Description

Technical Field

[0001] The utility model relates to the technical field of vertical float valve tower trays, in particular to a high-efficiency vertical float valve tower tray. Background Art

[0002] The tray is one of the main components of the plate tower. It is a component that realizes heat and mass transfer. It can make two fluids exchange heat and mass closely between the two phases to achieve the purpose of separating the components of liquid mixture or gas mixture. The tray is composed of tray, downcomer and overflow weir, fasteners and supports. There are two types of trays: whole block type and segmented type. Generally, when the tower diameter is 300-800mm, the whole block type is adopted; when the tower diameter is greater than 800mm, the segmented type can be adopted. The segmented tray plates are mostly self-beam type or trough type. Using the self-beam type, the spacing between the support plates at both ends of the tower plate is allowed to deviate by 3mm. When installing the tower plate, first temporarily fix it. After the size and gap of each part are adjusted to meet the requirements, fix it with clips and bolts. Each time a layer of tower plate is assembled, it is necessary to calibrate the level with a spirit level. After the level is qualified, remove the channel plate and place it on the tower plate. After the internal parts are installed, clean the inside of the equipment. Do not leave tools in the equipment to ensure that there is no rust, mud, scraps, welding rods and other debris inside the equipment to prevent affecting subsequent mass transfer.

[0003] The Chinese patent with announcement number CN219783841U discloses an efficient vertical float valve tray, which relates to the technical field of float valve tray, including a tray body, a rectangular array on the top of the tray body with a valve body, fixing bolts are threadedly connected on both sides of the top of the valve body, the bottom end of the fixing bolt is threadedly connected to the tray body, and a joint is welded on the top of the valve body. The valve body is easy to install and disassemble. The main steps are to simultaneously pass the fixing bolts on both sides through the valve body and the tray body, and then tighten them. When the gas and liquid pass through the valve body, they will directly enter the joint. The joint and the valve body are integrated. After the gas and liquid enter the joint, they will push the sleeve cap through the top head to expose the ring mouth, thereby solving the problem that bubbles may form when the gas and liquid come out of the outlet of the float valve. If the bubbles are not broken, it will affect the subsequent gas and liquid overflowing from the outlet. The inner patch will scrape the position of the ring mouth through a scraper during the lifting process. The scraper will puncture the bubbles that may be generated when scraping the ring mouth, and at the same time scrape away the sticky substances.

[0004] The above-mentioned existing technical solutions have the following defects: the valve body is fixed to the disk body by two sets of fixing bolts. Therefore, when disassembling and assembling the valve body, the two sets of fixing bolts need to be disassembled and assembled first before the valve body can be disassembled and assembled, thereby reducing the disassembly and assembly efficiency of the valve body, and the two sets of fixing bolts are difficult to fix the valve body on the disk body more comprehensively, thereby reducing the reliability of the device. In response to the above situation, technical innovation is carried out on the basis of the existing high-efficiency vertical floating valve tower plate. Utility Model Content
