Bag dust collector is a kind of dust removal equipment commonly used in industrial production, which filters out the dust in the air through the filter bag, so it plays an important role in the cleaning of the production environment and the health of employees. In order to ensure the efficiency and service life of the bag dust collector, it must be cleaned and maintained regularly. This paper will introduce the cleaning method of bag dust collector in detail.

1. Offline cleaning

Off-line dust cleaning is a common method of bag dust collector cleaning, its main steps are as follows:

(1) Stop: First of all, you need to stop the bag dust collector, and then close the air intake and outlet.

(2) Open the dust cleaning door on the dust collector: When opening the dust cleaning door, it is necessary to open the valve of the dust cleaning system, and there is no element that obstructs the airflow, in order to shorten the dust cleaning time.

(3) Cleaning the filter bag: Through the ash cleaning system jet compressed air or nitrogen, the dust at the bottom of the bag will be shaken off to avoid clogging.

(4) Close the cleaning door: close the cleaning door after cleaning, and close the valve of the cleaning system.

(5) Restart: re-open the air inlet and air outlet, and start the bag dust collector.

2. Clean the ash online

Online cleaning is an efficient and automatic method of bag dust collector cleaning, which has the following advantages compared with offline cleaning:

(1) Cleaning will not affect the normal operation of the equipment, improve the utilization rate and production efficiency of the equipment.

(2) During the cleaning process, bag pressure and air volume will not change.

(3) Extend the service life of the filter bag and reduce equipment maintenance and replacement costs.

The specific steps of online cleaning are as follows:

(1) When the filter bag is working normally, it is necessary to monitor the pressure and temperature status of the owner in real time, and clean the filter bag when it is found to be blocked.

(2) Open the cleaning system: under normal circumstances, the control system of the bag dust collector will automatically identify the filter bag that needs to be cleaned, and then the cleaning system will spray compressed air or nitrogen to the filter bag through the electromagnetic pulse valve, and the dust on it will be shaken off.

(3) Close the cleaning system: when the cleaning is finished, it is necessary to close the valve of the cleaning system.

(4) Check the normal operation of the equipment: after the end of cleaning, it is necessary to check whether the air inlet and outlet of the filter bag dust collector are opened to ensure that the equipment can work normally.

These are the two common methods for cleaning the bag dust collector. In the actual cleaning process, it is necessary to choose the appropriate cleaning method according to the use of the filter bag and the actual environment, and regularly maintain and maintain the equipment to ensure the normal operation and service life of the equipment.
