Heat storage skid-mounted protective cover for pressure vessel heat preservation and manufacturing method thereof

Abstract

A thermal storage skid-mounted protective cover for pressure vessel insulation and a manufacturing method thereof, comprising a skid plate with rollers, the skid plate is provided with a connected first semi-cylindrical cover and a second semi-cylindrical cover, the first semi-circular The cylinder cover and the second semi-cylindrical cover have the same structure; the cross-section of the first semi-cylindrical cover is semicircular, and the first semi-cylindrical cover includes the first layer frame, the second layer frame and the third layer frame arranged at intervals from outside to inside A vacuum layer is formed between the frame of the first layer and the frame of the second layer, and a heat storage layer is formed between the frame of the second layer and the frame of the third layer, and heat storage materials are placed in the heat storage layer. The overall structure of the protective cover is simple, not only can play the role of heat preservation and heat storage, but also can be easily moved, transported and assembled. To a good protection effect, prolong the service life of the pressure vessel.

Description

technical field [0001] The invention relates to the field of equipment manufacturing, in particular to a heat storage skid-mounted protective cover for heat preservation of a pressure vessel and a manufacturing method thereof. Background technique [0002] In Xinjiang and other places where the temperature difference between day and night is large, the use of pressure vessels is greatly affected. The temperature is high during the day and low at night. Under the long-term alternating cold and heat, the pressure vessel will always have temperature difference stress, which makes the pressure vessel extremely vulnerable. damage, resulting in reduced lifespan. Insulation treatment of pressure vessels can greatly improve its service life, and the existing insulation methods for low-temperature vessels mainly include: vacuum powder, vacuum interlayer, polystyrene foam, polyvinyl chloride foam and other insulation materials as insulation layers . The existing heat preservation me...

AI Technical Summary

Problems solved by technology

The existing heat preservation methods basically add a layer of heat insulation layer on the outside of the pressure vessel to achieve the purpose of heat preservation, but it is inevitable that corrosion will occur during use and the insulation layer will fall off; in addition, due to the insulation layer It is directly attached to the outer surface of the pressure vessel. If it is not fully covered, it is very likely to cause uneven temperature differences in various parts of the interior, resulting in more serious temperature stress damage and failing to achieve the expected effect; in addition, solar energy has not been effectively utilized.
