AI Technical Summary
The pressure relief efficiency of existing anaerobic fermenters is uneven, which can easily damage the shell.
A pressure balancing device was designed, comprising a sealing retaining ring, a sealing slide plate, a sealing slide cylinder, a supporting protrusion, and a supporting spring. Through the combined use of the first air inlet pipe and the pressure relief pipe, uniform pressure relief is achieved inside the fermenter.
This achieves uniform pressure relief inside the fermenter, avoids damage to the shell, and improves pressure relief efficiency and stability.
