As shown in fig. 1 to 3, the gas-liquid separation device according to the first embodiment of the present invention can be used for gas-liquid separation of the electrolysis products (sodium hypochlorite solution and hydrogen gas) of the sodium hypochlorite generator, and can rapidly discharge the hydrogen gas as a byproduct in the sodium hypochlorite solution.
The gas-liquid separation device comprises a gas-liquid separation tank 1, wherein the side wall of the gas-liquid separation tank 1 is provided with an inlet 11, the bottom of the gas-liquid separation tank 1 is provided with an outlet 12, the top of the gas-liquid separation tank 1 is provided with an exhaust port 13, the gas-liquid separation device also comprises an exhaust assembly 5, the exhaust assembly 5 comprises an exhaust hole plate 51 and a rotary adjusting plate 52, the gas-liquid separation device comprises a connecting rod 54 and a hydraulic rotating blade 53, wherein a gas exhaust hole plate 51 is fixed at the top of the gas-liquid separation tank 1 and seals the gas exhaust hole 13, the rotating adjusting plate 52 is attached to the gas exhaust hole plate 51, the top end of the connecting rod 54 is fixedly connected with the rotating adjusting plate 52, the bottom end of the connecting rod 54 is fixedly connected with the hydraulic rotating blade 53, the hydraulic rotating blade 53 is positioned in the gas-liquid separation tank 1, a gas exhaust hole 511 is formed in the gas exhaust hole plate 51, and the rotating adjusting plate 52 rotates under the driving of the hydraulic rotating blade 53 and covers or opens the gas exhaust hole 511, so that the ventilation area of the gas exhaust hole 511 is changed.
Specifically, after the sodium hypochlorite solution mixed with hydrogen enters the gas-liquid separation tank 1 from the inlet 11, the sodium hypochlorite solution flows out from the outlet 12 under the action of gravity, and the hydrogen flows upward and is discharged from the exhaust port 13. Due to the limitation of the exhaust assembly 5 and the pressure of the pipeline connected with the outlet 12 of the gas-liquid separation tank 1, a certain pressure is kept in the gas-liquid separation tank 1, so that the liquid level in the gas-liquid separation tank 1 is kept at a liquid level height. The hydraulic rotating blade 53 is positioned in the gas-liquid separation tank 1 and corresponds to the outlet 12, when sodium hypochlorite solution flows out of the outlet 12, the hydraulic rotating blade 53 is driven to automatically rotate (the hydraulic rotating blade 53 has a certain angle, and the blade is rotated by the component formed by the water flow speed), meanwhile, the hydraulic rotating blade 53 drives the rotating adjusting plate 52 to rotate, the rotating adjusting plate 52 periodically covers the exhaust holes 511 on the exhaust hole plate 51, so that the ventilation area of the exhaust holes 511 is periodically increased and reduced, and the periodic change of the ventilation area is matched with the liquid level change in the gas-liquid separation tank 1 through design, thereby achieving the purpose of automatic adjustment.
Under ideal operating conditions, the proportion of gas and liquid in the sodium hypochlorite solution mixed with hydrogen is kept stable, the sodium hypochlorite solution uniformly enters the gas-liquid separation tank 1 from the inlet 11, after gas-liquid separation, the sodium hypochlorite solution uniformly flows out from the outlet 12, the hydrogen is uniformly discharged from the exhaust port 13, the liquid level in the gas-liquid separation tank 1 is kept unchanged, and under the ideal operating conditions, the ventilation area of the exhaust hole 511 is kept at a fixed value. However, in actual conditions, the sodium hypochlorite solution does not enter the gas-liquid separation tank 1 uniformly, and the ratio of gas to liquid in the sodium hypochlorite solution is not stable, so that the gas amount in the gas-liquid separation tank 1 frequently fluctuates, the pressure in the gas-liquid separation tank 1 also frequently fluctuates, if the ventilation area of the exhaust hole 511 is still fixed at this time, the liquid level of the gas-liquid separation tank 1 fluctuates sharply along with the fluctuation of the pressure, and when the pressure in the gas-liquid separation tank 1 continuously increases or continuously decreases, the liquid level also continuously decreases or increases, thereby affecting the normal use of the gas-liquid separation tank 1.

1. under normal working conditions, gas in the gas-liquid separation tank 1 is uniformly discharged from the gas outlet 13, and the liquid level in the gas-liquid separation tank 1 fluctuates up and down within a reasonable range by a small amplitude along with the periodic change of the ventilation area of the exhaust hole 511; when the ventilation area of the exhaust hole 511 is gradually increased, the gas discharge amount is increased, the pressure in the gas-liquid separation tank 1 is gradually reduced, and the liquid level is gradually increased in a small range; when the ventilation area of the exhaust hole 511 is gradually reduced, the gas discharge amount is reduced, the pressure in the gas-liquid separation tank 1 is gradually increased, and the liquid level is gradually reduced.
2. When the gas amount in the gas-liquid separation tank 1 is continuously large in a certain period of time, the pressure in the gas-liquid separation tank 1 is large, the discharge rate of the gas is large (the discharge rate is large when the pressure is large), and the gas can be discharged quickly when the ventilation area of the exhaust hole 511 is gradually large; in the gas exhaust process, the pressure in the gas-liquid separation tank 1 is rapidly reduced, the gas exhaust rate is slowed down, the final gas exhaust rate reaches a stable state, the liquid level in the gas-liquid separation tank 1 slowly drops in the process, and the final gas exhaust rate reaches a new stable state (the design that the ventilation area of the exhaust hole 511 is unchanged is adopted, when the gas volume in the gas-liquid separation tank 1 is continuously large, the pressure in the gas-liquid separation tank 1 is increased due to the fact that the exhaust hole 511 cannot exhaust the gas, the liquid level continuously and rapidly drops, and finally the gas-liquid separation tank 1 cannot normally work).
3. In a certain period of time, when the gas amount in the gas-liquid separation tank 1 is continuously less, the pressure in the gas-liquid separation tank 1 is smaller, the discharge rate of the gas is smaller (the discharge rate is smaller as the pressure is smaller), and when the ventilation area of the exhaust hole 511 is gradually reduced, the gas can be quickly accumulated in the gas-liquid separation tank 1; in the gas gathering process, the pressure in the gas-liquid separation tank 1 increases fast, the exhaust rate of gas is accelerated, the exhaust rate of last gas reaches stable state, the liquid level in the gas-liquid separation tank 1 in this process slowly rises, reach a new stable state at last (and the design that the vent hole 511 area of ventilating is unchangeable, when gas volume in the gas-liquid separation tank 1 lasts less, because the unable adjustment of vent hole 511 size, the gas-liquid separation tank 1 can't hold out the breath, make the pressure in the gas-liquid separation tank 1 littleer and more, the liquid level lasts fast rising, make the unable normal work of gas-liquid separation tank 1 at last).
Further, as shown in fig. 3 to 5, a plurality of protrusions 521 are provided on the outer edge of the rotation adjustment plate 52, a plurality of exhaust holes 511 are provided, and the plurality of protrusions 521 cover or open the plurality of exhaust holes 511 when the rotation adjustment plate 52 rotates, so that the ventilation area of the exhaust holes 511 changes periodically.
