Disk-shaped damping floating valve tray

Abstract

The invention relates to a disk-shaped damping floating valve tray which comprises a tower plate and a floating valve capable of moving up and down, wherein a mounting hole for mounting the floating valve is formed in the tower plate; the floating valve comprises a circular valve cover arranged above the tower plate and valve legs extending downwards from the circumferential edge of the valve cover to the lower side of the tower plate; the valve legs are distributed at intervals along the circumferential edge of the valve cover; at least two upwards arched first tongue holes are formed in the valve cover; a downwards folded sawtooth edge is arranged at the circumferential edge of the valve cover; the sawtooth edge of the valve cover is pressed against the upper surface of the tower plate when the floating valve falls off; a plurality of second tongue holes are formed in the tower plate; a circle of bulge is fixed on the bottom surface of the valve cover; the first tongue holes are positioned in the bulge of the valve cover; the valve cover is filled with damping rubber. The disk-shaped damping floating valve tray has the advantages of dense and uniform air flow dispersion and full air-liquid contact.

Description

technical field [0001] The invention relates to a tray, which belongs to the technical field of general physical separation operation devices. Background technique [0002] Circular valve tower (also known as disc-shaped valve tower) is a new type of tower with simple structure, low manufacturing cost, and can adapt to common material conditions. It is one of the most widely used tower types in the chemical and oil refining industries. one. The performance and technical level of the tower equipment in the valve tower directly affect the output, quality, recovery rate, economic benefits and other aspects of the product. [0003] The circular float valve tower is characterized by installing a float valve that can move up and down at each mounting hole. When the gas velocity in the installation hole is high, the float valve is lifted up, and when the air velocity is low, the float valve will drop due to its own weight. The lifting position of the float valve is automatically...

AI Technical Summary

Problems solved by technology

[0004] Although the trays of circular floating towers have the advantages of high mass transfer efficiency and high operating flexibility, the applicant found that in industrial production, they still have the following disadvantages: 1) Due to the irregular rise of the air flow, the float valve has a large impact on the air flow. The treatment is not ideal, the gas flow is unevenly dispersed and the gas-liquid contact is insufficient; 2) Because the float valve cannot be installed on the edge of the tray, it is easy to generate a mass transfer dead zone, so that the gas-liquid contact in this area is not sufficient
