Abstract
The utility model relates to a gas mixing device for different concentration flue gas are gathered, including gas mixing bucket, bung, a plurality of gas circuits, filter, flowmeter, bung and gas mixing bucket sealing connection, be equipped with the interface of external aspiration pump on the bung and lead to a plurality of suction nozzle and the play gas nozzle of sampling gas, connect a gas circuit on every suction nozzle, the direction that goes up along gas admission gas mixing bucket on every gas circuit has connected gradually filter and flowmeter. The collection and mixing of the gas are convenient, the multi-path collection and mixing of the sample can be realized simultaneously, and the filter is arranged, so that large particles of a pollution source in a flue can be filtered in time; the flow rate of gas collection can be adjusted, so that the gas is uniformly mixed; the switch is free, when wanting to extract gas and do the analysis, can open the gas outlet nozzle switch, if only gather and store, do not extract the gas after the mixture, can close the gas outlet nozzle switch.
Description
Technical Field
The utility model relates to a gaseous appearance technical field that mixes specifically is a mix gas device that is used for different concentration flue gas to gather.
Background
At present, if pollution sources with different concentrations are collected from a flue, a plurality of containers are used for collecting gases with different flue heights, and then the gases are mixed and pumped out for research. In the collection process, the flow and the flow velocity of the collected gas cannot be effectively controlled, so that the gas collected at the opening of each flue cannot be uniformly mixed, and the experimental error is greatly increased. Generally, the use of such sampling methods to collect the contaminant source gas for which the data to be analyzed is required increases the sampling time and is inconvenient for gas collection and access.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a gas mixing device for different concentration flue gas are gathered solves the unable simultaneous acquisition of different concentration flue gas of current collection, can not flow control, velocity of flow scheduling problem in the acquisition process.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a mix gas device for different concentration flue gas are gathered includes gas mixing barrel, bung, a plurality of gas circuits, filter, flowmeter, the bung with mix gas barrel sealing connection, be equipped with the interface of external aspiration pump on the bung and lead to a plurality of nozzles and the play gas nozzle of sampling gas, connect a gas circuit on every nozzle, the direction that goes up along gas admission gas mixing barrel on every gas circuit has connected gradually filter and flowmeter.
Preferably, a sealing ring is arranged on the barrel cover.
Preferably, the barrel cover is connected with the gas mixing barrel through a lock catch.
Preferably, the flowmeter is fixed on one side of the gas mixing barrel through a support plate.
Preferably, the air outlet nozzle is provided with a switch.
Compared with the prior art, the beneficial effects of the utility model are that:
the collection and mixing of the gas are convenient, the multi-path collection and mixing of the sample can be realized simultaneously, and the filter is arranged, so that large particles of a pollution source in a flue can be filtered in time; the flow rate of gas collection can be adjusted, so that the gas is uniformly mixed; the switch is free, when wanting to extract gas and do the analysis, can open the gas outlet nozzle switch, if only gather and store, do not extract the gas after the mixture, can close the gas outlet nozzle switch.

Examples
Please refer to fig. 1-2, the utility model provides a mix gas device for different concentration flue gas are gathered, including mixing gas bucket 1, bung 2, six gas circuits 3, filter 4, flowmeter 5, bung 2 with mix gas bucket 1 sealing connection, be equipped with the interface 6 of external aspiration pump and lead to six suction nozzle 7 and four air outlet nozzle 8 of sampling gas on the bung 2, connect a gas circuit 3 on every suction nozzle 7, the orientation that mixes gas bucket 1 along gas admission on every gas circuit 3 has connected gradually filter 4 and flowmeter 5. In practical application, for example to the chimney of co-altitude not, only need connect pipeline and the opium pipe of co-altitude not on suction nozzle 7 and can carry out gaseous collection, can be through gathering six ways of gas, and each way of gas all can filter the big particulate matter in the flue gas through filter 4, and flowmeter 5 can control the velocity of flow and the flow of each way of flue gas.
In order to increase the air tightness between the barrel cover 2 and the air mixing barrel 1, as a preferred embodiment of the present embodiment, a sealing ring (not shown in the figure) is disposed on the barrel cover 2.
In order to facilitate the opening of the gas mixing barrel 1 for cleaning, the gas mixing barrel 1 of the embodiment is provided with a barrel cover 2 which can be opened and closed, and as a preferred embodiment of the embodiment, the barrel cover 2 is connected with the gas mixing barrel 1 through a lock catch 9.
In order to fix six flow meters 5, as a preferred embodiment of the present embodiment, the flow meters 5 are fixed to the side of the gas mixing barrel 1 by a support plate 10. The support plate 10 has an arc-shaped portion 101 fixedly connected to the air-mixing tub 1 and a support portion 102 for fixing the flow meter 5.
In order to facilitate the extraction of the mixed gas and satisfy the function of only preserving the mixed gas, as a preferred embodiment of the present embodiment, the gas outlet nozzle 8 is provided with a switch 81.
