Description

Technical Field

[0001] The utility model relates to the technical field of scrubbing tower trays, in particular to a scrubbing tower tray. Background Art

[0002] Early washing equipment mainly adopted a simple tray design. By setting horizontal or inclined trays in the tower, turbulence was generated when the gas contacted the liquid, thereby increasing the contact area and promoting mass transfer. These trays were usually made of metal or plastic and had a relatively simple structure. With the progress of technology, wet scrubbing towers gradually replaced the early dry equipment. The wet scrubbing tower sprays liquid in the tower to contact the gas, thereby more effectively removing pollutants in the gas. The tray still plays an important role in the wet scrubbing tower, but its design and material selection have been gradually improved. The composition structure of the scrubbing tower tray includes a tower body, trays, packing, a spraying system, gas inlets and outlets, and a washing liquid circulation system. However, during the use of the existing scrubbing tower trays, it is easy to cause unstable contact between the gas phase and the liquid on the trays, resulting in ineffective washing work. Therefore, it is necessary to solve the above technical problems. Summary of the Utility Model

An overflow weir is installed between the downcomer and the disc tray, and the overflow weir is fixedly connected to the disc tray.

[0005] Preferably, a downcomer pipe is installed on the outer side of the lower end of the downcomer, the downcomer pipe is fixedly connected to the lower end of the disc tray, and the inside of the downcomer pipe penetrates through the downcomer.

[0006] Preferably, valve feet are installed at the lower ends of the valve holes in the middle of the disc tray.
