[utility model content]
For solving problems of the prior art, the utility model proposes a kind of corrugated plate dst denitrification catalyst module framework, framed structure is reasonable, easy to adjust, and assembling is simple, substantially increases the efficiency of assembling of corrugated plate dst denitrification catalyst module.
For achieving the above object, the utility model adopts following technological means:
A kind of corrugated plate dst denitrification catalyst module framework, comprising: the space framework be spliced into by underframe, upper side frame and pillar stiffener, and the assembling of denitrating catalyst unit is fixed in framework; Underframe adopts Integral welded structure; Upper side frame forms quadrilateral structure by crossbeam, and corner connector is welded perpendicular to the angle steel of any mutually by three, and two crossbeams and pillar stiffener are fixed by corner connector; Corner connector and crossbeam are provided with multiple continuous print mounting hole, and fasteners through mounting holes fixes corner connector; Four angles of upper side frame are provided with hanger, and base of frame is connected with base.
Described upper side frame is also provided with intermediate beam and lacing wire, and the crossbeam of intermediate beam and upper side frame is fixed by fastener; The crossbeam of lacing wire and intermediate beam, upper side frame forms triangular structure, and is fixed by fastener; Also be provided with lacing wire between the crossbeam at four angles of upper side frame, lacing wire and crossbeam are fixed by fastener.
Also be provided with column between described underframe and upper side frame, column and pillar stiffener be arranged in parallel, and are fixed on underframe and upper side frame by fastener.
Described fastener is countersunk-heat bolt, and fastener receptacles is countersunk screw holes.
Described crossbeam adopts band steel to make, and pillar stiffener adopts angle steel to make.
Described denitrating catalyst unit has 16, divides two-layer being arranged in framework
Relatively and prior art, the utility model has the following advantages:
The utility model is that module frame lower frame is adopted general frame structure, and upper side frame adopts Assembly of the parts structure, and assembly crewman revises catalyst elements assembling effect by regulating upper ledge nut and part gap.Thus solve general frame module frame upper side frame cannot regulate cause assemble difficult problem.Well solve in denitrification catalyst module assembling process and not easily adjust, occur the problems such as distortion, improve enterprises production efficiency.
Further, because denitrification catalyst module is placed in superposition, increase intermediate beam and lacing wire are used for meeting frame roof Structural strength calls.
Further, column is increased, for meeting the requirement of strength of frame supported power.
Further, the setting of countersunk-heat bolt and countersunk screw holes, on the one hand facilitates frame assembled, and prevent unnecessary extending bolt to collide with catalyst elements, another conveniently meets aesthetic.
