Product Desciption
Device structure and working principle
The filter consists of two filter cartridges, each cartridge filter built multiple roots, filter imported filter material. The backwash of the filter housing has two vertical barrel and multiple master valves. Compact structure, small footprint, easy piping layout.
When the filter filter surface during use of aggregates increased inlet manifold pressure difference between the discharge increases, the pressure reaches a set value, the filter through the PLC automatic control switch, maintaining the production of continuous operation, while being switched by the backwash filter media backwash backwash process is complete, pressure recovered to the original state, the filter and into the normal standby state. The use of filters used in a way to open a backup job.
When the process flow or require continuous flow system operating pressure is low, the flow of solid particles with higher levels of the body, containing waxes, asphaltenes, dirty things (such as slag material) and other process fluids, the use of gas-assisted backwash is most preferred filtration method. Refinery in a fluidized catalytic cracking unit to remove the catalyst powder and oil varnish to enhance the value of the backwash filter technology can be very effective in extending the service life of the catalyst, improving hydrotreating and hydrocracking conversion rate. In the gas-assisted backwash, the rapid relief of the expansion of compressed air bubbles within the liquid viscous material after blasting back through (from the inside) filter element, which speeds up the forward velocity seven times normal,
This has effectively the accumulated debris on the filter element in addition to punch, while substantially reducing the generated amount of backwash liquid (i. E., oil or sewage). Thus, the discharge liquid in a high concentration of solid content. Gas-assisted backwash technology and high sink capacity filtration technology, making the backwash cycle with a long filter time interval.
Gas-assisted automatic backwash filter from the filter container, air source air tank, switching valve and procedural controllers and other products make up the system. Its main feature is the automatic backwash, and in any backwash period, only one container is in backwash, while the other has been in the container-line operation, you can continuously filter material media. Under normal operating conditions, raw material medium through high performance sealing valve into the filter, the filter element will be the medium of solid particles intercepted barrier and produce the appearance of the filter element accumulation, import and export filter system pressure gradually increases, when the pressure difference increases to a set value, the work program controller and the actuator moves, in turn open the reserve container (B container) import, export valve, and then click Close filter container (A container) import and export of valves, open simultaneously compressed gas inlet valve and delay to the A sufficient compressed gas containers, after quickly open the drain valve, filter elements within the container looks thoroughly rinse off after discharge waste oil off the inlet valve drain valve. A container backwashing into the pending operation.
When A container backwashing, B container work when the pressure increases to the set value, B the same container according to the above work is pending order backwashing operation. To avoid switching drying, after each flush full replacement filter media material.
Normal operating conditions, the medium from the bottom through the filter assembly from the upper outlet manifolds output.
Recoil working condition, washing the filter element cleaning media from top to bottom, the outer surface of the filter element and into the dirt accumulation flush
