High-speed-rotation atomizer with vibration protection function

Abstract

The invention discloses a high-speed-rotation atomizer with the vibration protection function. The high-speed-rotation atomizer comprises an atomizer body, a supporting flange and a controller, wherein a vibration measurement device is installed at the top of the supporting flange; the supporting flange comprises an upper supporting flange body and a lower supporting flange, a damping gasket is installed between the upper supporting flange body and the lower supporting flange body, an atomization wheel is installed at the bottom of the atomizer body through a retracting nut, and multiple windage resistance baffles are installed at the bottom of the atomization wheel through a rotating mechanism in the circumferential direction; the rotating mechanism comprises baffle bases, baffle supportsand stretchable rods, the baffle bases are fixed at the bottom of the atomization wheel through small base bolts, the bottom ends of the baffle supports are fixed on the side walls of the windage resistance baffles, and the top ends of the baffle supports are rotationally installed on the baffle bases through rotating shaft pin bolts. According to the high-speed-rotation atomizer with the vibration protection function, the braking time of the atomization wheel can be greatly shortened, and more-serious damage of acute vibration to the atomizer is reduced.

Description

technical field [0001] The invention belongs to the field of liquid process forming and industrial atomization drying, and in particular relates to a high-speed rotary atomizer with vibration protection function. Background technique [0002] With the improvement of people's living standards, the air quality has attracted much attention from the society. The country has started the "ultra-low emission" policy in 2014. The policy requires that coal-fired boilers in thermal power plants adopt efficient collaborative removal integrated system technology for multiple pollutants in the process of power generation operation and terminal treatment to reduce air pollution. In terms of desulfurization, the current main desulfurization methods include dry desulfurization, semi-dry desulfurization, and wet desulfurization. [0003] Among them, taking the semi-dry method as an example, the most common is the SDA rotary spray drying method. This method mainly uses the centrifugal force ...

Problems solved by technology

[0004] As the core equipment of desulfurization by rotary spray drying method, high-speed rotary atomizer directly determines important indicators such as desulfurization efficiency and maintenance cost. The existing atomized slurry is mostly calcium hydroxide slurry, and some of them are in solid state. The atomizer nozzle Susceptible to wear, corrosion, and clogging. After long-term use, it will cause the atomization wheel to vibrate out of balance. In the case of high-speed rotation, it will even cause the atomizer to vibrate violently, which will eventually reduce the damage of the atomizer and even cause serious safety accidents. The existing fog Among the atomizer damping gaskets, most of them are plane damping gaskets, which only consider the longitudinal pressure vibration reduction, but do not consider the horizontal shear force generated by the atomizer during high-speed rotation.

At the same time, in the existing atomizing wheel, after the power supply is cut off in an unexpected situation, the atomizing wheel will pass through a long period of time under the action of inertia to completely stop, which brings inconvenience to emergency braking and normal maintenance. little trouble
