Abstract

The invention relates to the technical field of gas packaging containers, in particular to a device and a method for discharging solid particles in a gas cylinder. Through placing the bottleneck of gas cylinder on discharge device's shell upside down, let in the conveying gas to the intake pipe, in conveying gas can spiral entering gas cylinder behind cavity and spiral guiding gutter in proper order, disturbance solid particle in the gas cylinder, along with the inclined plane entry of the discharging pipe of slope, prevent that solid particle from bridging in the discharging pipe to carry the solid particle in the gas cylinder through the discharging pipe more smoothly and collect in the container. Therefore, the technical scheme can rapidly discharge the solid particles in the gas cylinder, prevent the bridging phenomenon of the solid particles in the discharge process, and improve the working efficiency.

Description

Device and method for discharging solid particles in gas cylinder Technical Field The invention relates to the technical field of gas packaging containers, in particular to a device and a method for discharging solid particles in a gas cylinder. Background Various gases (such as nitrogen oxides, hydrogen sulfide, ammonia, volatile organic compounds and the like) can be adsorbed by adsorptive solid particles (such as TiFe alloy, molecular sieve and the like), the solid particles with adsorption function are often filled in a pressure vessel with a structure similar to a gas cylinder with a large belly and a small belly, so that the gas can be adsorbed or desorbed in a fixed space under a certain pressure, and the solid particles with adsorption function contain various metals, wherein the solid particles possibly contain heavy metals such as lead, mercury, cadmium, chromium, arsenic and nickel, noble metals such as platinum, palladium and rhodium, rare earth metals such as scandium, yttrium, lanthanum, cerium, praseodymium and promethium and the like, and similar solid particles containing the elements have recovery values after being filled in the gas cylinder. In addition to recovering solid particles containing recovery value, the gas cylinders which are often adsorbed and re-desorbed are subjected to fatigue load and need to be inspected periodically, and under the condition that the gas cylinder technology with material inspection is not adopted, the solid particles in the gas cylinders are also required to be discharged so as to finish the periodic inspection of the gas cylinders. The structural feature of gas cylinder, except that skin tripe is big, still has the mouth little, and the big mouthful small structure of tripe has filled under the condition of solid particle, and solid particle wherein can bridge if direct outwards fall, obstructs the continuation outflow of granule, reduces work efficiency. If the vent pipe is inserted into the mouth of the gas cylinder, solid particles are carried and removed by using gas, the problem that the solid particles can bridge still exists, and because the inserted gas inlet pipe has a certain diameter, the passage through which the solid particles at the mouth of the gas cylinder pass is reduced in practice, and the solid particles can bridge more easily. Therefore, there is a need to provide a device and a method for discharging solid particles in a gas cylinder to solve the above technical problems.
