Description
Technical field
The utility model relates to a kind of air preheater radial seal ruler structure, relates in particular to the radial seal ruler structure in a kind of rotary regenerative air preheater, belongs to air preheater field.
Background technique
Rotary regenerative air preheater is a kind of equipment that carries out heat exchange by continuous rotation, so exist flue gas corridor between the rotor of rotation and static intermediate beam and circular arc coverboard, to make like this fume side flue gas directly by this passage, be leaked to air side, the air leak rate of air curtain that has had a strong impact on preheater, greatly reduces heat exchange efficiency.
In order to stop the direct leakage of flue gas, on the intermediate beam of air preheater and a wind beam, radial seal plate is all installed, and on the radially dividing plate of rotor, apex seal has all been installed, thereby stoped the direct leakage of flue gas, guaranteed heat-exchange performance.But the continuous variation along with boiler heat load, the rotor of air preheater is in operation and can presents " mushroom " distortion, the thermal expansion amount in inner side, hot junction and outside is also all different, therefore, when cold conditions is installed, just need to consider thermal expansion because usually rationally adjusting the seal clearance of everywhere diaphragm seal, radial seal ruler is exactly a kind of special tool that is used for adjusting radial seal gap in installation process.
As shown in Figure 1 and Figure 2, for common radial seal ruler structure and radial seal chip architecture, this radial seal ruler supports angle steel 1, the first intermediate support angle steel 2, the first channel-section steel 3, the first adjusting bolt 4, clamping bolt 5 and nuts and washers by first of both sides and forms.When mounted, first the first support angle steel 1 is welded on respectively on the seal disc of preheater inner side and the flange ring in outside, on the first channel-section steel 3, have vertical oval hole, by adjusting the first adjusting bolt 4, can regulate the first channel-section steel 3 to move up and down within the specific limits to make it meet the requirement of levelness, on the first support angle steel 1 and the first intermediate support angle steel 2, have transverse waist circular hole, can make the position of the first channel-section steel 3 adjust left and right within the specific limits, after adjustment, by use clamping bolt 5, its position is fixed, thereby complete setting up of this radial seal ruler, subsequently, the apex seal being arranged on rotor radial dividing plate all be take this ruler as standard, according to the seal clearance value of the every section of diaphragm seal calculating, adjust piecewise, thereby meet the performance requirement of unit operation.
Yet constantly perfect along with the continuous increase of unit capacity and radial seal technology, has invented again the radial seal technology of soft seal, as shown in Figure 3, is the radially soft sealing structure of semi-module rotor structure; As shown in Figure 4, be the radially soft sealing structure of full modular structure.By installing again twice soft seal sheet additional on the basis in original conventional seals chip architecture, greatly promoted the effect of sealing, but because the cross section of three seals sheet integral body broadens, also there is a departure A in the mounting point of soft seal sheet and conventional seals sheet, so common radial seal ruler structure cannot meet the requirement of its adjusting.
In order to regulate the radially seal clearance of soft seal sheet, again specialized designs soft radial seal ruler, as Fig. 5, shown in Fig. 6, by being welded with several block plates 6 in the first channel-section steel 3 bottoms on the basis in original radial seal ruler structure, can there be enough width, and because mounting point and the conventional seals sheet of soft seal sheet have a departure, and this departure the is arranged in preheater size of inner side during with outside with diaphragm seal is not identical yet, in order to meet the levelness of ruler and to regulate requirement, also need to take mach mode to form stepped shaft to the lower end surface of steel plate 6 and meet installation requirement, therefore sealing ruler structure is to add man-hour more difficult, once and the departure after processing can not change, not only increased the processing cost of material, but also cannot meet the adjustment requirement of soft seal sheet completely.
Summary of the invention
The technical problems to be solved in the utility model is: provide that a kind of processing cost is low, install and adjust is convenient, practical reliable, highly versatile, air preheater radial seal ruler structure that using scope is wide, solved in traditional radial seal ruler structure, exist to add man-hour more difficult, once and the departure after processing can not change, not only increase the processing cost of material, but also cannot meet the problem that the adjustment of soft seal sheet requires completely.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of air preheater radial seal ruler structure, it is characterized in that, comprise the first angle steel, the outside Opposite direction connection of the outside of the first angle steel side and the second angle steel side, the outside of the second angle steel side is connected with the outside of the second channel-section steel bottom surface, the upper side of the second channel-section steel is all connected with the bottom surface of the first angle steel by the second adjusting bolt, the inner side of angle steel side is supported in the inner side of the second angle steel side and second, the inner side of the second intermediate support angle steel side connects, the second underrun the first adjusting bolt that supports angle steel is connected with the bottom surface of the first angle steel, second supports angle steel, between the second angle steel and the second channel-section steel, by clamping bolt, connect, the second intermediate support angle steel, between the second angle steel and the second channel-section steel, by clamping bolt, connect.
Preferably, the bottom surface of the downside of described the second channel-section steel and the second angle steel can be adjusted in same level, also can have relative deviation.
Preferably, the two ends of described the second channel-section steel bottom surface and centre are equipped with vertical oval hole, and its upper side is provided with tapped hole.
Preferably, the length of described the second channel-section steel is identical with the length of the second angle steel.
Preferably, above the side of described the second angle steel, be provided with vertical oval hole.
Preferably, the bottom surface of described the first angle steel is provided with two circular holes.
Preferably, on described the second support side of angle steel and the side of bottom surface and the second intermediate support angle steel and bottom surface, be equipped with transverse waist circular hole.
The utility model manufacture method is simple, practical reliably, versatility is stronger, not only can be for common diameter in sealing configuration, also can be for thering is the radial seal structure of soft seal technology, using scope is wider, regulate installation also convenient flexible, and be conducive to the Seriation Design of sealing ruler structure.It is by using the built up construction of several different structure angle steel, not only relaxed measurement datum width, two reference levels have been had, and can carry out the adjusting of two reference level relative positions, install and adjust is convenient, the installation requirement that has met the apex seal with soft seal technology completely, has reduced processing cost.
