At present, the slagging phenomenon of the water-cooled wall is observed through the observation hole of the water-cooled wall, but the method has a visual field blind area, the flame in the furnace is too bright, the slagging phenomenon of the water-cooled wall is difficult to see by naked eyes, and the thickness of a slagging layer cannot be seen.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an acquire system of boiler water-cooling wall slagging scorification state is apart from water-cooling wall distance everywhere through the precision measurement to distance when not slagging scorification is compared, thereby judges the thickness on whether slagging scorification and slagging scorification layer of water-cooling wall each department. The utility model has the advantages of with low costs, measure fast, the measuring accuracy is high.
The utility model discloses a following technical scheme realizes:
the utility model provides a system for obtain boiler water-cooling wall slagging scorification state, includes data processing unit, remote control unit and sets up in boiler combustor top, the regional millimeter wave radar of installing of boiler water-cooling wall of platen superheater bottom below, and the millimeter wave radar passes through the signal line and links to each other with data processing unit, and data processing module passes through the signal line and links to each other with remote control unit.
The utility model discloses further improvement lies in, the measuring direction of millimeter wave radar can be from top to bottom, horizontal hunting to acquire the distance of different measurement angles.
The utility model discloses further improvement lies in, and millimeter wave radar mounted position is in the water-cooling wall trompil outside to avoid stove interior high temperature to damage the millimeter wave radar.
The utility model discloses further improvement lies in, during operating condition, the not equidirectional distance can be measured to the millimeter wave radar to compare with the distance when boiler water-cooling wall does not slagging scorification, thereby judge whether slagging scorification of this direction department water-cooling wall, and the thickness on slag blanket.
The utility model discloses further improvement lies in, and every brickwork arranges a plurality of millimeter wave radars of installation to improve the measuring accuracy.
The utility model discloses further improvement lies in, when the same region of water-cooling wall detected the time by many millimeter wave radar, this department slagging scorification thickness is the average value that many millimeter wave radar detected the slagging scorification thickness.
The utility model discloses further improvement lies in, the region that needs the test, but has an ultrasonic radar to cover at least.
The utility model discloses further improvement lies in that millimeter wave radar can be replaced by laser radar.
The utility model discloses at least, following profitable technological effect has:
because the utility model discloses in, at the regional trompil installation millimeter wave radar of water-cooling wall or laser radar device, through measuring and the interior water-cooling wall distance of stove to convey measuring result to data processing unit and remote control unit, the whole system does not have and stove interior high temperature contact device, in addition because the equipment transformation is less, therefore equipment and test cost are low. The relative change of the measuring distance is used for judging whether the boiler water wall is slagging or not, so that the measuring speed is very high. Because no wearing parts and no consumable materials exist in the measuring process, the measuring cost is extremely low each time.
Compare with the equipment that has prevented pulverized coal boiler convection heating surface from staiing the slagging scorification, the utility model discloses newly-built or reform transform with low costsly, the test cost is low, test time quantum, and the test accuracy is high.

Detailed Description
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.
As shown in FIG. 1 and FIG. 2, the utility model provides a pair of acquire system of boiler water-cooling wall slagging scorification state, including data processing unit 7, remote control unit 8 and set up in 6 tops of boiler combustor, the regional installation millimeter wave radar 5 of boiler water-cooling wall of platen superheater 4 bottom below, millimeter wave radar 5 links to each other with data processing unit 7 through signal line 8, and data processing module passes through signal line 8 and links to each other with remote control unit 8.
The measuring direction of the millimeter wave radar can swing up and down, left and right, and therefore distances of different measuring angles are obtained.
The installation position of the millimeter wave radar is outside the opening of the water-cooled wall, so that the millimeter wave radar is prevented from being damaged by high temperature in the furnace.
During the operating condition, the millimeter wave radar can measure the distance of equidirectional not to compare with the distance when the boiler water-cooling wall does not slagging scorification, thereby judge this direction department water-cooling wall whether slagging scorification, and the thickness on slag blanket.
And a plurality of millimeter wave radars are arranged and installed on each furnace wall 3 to improve the test precision. When the same area of the water-cooled wall is detected by a plurality of millimeter wave radars, the thickness of the slag at the position is the average value of the thicknesses of the slag layers detected by the plurality of millimeter wave radars.
At least one ultrasonic radar can cover the area to be tested.
The millimeter wave radar can be replaced with a laser radar.
