Problems solved by technology

Another important feature of the rotating disk column is that it can handle the extraction system containing solid particles, but it is only suitable for low solid content operation. When the solid content of the system is too high, the solid phase is easy to deposit on the tray, and due to the sticky particles between the particles Accumulate gradually through the attachment effect, affect the extraction operation, and even cause blockage of the tower body

Embodiment 1

[0021] An improved internal component of a turntable column suitable for solid-containing extraction operations, which includes a turntable and a fixed ring, and is characterized in that the turntable and the fixed ring are designed in an arc shape.

[0022] Technically speaking, the radian on the fixed ring and the turntable matches the vortex formed by the multiphase fluid of the material in the tower to prevent the generation of flow dead zone;

[0023] The upper side of the fixed ring is processed into a streamline arc suitable for the multiphase flow field, or the upper and lower sides of the fixed ring are simultaneously processed into a streamline arc suitable for the multiphase flow field.

[0024] The upper side of the turntable is processed into a streamline arc suitable for the multiphase flow field, or the upper and lower sides of the turntable are simultaneously processed into a streamline arc suitable for the multiphase flow field.

[0025] The diameter of the ar...

Abstract

The invention relates to an improved rotating disc tower internal component suitable for solid-containing extraction operation. The component comprises rotating discs and fixed rings, and the rotating discs and the fixed rings are in an arc-shaped design. The radian on the fixed rings and the radian on the rotating discs are matched with eddies formed by multiphase fluid of materials in a tower. According to the improved rotating disc tower internal component suitable for solid-containing extraction operation, fixed rings and rotating discs of a traditional rotating disc tower are improved, the arc-shaped interface design structure is adopted, the multiphase flow field structure in the rotating disc tower can be well matched with the geometrical interface of the tower, flowing dead areas in the tower are eliminated, hence, the turbulence characteristic in the tower can be fully utilized, solid phase deposition is prevented, and the processing capacity of the rotating disc tower to a solid-containing extraction system is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical extraction, in particular to an improved internal component of a rotary tower suitable for solid-containing extraction operations. 【Background technique】 [0002] Extraction is one of the important unit operations in chemical separation engineering. Generally speaking, the extraction system is liquid-liquid two-phase, but there are also solid-containing extraction systems represented by liquid-solid and liquid-liquid-solid systems in industry. The solid particles in the extraction system are easy to form deposits in the extraction equipment or cause equipment blockage, which affects the normal operation of the extraction equipment. Therefore, the development of equipment suitable for solid-containing extraction operations is a problem that needs to be solved in industrial production. [0003] The rotary column is one of the most common extraction equipment in the industry. It has a series of a...
