Description

High-speed high-efficiency nozzle

Technical Field

The utility model relates to a shower nozzle equipment technical field particularly, especially relates to a high-speed high-efficient nozzle.

Background

In the paper industry, chemicals including cleaning agents, pitch control agents, stain-proofing agents, release agents, and the like have been supplied to parts of paper machines such as wires, felts, drying rolls, and canvas for the purpose of preventing transfer of foreign matters from pulp raw materials from the paper body, improving the efficiency of paper removal, and the like.

In general, these chemicals are supplied from nozzles of a nozzle device attached to a paper machine to a paper body, a wire, a felt, a drying roll, a canvas, and the like (hereinafter referred to as "moving body") in a state where the paper machine is started.

However, since the moving body moves at a high speed, an air flow (hereinafter referred to as "follow-up air flow") is generated in the vicinity of the surface of the moving body along the movement, and the chemical liquid discharged from the nozzle to the moving body is curled up by the follow-up air flow.

Therefore, not only the chemical liquid cannot be sufficiently supplied to the mobile body, but also the following problems occur: that is, the wound-up chemical adheres to a machine frame, a hood, or the like to contaminate the paper machine.

As a device for preventing such a liquid medicine from rolling up, there has been proposed a fluid scattering prevention device for fluid dispersion which forms an air curtain between an upstream side and a downstream side of a nozzle for ejection of a fluid (liquid medicine) and sprays the fluid in a space therebetween.

According to this apparatus, in a conventional paper making machine having a low paper making speed, almost all of the chemical liquid reaches the moving body, and the above-described problem can be solved.

However, in recent years, paper machines have been developed to be very high-speed, and paper machines having a paper making speed of 1500 to 2000m/min have appeared.

In such an ultra-high-speed paper machine, since the following air flow around the moving body is an air flow having extremely strong wind speed and wind pressure, the chemical liquid cannot be sufficiently supplied to the moving body and the scattering of the chemical liquid cannot be sufficiently suppressed in the above-described apparatus.

There is a tendency that the following air flow around the moving body is greatly disturbed and generated by the air curtain.
