BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 A schematic diagram of a systemic airflow balancing and improved processing device; DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0021] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0022] Example 1

[0023] In this embodiment, a systemic airflow balance and improved processing device is proposed, see Figure 1 The systemic airflow balance and improvement treatment device includes a purge valve, a stop valve, a one-way valve, a membrane filter, an air pump, a reflux valve, a pressure gauge, a cooler, and a flow valve.

[0024] like Figure 1 As shown, the purge valve and the stop valve are connected to the one-way valve via a three-way pipeline.

[0025] The one-way valve is connected to the membrane filter via a pipeline.

[0026] The membrane filter is connected to the air pump via a pipeline.

[0027] The air pump is connected to the cooler via a pipeline, wherein a branch is provided in the connecting pipeline between the air pump and the cooler, and a reflux valve is provided at the end of the branch.

[0028] It should be added that a pressure gauge is also provided in the connecting pipeline between the air pump and the cooler.

[0029] The cooler is connected to the flow valve via a pipeline, and the flow valve is connected to the analysis equipment via a pipeline.

[0030] In an embodiment, the systemic airflow balancing and improved processing device has two operating modes:

[0031] First, the sample gas treatment mode;

[0032] Please Figure 1 For reference, the sample gas enters the pipeline through the stop valve, enters the membrane filter through the one-way valve to filter particles larger than 1μm, and then is pressurized to more than 5psi by the air pump, cooled by the cooler and the condensed water is removed, and then adjusted to the set flow rate by the flow valve to enter the analysis equipment.

[0033] It is further explained that after the analytical equipment collects the required amount of gas, the excess sampling waste gas in the pipeline is discharged into the safety pipeline through the reflux valve.

[0034] Second, pipeline cleaning mode:

[0035] Please retry Figure 1 For reference, nitrogen enters the pipeline from the purge valve, passes through the one-way valve, membrane filter, air pump, reflux valve, cooler, flow valve and pipelines used to connect corresponding devices, guiding the residual sample gas in the device to be discharged to prevent the residual sample gas from contaminating the subsequent sample gas.

[0036] The following additional explanations are required for this embodiment:

[0037] First, when the sample gas is processed, the stop valve and the purge valve should be in a free-flowing state.

[0038] Second, when cleaning the pipeline, the stop valve and the purge valve should be in a unobstructed state.

[0039] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
