Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
Referring to shown in Fig. 1 to Fig. 3, the invention discloses a kind of boiler furnaces, including insulation of wall layer 10, are arranged on furnace wall
Outside monowall tube 20 on 10 medial surface of insulating layer and the insulation of wall layer being arranged on 10 lateral surface of insulation of wall layer
Backplate 30.
Insulation of wall layer 10 of the present invention is equipped with the wedge groove 40 through insulation of wall layer 10 along circumferential direction, and wedge groove 40 makes
The back-fire side of monowall tube 20 and boiler furnace turned on outside are obtained, wedge groove 40 is close to the length of 20 one side of monowall tube
Degree is less than length of the wedge groove 40 close to one side outside boiler furnace.
Boiler furnace further includes wedge shape heat preservation dodge gate 50, and wedge shape heat preservation dodge gate 50 is identical with the shape of wedge groove 40,
Wedge shape heat preservation dodge gate 50 is mounted on by the way of it can from top to bottom open in wedge groove 40, and this structure is similar to univalve door
Switch form, switch direction be vertical direction；Wedge shape heat preservation dodge gate 50 is to keep the temperature dodge gate with tapered wedge shape,
It is easily opened during use；The side that wedge shape heat preservation dodge gate 50 is contacted with insulation of wall layer 10 is equipped with sealant（In figure not
It marks）, sealant is used to prevent the hot gas of 20 back-fire side of monowall tube from passing through wedge shape heat preservation dodge gate 50 and insulation of wall
Clearance leakage between layer 10 improves security to outside boiler furnace.
Wedge groove 40 and wedge shape heat preservation dodge gate 50 number determined according to the face number of boiler furnace, the present invention in Boiler Furnace
Thorax is rectangular parallelepiped structure, and therefore, the number of wedge groove 40 and wedge shape heat preservation dodge gate 50 is 4.
Boiler water-wall tube temperature is measured the selection at position, can be carried out according to the structure of boiler water-wall tube, is tested
The representative position in amount position is typically located at the exit of vertical water-wall tube（I.e. wedge groove 40 is located at vertical membrane type water
The exit of cold wall pipe 20）, but this position is not limited to, it can also be according to the different absolute altitude position of the different selections of purpose of measurement
It puts, it, should for the position of water-cooling wall temperature monitoring possibly even for the temperature survey of other heating surfaces for having an external thermal insulation wall
It selects as far as possible on the section of the same absolute altitude of boiler water wall, to improve the accuracy of temperature survey, relativity.
Wedge shape heat preservation dodge gate 50 is made of insulating layer 51 and the outer casing 52 being arranged on insulating layer lateral surface, insulating layer
51 are equivalent to insulation of wall layer 10, and outer casing 52 is equivalent to insulation of wall layer outer casing 30.
The upper end of wedge shape heat preservation dodge gate 50 of the invention carries out /V by backstop button 60, and insulation of wall layer 10 is close to wedge shape
The insulation of wall layer outer casing 30 for keeping the temperature 50 upper end of dodge gate is equipped with screw 70, and one end of backstop button 60 is rotatably set in
On screw 70（Backstop button could only be rotated when being subject to external force around screw, not rotated usually）, when backstop button 60 outside
When rotating to vertical position around screw 70 under the action of power, the other end of backstop button 60 is fitted in 50 upper end of wedge shape heat preservation dodge gate
Outer casing 52 on, for prevent wedge shape heat preservation dodge gate 50 outwards open；When backstop button 60 rotates to horizontal level, backstop
The other end of button 60 leaves from the outer casing 52 of 50 upper end of wedge shape heat preservation dodge gate, and is protected positioned at the furnace wall of insulation of wall layer 10
On warm layer outer casing 30.
The lower end of wedge shape heat preservation dodge gate 50 of the invention is fixed by hinge 80, and one end of hinge 80 is consolidated by screw
It is scheduled on the outer casing 52 of wedge shape heat preservation dodge gate 50 lower end, it is close that the other end of hinge is fixed by screws in insulation of wall layer 10
On the insulation of wall layer outer casing 30 of 50 lower end of wedge shape heat preservation dodge gate；When backstop button 60 keeps the temperature 50 upper end of dodge gate from wedge shape
After being left on outer casing 52, wedge shape heat preservation dodge gate 50 can from top to bottom be overturn by hinge 80, so that fin panel casing
The back-fire side of pipe 20 is naked to be exposed on the external.
The method of water screen tube temperature is as follows in present invention measurement boiler furnace：
（1）Rotational stop button 60 to horizontal level, backstop button 60 leaves from the outer casing 52 of 50 upper end of wedge shape heat preservation dodge gate,
Wedge shape heat preservation dodge gate 50 is opened, wedge shape heat preservation dodge gate 50 downwardly turns under the action of hinge 80, at this point, fin panel casing
The back-fire side of pipe 20 is towards outside；
（2）Temperature measurer is aimed at infrared laser to measure every exposed water-cooling wall pipeline, naturally it is also possible to which it is suitable to select
Contact thermocouple or bimetallic temperature measurer measure.
Advantages of the present invention further includes：
1st, when needing to carry out thermometric to water screen tube, wedge shape heat preservation dodge gate can be opened at any time and is measured；
2nd, this method compares and installs wall temperature measurement point on every pipeline additional, implementation process is more convenient and easy and also expense very
It is cheap；
3rd, in terms of reliability compared with other methods, due to being direct wall temperature measurement, the transmission process of no intermediate data information, and
In-site measurement is easy to correct, therefore the data measured are relatively reliable, can substantially ensure the accuracy of data acquisition.
The basic principles, main features and the advantages of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
