Air exhausting device

Abstract

The invention discloses an air exhausting device. The air exhausting device comprises an air inlet pipe, an outer cylinder and an inner core arranged in the outer cylinder; the inner core is installed in the outer cylinder, the upper portion of the inner core is formed by stacking multiple bubble generating devices, the periphery of each bubble generating device is provided with more than six transverse protrusions, and the protrusions on the bubble generating devices which are vertically stacked are stacked together in a mutually staggered mode. According to the air exhausting device, the upper portion of the inner core is composed of the more than six bubble generating devices, the periphery of each bubble generating device is evenly provided with more than six protrusions to form a relatively narrow air channel, and the bubble generating efficiency is high. The other inner core of the air exhausting device is composed of multiple sets of pressure-changing bubble generating devices, the number of the protrusions on the periphery of the bubble generating device located on the upper portion is larger than that of the protrusions on the periphery of the bubble generating device located on the lower portion in each set of the pressure-changing bubble generating devices, the protrusions on the bubble generating devices are mutually staggered, air channels are not formed in the surface of the inner core, therefore, air waste caused by air channel forming is avoided, and the generating efficiency of micro bubbles is improved.

Description

technical field [0001] The invention relates to the technical field of micro-bubble generators, in particular to an air diffuser. Background technique [0002] The principle of micro-bubble generation is basically that the gas is turned into bubbles by the impact of the protrusions on the inner wall of the tube against the cutting effect. The entire bubble generation process is carried out in the entire cylinder with a relatively large space. and the size of the bubbles) are greatly affected by the ratio of air and water entering the cylinder, so it is difficult to control the optimal air-water ratio in actual operation, so it is difficult to achieve ideal working efficiency, and in the circular At the center of the cylinder, the protrusions cannot reach, and a lot of air bubbles will fly out of the cylinder from the center of the cylinder without being broken and cut, so the generation efficiency of tiny air bubbles is low. On the other hand, because the bubbles are broken...

[0002] The principle of micro-bubble generation is basically that the gas is turned into bubbles by the impact of the protrusions on the inner wall of the tube against the cutting effect. The entire bubble generation process is carried out in the entire cylinder with a relatively large space. and the size of the bubbles) are greatly affected by the ratio of air and water entering the cylinder, so it is difficult to control the optimal air-water ratio in actual operation, so it is difficult to achieve ideal working efficiency, and in the circular At the center of the cylinder, the protrusions cannot reach, and a lot of air bubbles will fly out of the cylinder from the center of the cylinder without being broken and cut, so the efficiency of generating tiny air bubbles is low

On the other hand, because the bubbles are broken by the impact cutting principle of the protrusions, if the speed of the airflow rising is not controlled too fast, the microorganisms in the water are easily killed by the impact cutting of the protrusions. If the speed is too slow, the impact and cutting force on the air bubbles will be insufficient, and the effectiveness of tiny air bubbles will be greatly reduced
