Enhanced atomization fuel spray gun

Abstract

The invention relates to an enhanced atomization fuel spray gun. The enhanced atomization fuel spray gun includes a gun rod, a spray head, an oil-gas mixing core and an oil-gas mixing chamber, whereinthe oil-gas mixing core is added with multiple special channels for high-speed high-pressure atomization medium on the basis of normal setting, the oil-gas mixing chamber is a venturi mixing chamberof which an inner surface is irregular, during operation, the atomization oil and gas normally injected into the oil-gas mixing chamber and injected into a furnace can be subjected to deep atomizationin the high-pressure environment through repeated impact, collision, tearing, continuous surface tension reduction and oil droplet refinement in the venturi mixing chamber with the irregular surfaceshape with the high-speed high-pressure atomization medium from a dedicated channel, atomization efficiency is improved, atomization quality is guaranteed, the outward jet impact force is enhanced, compared with a similar fuel spray gun in the prior art, the better atomization effect, greater output, smoother jet and larger jet range are achieved, fullness of the flame in the furnace is guaranteed, occurrence of clogging of nozzles and black smoke from boilers can be further avoided, the significant energy saving and discharge effect of the boiler is achieved, and strong practicality is achieved.

Description

technical field [0001] The invention relates to the technical field of liquid fuel atomization devices, in particular to an enhanced atomization type fuel spray gun with good atomization effect, high efficiency and large output. Background technique [0002] In recent years, with the extensive application of oil in internal combustion engines, gas turbines, industrial boilers and other fuel gas equipment, how to improve the combustion efficiency of fuel oil and achieve energy saving and emission reduction has become a topic of general concern in the industry. When oil fuel is used, it must be atomized into tiny particles with the aid of a fuel spray gun in order to fully mix with the combustion-supporting air to achieve efficient combustion, energy saving and emission reduction. Therefore, the performance of the fuel spray gun is closely related to the particle size of the atomized fuel, the output of the sprayed oil mist, and whether the generated oil mist layer can be easi...

AI Technical Summary

Problems solved by technology

Medium-atomized fuel spray guns are becoming more and more popular due to their relatively simple structure, small size, convenient use, and low energy consumption. However, in practice, it is found that the particles of the atomized fuel are not fine enough and the injection force is not enough. Therefore, during the working process, poor injection, pressure suppression in the oil-gas mixing channel, coke on the nozzle surface, and even blockage will occur, resulting in a small and uneven injection range of atomized oil and gas, and fuel combustion in the furnace. Insufficient, the boiler is prone to black smoke, the utilization rate of fuel oil is low, and the phenomenon of waste is serious, so it is not ideal from the perspective of economy and practicability
