When a conventional flare system is deployed in a highly acidic gas field, liquid loading and iron sulfide powder deposition may occur in the flare system. Therefore, in the emptying process, the accumulated liquid and the powder flow out along with the natural gas, and the environment pollution is caused.
In order to solve this technical problem, the embodiments of the present disclosure provide a blowout prevention separator tank. Fig. 1 is a cut-away isometric view of the blowout prevention separator tank, which, as shown in fig. 1, includes a tank body 1, a baffle 2, and a drain 3.

The guide plate 2 is positioned in the diameter expanding section 12 and connected with the inner wall of the diameter expanding section 12, a first overflowing gap A is arranged between the lower edge of the guide plate 2 and the bottom of the inner wall of the diameter expanding section 12, a plurality of guide holes 21 are formed in the guide plate 2, the guide holes 21 penetrate through two opposite plate surfaces of the guide plate 2, and the guide plate inclines towards the bottom of the inner wall of the diameter expanding section 12 in the direction from the inlet section 11 to the outlet section 13. The sewage discharge pipe 3 is communicated with the bottom of the outer wall of the expanding section 12 and is positioned between the guide plate 2 and the outlet section 13.
When the blowout prevention separation tank provided by the embodiment of the disclosure is used for emptying natural gas, the blowout prevention separation tank is horizontally placed, namely, the axis of the tank body 1 is parallel to the horizontal plane. The inlet section 11 and the outlet section 13 are respectively communicated with a pipeline of the emptying system, so that natural gas can enter the blowout prevention separation tank from the inlet section 11 and be output from the blowout prevention separation tank from the outlet section 13. After the natural gas enters the expanding section 12 from the inlet section 11, the flowing speed of the natural gas is reduced because the inner diameter of the expanding section 12 is larger than that of the inlet section 11 and the outlet section 13. In the flowing process of the natural gas, the partial effusion and the powder mixed in the natural gas fall to the bottom of the inner wall of the diameter expanding section 12 under the action of gravity because of the larger weight of the natural gas. After flowing through the first flow-through gap a, is discharged through the drain pipe 3. And the other part of accumulated liquid and dust flow to the guide plate 2 along with the natural gas and flow towards the bottom of the inner wall of the diameter expanding section 12 along the guide hole 21, so that the accumulated liquid and dust can be merged with the deposited accumulated liquid and dust and are discharged through the drain pipe 3. The remaining pure natural gas flows out of the blowout prevention separation tank through the outlet section 13 so as to realize the separation of the natural gas from the accumulated liquid and the powder.
That is to say, dispose the knockout drum of preventing spouting that this disclosed embodiment provided on emptying system's pipeline, can effectually separate natural gas and hydrops and powder to make pure natural gas flow out alone, avoided hydrops and powder to flow out along with the natural gas together, and the polluted environment.
Since the inner diameter of the expanding section 12 is larger than the inner diameters of the entrance section 11 and the exit section 13, it is not easy to directly connect the expanding section 12 to the entrance section 11 and the exit section 13, respectively. In order to solve this problem, in the present embodiment, the tank 1 further includes two reducing sections 14, one of the two reducing sections 14 is communicated between the inlet section 11 and the expanding section 12, and the other of the two reducing sections 14 is communicated between the outlet section 13 and the expanding section 12.

Therefore, the diameter-expanding section 12 can be conveniently communicated with the inlet section 11 and the outlet section 13 through the reducing section 14 as a transition, and the assembly difficulty is reduced.
Illustratively, the expanding section 12, the inlet section 11, the outlet section 13 and the reducing section 14 are welded together, thereby ensuring the structural strength of the tank body 1.

