Embodiment Construction

[0020] In view of the importance of improving the operating flexibility and separation efficiency of the rectification tower, a new method of combining guided trays, sieve trays and float valves has been developed to develop a guided sieve tray valve column with greater operating flexibility and higher separation efficiency. .

[0021] like figure 1 , 2 As shown, the basic structure of the guided sieve plate float valve tower composed of disc-shaped float valves includes a tower body 1, a tray 2, a downcomer plate 7, and a liquid receiving plate 9, and a bubbling accelerator is set at the liquid inlet of the tray 2 6. There are floating tongues 3, guide holes 4, sieve holes 5 and disc-shaped floating valves 8 on the surface of the tray 2.

[0022] like image 3 , 4 As shown, the basic structure of the guided sieve plate float valve tower composed of strip float valves includes a tower body 1, a tray 2, a downcomer plate 7, and a liquid receiving plate 9, and a bubbling pro...

Abstract

The invention relates to a guiding sieve plate float valve tower, belonging to a gas-liquid mass-transfer separation plant in chemical process. The guiding sieve plate float valve tower disclosed herein mainly comprises a tower body (1), a tower plate (2), a down-flow plate (7), a seal pan (9), etc., wherein the liquid inlet of the tower plate (2) is provided with a bubbling promoter (6), the plate surface of the tower plate is provided with a floating tongue (3), a guiding pore (4), a sieve pore (5) and a float valve. According to the invention, when the gas velocity is low, the float valve on the tower plate is not open, gas only passes through the guiding pore (4), the sieve pore (5) and the floating tongue (3); when the gas velocity increases to a certain level, the float valve is open, and the opening height of the float valve increases gradually with the increase of the gas velocity. The guiding sieve plate float valve tower disclosed herein has the advantages of simple structure, low cost, and greatly raised operation flexibility and separation efficiency.

Description

technical field [0001] The invention relates to a guide sieve plate floating valve tower, which belongs to the vapor-liquid mass transfer and separation equipment in the chemical process. Background technique [0002] As an important equipment for mass transfer and heat transfer between gas-liquid and liquid-liquid, towers are widely used in the separation of substances in oil refining, petrochemical, fine chemical, fertilizer, pesticide, pharmaceutical, environmental protection and other industries, involving steam (fine) Distillation, absorption, desorption, stripping, extraction and other chemical unit operations. As the unit equipment with the largest number of applications, the widest coverage and the largest energy consumption in chemical production, tower equipment has become one of the most active fields for reducing processing costs and improving economic benefits. The performance of tower equipment It has an important impact on the production capacity, product qua...
