Fume purification system and working method thereof

Abstract

The invention relates to a fume purification system and a working method thereof. A purification host of the fume purification system comprises a closed shell, wherein a partition board is arranged in the shell; a gap is formed between the top of the partition board and the inner wall of the shell, and the other parts of the partition board are in tight coupling with the inner wall of the shell; a plurality of metal tubes are alternately and vertically distributed on two sides of the partition board in the shell; a metal rib is arranged on the central axis in each metal tube, and gaps formed between middle upper parts or the adjacent tops of the every two adjacent metal tubes, between the partition board and the middle upper parts or the adjacent tops of the every two adjacent metal tubes and between the inner wall of the shell and the middle upper parts or the adjacent tops of the every two adjacent metal tubes are closed; a space is formed between the bottom of each metal tube and the inner wall of the bottom of the shell and is divided into a first buffer region and a third buffer region by the partition board; a space is formed between the top of each metal tube and the inner wall of the top of the shell to form a second buffer region; an air inlet and an air outlet of the shell are formed close to the middles or the middle upper parts of the metal tubes located at the front and rear ends.

Description

technical field [0001] The invention relates to an oil fume purification system and a working method thereof, which are applied to printing and dyeing factories (especially the exhaust gas of printing and dyeing setting machines), restaurants and other occasions where the exhaust gas contains oil fumes, plasticizers or other organic compounds. Background technique [0002] The working principle of the electrostatic oil fume purifier is to use a high-voltage electrostatic field to ionize the gas between the electrodes to charge the fine dust and oil mist colloidal particles, so that they can adhere to the plate electrodes to achieve efficient oil fume purification. the goal of. [0003] The dual-zone plate-line electric field in the electrostatic fume purifier includes: an ionization zone composed of a line electric field and an adsorption zone (also called a collection zone) composed of a plate electric field, that is, the ionization zone is composed of several plates connec...

Problems solved by technology

The disadvantage is that the gaps between the positive and negative plates that constitute the plate electric field are often small, and dirt is easy to accumulate on the positive and negative plates, resulting in a short circuit between the electric fields of the plates, resulting in the failure of the collection electric field and the failure to collect oil. It needs to be disassembled and cleaned regularly, and ultrasonic cleaning is generally used, which is time-consuming, laborious and costly

Its disadvantage is that in actual use, the front end of the metal rib 10 cannot always be on the central axis of the cylinder. Once there is a deviation, the front end of the metal rib 10 will accelerate toward the cylinder due to the effect of the electric field force. The inner wall of the body is close, which eventually leads to direct discharge between the front end of the metal rib 10 and the inner wall of the tube 13, which cannot ionize the oil fume particles, thereby affecting the oil fume purification effect

Secondly, because most of the tip discharge occurs at the front end of each metal rib 10 (due to its thicker diameter), the ionization ratio of oil fume particles is low, resulting in a low oil fume purification rate
