Description
Technical Field
The utility model relates to a novel sled dress cold box belongs to cold box panel field.
Background
The air separation plant cold box is a box body device formed by welding steel components, the appearance of the box body device is cuboid (shown in figure 1), and equipment such as an air separation plant heat exchanger, a rectifying tower and the like are arranged in the box. Because the air separation plant is cryogenic equipment, the cold box needs to be filled with pearlife for heat insulation, and therefore the whole cold box needs to be a sealed type device.
The main components of a common cold box are shown in fig. 1-2, and comprise: stand, crossbeam, bracing, panel, strengthening rib constitute. The upright posts and the cross beams are generally H-shaped steel or square tubes, the inclined struts are generally round tubes, and the cold box panel is a leveling steel plate. The cold box is a closed box body device, the cold box upright post, the cold box cross beam and the cold box inclined strut form a main stressed member of the cold box, and the cold box panel is connected with the cold box cross beam and the cold box upright post by CO2 seal welding.
Under the general condition, the cold box panel is made of a 4mm carbon steel leveling plate, and after the cold box panel is welded with the stand column and the cross beam, the flatness of the cold box panel and the stress of the cold box panel are considered, and the cold box panel is required to be reinforced by reinforcing ribs. Due to the existence of welding stress, local deformation often exists after the cold box panel is welded, and local leveling of the cold box panel is also needed for meeting the requirement of flatness of the cold box surface, so that relatively much time and procedures are often needed in the aspects of welding and leveling of the cold box panel.
In the design and manufacture of the skid-mounted cold box of the small air separation device, in order to meet the market demand, the manufacturing cost and the manufacturing time need to be reduced as much as possible, so how to save materials and reduce manufacturing procedures by optimizing the structure of the cold box, thereby saving equipment investment becomes the key of thinking problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to optimize the design of cold box panel structure, through a new corrugated type cold box panel structure design, and reach the novel cold box design of optimizing structure, save material and reducing manufacturing procedure.
The purpose of the utility model is accomplished through following technical scheme: the utility model provides a novel sled dress cold box, it includes cold box base and the cold box body of setting on the base, the cold box body is enclosed by many vertical layout's stand, carries out welded fastening through many crossbeams between this stand and the stand, this stand and crossbeam enclose into the hollow cavity chamber of the rectangular size that heat exchanger and rectifying column can be placed to an inside hollow each other to the outside welding of cavity has the cold box panel, the cold box panel is the wave unsmooth form, and its both ends are welded respectively in the stand both sides, and its crossbeam welding is in the depressed part of panel, makes the cold box become a canned type box device.
Preferably, the method comprises the following steps: the corrugated concave-convex cold box panel is 4mm thick, the corrugation depth is 50mm, and the corrugation width is 120 mm.
Preferably, the method comprises the following steps: the cold box panel is made of a carbon steel plate.
The utility model discloses an above new cold box panel wave design has reached the purpose of optimizing cold box panel structural design, has saved the material and has reduced manufacturing process to the equipment investment has been saved.
Drawings
FIG. 1 is a schematic view of a skid mounted cold box.
FIG. 2 is a schematic view of the structure of an old cold box panel.
Fig. 3 is a schematic view of a new corrugated plate cold box panel structure.
Fig. 4 is a schematic view a-a of fig. 3.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings: fig. 1 shows, a novel sled dress cold box, it includes cold box base 1 and the cold box body 2 of setting on the base, cold box body 2 is enclosed by many vertical arrangement's stand 3, carries out welded fastening through many crossbeams 4 between this stand 3 and the stand 3, this stand 3 and crossbeam 4 enclose into a hollow cuboid type hollow cavity 5 that can place heat exchanger and rectifying column of inside each other to the welding has cold box panel 6 in the outside of cavity 5.
As shown in fig. 3-4: the cold box panel 6 is in a wave shape, the two ends of the cold box panel are respectively welded on the two sides of the upright post 3, the cross beam 4 is welded on the concave part of the panel, so that the cold box becomes a sealed box device, the thickness of the wave shape cold box panel is 4mm, the corrugation depth is 50mm, the corrugation width is 120mm, and the cold box panel 6 is made of a carbon steel plate.
The utility model discloses an effect, through replacing former flattening steel sheet with corrugated steel plate and making the cold box panel usefulness, utilize corrugated steel plate intensity to be greater than flattening plate intensity's advantage, can optimize former cold box bracing of cancellation and panel strengthening rib, and can not warp after cold box panel welding accomplishes, need not carry out cold box panel levelling process, saved cold box steel structure material greatly and reduced the welding manufacturing process to the equipment investment has been reduced.
