Description

Technical Field

[0001] The utility model mainly relates to the technical field of etherified liquefied gas production, in particular to a raw material buffer device for etherified liquefied gas fractionation. Background Art

[0002] Liquefied petroleum gas is a colorless volatile liquid obtained by pressurizing and cooling natural gas or petroleum to liquefy it in an oil refinery.

The main components of liquefied petroleum gas obtained from an oil refinery are one or two of propane, propylene, butane, and butene, and it is also mixed with a small amount of pentane, pentene and trace amounts of sulfide impurities. Therefore, there are many processing procedures for liquefied gas, such as the fractionation of etherified liquefied gas, but raw material buffering is required when the etherified liquefied gas is fractionated.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0020] The following describes an embodiment of the utility model based on its overall structure. Example

[0021] Please refer to the attached Figure 1 , 2 As shown in Figures 4 and 5, in a preferred embodiment of the utility model, a raw material buffer device for post-ether liquefied gas fractionation includes a buffer tank 10, an air inlet 11 is embedded in the top of the buffer tank 10, a valve component 12 is embedded in the inner wall of the air inlet 11, a first buffer component 13 is embedded in the bottom of the air inlet 11, and three air outlets 14 are embedded in the outer wall of the buffer tank 10. The valve component 12 includes a solenoid valve 121 arranged on the outer wall of the air inlet 11, and the solenoid valve 121 can control the valve to allow the raw material to intermittently enter the interior of the buffer tank 10 from the conveying pipeline. The first buffer component 13 includes a first buffer plate 131 embedded in the top of the buffer tank 10, the top of the first buffer plate 131 is elastically connected to the buffer tank 10 through a rebound component 132, and a plurality of buffer grooves are embedded in the side wall of the first buffer plate 131. The rebound component 132 includes a plurality of first springs 1321 embedded in the top of the buffer tank 10, and one end of the first spring 1321 is fixedly connected to the top of the first buffer plate 131.

[0022] It should be noted that, in the present embodiment, the raw material that needs to be buffered enters from the air inlet 11, and the solenoid valve 121 intermittently opens the valve 122, so that the raw material that needs to be buffered intermittently enters the interior of the buffer tank 10, and at this time impacts the first buffer plate 131. The surface of the first buffer plate 131 has a number of through holes that also buffer and slow down the raw material. However, because the speed of the raw material just entering the buffer tank 10 is too high, the first buffer plate 131 will be pushed, and the top of the first buffer plate 131 is movably connected to the interior of the buffer tank 10 through the first spring 1321. At this time, the first spring 1321 is pulled by the first buffer plate 131. When no raw material passes through the first buffer plate 131, the first spring 1321 restores its elastic force, and the first buffer plate 131 returns to its original position.

[0023] Please refer to the attached Figure 3 , 4 As shown in the figure, in a preferred embodiment of the utility model, a first fixing rod 15 is fixedly connected to the top of the inner wall of the buffer tank 10, a second buffer component 16 is provided at the bottom of the first fixing rod 15, a third buffer component 17 is embedded in the bottom of the buffer tank 10, the second buffer component 16 includes a second buffer plate 161 fixed to the bottom of the first fixing rod 15, a second fixing rod 162 is fixedly connected to the bottom of the second buffer plate 161, a third buffer plate 163 is fixedly connected to the bottom of the second fixing rod 162, a plurality of buffer grooves are embedded in the side walls of the second buffer plate 161 and the third buffer plate 163, and the top surfaces are both conical surfaces, the third buffer component 17 includes a second spring 171 embedded in the inner bottom wall of the buffer tank 10, one end of the second spring 171 is fixedly connected to the bottom of the fourth buffer plate 172, and the central bottom of the fourth buffer plate 172 is embedded in the inner bottom wall of the buffer tank 10.

[0024] It should be noted that, in the present embodiment, when the raw material reaches the second buffer plate 161 and the third buffer plate 163, because the tops of the second buffer plate 161 and the third buffer plate 163 are slightly raised surfaces and have buffer holes, the raw material is decelerated for a second time when passing through the second buffer plate 161 and the third buffer plate 163, and then reaches the fourth buffer plate 172. When it hits the fourth buffer plate 172, the second spring 171 is squeezed. While the fourth buffer plate 172 squeezes the spring, the final buffering work of the raw material is completed, and then it can be discharged from the air outlet 14. Then the second spring 171 restores its elastic force, and the fourth buffer plate 172 is restored to its original position for the next buffering.

[0025] The working principle of the utility model is:

[0026] The raw material that needs to be buffered enters from the air inlet 11, and the solenoid valve 121 intermittently opens the valve 122, so that the raw material that needs to be buffered intermittently enters the interior of the buffer tank 10, and at this time impacts the first buffer plate 131. The surface of the first buffer plate 131 has a plurality of through holes that also buffer and slow down the raw material. However, because the speed of the raw material just entering the buffer tank 10 is too high, the first buffer plate 131 will be pushed. The top of the first buffer plate 131 is movably connected to the interior of the buffer tank 10 through the first spring 1321. At this time, the first spring 1321 is pulled by the first buffer plate 131. When no raw material passes through the first buffer plate 131, the first spring 1321 restores its elastic force, and the first buffer plate 13 1 returns to its original position. At this time, the raw material reaches the second buffer plate 161 and the third buffer plate 163. Because the tops of the second buffer plate 161 and the third buffer plate 163 are slightly raised surfaces and have buffer holes, the raw material is decelerated for a second time when passing through the second buffer plate 161 and the third buffer plate 163, and then reaches the fourth buffer plate 172. When it hits the fourth buffer plate 172, it squeezes the second spring 171. When the fourth buffer plate 172 squeezes the spring, the final buffering work of the raw material is completed, and then it can be discharged from the air outlet 14. Then the second spring 171 restores its elastic force, and the fourth buffer plate 172 is restored to its original position for the next buffering.
