Problems solved by technology

Packed towers also have some disadvantages, such as high packing cost; when the liquid load is small, the surface of the packing cannot be effectively wetted, which reduces the mass transfer efficiency; it cannot be directly used for materials with suspended solids or easy polymerization; side feed and Complicated rectification such as discharge is not suitable, etc.

Embodiment

[0019] A combined packing in this embodiment is formed by splicing and combining several random packings. The structure of the random packing is as follows: figure 1 , 2 As shown, the random packing includes a three-dimensional annulus with upper and lower openings and several inner tongues 1, the three-dimensional annulus is also provided with a window, the middle position of the window is provided with a connecting bridge 2, and one end of the inner protruding tongue 1 is arranged on the connecting Bridge 2; a card slot 3 with the same width as the connecting bridge 2 is arranged between the window and the window, and the outer opening of the card slot 3 is provided with a buckle for making the connecting bridge 2 and the card slot 3 snap fit.

[0020] The upper end of the combined packing in this embodiment is provided with several funnel-shaped collectors.

[0021] The inside of the random packing of this embodiment is coated with an oleophobic coating.

[0022] The oleo...

Abstract

The invention relates to combined packing, and belongs to the technical field of physical separation operation devices. The combined packing is formed by splicing and combining a plurality of piles of random packing. Each pile of random packing comprises a solid annular face with the upper and lower open ends and a plurality of inward-extending tongue pieces, wherein the solid annular face is provided with windows, connecting bridges are arranged in the middles of the windows, and one ends of the inward-extending tongue pieces are arranged on the connecting bridges. Clamping grooves with the same width as the connecting bridges are arranged between the windows. Buckles enabling the connecting bridges and the clamping grooves to be clamped and matched are arranged on outlets of the clamping grooves. The combined packing is formed by splicing and combining the multiple piles of random packing; coating is carried out on the spliced joints and the interiors of the random packing, so that the overall passing ability of the combined packing is improved; the certain distributor effect can be achieved by programming different hopper-shaped collectors, and the overall utilization rate of the combined packing is improved.

Description

technical field [0001] The invention relates to a combined packing, which belongs to the technical field of physical separation operation devices. Background technique [0002] Gas-liquid mass transfer equipment is essential in unit operations such as absorption, desorption, rectification, and extraction, which are widely used in the chemical industry and the petroleum industry. Tower equipment is one of the gas-liquid mass transfer equipment that makes gas-liquid into two phases and achieves the purpose of interphase mass transfer and heat transfer through precise contact. [0003] Tower equipment is generally divided into two categories: interstage contact type and continuous contact type. The representative of the former is a plate tower, and the representative of the latter is a packed tower. Among various tower types, the most widely used ones are sieve plate tower and valve tower. [0004] The packed tower is a mass transfer device in which the packing in the tower i...
