Spacing area sum between per two hexagon float valves is greater than the side direction breathing area of twice.
Said flanging extends into to both sides respectively in foot bottom portion and can make the hexagon float valve still can not break away from two parts of column plate upper and lower the floating of column plate.
Said regular hexagon end face, leg and flanging are through the punch process manufacturing, become a globality member.
A kind of method of using the exchange of said hexagon float valve control column plate gas-liquid; It is characterized in that the hexagon float valve is arranged in cellular on column plate, the leg of a corresponding adjacent float valve of side direction passage; Guaranteed the monoblock column plate gas-liquid exchange evenly, no dead angle.
Wherein have the leg of leg holes; Be arranged in downstream along the flow direction; The airflow direction of two side direction passages that it is adjacent becomes 60 ° of angles with the flow direction, promote liquid and flow to the downflow weir direction, and the air-flow of leg holes then stops; The air-flow of a side direction passage of adjacent float valve flows to the opposite direction of flow to guarantee liquid that can not.Guaranteed that liquid to the motive force that the downflow weir direction flows, has reduced the liquid level drop of tower tray, distribution of gas is more even, has improved the efficient of the mass-and heat-transfer of tower tray.
The invention has the beneficial effects as follows: hexagon float valve of the present invention, the maximum percent opening of tower body can reach 20%, after float valve is opened; Having three strands of air-flows to promote flow along liquid flow direction advances; The power that flow is advanced strengthens, and liquid level is more steady, and distribution of gas is more even; Improve the efficient of column plate, can improve plate efficiency 20%; Increased the percent opening of plate column column plate unit are greatly; Improved the disposal ability of plate column; And the method for the control column plate vapour-liquid that proposes to said hexagon float valve ad hoc structure exchange; Then can make the vapour-liquid exchange of monoblock column plate evenly not have the dead angle, improve the mass-and heat-transfer efficient of tower tray.
