Matters needing attention before and during the use of bag filter


After installing the bag filter, test the equipment after idling test run. During the test run, be careful and find out what problems are, and adjust and change. The matters needing attention before and during the use of bag filter are as follows:

When commissioning new bag filter equipment, the following should be noted:


1. Fan rotation direction (forward and reverse points), speed, bearing vibration and temperature.


2. If the designed pressure and temperature test points are the fan and air volume.


3. If there is moisture in the dust bag room, is the ash system unblocked to prevent blockage and corrosion, which will affect the serious pollution of the production host?


4. The installation of bag dust removal, and whether the leakage means. After using the bag to take out whether there is any, let go and wear, you can put into operation vision to determine the chimney emissions.


5. Check the equipment and accessories for any abnormalities when they are idle, and promptly treat them. No matter the connection between the devices is smooth.


袋式除尘器使用前和使用中应注意事项 Before running the bag filter with problems , please pay attention to the following matters :


1. Boot, should be connected to a compressed air storage tank, connected to a control power source, start the cinder installation if there are other equipment in the system, and if the downstream equipment is started before.


2 Soot or dust temperature control: The temperature of the medium is relatively high. Sometimes, in order to protect the dust bag of the cloth bag and extend its service life, the temperature of the flue gas in the dust bag entering the dust collection room must not exceed the maximum. Withstand the temperature, the air inlet flue gas channel and the front of each filter are provided with a temperature measurement point, a valve between the cold point temperature is set, and the heat-resistant temperature is controlled. To open and display the controller by the cold temperature, its control principle is to close the valve: the cold air valve opens when external air enters the pipe, so as to achieve the purpose of reducing the temperature of the soot.


3. Regularly measure the process parameters, smoke gas, temperature, concentration, etc. If an abnormality is found, the cause should be found and dealt with in a timely manner.


4. Solenoid pulse valve should be removed, such as internal impurities and moisture, should be cleaned, for example, should be replaced when the diaphragm is damaged.


5. The triple gas source of the sewage separator should be a type, while the oil-water separator 3 is cleaned once, the oil layer should be checked frequently, and the equipment should be refueled in time to avoid each injury.


6. There are two types of dust control: constant pressure control and timing control. The constant pressure mode of operation is an intake duct using a pressure filter and controlling the signal of the duct difference ΔP emitted by the differential pressure transmitter dust control. This control is based on the filter bag being discontinuous and having a clean low knot. The actual degree of scale energy consumption, less pulse operation, etc. Regular cleaning is performed at a predetermined time. It should be determined that the regular cleaning cycle is accurate, otherwise it should be adjusted. Using a constant pulse controller resistance, the work should be checked, the pressure periodically hits the pressure switch, blocked and cleaned.


7. In the constant pressure mode of operation under normal conditions, the differential pressure transmitter has a fault, the operation mode and the constant pressure mode which is automatically transmitted to the timing signal and then returned to resolve the operation.


8. When the moving parts, ash and oiling device of the deceleration machine are required to change the oil, the unevenness should be removed immediately.


9. In the normal operation of the dust removal accessories, the ash discharge device has not stopped, otherwise, the ash bucket will be quickly packed into the bag to make the overflow chamber and force the dust removal accessories to stop.


10. When shutting down, the system will keep the dust removal accessories and exhaust fan for a period of time during the shutdown process. After the dust removal equipment of moisture and dust works, it must be noted that when the dust removal accessories stop working, the dust must be cleaned repeatedly. Attachment (can be cleaned manually), dust is removed in the dust filter bag to prevent moisture and gas from the bag paste. It is not necessary to disconnect and close the compressed air source, especially when the fan is operating, the compressed air must be provided to the poppet valve cylinder to ensure that the poppet valve is open.
