Description
Technical Field
The invention relates to the technical field of vacuumizing, in particular to a field portable sample bottle vacuumizing device.
Background
The gas sampling technology is widely applied to the fields of petroleum, chemical industry, mining, environmental protection, electric power and the like. Because on-site gas analysis is sometimes inconvenient on-line, the gas source is typically sampled, temporarily stored in a sampling vessel, and then taken to analysis instrumentation for analysis. Some are sampling gas from pressure sources such as pressurized pipes and pressurized containers, and some are sampling gas from atmospheric or negative pressure environmental sources. The former is usually provided with a sampling port and enters a sampling container such as a sampling air bag, a sampling bladder, a sampling bottle, an injector and the like under the pressure pushing of a pipeline and the container; the latter typically draws gas into a sampling vessel using a gas sampling pump. The gas source sampling port can be fixed (common for pressure source sampling) or movable (common for environmental source sampling), while the sampling container is usually detachable, convenient to move and recycle.
In the process of connecting the sampling port with the sampling container, because the sampling containers such as the sampling air bag, the sampling bladder, the injector, the sampling bottle and the like are not vacuum, the connected pipelines are not vacuum, and air and gas residues in the previous sampling are left in the sampling containers. In order to ensure the accuracy and safety of sampling, the original residual gas needs to be replaced before the new gas to be sampled is filled, and a vacuum device is needed for the replacement.
However, in the current market, when sampling gas is needed to be used in the field, no equipment capable of directly vacuumizing the sample bottle exists in the field, and the sample bottle is generally required to be vacuumized in a laboratory and then brought to the field for operation. Because the sample bottle is in a negative pressure state after being vacuumized, in a field environment, gas enters the sample bottle in the process of transporting the vacuum sample bottle for gas sampling, the sample is easy to be polluted, and the portable vacuum pumping device for sample bottle sampling can bring much trouble to workers no matter the sample bottle is carried or operated.
