1, Overview and purposes; In the gas cylinder of the testing process, in order to prevent the gas cylinder in the residual gas and air mixture, diffusion, which led to pollution of the environment, resulting in excessive combustible gases in the air, affecting the health of staff, must be carried out on the gas cylinder replacement shorting or recycled. The nitrogen gas cylinders designed for replacement devices can fundamentally solve the problem.Second, technical parameters; 1. Whenever the number of cylinders: 1 2. Nitrogen pressure inside the cylinder: 0.6 13MPa 3. Decompression nitrogen pressure: 0.4 0.6MPa 4. Permutation after gas content (V): <2% 5. Equipment Weight: 100Kg 6. Overall dimensions (L × B × H): 2200 × 440 × 15003, process and equipment described in: The device uses a certain pressure nitrogen gas charge will be carried out into the replacement of gas cylinders in the gas, so that the residual cylinder gas and nitrogen mixed, diluted the concentration of gas cylinders can be, and mixed gas discharge shorting or recovery, in order to achieve gas exchange The purpose and effect. This device has a gas sampling point (sampling to facilitate the detection, analysis), a venting valve and a recovery valves for gas venting or recovery (vapor recovery only to high-temperature combustion furnace combustion processing).
