Abstract

The invention provides an anti-explosive cylinder system. The anti-explosive cylinder system comprises a cylinder body and a pressure relief device, wherein an accommodating chamber is formed in the cylinder body for accommodating a high pressure substance; the pressure relief device is connected to the cylinder and has a pressure relief state which enables the accommodating chamber to relieve pressure and a sealing state which enables the accommodating chamber to keep the pressure; the pressure relief device can be switched between the pressure relief state and the sealing state repeatedly. When the pressure in the cylinder is too high, the pressure relief device is switched to the pressure relief state to relieve the pressure and when the pressure is relieved, the pressure relief device is then switched to the sealing state to seal so as to relieve the pressure of the cylinder back and forth, and therefore, the problem of cost and time waste due to repeated replacement of an anti-explosive safety film in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of pressure relief equipment, in particular to an explosion-proof steel cylinder system. Background technique [0002] At present, the coal-to-olefins project mainly adopts olefin separation technology. The industrial ethylene sampling outlet is high-pressure low-temperature liquid-phase ethylene, and the samples are sampled using pressure-resistant steel cylinders. Since the critical temperature of ethylene is 9.5°C, the critical pressure is 10.5MPa, and the boiling point at atmospheric pressure is -103.9°C, the ambient temperature difference before and after sampling is large. The sudden increase will easily overpressure the sampling cylinder. Therefore, the requirements for samplers in GB / T 13289-2014 Industrial Ethylene Liquid and Gas Sampling Method: [0003] (1) Select a special sampling cylinder with double valves and adjustable tubes. The volume is 0.1L ~ 1L, and the working pressure is 19.6MPa (2...
