Abstract

The invention discloses a filtering device, which comprises a first filter, a second filter and a third filter; a first input pipe with a first input valve is arranged at the inlet end of the first filter; There is a first output pipe with a first output valve; a second input pipe with a second input valve is provided at the inlet of the second filter, and a second output pipe with a second output valve is provided at the outlet; The inlet end of the three filters is provided with a third input pipe with a third input valve, and the outlet end is provided with a third output pipe with a third output valve; the first filter and the second filter are connected in parallel to form a parallel filter group; The free ends of the three input pipes are connected to the output ends of the parallel filter groups, or the free ends of the third output pipe are connected to the input ends of the parallel filter groups. The filtering group device can connect two filters in series, and the filtering effect is good. The present invention also provides a petroleum hydrogenation system, which uses the above filter device and can improve the purity of hydrogenation raw materials.

Description

technical field [0001] The present invention relates to the technical field of filter equipment, more specifically, to a filter device, and also to a petroleum hydrogenation system. Background technique [0002] With the development of science and technology, filtration equipment is more and more used in industrial production, such as in the petroleum processing industry, it is necessary to use a hydrogenation system to remove impurities such as sulfur and nitrogen in the petroleum, and the hydrogenation system includes For the filtration device and hydrogenation device of hydrogen raw materials, the structure of the existing filtration device will be described in detail below by taking the filtration device of the petroleum hydrogenation system as an example. [0003] The filter device of the existing petroleum hydrogenation system includes a main filter and a standby filter connected in parallel, the main filter is located on the first parallel branch road, and the input p...
