Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.It should be noted that making in being described below
Word "front", "rear", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" respectively refer to
Be directed towards or far from geometric center of specific component direction.
As shown, protective device, including chimney body 1 is transformed in a kind of chimney band cigarette aperture described in the utility model,
It is equipped at least twice annular girder 2 on the outside of the chimney body 1, smoke inlet 3 is equipped between annular girder 2,3 two sides of smoke inlet are equipped with angle
Then steel 4 is connect with angle steel 4 with 2 blocks of steel plates 5 by removable pin 6 respectively, form a fan double door 7, the ring of 3 lower section of smoke inlet
Operating platform 8 is equipped on the outside of ellbeam, the operating platform is equipped with riser station 9, is equipped with horizontal direction above the riser station 9
Sliding rail 10, the 10 direction face smoke inlet 3 of sliding rail.
Process flow
Need reinforcement the crack at position to chimney first and the concrete that has corroded of part reject it is clean, again to cigarette after repairing
Concrete Ring Beam is added on the outside of chimney and reinforces its intensity of raising, aperture then is carried out to selected location, and personnel stand in operating platform 8
Upper punching is punched in chimney side and takes out concrete block, ultimately formed smoke inlet 3, opened with XX coking desulfurization denitration transformation project
For pore size (rectangle 2.5m*2.6m), since bore size is larger, concrete block weight about 6.175t, for guarantee safety,
Prevent concrete block taking-up moment from can generate greater impact power, so being divided to two pieces from centre for 2.5m*2.6m concrete, in two times
