Description

Technical Field

[0001] This application relates to the technical field of acetylene filling, and more specifically, to an acetylene filling system. Background Art

[0002] As a raw material for acetylene carbon black, acetylene is often industrially produced by the calcium carbide method. Acetylene gas is also often filled into cylinders to produce dissolved acetylene for sale. However, in the production process of acetylene, it is necessary to carry out impurity removal treatments such as pickling and alkali washing on the acetylene gas, which causes a large amount of moisture to be mixed into the acetylene gas. As a result, the moisture content in the acetylene gas extracted by the compressor from the gas holder is relatively large. During the production of dissolved acetylene, the moisture in the acetylene gas may damage the compressor and may also cause the moisture content in the product to be too large, resulting in unqualified products. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide an acetylene filling system, which can reduce the moisture in the acetylene gas entering the compressor and ensure the safe and stable operation of the equipment.

[0004] In a first aspect, the embodiments of this application provide an acetylene filling system, which includes: an acetylene gas holder, a dryer, an acetylene compressor, and a filling row. The acetylene gas holder has an exhaust port, the dryer has an inlet and an outlet, the acetylene compressor has a first inlet and an exhaust port, and the filling row has an inlet. The exhaust port of the acetylene gas holder is connected to the inlet of the dryer through a pipeline, the outlet of the dryer is connected to the first inlet of the acetylene compressor, and the exhaust port of the acetylene compressor is connected to the inlet of the filling row. At least one section of the pipeline connecting the exhaust port of the acetylene gas holder and the inlet of the dryer is a U-shaped pipe, the two openings of the U-shaped pipe face upward, and a drain port is provided at the bottom of the U-shaped pipe.

[0005] In the above implementation process, the acetylene filling system of this application adds a U-shaped pipe to the pipeline between the acetylene gas holder and the dryer, and makes the two openings of the U-shaped pipe face upward. When the acetylene gas containing a large amount of moisture (or a mixture of acetylene gas and moisture) coming out of the acetylene gas holder passes through the pipeline of the U-shaped pipe, the moisture will stay at the bottom of the U-shaped pipe due to gravity, while the acetylene gas can enter the dryer through the U-shaped pipe. The moisture stored at the bottom of the U-shaped pipe can be discharged through the drain port. Before the acetylene gas enters the acetylene compressor, it is dried by the dryer again, which can ensure that the acetylene gas entering the acetylene compressor contains less moisture, thereby ensuring the safe and stable operation of the equipment.

[0006] In a possible implementation, the exhaust port of the acetylene gas holder is connected to the U-shaped pipe through a straight pipeline, the position of the exhaust port of the acetylene gas holder is higher than the position of the U-shaped pipe, and the straight pipeline is arranged obliquely.

[0007] In the above implementation process, when the acetylene gas containing a large amount of moisture (or a mixture of acetylene gas and moisture) coming out of the acetylene gas holder flows in the pipeline, some moisture may be deposited at the bottom of the pipeline. By arranging the straight pipeline connecting the exhaust port of the acetylene gas holder and the U-shaped pipe in an inclined manner, the moisture deposited at the bottom of the pipeline can flow towards the U-shaped pipe due to the action of gravity, and finally be stored at the bottom of the U-shaped pipe and discharged through the drain port at the bottom of the U-shaped pipe.

[0008] In a possible implementation, the acetylene filling system further includes a water storage device, and the water storage device is connected to the drain port of the U-shaped pipe.

[0009] In the above implementation process, the water storage device is used to collect the moisture stored at the bottom of the U-shaped pipe, preventing too much moisture stored at the bottom of the U-shaped pipe from blocking the U-shaped pipe.

[0010] In a possible implementation, the acetylene filling system further includes a water seal, and the water seal is arranged between the acetylene gas holder and the dryer.

[0011] In the above implementation process, the water seal plays a role in preventing fire, and the acetylene gas is directly introduced into the water in the water seal for sealing.

[0012] In a possible implementation, the acetylene filling system further includes a liquid-gas separator, and the liquid-gas separator is arranged between the water seal and the dryer.

[0013] In the above implementation process, the liquid-gas separator is used to preliminarily separate the acetylene gas after passing through the water seal into gas and water.

