Inner canister 20 can with outer tank 10 to be internally formed the thermal insulation spaced apart with the internal face of outer tank 10 empty Between form be configured.The inner canister 20 can be formed with film low temperature steel material.
In addition, powder isolation material 30 is filled in the adiabatic space between inner canister 20 and outer tank 10.
The powder isolation material 30 can be applicable in perlite (perlite), aeroge (aerogel), glass blister (glassbubble) any one in.
The manufacture method of the membrane pressure vessel with the composition is specifically described below.
Fig. 2 is the flow chart for roughly showing membrane pressure vessel manufacture method according to an embodiment of the invention.
First, Fig. 3 is upper nozzle and the lower part for roughly showing composition inner canister according to an embodiment of the invention The side view for the state that nozzle is fixed by fixture, Fig. 4 be roughly show to the upper nozzle of Fig. 3 and lower nozzle into Row connection is so as to manufacture the profile of the state of inner canister.
As shown in Figures 3 and 4, using fixture 25 with the state that is spaced to being formed 22 He of upper nozzle of membrane pressure vessel Lower nozzle 24 is fixed, in this condition, to being attached between upper nozzle 22 and lower nozzle 24, so as to manufacture Go out inner canister 20 (INNER TANK) S10.
In S10 steps, in the state of fixture 25 is fixed using crane 23, upper nozzle 22 and lower part are sprayed Mouth 24 is separately mounted to the both sides of fixture 25.Afterwards, with film low temperature steel material between upper nozzle 22 and lower nozzle 24 into Row connection, so as to produce inner canister 20.
Next, Fig. 5 is roughly to show that inner canister according to an embodiment of the invention is inserted and fixed in outer tank The profile of the state in portion, Fig. 6 are the lower parts for roughly showing to utilize supporting block to being connected to inner canister in the outside of the outer tank of Fig. 5 Nozzle is supported, and the profile of the state of the top progress end plate welding to outer tank.
First, as shown in Figure 5 so that the inner canister 20 of S10 steps is located at the inside of outer tank 10 and it is fixed, outer tank 10 are arranged at working space S20.
More specific detail is carried out, as shown in figure 5, outer tank 10 is fixed on ground using supporting rack 11.And utilize Crane 23 is so that inner canister 20 is located at the inside of outer tank 10.Afterwards, as shown in fig. 6, exposing to the lower part of the outside of outer tank 10 The ground of nozzle 24 is supported the weight of inner canister 20 by supporting block 40.
In S20 steps, outer tank 10 is supported on the ground using multiple supporting racks 11.
Afterwards, it is attached by welding the protrusion of pair inner canister 20 to connect with the breakthrough part of outer tank 10.It is next, sharp The weight of inner canister 20 is supported with supporting block 40, or when necessary, can be between supporting block 40 and lower nozzle 24 Reinforcing plate 28 is set, so as to carry out reinforcement operation.
Next, the upper part of outer tank 10 is attached by end plate welding, so as to complete the outer of membrane pressure vessel See.
Fig. 7 is roughly to show the inside according to an embodiment of the invention that liquid nitrogen is poured into inner canister using jet pipe Profile, Fig. 8 are the mian part profiles for roughly showing to shrink as caused by the film shape distortion of the inner canister of Fig. 7.
Next, as shown in fig. 7, in the state of the upper nozzle 22 of inner canister 20 is opened, jet pipe is set to inside simultaneously After being assembled again to upper nozzle 22, liquid nitrogen is poured into the inside of inner canister 20 by jet pipe, so that 20 thermal contraction of inner canister S30.At this time, as shown in figure 8, the outer surface part of inner canister 20 shunk.
In S30 steps, in the state of upper nozzle 22 and lower nozzle 24 are fixed on outer tank 10 by welding, inner canister 20 do not carry out thermal contraction vertically.However, inner canister 20 occurs while the shape for forming the film of inner canister 20 deforms Shrink, so as to realize the absorption of thermal stress.
Fig. 9 is roughly to show according to an embodiment of the invention powder isolation material to be flow into inner and outer tank Between profile.
Next, as shown in figure 9, powder isolation material 30 is flow into the inner canister 20 and outer tank 10 for being formed in S30 steps Between adiabatic space, adiabatic space is remained into vacuum state S40 using vacuum pump.
In S30 steps, powder isolation material can be applicable in perlite (perlite), aeroge (aerogel), glass Any one in bubble (glassbubble).
The S30 steps are realized while powder isolation material 30 is injected to be acted on using the air discharge of air pump, from And adiabatic space can become vacuum.
Figure 10 is roughly to show according to an embodiment of the invention nitrogen to be flow into cuing open for inner canister using jet pipe Face figure, Figure 11 are the mian part profiles for roughly showing to expand as caused by the film shape distortion of the inner canister of Figure 10.
Next, as shown in Figures 10 and 11, after S40 steps, high temperature nitrogen is flow into described using jet pipe The inside of tank 20, so that inner canister 20 expands S50.Here, although jet pipe is not specifically shown in attached drawing, it is set to It is identical with the mode for pouring into liquid nitrogen for being illustrated in Fig. 7, so as to inject nitrogen.
In S50 steps, 20 thermal expansion of inner canister while, pressurizes powder isolation material 30 to 10 direction of outer tank.According to This, fills up adiabatic space to 30 no gap of powder isolation material, so as to realize hard form.Thus, with regard to this implementation For the membrane pressure vessel of example, the bulbs of pressure of inner canister 20 can remaining compressive residual stress, compressive residual stress is by film Crimp shape deforms and produces.
As described above, the membrane pressure vessel of the present embodiment can be fabricated to compressive residual stress.
In other words, in the case where causing inside that liquefied substance is stored in membrane pressure vessel 100 using high pressure, Neng Gouli Pressure compensation is realized with compressive residual stress.Also, cured powder isolation material 30 enables to the height produced in inner canister 20 Pressure is swimmingly transferred to outer tank 10, and inner canister 20 can use the liquefied substance of relatively low stress storage high pressure.
By the explanation, preferred embodiments of the present invention have been disclosed for illustrative, but the present invention is not limited to this, In the range of claims and detailed description of the invention and attached drawing, can deformation implementation to be a variety of, certainly, this falls within this The scope of invention.
