Atomizing disk of high speed centrifugal type atomizer

Abstract

The invention discloses an atomizing disk used for a high-speed centrifugal atomizer. In the atomizing disk, a nozzle disk is positioned on the lower surface of a disk-shaped upper cover and the top surface of a disk-shaped base, and the three parts are fixed through screw bolts. An atomized liquid storage space is formed between the inner walls of the disk-shaped upper cover, the disk-shaped base and the nozzle disk. Cylindrical columns are distributed uniformly and circumferentially in the radial direction on the nozzle disk. A nozzle and a stopper are disposed from the inside to the outside inside each cylindrical column. The atomizing disk has the advantages of simple structure, easy fabrication, and convenient assembly / disassembly of atomizing nozzles. The atomizing disk increases the atomizing distance, reduces the requirement for rotation speed of the atomizing disk, improves the working conditions of the bearing of the driving shaft of the atomizing disk, and reduces the requirements for installation and lubrication of the bearing. The rotation speed of the atomizing disk is lower than 10000 r / min, so that the vibration of the atomizing disk and the motor main shaft is reduced and the service life of the motor is prolonged. Additionally, speed-increasing mechanism is dispensable, thereby reducing the use cost of the atomizer.

Description

technical field [0001] The invention belongs to the field of solid waste incineration treatment, and in particular relates to an atomizing disc of a high-speed centrifugal atomizer, which is a key component of a flue gas purification system for solid waste incineration treatment. Background technique [0002] The high-speed centrifugal atomizer uses a high-speed motor to drive the atomizing disc to rotate at high speed. The high-speed rotating atomizing disc generates a strong centrifugal force, so that the material in the form of suspension or emulsion is sprayed out through the nozzle with a special structure of the atomizing disc. Thus being atomized into droplets with a micron scale. The increase in the surface area of ​​the atomized particles is more conducive to mass transfer and heat transfer or mixing with other media to react. [0003] The existing atomizing disc is cylindrical, with a liquid storage chamber in the middle, and nozzle installation holes are opened a...

AI Technical Summary

Problems solved by technology

The traditional method is to use the gears of the gear box to drive the atomizer, which is expensive to manufacture, and the noise and vibration are large, and the wear is serious.

There are also belt drive, the belt drive is easy to slip under high temperature, resulting in lower and unstable atomizer speed and poor atomization effect

In addition, after a certain period of use, the belt is prone to aging

Since the rotation speed of the atomizing disc reaches 10000r / min, the manufacturing and installation accuracy of the driving shaft bearing of the atomizing disc is very high. The high-speed rotation of the bearing for a long time will generate high heat, resulting in the loss of lubricating grease of the bearing, and the bearing is prone to failure due to operation. oil damage
