Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust measuring device for a boiler dust collector,

The present invention relates to a dust measuring device for a boiler dust collector having a support, and more particularly, to a dust measuring device for a boiler dust collector having a support structure for stably and efficiently measuring dust contained in a combustion gas discharged from an electric dust collector To a dust measuring device for a boiler dust collector.

Fluidized bed combustion technology, which has been widely adopted in recent thermal power plants, is a method of burning pulverized coal to an appropriate size and blowing air at a suitable rate into a fluid medium such as limestone and sand to form a suspended fluidized bed Suspended Fluidzed Bed), which is supplied to the boiler and burned.

This circulating fluidized bed combustion has a very high heat transfer efficiency due to the direct heat transfer by the solid particles and the combustion temperature in the furnace is much lower than the in-furnace temperature of the pulverized coal combustion system and has the advantage of less facility damage such as corrosion and scale at high temperatures In addition, because of its unique combustion characteristics, it circulates until the fluidized medium is completely burned. Therefore, unlike the pulverized coal combustion type, it is possible to carry out low-carbon combustion with a low calorific value and a large amount of water, The generation of nitrogen oxides is remarkably reduced. This has the advantage of not requiring a separate denitrification facility (SCR or SNCR) to comply with the nitrogen oxide emission regulation.

For example, in the case of the conventional pulverized coal combustion system, a catalytic denitrification system (SCR-De NOx system) and a desulfurization facility have to be installed in order to satisfy the current atmospheric emission regulation standards due to limitations of the boiler design. In the case of the fluidized bed combustion system, the installation of the denitration facility and the desulfurization facility can be omitted or selectively employed.

Since the coal combustion boiler used in this circulating fluidized bed combustion technology generates a large amount of dust such as fly ash, a dust collecting facility is installed at the rear end of the boiler. Electrostatic precipitator is mainly used as a dust collecting facility. The exhaust gas discharged from the boiler is uniformly distributed through the rectifying plate on the inlet side and passes through the inside of the rectifier plate. The ash contained in the exhaust gas is discharged through the discharge electrode and the dust collecting plate The dust collected and collected by the electrode plate containing the poles was dropped into the hopper by the chattering apparatus to be treated.

Conventional prior art related thereto is disclosed in Korean Registered Utility Model No. 20-031741 entitled " Automatic Regenerative Electrostatic Precipitator "and Korean Patent Registration No. 10-293353 entitled" Apparatus and Method for Controlling Electrostatic Precipitator " There is a problem that the degree of contamination of the exhaust gas discharged from the engine can not be measured.

On the other hand, in the "Dust measuring device for boiler dust collector" of the Korean Patent Registration No. 10-1314297 for solving such a problem, the sensor is difficult to install and the multi-stage sense is welded and fixed in the duct, The accuracy of the measured value according to the measurement is lowered and the reliability due to the measurement is deteriorated.

Accordingly, an object of the present invention is to provide a dust measuring apparatus for a boiler dust collector having a support for accurately and efficiently measuring dust contained in the exhaust gas of a boiler discharged through an electrostatic precipitator.

It is another object of the present invention to provide a method and a device for the safe and rapid measurement of dust contained in the exhaust gas of a boiler, And to provide a dust measuring device for a boiler dust collector.

In order to accomplish the above object, the dust measuring apparatus for a boiler dust collector having a retainer according to the present invention is configured to slide inside a main sensor sphere and to project outwardly, a pulley is coupled to both sides of the main sensor sphere, An operation sensor socket for attaching and fixing the lower side of the operation wire to the main sensor sphere in an inserted state and a slider for sliding inside the operation sensor sphere so as to protrude to the outside, A supporting sensor which is fixed to a lower end of the support sensor so as to be firmly supported by the supporting sensor, and a cylinder which is installed outside the upper duct of the main sensor and which is coupled to the operation sensor, ; Wherein the support slit has a plurality of support slits formed upward from a lower end of the support slit, and a support bar which hinges the support slit at an upper portion of the support slit, An upper operation hole for vertically inserting a center hole perpendicularly to the center hole, and a connecting rod extending through the center hole to provide a resilient force, a support partition wall formed at the center of the support and a lower partition wall formed below the support partition wall, And a lower operation hole for penetrating the hole and passing the connecting rod through the center hole of the lower partition wall to provide a resilient force.

Accordingly, the dust measuring device for a boiler dust collector having the support of the present invention can move forward and backward by pushing and pulling the operating wire fixed to the main sensor socket and the supporting sensor socket while the operation sensor socket is advanced, When the rod of the cylinder is continuously advanced by doubling, the support provided with resilience to the support sensor is brought into close contact with the inner surface of the duct, and at the same time, the support bar is widened to maintain a firm support state. When the duct is in close contact with the duct, the spring of the upper actuating shrinks first, and the pressure plate pushes the gully protrusion of the supporting bar. As a result, the supporting bar rotates about the hinge and expands. In this state, the spring elasticity of the lower operating shrinks, Since it is in close contact and maintains a solid coupling state, It is possible to stably and efficiently measure the dust contained in the combustion gas discharged from the dust collector and to selectively measure a variety of information as well as dust by selectively attaching various measurement sensors, So that the dust contained in the exhaust gas of the boiler can be sensed and measured, and various measurement operations can be performed safely and quickly.

When the support sensor unit 130 is installed on the upper side of the operation wire 124 in the inserted state, A connecting block 132 for fixing and fixing the connecting block 132 is formed.

The support strip 141 is supported on the upper portion of the operation slit 142 by a hinge 141a to rotate the support slit 142. [ And an upper partition wall 143 is formed on the inside of the support bar 140. A center hole 143a is vertically formed in the center of the upper partition wall 143 and a connecting hole 143a is formed in the center hole 143a. And a lower partition wall 146 is formed on the lower side of the support partition wall 145. The lower partition wall 146 is formed on the lower side of the upper partition wall 144, It is preferable that the lower partition wall 146 is formed with a lower part 146a by drilling a center hole 146a perpendicular to the lower partition 146 and a lower part 146 by a connecting rod 147b through a center hole 146a of the lower partition 146 .
