Application of Rotary Paddle Switch in Wenchang Waste Incineration Power Generation Project
Recently, Jiwei Rotary Paddle Switches have successfully won the bid in some waste incineration power generation projects. The typical application is Wenchang waste incineration power generation project, which is mainly used for level measurement in reaction tower ash hoppers, dust collectors, lime powder bins, activated carbon bins and fly ash bins.
The client hopes to realize the overflow control and dry protection through the alarm signal output by level switches in different silos of the gas purification systems. The working conditions in gas purification system are more complex due to different media in different silos. For instance, the dust after desulfurization in dust removal system is highly corrosive and the maximum medium temperature is 300℃; and the activated carbon bin requires level switches reach the explosion-proof level above Ex d IIC T4 Gb and the protection grade reaches to IP65.
Spin-11P Rotary Paddle Switch won the bid among peers due to the reason that the spindle is enhanced with a stainless steel protection sleeve to effectively avoid material impact damage, and it is suitable for the measurement of high-density solid particles. Besides, Spin-11P Rotary Paddle Switch has the following advantages:
● Purchased high quality key parts such as motor, micro switch from international market.
● IP65 Ingress Protection rating.
● Dual bearing design, stable operation and long life time in service.
● With gas and dust explosion proof certificates, applicable in a wide range.
● Integrated design of motor and anti-loose mechanical mechanism, easy for maintenance and parts replacement.
● Made of 304/316L stainless steel.
