Problems solved by technology
Since the density of liquid is much higher than that of gas, the liquid injected through the water injection pipe enters the oil and gas pipeline in the form of columns or raindrops, and then gathers and flows at the bottom of the pipeline along the wind direction of the oil and gas. The gas-liquid contact area is small and the mixing is not sufficient
On the one hand, the conventional liquid injection process has a low utilization rate of liquid, which leads to poor washing effect of ammonium salt, and the deposited ammonium salt causes corrosion under scale; on the other hand, insufficient contact between gas and liquid leads to large consumption of liquid, and some More expensive, such as neutralizing corrosion inhibitors, etc., increasing production costs

Embodiment Construction
[0018] The present invention can be explained in detail through the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.
[0019] combined with figure 2 The above-mentioned method and device for adjusting the nozzle spray angle on-line comprise a swirl chamber 1 and an external control system. The equipment divides the liquid entering the nozzle into two paths through two coaxially arranged pipes, one path enters the swirl chamber 1 through the radial hole 2, and the other path enters the swirl chamber 1 through the axial hole 3, and the two paths of liquid pass through Independent control systems to control flow.
[0020] Implement a method and equipment for adjusting the nozzle spray angle on-line according to the present invention. When working, when the axial liquid channel is closed, the liquid enters the swirl chamber 1 through the radial hole 2 and rotates, then acce...

The invention relates to a method and a device for on-line adjusting a spraying angle of a nozzle. The device comprises a swirling flow chamber (1), radial holes (2), axial holes (3) and external control systems. According to the device provided by the invention, a liquid entering the nozzle is divided into two paths through a pair of coaxially arranged pipelines with unequal diameters; one path of liquid enters the swirling flow chamber (1) through a group of same uniformly distributed radial holes (2) with equal eccentric distances; and the other path of liquid enters the swirling flow chamber (1) through a group of axial holes (3) uniformly distributed along a circumferential direction. According to the device provided by the invention, a radial speed and an axial speed of the liquid inthe swirling flow chamber are controlled through adjusting the radial liquid flow and the axial liquid flow by the two paths of independent control systems, so that expected flow, spraying angle andmist form are obtained. The nozzle provided by the invention is multifunctional, flexible, reliable, and convenient for mass production.
Description
【Technical field】 [0001] The invention relates to a method and equipment for adjusting the spray angle of nozzles on-line, which is suitable for industries requiring liquid atomization such as oil refining, chemical industry, papermaking, metallurgy and gardening, and is especially suitable for washing oil gas or flue gas in the field of petrochemical industry. 【Background technique】 [0002] In order to meet the production requirements of anti-corrosion, washing and mixing, oil refineries usually inject a certain amount of liquid into the gas phase. Water injection in oil and gas pipelines can not only wash the ammonium salts generated by the reaction between ammonia and acidic media in oil and gas, prevent ammonium salts from clogging pipelines or absorbing acidic media to cause corrosion and perforation, but also adjust the temperature of oil and gas by controlling the amount of water injected, and artificially change the position of the initial setting zone , reduce the ...
