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

Embodiment

[0018] The tongue-type damping valve tray of this embodiment, such as Figure 1 to Figure 4 As shown, it includes tray 1 and float valve 2 that can move up and down. The tray 1 is provided with mounting holes for the installation of the float valve. The float valve 2 includes a rectangular valve cover 3 above the tray 1 and valve legs 4 extending downward from the opposite side edges of the valve cover to the bottom of the tray.

[0019] The valve cover 3 is provided with at least two upwardly arched tongue holes 5, and the other side edges of the valve cover 3 are provided with downwardly folded serrated edges 6. The serrated edges 6 of the valve cover are used when the float valve 2 falls. Abutting the upper surface of the tray 1 .

[0020] A ring of protrusions 7 is fixed on the bottom surface of the valve cover 3 , and the tongue hole 5 is located in the ring of protrusions 7 of the valve cover 3 . The ring protrusion 7 may be a ring of concave protrusions formed by punc...

Abstract

The invention relates to a tongue-shaped damping float valve tray and belongs to the technical field of general physical separation devices. The tongue-shaped damping float valve tray comprises a tray and float valves capable of moving up and down, wherein mounting holes for mounting of the float valves are formed in the tray; each float valve comprises a rectangular bonnet arranged on the tray and valve legs extending downwards from the edges of two opposite sides of the bonnet to be below the tray; at least two upwardly arched tongue holes are formed in each bonnet; downwardly folded saw-toothed edges are arranged on the edges of other two sides of each bonnet; the saw-toothed edges of the bonnets are used for propping against the upper surface of the tray when the float valves fall down; a circle of bulge is fixed on the bottom of each bonnet; the tongue holes are located in the bulge of the corresponding bonnet; an interlayer cavity is formed in each bonnet and filled with damping rubber. The tongue-shaped damping float valve tray has the advantages that airflow is dense and uniform in dispersion and full gas-liquid contact is realized.

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] Float 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 of the tower equipment in the valve tower and the height of the technical level directly affect the output, quality, recovery rate, economic benefits and other aspects of the product. [0003] The valve tower features a floating valve that can move up and down at each mounting hole. When the air velocity of the installation hole is high, the float valve is lifted up, and when the air velocity is low, the float valve is lowered due to its own weight. The lifting position of the float valve is automatically adjusted with the air flow, so that the air velocity entering the l...
