Abstract
The utility model relates to a tool for preparing a demister, which is composed of two semicircle-shaped metal hoops, wherein through holes for fastening bolts are arranged at the end parts of the metal hoops to form a circular hoop with the diameter which is greater than that of the demister. Particularly, the tool is suitable for the demister made of an HDPE (High-Density Poly Ethylene) material. The repairing tool can repair the demister, can effectively repair the problem of damaging a framework of the demister in a transportation process, and can save a large amount of cost.
Description
Technical field
The utility model relates to a kind of instrument of repairing demister, especially for the repair outfit of the demister of HDPE material.
Background technology
The demister that existing sulfuric acid industry is used, its shape such as latticed frame structure are rolled into cylindricly, and interior housing material is high density polyethylene (HDPE) (is called for short HDPE), is the glass fibre of special substance between the interior housing.The main application of demister is the salt acid mist of removing in the gas, and the mixing droplet of saliferous acid mist.
The housing of demister adopts the wire of Hastelloy, and the two ends of alloying metal bar are fastened on the outer the widest part of framework separately, connects to fasten.
Because the demister framework is thinner.And the characteristic that the HDPE material is intrinsic, not enough like hardness, more crisp, through transportation for a long time, cause the alloying metal bar the wherein drawing crack on one side or the equal drawing crack in both sides of the framework that connects.Housing junction cracking, even fracture.
The way of conventional repairing demister is; Utilize the shape of demister cylinder; Directly tie the fracture position of demister housing junction with two strands of hawser; Strain two ropes simultaneously, two place's housing the widest part of the required connection of bonding jumper that connects housing are run into together. upward get final product with the bonding jumper connection.But this kind method only is suitable for the demister of comparatively firm non-HDPE material, for, the demister of HDPE material, then this conventional method is infeasible, and promptly because the HDPE material is more crisp, and hardness is not strong, the tension force that can bear is limited.Directly tie the fracture position of demister housing junction, can squeeze the housing at the rope place of tying tight and split, also might be extruded into inside casing simultaneously, can cause the damage of demister like this with two strand.
Summary of the invention
The purpose of the utility model provides a kind of instrument of repairing demister, repairs the technical problem of the demister framework damage that brings because of transportation.
Concrete technical scheme is:
A kind of instrument of repairing demister is that two semicircle arcuation ferrules are formed, and is provided with the through hole that supplies bolted in the ferrule end, constitutes the circular, hoop of diameter greater than demister.
Further, the demister of being repaired is the demister of high density polyethylene (HDPE) material framework.
Repair demister with this repair outfit, can effectively repair the problem of damaging because of the demister framework that brings in the transportation, can save a large amount of costs.
Description of drawings
Fig. 1 is the schematic cross-section that the utility model is repaired HDPE material demister.
Among the figure: the 1-ferrule; The 2-demister; The 3-through hole.
The specific embodiment
As shown in Figure 1, be the sketch map that the utility model is repaired HDPE material demister.Repair outfit is that two semicircle arcuations ferrule 1 is formed, and is provided with the through hole 3 that supplies bolted in the ferrule end, constitutes the circular, hoop of diameter greater than demister.In the repair procedures, the ferrule of two semicircle arcuations is linked together with bolt, circle is lived demister 2.Adjust fastening degree through the degree of tightness of adjustment bolt then.In addition, be close to demister and be covered with the clean metal level of one deck, the one, for fear of the demister of making dirty, will influence demist efficient to a great extent because in a single day the glass fibre of demister is stained with the water-fast impurity of solid; The 2nd, in order further to protect the demister framework, because the whole relatively demister of the frame of demister is thinner, in repairing fastening process, the framework at fastening place ruptures easily.Therefore, be employed in the method that the fastening place of demister is covered with sheet metal, not only enlarge the tension force area; When avoiding fastening to the damage of demister framework; And when repairing, be convenient to operation, ferrule is mobile more convenient during repairing, can directly slide along metal level to get final product.
Two frames of outermost of demister housing are fastened to a time-out, are to lean on the wire of Hastelloy to fasten, because the demister glass fibre is tightr; For avoiding that frame is fastened to a time-out; The wire of Hastelloy can't pierce into the demister fiber, when fastening, is not connecting Hastelloy frame wiry place complete; Add the clean narrow sheet metal of lastblock, so that the later stage is inserted the Hastelloy wire of connection from here.
Like this, the degree of tightness through adjustment junction bolt can be tightened to outermost two place's frames of demister housing each other and be close to, and inserts the Hastelloy wire from the good narrow sheet metal of prior pad again, tightens wire with instrument, and the repairing is here just accomplished.
Because the standard demister length that is applied to chlor-alkali and PVC field is generally 12 meters, a place fastening good after, can not dismantle all the things rapidly and change a place; Want earlier temporary transient maintenance the around the housing of repairing; This moment, available two hawser were tied up in the outside of the housing of repairing, so that the moving metal hoop because element has been secured in safe range to a certain degree; The metal level that coats is motionless, then ferrule is slided toward unrepaired direction along metal skin gradually.Incremental in this way, up to repairing whole demister housing, the metal level of ferrule and coating is dismantled to get final product.
Repair the demister of HDPE material with this repair outfit; Can effectively repair the problem of damaging because of the demister framework that brings in the transportation; Can save a large amount of costs; More a lot of than independent with the fastening demister safety of hawser, simple with hawser probably the demister housing damage more serious.The repair outfit of the utility model has solved the problem of HDPE and the damage of similar material demister framework thereof, and safety coefficient is high.
