Description
Technical field
The utility model relates to the spiral vaporizer of a kind of LNG, is specially adapted to the clean energy vehicle needing to use large vaporization capacity vaporizer.
Background technique
Along with LNG Liquefied natural gas becomes the main high-efficiency cleaning energy of China, all kinds vehicle is more and more uses LNG Liquefied natural gas, and the core process equipment that LNG Liquefied natural gas is gaseous state by liquid conversion is vaporizer.Whether up to standard the engine performance of vehicle is, relevant with the vaporization capacity of vaporizer.These type of large vehicles such as especially long-distance big bus, heavy truck, require that the vaporization capacity of vaporizer is greater than ordinary vehicle type automobile.Because vehicle limit, install the length spatial constraints of vaporizer vaporizer size, make pitch larger, the total length of internal spiral gasifying pipe is less, and the total length of spiral gasification tube is then directly proportional to vaporization capacity.Because manufacturing process and material limit, the pitch of spiral gasification tube is generally 2 times of spiral gasification tube diameter of steel tube.In limited installation space, these all limit the increase of vaporizer vaporization capacity.
Model utility content
The utility model aims to provide the spiral vaporizer of a kind of LNG, and this vaporizer, under the constant prerequisite of vaporizer size, makes the total length of inner helix pipe increase, can provide enough heat exchange areas, significantly improve the vaporization capacity of vaporizer.
To achieve these goals, the technological scheme that the utility model adopts is:
The spiral vaporizer of a kind of LNG, comprises the vaporizer shell primarily of right baffle-plate, vaporizer cylindrical shell and right baffle plate composition, is provided with cooling system in this vaporizer shell; Its structural feature is, is provided with spiral helicine outer ring gasifying pipe and is set in the spiral helicine middle gasifying pipe in the gasifying pipe of outer ring in described vaporizer shell; The import of described outer ring gasifying pipe is directly communicated with the import of described middle gasifying pipe, and the air outlet of described outer ring gasifying pipe is directly communicated with the air outlet of described middle gasifying pipe.
Thus, gasifying pipe is divided into outer ring and mesosphere two groups, adds heat exchange area, thus drastically increases the vaporization capacity of gasifying pipe.
According to embodiment of the present utility model, can also do further to optimize to the utility model, the technological scheme below for being formed after optimization:
In order to improve the vaporization ability of outer ring gasifying pipe further, described outer ring gasifying pipe is that many spiral gasifying pipes form according to Hand of spiral rotation set; Each spiral gasifying pipe internal diameter, external diameter are all identical with pitch.Thus, many spiral gasifying pipes are mutually nested, add heat exchange area, thus improve the vaporization ability of outer ring gasifying pipe.
In order to improve the vaporization ability of middle gasifying pipe further, described middle gasifying pipe is that many spiral gasifying pipes form according to Hand of spiral rotation set; Each spiral gasifying pipe internal diameter, external diameter are all identical with pitch.Thus, many spiral gasifying pipes are mutually nested, add heat exchange area, thus improve the vaporization ability of middle gasifying pipe.
As a kind of structural type, described cooling system comprises the water pipe adapter being arranged on vaporizer cylindrical shell top, and this water pipe adapter is divided into cooling water inlet and hot water outlet, and described cooling water inlet and hot water outlet are communicated with carburettor barrel intracoelomic cavity respectively.
Conveniently discharge condensed water, described vaporizer cylinder body bottom is provided with draining spiral shell seat and blocking.
Preferably, the import of described outer ring gasifying pipe is all directly communicated with the joint be arranged on right baffle-plate with the import of described middle gasifying pipe; The air outlet of described outer ring gasifying pipe is all directly communicated with the joint be arranged on right baffle plate with the air outlet of described middle gasifying pipe.
Compared with prior art, the beneficial effects of the utility model are: carburettor design of the present utility model is reasonable, and vaporization efficency is high, and floor space is little, and novel structure is compact, manufacture simple.And can according to the vaporization capacity of required vaporizer, calculate heat exchange area, change pitch and the screw diameter of outer ring gasifying pipe and middle gasifying pipe, different Combination Design is carried out to spiral gasification tube, meet the requirement of different motor property indices, Security, working efficiency are all ideal.
Below in conjunction with drawings and Examples, the utility model is further elaborated.

Embodiment
A kind of LNG tri-manages spiral vaporizer, as illustrated in fig. 1 and 2, comprises right baffle-plate 1, water pipe adapter 2, joint 3, middle gasifying pipe 4, outer ring gasifying pipe 5, draining spiral shell seat 6, blocking 7, vaporizer cylindrical shell 8, right baffle plate 9.During assembling, as shown in Figure 6, according to volute direction rotation set together, middle gasifying pipe 4 two ends and joint 3 weld in the middle of the outer ring gasifying pipe 5 together with rear insertion rotation set two pieces outer ring gasifying pipe 5, and two pieces outer ring gasifying pipe 5 welds together by the side opening recycling two end connectors 3; Welded with right baffle-plate 1 by joint 3, weld with right baffle-plate 1 after vaporizer cylindrical shell 8 is inserted in gasifying pipe.Right baffle plate 9 welds with joint 3, vaporizer cylindrical shell 8 more successively, then on vaporizer cylindrical shell 8, welds inlet joint 2, spiral shell seat 6 respectively, finally blocks 7 by screw thread precession spiral shell seat 6.
When straight tube manufactures volute, the less manufacture of pitch is more difficult, and the pitch of spiral gasification tube is generally 2 times of spiral gasification tube diameter of steel tube.Two pieces outer ring gasifying pipe 5 is welded on joint 3 according to volute direction rotation set together, be equivalent to the single-screw pipe that a pitch is former 0.5 times of pitch, pitch size and exchange capability of heat are inversely proportional to, add middle gasifying pipe 4, liquid gas flows into from vaporizer one end connector 3, and parallel shunt gasifies in three volutes, the hot and cold water passed in and out by water pipe adapter 2, heat exchange area significantly improves, and vaporization capacity significantly increases.
The content that above-described embodiment is illustrated should be understood to these embodiments only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen into the application's claims limited range.
