The invention discloses an injection spray pipe for a gas copious cooling liquefying system and a system of the injection spray pipe. The injection spray pipe comprises an outer spray pipe body and an inner spray pipe body located in the outer spray pipe body; the outer spray pipe body is sequentially composed of a cylinder segment, a mixed pipe segment and a diffusion pipe segment; the mixed pipe segment is of a gradual-shrinking structure, and the end close to the cylinder segment is the large-diameter end; the diffusion pipe segment is of a conical structure, the end close to the mixed pipe segment is a small-diameter end, at least one passive flow connecting pipe is connected to the wall of the cylinder segment, a nozzle is arranged in the inner spray pipe body, and one end of the nozzle is connected with an active flow pipeline; and a connecting plate is arranged on the active flow pipeline, and the active flow pipeline and the nozzle are connected into the cylinder segment on the outer spray pipe body through the connecting plate. The injection spray pipe is simple in whole structure, low in cost and capable of adapting to the gas copious cooling liquefying environment of the high-temperature-difference, high-pressure-difference and high-impact environment.
Description
technical field [0001] The invention relates to the field of gas liquefaction equipment, in particular to an injection nozzle for a gas cryogenic liquefaction system and a system thereof. Background technique [0002] The gas high-pressure jet liquefaction process has been widely used in the field of cryogenic liquefaction due to its advantages of flexible start-up and fast liquid discharge. It is difficult to meet the requirements of the injection nozzle and its system. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention proposes a gas cryogenic liquefaction system with a simple structure, which can well adapt to high temperature difference, high pressure difference, and high impact environment, and its system. The specific technical scheme is as follows: [0004] An injection nozzle for a gas cryogenic liquefaction system, comprising an outer nozzle (1) and an inner nozzle (2) inside the outer nozzle (1), wherein the ou...
