Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas recovery equipment, and in particular to an oil and gas recovery skid-mounted device. Background Art

[0002] The oil and gas recovery skid includes an oil and gas recovery device and a skid base for installing the oil and gas recovery skid. The oil and gas recovery skid is widely used as a new type of environmental protection equipment. According to the principle classification, there are many processes on the market, such as condensation method, adsorption method, absorption method, membrane separation method, etc., and the final product is also presented in various forms accordingly.

[0003] Due to the uneven production and manufacturing levels of various companies, the oil and gas recovery skids they produce cannot be flexibly adjusted according to site conditions, and a portion of the workload needs to be reserved for construction after the equipment arrives at the site. This leads to difficulties in user on-site management, a large amount of construction work, and a long equipment installation time, which affects the user's on-site personnel and daily work arrangements, and the conditions for completion acceptance are delayed.

[0004] On the other hand, the existing oil and gas recovery skid only has two adsorption towers for adsorption work, that is, the oil and gas transported by the pipeline are only processed at one level, such as Figure 1 As environmental protection requirements become increasingly stringent, the oil and gas recovery devices built previously can no longer meet the needs. Only a very small number of the original equipment can be upgraded and renovated on their existing basis to meet the new emission standards, but most of the oil and gas recovery devices can only be discarded, which not only increases the factory's production costs, but also causes a great deal of waste.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 2 As shown, an embodiment of the present invention proposes an oil and gas recovery skid-mounted device, including: a first module, which includes a first adsorption tower 1, a second adsorption tower 2 and a secondary adsorption unit respectively connected to the output ends of the first adsorption tower 1 and the second adsorption tower 2, the secondary adsorption unit includes a third adsorption tower 3, the third adsorption tower 3 is different from the first adsorption tower 1 and the second adsorption tower 2 in that the third adsorption tower 3 has a different filler and has the function of filtering finer particles, the third adsorption tower 3 is connected to a vacuum pump 5 through a pipeline 4, the vacuum pump 5 is used to extract oil and gas out of the third adsorption tower 3, the function of the vacuum pump 5 is an existing oil and gas recovery skid commonly used equipment, the first adsorption tower 1 and the second adsorption tower 2 are used to receive the oil and gas input by the pipeline 4; by connecting the pipeline 4 to the first The second module is connected to the modules, the second module includes a vacuum pump 5, a recovery tower 6 and a pipeline pump 7 installed on the pipeline 4, the vacuum pump 5 is used to evacuate the first module, the recovery tower 6 is used to receive the oil and gas processed by the first absorption tower 1, the second absorption tower 2 and the secondary adsorption unit, and the oil and gas return to the bottom of the recovery tower 6 after convection with the liquid in the recovery tower 6, and are finally discharged; and a skid 8 for installing the first module and the second module, the skid 8 includes a steel connector 81 and a connecting assembly 82, the steel connector 81 is fixed to the ground, different numbers of steel connectors 81 can be selected according to the site during specific installation, and each steel connector 81 is connected end to end through the connecting assembly 82.

[0028] Furthermore, if Figure 3 As shown, the steel connecting member 81 includes a plurality of H-shaped steels connected end to end, the H-shaped steels surround the skid seat 8 of a frame structure, and at least two H-shaped steels are fixed to the ground, such as Figure 3 If the skid 8 is a rectangular structure, the wide side can be fixed to the ground by bolts, and the two opposite long sides can be connected to H-shaped steels of different lengths using the connecting assembly 82. If the skid 8 is a polygonal structure, two or more H-shaped steels can be fixed to the ground. Due to site restrictions, H-shaped steels of different lengths need to be selected for connection. The use of the connecting assembly 82 can make full use of H-shaped steels of different lengths to achieve rapid installation and removal. Figure 4The connecting assembly 82 includes a mounting seat 821, a limit platform 822, a locking column 823 and a rotating component 83, and a locking column 823 is respectively connected to the two sides of the rotating component 83. The two locking columns 823 respectively pass through the limit platform 822 located on each side and fixed on the mounting seat 821. When in use, the rotating component 83 is rotated, and the two locking columns 823 can respectively extend into the locking holes opened on the steel connecting member 81, and when the rotating component 83 is operated in the reverse direction, the two locking columns 823 can be respectively disengaged from the locking holes. Since there are two opposing steel connecting members 81 on the pry seat 8 fixed to the ground, the overall fixation of the pry seat 8 can be achieved. Compared with the method of using multiple bolts to fix each steel connecting member 81 in the prior art, the connection method of the present invention is easy to disassemble and faster to install, which can save work time to a great extent.

