Atomization filling device

Abstract

The invention relates to the technical fields of medicament test and pipe systems, and specifically relates to an atomization filling device. An atomization cavity is of a spindle body structure, oneend of the atomization cavity communicates with a gas outlet of a filling chamber, and the other end of the atomization cavity communicates with a test pipe; a double-fluid atomization nozzle is formed in one end close to the filling chamber, in the atomization cavity, and in a manner of being coaxial with the atomization cavity, a liquid-phase inlet of the double-fluid atomization nozzle communicates with a liquid conveying pipeline, a drag reducer solution enters the double-fluid atomization nozzle through the liquid conveying pipeline, a gas-phase inlet of the double-fluid atomization nozzle communicates with a gas conveying pipeline, and an auxiliary gas enters the double-fluid atomization nozzle through the gas conveying pipeline; and compressed air enters the filling chamber and theatomization cavity through a gas inlet of the filling chamber. According to the atomization filling device provided by the invention, only one nozzle is used under the condition of no need of providing a high pump pressure, and preparation for the drag reducer solution with an atomization particle size of 5-40[mu]m can be realized through simple and flexible adjustment.

Description

technical field [0001] The invention relates to the technical field of chemical testing and piping systems, in particular to an atomization filling device, and more particularly to a natural gas drag reducer atomization filling device using a two-fluid atomization nozzle. Background technique [0002] At present, the consumption of a large amount of fossil fuels has led to the deterioration of the natural environment, making people's demand for natural gas, a clean energy source, increasing day by day, so that the load on existing gas transmission pipelines is increasing. Therefore, improving the transmission capacity of existing gas transmission pipelines has become a An important research direction of the petrochemical industry. [0003] The existing methods are generally to take necessary measures to reduce pipeline resistance, and then achieve the purpose of increasing transportation, and the synthesis and application of natural gas drag reducer has become an important m...

Problems solved by technology

Then, the larger pump pressure will lead to an increase in the risk factor during operation, and the narrow pump pressure range will result in a limited amount of drag reducer solution that can be freely adjusted under ideal atomization conditions

In addition, in the process of studying the effect of drag reducer solution filling amount and atomized particle size on the adsorption and film formation of the pipe wall, the single-fluid atomizing nozzle is used, the operation is relatively complicated, and it is difficult to achieve the predetermined adjustment target
