Determine the vacuum system according to the nature of the gas source
The design calculation of the general vacuum system is based on the total gas release Q, and according to the characteristics of the metallurgical process, the nature of the gas source should also be used as the design basis. That is to say, when designing, the quality and quantity of the gas source must be equal to determine the design plan.
In the vacuum smelting process, the significant characteristics of the gas source are the high temperature of the gas and the large amount of dust, as well as the composition of oxygen and hydrogen, and sometimes a large amount of corrosive or toxic gases. Therefore, in some systems, there are usually dust collectors, filters, chemical spelling, and low frustration, and sometimes the pipes need water cooling.
For some corrosive gases, such as sponge sponge process, hydrogen chloride is released, and the dust corrodes the mechanical pump oil and pump body parts, which makes the pump oil have to be changed frequently. According to process requirements, it is better to use a roots pump and a water ring pump to form a vacuum system.
There is also the problem of discharging water vapor. For example, the vacuum system starts to evacuate from the atmosphere and starts to deflate at 1 ~ 10-1Torr, while at 10-1 ~ 10-2Torr, the surface is mainly deflated by water vapor in the air. Gas ballast pumps can partially solve this problem. In the ultra-high vacuum system, there is more hydrogen in the residual gas, and a zirconium aluminum suction pump can also be selected.
Choosing the proper extraction equipment with different gas source properties can make the role of the vacuum system fully play.
