Embodiment
[0022] Such as figure 1 , figure 2 , image 3 As shown, it includes a filter mesh 2, an oil tank 3, and a device pipe body 3. The filter mesh 2 is arranged obliquely inside the pipe body through a slot connection method, which can be easily disassembled and cleaned. The lower end of the filter mesh 2 is equipped with a slope-shaped oil groove 3. It is used to collect oily fumes dripping from the filter mesh 2. The specific structure of the filter mesh 2 is that the filter mesh 2 is mainly made of a polytetrafluoroethylene sheet with a filter hole 7, and the polytetrafluoroethylene sheet is surrounded by a metal outer frame 6, and the metal outer The frame 6 is equipped with a draw-in groove, which is connected with the pipe body draw-in groove on the inner wall of the device tube, so as to facilitate the disassembly, replacement and cleaning of the filter mesh 2 as a whole. The specific preparation method of the polytetrafluoroethylene sheet with the filter hole 7 is to he...

The invention relates to a maintenance-free filtration type oil fume purification device capable of adsorbing and collecting cooking oil fume. The oil fume purification device comprises a pipe body. A filtrating screen sheet is arranged inside the pipe body in an inclined manner. An oil groove is formed in the lower end of the filtrating screen sheet. The oil groove is connected with an oil collecting box. The oil fume purification device has a wide application range, the maintenance-free function of the device can be achieved without the need of replacing parts frequently, procedures are simple, time is saved, and the cost of the oil fume purification is relatively low. The service life is prolonged, properties are stable, the problems that parts need to be replaced frequently, procedures are complicated and time is wasted in the prior art are solved, a maintenance-free filtration type oil fume purification mode is achieved and the oil purification device is easy to popularize and apply.
Description
technical field [0001] The invention relates to the field of oil fume purification, in particular to a maintenance-free filtering oil fume purification device capable of absorbing and collecting cooking oil fumes. Background technique [0002] The rapid development of the catering industry has led to a large amount of cooking fume emission. The fume emitted has great adhesion and condensation, and it is easy to adhere to the filter mesh and the inside of the pipe during the process of being sucked by the range hood, forming a condensate layer. , can form a thicker grease layer in a short period of time, which seriously affects the normal operation of the range hood, and requires regular cleaning and maintenance. At present, my country's oil fume purification technology is mainly based on several physical methods such as electrostatic, adsorption, and filtration, while the traditional electrostatic oil fume removal method needs to clean the dust collecting electrode frequentl...
