Description
Technical field
The utility model relates to temperature and pressure streams to monitor field, and in particular to a kind of flow integrated monitor of temperature and pressure.
Background technique
The mode of temperature, pressure flow velocity while measurement is generallyd use currently used for Online monitoring of pollution sources, main purpose is
Flue gas flow under measurement standard state.Measurement temperature and pressure is actually to compensate flowmeter calculation.When industry spot needs
When counting pollutant discharge amount, it is common practice that standard state pollutant concentration is carried out the meter that is multiplied with standard state flow
It calculates, the result of computational chart is as pollutant discharge of enterprise statistical data.Therefore, temperature, pressure, stream is usually taken when carrying out flow measurement
The mode that fast (flow) measures simultaneously.
Disadvantage of the prior art is that: some point in flue is usually only measured when measurement, and section is represented with the flow velocity
Mean flow rate, if the measuring point is located at flue center, error is opposite can be smaller, since industry spot is widely different, when measurement
It is typically only capable to certain point in measurement flue, in flue under complex situations, the same stability of measurement result is relatively low.
To solve the above-mentioned problems, publication number CN207456512U discloses a kind of flow integrated monitor of temperature and pressure, including
Flue, fuselage, the fuselage are located at outside flue, are characterized in that: the fuselage side is extended with installation frame, the installation
Frame is fixed with flue sidewall, and the installation frame is equipped with three connectors being connected to fuselage, the connector detachable
It is connected with Pitot tube, the Pitot tube end is located at different location in flue, is respectively equipped on three Pitot tubes and fuselage
The pressure transmitter of connection, the interior temperature sensor being equipped with for detecting temperature in flue of the flue, the installing frame are set up
There is the regulating device for adjusting temperature sensor location.Three Pitot tube ends are located at flue center and close to two sidewalls
At position, the position of three representative flow velocitys in real-time detection flue represents final flue gas flow using average value, as a result
It is more accurate.
Although above-mentioned patent solves the problems, such as that traditional technology measurement point is single, but averaged using three Pitot tubes
The one of instrument error of Shi Yidan will lead to the structure measured and great deviation occurs, next three measurement point position is not
Together, it is not directed to different location
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of flow integrated monitor of temperature and pressure, no
It is only able to solve traditional single-point and detects the unclear quasi- problem of existing data, while data are inclined caused by being also avoided that because of instrument damage
Difference.
The purpose of this utility model is achieved through the following technical solutions:
A kind of flow integrated monitor of temperature and pressure, including fuselage, mounting flange, stop flange, at least three Pitot tube components,
Pressure transmitter, temperature sensor, the fuselage are fixed on mounting flange side, and stop flange is fixed in the mounting flange other side,
The Pitot tube component is mounted on stop flange, and one group of pressure transmitter is respectively installed on each Pitot tube component, described each
Pitot tube component is made of two Pitot tubes arranged side by side, all Pitot tube components be in front of in after linear distribution, each Pitot tube group
The underface of part is each to fix a temperature sensor, and the temperature sensor is mounted on a screw rod threadably
On, described screw rod one end is fixed on stop flange, and the logical end of the Pitot tube component is crossed mounting flange and connected with stop flange
To fuselage, the pressure transmitter, temperature sensor output end are connected to fuselage.
The screw rod, using fixation is threadedly coupled, can make disassembly more with stop flange by the way of threaded connection
It is convenient.
Two root skin trustships of the Pitot tube component are each to fix a pressure transmitter, i.e., is pressed for every root skin trustship
Power detection, to provide corrected parameter, further increases the precision of measurement.
Screw thread mouth is provided on the mounting flange, the stop flange is provided with corresponding nipple, installation
Flange and stop flange are threadably secured connection.
The beneficial effects of the utility model are: comparing with traditional technology, multiple spot monitoring is not only arranged in this programme, while to every
One monitoring point is arranged two Pitot tubes and measures, and is analyzed by the comparison to measurement data larger so as to exclude error
Data so that measurement accuracy is corrected, meanwhile, pressure transmitter and temperature are separately provided for each Pitot tube
Degree sensor is further corrected, so that measurement accuracy is further promoted.
