Description

Technical Field

[0001] The present application relates to the technical field of petroleum pipelines, and in particular to a filtering device for petroleum pipelines. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid or solid hydrocarbons in a natural state. When it is transported by pipeline, it contains some residues inside. In order to facilitate the subsequent processing of the petroleum, it needs to be filtered.

[0003] In the field of oil pipeline filter devices, traditional filtering methods mainly rely on the physical interception effect of filter media, such as filter screens, filter cloths, etc. These methods are prone to cause clogging of filter media and reduce filtration efficiency when processing oil with high oil content. In addition, there are certain problems with the replacement and cleaning of filter media, such as high replacement frequency and difficulty in cleaning. In order to improve the filtering effect of oil pipeline filter devices, reduce clogging of filter media, extend the service life of filter media, and reduce maintenance costs, the existing technology has proposed a variety of improvement methods. For example, some technologies improve filtration efficiency by increasing the pore size of the filter medium or using high-strength filter media; other technologies improve filtration effect and reduce energy consumption by optimizing the structural design of the filter device, such as using multi-stage filtration and automatic backwashing.

[0004] However, the above technology still has certain limitations when processing oil with high oil content. In particular, when a large amount of oil condensation is deposited on the filter medium and the inner wall of the filter device, these oil blocks are difficult to remove by traditional cleaning methods, resulting in a decrease in filtration efficiency.

[0005] Therefore, the prior art needs to be further improved and enhanced. Utility Model Content

[0006] The present application provides a filtering device for petroleum pipelines to solve the problems in the prior art that, after long-term filtering by the filtering device, petroleum lumps are easily condensed on the inner wall of the pipeline and the surface of the filter layer, resulting in poor filtering effect and affecting normal use.

[0012] As a preferred embodiment of the present application, the multi-stage filter unit includes an inlet filter screen, an outlet detection element, and a multi-stage filter layer disposed therebetween.

[0013] As a preferred embodiment of the present application, the multi-stage filtration layer includes a coarse filter element, a medium filter element and a fine filter element arranged in sequence along the direction from the inlet filter screen to the outlet detection element. The coarse filter element is provided with a mesh whose mesh size is smaller than the mesh size of the inlet filter screen.

[0014] As a preferred embodiment of the present application, the multi-stage filter layer is detachably connected to the pipeline, and an opening and closing door is provided on the top of the pipeline, and the size of the opening and closing door is the same as that of the multi-stage filter layer.

[0016] As a preferred embodiment of the present application, a temperature control layer is provided on the outer wall of the pipeline, and an electric heating plate and a refrigerant pipe are provided inside the temperature control layer, and the two are arranged alternately.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application are:

[0029] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0032] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0034] like Figure 1 As shown, the present application provides a filtering device for an oil pipeline 40, which is arranged at the connection of the oil pipeline 40. The filtering device includes a filtering shell 10, a cleaning component 20 and a filtering component arranged on the outer wall of the filtering shell 10. The cleaning component 20 includes a flushing box 21 and a drug washing box 22, both of which are connected to the inner wall of the filtering shell 10. The filtering component includes a multi-stage filtering part 30 arranged inside the filtering shell 10 and an ultrasonic vibration part 11 arranged on the outer wall of the filtering shell 10.

[0035] Among them, Figure 1 As shown, the overall structure of the filter housing 10 may be a cylindrical structure, which may be connected to the oil inlet of the oil pipeline to perform preliminary filtering on the oil transported therein.

[0036] The chemical washing box 22 and the flushing box 21 can be arranged on one side of the filter housing 10 and connected by pipes. The structure of the box can be a barrel or box structure with an opening and closing cover to facilitate cleaning the interior of the flushing box 21 and the chemical washing box 22.

[0037] Furthermore, the ultrasonic vibration part 11 includes an ultrasonic generator, a transducer 111 and a wrapping shell 112. The outer wall covers of the ultrasonic generator and the transducer 111 are arranged on the wrapping shell 112. An opening is opened on one side of the wrapping shell 112. The transducer 111 partially protrudes from the opening and is connected to the side wall of the pipeline.

[0038] It is understandable that, with regard to the specific structure and principle of the ultrasonic generator and transducer 111, since these devices are relatively mature in the prior art, the connection and setting models between the two can be selected and assembled according to the devices on the market and in the prior art.

[0039] In addition, the ultrasonic vibration part 11 also includes a coupling layer 113, which is arranged at the part of the transducer 111 protruding from the opening of the wrapping shell 112, and the coupling layer 113 is attached to the outer wall of the pipeline. The ultrasonic generator and the outer wall cover of the transducer 111 are arranged on the wrapping shell 112, and an opening is opened on one side of the wrapping shell 112, and the transducer 111 partially protrudes from the opening and is connected to the side wall of the pipeline. The ultrasonic generator generates ultrasonic waves, and the transducer 111 transmits the ultrasonic waves to the side wall of the pipeline. Through the vibration of the ultrasonic waves, the dirt on the filter assembly can be effectively removed, and the filtering efficiency can be improved; and by setting the coupling layer 113, the ultrasonic vibration part 11 can be better attached to the outer wall of the pipeline, and the transmission efficiency of the ultrasonic waves can be improved. The coupling layer 113 is arranged at the part of the transducer 111 protruding from the opening of the wrapping shell 112, and the coupling layer 113 is attached to the outer wall of the pipeline, which can make the ultrasonic vibration part 11 better attached to the outer wall of the pipeline, reduce energy loss, and improve the transmission efficiency of the ultrasonic waves.

