BYD candle filter
Thread Content
How is backwashing and cleaning of the filter elements in the BYD reaction tank achieved? Do the inlets and outlets for various materials need to be closed during backflush cleaning? Thank you
First, check whether you are discharging continuously without stopping. If so, then the process must be reversed: feed becomes discharge, and discharge becomes feed for backblowing. If continuous discharge is not required, air can be introduced at the outlet; the pressure can be released either through the pressure relief line or through the outlet line, as long as it does not affect the subsequent processing stages.
The air pressure used for backwashing and cleaning the filter element is lower than the liquid pressure, and the air duct runs inside the filter element; its upper end is connected to the interior of the filter element. So it’s a bit confusing, right? Thank you
Is the reaction tank in continuous operation without stopping? The pressure for backflush cleaning is lower than that of the hydraulic system; there must be a problem with the design itself. Unless the reactor is depressurized first before back-blowing. The air is blown from the inside out through the trachea; outside the filter element are particles such as catalysts that serve for adsorption, while fluid flows inside it. After purging from within the filter element, the particles adsorbed on the surface of the catalyst fall off, which is equivalent to the regeneration process of the filter element. But some of the finer particles are not easy to remove; generally, they need to be replaced entirely once a year, or sent out for cleaning.
Turn off gas transmission; adjust the production tee valve to reverse blow mode
The candle-type filters in BYD reactors can operate independently, so backwashing the filters does not require shutting down the equipment.
