A liquid pressure nozzle

Abstract

The invention discloses a liquid pressure nozzle to solve the problems of insufficient mixing depth, large resistance and the like of an alkylation reactor using an existing static mixer, fiber membrane or mechanical stirrer for mixing and distributing liquid concentrated sulfuric acid and iso-butane. The liquid pressure nozzle comprises a main pipe (3), and an inner cavity (4) of the main pipe (3) comprises an upper cylindrical inner cavity and a lower inverted conical inner cavity, Two inlet pipes (1) are arranged on two opposite sides of the main pipe respectively, and an inlet pipe inner hole (2) of an outlet end of each inlet pipe is communicated with the cylindrical inner cavity along the tangential direction of the cylindrical inner cavity. A disturbed flow element (5) is arranged at the top end of the cylindrical inner cavity, a throat (6) is arranged between the bottom end of the inverted conical inner cavity and the top end of a conical nozzle outlet (7), and a disturbed flow groove (8) is formed in a conical surface of the nozzle outlet and surrounds the axis line of the main pipe. The liquid pressure nozzle is mainly used for mixing, atomizing and distributing the liquid concentrated sulfuric acid and the iso-butane in the alkylation reactor.

Description

technical field [0001] The invention relates to an internal component of petroleum refining and chemical equipment, in particular to a liquid pressure nozzle. Background technique [0002] In the alkylation reactor of petroleum refining and chemical industry, it is required to achieve sufficient mixing and distribution of two liquid materials (liquid concentrated sulfuric acid and isobutane). The physical and chemical properties of the two liquids are different, especially they are not compatible with each other; to achieve the mixing and distribution between them, static mixers, fiber membranes or mechanical stirrers are mainly used at this stage. However, the use of static mixers, fiber membranes or mechanical agitators has the following problems: (1) the mixing depth of static mixers and fiber membranes is not enough, the mixing effect is poor, and the resistance is large; (2) mechanical agitators can Deep mixing is achieved, but the energy consumption is high; at the sa...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a liquid pressure nozzle to solve the mixing and distributing of liquid concentrated sulfuric acid and isobutane when the alkylation reactor uses the existing static mixer, fiber film or mechanical agitator. Insufficient depth, high resistance, prone to failure, etc., and existing liquid pressure nozzles cannot be used in the alkylation reactor for mixing and distribution of two liquids (liquid concentrated sulfuric acid and isobutane)
