脉冲除尘器的结构主要分为动力（风机）单元，脉冲反吹单元，滤筒过滤单元，粉尘收集单元和电控单元，对于防爆除尘器需要增加泄爆和隔爆装置。下面虹森机电带你了解中央集尘系统负压除尘器的结构特点。

The structure of pulse dust collectors is mainly divided into power (fan) unit, pulse backwash unit, filter cartridge filtration unit, dust collection unit, and electrical control unit. For explosion-proof dust collectors, explosion-proof and explosion-proof devices need to be added. Below, Hongsen Electromechanical will take you to understand the structural characteristics of the negative pressure dust collector in the central dust collection system.

风机单元：采用电机和风叶直连式设计，噪音低，传动效率高。风叶采用铝合金材质，并经过动平衡测试，电机采用西门子电机，防护等级IP55，满足现场24小时使用的要求。

Fan unit: adopts a direct connection design of motor and fan blades, with low noise and high transmission efficiency. The fan blades are made of aluminum alloy material and have undergone dynamic balance testing. The motor is a Siemens motor with a protection level of IP55, which meets the requirement of 24-hour use on site.

脉冲反吹单元：采用螺旋式喷吹设计，连接气源即可使用，可以对滤芯进行360度喷吹，清灰无死角，保证滤芯可以处于较高的过滤风速，延长滤芯使用寿命。脉冲阀双膜片喷吹，喷吹寿命达到100万次以上。

Pulse Blowback Unit: Adopting a spiral spray design, it can be used by connecting the air source. It can spray the filter element 360 degrees to clean the dust without dead corners, ensuring that the filter element can be at a high filtering wind speed and extending its service life. Pulse valve dual diaphragm spraying, with a spraying life of over 1 million times.

滤筒过滤单元：标配日本东丽聚酯纤维滤材，PTFE覆膜处理后对0.3微米以上粉尘的过滤效率达到99%以上，滤芯表面光滑，透气性好，过滤面积大。滤芯立式安装，避免滤芯表面粉尘堆积。

Filter cartridge filtration unit: equipped with Japanese Dongli polyester fiber filter material as standard, the PTFE film coating treatment can achieve a filtration efficiency of over 99% for dust above 0.3 microns. The filter element has a smooth surface, good breathability, and a large filtration area. The filter element is installed vertically to avoid dust accumulation on the surface of the filter element.

粉尘收集单元：采用抽屉式粉尘收集结构，只需打开门板即可快速对粉尘进行倾倒，可设计不停机卸料和料位报警功能。

Dust collection unit: adopts a drawer type dust collection structure, which can quickly dump dust by opening the door panel. It can be designed with non-stop unloading and material level alarm functions.

电控单元：主要电器件采用施耐德品牌，具有缺相，过载，过热，相序保护等功能，电控面板操作简单。

Electronic control unit: The main electrical components are made of Schneider brand, with functions such as phase loss, overload, overheating, and phase sequence protection. The operation of the electronic control panel is simple.

防爆设计：除尘器安装泄压膜片，当除尘器内部压力达到设定值后，可以自动开启，快速对除尘器内部进行泄压，避免发生更大的破坏。按照相关规范要求，中央集尘系统防爆措施必须采用两种或以上的方式。

Explosion proof design: The dust collector is equipped with a pressure relief film. When the internal pressure of the dust collector reaches the set value, it can automatically open to quickly relieve pressure inside the dust collector, avoiding greater damage. According to relevant regulations, the explosion-proof measures for the central dust collection system must adopt two or more methods.