By the design, the natural gas can be fully decelerated after entering the diameter expanding section 12, so that the deposition time of accumulated water and powder is ensured, and the separation effect of the blowout prevention separation tank is improved.
In the above-described implementation, the flow area refers to the area through which the medium can flow. The flow area of the expanding section 12 refers to the cross-sectional area of the expanding section 12 in the vertical direction. The flow area of the inlet section 11 and the outlet section 13 refers to the cross-sectional area of the inlet section 11 and the outlet section 13 in the vertical direction.
Optionally, flange plates are disposed on both the end of the inlet section 11 far from the diameter-expanding section 12 and the end of the outlet section 13 far from the diameter-expanding section 12, and the flange plates are used to connect the inlet section 11 and the outlet section 13 with the corresponding pipes of the emptying system.
In order to ensure the flow guiding effect of the guiding holes 21, in the present embodiment, the total flow area of the guiding holes 21 is not smaller than the flow area of the inlet section 11, and the total flow area of the guiding holes 21 is not smaller than the flow area of the outlet section 13.

The flow area of the inlet section 11 refers to the cross-sectional area of the inlet section 11 in the vertical direction, and the flow area of the outlet section 13 refers to the cross-sectional area of the outlet section 13 in the vertical direction. So design can be so that the natural gas of guide plate 2 of flowing through can not be subject to the area of overflowing of water conservancy diversion hole 21 for the effect of water conservancy diversion can be purely played in water conservancy diversion hole 21, and can not exert an influence to the normal circulation of natural gas.

In the above implementation, the natural gas is blocked by the buffer plate 4 after entering from the inlet section 11, so that the flow velocity is reduced, and then flows out from the second flow-through gap B. That is, the buffer plate 4 is used for decelerating the natural gas entering from the inlet section 11 to improve the flowing time of the natural gas in the expanding section 12, so that the accumulated liquid and powder in the natural gas can be sufficiently deposited, thereby improving the separation effect of the blowout prevention separation tank.
Exemplarily, in order to ensure the buffering effect of the buffering plate 4 on the natural gas, the axis of the inlet section 11 coincides with the buffering plate 4, and the buffering plate 4 faces the inlet section 11. By the design, the natural gas can be fully decelerated by the buffer plate 4 after entering from the inlet section 11, so that the flowing time of the natural gas in the diameter expanding section 12 is prolonged.
Illustratively, the dimension of the second flow-passing gap B in the vertical direction is larger than the dimension of the first flow-passing gap A in the vertical direction.
Because the natural gas only has the second flow-through gap B when flowing through the buffer plate 4, the second flow-through gap B needs to be designed to be larger, thereby avoiding the influence of the excessive buffer plate 4 on the normal flow of the natural gas.
Optionally, the buffer plate 4 is perpendicular to the axis of the expanded diameter section 12. So design, can make the area of facing the wind of buffer board 4 bigger, buffer board 4 is bigger to the area of contact of natural gas promptly to the effect of better buffering that plays.

In order to avoid the effusion and the powder from flowing out of the outlet section 13, in the embodiment, the blowout prevention separation tank further comprises a water baffle 5, the water baffle 5 is positioned in the tank body 1, and the water baffle 5 is connected with the bottom of the inner wall of the outlet section 13 and inclines towards the bottom of the inner wall of the expanding section 12 in the direction from the outlet section 13 to the inlet section 11.
In this embodiment, ponding and powder can be stopped by breakwater 5 after flowing to outlet section 13, can not further cross breakwater 5 to from outlet section 13 outflow jar body 1, avoided ponding and powder to cause the pollution to the environment.
Illustratively, the included angle alpha between the water baffle 5 and the axis of the expanding diameter section 12 is 15-30 degrees. So design, can guarantee effectively that breakwater 5 blocks ponding and powder promptly, can guarantee again that the natural gas is smooth and easy flows out jar body 1 by export section 13.
In this embodiment, the drain pipe 3 is provided with a drain valve 31, and the drain pipe 3 can be opened or closed through the drain valve 31.
In addition, the blow off pipe 3 deviates from the one end of jar body 1, respectively with gas field pond and gas field water flash tank intercommunication. That is, the accumulated water and powder in the sewage drain 3 can flow to the gas field pool at a low position under the action of gravity. It can also flow to a high-lying gas field water flash tank under the thrust of the flare system.
