Technical Analysis of pulse bag filter debugging and maintenance and overhaul

In recent years, the air pollution control caused the concern of all walks of life, this article will introduce the pulse bag filter debugging and maintenance, involving the pulse bag filter debugging: stand-alone debugging; simulation no-load test; linkage debugging;

1, stand-alone debugging

When the dust collector pneumatic control valve selection, the staff first connected to the compressed air, check the tightness of the gas system to check whether the pneumatic components to work properly; ash system power test run, check whether the normal work; when When using the hair dryer, power on the fan test run, turn off the hair dryer after working properly.

2, simulation of no-load test

First of all, one by one to check the solenoid valve, exhaust valve, feeder, screw conveyor line and the valve open and closed normally, then press the timing control time, according to electronic control procedures for the entire process of cleaning the room.

3, linkage debugging

Close all inspection doors and manhole door, start the system fan; mediate the load of the filter unit room, so that it reaches a basic balance. With Pitot tube and U-shaped pressure gauge to measure the dynamic pressure value of the inlet manifold, adjust the inlet manifold on the butterfly valve, is the unit of room air flow rate is basically the same. After the good red paint on the butterfly valve mark, locking handle.

4, real-time operation

Process equipment officially run, the official precipitator dust filter, PLC programmable controller also formally put into operation (usually run 5min ahead of schedule), at any time on the operating components, valves were checked and recorded good operating parameters. If according to the timing control, when the resistance of the precipitator reaches the stipulated resistance value (such as 1500 ~ 1700), manually open the PLC programmer to clean the filter bag, stop the ash after the chambers are finished, and then the statistical resistance reaches again Prescribed value of the time, and then manually open the PLC program control device into the bag cleaning, so many times. After the second cleaning cycle to obtain a smooth interval between the time that the data can be used as a programmer "timing" control of the base, enter the programmer. Then, the programmable controller can be automatically "timing control" officially run.

In the production site has been debugging a good pulse bag filter, easy maintenance and repair up

Pulse bag filter maintenance and repair:

(1) Put into operation, there should be someone management and maintenance, familiar with the working principle and technical performance of the precipitator, master the adjustment and maintenance methods, each class should tour inspection, the establishment of operating records.

(2) Compressed air oil and water separator, filter, gas tank gas bag discharge once or twice.

(3) compressed air filter material every 2 to 6 months to be replaced once.

(4) pulse controller and electromagnetic pulse valve should be hand-guided tour, each class should be less than twice, check the injection is normal, if any failure should be immediately ruled out.

(5) electromagnetic pulse valve should be cleaned once every three months and replace wearing parts.

(6) Regularly check the U-type pressure gauge changes. If more than or less than the required range to find out why. Generally through the pulse controller to adjust the injection cycle.

(7) Exhaust outlet ash if gray phenomenon, should check the filter bag is off, damaged, the frame plate is loose, the rubber mat is aging, you can open the box to determine.

(8) If the exhaust port is found ash after each injection, it belongs to the excessive cleaning, and the cleaning cycle should be adjusted.

(9) Mechanical transmission parts should be regularly injected lubricating oil, replace wearing parts.

(10) Various types of rubber seals should be replaced regularly.

(11) every six months should check the bag in good condition.

After the pulse bag filter debugging to ensure that maintenance work will be done properly, you do not have to worry about the dust removal equipment and service life.
