Horizontal rotary multi-disc atomization device

Abstract

The invention discloses a horizontal rotary multi-disc atomization device. The device comprises a barrel, a rotary shaft arranged in the barrel and a power device, wherein the rotary shaft is transversely arranged, an air inlet and an air outlet are formed in the barrel, and a liquid outlet is formed in the lower end of the barrel; the rotary shaft is a hollow rotary shaft, and the rotary shaft istransversely arranged; and the power device is in rigid connection with the rotating shaft, the rotating shaft is sleeved with a rotating disc device, and the rotating shaft is provided with an opening. The horizontal rotary multi-disc atomization device is compact in structure and small in occupied space, tail gas is purified through a super-gravity device, the gas-liquid mixing capacity is enhanced, mass transfer is enhanced, and the purification capacity is excellent; and the rotating disc type supergravity device is adopted, the tail gas purifying capacity is excellent, PM particles in tail gas are thrown to the inner wall of the device by centrifugal force after absorbing moisture and are discharged from the liquid outlet to be removed after sliding down, the problem of particle blockage does not exist, and mounting, dismounting and cleaning are convenient.

Description

Technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a horizontal rotating multi-disk atomization device. Background technique [0002] China's ship ownership has accounted for the fourth place in the world, but the pollution of marine diesel engines has already accounted for about 20% of the urban pollution sources in the Yangtze River Delta and the Pearl River Delta. Therefore, the emission control of marine diesel engines has important environmental protection significance and extensive market demand. . [0003] However, conventional diesel exhaust gas purification methods, such as particulate matter trap (DPF), wet scrubbing, oxidation catalyst technology, low temperature plasma technology, electrostatic capture technology, cyclone separation technology, selective catalytic reduction (SCR), and other technologies, exist The material needs to be replaced, the catalyst is prone to failure, and the cost is hig...

AI Technical Summary

Problems solved by technology

However, when this method is applied to marine diesel engine exhaust gas purification devices, many problems will arise; the reason for these problems is that the fuel used by marine diesel engines is ordinary diesel oil or fuel oil, especially some seagoing ships use distillate fuel oil or residual fuel Oil is the heaviest part of crude oil after distillation. The sulfur content of these oils is about several hundred times that of vehicle diesel, and other impurities are much higher than that of vehicle diesel.

This has caused not only the above-mentioned gaseous and solid pollutants to exist in the exhaust of marine diesel engines, but also contains a large number of unburned heavy oil droplets, carbonized, sulfurized particles, and even many highly viscous asphalt-like substances. After the material enters the rotating packed bed rotor, it will quickly deposit in the porous media packing within 2 to 3 months, forming a blockage that is extremely difficult to clean, resulting in the failure of the rotating packed bed
