Strong tornado generator

Abstract

The invention discloses a strong tornado generator, which comprises an outer frame formed by an air inlet pipe, a whirlwind shell and a linking sleeve. An inner cone, a whirlcone and anti-whirlpool plug are mounted in the outer frame. The generator also comprises a middle linking sleeve arranged between the outer frame and the inner cone and the whirlcone, wherein the middle linking sleeve is matched and connected to the whirlwind shell and the whirlcone; two types of round holes are uniformly distributed on a conical section of the whirlcone; the axis of one type of round hole is tangent with an inner wall of the cavity; the generatrix of the other type of round hole is tangent with the outer wall of the cavity; and an included angle alpha between the round hole axis on the same cross section and the upright direction is from 5 to 30 degrees. The invention has the advantages of enhancing the air flowing energy, increasing the air flowing penetrating force and impact force, and being convenient to manufacture and mount.

Description

technical field [0001] The invention relates to an auxiliary air intake equipment for a metallurgical furnace, in particular to a powerful tornado generator for increasing the air intake intensity of a metallurgical furnace. Background technique [0002] In the metallurgical smelting industry, improving the combustion effect of coke is a very key technology to improve the smelting effect. In the process of combustion and smelting, the air inlet device on the metallurgical furnace is an indispensable equipment, and it also plays a very important role in the combustion effect of pulverized coal in the combustion chamber. Among the commonly used air inlet devices at present, the air inlets are tube-type air inlets, and the principle of its air supply is not essentially different from the air flowing in nature. The air inlet device is used to make the air enter the center of the furnace, so that coke and coal The powder burns fully, but for different devices, the strength of th...

[0004] ① The structure of the "tornado effect body" at all levels not only increases the manufacturing difficulty, but also the several rows of tangential and different forward-inclining air inlet holes on the "tornado effect body" at all levels are only tangential to the "tornado effect body" at each level. The inner wall of the "tornado effect chamber", thus adding a "tornado effect chamber" at all levels. Under the action of the centrifugal force of the rotating air flow, a recirculation space is formed on the inner side of the "tornado effect chamber", which produces a recirculation airflow in the opposite direction to the main airflow. In vain self-consumption of the energy of the main air flow;
