Embodiment Construction

[0025] The invention is not limited to the embodiments set forth herein. Rather, these embodiments are disclosed so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0026] The purpose of the following examples is suitable for illustrating the present invention, and the instruments used, detection methods, etc. are not intended to limit the scope of the present invention.

[0027] The atomization corona plasma flue gas purification technology is to maintain the electric atomization wet state with a small amount of water in the discharge electrode, and the atomized water droplets impact the collecting plate and form a thin and uniform water film on the surface of the plate. After the dripping water is separated from the oily dirt, the pump returns the electrodes for recycling.

[0028] In accompanying drawing 1, when work starts, high voltage power supply 3, induced draft fan 6 are opened. Form ...

Abstract

The invention relates to an atomizing corona plasma flue gas purifying device, belonging to a technical field of treating gaseous pollutants. The current purifying oil fume can not completely satisfy the requirements for purifying the oil fume of catering trade. The invention consists of a discharging electrode, a collecting electrode and a high voltage power supply, wherein, the discharging electrode (9) is connected with a negative high voltage power supply (3) through a high voltage wire (15), the collecting electrode (10) is connected to the ground through a wire (16), and an uneven strong electric field is formed between the collecting electrode and the discharging electrode. The device of the invention is characterized in that a lower water-sealing box (4), a spraying upper water box (5) and a nozzle(8) are also arranged, wherein, the lower water-sealing box is connected with a pump (14), the pump is connected with the spraying upper water box (5) through a water pipe (13), the bottom of the spraying upper water box is connected with the nozzle (8), the lower part of the nozzle is connected with the discharging electrode (9); the lower water-sealing box (4) and the spraying upper water box (5) are reserved an overflow opening respectively which is connected with an overflowing pipe (12). The atomizing corona plasma flue gas purifying device can remove oil gas pollution under normal temperature and normal voltage, thus improving the operating circle of the device and reducing maintaining expense.

Description

technical field [0001] The invention relates to a purification device for removing oily fume, which is suitable for removing oily fume and other pollutants in waste gas discharged from catering service industry under normal temperature and pressure, and belongs to the technical field of gaseous pollutant treatment. Background technique [0002] With the development of my country's tertiary industry and the acceleration of urbanization, the proportion of catering service industry in urban economic development is increasing. The rapid development of the catering industry has prospered the urban economy and promoted urban development, but it has also brought serious pollution to the environment. [0003] The existence state of soot includes both suspended particulate matter (TSP) and gaseous organic matter. The total number of pollutants can reach more than 200, mainly including unsaturated hydrocarbons, saturated hydrocarbons, aldehydes, fatty acids, aromatics, sulfur-contain...
