Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, and in particular to an anti-clogging distillation column tray. Background Technology

[0002] In existing technologies, plate distillation columns include a column body, on which are installed a material inlet pipe in the middle of the column, a reboiler gas phase inlet pipe at the bottom of the column, a liquid phase outlet pipe at the bottom of the column, and a stationary gas phase outlet pipe. Trays are installed inside the column body. The liquid phase moves from top to bottom and is dispersed on the trays, while the gas phase moves from bottom to top, passes through the trays, and undergoes gas-liquid mass and heat transfer, thereby realizing the distillation operation and ultimately achieving the purpose of separating components with different volatility in the material.

[0003] However, in actual production, there are often a small amount of mechanical impurities in the materials. After these impurities enter the column, they tend to accumulate in the trays of the distillation column, affecting the full contact between the liquid and gas phases, and even clogging the trays. This requires frequent cleaning of the trays, making it inconvenient to use. Utility Model Content

[0004] In order to overcome the shortcomings of existing technology where the trays are frequently clogged, one of the objectives of this utility model is to provide an anti-clogging distillation column tray.

[0005] One of the objectives of this utility model is achieved by the following technical solution: a clogging-proof distillation column tray, comprising a tray block: an overflow weir one is fixedly connected to the upper side of the left part of the tray block, an overflow weir two is fixedly connected to the upper side of the right part of the tray block, a downcomer is fixedly connected to the lower side of the right part of the tray block, and a cleaning structure is provided between the overflow weir one and the overflow weir two;

[0006] The cleaning structure includes a rotating shaft rotatably connected to the upper side of the tray block. A drive rod is fixedly connected to the outer side of the rotating shaft, and a cleaning brush is provided on the lower side of the drive rod. This helps reduce tray clogging and the frequency of manual cleaning.

[0007] According to the aforementioned anti-clogging distillation column tray, the cleaning brush and the tray block are slidably connected. This facilitates the cleaning of impurities from the tray by the cleaning brush.

[0008] According to the aforementioned anti-clogging distillation column tray, a bracket is fixedly connected to the front side of the cleaning brush, and the bracket is fixedly connected to the drive rod by screws. This facilitates the fixation of the cleaning brush.

[0009] A clog-resistant distillation column tray is provided, wherein two L-shaped holders are provided, and the holders and drive rods are slidably connected. This facilitates the fixing of the cleaning brush.

[0010] The above solution has the following advantages: by setting up the cleaning structure, the cleaning brush can clean the impurities on the tray, greatly reducing tray blockage and the frequency of manual cleaning, and making it convenient to use.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-2A clog-resistant distillation column tray includes a tray block 1. An overflow weir 2 is fixedly connected to the upper left side of the tray block 1, and an overflow weir 3 is fixedly connected to the upper right side of the tray block 1. A downcomer 4 is fixedly connected to the lower right side of the tray block 1. A cleaning structure 5 is provided between the overflow weir 2 and the overflow weir 3. The cleaning structure 5 includes a rotating shaft 501, which is rotatably connected to the upper side of the tray block 1. A drive rod 502 is fixedly connected to the outer side of the rotating shaft 501. A cleaning brush 503 is provided below the drive rod 502. The cleaning brush 503 is slidably connected to the tray block 1. A bracket 504 is fixedly connected to the front side of the cleaning brush 503, and the bracket 504 is secured by screws. The cleaning structure 5 is fixedly connected to the drive rod 502. Two L-shaped card holders 504 are provided, and the card holders 504 and the drive rod 502 are slidably connected.
