Description

Technical Field

[0001] This utility model relates to the field of natural gas processing technology, specifically to a high-efficiency and energy-saving natural gas processing device. Background Technology

[0002] Natural gas processing primarily involves the extraction, processing, and refining of natural gas, aiming to improve its quality and value. Its core includes removing impurities from natural gas, such as moisture, sulfides, and carbon dioxide, as well as separating it into different components, such as liquefied natural gas (LNG), ethylene, and propylene. Natural gas processing also includes processes such as gas dehydration, desulfurization, decarbonization, liquefaction, and compression to ensure that natural gas meets standards for transportation and use.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Common natural gas processing equipment typically removes moisture and other impurities by lowering the temperature of the natural gas. However, natural gas processing equipment may not have the corresponding pretreatment structure, which may result in the natural gas being too hot. This would increase the time required for the natural gas to be cooled before entering the equipment, thus affecting work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency and energy-saving natural gas processing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving natural gas processing device, comprising a cold box body, a box cover installed on the top of the cold box body, natural gas pipelines horizontally running through both sides of the cold box body, a cooling sleeve installed on the lower part of one side of the cold box body outside the natural gas pipeline, a partition installed on the inner side of the cold box body, a heat exchanger installed on one side of the top of the partition, a water outlet pipe installed on the other side of the top of the partition, a water pump installed on the top of the water outlet pipe, a water inlet pipe installed on one side of the water pump, and a water inlet pipe installed on the lower part of the outer side of the cooling sleeve.

[0007] More preferably, the lower parts of both sides of the cold box body are provided with slots, and the diameter of the slots is consistent with the outer diameter of the natural gas pipeline, and a sealing gasket is installed at the connection between the slots and the natural gas pipeline.

[0008] More preferably, flanges are installed on both sides of the natural gas pipeline.

[0009] More preferably, a sealing gasket is installed at the connection between one side of the cooling sleeve and the natural gas pipeline.

[0010] More preferably, the inner wall of the cooling sleeve is spiral-shaped.

[0011] More preferably, the top of the partition plate has a plurality of through holes evenly distributed.

[0012] More preferably, the diameter of the outlet pipe is larger than the diameter of the inlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This natural gas processing device, through a cooling sleeve and a water pump, enables cooling water to cool the natural gas inside the pipeline. The spiral inner wall design increases the time the cooling water spends outside the pipeline, thus increasing cooling efficiency. This allows for effective pretreatment of the natural gas before it enters the cold box, reducing the time the cooling water inside the cold box is needed to cool the pipeline and improving overall efficiency. Furthermore, the cooling water can be effectively recycled, preventing waste and contributing to energy savings. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a high-efficiency and energy-saving natural gas processing device, including a cold box body 1, a box cover 2 installed on the top of the cold box body 1, natural gas pipelines 3 horizontally installed on both sides of the cold box body 1, a cooling sleeve 4 installed on the lower part of one side of the cold box body 1 outside the natural gas pipeline 3, a partition 5 installed on the inner side of the cold box body 1, a heat exchanger 6 installed on one side of the top of the partition 5, a water outlet pipe 7 installed on the other side of the top of the partition 5, a water pump 8 installed on the top of the water outlet pipe 7, a water inlet pipe 9 installed on one side of the water pump 8, and a water inlet pipe 10 installed on the lower part of the outer side of the cooling sleeve 4.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, slots are provided on the lower parts of both sides of the cold box body 1, and the diameter of the slots is consistent with the outer diameter of the natural gas pipeline 3. A sealing gasket is installed at the connection between the slots and the natural gas pipeline 3.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, flanges are installed on both sides of natural gas pipeline 3.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sealing gasket is installed at the connection between one side of the cooling sleeve 4 and the natural gas pipeline 3.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner wall of the cooling sleeve 4 is spiral-shaped.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top of the partition 5 has several through holes evenly distributed.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the diameter of the outlet pipe 7 is larger than the diameter of the inlet pipe 9.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the working process of this high-efficiency and energy-saving natural gas processing device is as follows:

[0029] First, connect the flanges at both ends of the natural gas pipeline 3 to the inlet pipe and the processing device, respectively. Then, natural gas is discharged into the natural gas pipeline 3 through the inlet pipe. At this time, the water pump 8 can be turned on. The water pump 8 will draw the cooling water inside the cold box body 1 into the outlet pipe 7, and then into the cooling sleeve 4 through the smaller diameter inlet pipe 9. This increases the water pressure, thereby enabling more efficient cooling of the natural gas pipeline 3. The spiral inner wall design of the cooling sleeve 4 increases the time the cooling water stays outside the natural gas pipeline 3, further increasing the cooling efficiency. The sealing gasket maintains effective sealing to prevent cooling water overflow. The cooled water will then flow through the inlet pipe... Water pipe 10 enters the interior of the cold box body 1 to achieve a recycling effect, increasing energy efficiency. At this time, heat exchanger 6 can be opened to perform heat exchange treatment on the cooling water, ensuring that the cooling water can effectively cool. At this time, the pre-treated natural gas will enter the natural gas pipe 3 inside the cold box body 1 through the natural gas pipe 3, and will be further cooled by the cooling water inside the cold box body 1, making the natural gas processing more efficient. After cooling, the natural gas will enter the processing device through the natural gas pipe 3 for subsequent processing. The natural gas pipe 3 and the cold box body 1 will maintain an effective seal through a sealing gasket. The design of the through hole at the top of the partition 5 allows the staff to open the box cover 2 to add cooling water inside.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