[0040] It should be noted that the transducer 111 referred to here is connected to the side wall of the pipeline. In order to ensure the tightness of the connection, the contact surface of the transducer 111 and the coupling layer 113 should be set to a curved structure to ensure a close fit with the pipeline, and for the coupling layer 113, it can use ultrasonic coupling glue, which is a special colloid substance used to fill the tiny gap between the transducer 111 and the pipeline to ensure the effective transmission of ultrasonic energy. Coupling glue usually has high elasticity, high conductivity and good temperature resistance. Alternatively, polyurethane can be used. The polyurethane material has good mechanical strength and wear resistance, and provides good ultrasonic transmission efficiency. They are generally used in applications requiring higher mechanical properties. Of course, in addition to these, other materials with good ultrasonic transmission effects can also be used as coupling layer 113 to ensure the transmission of ultrasonic waves.

[0041] In a preferred embodiment, Figure 1 As shown, the medicine washing box 22 includes a flushing medicine box 221 and an ultrasonic medicine box 222, both of which are independently arranged and communicated with the pipeline.

[0042] It is understandable that the flushing medicine box 221 referred to here mainly refers to the medicine or clean water used to flush the multi-stage filter part 30 and the inside of the filter housing 10. The medicine washing water here can be a petroleum solvent or a special petroleum cleaning agent. There are special cleaning agents for the petroleum industry on the market. These cleaning agents are specially formulated to effectively clean the sediments and residues in the petroleum system, and at the same time, they are less corrosive to metal and non-metal parts. As for the ultrasonic medicine box 222, it is mainly used to put in ultrasonic liquid medicine to facilitate the transmission vibration of ultrasonic waves, so as to vibrate and drop the petroleum residue condensed on the inner wall and the multi-stage filter part 30, thereby improving the cleaning effect and facilitating subsequent filtration.

[0043] During specific use, the flushing medicine box 221 and the ultrasonic medicine box 222 in the medicine washing box 22 can be cleaned alternately, and finally flushed with clean water through the flushing box 21, so as to improve the cleaning effect and ensure the cleaning ability.

[0044] Of course, in order to facilitate the discharge of water produced by cleaning, a drain outlet should be set. This drain outlet can be in a blocked state under normal use and only opened when cleaning is needed to reduce leakage during oil transportation.

[0045] As a preferred embodiment of the present application, the multi-stage filter unit 30 includes an inlet filter screen 31, an outlet detection element 32, and a multi-stage filter layer disposed therebetween. Furthermore, the multi-stage filter layer includes a coarse filter element 33, a medium filter element 34, and a fine filter element 35 disposed in sequence from the inlet filter screen 31 to the outlet detection element 32, and the coarse filter element 33 is provided with a mesh whose mesh size is smaller than the mesh size of the inlet filter screen 31.

[0046] It is understandable that by setting the inlet filter 31, large impurities are initially filtered when the oil enters the filtering device, and a detection element is set at the outlet to monitor the filtering effect in real time to ensure the quality of the oil. The multi-stage filter layer set in the middle can achieve layered filtering of impurities of different sizes in the oil and improve the filtering effect. The multi-stage filter layer includes a coarse filter 33, a medium filter 34 and a fine filter 35 arranged in sequence from the inlet filter 31 to the outlet detection element 32. The coarse filter 33 is provided with a mesh whose mesh size is smaller than the mesh size of the inlet filter 31, which can effectively filter out larger impurities and ensure the effect of the subsequent filter layer.

[0047] Among them, for the coarse filter element 33, the medium filter element 34 and the fine filter element 35, stainless steel mesh, polypropylene mesh and the like can be roughly used to form a mesh structure with a larger pore size to capture larger particles, such as sand, soil, etc.; the medium filter element 34 can use synthetic fiber filter cloth, wire mesh and the like for fiber weaving or wire weaving filter cloth to capture medium-sized particles, such as tiny metal chips, fibers, etc., for further filtration; for the static filter element, a porous structure made of ceramic filter element, polymer filter membrane and the like can be used to capture the smallest particles, such as bacteria, viruses and other microorganisms, for more detailed filtration to ensure the filtering effect of petroleum.

[0048] As a preferred embodiment of the present application, the multi-stage filter layer is detachably connected to the pipe, and an opening and closing door is provided on the top of the pipe. The size of the opening and closing door is the same as that of the multi-stage filter layer, so as to facilitate the removal of the entire multi-stage filter layer for further cleaning or replacement.

[0049] Optionally, a mounting seat 12 is provided on the inner wall of the pipeline, and a positioning frame 36 is provided on the outer wall of the multi-stage filter layer. The positioning frame 36 is detachably connected to the mounting seat 12 to simplify the disassembly and assembly structure and facilitate replacement.

[0050] In a preferred embodiment, a temperature control layer is provided on the outer wall of the pipeline, and an electric heating plate and a refrigerant pipe are provided inside the temperature control layer, and the two are arranged alternately. It can be understood that since a suitable temperature is required in oil transportation, the temperature control layer can be set to enable the pipeline to be heated or cooled to adapt to different temperature requirements and different ambient temperatures; and, when filtering and cleaning, the appropriate heating temperature can make the adhered block-shaped petroleum condensate better cleaned, further improve the cleaning effect, and facilitate subsequent filtration work.

[0051] Regarding the temperature adjustment method of the temperature control layer, the prior art also often uses an electric heating plate and a refrigerant pipe as a temperature control structure in other fields, so this application will not go into detail here.

[0052] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0053] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
