Abstract
The utility model discloses a gas flow detection device used in a flue gas discharge continuous monitoring system adopting the extraction method. The gas flow detection device comprises a rotameter, wherein a slide track and a slide block are arranged on the side surface of the rotameter; and an induction device is arranged on the slide block. In the utility model, as the induction device is fixed on the rotameter and close to a set alarm flow graduation line, when a floater in the rotameter floats at the graduation, the induction device is triggered to alarm. Therefore, the early warning of failures can be effectively conducted.
Description
Technical field
The utility model relates to a kind of gas flow pick-up unit that is used for the extraction method flue gas discharge continuous monitoring system, especially comprises the gas flow pick-up unit that is used for the extraction method flue gas discharge continuous monitoring system of spinner-type flowmeter.
Background technology
Flue gas discharge continuous monitoring system is the instrument that the stationary pollution source discharged flue gas is carried out real time on-line monitoring.The monitoring project mainly contain gaseous contaminant (
,
Deng) concentration, particle concentration, fume emission parameter etc.Wherein adopt the flue gas discharge continuous monitoring system of extraction method to occupy the majority on market, for the extraction method flue gas discharge continuous monitoring system, stable flow rate is the prerequisite that instrument is measured.When low discharge appears in instrument, not only can influence the accuracy of apparatus measures value but also indicate that may there be phenomenon of blocking in gas piping, needs to be serviced.Therefore; the on-line measurement instrument relatively more abominable for the application scenario, that 24h runs without interruption; not only help fault pre-alarming in the low discharge alerting signal connecting system with the detection of gas flow pick-up unit; find fault early; and help, thereby play the purpose of protecting instrument at the power supply that the power device (pump) of internal system occurs cutting off automatically under the situation of reporting to the police.
The utility model content
The technical problems to be solved in the utility model provides a kind of gas flow monitoring device that is used for the extraction method flue gas discharge continuous monitoring system, during it can monitor the gas flow monitoring device the flow identical, send alerting signal and carry out fault pre-alarming with predefined warning flow.
In order to solve the problems of the technologies described above, the gas flow monitoring device that is used for the extraction method flue gas discharge continuous monitoring system of the present utility model comprises spinner-type flowmeter, and the side of described spinner-type flowmeter is provided with slide rail and slide block, and described slide block is provided with induction installation.
Adopt such structure since on spinner-type flowmeter fixing induction installation.Induction installation is near the warning flow scale mark of setting.When the float in the flowmeter floats at this scale place, trigger induction installation and send alerting signal.Therefore can carry out fault pre-alarming effectively.
The beneficial effects of the utility model are embodied in: 1. detected gas flow and send alerting signal effectively; Under the situation of take place reporting to the police after flow recovers normally alarm condition can automatically terminate; 3. the alarming value of flow can be adjusted; 4. with low cost, one-sided installation, it is convenient to change.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 shows concrete structure of the present utility model.The perforate of the side of spinner-type flowmeter 1 with slide rail 4 by screw retention on spinner-type flowmeter 1, induction installation 2 is fixed on the slide block 3.Induction installation 2 near the scale mark of spinner-type flowmeter 1 to increase sensing range and sensitivity.
Different alarm stream values is set in the position of slide block 3 on slide rail 4 that is fixed with induction installation 2 by adjusting.Because induction installation 2 near the warning flow scale mark of setting, triggers induction installation 2 and sends alerting signal when the float in the spinner-type flowmeter 1 floats at this scale mark place.
Claims (1)
1. gas flow pick-up unit that is used for the extraction method flue gas discharge continuous monitoring system, comprise spinner-type flowmeter, it is characterized in that: the side of described spinner-type flowmeter (1) is provided with slide rail (4) and slide block (3), and described slide block (3) is provided with induction installation (2).
