AI Technical Summary
Existing SCR reactors do not facilitate the rapid disassembly and maintenance of the catalyst bed, leading to difficulties in maintenance and replacement.
An SCR pressure detection device was designed, comprising a limiting mechanism and a detection mechanism. The limiting mechanism enables the rapid opening and closing of the sealing door, and the sealing performance is improved by combining it with a sealing gasket. The detection mechanism uses a pneumatically controlled solenoid valve and a pressure transmitter to achieve multi-point pressure detection.
It enables rapid replacement and maintenance of the catalyst layer, improves the sealing performance and pressure testing flexibility of the unit, reduces investment costs, and facilitates on-site commissioning.
