Description

Sealing ring for rectifying tower tray Technical Field The utility model relates to the technical field of chemical equipment, in particular to a sealing ring for a rectifying tower tray. Background The rectifying tower is a common separating device in chemical production, is commonly used for separating liquid mixtures with different boiling points, the tray is an important component in the tower and is responsible for fractionation and exchange of different liquids, the sealing performance between the tray and the tower wall directly influences the rectifying efficiency, and the sealing ring for the rectifying tower tray is a sealing element arranged between the rectifying tower tray and the tray and is used for preventing leakage of liquid or gas between the trays and ensuring normal operation of the rectifying tower. The traditional sealing ring is mainly made of common rubber materials, is subjected to aging deformation easily under the action of high temperature and corrosive media for a long time, causes sealing failure, needs frequent shutdown and replacement, and in addition, the traditional sealing ring is single in structure, is difficult to adapt to deformation caused by thermal expansion and cold contraction of a tray, and is easy to generate leakage. Disclosure of utility model The utility model aims to solve the problems that the traditional sealing ring is made of common rubber, is easy to age and deform under the action of high temperature and corrosive medium for a long time, is difficult to adapt to the deformation of a tray caused by thermal expansion and contraction and is easy to leak. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a sealing washer for rectifying column tray, includes annular seal body, and annular seal body cover is established on the tray, annular draw-in groove has been seted up to the lower surface of tray, annular seal body from interior to exterior includes metal skeleton layer, elastic buffer layer and corrosion-resistant layer in proper order, V-arrangement recess has been seted up to the upper surface of annular seal body, the lower surface of annular seal body is equipped with protruding rib, and protruding rib and the annular draw-in groove phase-match at tray edge, and annular seal body is installed in rectifying column inner wall. As a further description of the above technical solution, the cross section of the annular sealing body is trapezoidal. As further description of the technical scheme, the metal framework layer is a stainless steel corrugated ring and has axial expansion. As further description of the technical scheme, the elastic buffer layer is a silicon rubber layer and is coated on the outer side of the metal framework layer. As a further description of the above technical solution, the corrosion-resistant layer is a polytetrafluoroethylene coating, and covers the surface of the elastic buffer layer. As further description of the technical scheme, the outer surface of the corrosion-resistant layer is provided with anti-skid lines. As a further description of the above technical solution, an anti-slip slot is formed on the outer side of the protruding rib. Compared with the prior art, the utility model has the beneficial effects that: When the annular sealing body is used, the multi-layer composite structure is adopted, the metal framework layer provides supporting and deformation recovery capability, the elastic buffer layer absorbs vibration, the service life of the corrosion-resistant layer is prolonged, the V-shaped groove deforms to enhance the sealing performance when being pressed through the trapezoid cross section design of the annular sealing body, the protruding ribs are matched with the annular clamping grooves, the annular sealing body is prevented from shifting, the annular sealing body is prevented from loosening through the arranged anti-skid lines, the annular sealing body is suitable for high-temperature and corrosive working conditions, and the service life of the annular sealing body device is prolonged.
