Technical Field

[0001] The utility model relates to the technical field of super-temperature spraying, in particular to a super-temperature spraying device for grease purification. Background Art

[0002] Waste oil refers to the waste generated during cooking, frying, deep-frying and baking. Since waste oil causes great harm to the environment and human health, it must be properly handled.

[0003] After processing, waste grease can be used to produce biodiesel, and can also be used as raw material for producing soap and animal feed, etc. Therefore, waste grease has good renewability and environmental friendliness after processing.

[0004] Generally, waste oil needs to be dehydrated, impurity-removed, and acid-base neutralized before it can be reused. During this process, a large amount of waste gas will be generated. The waste gas contains a large amount of impurities and has a high temperature. If it is directly discharged into the atmosphere, it will not only pollute the environment, but also may endanger human health. Therefore, a waste gas cooling and impurity removal device is urgently needed. Utility Model Content

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0018] An ultra-temperature spray device for grease purification comprises a spray tank 1, wherein one side of the spray tank 1 is provided with a feed port 2, and the other side is provided with a discharge port 3, wherein the spray tank 1 is provided with a spray device 4, wherein the spray device 4 comprises a water inlet pipe 41, wherein the water inlet pipe 41 is connected to an annular water pipe 42, wherein the annular water pipe 42 is provided with a plurality of high-pressure atomizing nozzles 43 in a circular array, wherein each of the high-pressure atomizing nozzles 43 is provided with a filter screen 404 at the connection between the high-pressure atomizing nozzle 43 and the annular water pipe 42, wherein the high-pressure atomizing nozzle 43 is provided with a filter screen 404 ... The chemical spray head 43 includes a nozzle 5, an outer wall 44, and a liquid inlet cavity 45. Two compressed gas inlets 46 are provided on the outer wall 44. The compressed gas inlets 46 are arranged obliquely. Each of the compressed gas inlets 46 is connected to the gas outlet end of the air inlet branch pipe 6. The air inlet branch pipe 6 is arc-shaped. All of the air inlet branch pipes 6 are surrounded by a ring. Each of the air inlet branch pipes 6 is connected to a branch pipe 7. The branch pipe 7 is "L"-shaped. All of the branch pipes 7 are connected to the air intake main pipe 8. The air intake main pipe 8 is connected to the air pump 9. The air pump 9 sends the high-pressure gas into the air intake main pipe 8, and the air intake main pipe 8 then sends the high-pressure gas into the branch pipe 7 and the air intake branch pipe 6 in sequence, and then enters the liquid inlet cavity 45 through the compressed gas inlet 46. The oblique compressed gas inlet 46 can make the high-pressure gas fully act on the water in the liquid inlet cavity 45, and the water is more fully stimulated into high-pressure water mist.

[0019] Furthermore, the compressed gas inlet 46 is inclined at 30°-60°.
