Double-gas automatic adjustable atomizing nozzle

Abstract

The invention relates to a double-gas automatic adjustable atomizing nozzle which comprises a main body block, a spraying part and an angle-adjusting gas inlet channel. A negative pressure air inlet, an angle-adjusting gas inlet and a liquid inlet are formed in the main body block; a liquid inlet pipeline is coaxially arranged at the bottom end of the main body block and is communicated with the liquid inlet pipeline; the spraying part is fixedly connected with the bottom end of the main body block; a through opening is vertically formed in the top face of the spraying part in a penetrating mode; a negative pressure air channel is formed between the liquid inlet pipeline and the inner side wall of the through opening; the negative pressure air inlet communicates with the negative pressure air channel; the bottom face of the liquid inlet pipeline is flush with the bottom face of the negative pressure air channel; the angle-adjusting gas inlet channel is vertically formed in the outer side of the negative-pressure air channel; the angle-adjusting gas inlet is communicated with the angle-adjusting gas inlet channel; the angle-adjusting gas inlet channel and the negative-pressure air channel are closed; and an outlet of the angle-adjusting gas inlet channel is obliquely arranged towards the axis of the liquid inlet pipeline. The double-gas automatic adjustable atomizing nozzle provided by the invention has the advantages of being capable of conveniently and automatically adjusting the spraying angle, and adapting to different use working conditions.

Description

technical field [0001] The present application relates to the technical field of nozzles, in particular to a dual-gas automatic adjustable atomizing nozzle. Background technique [0002] The atomizing nozzle is a device that can atomize the liquid and suspend it evenly in the air. The atomizing nozzle can effectively increase the contact area between the liquid and the surrounding medium, so it is widely used in dust removal, combustion, sandblasting and other fields. According to its atomization principle, the atomizing nozzle can be divided into two atomization methods: mechanical atomization and medium atomization. Mechanical atomization relies on the high-speed jet generated by the liquid under the action of pressure difference to atomize itself; The gas at a certain pressure forms a high-pressure airflow, thereby breaking up the liquid ejected at a low pressure and completing the atomization. [0003] The atomization uniformity of medium atomization is better than tha...

Problems solved by technology

[0004] However, the atomization range formed by the atomization structure of this medium has been determined during the nozzle production process, that is, the shape and range of spray formation are basically fixed, and the common ones are fan-shaped, solid cone, etc., although in this In this atomization structure, increasing or decreasing the gas pressure can slightly change the range of spray coverage, but the change is small and unstable, because after increasing the air pressure, the liquid along the liquid column axis is easily overwhelmed. If the gas pressure is reduced, it is easy to make the center of the liquid column not be completely dispersed, which makes it difficult to form a spray in the spray center, resulting in a solid defect in the spray center. Significantly reduced uniformity of spray formation

[0005] Therefore, in view of the above situation, the inventor believes that the spray range of the atomizing nozzle in the related art cannot be well adjusted, and the uniformity of the spray formation is insufficient, so it is difficult to better adapt to different working conditions, such as different automatic batch spraying. Objects with a large surface area, or adjusting different spray ranges in the combustion chamber to meet the combustion needs, etc., resulting in troublesome use and general applicability
