Tongue valve tray

Abstract

The invention relates to a tongue type floating valve tower disc and belongs to the technical field of a common physical separation working device. The tongue type floating valve tower disc 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 rectangular valve cover arranged above the tower plate and valve legs which extend downward from the two opposite edges of the valve cover to the lower side of the tower plate; at least two upward arched tongue holes are formed in the valve cover; the other two side edges of the valve cover are provided with downwards-folded saw tooth edges; the saw tooth edges of the valve cover are used for being abutted against the upper surface of the tower plate when the floating valve falls down; one circle of bulge is fixed on the bottom surface of the valve cover; the tongue holes are located in the circle of the bulge of the valve cover; a cavity with a clamping space is formed in the valve cover; and the cavity is internally filled with a polystyrene foam layer. The tongue type floating valve tower disc has the advantages of fine, dense and uniform airflow dispersion and sufficient gas-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] Floating 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 chemical and oil refining industries. 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 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 adjusted with the gas flow, so that the gas velocity enter...

AI Technical Summary

Problems solved by technology

[0005] At present, although the floating valve tray has been greatly improved in terms of operating flexibility, in production, the applicant found that in industrial production, the air flow rises irregularly, resulting in unsatisfactory treatment of the air flow by the float valve and uneven dispersion of the air flow and insufficient gas-liquid contact
