Description
Technical field
The present invention relates to a kind of auxiliary device of making the low-temperature liquefaction natural gas tank, particularly a kind of low-temperature liquefaction natural gas tank cover is shelved.
Background technique
Rock gas is a kind of energy of good combination property.The natural gas volume of equal in quality is 600 times of LNG Liquefied natural gas volume.For convenient transportation and storage, make LNG Liquefied natural gas to rock gas.
LNG Liquefied natural gas (LNG) is to adopt cryogenics, the liquified natural gas that makes with natural gas under certain pressure.
During with the vehicle transport LNG Liquefied natural gas, be with low-temperature liquefaction natural gas tank splendid attire LNG Liquefied natural gas.The low-temperature liquefaction natural gas tank will guarantee the temperature of LNG Liquefied natural gas in tank at subzero 162 ℃ ~ subzero 196 ℃, and pressure is at 0.65Mpa ~ 1.59Mpa.
In order to improve conveying efficiency, reduce cost of transportation, under the prerequisite that meets the communications and transportation standard, the low-temperature liquefaction natural gas tank is large as much as possible, and the length of low-temperature liquefaction natural gas tank can reach 12 meters at present, and diameter can reach 2.5 meters, and volume can reach more than 50 cubic metre.
Vehicle transport has interior tank body and the outer tank body that is nested together with the low-temperature liquefaction natural gas tank, interior tank body and outer tank body have cylindrical drum, and there is ellipsoidal head at the two ends of cylindrical shell.Gapped between interior tank body and outer tank body, the outside of interior tank body is coated with flexible aluminium foil thermal insulation quilt, the cylindrical shell inboard of outer tank body is evenly equipped with the ring stiffening rib, during low-temperature liquefaction natural gas tank splendid attire LNG Liquefied natural gas, gap between interior tank body and outer tank body will be evacuated, the gap of high vacuum and aluminium foil thermal insulation quilt make the LNG Liquefied natural gas in the low-temperature liquefaction natural gas tank be in adiabatic state, and the LNG Liquefied natural gas of keeping in the low-temperature liquefaction natural gas tank is in lower temperature.
When making the low-temperature liquefaction natural gas tank, first produce the cylindrical shell of interior tank body and outer tank body with steel plate, then coat flexible aluminium foil thermal insulation quilt in the outside of interior tank body, the ring of the inboard of tank body cylindrical shell welding outside stiffening rib, again the cylindrical shell of outer tank body is sleeved on the outside of interior tank body from an end of interior tank body, keep certain gap between tank body and outer tank body in the suit relief, then end socket is welded at the two ends of tank body cylindrical shell outside.
Because the length of interior tank body and outer tank body is longer, diameter is larger, tank skin is relatively thin, in during making, tank body and outer tank body cylindrical shell axially and radially has certain form and position tolerance, and during suit, outer tank body cylindrical shell has certain distortion, also there are form and position tolerance in the track of track vehicle and inner canister body axis, in order to improve the actual volume of low-temperature liquefaction natural gas tank, the gap between interior tank body and outer tank body is very little, and the inboard of outer tank body cylindrical shell is welded with ring section bar stiffening rib.In the suit operation process, the axis of outer tank body cylindrical shell will keep axis with interior tank body on same straight line, and the gap in guaranteeing between tank body and outer tank body is even, and the section bar stiffening rib never
Can touch the aluminium foil thermal insulation quilt of the external side flexibility of inner canister.Because above-mentioned reason, outside the inner canister extracorporeal set during tank body cylindrical shell, the axis of outer tank body cylindrical shell departs from the axis of interior tank body sometimes, often need to from upper and lower to, left and right sides to axial angle on adjust the orientation of tank body cylindrical shell, avoid the stiffening rib on outer tank body cylindrical shell inner circumference to touch the flexible aluminium foil thermal insulation quilt that the external side of inner canister coats, in the operation of reality suit, it is a very difficult operation that the barrel jacket of outer tank body is contained in the external side of inner canister.
In prior art, the barrel jacket of outer tank body is not contained in the isolated plant of the external side of inner canister, to use track vehicle when the suit operation, the assistant tool that crane etc. are general and device, track vehicle has the rectangle frame of level, there is rail wheel the vehicle frame below, and there is respectively the carrier roller frame of outer tank body cylindrical shell at the front portion above vehicle frame, middle part and rear portion.During the suit operation, outer tank body cylindrical shell is placed on the carrier roller frame at vehicle frame upper forepart, middle part and rear portion, track vehicle is slowly walking vertically, driving outer tank body cylindrical shell moves, external the inner canister that outer tank body cylindrical shell is sleeved on horizontal positioned gradually from an end of interior tank body, during suit, should keep the axis of the axis of outer tank body cylindrical shell and interior tank body on same straight line, when deviation occurring between the axis of the axis of outer tank body cylindrical shell and interior tank body, with the orientation of the outer tank body cylindrical shell of crane adjustment.Outer tank body cylindrical shell and the interior tank body of suit low-temperature liquefaction natural gas tank like this, inefficiency, operation quality is poor, labor intensity is large.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind of high working efficiency, operation quality is good, labor intensity is little low-temperature liquefaction natural gas tank cover is shelved.
The present invention is achieved using the following method.
