Liquid guide tower plate with horizontal opening hole

Abstract

The invention discloses a liquid guide tower plate with a horizontal hole. The liquid guide tower plate comprises a tower shell and further comprises a down-flow plate, a bottom plate, a liquid guideplate weir, a liquid guide plate, a liquid stopping plate connecting plate and a liquid stopping plate, wherein the bottom plate is fixedly mounted on an inner wall of the tower shell and a plate holeis formed in the bottom plate; the down-flow plate is fixed on the inner wall of the tower shell; a downcomer is enclosed by the down-flow plate and the tower shell; the liquid guide plate is seamlessly connected with the down-flow plate; a gap is formed between the liquid guide plate and the bottom plate; a slope is formed between the liquid guide plate and the bottom plate; a liquid guide platehole is formed in a position, corresponding to the plate hole, on the liquid guide plate; the liquid guide plate weir is fixed on the upper surface of the liquid guide plate and surrounds the periphery of the liquid guide plate hole; two ends of the liquid stopping plate are connected with the bottom plate through the liquid stopping plate connecting plate; the slope is formed between the liquidstopping plate and the bottom plate. According to the tower plate disclosed by the invention, a gas-liquid contact plate hole structure is simple and a gas and liquid passing capability is great; theliquid guide tower plate is especially suitable for working conditions with a large liquid-gas ratio; furthermore, a gas-liquid channel of the tower plate is large and the tower plate has an anti-blocking capability.

Description

technical field [0001] The invention relates to mass transfer and separation equipment used in the petrochemical industry, in particular to a liquid-conducting horizontal open-hole tray. Background technique [0002] Tray is a mass transfer separation equipment used in the process of rectification, absorption and desorption in the petrochemical industry. Among them, the new vertical sieve tray is equipped with a cover at the corresponding position of the hole on the plate, and the liquid phase on the plate is separated from the cover. The gap at the bottom flows into the cover body, is blown up by the gas phase entering from the bottom of the opening on the tray plate, and is lifted into the cover body, where it fully contacts in the cover body to complete mass transfer. Due to its large processing capacity, good mass transfer effect and low pressure reduction, it has been widely used in industry. However, under the condition of large liquid-gas ratio, the volume of the gas...

Problems solved by technology

[0005] Compared with the prior art, the beneficial effect of the present invention is that the present invention is used to solve the problem of low mass transfer efficiency of the existing new vertical sieve tray under the condition of large liquid-gas ratio, and the gas phase carries the liquid phase from the upper surface of the bottom plate The height to the upper surface of the liquid guide plate is small, so that the pressure drop of the tray is small; the plate hole structure of the gas-liquid contact is simple, and the gas-liquid passing capacity is large, especially suitable for the working condition of a large liquid-gas ratio. In addition, the gas-liquid passage of the tray Large, the tray has anti-clogging ability
