Description
Technical field
A kind of anti-blocking apparatus for measuring air quantity of array is the utility model is related to, suitable for wind turbine wind used in boiler and supporting power generation
Amount detection.
Background technology
Boiler air-supply automatic adjustment is the element of burning self-regulation, and the work of air blast regulating system is fine or not,
Directly affect the oxygen content for changing namely discharge flue gas that the air excess of burner hearth is counted accurately.And the key for regulation technology of blowing is
Air-flow measurement.The economy of Combustion Operation of Boilers depends primarily upon whether coal-air ratio is appropriate, and air quantity is too big, and flue gas can be taken away
Amount of heat reduces boiler efficiency, and air quantity is too small, and fuel can be made, which to can't burn completely because of anoxic, can equally imitate boiler
Rate reduces, so the detection of boiler air-supply volume has great significance for the economy of boiler operatiopn, he can not only make operation
Personnel monitor the mated condition of coal-air ratio at any time, and the input of also non-wind turbine automatic regulating system provides necessary condition.Therefore it is right
The accurate measurement for entering stove air plays an important role.
Utility model content
The device is designed according to international flow measurement standard (iso3966), based on S type pen tray pipes to measuring principle, measurement
Device is installed on pipeline, and in probe insertion pipeline, when there is flow in pipeline, the kinetic energy of air-flow is converted into pressure energy here
Amount, thus air inducing overpressure is higher, this pressure becomes total head, and leeward side due to being from gas shock, its manifold pressure
The difference of static pressure in air hose, total head and static pressure becomes pressure difference, and air velocity has direct relation in its size and pipeline, and into just
Than its relation meets Bernoulli equation.
Technical solution is used by the utility model solves its technical problem：A kind of anti-blocking apparatus for measuring air quantity of array,
It is characterized in that：Include at least：Sensor stand, sensor stand are fixed on the vent passages of pipeline, and sensor stand is cylinder
Shape structure, there is mesh-supported in cylindrical body, and the sensor of array arrangement is fixed with mesh-supported point, and lead arranges array
Sensor connection, guided into by pipe side wall outside pipeline.
The mesh-supported is connected and composed by being distributed wire in length and breadth, and sensor is fixed on is distributed wire connection in length and breadth
Point on.
The mesh-supported have in sensor stand it is multigroup, it is multigroup before in after arrangement, make sensor in the logical of pipeline
Different Plane position and space length distribution on wind passage.
The sensor is ellipsoid, there is strain resistor on oval body wall, and strain resistor is surveyed with the resistance in ellipsoid
Circuit is measured to be electrically connected.
The resistance measuring circuit is bridge-type measuring and amplifying circuit.
The ellipsoidal elliptical shaft is parallel with the vent passages of pipeline, and sensor provides the resistance deformation quantity of side arm,
Ventilation pressure is calculated by resistance deformation quantity.
The utility model has beneficial effect following prominent：
The automatically cleaning and choke preventing function possessed due to itself, makes her be provided with the excellent of differential pressure type air-flow measurement device
Point, turn avoid differential pressure type flow meter and requires the shortcomings that high to air passage arrangement.The device is able to ensure that what is measured for a long time
Accuracy, can show the size of flow in each air hose in time, and adjust the operation of boiler at any time, allow boiler always in economic scene
Lower operation, improves the automatic input rate of boiler, and the anti-blocking array type apparatus for measuring air quantity detection pressure loss is small, saves wind
The power consumption of machine, increases the economy and the feature of environmental protection of boiler.
The device has the advantage that in the detection and feature：1st, because the device has with automatic using fluid dynamic energy in itself
Deashing function, therefore it is avoided that the problem of dirty impurity causes pressure obtaning device to block.Even if the 2, the inadequate length of straight pipe at the scene,
The present apparatus also can accurately measure flow in the case of can not meet general flowmeter testing conditions.3rd, using plug in construction,
It is easy for installation, extraction repair and maintenance can be carried out in the case where not stopping production, energy-saving effect is very notable.
