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

Embodiment

[0017] The disk-shaped valve tray of the present embodiment, such as Figure 1 to Figure 5 As shown, it includes a tray 1 and a float valve 2 that can move up and down. The tray 1 is formed with an installation hole for the installation of the float valve. The float valve 2 includes a circular valve cover 3 arranged above the tray 1 and a valve leg 4 extending downward from the periphery of the valve cover to the bottom of the tray. The valve legs 4 are distributed at intervals along the periphery of the valve cover 3 .

[0018] In this embodiment, the peripheral edge of the valve cover 3 is provided with a serrated edge 6 folded downward, and the serrated edge 6 of the valve cover is used to abut against the upper surface of the tray 1 when the float valve 2 falls. A number of tongue holes 10 are opened on the tray 1, and the tongue holes 10 are located between adjacent float valves 2 or on the edge of the tray 1, and the distribution density of the tongue holes 10 on the ed...

Abstract

The invention relates to a disc-shaped float valve tower disc. The tower disc comprises a tower plate and a float valve which can move up and down, wherein a mounting hole used for mounting the float valve is formed in the tower plate; the float valve comprises a round valve cover and valve legs; the round valve cover is arranged above the tower plate; the valve legs downwards extend from the periphery of the valve cover to the place below the tower plate and are distributed along the periphery of the valve cover at intervals; a sawtooth edge which is downwards turned and folded is arranged on the periphery of the valve cover and pushes against the upper surface of the tower plate when the float valve falls down; a plurality of tongue holes are formed in the tower plate; a circle of bump is fixed to the bottom surface of the valve cover; a polystyrene foam layer is arranged in the valve cover. The disc-shaped float valve tower disc has the advantages that airflow dispersion is fine, dense and uniform, and gas-liquid contact is full.

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 installation 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 automatic...
