High-pressure electrostatic oil removal device

Abstract

The invention relates to the technical field of VOC waste gas treatment, and especially relates to a high-pressure electrostatic oil removal device. The high-pressure electrostatic oil removal deviceis used for removing oily particulate matters in dry waste gases, and comprises an exhaust pipe with an air inlet and an air outlet respectively on both end faces; and the exhaust pipe is provided with an electrostatic wire which is connected to a power supply through a step-up transformer to generate a high-voltage electrostatic field of 40,000 to 75,000 volts in the exhaust pipe. The high-pressure electrostatic oil removal device provided by the invention can be used for carrying out adsorption treatment on the VOC and the dust in the dry waste gas through the high-voltage electrostatic field of 40,000 to 75,000 volts, and has the advantages of being good in treatment effect and easy to clean.

Description

technical field [0001] The invention relates to the technical field of VOC waste gas treatment, in particular to a high-voltage electrostatic degreasing device. Background technique [0002] Polyolefin plastics have a wide range of applications, have good physical, chemical and mechanical properties, good toughness, flexibility and cushioning properties, and have properties such as electrical insulation and heat insulation. They are widely used in packaging, chemical industry, construction and other fields. Polyolefin foams are widely used and one of the first foams to be successfully produced. At present, the preparation of cross-linked polyolefin mainly involves kneading and granulating polyolefin raw materials and various additives, adding them into an extruder for plasticization, and obtaining a polyolefin master sheet with all components mixed uniformly, and then passing through a foaming furnace Foaming is performed. [0003] Since a certain amount of flue gas and or...

Problems solved by technology

[0008] Secondly, it can be seen from the accompanying drawings of this application that in order to tighten the metal electrostatic wire, end caps are respectively provided at both ends of the electrostatic outer tube, so that the air inlet and air outlet can only be arranged on the side wall of the electrostatic outer tube

This will cause the gas to move obliquely upwards under the action of inertia after entering the electrostatic outer tube from the air inlet on the side wall, not only away from the inner wall of the electrostatic outer tube used for adsorption, resulting in poor adsorption effect, but also easy to pollute the electrostatic wire. And it is possible to blow the oil particles that have adhered to the tube wall, thereby taking them out of the electrostatic outer tube, resulting in poor degreasing effect, and at the same time, it is difficult for the gas to escape from the air outlet

[0009] In addition, after the electrostatic outer tube in this application has been used for a long time, it is difficult to clean the oil particles that are attached to the inner wall of the electrostatic outer tube and are difficult to slide off, and its degreasing ability will decrease with the increase of attachments, and the service life is short
