Heat accumulating type skid-mounted protection cover for heat insulation of pressure vessel and making method of heat accumulating type skid-mounted protection cover

Abstract

The invention discloses a heat accumulating type skid-mounted protection cover for the heat insulation of a pressure vessel and a making method of the heat accumulating type skid-mounted protection cover. The heat accumulating type skid-mounted protection cover comprises a skid plate with rollers, wherein a first semi-cylindrical cover and a second semi-cylindrical cover which are connected are arranged on the skid plate, and the structure of the first semi-cylindrical cover is the same as that of the second semi-cylindrical cover; the cross section of the first semi-cylindrical cover is semicircular; the first semi-cylindrical cover comprises a first layer frame, a second layer frame and a third layer frame which are arranged at intervals from outside to inside; a vacuum layer is formed between the first layer frame and the second layer frame; a heat accumulating layer is formed between the second layer frame and the third layer frame; and heat accumulating materials are placed in the heat accumulating layer. The protection cover disclosed by the invention is simple in overall structure; the protection cover not only can have the effects of heat insulation and heat accumulation, but also can be convenient for movement, transport and assembly; and the heat accumulating type skid-mounted protection cover for the heat insulation of the pressure vessel can have good protective effects in places with big diurnal temperature difference, so that the service life of the pressure vessel can be prolonged.

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.
