[0022] Engineering process:

[0023] Container shell 1 is placed on the ground through support seat 2, pressure gauge 3 detects the pressure in container shell 1, when the pressure in container shell 1 is too high, controller controls servo motor 6 to start clockwise to drive ball 7 to rotate a set number of turns, so that air hole 8 is communicated with pressure relief pipe 4, the gas in container shell 1 passes through air hole 8, the gas passing through air hole 8 is released from one-way exhaust valve 5 in one way, to reduce the pressure in container shell 1, while avoiding the external gas into container shell 1;

[0024] The gas released from one-way exhaust valve 5 enters open cover 10, the gas contacts filler layer 12 and activated carbon filter screen 11 in turn, and is released after being filtered by filler layer 12 and activated carbon filter screen 11, to avoid the harm of pressure relief gas to personnel's health, and also to avoid air pollution.

[0025] When the pressure gauge 3 detects that the pressure in the container shell 1 is lower than the dangerous value, the controller controls the servo motor 6 to drive the ball 7 to rotate counterclockwise to reset the set number of turns, the air hole 8 is misaligned with the pressure relief pipe 4, and the ball 7 seals the pressure relief pipe 4.

[0026] In example 1, the gas released from the one-way exhaust valve 5 enters the open cover 10, and the space in the open cover 10 is limited, the released gas impacts the filler layer 12, the gas quickly passes through the filler layer 12, and the treatment effect of the filler layer 12 on the gas is reduced, referring to Figures 3-4 As another preferred embodiment of the utility model, the difference from example 1 is that the open cover 10 is communicated with an expansion mechanism 13, the expansion mechanism 13 comprises two symmetrically arranged fixed pipes 131, both of the two symmetrically arranged fixed pipes 131 are communicated to the open cover 10, a piston plate 132 is slidably connected in each fixed pipe 131, an installation plate 133 is fixedly connected to one end of each fixed pipe 131, a spring 134 is fixedly connected to one side of each installation plate 133, one end of each spring 134 is fixedly connected to the corresponding piston plate 132, a connecting rod 135 is rotatably connected to the opposite side of both piston plates 132, one end of each connecting rod 135 is rotatably connected to a same fixed block 136, the fixed block 136 is connected with a guide rod, a sliding groove is formed in the open cover 10, and one end of the guide rod is slidably connected to the sliding groove.

[0027] The gas released from the one-way exhaust valve 5 impacts the fixed block 136, so that the fixed block 136 moves towards the activated carbon filter screen 11, the fixed block 136 moves stably under the guidance of the guide rod, the fixed block 136 pushes the connecting rod 135 after moving, the connecting rod 135 pushes the piston plate 132, and the volume of the fixed pipe 131 communicated with the open cover 10 is increased after the piston plate 132 moves, so that the internal space of the open cover 10 is increased, the gas released from the one-way exhaust valve 5 is buffered, the flow speed of the gas in the open cover 10 is reduced, the contact time of the gas and the filler layer 12 is prolonged, and the treatment effect of the filler layer 12 on the gas is improved.
