Abstract
A trapezoidal distributing barrel of a strip-shaped net comprises a plurality of trapezoidal supporting plates, a supporting plate connecting frame, an arc-shaped back housing plate and a plurality of net strips; the trapezoidal supporting plates are equidistantly arranged inside the supporting plate connecting frame uniformly and welded on the supporting plate connecting frame; the net strips are arranged at set intervals and welded on the equidistantly arranged trapezoidal supporting plates to form the strip-shaped net; and the arc-shaped back housing plate is fixedly connected with the supporting plate connecting frame. In the utility model, as the arc-shaped back housing plate is adopted and thickened, the wear resistance and the high temperature resistance of a back plate are improved; the formed cambered-surface trapezoidal strip-shaped net has good impact resistance, distortion resistance, bending resistance and tensile resistance and has no deformation, cracking and the like when temperature is changed; and the strip-shaped net is axially arranged and gaps are uniform and vertical, so the pressure drop is avoided, the flow resistance of a catalyst is reduced and the friction and collision to the catalyst is reduced; and the service life of the distributing barrel is more than 20 years.
Description
Technical field
The utility model relates to the material distribution tube in the reformation reflecting device, particularly relates to strip net trapezoidal profile tube.
Background technology
Domestic in the past reforming reactor trapezoidal profile tube adopts some long open-works of the thick corrosion resistant plate cold punching of 1.2-1.5mm and drawing to form fully, its plate is thin shock-resistant, withstand voltage properties is poor, be prone to distortion, bending defect, open-work edge through punching out processing retains burr, its stretching makes surperficial rough and uneven in surface distortion, and its open-work is transversely arranged slotted hole, and fluidized-bed catalyst is existed friction, collision, cause the breakage rate of catalyst to rise, increase the magnitude of recruitment of catalyst.Trapezoidal tube a large amount of depressed deformations occur for thin plate processing is in throughout the year under the environment such as high temperature, burn into stretching, service life is short, and the longest under the normal process conditions is 6 years, has increased the probability of parking maintenance.
The utility model content
The technical problems to be solved in the utility model, provide and a kind ofly reduce catalyst friction, collision and reduce replenishing of catalyst, have shock resistance, anti-twist, bending resistance, tensile property, distortion, cracking when variations in temperature, can not occur, the strip net trapezoidal profile tube of long service life.
The technical scheme that adopts is:
Strip net trapezoidal profile tube comprises trapezoidal gripper shoe, gripper shoe connection box, curved rear coverboard, net bar.Described trapezoidal gripper shoe is a plurality of, evenly be laid in the gripper shoe connection box with equidistant, and be welded on the gripper shoe connection box, many net bars are arranged with the distance of setting and are welded on the trapezoidal gripper shoe of a plurality of equidistant layings, form the strip net, the curved rear coverboard is fixedly connected on the gripper shoe connection box, surrounds trapezoidal tube.
Above-mentioned net bar is axially to be provided with.
Above-mentioned its cross section of net bar is an isosceles triangle, with 90 ° of vertical welding of its inverted triangle and trapezoidal gripper shoe.
Above-mentioned curved rear coverboard is the overall structure plate.
The utility model adopts curved rear coverboard and thickening, has improved wear-resisting, the heat-resisting quantity of backboard.The trapezoidal strip net of formed cambered surface has good shock resistance, anti-twist, bending resistance, tensile property, accidents such as distortion, cracking can not occur when variations in temperature, the strip net is axially to be provided with again, and the slit evenly, vertically, can not produce pressure and fall, reduce the flow resistance of catalyst; Friction and collision that catalyst is produced have been reduced.Reach service life more than 20 years.
