Description

Technical Field

[0001] The utility model relates to the technical field of raw oil filters, and more specifically to an improved raw oil filter for a hydrocracking device. Background Art

[0002] Crude oil filters are mainly used to filter out larger particles of sand, fine stones and other impurities in crude oil, which plays a very important role in effectively protecting the normal operation of the pump. Hydrocracking crude oil filters use atomic combinations such as the fission of hydrogen atoms to carry out catalytic cracking under hydrogen conditions, which can inhibit the dehydrogenation condensation reaction during catalytic cracking and avoid the formation of coke. High-grade products without olefins can be obtained, and the liquid yield can be as high as 100% or more. Hydrocracking is essentially an organic combination of hydrogenation and catalytic cracking processes, which can convert heavy oil products into light oil products such as gasoline, kerosene and diesel through catalytic cracking reactions.

[0003] Traditional crude oil filters use a multi-layer filter stacking method. Although the increase in the number of layers can improve the filtering effect to a certain extent, it will reduce the filtering efficiency. In addition, the multi-layer filter is limited by the filter structure, and the area of ​​a single filter is easily limited and reduced, which indirectly increases the risk of filter clogging.

The crude oil inlet 3 and the outlet 4 form a ninety-degree angle. An assembled filter element is arranged on the path from the crude oil inlet 3 to the outlet 4. The assembled filter element is divided into a first filter element 5 and a second filter element 6. A connecting port 51 is arranged at a side end of the first filter element 5, and the second filter element 6 is inserted and installed on the connecting port 51. The first filter element 5 includes a primary filter screen 52, a filter wall 53, a mounting block 54, and a magnetic rod 55. The primary filter screen 52 is nested and installed in the crude oil inlet 3, and a filter wall 53 is connected to the primary filter screen 52. The filter wall 53 is spaced 2-5 cm from the inner wall of the housing 1. A mounting block 54 is clamped inside the filter wall 53, and a fixed magnetic bar 55 is connected to the mounting block 54. The second filter element 6 includes a mounting shell 61 and an inner filter screen 62. The inner filter screen 62 is fitted and installed on the inner wall of the mounting shell 61, and a connecting port 64 is provided through the mounting shell 61. A circulation channel 63 is provided inside the inner filter screen 62. The raw oil filtered by the first filter element 5 enters the second filter element 6 from the circulation port for filtration, and after being filtered by the inner filter screen 62, it is transferred to the circulation channel 63 for output. The filter wall 53 in the first filter element 5 is arranged in a large area in the vertical direction, and can be arranged in a ring shape, which reduces the risk of clogging of the filter screen.
