Summary of the invention
The objective of the invention is does not have function of cleaning and the deficiency of measuring water percentage and proposes a kind of multifunctional gas sampling system and the method for sampling at gas sampling assembly in the prior art.
The structure of described multifunctional gas sampling system connects first transfer valve for the air intake opening at aspiration pump, and the gas outlet of aspiration pump connects second transfer valve, and second transfer valve and exhausr port are connected; Between first transfer valve and second transfer valve, connect overvoltage protection valve and gas and collect mouthful, on first transfer valve and the relative interface of overvoltage protection valve 8 interfaces, connect the gas thermometer, flow totalizer of series connection successively, except that water pipe, dust removing tube and air intake opening; Removing connection the 3rd transfer valve between water pipe and dust removing tube junction and the aspiration pump air intake opening.
Described the 3rd transfer valve is a two-way valve.
Described first transfer valve and second transfer valve are T-valve.
A kind of method of sampling of multifunctional gas sampling system is characterized in that, described gas sampling comprises that step is as follows:
The first, the road of bleeding is in advance carried out dust removal process to gas production pipe with desiring the gas production body, desires the gas production body and enters the dust removing tube dedusting from air intake opening, directly enters aspiration pump by the 3rd transfer valve, is guided to exhausr port through second transfer valve again and discharges gas;
The second, the gas production bag cleans, and the gas in the gas production bag enters aspiration pump through first transfer valve earlier, and is guided to the exhausr port discharge by second transfer valve;
The 3rd, gather gas, desire the gas production body and enter the gas production system from air intake opening, through the dust removing tube dedusting, dewater through removing water pipe, through the flow totalizer metered flow, and, enter aspiration pump by first transfer valve through behind the gas thermometer metering temperature, import in the sampler bag by second transfer valve again.
Described overvoltage protection valve can be exitted when the collection gaseous tension is too high and be protected the gas production bag.
Described aspiration pump can be selected the membrane type aspiration pump of flow 1L/min～20L/min for use.
The invention has the beneficial effects as follows that the application sample system can convert dedusting, the dehydration of needs analysis dry gas to and charge in the special-purpose gas container.It is significantly different that this gas production system and the current gas production system that has had have, and key reaction is in the following aspects:
1. three transfer valves of having packed into can conveniently be finished the cleaning of gas production bag, guarantee that the gas of sampling can reach very high purity;
2. installed dust removing tube before the aspiration pump additional and removed water pipe, the gas that can make collection is dust-laden and water not, guarantees that gas is in stable status;
3. after removing water pipe gas flow and thermometric device are arranged, can accurately measure the volume total amount and the quality total amount of dry gas;
4. before removing water pipe bypass is arranged, it is for convenience detach to remove water pipe itself, guarantees that the result who weighs before and after the suction hose suction can measure water absorbing capacity.The hygroscopic agent that removes in the water pipe is convenient for changing, and can satisfy the needs under the different measuring condition.
