Jet type natural gas drag reducer premixing device

Abstract

The invention discloses a jet type natural gas drag reducer premixing device which comprises a shell, a natural gas inlet is formed in one end of the shell; two drag reducer inlets are centripetally formed in the side surface of the end along the circumference of the shell; an atomized corrosion inhibitor outlet is formed in the center of the other end of the shell; a jet flow sprayer tail supporting plate, two sets of gas-liquid jet flow sprayers, a jet flow sprayer head supporting plate, a spiral blade and a reducing throttle pipe are sequentially arranged in the shell. A natural gas jet flow sprayer is arranged in the center of each set of gas-liquid jet flow sprayers, the natural gas jet flow sprayers and the gas-liquid jet flow sprayers are concentrically installed, each set of gas-liquid jet flow sprayers corresponds to one drag reducer inlet, and a space formed by a jet flow sprayer tail supporting plate and a shell at the natural gas inlet end is a natural gas buffer cavity. Byusing the device, the natural gas and the drag reducer can be uniformly mixed through the effects of jet flow atomization mixing, spiral atomization mixing, throttling atomization mixing and the like.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid mixing, in particular to a jet-type natural gas drag reducer premixing device. Background technique [0002] For long-distance natural gas pipelines, the pressure loss of gas in the pipeline is an important issue. When the gas is in the turbulent region, especially the high Reynolds number region, due to the existence of turbulence and other irregular motions, the pressure loss caused by the gas energy loss is much larger, and the roughness of the tube wall is the main reason for the eddy flow. Therefore, reducing the pressure loss by reducing the roughness of the gas pipeline has become the main means to increase the gas flow.

Problems solved by technology

[0003] Pipeline inner coating drag reduction technology is generally used at home and abroad to reduce pipe wall roughness, but the construction equipment of pipeline inner coating drag reduction technology is complex and expensive, and the drag reduction effect gradually decreases or even decreases as time goes by due to the continuous peeling off of the inner coating. Produce negative effects, and at the same time, the original non-coated pipeline cannot be implemented due to construction costs and other issues
