Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Example 1
The present embodiment provides a gas-liquid separation apparatus, as shown in fig. 1, including a separator body 1, a gas-liquid inlet 2, a gas delivery pipe 3, and a liquid delivery pipe 4.
Wherein, separator main part 1 has vertical extension and is closed separation chamber 11, and the top of for example separator main part 1 is the circular arc blind end, and its bottom is straight end, is equipped with drain 12 on the bottom of separator main part 1 to sealed being equipped with the sealed lid of detachably on drain 12, being convenient for carry out regular clearance to the separation intracavity. Alternatively, the separation chamber 11 is generally cylindrical.
The gas-liquid inlet 2 is arranged on the side wall of the separator main body 1, is communicated with the separation cavity 11 and is used for inputting gas-liquid mixed fluid into the separation cavity 11. For example, the side wall of the separator body 1 is provided with a mounting hole, the gas-liquid delivery pipe 21 is hermetically penetrated in the mounting hole, one end of the gas-liquid delivery pipe 21, which is positioned outside the separator body 1, serves as a gas-liquid inlet 2, and the other end, which extends into the separation cavity 11, serves as a gas-liquid outlet. The gas-liquid conveying pipe 21 conveys external gas-liquid mixed fluid into the separation cavity 11, the gas-liquid mixed fluid flows upwards in the separation cavity 11 because the density of the gas is smaller than that of the liquid, the liquid sinks at the lower part of the separation cavity 11 under the gravity to realize gas-liquid separation, and the separation cavity 11 is divided into a liquid chamber and a gas chamber from bottom to top by taking the liquid level of the gas-liquid separation as a boundary.
Since the gas-liquid content at the gas-liquid inlet 2 changes, or the gas outlet pressure at the gas outlet 32 and the pressure at the liquid outlet 42 change, the liquid level of the gas-liquid separation floats up and down, and thus the liquid level of the gas-liquid separation is a relatively dynamic liquid level.
As shown in fig. 1, the gas outlet pipe 3 is hermetically arranged on the side wall of the separator body 1, the part of the gas outlet pipe extending into the separation cavity 11 is vertically extended and the top of the part is used as a gas inlet 31, and the gas inlet 31 is communicated with the gas chamber; the gas inlet is arranged close to the inner wall surface of the top of the separator body 1, the other end of the gas delivery pipe, which is positioned outside the separator body 1, is used as a gas outlet 32, the gas outlet 32 is positioned below the gas inlet 31, and the gas delivery pipe and the gas-liquid delivery pipe 21 are arranged in a staggered manner in the separation cavity 11. Optimally, the gas outlet 32 is located below the gas-liquid inlet 2.
As shown in fig. 1, the liquid outlet pipe 4 is sealingly inserted through the sidewall of the separator body 1, but avoids the gas-liquid conveying pipe 21 and the gas outlet pipe 3, the liquid outlet pipe 4 extends into the separation chamber 11 and partially extends vertically, the bottom of the part is used as a liquid inlet 41, the liquid inlet 41 is arranged close to the inner wall surface of the bottom of the separator body 1, the other end outside the separator body 1 is used as a liquid outlet 42, and the liquid outlet 42 is higher than the liquid inlet 41.
A first gap and a second gap are reserved between the gas inlet 31 and the liquid inlet 41 and the top and the bottom of the separator main body 1 respectively, the gas in the gas chamber can conveniently enter the gas delivery pipe 3 due to the arrangement of the first gap, and the solution in the liquid chamber can conveniently enter the liquid delivery pipe 4 due to the arrangement of the second gap.
Meanwhile, the height difference h between the air inlet 31 and the liquid inlet 41 satisfies:
Wherein P1 is the pressure at the gas outlet 32, and P2 is the pressure at the liquid outlet 42. The applicant finds that the liquid level height of the gas-liquid separation can be automatically adjusted as long as the height difference h between the liquid inlet and the gas inlet is set to be high enough, and the liquid level height is always between the gas inlet and the liquid inlet, and the specific principle is as follows:
as shown in fig. 2, when the pressure P2 of the liquid outlet 42 is a reference level, the initial position of the liquid level of the gas-liquid separation is a0Pressure P1 at outlet 320And P20And P10When the difference reaches a limit value, the liquid level of the gas-liquid separation rises from the position A to a limit position B, the limit position B is lower than the gas inlet 31, and the pressure P2 of the liquid outlet 42 is at the moment0Pressure P1 associated with outlet port 320The following relationships exist:
P20＝P10+ ρ gX1, then X1 ═ P20－P10) V. (ρ g), where ρ is the density of the liquid in the liquid chamber in the separation chamber, i.e., when the liquid level reaches the limit position B, the distance X1 from the liquid level to the liquid outlet 42 is (P2)0－P10) When the distance h1 between the gas inlet 31 and the liquid outlet 42 is greater than X1,/(ρ g), it is ensured that even if the difference between the pressure of the liquid outlet 42 and the pressure of the gas outlet reaches a limit value, the liquid level of the gas-liquid separation reaches only the limit position B and does not reach the gas inlet 31, thereby avoiding the occurrence of the phenomenon that the separation chamber 11 is completely filled with liquid and the liquid enters the gas delivery pipe 3 through the gas inlet 31 and is discharged.
