Changsha Roots blower typical use (IX)
- High temperature slag cleaning
The temperature of smelting slag is generally as high as several hundred degrees or even thousands of degrees, and vacuum pumps are usually utilized to suck the slag and cool it with water so that it becomes sandy particles to be separated from the separator, and the gases are discharged into the atmosphere by vacuum pumps. Some aluminum plants, in the carbon shop with a similar method from the roaster to suck unloading high-temperature coke particles.
- Polymer Powder Conveying
Polyethylene and polypropylene powders are commonly conveyed in polymer processes using nitrogen. The purpose of using nitrogen is to prevent the polymer powder from exploding with air and flammable volatile media. In order to reuse the nitrogen, the conveying system is a closed loop and the filtered gas is returned to the blower for recycling.
- Positive and negative pressure combined material conveying
In the material has more than one feeding point and more than one unloading point occasions, usually use the positive pressure and negative pressure combination of conveying methods. The vacuum pump will suck the material into the pipeline and unloading point. Sometimes only one blower is used, both as a vacuum pump for the suction and conveying system and as a blower for the pressure conveying system.
- Pressurized transportation of special gases
Blowers are used in coking plants to pump crude gas to the refining process. Blowers are used as pressurizers in city gas systems to deliver gas from tanks to distant gas points. Blowers are used in the sulfuric acid production process to transfer SO2Gases are sent to the conversion process, blowers are used to transport ethylene gas in the polyvinyl alcohol synthesis process in vinylon plants, etc.
