Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification, and in particular to an oil fume purification device that is convenient for application in multiple scenarios. Background Art

[0002] At present, electrostatic oil fume purification devices are widely used in industrial oil fume purification places. Its structure includes: a purification box, one end of the purification box is provided with an air inlet, the other end of the purification box is provided with an air outlet, and a high-voltage electrostatic field is provided in the purification box between the air inlet and the air outlet. The structure of the traditional high-voltage electrostatic field includes: a plurality of matrix-arranged unit electric fields arranged along the flow direction of the oil fume, each unit electric field includes: a mounting frame, and a corona area and a collection area are sequentially arranged in the mounting frame along the flow direction of the oil fume. The corona area makes the oil fume particles in the air carry positive or negative charges, and the oil fume particles with positive or negative charges enter the collection area and are collected by the collection area. When working, the air containing oil fume particles enters the purification box from the air inlet, and the air containing oil fume particles entering the purification box enters each unit electric field in turn, and passes through the corona area and the collection area of ​​each electric field in turn, so that the oil fume particles in the air are removed, and the air without oil fume particles is discharged from the air outlet.

[0003] In catering places, the characteristics of oil fumes produced by cooking different cuisines are also different, such as home cooking, Western food, Sichuan and Hunan cuisine (more oil, chili, and stir-frying, resulting in heavy oil fume and strong taste), rice and flour food (less oil fume and more water vapor), hot pot (more oil fume and water vapor), barbecue (more particulate matter and strong taste), etc. Different specifications of oil fume purification equipment need to be used for different cuisines, which has limitations.

[0004] The main parameters that determine the purification efficiency of electrostatic oil fume purification equipment are the charge intensity of the corona zone and the electric field intensity of the adsorption zone. The traditional purification module limits the corona intensity of the corona zone due to structural reasons, thereby limiting the purification efficiency. At the same time, the electric field of the traditional electrostatic oil fume purification device is directly inserted into the box by sliding. Since the electric field is heavy, it is laborious to pull it out. In the process of purifying the oil fume, the adsorbed oil fume gathers at the junction of the electric field and the box, which is easily contaminated by the oil fume, resulting in a short cleaning cycle of the electric field. In addition, a large amount of oil fume remains on the surface of the electric field, which is not easy to clean, resulting in low work efficiency and high operating costs.

[0005] Therefore, there is a need for a fume purification device that can adapt to different cooking scenarios of different cuisines through the selection and combination of electric fields according to usage requirements, purify different oil fumes, improve the oil fume purification efficiency and usage compatibility, improve the ability to resist oil fume pollution, increase the cleaning cycle, and is easy to clean.

[0034] In catering places, the characteristics of oil fumes produced by cooking different cuisines are also different, such as home cooking, Western food, Sichuan and Hunan cuisine (more oil, chili, and stir-frying, resulting in heavy oil fume and strong taste), rice and flour food (less oil fume and more water vapor), hot pot (more oil fume and water vapor), barbecue (more particulate matter and strong taste), etc. Different specifications of oil fume purification equipment need to be used for different cuisines, which has limitations.

The corona module 5 and the adsorption module 6 move on the rolling device 8 to enter or leave the box body 1, or the corona module 5. and the adsorption module 6 are provided with a rolling device 8 for entering or leaving the box body 1; since the electric field in the corona module 5 and the electric field in the adsorption module 6 are heavy, it is more laborious to install and replace the electric field.
