Embodiment

For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.

In conjunction with Figure 1 and Figure 2, the housing 1 at gasifier nozzle position and internals 2 respectively have four correspondences and symmetrical housing burner to take over 5 and four internals burner interfaces 6, and hoop becomes 90 ° of intersections to be divided into two-way, vertically be placed in ten meters dells 3 and dock measurement.The center of two internals burner interfaces 6 that the center of two housing burners adapters 5 of housing 1 symmetry is corresponding with internals 2, the right alignment≤3mm of assembly alignment, technical requirement is high.In conjunction with Fig. 5, the flow process of the measuring method that a kind of gasification furnace adapter provided by the invention position housing docks with internals is as follows:

Accurately locate at step 1, center: the housing burner adapter 5 of gasification furnace is relative with internals burner interface 6 is all small-bore, with the cross curve center, measure method, by at port, drawing two chalk lines, respectively the central point of 5 and four internals burner interfaces 6 of four housing burners adapters is accurately located.

Step 2, utilize light path to set up reference line: a transit 17 is respectively placed in the outside in two adjacent housing burners adapters 5, as shown in Figures 1 and 2, two transits 17 are placed on respectively 45 ° of housing burners and take over 5 and 135 ° of housing burners adapter 5 outsides, transit 17 belows are furnished with horizontal mobile device 16, and the below of horizontal mobile device 16 connects tripod 15.Corresponding two the housing burners of take are respectively taken over 5 central point and are reference point, the angular adjustment by transit 17, horizontal mobile device 16 move left and right the lifting with tripod 15, utilize light path to set up two reference lines.As shown in Figure 1, a transit 17 is set up the first reference line 18 at 45 ° of housing burners adapter centers 7 and 225 ° of housing burners adapter centers 9; Another transit 17 is set up the second reference line 19 at 135 ° of housing burners adapter centers 8 and 315 ° of housing burners adapter centers 10.

Step 3, the deviation at the center of measurement homonymy or two internals burner interfaces 6 of rear side: at homonymy or the rear side of two transits 17, place two adjustable backlight reading devices 20.In the present embodiment, take the homonymy that two adjustable backlight reading devices 20 are placed on to two transits 17 is example.In conjunction with Fig. 3 and Fig. 4, adjustable backlight reading device 20 comprises support bar 22, extension rod 23 and illuminating torch 24 and standard grid 25.

Two adjustable backlight reading devices 20 are placed on respectively the homonymy of two transits 17, with the fixing adjustable backlight reading device 20 of magnetic V block 21, make two standard grids 25 lay respectively at the back of 45 ° of internals burner interface centers 11 and 135 ° of internals burner interface center 12 cross curve, adjust support bar 22, extension rod 23 and illuminating torch 24, two standard grid 25De centers are overlapped with the point of crossing of 45 ° of internals burner interface centers 11 and 135 ° of internals burner interface center 12 cross curve respectively, 45 ° of internals burner interface centers 11 of survey record are with respect to the first reference line 18, 135 ° of internals burner interface center 12 deviations with respect to the second reference line 19.

Step 4, the deviation at measurement rear side or two internals burner interface centers of homonymy.What in step 3, measure is the deviation at center of two internals burner interfaces 6 of homonymy, this step adopts the method identical with step 3 to measure the deviation at the center of two internals burner interfaces 6 of residue rear side, what in step 3, measure is the deviation at center of two internals burner interfaces 6 of rear side, this step adopts the method identical with step 3 to measure the deviation at the center of two internals burner interfaces 6 of residue homonymy, in the present embodiment, the steps include:

Again two adjustable backlight reading devices 20 are placed on respectively to the opposite side of two transits 17, with the fixing adjustable backlight reading device 20 of magnetic V block 21, make two standard grids 25 lay respectively at the back of 225 ° of internals burner interface centers 13 and 315 ° of internals burner interface center 14 cross curve, adjust support bar 22, extension rod 23 and illuminating torch 24, make two standard grid 25De centers respectively with 225 ° of internals burner interface centers 13, the point of crossing of 315 ° of internals burner interface center 14 cross curve overlaps, 225 ° of internals burner interface centers 13 of survey record are with respect to the first reference line 18, 315 ° of internals burner interface center 14 deviations with respect to the second reference line 19.

Step 5, deviation processing:

If four internals burner interface 6 centers housing burner is relatively separately taken over the deviation of 5 center reference straight lines (the first reference line 18 and the second reference line 19), all meet technical requirement, the fixing internals of spot welding, measure end; Otherwise, in four internals burner interface 6 centers housing burner is relatively separately taken over the deviation of 5 center reference straight lines (the first reference line 18 and the second reference line 19), as long as there is the centre deviation of an internals burner interface 6 to be greater than technical requirement, will be according to direction and the size of deviation adjusting internals.Again according to the operational measure deviation of step 3 and step 4, until the deviation of four internals burner interface 6 centers housing burner adapter 5 center reference straight lines (the first reference line 18 and the second reference line 19) relatively separately meets technical requirement, spot welding is internals fixedly, measure and finish.
