Embodiment 1

[0041] Such as figure 1 As shown, this structure is a jet drainage structure including a liquid medium flow guide and a gas medium flow guide, mainly including the air flow nozzle, the decontamination liquid nozzle and the confluence arc surface, the arc of the confluence arc surface is 35°, the arc The length is L, the radius is R, the air flow nozzle (jet port of B medium guide piece) is located at one end of the confluence arc surface, and the decontamination liquid nozzle (A medium guide piece jet port) on the confluence arc surface, decontamination The arc length between the liquid nozzle and the air nozzle is l;

[0042] The gap width of the airflow spout (jet outlet of medium guide member B) is D, and the gap width of the decontamination nozzle (jet outlet of medium guide member A) is d, where D is greater than d;

[0043] The air flow nozzle includes an upper surface and a lower surface. The upper surface is connected to the confluence arc surface through an arc surfa...

Embodiment 2

[0048] Such as figure 2 As shown, this structure includes a nozzle main body, and two parallel connecting pipes are arranged at the tail of the nozzle main body. A flow pipe, wherein the liquid flow medium guide pipe is located at the upper part of the air flow medium guide pipe, and a main flow channel is also arranged at the lower part of the air flow medium guide pipe and the liquid flow medium guide pipe;

[0049] The main flow channel is formed by two arc-shaped surfaces C at intervals. Between the two arc-shaped surfaces C is the main flow guide channel. The main flow guide channel mainly includes a drainage section and a confluence section. The outlet of the medium diversion pipe is located on the diversion section, and the high-pressure fluid ejected from the air medium diversion pipe and the liquid flow medium diversion pipe converge at the confluence section, wherein the width of the confluence section is much larger than that of the diversion section;

Embodiment 3

[0056] Changing the flow rate of the gas medium fluid and the liquid medium fluid by changing the working load of the gas medium fluid and the liquid medium fluid driving the pump;

[0057] By adjusting the flow rate of the gaseous medium fluid to be A, wherein because the diameter of the air flow nozzle is constant, there is a linear relationship between the flow rate and the flow rate;

[0058] By adjusting the liquid medium fluid, the flow rate is B, wherein because the diameter of the liquid flow nozzle is also constant, there is a linear relationship between the flow rate and the flow rate;

[0059] At this time, adjusting the mixing relationship between A and B can obtain mixed jets in different states.

[0060] 1. Adjust A so that A is greater than 0, and B is adjusted to be equal to 0. At the same time, A must meet the resistance along the surface of the confluence arc surface. At this time, a thin surface-shaped gas fluid of pure gas will be obtained, which can be mai...

Abstract

The invention relates to a method for generating a mixed jet and its drainage structure, the structure includes A medium flow guide, B medium flow guide and a confluence arc surface; the jet axis of the A medium flow guide and B medium flow guide and the The confluence arc surface is tangent; a jet end is provided at the end of the confluence arc surface, the total length of the arc surface from the jet end to the jet port of the A medium guide piece is l, and the total length of the arc surface from the jet end to the B medium guide piece jet port is L, wherein L is greater than 1; the method includes: the direction of the jet flow of the A medium guide member moving along the confluence arc surface is the same as the direction of the decontamination liquid nozzle moving along the confluence arc surface, and the decontamination liquid is driven by the high-speed airflow along the After optimization, the surface is sprayed to form a thin layer of water curtain or curtain-like water droplets. At the same time, different decontamination effects can be achieved by adjusting the mixing ratio of gas and liquid, and the versatility is relatively high.

Description

technical field [0001] The invention relates to a method for generating mixed jets and a drainage structure thereof, belonging to the field of decontamination equipment. Background technique [0002] According to the relevant requirements of the latest "Guidelines for the Research of Logistics Science and Technology of the Whole Army (2014-2017)", design a system that meets the major needs of medical support when encountering biological, chemical or nuclear weapons attacks, or related unexpected emergencies, especially The decontamination equipment meets the needs of economical and efficient decontamination when encountering biological, chemical and nuclear weapons attacks or accidents in the case of water shortage in field battles, tunnel operations, long-term voyages of ships (especially submarines), etc. One of the major security issues of concern; [0003] At present, the conventional three-proof decontamination uses water guns and sprayers to spray flowering jets or mi...
