Description
Technical Field
The invention relates to the technical field of chemical equipment, in particular to a strip-shaped float valve tower tray for preventing float valves from being bonded.
Background
The tower plates are divided into bubble cover type, sieve hole type, floating valve type, inclined hole type and other special type according to the bubbling element. The floating valve tray is provided with an open valve hole on the tray and is provided with a valve element (except a fixed valve) capable of floating up and down. The gas flow area of the float valve tower plate can be automatically adjusted along with the change of the gas load, so that the stable operation can be kept under a wider gas load; meanwhile, the gas is blown out in the horizontal direction, the gas-liquid contact time is long, entrainment is less, the operation elasticity is good, the tower plate efficiency is high, and the method is widely applied to the industry.
Nutter developed a Nutter float valve in 1951, which was subsequently improved to appear as a P-shaped, D-shaped, L-shaped, DL-shaped, etc. float valve. The strip-shaped floating valve is characterized in that the strip-shaped floating valve cannot rotate, so that the strip-shaped floating valve is not easy to wear, and the valve plate cannot be clamped and fall off; because the gas of the strip-shaped floating valve is sprayed out from two sides, unlike the spraying of a round floating valve from the periphery, the liquid back mixing on the tower plate is less than that of the round floating valve tower plate, and the efficiency is relatively high; it is possible to discharge a larger opening ratio than the circular hole shape, thereby improving the processing ability. The industrial practice proves that the operating performance of the strip-shaped structure floating valve tower plate is slightly superior to that of the traditional circular floating valve tower plate.
However, the existing strip-shaped float valve tray and strip-shaped float valve have the big problems that the valve plate can only be made of stainless steel, the float valve is easy to clamp, rust or adhere in operation and cannot be freely opened, the rust float valve must be replaced when the tray is overhauled, and the efficiency of the tray is seriously influenced.
