Working Principle Of BLU-JQZ-05 Jet Fuel Hydrogenation Unit Filter Element

  • Multiple BLU-JQZ-05 wedge wire screen filter element units form the filter system.
  • Under normal working conditions, the raw material medium enters the filter assembly through the ball valve, and the filter element intercepts the solid particles in the medium and prevents accumulation on the surface of the filter element.
  • The efficiency of the filter element is gradually reduced, and the pressure difference between the inlet and outlet of the filter system is gradually increased.
  • When the pressure difference increases to a certain set value, the program controller acts, and the filter element realizes automatic backwashing.

Advantage Of BLU-JQZ-05 Jet Fuel Hydrogenation Unit Filter Element

  • The filtering effect is good, and the economic benefit is obvious.
    The filter element can effectively remove impurity particles larger than 25 μm in the raw material, avoid the accumulation of impurities in the catalyst bed, and reduce the increased rate of the pressure drop of the reactor.
    The loss caused by the shutdown of the device due to the increase in pressure drop is avoided, the amount of catalyst in the device is reduced, and the production cost is reduced.
  • Good environmental protection effect。
    Both filtration and backflushing are carried out in a closed manner, during which no oil will leak out.
    At the same time, because the backwash uses raw oil instead of steam, it avoids the pollution caused by steam blowing light dirty oil into the air.
  • The high degree of automation.
    In the automatic mode of the backwash filter element, the actions of all its valve groups are controlled by the PLC program control equipment, without manual operation, which reduces the labor intensity of the operator.
    Moreover, the process of connecting filtration and backwashing has little fluctuation, which ensures the continuity and stability of the process medium.
  • It can provide automatic and manual operation modes to meet the requirements of different working conditions.

The application of the BLU-JQZ-05 automatic backwashing filter element in the 200,000 hydrogenation unit significantly reduces the rate of pressure drop rise, protects the catalyst, prolongs the operation cycle, and brings considerable economic benefits.
