Description
Technical field
The invention belongs to tank body manufacturing technology field in cryogenic liquide storage equipment, specifically provide outer tank body bushing device and suit technique in a kind of low-temperature (low temperature) vessel.
Background technique
Particularly LNG is as a kind of clean, efficient, convenient, safe energy for cryogenic liquide, and the features such as, pollution high with its calorific value is few become high-grade energy, and its storage equipment (storage tank, conveying semi-trailer, tank container) has the wide market demand.
Cryogenic liquide conveying arrangement is formed by interior outer tank body fit, outer tank body inside uses stiffening ring reinforcement, when outer tank body has accomplished gauge allowed band maximum value, in order to increase economic efficiency and unit single transport capacity, can only mezzanine space be reduced, pursue the maximization of interior tank volume.Thus give low temperature insulation container made manufacturing process, especially, outer tank body fit brings challenge.
The bushing device of current use is trapped orbit, and substantially can be divided three classes: the first, the monolateral gap of mezzanine space is large, directly on outer tank body inner stiffener ring, installs trapped orbit additional; The second, outer tank body inner stiffener ring disconnects at track place, the reserved position installing trapped orbit additional; 3rd, in stiffening ring clearance space, be fixed track.These adopt the cover tank mode of trapped orbit to there is following shortcoming: cause waste, and trapped orbit is only used to tank body suit technique use, and without other purposes, but it is as a product part, causes waste of raw materials and cost of transportation to increase; Sacrifice load-carrying, trapped orbit can increase mezzanine space gap, not only can increase product deadweight, and can reduce interior tank volume, thus sacrifice tank body load-carrying, increase cost of transportation; Cover tank difficulty, due to tank body rigidity, at stiffening ring gap, tank body easily produces serious distortion, even occurs straight section, and tank body circularity is difficult to ensure, is not only difficult to ensure technical requirements, and interior outer tank body can be caused to be set with difficulty; Clean difficulty, stiffening ring and outer tank adopt welding connecting mode, and welding slag etc. increase the clean difficulty of interlayer, even directly can affect layer vacuum index, extend pump-down time.
Summary of the invention
