Abstract
The utility model discloses a pulverized coal fineness metering system, which comprises a measuring probe, a controller and a power supply, wherein the measuring probe can be inserted into a coal pipe and is connected with the controller through a hybrid cable control line; the controller is provided with a notebook computer and the controller and the notebook computer are connected with the power supply respectively; and the controller is also connected to a compressed air source through a compressed air pipe. The pulverized coal fineness metering system can be used for measuring the pulverized coal fineness on line and has high measuring accuracy, so that the aims of energy conservation and emission reduction are fulfilled.
Description
Technical field
The utility model relates to the thermal power generation field, particularly a kind of a kind of fineness of pulverized coal metering system for the fuel-burning power plant.
Background technology
Fineness of pulverized coal refers to the shared quality percentage of the particle of different-diameter in the coal dust.Usually says that improving fineness of pulverized coal is that coal dust is attenuated, can make like this that coal dust catches fire, burn fully easilier, the possibility of unburned carbon in flue dust reduction, minimizing secondary combustion; The furnace flame center reduces relatively simultaneously, the stove effect is relative raises.Understand corresponding adding but raising fineness of pulverized coal, the power consumption of pulverized coal preparation system increase, the coal-grinding component wear increases in the coal pulverizer, increases maintenance.So for power plant, the debugging unit can provide the reference value of the normal coal amount in service of coal pulverizer and electric current according to the ground coefficient of design coal.
At present, do not have a kind of effective equipment, coal dust often can not harmonious combustion in the on-line measurement fineness of pulverized coal accurately, boiler, and the oxides of nitrogen that causes discharging exceeds standard, and is difficult to satisfy environmental requirement.
The utility model content
The purpose of this utility model provides a kind of fineness of pulverized coal metering system, can the on-line measurement fineness of pulverized coal, and the measuring accuracy height, thus reach the purpose of energy-saving and emission-reduction.
The technical solution of the utility model is: a kind of fineness of pulverized coal metering system, comprise the measuring sonde that can insert the coal pipe, and also comprise controller and power supply, described measuring sonde links to each other with controller by the compound cable control line; Described controller is provided with notebook computer, and the two links to each other with power supply respectively; Described controller also is connected to compressed air source by compressed air hose.
Because the position of measuring sonde in the coal pipe is different because of the degree of depth, therefore, the bar portion of measuring sonde described in the utility model is provided with the adapter that it can be clamped the location.
Adapter described in the utility model can be the superpressure adapter; Can also be the low pressure adapter.
Be provided with air strainer between controller described in the utility model and the compressed air hose.
Notebook computer described in the utility model links to each other with controller by USB cable.
The bar portion of measuring sonde described in the utility model also is provided with ball valve, is used for regulating and the control pulverized coal flow.
The beneficial effects of the utility model are:
Fineness of pulverized coal metering system of the present utility model, by the on-line measurement fineness of pulverized coal, the measuring accuracy height can make the interior coal dust firing of boiler abundant, effectively reduces the discharge capacity of oxides of nitrogen, compliance with environmental protection requirements.The utility model operation, simple installation, practical.
Description of drawings
Fig. 1 is the fineness of pulverized coal metering system structural representation sketch of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Specific embodiment of the utility model as shown in Figure 1, a kind of fineness of pulverized coal metering system comprises the measuring sonde 1 that can insert the coal pipe, also comprises controller 2 and power supply 3, measuring sonde 1 links to each other with controller 2 by compound cable control line 4; Controller 2 is provided with notebook computer 5, and the two links to each other with power supply 3 respectively; Controller 2 also is connected to compressed air source 7 by compressed air hose 6.
In the present embodiment, the bar portion of measuring sonde 1 is provided with the adapter 8 that it can be clamped the location.Adapter 8 can be the superpressure adapter, can also be the low pressure adapter, and the selection of adapter mainly determines according to environmental baseline.
Be provided with air strainer 9 between controller 2 and the compressed air hose 6.Notebook computer 5 links to each other with controller 2 by USB cable.The bar portion of measuring sonde 1 also is provided with ball valve 10.
In the above embodiments, insert in wind pulverized coal channel 11 end of measuring sonde 1, and fix by wire connection 12 and pulverized coal channel 13.
In the above embodiments, ball valve 10 plays the effect of switch pulverized coal channel, and ball valve 10 front and back all are provided with internal thread, and front end is connected with wire connection 12, and wire connection 12 is welded on the pulverized coal channel 13 and plays fixation, and ball valve 10 rear ends are connected with adapter 8.Mounting adapter 8 during measurement, open ball valve 10 to ball valve 10 rear ends, are convenient for measuring probe 1 and insert, and measure to finish the back and take out measuring sonde 1, close ball valve 10, prevent that coal dust from revealing, and pull down adapter 8 and it is installed on the next pipeline that needs measurement.
The above embodiments only are preferred embodiment of the present utility model, can not limit interest field of the present utility model with this, and therefore, the equivalent variations according to the utility model claim is done still belongs to the scope that the utility model is contained.
