Environmental fume processor

Abstract

The invention provides a cooking fume treatment machine with high environmental friendliness. The cooking fume treatment machine comprises a centrifugal fan. An air inlet of the centrifugal fan faces downwardly, and an air outlet of the centrifugal fan comprises fan blades which are peripherally arrayed; an annular wall is arranged on the outer periphery of the centrifugal fan, an air annular layer with the radial thickness of 5-15mm is formed between the annular wall and the centrifugal fan; a filter screen plate covers the upper end of the air annular layer; a liquid condensing structure is arranged on the annular wall, an oil collecting vessel is arranged at the lower end of the annular wall, and an air pipe is connected to the upper end of the annular wall. The cooking fume treatment machine has the advantages that the oil and gas separation efficiency can be obviously improved, and the cooking fume treatment machine is favorable for protecting atmospheric environments.

Description

technical field [0001] The invention relates to the field of kitchen environmental protection equipment, in particular to a cooking fume processor. Background technique [0002] The range hood is one of the necessary equipment in the modern kitchen. It is mainly used to extract the oil fume generated by the cooking stove, and after separating the oil and gas, it is discharged into the air. In the current range hood, the main component of oil and gas separation, namely the filter screen, is arranged at the bottom of the range hood. When the oil fume rises, it first passes through the filter screen, and the oil droplets in the oil fume condense on the filter screen, thereby realizing oil and gas Separated, the remaining air enters the duct and is exhausted to the outside world. During this process, since the oil fume passes through the filter screen at a near vertical angle, the contact area between the oil fume per unit volume and the filter screen is small, and the contact ...

AI Technical Summary

Problems solved by technology

During this process, since the oil fume passes through the filter screen at a near vertical angle, the contact area between the oil fume per unit volume and the filter screen is small, and the contact time is short, resulting in a large amount of oil fume directly passing through the filter screen, and only a part of the oil droplets condense on the filter screen. It can be seen that the oil and gas separation efficiency of this traditional range hood is low, resulting in a large amount of oil and gas being discharged into the air, which is not conducive to the protection of the atmospheric environment