Conversely, when the pressure P1 of the air outlet 32 is higher1Pressure at outlet port P21And P11And P21The difference reaches a limit value, the liquid level of the gas-liquid separation is lowered from the position A to a limit position C, the limit position C is higher than the liquid inlet 41, the distance between the limit position C and the liquid outlet 42 is X2, and the pressure P2 of the liquid outlet 42 is at the moment1Pressure P1 associated with outlet port 321The following relationships exist:
P11＝P21+ ρ gX2, then X2 ═ P11－P21) And/(ρ g), where ρ is the density of the liquid in the liquid chamber within the separation chamber. That is, when the liquid level reaches the limit position C, the distance X2 between the liquid level and the liquid outlet 42 is (P1)1－P21) When the distance h2 between the liquid inlet 41 and the liquid outlet 42 is greater than X2,/(ρ g), it can be ensured that even if the difference between the pressure of the gas outlet 32 and the pressure of the liquid outlet reaches a limit value, the liquid level of the gas-liquid separation will only reach a limit position C, and will not reach the liquid inlet 41, and the limit position C is always higher than the liquid inlet 41, so as to avoid the phenomenon that the separation chamber 11 is fully filled with gas, and the gas enters the liquid outlet 4 through the liquid inlet 41 and is discharged.
From the above analysis, it can be seen that the height difference h between the gas inlet 31 and the liquid inlet 41 is h1+ h2, and h1 > X1 and h2 > X2 are inevitably h > (X1+ X2), so long as the height difference h between the gas inlet 31 and the liquid inlet 41 satisfies:
during the process, the gas-liquid separation liquid level can be ensured to be always between the liquid inlet 41 and the gas inlet 31 without arranging valves on the gas delivery pipe 3 and the liquid delivery pipe 4, the separation effect of the separator is ensured, the automatic adjustment of the gas-liquid separation liquid level without a control structure can be realized, the flow of the gas delivery pipe 3 or the liquid delivery pipe 4 is automatically adjusted only by the height of the separator, and then the position of the gas-liquid separation liquid level is adjusted.
In the actual use process, according to different working condition conditions, the P2 under each working condition is obtained through multiple tests0、P10、P11、P21Then, the value of h can be obtained. That is to say, the variation range of the gas-liquid separation liquid level of the separator depends on the variation range of the pressure of the gas outlet of the gas delivery pipe and the pressure of the liquid outlet of the liquid delivery pipe, or the variation range of the gas output and the liquid output, because the separator has enough height difference h, when the pressure of the gas outlet and the pressure of the liquid outlet are changed or the gas output and the liquid output are changed, the variation range of the liquid level in the separator is always between the liquid inlet of the liquid delivery pipe and the gas inlet of the gas delivery pipe, and the separated gas and liquid are ensured to enter the gas collection system and the liquid collection system through the gas inlet and the liquid inlet respectively, so that the gas-liquid separation and the transportation of the separator can stably run under the condition of no control.
As shown in fig. 1, the separator further comprises a support 6, the bottom of the separator body 1 is mounted on the support 6, for example, the support comprises four supports arranged along the circumferential direction, the tops of all the supports are fixed together, and the lower portions of all the supports are fixed together, so that the separator body 1 is overhead above the ground, the sewage draining outlet 12 is lifted, and when the separation cavity 11 of the separator body 1 needs to be cleaned, the sealing cover is convenient to detach or mount.
In the gas-liquid separation device of this embodiment, the height difference h between the gas inlet 31 and the liquid inlet 41 is specifically set, so that after gas-liquid mixed fluid enters the separation chamber 11 through the gas-liquid inlet 2, after gas and liquid are separated, gas flows upward and enters the gas delivery pipe 3 through the gas inlet 31, liquid flows downward and enters the liquid delivery pipe 4 through the liquid inlet 41, the maximum difference between the pressure of the gas outlet 32 and the pressure of the liquid outlet 42 falls into the adjustment range of the height of the separator body 1, the liquid level of gas-liquid separation can be automatically adjusted to be always between the gas inlet 31 and the liquid inlet 41, artificial control is not required, and the height of the liquid level of gas-liquid separation is not required to be adjusted by setting a valve, so that gas-liquid separation can be stably operated.
