Pulse jet filter cleaning can be used online or off-line cleaning methods. Manual cleaning means during pulse jet, dust bag still flue gas filtration. Injection systems require the use of a relatively high use of filter blocking airflow blowing smoke while using instant pulse oscillation enable dust layer peeling off into the hopper. Manual cleaning dust inside is a large space static chamber, air is more evenly distributed, so that the filter media is exposed to load changes is not too large, so extended bag life. Another cleaning system requires the internal filter area is divided into several chambers sealed bags, each bag house flower stand-alone installation board outlet shut-off valve, solenoid valve cylinder and compressed air control system. Before each pulse jet cleaning bag house, we need to make the shutter control bag house filter no longer smoke. Thus, the off-line cleaning mechanism is more complex, and with Shutdown valves, so the cost of maintenance and cleaning off dust is relatively fine gray dust higher than online. In fact, it should be based on the nature of the flue gas and process requirements, flexible choice of online or offline cleaning system design. In some special processes such as waste incineration, with its loose dust properties, not easy to form a cake, effective cleaning is also more difficult. Another cleaning method can reduce the “secondary dust” to make a more thorough cleaning stage, to reduce the resistance of the device results.