[0014] In a possible implementation, the acetylene filling system further includes a drying tower, which has an air inlet and a first exhaust port. The air inlet of the drying tower is connected to the exhaust port of the acetylene compressor, and the first exhaust port of the drying tower is connected to the air inlet of the filling row.

[0015] In the above implementation process, the drying tower is used to dry the acetylene gas compressed by the acetylene compressor and then send it to the filling row for gas filling.

[0016] In a possible implementation, the drying tower further has a second exhaust port, and the acetylene compressor has a second air inlet. The second exhaust port is connected to the second air inlet of the acetylene compressor.

[0017] In the above implementation process, after drying the acetylene gas compressed by the acetylene compressor in the drying tower, chemical analysis is required. If the chemical analysis is qualified, the acetylene gas is sent to the filling row through the first exhaust port for gas filling. If the chemical analysis is unqualified, the acetylene gas needs to enter the acetylene compressor through the second exhaust port for re-compression of the acetylene compressor and re-drying of the drying tower until the chemical analysis is qualified and sent to the filling row for gas filling.

[0018] In a possible implementation, the acetylene filling system further includes a circulating water tank, the circulating water tank has a water outlet, and the water outlet of the circulating water tank is connected to the filling row through a spraying device.

[0019] In the above implementation process, the filling row is cooled by spraying cooling water through the spraying device.

[0020] In a possible implementation, the acetylene compressor further includes a circulating cooling device, the circulating water tank further has a water inlet, and the water inlet and water outlet of the circulating water tank are respectively connected to the circulating cooling device.

[0021] In the above implementation process, the acetylene compressor is cooled by the circulating cooling water in the circulating cooling device.

[0022] In a possible implementation, the acetylene filling system further includes a buffer tank, the filling row has an exhaust port, the acetylene gas holder has an inlet port, and the exhaust port of the filling row is connected to the inlet port of the acetylene gas holder through the buffer tank.

[0023] In the above implementation process, after completing the gas filling of the filling row, all valves of the system are closed, and the remaining gas enters the gas holder from the exhaust port of the filling row through the buffer tank, thereby recovering the remaining gas.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some but not all of the embodiments of this application. Components of the embodiments of this application described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of this application that is claimed, but merely represents selected embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0030] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] In the description of this application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings or the orientation or positional relationship when the product of this application is normally placed. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0032] In addition, terms such as "horizontal", "vertical", "hanging", etc. do not require the components to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0034] It is found in the present application that due to the large water content in the acetylene gas in the gas holder, especially in summer, the engine oil of the compressor will deteriorate every one to two days due to the incorporation of water, resulting in damage to the big bearing and small bearing sleeve of the compressor. If the engine oil of the compressor is changed every day, the operation is very cumbersome and there are also certain safety risks.

[0035] Please refer to Figure 1 , the embodiment of the present application provides an acetylene filling system 10, which includes: an acetylene gas holder 100, a dryer 200, an acetylene compressor 300, and a filling row 400.

[0036] Among them, the acetylene gas holder 100 is a device for storing acetylene gas, and the acetylene gas holder 100 has an exhaust port.

[0037] The dryer 200 is a device provided with a desiccant and used to remove the moisture in the acetylene gas. The dryer 200 has an air inlet and an air outlet.

[0038] It should be noted that the present application does not limit the type of desiccant, but the desiccant needs to be able to absorb the moisture in the acetylene gas without reacting with the acetylene gas. For example, the desiccant can be anhydrous calcium chloride, etc.

[0039] Optionally, the dryer 200 is provided with a first liquid level gauge 210, and the first liquid level gauge 210 is used to monitor the liquid height in the desiccant of the dryer 200.

[0040] Optionally, the dryer 200 also has a blowdown port, and the blowdown port of the dryer 200 is connected to a first blowdown pipeline 220.

[0041] When the liquid level in the desiccant in the dryer 200 is monitored by the first liquid level gauge 210 and is higher than the preset value, the drain port of the dryer 200 can be opened to discharge at least the liquid so that the liquid level in the desiccant in the dryer 200 is below the preset value.

[0042] The acetylene compressor 300 is a device for boosting low-pressure acetylene gas to high-pressure acetylene gas. The acetylene compressor 300 has a first intake port 301 and an exhaust port.

