Internal mixing type bubble atomization oil gun

Abstract

The invention belongs to the technical field of industrial combustion and discloses an internal mixing type bubble atomization oil gun for realizing the purposes that the particle diameter of the atomization oil gun keeps small and uniform, the air is easily mixed with oil mists and combustion is full. The atomization oil gun comprises an oil gun shell and a mixing core arranged on the inner side of the tail of the oil gun shell and arranged coaxial with the oil gun shell and is characterized in that a plurality of first radial oil spraying holes are formed in the wall of a blind hole in the front end of the mixing core, a plurality of first axial atomization spraying holes are formed in the outer convex surface of the shoulder part of the mixing core, a fuel oil channel is formed in the inner side of a tail cylinder of the mixing core, and an atomization medium channel is formed between the outer side of the tail cylinder and the inner side surface of the oil gun shell; a guide cone is arranged on the inner side of the top of the front of the oil gun shell, an oil-air mixing chamber is formed between the guide cone and the outer side of the top end of the mixing core, the outer side of the front end of the oil gun shell is shaped like a circular truncated cone, and a plurality of second atomization spraying holes are formed in the inclined surface of the circular truncated cone. The atomization oil gun is simple in structure and suitable for combusting liquid fuel with impurities; by adopting the special design of the spraying holes of the gun head, combustion is full, black smoke is eliminated, and the ejection force is large.

Description

technical field [0001] The invention relates to a medium atomizing oil gun, in particular to a medium atomizing oil gun for industrial and power plant combustion with high efficiency, small atomizing particle size and large output. Background technique [0002] In recent years, with the extensive use of fuel gas equipment such as internal combustion engines, gas turbines, and boilers in the industrial field, and the sudden emergence of the petrochemical industry, environmental and energy issues have attracted more attention. Therefore how to improve the combustion efficiency of this type of equipment, energy saving and emission reduction has always been the focus of people's research. In these devices, the oil gun is required to atomize the fuel into tiny particles and then mix with the combustion air to burn. Therefore, the performance of the oil gun affects the ignition, combustion efficiency, combustion stability, and pollution emissions. The size of the atomized particl...

Problems solved by technology

However, today's atomizing oil guns are generally Y-shaped oil guns and ordinary internal mixing oil guns, which are difficult to match the air of high-output burners

In particular, oil guns with an output of more than 3.5t / h have large atomized particle sizes, and it is difficult for the combustion air to penetrate the oil mist layer, resulting in unstable combustion, black smoke, and flame tailing, which affect the normal operation of the boiler. In severe cases, it will affect the safety of the boiler

Patent No. 200810040516.3 is named "High Viscosity Liquid Fuel Venturi Rectification Atomization Oil Gun", which involves a membrane atomization oil gun technology, the output can reach about 5t / h, but the oil and gas channels of the oil gun are circular , the gap is small, and the requirements for oil products are high in industrial applications. Once there are small particles, the internal oil passage and air passage are easy to block
