Hydrogenation Backwash Filter Element
The hydrogenation raw materials need to be filtered. If the mechanical impurities are not removed, they will be deposited on the top of the reactor, so that the pressure difference of the reactor is too large and forced to shut down, thus shortening the operation cycle of the unit.
Johnson wedge wire screen automatic backwash filter can solve this problem perfectly.
Johnson screen filter is set in the automatic backwash filter, which can filter solid impurity particles ≥ 25um.
When the pressure difference between the inlet and outlet of the filter is greater than the set value (0.1 ~ 0.18mpa), start the backwashing mechanism to carry out backwashing, and wash off the impurities on the wedge wire screen filter element.
Recently, the pressure difference of feed filter in the hydrocracking unit increased rapidly and the switching period of the filter was shortened. In order to meet the needs of production, the secondary line of the filter had to be opened for control. The long-term operation of the unit under the condition of opening the filter by-line will affect the long-term operation of the unit. Therefore, the hydrogenation workshop analyzes the causes of the blockage of the raw material filter and makes treatment measures.
The wedge wire screen filter element of the backwash filter in the hydrogenation unit has high filtering precision and overall strength and can be automatically cleaned and regenerated online. It is safe and reliable, meets the requirements of environmental protection, and has no secondary pollution. It can reduce the equipment downtime of downstream process production and ensure the safety of the system and equipment.
For the continuous automatic production of petroleum, petrochemical, chemical, metallurgy, electric power, and other industries, through the process control of filtration, separation, purification and fluidization, the quality grade, production efficiency, resource, and energy utilization rate of downstream products are improved.
