Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of catering oil fume purification, and in particular to a catering oil fume monitoring and purifying device. BACKGROUND

[0002] In the field of catering oil fume purification, the pre-filtering device as a primary purification unit directly affects the load of subsequent treatment equipment and the overall purification efficiency. The traditional pre-filtering device usually adopts a mechanical interception structure (such as a metal filter screen, filter cotton, etc.) or a single inertial collision design, which has the following technical defects:

[0003] 1. Insufficient filtration efficiency: The traditional mechanical filter screen has limited interception efficiency for large particle oil droplets (> 10 μm) suspended in high-temperature oil fume, especially in the working condition of high oil mist fluidity and large particle dispersion, small oil droplets can easily penetrate the filter screen into the rear-end system, resulting in increased load of the subsequent electric field module and washing unit.

[0004] 2. High maintenance cost: The mechanical filter screen or filter cotton is easily clogged by oil stains, which needs to be frequently disassembled, cleaned or replaced, which is complicated and increases downtime, and it is difficult to meet the continuous operation demand of the catering industry.

[0005] 3. Lack of collaborative cooling mechanism: The traditional filtering device does not integrate active cooling function, and when high-temperature oil fume (usually > 80℃) directly enters the subsequent treatment unit, oil mist particles are difficult to condense and liquefy due to high temperature, resulting in a significant decrease in the removal rate of small particle oil droplets (≤ 5 μm) and volatile organic compounds (VOCs).

Therefore, there is an urgent need for a pre-filtering device that can realize active cooling of oil fume, efficient interception of large particle oil droplets and automatic recovery of oil stains through structural optimization.
