Abstract

The invention provides a liquid distributor, a multi-stage efficient distributor containing the liquid distributor and suitable for liquid spraying and an arrangement method of the multi-stage efficient distributor. The liquid distributor comprises a vertical cylinder, the cylinder comprises a feeding cavity at the upper portion and a distribution cavity at the lower portion, spiral blades are annularly arranged on the inner wall of the feeding cavity, the inner side edges of the spiral blades are connected to a vertical fixing column, the distribution cavity comprises a plurality of partitionplates, the partition plates divide the distribution cavity into a plurality of independent cavities, a through hole is formed in the outer wall of each independent cavity, and an outlet pipe is connected to each through hole. The efficient distributor may include a multi-stage distributor. The liquid distributor serves as a center distributor, each outlet pipe is connected with a second-stage distributor through a connecting pipe, each second-stage distributor comprises an outlet pipe, the outlet pipes are downwards connected with vertical extending pipes, and the bottoms of the vertical extending pipes are connected with nozzles. The liquid distributor and the efficient distributor are simple in structure, uniform in fluid distribution, sufficient in coverage area and high in washing efficiency, and meanwhile a modular structure enables installation and maintenance to be more convenient.

Description

technical field

[0001] The invention belongs to the technical field of gas purification, and in particular relates to a liquid distributor, a multi-stage high-efficiency distributor suitable for liquid spraying and a method for spraying washing liquid by using the high-efficiency distributor. Background technique

[0002] In the petrochemical production process, when there are other types of gases or solid particles in a certain gas, it is sometimes necessary to spray and wash the gas to remove impurity gas components or solid particles, or to recover mixed gases through solvents one or several gas components.

[0003] The main advantage of spray scrubbers over other scrubbers is the completely open design: there are no internal parts other than the nozzles, a feature that eliminates many of the fouling and clogging problems associated with other scrubbers.

[0004] In a spray scrubber, absorption can be increased by reducing the droplet size or increasing the liquid-to-gas...
