For height always between air inlet and inlet, concrete principle is as follows:
As shown in Fig. 2, gas-liquid separation liquid level initial position is A using the height of liquid outlet 42 as reference data, work as liquid outlet
42 pressure P20The pressure P1 of the gas outlet > 320, and P20With P10Difference when reaching the limit values, the liquid level of gas-liquid separation by
Location A rises to extreme position B, and extreme position B is lower than air inlet 31, at this time the pressure P2 of liquid outlet 420With gas outlet 32
Pressure P10There are following relational expressions:
P20=P10+ ρ gX1, then X1=(P20- P10)/(ρ g), wherein ρ is the density of liquid in liquid chamber in disengagement chamber,
That is, liquid level to the distance between liquid outlet 42 X1 is (P2 at this time when liquid level reaches capacity position B0- P10)/(ρ g) when, when
When air inlet 31 arrives the distance between liquid outlet 42 h1 > X1, the pressure even if liquid outlet 42 and the pressure of gas outlet are ensured that
Between difference when reaching the limit values, the liquid level of gas-liquid separation can only achieve extreme position B, will not reach at air inlet 31, keep away
Exempt from disengagement chamber 11 complete hydraulically full, the phenomenon that liquid is discharged through air inlet 31 into gas eduction tube 3.
On the contrary, working as the pressure P1 of gas outlet 321The pressure P2 of > liquid outlet1, and P11With P21Difference reach capacity
The liquid level of value, at this time gas-liquid separation drops to extreme position C by location A, and extreme position C is higher than inlet 41, and extreme position C is arrived
Spacing between liquid outlet 42 is X2, at this time the pressure P2 of liquid outlet 421With the pressure P1 of gas outlet 321There are following relational expressions:
P11=P21+ ρ gX2, then X2=(P11- P21)/(ρ g), wherein ρ is the density of liquid in liquid chamber in disengagement chamber.?
That is, liquid level to the distance between liquid outlet 42 X2 is (P1 at this time when liquid level reaches capacity position C1- P21)/(ρ g) when, when
When inlet 41 arrives the distance between liquid outlet 42 h2 > X2, the pressure of the pressure and liquid outlet even if gas outlet 32 is ensured that