[0029] The present invention also provides another embodiment, see Figure 5 The steel connector 81 includes a plurality of H-shaped steels connected end to end, the H-shaped steels enclose a skid 8 of a frame structure, and at least two H-shaped steels are fixed to the ground; in this embodiment, the connection assembly 82 includes a limit table 822, a locking column 823, and a rotating component 83. Different from the previous embodiment, only one side of the rotating component 83 is connected with a locking column 823, and the locking column 823 passes through the limit table 822 fixed on the steel connector 81. The limit table 822 is fixed to the steel connector 81, so that after operating the rotating component 83, the locking column 823 can be extended into the locking hole opened on the steel connector 81, and the locking column 823 can be separated from the locking hole when the rotating component 83 is reversely operated. The connection assembly 82 provided in this embodiment is directly fixed on the steel connector 81, and the structure is simpler and easy to operate. In actual use, the connection assembly 82 can be selected according to different steel connectors 81.

[0030] Furthermore, the rotating component 83 includes a push handle 831, a fixing portion 832 and a connecting rod. The push handle 831 is in an "L" shape as a whole, and the push handle 831 is movably connected to the fixing portion 832 fixed on the mounting seat 821. One end of the push handle 831 is hinged to a locking column 823, and the other end of the push handle 831 is hinged to the connecting rod. The connecting rod with the locking column 823 connected to one side does not have a connecting rod, and the end of the connecting rod away from the push handle 831 is hinged to another locking column. The push handle 831 described in 823 has connecting heads extending away from the push handle 831 on both sides, and the two connecting heads are respectively located in the sliding grooves opened on the fixed part 832, so that when the push handle 831 is rotated, the two connecting heads can move in the sliding grooves, and the ends of the connecting rod and the push handle 831 and the locking column 823 hinged together will approach each other, and the two locking columns 823 can approach each other to disengage from the locking holes on the steel connecting piece 81, or move away from each other to be inserted into the locking holes on the steel connecting piece 81.

[0031] Further, from Figure 5It can be seen that the push handle 831 includes a connecting section 8311, a free section 8312 and a locking component 84. The free section 8312 is hinged to the connecting section 8311, and the end of the free section 8312 is inserted into the two connecting plates at the end of the connecting section 8311. In order to facilitate the fixation of the free section 8312 and the connecting section 8311, the locking component 84 is installed at one end of the free section 8312 close to the connecting section 8311. The locking component 84 passes through the rear end of the free section 8312 and is inserted into the hole opened on the connecting section 8311. When the locking component 84 is operated, the end of the locking component 84 can be detached from the hole, so that the free section 8312 can be rotated, thereby The end of the free section 8312 is connected to the limit platform 822 to prevent it from being rotated due to human collision due to its excessive height; after the locking column 823 is inserted into the locking hole, a locking component 84 is also installed at the end of the free section 8312 away from the connecting section 8311, and the structure is the same as the locking component 84 at the end of the free end close to the connecting section 8311, so that when the free section 8312 is rotated, the locking component 84 at the end away from the connecting section 8311 can be inserted into the limit hole 8221 opened on the limit platform 822. In this way, when the end of the free section 8312 is inserted into the limit hole 8221, the connecting section 8311 can be prevented from rotating, thereby preventing the locking column 823 from detaching from the locking hole in an accident. The locking component 84 includes a locking pin 841 and a spring 842. The locking pin 841 passes through the installation cavity 8313 on the free section 8312, and the locking pin 841 passes through the spring 842 located in the installation cavity 8313. One end of the spring 842 abuts against the limiting ring 843 on the locking pin 841, and the other end of the spring 842 abuts against the inner wall of the installation cavity 8313, so that the end of the locking pin 841 can extend out of the installation cavity 8313. When the operator manually pulls the other end of the locking pin 841, one end of it can be pulled into the installation cavity 8313.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