That is, when the pressure at the gas outlet increases or the gas output from the gas outlet increases (or the pressure at the liquid outlet decreases or the liquid output decreases), the pressure at the gas outlet 32 is higher than the pressure at the liquid outlet, and the pressure difference between the two increases, the liquid level of the gas-liquid separation in the separation chamber decreases from the original initial position a to the first position 51, but the position of the decreased liquid level is still higher than the liquid inlet 41; when the pressure of the liquid outlet 42 is increased or the water yield is increased (or the pressure of the gas outlet is reduced or the gas output of the gas outlet is reduced), the pressure of the liquid outlet is greater than the pressure of the gas outlet, and the pressure difference between the two is increased, the liquid level of gas-liquid separation in the separator can be raised to the second position 52 from the original initial position A, but the second position 52 is not higher than the gas inlet 31, due to the design of the height difference between the gas inlet 31 and the liquid inlet 41, the liquid level floating caused by the pressure difference between the gas outlet 32 and the liquid outlet 42 can be automatically adjusted, so that the liquid level of gas-liquid separation is always between the liquid inlet 41 and the gas inlet 31, passive control and adjustment are realized, artificial control is not needed, and the technological process of gas-liquid separation and conveying is greatly.
As a first alternative embodiment of example 1, the gas-liquid delivery pipe may not be provided, and the gas-liquid inlet may be provided directly on the separator main body wall.
As a second alternative embodiment of example 1, the gas delivery tube may have other shapes, such as an S-shaped tube, and the gas inlet may be provided on the sidewall of the gas delivery tube; similarly, the liquid delivery tube may have other shapes, such as an S-shaped tube, and the liquid inlet may be disposed on the sidewall of the liquid delivery tube, as long as the liquid outlet is higher than the liquid inlet and the liquid outlet is lower than the gas inlet.

in the preparation of the gas-liquid separating apparatus, the height of the separator body 1 is required to satisfy the above-mentioned conditions, and when the pressure P2 of the liquid outlet 42 does not satisfy the above-mentioned requirements in view of the fact that the height of the separator body 1 is too high to facilitate the processing or the processing difficulty increases, the processing is prevented from being performed at a height not satisfying the above-mentioned requirements3Pressure P1 greater than outlet 323And P23And P13The difference therebetween is larger than the above (P2)0－P10) At a limit value above which the pressure difference exceeds the regulation range of the liquid column in the vertical separator, at least one first valve 71 is arranged on the part of the gas outlet conduit 3 which projects outside the separation chamber 11, as shown in fig. 3. For example, the first valve is an electromagnetic valve, a ball valve, a gate valve, a stop valve, a butterfly valve, etc.
Under normal conditions, the first valve is in an open state, if the first valve is needed to assist in adjusting the liquid level height, the opening degree of the first valve 71 is reduced to reduce the gas outlet amount of the gas outlet and increase the pressure of the gas outlet to counteract the pressure difference between the pressure of a part of the liquid outlet and the pressure of the gas outlet, and the liquid level of gas-liquid separation is assisted to be adjusted to be lowered, so that P23And P13The difference therebetween falls within the above (P2)0－P10) Within the limits of the limit values of (2), and thus fall within the height of the separator body 1Within the adjustment range, the first valve is kept at the opening degree.

For example, the pressure at the outlet P12Greater than the pressure of the liquid outlet port P22And P12And P22The difference therebetween is larger than the above (P1)1－P21) At the limit value of (a), when the pressure difference exceeds the regulation range of the liquid column in the vertical separator, as shown in fig. 4, at least one second valve 72 may also be provided at the portion of the liquid outlet pipe extending out of the separation chamber 11.
For example, the second valve is an electromagnetic valve, a ball valve, a gate valve, a stop valve, a butterfly valve, etc., under normal conditions, the second valve is in an open state, if the second valve is needed to assist in adjusting the height of the liquid level, the opening degree of the second valve 72 is reduced, the resistance of the liquid flowing in the liquid guide pipe is increased, the liquid outlet amount of the liquid outlet is reduced, the pressure of the liquid outlet is increased, the pressure difference between the pressure of a part of the gas outlet and the pressure of the liquid outlet is offset, the liquid level of the gas-liquid separation is assisted to be increased upwards, and the pressure P1 of the gas outlet2Pressure P2 with outlet2The difference therebetween falls within the above (P1)1－P21) And further falls within the adjustment range of the height of the separator body 1, the second valve may be kept at the above-mentioned opening degree.
Or, the first valve and the second valve are both in an open state or can be opened at a certain opening degree when any valve does not participate in auxiliary adjustment of the liquid level height of gas-liquid separation, and if the liquid level height of the auxiliary gas-liquid separation needs to be participated in, the opening degree of the corresponding valve is only required to be reduced, so that the gas output or liquid output of the pipeline where the valve is located is reduced.
