Description

[0002] In industrial burners, various fuels are transported to the nozzle device through pipelines and then ignited and burned. The structure of the transport pipeline and the nozzle device in the burner is usually called a combustion gun, such as a gas gun, a coal powder gun, an oil gun, etc. However, due to its structural limitations, the existing oil guns mostly use a single oil as fuel, while emulsified oil has the advantages of less pollution and good combustion effect. At present, the industry gradually uses emulsified oil as the fuel of oil guns.

Water directly enters the oil gun body 1 through the water inlet inner sleeve 4, and oil directly enters the oil gun body 1 through the oil inlet inner sleeve 3, and is preliminarily mixed in the mixing chamber 35 in the oil gun body 1. After the mixed oil and water enter the atomizer 2, they gradually form a fine mixture of oil-in-water, oil-in-gas, and oil-in-gas and water under the action of compressed air, and reach the nozzle end 12 under the action of compressed gas, and are sprayed out from the oil spray hole 121 of the nozzle end 12 to form an atomized state.

The retention chamber 26 of the atomizer 2 is penetrated by a nut, and the fixing column 28 is fixed to the retention chamber 26 of the atomizer 2. One end of 28 is fixed in the retention chamber 26, thereby limiting the fixing column 28, so that the fixing column 28 will not be separated from the retention chamber 26. The spring 29 is set between the atomizer 2 and the conical head 281. When water impacts the conical head 281, the conical head 281 always maintains the rebound and buffering effect under the elastic force of the spring 29. This arrangement allows the water coming out of the water outlet 42 to quickly disperse to various positions of the mixing chamber 35 after colliding with the conical head 281, thereby accelerating the mixing speed of water and oil.
