Insulation board for heat insulation and cold preservation of liquefied gas cryogenic storage tank

Abstract

A thermal-insulating plate for thermal insulation and cold insulation of a liquefied gas low-temperature storage tank comprises a first thermal-insulating layer, a second thermal-insulating layer and a third thermal-insulating layer which are arranged sequentially, wherein the three thermal-insulating layers are arranged in a staggered manner; joggle joint structures are respectively formed on four side surfaces of the thermal-insulating plate; the adjacent thermal-insulating layers are adhered by low-temperature glue water and then are connected to one another; and an outer protecting layer is arranged on the upper surface of the first thermal-insulating layer. The second thermal-insulating layer extends to a first side and a second side relative to a first protecting layer, and buffering thermal-insulating layers are respectively arranged on the bottom surface and two recessed side surfaces of the extension part. The third thermal-insulating layer extends to a third side and a fourth side relative to the first protecting layer and the second thermal-insulating layer, a fixing plate is mounted on the extension part in an embedded manner, a mounting hole which runs through in the vertical direction is further formed in the extension part, the fixing plate penetrates through the mounting hole, and buffering thermal-insulating layers are respectively arranged on two side surfaces of the extension part. The thermal-insulating plate has the advantages of wide using range, safety and reliability, excellent air permeability performance, mounting stability, and convenience in safe maintenance.

Description

technical field [0001] The invention relates to thermal insulation materials, in particular to a thermal insulation board used for heat insulation and cold preservation of liquefied gas cryogenic storage tanks. Background technique [0002] The heat insulation and cold insulation panels of liquefied gas cryogenic storage tanks currently on the market have the following problems: [0003] (1) The strength of the insulation board is insufficient, and it is easy to deform and break; [0004] (2) The assembly structure of the insulation board is not tight; [0005] (3) The connection between the insulation board and the storage tank is not stable. [0006] Adhesives are currently used on the market to bond insulation boards to insulation boards, and insulation boards to storage tanks. Since the bonding performance is affected by factors such as humidity, temperature, and construction technology, when the above factors do not meet the relevant requirements, that is, Adhesive f...

Problems solved by technology

[0003] (1) The strength of the insulation board is insufficient, and it is easy to deform and break;

[0004] (2) The assembly structure of the insulation board is not tight;

[0005] (3) The connection between the insulation board and the storage tank is not stable

[0006] Adhesives are currently used on the market to bond insulation boards to insulation boards, and insulation boards to storage tanks. Since the bonding performance is affected by factors such as humidity, temperature, and construction technology, when the above factors do not meet the relevant requirements, that is, Bond failure will occur, resulting in the above problems
