（1）运行阻力大

(1) High operating resistance

原因可能是：①结露糊带；②脉冲阀不工作或损坏；③压缩空气压力太低；④脉冲阀工作时提升阀未关闭或关闭不严；⑤一个或多个提升阀处于关闭状态。

The reason may be: ① condensation and paste; ② Pulse valve not working or damaged; ③ The compressed air pressure is too low; ④ When the pulse valve is working, the lifting valve is not closed or not tightly closed; ⑤ One or more lift valves are in the closed state.

排除方法：①堵塞漏洞，提高烟气温度，加强通风，做好除尘器及管路的温度工作；②维护或更换脉冲阀；③检查气路系统及空气压缩机；④检查提升阀和清灰控制器。

Troubleshooting method: ① Block the loophole, increase the temperature of the flue gas, strengthen ventilation, and do a good job in the temperature of the dust collector and pipeline; ② Maintain or replace the pulse valve; ③ Check the air circuit system and air compressor; ④ Check the lifting valve and ash cleaning controller.

（2)运行阻力小

(2) Low operating resistance

原因可能是：①烟气短路；②滤袋破损；③测压装置或主引风机电流表失灵。

The reason may be: ① smoke short circuit; ② Damaged filter bag; ③ The pressure measuring device or the main induced draft fan ammeter is malfunctioning.

排除方法：①此时可见浓度排放增加，检查并补焊；②检查并更换滤袋；③更换或修理风机电流表。

Exclusion method: ① At this point, the visible concentration emission increases, check and repair welding; ② Check and replace the filter bag; ③ Replace or repair the fan ammeter.

（3）脉冲阀不工作

(3) Pulse valve not working

原因可能是：①电源断电或清灰控制器失灵；②气缸或卡死；③气缸电磁换向阀线圈烧坏；④气缸电磁换向阀太脏，换气口堵塞或阀芯干涸，运动不了；⑤压缩空气压力太低；

The reason may be: ① Power outage or malfunction of the ash cleaning controller; ② Cylinder or stuck; ③ The coil of the cylinder electromagnetic directional valve is burnt out; ④ The cylinder electromagnetic directional valve is too dirty, the air exchange port is blocked, or the valve core is dry, making it unable to move; ⑤ Compressed air pressure is too low;

排除方法：①恢复供电或修理清灰控制器；②仔细检查、清理、修理气缸；③更换电磁阀换向阀及线圈；④检查气路系统及压缩机。

Troubleshooting method: ① Restore power or repair the dust cleaning controller; ② Carefully inspect, clean, and repair the cylinder; ③ Replace the solenoid valve reversing valve and coil; ④ Check the air circuit system and compressor.

（4）滤袋的维修和更换

(4) Repair and replacement of filter bags

一般情况下，滤袋便用年限内是逐渐损坏的，主要原因是粉尘的腐蚀、高温、高湿引起的滤料变质。除尘器不能使用破损的滤袋进行工作，否则会影响除尘效果。

In general, the filter bag gradually damages within its service life, mainly due to the corrosion of dust, high temperature, and high humidity causing deterioration of the filter material. Dust collectors should not use damaged filter bags for operation, otherwise it will affect the dust removal effect.
