Description
Technical field
The utility model relates to chemical technology field, particularly relates to the corrosion-resistant steam jacket thermal insulation pipe of a kind of Molten sulphur conveying.
Background technique
Thermal insulation pipe is the abbreviation of insulated piping, is mainly used in the conveying of liquid, gas and other media, in the adiabatic heat-insulation engineering of the pipelines such as oil, chemical industry, space flight, military affairs, central heat supply, central air-conditioner, municipal administration.Traditional thermal insulation pipe mainly through adding heat-insulating layer to realize the function of material insulation conveying in pipeline outside carbon steel piping wall.But in Molten sulphur course of conveying, owing to removing clean hydrogen sulfide containing end in Molten sulphur, hydrogen sulfide is to carbon steel pipe line seriously corroded, often cause conveyance conduit corrosion failure, jacket steam seals in molten sulfur pipeline and causes left alone without help car, sick simultaneously because corrosion causes the blocking of spray sulphur rifle to be forced to stop, have a strong impact on manufacturing efficiency.For solving the problem, spy develops the corrosion-resistant steam jacket thermal insulation pipe of a kind of Molten sulphur conveying.
Model utility content
The purpose of this utility model is to provide the corrosion-resistant steam jacket thermal insulation pipe of a kind of Molten sulphur conveying.
The technical solution of the utility model is: the corrosion-resistant steam jacket thermal insulation pipe of a kind of Molten sulphur conveying, by main line, chuck pipeline, thermal insulation layer and protective layer composition, described chuck pipeline be positioned at main line outer wall place and with main line for being fixedly connected with, described thermal insulation layer be positioned at chuck pipeline outer wall place and with chuck pipeline for being fixedly connected with, described protective layer be positioned at thermal insulation layer outer wall place and with thermal insulation layer for being fixedly connected with, described chuck pipeline is also provided with inlet and exhaust port, described inlet is positioned at one end of chuck pipeline, described inlet runs through the inner space of thermal insulation layer and protective layer and chuck pipeline, described exhaust port is positioned at the other end of chuck pipeline, described exhaust port runs through the inner space of thermal insulation layer and protective layer and chuck pipeline.
Further, leakage alarm line is also provided with between described thermal insulation layer and chuck pipeline.

Embodiment
Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.
The corrosion-resistant steam jacket thermal insulation pipe of a kind of Molten sulphur conveying as shown in Figure 1, by main line 1, chuck pipeline 2, thermal insulation layer 5 and protective layer 6 form, described chuck pipeline 2 be positioned at main line 1 outer wall place and with main line 1 for being fixedly connected with, described thermal insulation layer 5 be positioned at chuck pipeline 2 outer wall place and with chuck pipeline 2 for being fixedly connected with, described protective layer 6 be positioned at thermal insulation layer 5 outer wall place and with thermal insulation layer 5 for being fixedly connected with, described chuck pipeline 2 is also provided with inlet 3 and exhaust port 4, described inlet 3 is positioned at one end of chuck pipeline 2, described inlet 3 runs through the inner space of thermal insulation layer 5 and protective layer 6 and chuck pipeline 2, described exhaust port 4 is positioned at the other end of chuck pipeline 2, described exhaust port 4 runs through the inner space of thermal insulation layer 5 and protective layer 6 and chuck pipeline 2.
Leakage alarm line is also provided with between described thermal insulation layer 5 and chuck pipeline 2.When seepage occurs in chuck pipeline 2 somewhere, by the conduction of alarm line, just can report in dedicated test instrument and warn and demonstrate the size of accurate location and the leak magnitude leaked, to notify that maintainer processes rapidly the pipeline section leaked.
Described main line 1 is 304 stainless steels.The material in main line 1 (hydrogen sulfide) is avoided to cause corrosion to main line 1.
Described chuck pipeline 2 is carbon steel material.Because chuck pipeline 2 does not directly contact with transportation of substances (hydrogen sulfide), carbon steel material is adopted effectively to reduce costs.
Described thermal insulation layer 5 is RPUF.Effectively can reduce heat loss, energy saving.
Described protective layer 6 is high density polyethylene (HDPE) or glass fibre reinforced plastics.Can effectively improve the anticorrosion of pipeline surface and insulating property, increase pipeline working life.
Working method: the conveying of this Molten sulphur is mainly used in the conveying of the material that Molten sulphur etc. needs insulation to carry with corrosion-resistant steam jacket thermal insulation pipe.By adopting 304 stainless steels as main line 1; the corrosion resistance of effective raising pipeline; by at the additional mounting clip sleeve pipeline 2 of pipeline; be injected into along inlet 3 in the inner chamber of chuck pipeline 2 by steam, ensure the temperature of pipeline, condensed water is discharged along exhaust port 4; increase thermal insulation layer 5 on surface and reduce heat loss; increase protective layer 6 and improve pipeline working life, leakage alarm line is set, easy access.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
