　　Chengdu Roots Blower FactoryTell you the role of Roots blower in the desulfurization process:

Chengdu Roots Blower Factory tells you that the blower looks similar to the role of an electric fan, but in fact the purpose of using a fan is a mistake. For most air conditioners, the fan is useful. There are many, but the fan is not affected, because it has a very wide range of uses. The range hood at home, YangJi water, vacuum pump, etc. are all when the fan works. For example, the vacuum machine can pump air with Roots blower. Desulfurization refers to fixing the sulfur element in coal into a solid by calcium-based methods to prevent SO2 from being generated during combustion. At present, there are many kinds of desulfurization process: limestone-gypsum method, spray drying method, ammonium phosphate fertilizer method, furnace tail humidification method of calcium injection. In fact, the emergence of rotating fans is very early, and now it has been used in many industrial production. The rotary fan has simple structure and small volume, which is convenient for transportation and maintenance. The rotating fan has a simple and exquisite structure and consists of six parts. So what is the use of a rotating fan? Why is it so widely used?

　　Chengdu Roots Blower FactoryTell you currently the most widely used, the highest frequency of desulfurization technology is limestone-gypsum desulfurization process, accounting for about Japan, Germany, the United States thermal power plant flue gas desulfurization device 90%. Its working principle is: the slurry made of limestone powder and water as the absorption pump into the absorption tower and the flue gas full contact and mixing, the sulfur dioxide in the flue gas and the calcium carbonate and air in the slurry from the lower part of the tower into the oxidation reaction to generate calcium sulfate, calcium sulfate reaches a certain degree of saturation, the crystal forms gypsum dihydrate. The gypsum slurry discharged from the absorption tower is concentrated and dehydrated to make its water content less than 10%, and then sent to the gypsum warehouse by the conveyor for stacking. The desulfurization flue gas passes through the defogging device to remove liquid droplets, is heated by the heat exchanger, and enters the atmosphere through the chimney. Because the absorption slurry in the absorber circulates repeatedly with the flue gas through the circulating pump, the absorbent utilization rate is very high, the calcium-sulfur ratio is low, and the desulfurization efficiency can reach more than 95%.

　　Chengdu Roots Blower Factory: In the limestone-gypsum desulfurization process, the Roots blower acts as an oxidation fan: accelerates the oxidation rate and oxidizes calcium sulfite to calcium sulfate. As the key large-scale equipment in the whole desulfurization operation, the use of the oxidation fan directly affects the investment and operation effect of the whole desulfurization project. What is a vacuum machine is to put some air in the space, so it needs a lot of suction. The role of the Roots blower. First of all, it belongs to a positive displacement pump. The discharge space of the positive displacement pump affects the ship air. The internal structure is different but the principle is Compressed air or air backlog, vacuum suction needs to suck air in the air inlet, space, and discharge through rotating air.

The above is the introduction of Chengdu Roots Blower Factory on Roots Blower. This blower has a large pressure coefficient and can be used in many fields.
