Description

Technical Field

[0001] This utility model relates to the field of industrial gas-liquid contact mass transfer, and in particular to a guided high-efficiency bidirectional floating valve tray. Background Technology

[0002] Tower equipment plays a vital role in industries such as oil refining, chemical engineering, pharmaceuticals, and environmental protection. Its performance and technological sophistication directly impact product yield, quality, recovery rate, and economic benefits. Therefore, researching and utilizing new tower equipment is of great significance for enhancing gas-liquid two-phase mass transfer processes and for industrial production.

[0003] In the early 1950s, the F1 circular floating valve tray was developed, and its overall performance held significant advantages for a long period. In the 1960s, structured packings, especially corrugated packings, emerged, making packed towers more widely used. Their significant advantages include high separation capacity, large throughput, and low pressure drop, making them very attractive for upgrading older towers to improve throughput and separation purity, replacing trays with new packings. However, the initial investment in new packings is substantial (especially for large-diameter, multi-side-stream towers), and their application is limited in production environments with corrosion, coking, or fouling. Therefore, renewed interest has emerged in seeking breakthroughs in plate towers to meet the increasing demands for high throughput and high efficiency in large-diameter distillation towers.

[0004] Currently, dozens of new types of trays have been developed. These can be broadly categorized into two types: fixed trays and valve trays. While existing fixed trays offer the advantage of simple structure, they suffer from limited operational flexibility, significant leakage, and low mass transfer efficiency during production. Valve trays, although offering greater operational flexibility, are prone to valve body rotation and detachment during long-term operation. Large liquid level gradients on the trays cause uneven gas distribution along the liquid flow direction, leading to excessive liquid leakage at the inlet and excessive liquid entrainment at the outlet. The arc-shaped region of the tray also exhibits severe contamination, significantly impacting tray efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a guided, high-efficiency, bidirectional floating valve tray to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a guided high-efficiency bidirectional floating valve tray, comprising a tray body, wherein multiple sets of mounting holes are provided on the tray body, and a floating valve assembly is disposed inside the multiple sets of mounting holes. The floating valve assembly includes a valve cover, valve legs, fixing blocks, and fixing covers. Multiple sets of valve covers are disposed inside the mounting holes. Multiple sets of valve legs are disposed on the bottom surface of the valve covers. Multiple sets of fixing blocks are disposed on the side walls of the valve covers. Multiple sets of fixing covers are disposed on the top surface of the tray body. The fixing covers are fixedly connected to the tray body. Multiple sets of mounting grooves are provided on the inner side walls of the fixing covers. The fixing blocks are disposed inside the mounting grooves. A flow groove is provided above the mounting grooves, and the cross-section of the flow groove is a triangular structure.

[0007] Preferably, the interior of the fixed cover is further provided with an airflow dispersion component, which includes a mounting ring and dispersion teeth. The mounting ring is configured in multiple sets and is disposed on the inner side wall of the fixed cover and above the valve cover. The dispersion teeth are configured in multiple sets and are disposed on the inner side wall of the mounting ring.

[0008] Preferably, the inner sidewall of the fixing cover is threaded, the mounting ring is threaded to the fixing cover, and the dispersing teeth are inclined downwards at an angle of 5-15 degrees.

[0009] Preferably, a sealing ring is provided inside the fixing cover, the sealing ring is located below the valve cover, and the sealing ring is in contact with the inside of the fixing cover.

[0010] Preferably, an installation assembly is provided below the tray body. The installation assembly includes an installation plate and installation bolts. The installation plate is located below the tray body, and multiple sets of installation bolts are provided. The installation plate is fixedly connected to the tray body through the installation threads, and the installation plate is designed with a hollow structure.

[0011] Preferably, a compression spring is provided above the mounting plate, and a limit groove is provided on the top surface of the mounting plate. Multiple sets of limit grooves are provided, and multiple sets of compression springs are provided. The compression springs are located inside the limit grooves, and one end of the compression springs is fixedly connected to the valve cover.

[0012] Preferably, the valve cover, valve leg, and compression spring are integrally formed, and the mounting ring and the dispersion teeth are integrally formed.

[0013] The beneficial effects of this utility model are:

[0014] 1. The floating valve assembly can be installed by setting the mounting holes. The valve legs can guide the valve cover and facilitate its installation. The fixing block can cooperate with the mounting groove to limit the valve cover and prevent it from shifting. On the other hand, the flow channel with a triangular cross-section allows the gaseous material to flow through the flow channel to the top of the tray body. This can achieve both adjustable and dispersed conveying of the gaseous material, increasing the uniformity of the mixing between the gaseous and liquid materials.

[0015] 2. The dispersing teeth can be installed by setting the installation ring. The dispersing teeth can form multiple gas phase channels, which further disperse the gas phase material flowing through the flow channel to the top of the tray body, thereby increasing the uniformity of the mixing of gas phase material and liquid phase material. At the same time, by setting the tilt angle of the dispersing teeth, the unobstructed flow of gas phase channels can be ensured, effectively preventing the gas phase channels from being blocked due to pressure or other reasons.

[0016] 3. The mounting plate can be fixed by setting mounting bolts. The mounting plate can limit and fix the valve cover and valve leg. The limit groove can limit the pressure spring. Thus, the installation and fixation of the valve cover, valve leg and pressure spring can be easily fixed, which facilitates the installation and disassembly of the float valve tray. The pressure spring can press and tighten the valve cover to prevent the valve cover from jamming and ensure the normal use of the device. Attached Figure Description
