Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0019] See attached figure 1 , a rotary diversion type backwashing liquid filter, as a specific embodiment, the filter is arranged horizontally, and specifically includes a liquid inlet chamber 1, a liquid outlet chamber 2, a sewage discharge chamber 3, a filter element 4, a filter cartridge 5, Distribution plate 6, guide pipe 7, rotary bearing 8, central shaft 9, rotary controller 10, liquid inlet 11, liquid outlet 12, sewage outlet 13, filter housing 14 and supporting legs 15. The distribution plate 6 divides the filter 14 into two parts, the liquid inlet chamber 1 and the liquid outlet chamber 2 . The pre-filtered liquid liquid inlet 12 is connected with the liquid inlet chamber 1, and the guide pipe 7, the rotating bearing 8, and the central shaft 9 are all installed in the oil inlet chamber. The filtered liquid outlet 12 is co...

The invention relates to a rotary diversion type backwashing fluid filter. The filter comprises a fluid inlet cavity, a fluid outlet cavity, a pollution discharge cavity, filter elements, filter cylinders, a distribution board, a diversion tube, a rotary bearing, a central shaft, a rotary controller, a filter shell of the filter and support legs, wherein the distribution board separates the filterinto the fluid inlet cavity and the fluid outlet cavity, the filter cylinders are welded on the distribution board and are communicated with distribution holes in the distribution board, the filter elements are installed in the filter cylinders, the filter cylinders are mutually independent, the diversion tube is of a hollow bent tube structure, one side is opposite to the distribution board, andthe other side is installed on the rotary bearing and is communicated with the pollution discharge cavity. When in backwashing, the diversion tube rotates by a certain angle and stops at a certain distribution hole, so that the filter element in the filter cylinder corresponding to the diversion tube is back washed. After backwashing for a while, the diversion tube rotates to a next distributionhole to wash the next filter element till the whole backwashing is completed, then the diversion tube rotates to a standing vacant site. Due to adoption of the design of rotary diversion structure, only one filter element in the filter is back washed, and other filter elements keep filtering.
Description
technical field [0001] The invention relates to a rotary diversion type backwashing liquid filter, in particular to a filter composed of multiple sets of filter cores, in which each set of filter cores is backwashed one by one by way of rotary diversion. Background technique [0002] In the process of petroleum refining, especially under the increasing processing volume of high-sulfur oil in my country and the increasingly stringent environmental protection requirements, the hydrogenation process in many refineries is the only way to realize the light-weight processing of high-sulfur oil and heavy oil. means. However, the hydrogenation unit is easily forced to reactivate and replace the catalyst due to the rapid increase of the pressure drop of the reactor bed due to the introduction of impurities in the feedstock oil, resulting in unplanned shutdown of the unit, shortened maintenance period, and economic losses. Selecting a raw material oil backwash filter system with relia...
