Abstract
The utility model discloses a plug used for quick plugging of a graphite shell and tube heat exchanger. The plug is characterized in that the plug comprises a housing (1) and an acid-proof rubber sleeve (2), wherein, the acid-proof rubber sleeve (2) is lined on the outer surface of the housing (1); an expansion bolt (3) passes through the housing (1) and is fixed to the housing (1) through a nut (4); and a gasket (5) is arranged between the nut (4) and the housing (1). The utility model has the advantages of quick plugging, convenient use, simple structure and low cost.
Description
Technical field
The utility model belongs to the leakage stopping technology field, relates in particular to a kind of plug.
Background technology
Tubular heat exchanger is one of visual plant in the heat transfer process.In the phosphoric acid by wet process device of China, in order to prevent the corrosion of phosphoric acid, phosphoric acid is carried dense used heat exchanger and is all adopted the graphite tubular heat exchanger.In actual applications, because the phosphoric acid by wet process impurity content is big, can produce a large amount of postprecipitation salt in the Phosphoric Acid Concentration process, cause fouling easily in the heat exchanger tube, frequent cleaning and clean heat exchanger is broken heat exchanger tube easily and is leaked acid.Traditional heat exchanger blocking method is to add curing agent with graphite powder, because easier the coming off of graphite powder that newly adds, service life is not long, again because graphite powder needs the time longer when solidifying, therefore have a strong impact on the driving rate of device concentration systems, the system production capacity of making can not get good performance.
At present, do not see report as yet at the aspect of phosphoric acid by wet process concentration systems graphite heat exchanger tubulation choked technique.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned shortcoming and provide a kind of can fast blockage, easy to use, the plug that is used for graphite tubular heat exchanger fast blockage simple in structure, that cost is low.
The plug that is used for graphite tubular heat exchanger fast blockage of the present utility model comprises housing, acid-resisting rubber cover, and the acid-resisting rubber cover is lining in housing outer surface, and expansion bolt passes housing and is fixed on the housing with nut, is provided with pad between nut and housing.
Method of the present utility model compared with prior art, as can be known from the above technical solutions, after the graphite tubular heat exchanger leaks acid, quick plug is put into heat exchanger tube, expansion bolt makes the acid-resisting rubber cover of housing outer lining closely contact with heat exchanger wall, the place seals at heat exchanger tube sheet, prevents sour seepage.Be provided with pad between nut and housing and make the plug better tightness.What housing adopted is stainless steel and acid-resisting rubber cover, can effectively prolong the service life of plug, thereby prolong the service life of tubulation, for the lifting of plant capacity provides safeguard.Thereby have can fast blockage, easy to use, characteristics simple in structure, that cost is low.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Mark among the figure:
1, housing; 2, acid-resisting rubber cover; 3, expansion bolt; 4, nut; 5, pad.
The specific embodiment
Referring to accompanying drawing, the plug that is used for graphite tubular heat exchanger fast blockage comprises housing 1, acid-resisting rubber cover 2, and acid-resisting rubber cover 2 is lining in housing 1 outer surface, expansion bolt 3 passes housing 1 usefulness nut 4 and is fixed on the housing 1, and 1 of nut 4 and housing are provided with pad 5.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
