The DMK – 4CS – 14 controller has a built – in specific control program. Through the buttons and display window on the panel, the operator can set parameters related to cleaning, such as the pulse interval time (the time interval between two jets) and the pulse width (the duration of each jet). After setting the parameters, the controller will send out electrical signals regularly according to the set logic.
Solenoid Valve Driving
When the controller sends out an electrical signal, the signal will be transmitted to the connected pulse solenoid valve. The pulse solenoid valve is a key executive component in the cleaning system. Before receiving the electrical signal from the controller, it is in a closed state, cutting off the path of compressed air. When receiving the electrical signal, the solenoid valve opens quickly, allowing compressed air to pass through.
Compressed Air Jet
Compressed air is usually provided by an air source device (such as an air compressor) and is stored and stabilized by an air storage tank to ensure that there is compressed air with sufficient pressure and flow. When the pulse solenoid valve is opened, the compressed air will pass through the orifice on the injection pipe at a very high speed, forming a powerful pulse air flow.
Filter Bag Cleaning
These high – speed pulse air flows are directly injected into the interior of the filter bag. Under the action of the pulse air flow, the filter bag will expand instantaneously, generating an outward tension. Since there are dust and other impurities attached to the surface of the filter bag, under the expansion of the filter bag and the impact of the air flow, the dust attached to the surface of the filter bag will be shaken off and fall into the ash hopper below, thus realizing the cleaning of the filter bag, restoring the filtering performance of the filter bag, and ensuring the continuous and efficient operation of the dust removal equipment.
