Centralized cooking oil fume treating and recycling system

Abstract

The invention discloses a centralized cooking oil fume treating and recycling system which comprises an early-stage pretreatment unit, an electrostatic purification oil removal unit with a pump oil removal function, a later-stage air purification unit and an exhaust fan, wherein the early-stage pretreatment unit, the electrostatic purification oil removal unit, the later-stage air purification unit and the exhaust fan are sequentially connected through pipelines along the oil fume running direction; the electrostatic purification oil removal unit comprises a high voltage electric field generating area, a high voltage cathode electrode, a high voltage anode electrode, an oil pump, a hydraulic pressure gauge and a detachable collection container; the high voltage electric field generating area is formed in an oil fume inlet of the electrostatic purification oil removal unit; the high voltage cathode electrode and the high voltage anode electrode are vertically opposite to each other; the high voltage anode electrode is connected with the hydraulic pressure gauge, and oil on the high voltage anode electrode can be discharged into the collection container through the oil pump along the pipeline. Energy in the waste oil fume is utilized to the greatest degree when an electrostatic treatment device is not required to be detached, so that the device is simplified, and the aims of energy conservation and environment friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of kitchen oil fume treatment and recovery, in particular to a centralized treatment and recycling system for kitchen oil fume. Background technique [0002] In the daily society, households deal with waste cooking fume mainly by discharging it out of the environment through range hoods, which causes serious pollution. Relevant studies have shown that cooking fume is a group of mixed pollutants with extremely complex components, with as many as 200 to 300 species, including known mutagens and carcinogens such as volatile nitrosamines. Oil fume pollution has become an important source of pollution that cannot be ignored in today's society, seriously threatening the environmental quality of society and the health of citizens. [0003] The existing technology is aimed at purifying indoor oil fume, absorbing and treating toxic substances in the oil fume through physical and chemical means. There are a large num...

AI Technical Summary

Problems solved by technology

[0003] The existing technology is aimed at purifying indoor oil fume, absorbing and treating toxic substances in the oil fume through physical and chemical means. There are a large number of patent applications, but its limitations often lie in the following three points: 1. Waste oil fume becomes household garbage, Does not have the effect of recycling, such as the patent authorization announcement number CN202403320U, this design directly dissolves the oil fume in water, causing unnecessary waste of resources

Second, it is necessary to frequently replace the components required for purification, and the cost is high. For example, the authorized announcement number CN202419759A, oil fume! Electric purification and stove integrated equipment, the equipment lacks the replacement of purification components, resulting in high cost and difficult to use for a long time

3. The pollution of the waste oil fume to the pipeline makes the purification effect of the device continuously weakened. For example, the patent authorization announcement number CN102705882A, a kind of oil suction fume used in the kitchen! Purify oil fume and stove 1. The equipment is based on horizontal arrangement, which is easily affected by oil fume pollution, causing functional failure and other adverse effects
