Description

Technical Field

[0001] The utility model relates to the field of gas storage buffer tanks, in particular to a gas storage buffer tank with a gas-liquid separation device. Background Art

[0002] The water content of instrument gas and nitrogen, the common medium in chemical production, requires strict control. The traditional gas buffer tank adopts the method of bottom inlet and top outlet (such as Figure 2 As shown, air is taken in from the lower air inlet 2 and then discharged from the top connection port 4) to separate gas and liquid. The water content of the compressed gas falls, while the gas rises to achieve separation. If the separation of the two is not sufficient, it is easy for the gas to carry some liquid, which poses a safety hazard when it is supplied to downstream workshops. Especially in winter, the instrument gas contains more water, which can easily cause the gas source pipe to be blocked for a long time, and the pneumatic valve to malfunction, causing production accidents. In addition, the gas is discharged directly from the top of the gas storage buffer tank 1. If the gas consumption of the downstream production process suddenly increases, the gas storage buffer tank will not be able to stabilize the pressure, affecting safe production. Utility Model Content

[0003] In order to solve the above-mentioned problems, the utility model provides a gas storage buffer tank with a gas-liquid separation device.

[0004] The utility model is realized through the following technical solutions:

[0005] A gas buffer tank with a gas-liquid separation device includes a gas buffer tank and a top connecting port and an air inlet respectively arranged at the upper and lower ends thereof, a stabilizing air guide pipe is arranged inside the gas buffer tank, the inlet of the stabilizing air guide pipe is located at the top of the gas buffer tank, and the outlet of the stabilizing air guide pipe extends downward and is connected and fixed to the gas outlet at the lower side end of the gas buffer tank.

[0006] Further optionally, the stable air guide tube includes an inclined tube and a vertical tube that are connected together from top to bottom, and the top of the inclined tube is opposite to the top connecting port.

[0007] Further optionally, the side portion of the vertical pipe is connected and fixed to the inner wall of the gas storage buffer tank via a fixing frame.

[0008] Further optionally, a capsule-type buffer is installed on the top connection port.

[0009] Further optionally, a drain port is provided at the bottom of the gas storage buffer tank, and a control valve is installed on the drain port.

[0010] Compared with the existing technology, the beneficial effects of the utility model are as follows: the utility model arranges a stable air guide pipe inside the gas storage buffer tank, changes the position of the gas outlet of the gas storage buffer tank, and changes it to a bottom outlet mode, thereby extending the residence time of the gas in the gas storage buffer tank, further separating the gas and liquid, and at the same time installing a bladder buffer at the top outlet of the original gas storage buffer tank, which is beneficial to the stability of the gas supply pressure of the storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the structure of the utility model;

[0012] Figure 2 It is a schematic diagram of the prior art of this utility;

[0013] In the figure: an air storage buffer tank 1, an air inlet 2, a manhole 3, a top connection port 4, a vertical pipe 5, an inclined pipe 6, an air outlet 7, a fixing frame 8, a bladder buffer 9, and a liquid discharge port 10. DETAILED DESCRIPTION

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0015] like Figure 1 As shown, a gas storage buffer tank with a gas-liquid separation device comprises a gas storage buffer tank 1 and a top connection port 4 and an air inlet 2 respectively arranged at the upper and lower ends thereof, a stable air guide pipe is arranged inside the gas storage buffer tank 1, the inlet of the stable air guide pipe is located at the top of the gas storage buffer tank 1, and the outlet of the stable air guide pipe extends downward and is connected and fixed to the gas outlet 7 at the lower part of the side end of the gas storage buffer tank 1;

[0016] The gas outlet position of the gas storage buffer tank 1 is changed to a bottom outlet mode, and a stable air guide pipe is installed on the top of the gas storage buffer tank 1 and connected to the lower gas outlet, which prolongs the retention time of the gas in the gas storage buffer tank and further separates the gas and liquid. In addition, the use of the air guide pipe to discharge the gas is more conducive to the stability of the gas supply pressure of the storage tank.

[0017] The stable air duct includes an inclined tube 6 and a vertical tube 5 connected together from top to bottom. The inclined tube 6 makes the inlet of the stable air duct located at the central top connecting port 4 to ensure that the air intake is more uniform and stable. The top of the inclined tube 6 faces the top connecting port 4.

[0018] The side of the vertical pipe 5 is connected and fixed to the inner wall of the gas storage buffer tank 1 through a fixing frame 8, so the installation is more convenient.

[0019] A bladder-type buffer 9 is installed on the top connection port 4. By installing the bladder-type buffer 9 on the original top-outlet gas storage buffer tank 1, the pressure fluctuation caused by the change at the rear end of the gas storage buffer tank 1 can be eliminated, thereby ensuring the stability of the gas pressure in the gas storage buffer tank 1.

[0020] A drain port 10 is provided at the bottom of the gas storage buffer tank 1, and a control valve is installed on the drain port 10. After liquid accumulates at the bottom of the gas storage buffer tank 1 for a long time, the control valve on the drain port 10 needs to be opened to drain water to ensure the stability of the use of the gas storage buffer tank 1.

[0021] The implementation principle of a gas storage buffer tank with a gas-liquid separation device in the embodiment of the present application is:

[0022] The compressed gas generated by the compressor enters the gas buffer tank 1 along the air inlet 2. The moisture in the gas falls due to gravity and gathers at the bottom of the gas buffer tank 1. The gas enters along the inclined pipe 6 at the top of the stable air guide pipe in the gas buffer tank 1, and is discharged from the gas outlet 7 at the bottom of the gas buffer tank 1 through the vertical pipe 5 to enter the downstream production line. The stable air guide pipe can extend the retention time of the gas in the gas buffer tank 1, further separate the gas and liquid, greatly reduce the moisture in the gas, avoid subsequent pipeline freezing in winter, and fundamentally eliminate production accidents caused by malfunction of the pneumatic valve;

[0023] At the same time, due to the setting of the stable air guide pipe, the gas pressure entering the stable air guide pipe in the gas storage buffer tank 1 is more stable. In addition, the bladder-type buffer 9 is set on the top of the gas storage buffer tank 1. The compressed gas inside the bladder-type buffer 9 is used as the energy storage medium, and the inflation pressure inside the airbag is used to adjust the working pressure range and shock wave absorption capacity of the buffer tank. When the gas pressure inside the airbag reaches the preset value, the expansion and contraction of the airbag can effectively slow down and eliminate the pressure pulsation and liquid shock wave generated in the system, thereby protecting the safety and stability of the system equipment and components, and realizing the overall pressure of the gas storage buffer tank 1, and the gas supply pressure of the tank is more stable.
