Floating valve distillation column
The valve column is a new type of tower developed, which is characterized by a valve plate that can be moved up and down at each screen. When the mesh gas velocity is high, the valve plate is lifted up, and when the airspeed is low, the valve plate is lowered due to its own weight. The valve lift position is automatically adjusted with the air flow rate, so that the gas velocity entering the liquid layer is substantially stabilized. Moreover, since the gas enters the liquid layer in the horizontal direction on the lower side of the valve sheet, the amount of liquid entrainment is reduced, and the gas-liquid contact time is prolonged.
Floating valve column; a valve tower for gas-liquid mass transfer.
The valve plate of the float valve can float and adjust its opening degree as the gas load changes. Therefore, the operation of the float valve tower is large, especially at low load, and normal operation can be maintained.
Due to the good gas-liquid contact state, the float valve tower has a small amount of mist entrainment (due to the gas level blowing), and the tray has high efficiency and large production capacity.
The tower has a simple structure, is inexpensive to manufacture, and can adapt to commonly used materials. It is one of the most widely used towers in the chemical and refining industries.
The bubbling contact device is developed on the basis of overcoming the defect of the bubble column when separating the stable isotope.
The valve tower has four forms: active blister, disc float valve, heavy disc float valve and strip float valve.
What is the difference between a valve tower and a sieve tower?
The sieve tray tower is also called a flow tower, and its gas and liquid pass through the holes of the sieve plate. The tray of this tower has no downflow tank and overflow weir. The mass transfer is carried out between the two trays, and its operation flexibility is relatively high. small. The sieve plate is a circular hole in the tray, the hole diameter is generally 6-24mm, the sieve plate tray with the downcomer, and the flow tray without the downcomer.
The float valve tower has a downcomer and a weir, the gas top open float valve rises in contact with the liquid on the tray, the mass transfer is carried out on the tray, and the liquid descends through the downcomer. Its operation flexibility is large. The float tray is opened on the tray, and the float valve is placed in the hole to move up and down. The float valve looks like a round, rectangular, irregular one, which has improved handling and flexibility and efficiency compared to the sieve tray. The advantages of the valve tray are that the structure is simple and anti-blocking, the pressure drop is small, and the cost is low.
Shandong Jinta Machinery Group Co., Ltd. can use different trays to make distillation towers according to different situations to ensure the normal operation of various alcohol equipment and chemical equipment.