[0043] Optionally, the acetylene compressor 300 also has three drain ports, and the three drain ports of the acetylene compressor 300 are respectively connected to the first, second, and third drain pipes 310.

[0044] Optionally, the acetylene compressor 300 also has a first vent pipe 320, and a first valve 11 is provided on the first vent pipe 320.

[0045] The filling row 400 is a filling device for filling gas cylinders, and the filling row 400 has an intake port.

[0046] The exhaust port of the acetylene gas holder 100 is connected to the intake port of the dryer 200 through a pipe, the outlet port of the dryer 200 is connected to the first intake port 301 of the acetylene compressor 300, and the exhaust port of the acetylene compressor 300 is connected to the intake port of the filling row 400.

[0047] Please refer to Figure 1 and 2 At least one section of the pipe connecting the exhaust port of the acetylene gas holder 100 and the intake port of the dryer 200 is a U-shaped pipe 500, and the two openings of the U-shaped pipe 500 face upward. One opening of the U-shaped pipe 500 is the intake end, and the other opening is the outlet end. A drain port 501 is provided at the bottom of the U-shaped pipe 500. When the acetylene gas containing a large amount of moisture (or a mixture of acetylene gas and moisture) passes through the U-shaped pipe 500, it needs to pass through the entire pipe of the U-shaped pipe 500.

[0048] It should be noted that the acetylene filling system 10 of the present application does not limit the number of U-shaped pipes 500. In the embodiment shown in Figure 1 , only one U-shaped pipe 500 is provided between the exhaust port of the acetylene gas holder 100 and the intake port of the dryer 200. In some other embodiments of the present application, two, three or more U-shaped pipes 500 can also be provided between the exhaust port of the acetylene gas holder 100 and the intake port of the dryer 200. The multiple U-shaped pipes 500 are connected in series, and the acetylene gas containing a large amount of moisture (or a mixture of acetylene gas and moisture) needs to pass through the multiple U-shaped pipes 500 in sequence, and a drain port 501 is provided at the bottom of each U-shaped pipe.

[0049] Optionally, a second valve 12 is provided between the exhaust port of the acetylene gas holder 100 and the U-shaped pipe 500, and a third valve 13 and a flow meter 14 are provided between the U-shaped pipe 500 and the inlet of the dryer 200.

[0050] The acetylene filling system 10 of the present application adds a U-shaped pipe 500 to the pipeline between the acetylene gas holder 100 and the dryer 200, and makes the two openings of the U-shaped pipe 500 face upward. When the acetylene gas containing a large amount of moisture (or a mixture of acetylene gas and moisture) coming out of the acetylene gas holder 100 passes through the pipeline of the U-shaped pipe 500, the moisture will remain at the bottom of the U-shaped pipe 500 due to the action of gravity, while the acetylene gas can enter the dryer 200 through the U-shaped pipe 500. The moisture stored at the bottom of the U-shaped pipe 500 can be discharged through the drain port 501. Before entering the acetylene compressor 300, the acetylene gas is dried by the dryer 200 again, which can ensure that the acetylene gas entering the acetylene compressor 300 contains less moisture, thereby ensuring the safe and stable operation of the equipment.

[0051] Please refer to Figure 2 , optionally, the exhaust port of the acetylene gas holder 100 and the U-shaped pipe 500 are connected by a straight-through pipe 510. The position of the exhaust port of the acetylene gas holder 100 is higher than the position of the U-shaped pipe 500, and the straight-through pipe 510 is arranged obliquely.

[0052] When the acetylene gas containing a large amount of moisture (or a mixture of acetylene gas and moisture) coming out of the acetylene gas holder 100 flows in the pipeline, some moisture may be deposited at the bottom of the pipeline. By arranging the straight-through pipe 510 connecting the exhaust port of the acetylene gas holder 100 and the U-shaped pipe 500 obliquely, the moisture deposited at the bottom of the pipeline can flow towards the U-shaped pipe 500 due to the action of gravity, and finally be stored at the bottom of the U-shaped pipe 500 and discharged through the drain port 501 at the bottom of the U-shaped pipe 500.

[0053] Please continue to refer to Figure 1 , the acetylene filling system 10 further includes a water storage device 600, and the water storage device 600 is connected to the drain port 501 of the U-shaped pipe 500.

