Description

Technical Field

[0001] The present invention relates to the technical field of natural gas, and in particular to a natural gas separation device and a method thereof. Background Art

[0002] Natural gas refers to a mixture of hydrocarbon and non-hydrocarbon gases stored in the strata. Its main component is methane, and it contains a small amount of nitrogen, carbon dioxide, hydrogen sulfide and other gases. Natural gas is a clean energy with the characteristics of high efficiency and cleanliness. After combustion, it mainly produces carbon dioxide and water, does not contain carbon monoxide, and has a lighter density than air. Once leaked, it will immediately spread upward and is not easy to accumulate to form explosive gas, so it is safer. Using natural gas as an energy source can reduce the use of coal and oil, greatly improve environmental pollution problems, reduce the emission of sulfur dioxide and nitrogen oxides, and help reduce the formation of acid rain and alleviate the global greenhouse effect. As a clean energy, natural gas is widely used. It is not only used for energy supply for residents and industry, but also shows great potential in the fields of automobile fuel. In addition, the exploitation and utilization of natural gas are of great significance to economic development and environmental improvement. The purpose of natural gas separation technology is to improve the purity and quality of natural gas to meet the requirements of transportation, processing and final use. Through these technologies, oil and water impurities in natural gas can be effectively separated, resource utilization can be improved, and corrosion of pipelines and equipment can be prevented to reduce pollution to the environment. In addition, high-purity nitrogen, oxygen, etc. can be obtained through cryogenic separation, which are widely used in the fields of petroleum, chemical industry, natural gas, etc.

[0021] The present invention also proposes a method for using the natural gas separation device, comprising the following steps:

[0022] S1: The feed pipe is fixedly connected to the collection equipment, and the collected natural gas is transported into the tank. Under the thrust of the collection equipment, the natural gas is pre-processed through the pre-processing box at the feed pipe. The decomposition net cooperates with the thrust to release the natural gas mixed in the soil. The released gas flows out through the upper grid to avoid re-mixing with the soil. The decomposed soil is more finely broken, which is convenient for subsequent corresponding treatment.

[0023] S2: The baffles 1 and 2 in the tank screen and separate the decomposed soil through the multiple holes 1 and the multiple holes 2, and divide the soil in front of the baffle 1 and between the baffle 2 to fully volatilize the natural gas contained therein. At the same time, the fixed plate blocks the flow speed to prevent the flow speed from being too fast to damage the multiple filters at the rear and affect the service life. In addition, the gas diffused in the tank is filtered to further improve the separation effect.

[0024] S3: Start the motor to drive the semicircular gear and the rectangular rack to operate, and drive the driving rod to move synchronously through the connection base fixedly connected above. At the same time, multiple connecting handles 2 make the same movement, and multiple sealing rubber nets on the protective plate protect the facilities in the protective plate to prevent the soil above from damaging it and affecting its operation. Multiple connecting handles 2 slide along multiple T-slots through adjusting shafts and multiple T-sliders to support and guide the driving rod, thereby increasing the service life of the driving rod. At the same time, the driving rod drives multiple fixed arc plates on multiple connecting handles 1 to move synchronously, and drives the dredging plates 1 and dredging plates 2 fixedly connected thereto to move synchronously, and cooperates with multiple dredging cones to dredge multiple holes 1 and multiple holes 2, which can effectively avoid blockage and increase the separation effect. Multiple balls and multiple rollers on the dredging plates 1 and 2 slide along the slide groove 1, and are guided and supported, which can effectively increase the dredging effect.

[0025] S4: The separated natural gas is discharged through the outlet pipe and collected. The baffle plate 3 located at the outlet pipe is stored in the storage box by operating the handle, which is convenient for centralized processing of the separated debris. The handle can be hung above the storage box to prevent the baffle plate 3 from sliding suddenly and causing unnecessary losses.

[0026] In the present invention, the beneficial effects of the natural gas separation device and method are as follows:

[0027] (1) Use multiple screening devices to separate the extracted natural gas to different degrees to increase the effect of the separation operation.

[0028] (2) The extracted natural gas is initially processed in a pretreatment box, the natural gas mixed in it is released, and flows out through the exhaust hole above, so that the mixed natural gas floats above the equipment and is further processed.

[0029] (3) The multiple holes on baffle plate 1 and baffle plate 2 can block and screen the gas or chemical components mixed therein.

[0030] (4) Different elements in the gas can be filtered multiple times through multiple filters, making the filtered natural gas purer.

[0031] The present invention can perform preliminary separation operations on the mined natural gas through a pretreatment box and release the gas mixed inside, and screen, filter and block the gas mixed therein to varying degrees through subsequent multiple devices, thereby increasing the effect of natural gas separation, and clean the equipment through multiple dredging plates to avoid blockage caused by long-term operation.

4. A method for using a natural gas separation device, wherein the natural gas separation device is the natural gas separation device according to claim 3, characterized in that: The following steps are involved: S1: The feed pipe (2) is fixedly connected to the collection equipment, and the collected natural gas is transported to the tank (8). Under the action of the thrust of the collection equipment, the natural gas is pre-processed through the pre-processing box (11) at the feed pipe (2). The decomposition net (13) cooperates with the thrust to release the natural gas mixed in the soil. The released gas flows out through the upper grid (61) to avoid re-mixing with the soil. The decomposed soil is more finely divided, which is convenient for subsequent corresponding treatment. S2: The baffle plate 1 (14) and the baffle plate 2 (16) in the tank body (8) screen and separate the decomposed soil through the plurality of holes 1 (17) and the plurality of holes 2 (18), and divide the soil in front of the baffle plate 1 (14) and between the baffle plate 2 (16), so as to fully volatilize the natural gas contained therein. At the same time, the fixed plate (15) blocks the flow speed to prevent the flow speed from being too fast and causing damage to the plurality of filter screens (19) at the rear, thereby affecting the service life. In addition, the gas diffused in the tank body (8) is filtered to further improve the separation effect. S3: The motor (31) is started to drive the semicircular gear (35) and the rectangular rack (36) to operate, and the driving rod (38) is driven to move synchronously through the connection base (37) fixedly connected above. At the same time, the plurality of connecting handles (39) make the same movement, and the plurality of sealing rubber nets (34) on the protective plate (12) protect the facilities in the protective plate (12) to prevent the soil above from damaging them and affecting their operation. The plurality of connecting handles (39) slide along the plurality of T-slots (41) through the adjustment shaft (42) and the plurality of T-slide blocks (43) to support and guide the driving rod (38), thereby increasing the driving rod ( 38), and at the same time, the driving rod (38) drives the multiple fixed arc plates (23) on the multiple connecting handles (24) to move synchronously, and drives the dredging plate (21) and the dredging plate (25) fixedly connected thereto to move synchronously, and cooperates with the multiple dredging cones (22) to perform dredging operations on the multiple holes (17) and the multiple holes (18), which can effectively avoid blockage and increase the separation effect, and the multiple rolling balls (28) and the multiple rollers (30) on the dredging plate (21) and the dredging plate (25) slide along the slide groove (10), and are guided and supported, which can effectively increase the dredging effect; S4: The separated natural gas is discharged through the outlet pipe (3) and collected. The baffle plate 3 (56) located at the outlet pipe (47) is stored in the storage box (48) by operating the handle (52), so that the separated debris can be centrally processed. The handle (52) can be hung above the storage box (48) to prevent the baffle plate 3 (56) from sliding suddenly and causing unnecessary losses.
