of gravity and inertia force. The fine and low density dust particles enter the filter chamber, and through the comprehensive effects of Brownian diffusion and screening, the dust settles on the surface of the filter material. After purification, it enters the clean air chamber and is discharged by the fan through the exhaust pipe.

　　车间除尘设备之铸造厂电炉除尘器

Dust removal equipment for workshop: Foundry electric furnace dust collector

　　铸造厂电炉除尘器烟气进口处增加预沉降均温设计，避免烟气对滤袋直接冲刷，利用预沉降减少大颗粒烟尘 对滤袋的负荷，减少烧滤袋现象，延长滤袋使用寿命。采用离线清灰，比在线清灰效果好，无二次吸附现象。设计过程中，优化滤袋排列，降低除尘器阻力损失。高可靠性低压大规格脉冲阀配置，反吹效果好。

Add pre settling uniform temperature design at the flue gas inlet of the electric furnace dust collector in the foundry to avoid direct flushing of the filter bag by the flue gas. Utilize pre settling to reduce the load of large particle smoke and dust on the filter bag, reduce the phenomenon of burning the filter bag, and extend the service life of the filter bag. Using offline cleaning has a better effect than online cleaning, and there is no secondary adsorption phenomenon. During the design process, optimize the arrangement of filter bags to reduce the resistance loss of the dust collector. High reliability low-pressure large specification pulse valve configuration, with good backflushing effect.
