How to solve the problem of solid particles being carried in the exhaust gases, which causes frequent blockages in the heat exchangers?
Optimize process control by regulating the temperature of the hydrogenation reaction, in order to minimize or avoid the formation of silicon particles. When disassembling and assembling the reduction furnace, ensure that the exhaust ports are properly sealed to prevent silicon particles from falling into the exhaust system. A dual filter can be installed on the exhaust manifold.
Reply to 1# jindin312: Install a filter; once clogging is detected, switch to another filter and clean it!
This problem is very simple: the silicon that is formed in the reduction furnace ends up in the exhaust system. A filter must be installed before it reaches the cooler; otherwise, the heat exchanger will often get clogged.
The best approach is to avoid the formation of solid particles
I don’t think there’s a good way to solve this at the moment! ! !
With dual filters in place, the furnace can become clogged during the growth process, which leads to a sharp increase in pressure; this in turn causes the furnace to shut down due to excessive pressure
Installing a filter is not the ultimate solution
This problem is easy to solve. First, a filter needs to be added; however, care must be taken when selecting the appropriate filter. Additionally, it’s important to control the reduction furnace and optimize its operation in order to minimize the formation of uncontrolled silicon.
