Description

Technical Field

[0001] The utility model relates to the field of oil refining equipment, and more particularly to oil refining equipment with crude oil impurity filtering function. Background Art

[0002] When existing oil refining equipment is in use, the filtering effect of crude oil is achieved through the filtering components therein. After long-term operation, the filter plates and filter layers used to filter crude oil will cause the filtering effect to decline due to the adhesion of crude oil impurities or wear after long-term use. In this case, the filter plates and filter layers need to be replaced. The replacement of the filter plates and filter layers needs to be done during shutdown. In order to ensure work efficiency, some equipment is usually equipped with two sets of transmission pipelines with supporting valves. When the filter components in one pipeline need to be cleaned and replaced, the other pipeline can be opened for use through valve control. However, no matter which oil refining equipment has crude oil filtration, it has the following problems:

[0003] During the assembly and use of the filter plate and pipeline, the crude oil input pipeline is filtered through the filter plate. The impurities filtered out in the process will be concentrated at the oil inlet end of the input pipeline. In addition, most of the existing filter plates are set vertically, which will cause the crude oil impurities to either be concentrated in large quantities at the oil inlet end of the input pipeline, or be concentrated on the surface of the filter plate due to the influence of subsequent crude oil input. As a result, the subsequent cleaning of both the pipeline and the filter plate is time-consuming and labor-intensive.

[0004] Therefore, the utility model proposes an oil refining equipment with crude oil impurity filtering function. Utility Model Content

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-3 drawings in the embodiments of the present utility model.

[0020] Please refer to Figures 1-3 , in the embodiment of the present utility model, a refinery equipment with crude oil impurity filtration includes a device main body 1. One side of the top end of the device main body 1 is fixedly connected with an adding pipe 2. One side of the bottom end of the device main body 1 is fixedly connected with a collection box 3. The bottom end of the device main body 1 is fixedly connected with a supporting docking pipe 4, an input pipe 5, a connecting flange 7 and an outlet pipe 6. The bottom end of the outlet pipe 6 is communicated with a branch pipe 8. The outer side of the branch pipe 8 is communicated with a recovery pipe 10. The bottom end of the device main body 1 is also fixedly connected with a mounting base plate 11.

[0021] In the embodiment of the present utility model, the upper part of the device main body 1 is trapezoid-shaped and set as a crude oil storage part, and the lower part is trapezoid-shaped and open, set as a pipe installation area. The mounting base plate 11 is fixedly connected to the lower surface of the device main body 1. The whole docking pipe 4 is located at the lower part of the device main body 1 and is communicated with the device main body 1. The input pipe 5 is communicated with the docking pipe 4. The input pipe 5 and the outlet pipe 6 are horizontally communicated and docked through the connecting flange 7. The four components of the docking pipe 4, the input pipe 5, the connecting flange 7 and the outlet pipe 6 are all fixedly installed on the surface of the mounting base plate 11. By means of the docking pipe 4 cooperating with the input pipe 5 and the outlet pipe 6, the effect of exporting and conveying the crude oil from the device main body 1 is achieved. At the same time, the input pipe 5 and the outlet pipe 6 are connected through the connecting flange 7, which is convenient for subsequent disassembly, cleaning and replacement operations.

[0022] The whole branch pipe 8 is arranged downward and obliquely outward (towards the outlet end of the outlet pipe 6), and is connected with the outlet pipe 6 as a whole in a "Y" shape. The filter plate 9 is integrally inclined and embedded in the branch pipe 8 and the outlet pipe 6. The bottom end of the filter plate 9 is close to the inner end corner position of the branch pipe 8 (the end close to the recovery pipe 10), and the top end of the filter plate 9 abuts against the top inner wall of the outlet pipe 6. By means of the branch pipe 8, the effect of facilitating the inclined installation of the filter plate 9 inside the outlet pipe 6 is achieved. By means of the filter plate 9, the effect of filtering the crude oil exported from the outlet pipe 6 is achieved. At the same time, due to the inclined installation of the filter plate 9, cooperating with the branch pipe 8, the effect of facilitating the collection of the impurities filtered from the crude oil is achieved, which is convenient for subsequent separate cleaning operations of the impurities.

[0023] The recovery pipe 10 is arranged in an "L" shape. The top end is connected with the branch pipe 8 and the bottom end is connected with the collection box 3. At the same time, the interface between the recovery pipe 10 and the branch pipe 8 is located on one side of the filter plate 9. By means of the recovery pipe 10, the effect of exporting the crude oil impurities filtered and collected in the branch pipe 8 is achieved.

[0024] When this device is in use, crude oil is input from the equipment main body 1 into the docking pipeline 4, and then enters the input pipeline 5 and flows along the direction of the export pipeline 6 for transportation. When passing through the position of the branch pipe 8, the filter plate 9 at this place filters the crude oil. The filtered crude oil continues to be input through the export pipeline 6. Since the branch pipe 8 is arranged obliquely outward, and the filter plate 9 is also arranged obliquely in the branch pipe 8, there is a relatively large space at the connection position between the branch pipe 8 and the export pipeline 6. As a result, impurities generated by filtration and the like can be concentrated at the connection between the export pipeline 6 and the branch pipe 8. With the concentration of impurities, they are recovered through the recovery pipeline 10 connected to the branch pipe 8 and collected in the collection box 3.

[0025] The docking pipeline 4, the input pipeline 5, the connecting flange 7 and the export pipeline 6 are configured as a pipeline system of this application. According to the prior art, two sets of this pipeline system can be set up for alternative use. And the valve control mechanism for this pipeline system is also the prior art, so it will not be elaborated here.

[0026] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
