Cylinder-type pressurization and pressure release device and pressurization and pressure release method

Abstract

The invention relates to a sub-cylinder-barrel type pressurization and pressure relief device and a pressurization and pressure relief method. The pressurization and pressure relief device comprises a sub-cylinder-barrel sealing device and pneumatic opening mechanisms. The sub-cylinder-barrel sealing device comprises an upper cylinder barrel, a lower cylinder barrel and an upper cover. The lower cylinder barrel is in sliding connection with the upper cylinder barrel, and when the lower cylinder barrel slides to the uppermost end, the lower cylinder barrel closes discharging ports, and the upper cylinder barrel is sealed; when the lower cylinder barrel slides to the lowermost end, the discharging ports are totally opened, and the pressurization and pressure relief device discharges steam and materials. The pneumatic opening mechanisms are used for driving the lower cylinder barrel to slide in the vertical direction. Multi-direction discharging is adopted, and the exhausting and discharging area is increased; large-caliber air inlet valves and large-caliber air exhausting valves are arranged and used for rapidly charging and discharging air cylinders, and meanwhile the air exhausting caliber and the opening speed are increased.

Description

technical field [0001] The invention relates to a cylinder-type pressure relief device and a pressure relief method thereof, which can be applied to a large-scale pressure relief device for organic matter treatment, and belongs to the field of organic matter treatment. Background technique [0002] The main bottleneck of the venting and pressure-releasing speed of large-scale container devices is the size of the venting cross-sectional area. In the traditional venting valve structure, increasing the diameter and increasing the opening speed are contradictory. Therefore, the common problems are that the venting speed is slow and the processing efficiency is low. The problem. Although the cage-type ejection device increases the air release diameter and pressure release speed, but the load is large, the structure is complex, the packing is difficult, and the sealing part is not protected, the pressure release efficiency is low, the sealing ring is seriously damaged, and the rel...

AI Technical Summary

Problems solved by technology

It is difficult to increase the effective cross-sectional area. Due to the limitation of the effective cross-sectional area of ​​the vent, it is also difficult to increase the pressure relief speed of the pressurization and pressure relief device, resulting in the failure of the organic matter treatment to achieve the ideal bursting effect.
