Abstract
A liquefied natural gas gasification device includes a liquid storage unit, a gasification pressure regulating unit and an unloading liquid filling port; the liquid storage unit includes a liquid storage tank, pressure boost gasified, a boost valve and a safety valve. The unloading liquid filling port is respectively connected with the inlet of the liquid storage tank and that of the boost gasified by pipes; the outlet of the boost gasified is connected with the safety valve by the boost valve; the outlet of the liquid storage tank is connected with the inlet of the gasification pressure regulating unit; the lower part of the liquid storage tank of the liquid storage unit is connected with a liquid filling port; a throttling and pressure relief device is connected between the outlet of boost valve and that of the liquid storage tank; the device is serially connected with a pressure relief valve, a damper and a pipe. With the above technical proposal, the throttling and pressure relief device can open the circuit when the pressure does not reach the evacuating pressure relief valve, so as to relieve the gaseous LNG to the gasification pressure regulating unit, without the need of evacuation and pressure relief, which saves the raw material. A liquid filling port added to the liquid storage tank is to fill liquid to the Dewar bottle for transfer. The integrated pry block structure provides great convenience for construction of the gasification station, reduces the area and the investment cost.
Description
Technical field
The utility model relates to a kind of liquefied natural gas vaporization device.
Background technology
Existing liquefied natural gas (LNG) vapourizing unit (station) mainly contains the two large divisions, be liquid storage unit and vaporization pressure regulation unit, the liquid storage unit mainly is made up of fluid reservoir, it is connected with the implementation of port of unloading, safety-pressure release assembly and outlet, this outlet is delivered to vaporization pressure regulation unit with LNG and supply with user's use after the vaporization pressure regulation.The shortcoming of existing this LNG liquefying plant is: when the pressure of fluid reservoir surpassed a setting value, its safety-pressure release assembly was opened and is outwards discharged natural gas to reduce pressure, and this can waste a large amount of LNG, also pollutes the environment; The undirected outer interface that fills bottle of fluid reservoir can not satisfy the demand to other small-scale supply station transhipment; The mode of surface construction is adopted at existing LNG vaporization station basically, and each discrete equipment of being about to is installed in respectively on the special ground, and complex process is in large scale, has wasted a large amount of soils and fund.
Summary of the invention
The purpose of this utility model just provides a kind of liquefied natural gas vaporization device that does not need the emptying release of pressure, is provided with implementation of port and integrated sled blocking.
The technical solution of the utility model is: comprise liquid storage unit, vaporization pressure regulation unit and the implementation of port of unloading, the liquid storage unit comprises fluid reservoir, boosting vaporizer, back-up valve and safety valve, the implementation of port of unloading is connected with the inlet of fluid reservoir and the inlet of boosting vaporizer by pipeline respectively, the outlet of boosting vaporizer is connected with safety valve behind back-up valve, the outlet of fluid reservoir is connected with the inlet of vaporization pressure regulation unit, also is connected with an implementation of port in the bottom of the fluid reservoir of described liquid storage unit; Be connected with joint vapour pressure-release assembly between the outlet of the outlet of described back-up valve and fluid reservoir, this device is in series by relief valve, Jie Men and pipeline.
This vapourizing unit is divided into three integrated sled pieces: comprise the loading and unloading sled piece of being made up of described unload implementation of port and implementation of port, the liquid storage sled piece of being made up of described liquid storage unit reaches the vaporization pressure regulation sled piece of being made up of described vaporization pressure regulation unit, above-mentioned each sled piece is equipped with pedestal, each relevant apparatus that is connected on pedestal, each prizes interblock has pipe interface to connect.
After taking above technical scheme, its joint vapour pressure-release assembly can not opened this loop when air pressure reaches emptying release of pressure value, makes the LNG of gaseous state be discharged into vaporization pressure regulation unit, does not need the emptying release of pressure, has saved raw material.The implementation of port of setting up at fluid reservoir can be used to the Dewar bottle topping up, to satisfy the demand of transhipment.Integrated sled block structure greatly facilitates the construction that vaporization is stood, and has reduced floor space, has reduced investment.
Description of drawings
Fig. 1 is a composition structural representation of the present utility model;
Fig. 2 is the integrated contour structures schematic diagram of the utility model.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises liquid storage unit A, vaporization pressure regulation unit B and the loading and unloading unit C that is made up of unload implementation of port 1 and implementation of port 2, liquid storage unit A comprises fluid reservoir 3, boosting vaporizer 4, back-up valve 5 and safety valve 6, the implementation of port of unloading 1 is connected with the inlet of fluid reservoir 3 and the inlet of boosting vaporizer 4 with 12 by pipeline 11 respectively, the outlet of boosting vaporizer 4 is connected with safety valve 6 behind back-up valve 5, the outlet of fluid reservoir 3 is connected with the inlet of vaporization pressure regulation unit B, and implementation of port 2 is connected with the bottom of fluid reservoir 3.Be connected with joint vapour pressure-release assembly 7 between the outlet of the outlet of described boosting vaporizer 4 and fluid reservoir 3, this device 7 is in series by relief valve 71, joint 72 and pipeline 73.
This vapourizing unit is divided into three integrated sled pieces, promptly forms loading and unloading sled piece by loading and unloading unit C; Form liquid storage sled piece by liquid storage unit A; Form vaporization pressure regulation sled piece by vaporization pressure regulation unit.Each sled piece is equipped with pedestal D, and at each each relevant apparatus that is connected above the pedestal D, each prizes interblock has pipe interface to connect.
The course of work of the present utility model is as follows: LNG is from unloading implementation of port 1 and by pipeline 11 or 12 fluid reservoir 3 of packing into.Pipeline 11 can make the LNG fluid reservoir 3 of directly packing into, and one road warp of pipeline 12 is from boosting vaporizer 4 vaporizations, change gaseous state into, the top that flows into fluid reservoir 3 by back-up valve 5 reaches the purpose that increases tank interior pressure, LNG flows to vaporization pressure regulation unit B from the pipeline 8 of outlet in the fluid reservoir to force, back-up valve 5 flows to along LNG three bypass lines, one the tunnel leads to safety valve and explosion-protection equipment 6, when the tank body internal pressure be higher than safety valve setting and the time, safety valve is opened and is carried out gas and diffuse, after reducing pressure of storage tank and recovering normally, close automatically.Flow through relief valve 71 of another road increases at pressure of storage tank, but does not reach under the situation of safety valve 6 release pressures, and relief valve 71 is opened, and gaseous natural gas enters fluid pipeline 8 by pipeline 73, plays the effect of inner step-down, need not discharge natural gas to the outside.After pressure of storage tank recovered normally, relief valve 71 cut out automatically.Implementation of port 2 of the present utility model be designed to Dewar bottle supporting fill mouth, be used for into the Dewar bottle inflation, as the caisson of small-scale supply station.
