Description
Technical Field
The utility model relates to a flue gas sampling metering device.
Background
The analysis and calculation of the content and the components of the flue gas in the flue gas duct of the boiler are completed by a continuous flue gas monitoring system (CEMS for short), and the main measurement data comprises the following data: main parameters such as SO2, NOx, O2 and the like, and other gases such as chloride ions, carbon monoxide and the like in the flue gas duct of the boiler cannot be measured, analyzed and calculated by a CEMS system. In order to sample the flue gas, a small fan or an air pump is adopted to extract more flue gas at present, flow monitoring and flow control are not available, and blindness is high. In summary, how to quickly and accurately measure the contents of chloride ions and carbon monoxide in the flue gas duct of the boiler has become a first technical challenge for technicians.
Disclosure of Invention
The utility model aims at providing a smoke sampling and metering device, the problem that a certain gas cannot be measured and analyzed due to the fact that a smoke component analyzer is not installed is solved. The technical scheme of the utility model is that: the utility model provides a flue gas sample metering device, by flue gas sample pump (1), float flowmeter (2), connecting pipe (3), intake pipe (4), air inlet valve (5), blast pipe (6) and receiving flask (7) are constituteed, the entry of float flowmeter (2) is connected to intake pipe (4) one end, air inlet valve (5) are connected to intake pipe (4) other end, the export and connecting pipe (3) of float flowmeter (2) are connected, the other end and the entry linkage of flue gas sample pump (1) of connecting pipe (3), exit linkage blast pipe (6) of sample pump (1), receiving flask (7) are connected to the exit end of blast pipe (6).
The float flowmeter (2) is a metal tube float flowmeter, and the flow rate is 0-1.5 liters/minute.
The utility model discloses a theory of operation:
the utility model discloses a be connected through sampling tube and on-the-spot pressure measurement station sample connection or flue gas sample connection in the continuous monitoring system rack of flue gas, close the sampling pump power, make the sampling pump rotatory, adjusted the metal float flowmeter and prepared measurement work, then pass through the sampling pump to the flue gas in the boiler flue gas wind channel in an inclosed receiving flask, store its composition of chemical examination analysis and content.
The utility model discloses technological effect:
the utility model discloses a be connected through sampling tube and on-the-spot pressure measurement station sample connection or flue gas sample connection in the continuous monitoring system rack of flue gas, the gas in the extraction pipeline carries out analysis chemical examination, because flowmeter and sampling pump have been installed to this device, conveniently carries out the control of flow monitoring and sample total amount, and the sampling tube interface adopts the standard formula structure of connecing soon, convenient operation, has solved because of not installing a certain flue gas composition analysis appearance and has leaded to unable the problem of taking a sample measurement and analysis to this gas.
