Electrostatic dissipation type oil mist separation cylinder

Abstract

The invention relates to the technical field of oil mist separation cylinders, in particular to an electrostatic dissipation type oil mist separation cylinder. The oil mist separation cylinder comprises a shell and a separation cylinder body, wherein the shell is connected with a cover plate, an air inlet is formed in the lower end of the shell, an air outlet is formed in the side wall of the shell, an oil discharging outlet is formed in the bottom of the shell, and the separation cylinder body is installed in the shell. The separation cylinder body comprises an electrostatic dissipation layer, a collision coalescence layer and a particle capture layer, wherein the electrostatic dissipation layer, the collision coalescence layer and the particle capture layer are composed of a first functional material, a second functional material and a third functional material respectively, the surface resistance value of the first functional material of the electrostatic dissipation layer is 106-1011 omega, and the first functional material has an electrostatic dissipation function. By means of the electrostatic dissipation type oil mist separation cylinder, it can be achieved that charges offset each other after charges oil mist particles with charges collide with the electrostatic dissipation layer, the possibility that the like charges of the charged oil mist particles repel is greatly reduced, the coalescence efficiency is improved, and therefore, a better particle capture effect is achieved.

Description

Technical field [0001] The present invention relates to the technical field of oil mist separation cylinders, and more specifically, it relates to static dissipative oil mist separation cylinders. Background technique [0002] The metallurgical, petrochemical, and mechanical industries that use large-scale, heavy-duty, high-speed equipment generally use circulating centralized oil supply devices to provide lubrication to gearboxes, bearings, and sliding shoes, and rely on lubricating oil to bring the heat generated during the operation of the equipment back to the tank . This heat repeatedly heats the lubricating oil to form an oil mist, which also contains carbonized tiny particles. The generation of oil mist and oil fume not only forms a slight positive pressure in the fuel tank, which hinders the oil return process of the system, but arbitrary discharge also seriously pollutes the environment, increases oil loss, greatly increases the concentration of particles below PM2.5 in...

AI Technical Summary

Problems solved by technology

[0005] In our oil mist separation process, the most difficult thing to deal with is the aerosol colloid after oil atomization. Filtration can solve the large oil droplets of 10um level, but the oil mist dispersoid particles with smaller diameters are between 1 nanometer and 1000 nanometers. The substances are easily mixed in the gas and pass through the oil mist separation cylinder together, and if the charged particles of the dispersed substances are of the same polarity, the particles will repel each other due to the same polarity of the charge, which will make the particle capture efficiency low, and the gas mist separation effect will be poor
