Description

Technical Field

[0001] The utility model relates to the technical field of tower trays, in particular to a chemical tower tray with adjustable gas-liquid ratio. Background Art

[0002] A tower tray is the primary component in a plate tower that provides a space for gas-liquid mass and heat transfer. It allows for close heat and mass exchange between two fluid phases to separate the components of a liquid or gas mixture. It primarily consists of a gas-liquid contact element (such as a float valve, bubble cap, or sieve hole), a liquid receiving tray, an overflow weir, downcomers (or downcomers), tray supports, and fasteners. When the tower diameter is small, each tray is a single piece, known as a monolithic tray. As one of the primary components of a plate tower, the tray facilitates heat and mass transfer. The tray consists of the tray, downcomers, overflow weirs, fasteners, and supports.

[0003] The existing chemical tower trays are not convenient for automatically adjusting the gas-liquid ratio. Due to the different changes in gas pressure, it is not convenient to change the tower tray with the changes in gas phase, which leads to insufficient gas-liquid flow. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a chemical tower tray with adjustable gas-liquid ratio.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a chemical tower plate with adjustable gas-liquid ratio, comprising a tower plate body, a valve hole is provided on the surface of the tower plate body, a valve cover is provided on the surface of the valve hole, a valve leg is provided at the bottom of the valve cover, an air hole is provided on the surface of the valve leg, a support frame is provided inside the valve hole, a fixing cylinder is provided at the end of the support frame, an air bag is provided inside the fixing cylinder, a connecting plate is provided at the end of the air bag, a support frame is provided on the side of the connecting plate, and a sliding groove is provided on the surface of the fixing cylinder.

[0006] Preferably, a liquid receiving trough is provided on the surface of the tray body, and a liquid downcomer is provided on the surface of the tray body.

[0007] Preferably, an overflow weir is provided on the surface of the tray body, and the overflow weir is adapted to the downcomer.

[0008] Preferably, a limit block is provided on the surface of the valve leg, and three limit blocks are arranged in a circular array.

[0009] Preferably, a plurality of valve holes are arranged linearly and equidistantly, and the shape of the valve hole is adapted to the shape of the valve leg.

[0010] Preferably, the support frame is slidably connected to the sliding groove, and the support frame is adapted to the sliding groove.

[0011] Preferably, the end of the support frame is fixedly connected to the interior of the valve cover, and a plurality of air holes are provided in a linear array.

[0012] Beneficial effects

[0013] In the utility model, a fixed cylinder, a support frame, an airbag, a connecting plate and a sliding groove are adopted. When the pressure and flow of the gas phase are large, the airbag becomes inflated, and the expansion of the airbag is used to squeeze the connecting plate, thereby driving the support frame to slide upward in the sliding groove, causing the valve cover and the valve leg to move upward, so that the gas phase flows upward from the gap between the air hole and the valve leg, and slowly mixes with the liquid phase. When the air pressure is low, the airbag contracts, driving the valve cover and the valve leg to slide downward, which is convenient for automatically adjusting the gas-liquid ratio and ensuring sufficient gas-liquid flow.
