Detachable tube shell composite heat preservation and cold preservation device

technical field

The utility model relates to a heat preservation device in an oil field, in particular to a detachable tube-shell composite heat preservation and cold preservation device.

Background technique

Insulation includes heat and cold. Thermal insulation is a technological measure taken to reduce the heat transfer from the equipment and pipeline body to the outside or the external heat to the equipment and pipeline body. Equipment and pipeline heat preservation and cold preservation are widely used in liquid and gas transportation pipe networks. In heat preservation and cold preservation conveying equipment and pipelines, heat preservation and cold preservation, especially high temperature and low temperature equipment and pipeline heat preservation and cold preservation, are a very important link. The success of this link Whether it is directly related to whether the equipment and pipeline can be put into use normally.

At present, in the selection of thermal insulation materials for industrial equipment and pipelines, rock wool and polyurethane shells are usually used for thermal insulation and cold insulation, but generally polyurethane shells are composed of two half-shells of a certain length, and the inner surface of the shell formed and the Or the conveying pipeline is in surface contact, the heat dissipation area is large, and the thermal insulation effect is not good. To achieve a certain thermal insulation effect, the thickness of the pipe shell must be increased, which not only brings inconvenience to the construction, but also increases the construction cost. Moreover, the joints between adjacent polyurethane shells are not sufficiently sealed, which seriously affects the thermal insulation effect of equipment and pipelines.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the existing rock wool and polyurethane shell inner surface in the background technology and the contact heat dissipation area of the equipment and the conveying pipeline surface and the insufficient sealing of the joints between adjacent rock wool and polyurethane shells. In order to solve the problem of poor heat preservation and cold preservation effect, a detachable tubular shell composite thermal insulation and cold preservation device is provided. The detachable tubular shell composite thermal insulation and cold preservation device can reduce the contact area between the inner surface of the heat preservation and cold preservation tubular shell, equipment and conveying pipelines, Strengthen the sealing of the joints between adjacent thermal insulation and cold insulation tube shells, and the thermal insulation effect is good.

The utility model can solve the problem through the following technical solutions: the detachable equipment shell composite thermal insulation and cold preservation device includes equipment, pipelines, and an outer shell, and the exterior of the pipeline is coated with a thermal insulation and cold insulation layer and a coating layer, An airtight layer; an outer casing is set outside the airtight layer, and a thermal insulation cavity is formed between the airtight layer and the outer casing, and a number of semicircular reinforcing support rings are fixed in the thermal insulation cavity; the outer casing includes an upper shell and a lower The tube shell, the upper tube shell and the lower tube shell are connected by a square groove.

Compared with the above-mentioned background technology, the utility model has the following beneficial effects: the detachable tubular shell composite thermal insulation and cold preservation device adopts the above-mentioned structure, and the reinforced support ring is semicircular, which reduces the inner surface of the thermal insulation tubular shell and the equipment, and the delivery pipeline. The contact area; the intermediate layer between the airtight layer and the outer casing of the equipment and the pipeline is a plurality of thermal insulation chambers or cold insulation chambers, so that the air is relatively static in the cavity and reduces energy transfer; the upper and lower casings pass through square Groove connection, the adjacent outer casings are connected by a sealing joint, one side of the sealing joint is sealed with high-temperature or low-temperature-resistant glue, and the other side is welded and sealed by modified plastic, which strengthens the connection between adjacent heat-preservation and cold-preservation shells The seal at the place has good heat preservation effect.

The utility model will be further described below in conjunction with accompanying drawing:

As shown in accompanying drawings 1 and 2, the detachable tube-shell composite heat preservation and cold preservation device includes equipment, a conveying pipeline 1, and an outer shell. An airtight layer 4, an outer casing is sheathed outside the airtight layer 4, and a thermal insulation chamber 5 is formed between the airtight layer 4 and the outer casing, and a number of semicircular reinforcing support rings 8 are fixed in the thermal insulation chamber 5, and the adjacent The distance between the two reinforced support rings 8 is 25cm; the outer casing includes an upper shell 7 and a lower shell 6, and the upper shell 7 and the lower shell 6 are connected by a square groove, as shown in Figure 3; The adjacent outer casings are connected by a sealing joint 9, one side of the sealing joint 9 is sealed with high-temperature-resistant or low-temperature-resistant glue, and the other side is welded and sealed with modified plastic; the coating layer 3 is a polymer composite fiber material.

In the detachable tubular shell composite heat preservation and cold preservation device, the heat preservation and cold preservation chamber keeps the air relatively static in the cavity, reducing energy transmission, and the reinforcing support ring is semicircular in it, which reduces the distance between the inner surface of the heat preservation pipe shell and the equipment and conveying pipes. Contact area; the upper shell and the lower shell are connected by a square groove, and the adjacent outer shells are connected by a sealing joint. One side of the sealing joint is sealed with high-temperature or low-temperature-resistant glue, and the other side is a modified The plastic welding seal strengthens the sealing of the joints between the adjacent heat preservation and cold preservation tube shells, so that the heat preservation and cold preservation effect of equipment and conveying pipelines is better.
