Description

Technical Field

[0001] The utility model relates to a heat preservation method for equipment in the construction of a chemical plant, in particular to a special material equipment with a heat preservation structure, and belongs to the technical field of chemical equipment manufacturing. Background Art

[0002] In the construction of chemical plants, most equipment needs to be insulated to prevent a large amount of heat loss. Conventional equipment usually facilitates insulation by welding insulation nails on the equipment shell. However, for equipment made of special materials, due to the special nature of the material, it is impossible to directly weld insulation nails on the surface of the special material equipment. The traditional insulation method cannot ensure that the insulation material fits tightly on the surface of the equipment, resulting in poor insulation effect.

[0003] Currently in China, the insulation problems of special material equipment are insufficient in anti-vibration ability, unable to effectively resist vibration, and the insulation products are prone to sagging, especially when the equipment has a large taper, the effect is worse; when one end of the equipment is large and the other end is small, or the shape changes greatly, the soft and detachable insulation products are easy to slide, making it difficult to ensure the insulation effect. Utility Model Content

[0004] In view of the defects of the above-mentioned technology, the purpose of the utility model is to provide a special material equipment with an insulation structure and an insulation method. By innovatively utilizing the welding space above the equipment reinforcement ring, the problem that special material equipment cannot directly weld insulation nails on the surface is solved, thereby improving the insulation effect.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a special material equipment with a heat preservation structure, comprising: a tower device, the tower device is an integrated transition tower body with an upper cylindrical part, a middle and lower conical body and a bottom U-shaped cylinder; the outer area of ​​the middle and lower conical body is provided with a heat preservation mechanism, and the bottom end of the middle and lower conical body is supported on the bottom platform by a steel pipe bracket;

[0008] Furthermore, the heat preservation mechanism is arranged in the welding space of the tower equipment;

[0009] Furthermore, the two reinforcement rings are respectively fixedly welded to the outer wall of the cone in the lower part of the tower equipment;

[0010] Furthermore, the insulation mechanism is a double-layer plate + outer insulation nail combination, including: galvanized steel plate, polytetrafluoroethylene plate and a plurality of insulation nails; a polytetrafluoroethylene plate is arranged on the conical outer surface of the tower equipment between the two reinforcing rings, a galvanized steel plate is arranged on the outer surface of the polytetrafluoroethylene plate, and a plurality of insulation nails are arranged corresponding to the outer diameter horizontal direction of the galvanized steel plate; the insulation nails are used to fix the insulation material so that the insulation material is closely attached to the tower equipment;

[0011] In the above structure, the polytetrafluoroethylene plate is located between the galvanized steel plate and the outer surface of the cone of the tower equipment, so as to prevent the galvanized steel plate from directly contacting the outer surface of the cone of the tower equipment and play an isolation role; the polytetrafluoroethylene plate is a high temperature resistant and corrosion resistant material, which can ensure the isolation effect in a high temperature and corrosion working environment.

[0012] Furthermore, the gap between the galvanized steel plate and the outer surface of the conical shape of the tower equipment is set to 4mm-5mm;

[0013] In the above structure, the role of the reinforcement ring is to strengthen the equipment structure and make the fixation of the galvanized steel plate and the insulation nails more stable.

[0014] Furthermore, the galvanized steel plate and the reinforcement ring on the conical outer surface of the tower equipment are fixed by welding;

[0015] Furthermore, the plurality of insulation nails and the galvanized steel plate are fixed by welding;

[0016] In the above structure, the PTFE plate is placed between the galvanized steel plate and the conical outer surface of the tower equipment, and then the insulation nails are welded on the galvanized steel plate, which solves the problem that special material equipment cannot be directly welded with insulation nails. At the same time, the insulation effect is improved and it adapts to the unevenness of the equipment surface and changes in gravity.

[0017] Furthermore, the length, density and type of the insulation nails are adjusted according to actual insulation effect requirements.

[0018] The insulation method of the special material equipment of the above insulation structure in this scheme comprises the following steps:

[0019] (1) Welding galvanized steel sheet

[0020] Between the two adjacent reinforcing rings in the outer area of ​​the lower cone of the special material equipment (tower equipment), a galvanized steel plate is fixed by argon arc welding to ensure that a gap of 4mm-5mm is left between the galvanized steel plate and the outer surface of the cone of the tower equipment;

[0026] (4) Thermal insulation material bonding

[0029] The beneficial effects of the utility model are:

[0030] This solution adapts to the uneven surface of the equipment and the change of gravity: by utilizing the welding space above the reinforcement ring and welding the galvanized steel plate, the problem that the insulation nails cannot be directly welded on the surface of the special material equipment is overcome; this method effectively solves the problem of the uneven surface of the special material equipment and the influence of gravity, ensuring that the insulation material fits tightly on the surface of the equipment;