[0054] The water storage device 600 is used to collect the moisture stored at the bottom of the U-shaped pipe 500 to prevent the moisture stored at the bottom of the U-shaped pipe 500 from being too much and blocking the U-shaped pipe 500.

[0055] It should be noted that when multiple U-shaped tubes 500 are provided between the exhaust port of the acetylene gas holder 100 and the intake port of the dryer 200, a corresponding water storage device 600 can be provided near the drain port 501 at the bottom of each U-shaped tube 500. The drain port 501 at the bottom of each U-shaped tube 500 is connected to its corresponding water storage device. Alternatively, only one water storage device 600 can be provided for the acetylene filling system 10, and the drain ports 501 at the bottoms of all the U-shaped tubes 500 are connected to this water storage device 600.

[0056] Please continue to refer to Figure 1 , the acetylene filling system 10 further includes a water seal 700. The water seal 700 is a box device with a certain height of water inside, and the water seal 700 is provided between the acetylene gas holder 100 and the dryer 200.

[0059] Optionally, the water seal 700 also has a sewage outlet, and the sewage outlet of the water seal 700 is connected to the second sewage pipe 720.

[0060] When it is monitored by the second liquid level gauge 710 that the height of the water in the water seal 700 is higher than the highest preset value, the sewage outlet of the water seal 700 can be opened to discharge at least part of the water so that the height of the water in the water seal 700 is below the highest preset value.

[0061] Optionally, the acetylene filling system 10 further includes a liquid-gas separator 800, and the liquid-gas separator 800 is provided between the water seal 700 and the dryer 200.

[0062] The liquid-gas separator 800 is a device for liquid-gas separation, and is used for preliminary separation of gas and water of the acetylene gas after passing through the water seal 700.

[0063] Optionally, the liquid-gas separator 800 is provided with a third liquid level gauge 810, and the third liquid level gauge 810 is used to monitor the height of the water in the liquid-gas separator 800.

[0064] Optionally, the liquid-gas separator 800 also has a sewage outlet, and the sewage outlet of the liquid-gas separator 800 is connected to the second sewage pipe 720.

[0065] When it is monitored by the third liquid level gauge 810 that the height of the water in the liquid-gas separator 800 is higher than the preset value, the sewage outlet of the liquid-gas separator 800 can be opened to discharge at least part of the water so that the height of the water in the liquid-gas separator 800 is below the preset value.

[0066] Please continue to refer to Figure 1 , the acetylene filling system 10 further includes a drying tower 900. The drying tower 900 is a device for processing gases, which mainly uses adsorbents to remove moisture from the gases. The drying tower 900 has an air inlet and a first exhaust port 901. The air inlet of the drying tower 900 is connected to the exhaust port of the acetylene compressor 300, and the first exhaust port 901 of the drying tower 900 is connected to the air inlet of the filling row 400.

[0067] The drying tower 900 is used to dry the high-pressure acetylene gas compressed by the acetylene compressor 300, and then send it to the filling row 400 for gas filling. The drying tower 900 is based on the principle of natural balance of adjacent adsorbent loads. In the drying stage, the adsorbent adsorbs moisture from the gas with a higher pressure flowing through the adsorber. During regeneration, a small amount of dried gas with reduced pressure is recovered, and the adsorbent that has adsorbed moisture is regenerated through it. The adsorption heat released by the gas during drying is used to heat the regenerated gas that has been depressurized and cooled, improving the regeneration effect and reducing the consumption of regenerated gas.

[0071] After the drying tower 900 dries the acetylene gas compressed by the acetylene compressor 300, it needs to be analyzed by chemical tests. If the chemical test is qualified, the acetylene gas is sent to the filling row 400 through the first exhaust port 901 for gas filling. If the chemical test is unqualified, the acetylene gas needs to enter the acetylene compressor 300 through the second exhaust port 902 for re-compression by the acetylene compressor 300 and re-drying by the drying tower 900 until the chemical test is qualified and then sent to the filling row 400 for gas filling.

[0072] Optionally, a fifth valve 16 is provided between the second exhaust port 902 of the drying tower 900 and the second air inlet 302 of the acetylene compressor 300.

[0079] Optionally, the buffer tank 1100 further has a second vent pipe 1110, and a sixth valve 17 is provided on the first vent pipe 320.
