Description
Technical field
The utility model relates to LNG vaporization equipment technical field more particularly to a kind of direct-fired LNG gasification devices.
Background technique
LNG (Liquef ied Natura l Gas, i.e. liquefied natural gas), LNG is in use, need to convert liquid to
Gaseous state is carried out using liquified natural gas is gasified by needing to be arranged heating mechanism.What current LNG gasification device generally used
It is air temperature gasification mode；Or gasified using electric heating, then exchanged heat by water and LNG to achieve the purpose that gasification；Or
Direct hot water and LNG exchange heat to achieve the purpose that gasification.Major defect present in it is：Gasification efficiency is low, and air outlet temperature is not
Controllably, it takes up a large area, investment is big, and maintenance cost is high.
Utility model content
Purpose of the utility model is to overcome the shortcomings of the above technology, and to provide a kind of direct-fired LNG gasification devices.
The utility model to achieve the above object, using following technical scheme：A kind of direct-fired LNG gasification device, it is special
Sign is：Including shell, gasification coil pipe, gasification coil pipe material inlet, gasification coil pipe material outlet, combustion chamber；The combustion chamber
It is independently arranged at the inner hub location of the shell, the gasification coil pipe is coiled in around the combustion chamber, and gasify coil pipe
Material inlet, gasification coil pipe material outlet are connected and fixed to the outside of the shell with the both ends of the gasification coil pipe respectively,
The side of the combustion chamber is equipped with burner connecting flange.
Preferably, the outside of the shell is equipped with protective case.
Preferably, temperature transmitter, thermometer and liquidometer are respectively equipped on the shell.
Preferably, the side of the combustion chamber is equipped with glory hole.
The utility model has the beneficial effects that:Compared with the existing technology, hollow portion of the utility model in shell and coil pipe
Dividing has a combustion chamber, and the top of combustion chamber, which is stretched out outside shell, facilitates smoke evacuation, and the method for neat gas burner is arranged at the lower part of combustion chamber
Blue interface heats the water of enclosure interior for connecting burner, and LNG enters gasification from the material inlet of gasification coil pipe
Coil pipe, the LNG in coil pipe absorbs heat from by coil pipe wall from hot water, to achieve the purpose that gasification.Using directly heating
Mode gasification efficiency not only can be improved, but also occupied area can be reduced；For ease of maintenaince, maintenance cost and maintenance difficulty are reduced.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Specific embodiment
With reference to the accompanying drawing and specific embodiment of the present utility model is described in detail in preferred embodiment.As shown in Figure 1, one
Kind direct-fired LNG gasification device, including shell 2, gasification coil pipe 3, gasification coil pipe material inlet 4, gasification coil pipe material outlet 5,
Combustion chamber 6；In order to keep the temperature to shell, the outside of the shell is equipped with protective case 1.
The combustion chamber is independently arranged at the inner hub location of the shell, seals when between shell, in shell
Portion needs to be passed through water as medium, and the gasification coil pipe is coiled in around the combustion chamber, can transit chamber after combustion chamber heating
Wall heats the intracorporal water of shell, gasification coil pipe material inlet, gasification coil pipe material outlet respectively with the gasification coil pipe
Both ends are connected and fixed to the outside of the shell, by gasification coil pipe material inlet, gasification coil pipe material outlet to gasification disk
LNG is passed through in pipe.For the ease of connecting with burner, the side of the combustion chamber is equipped with burner connecting flange 7.For the ease of
The side of the case where observing combustion chamber flame, the combustion chamber is equipped with glory hole 8.Temperature is respectively equipped on the shell
Transmitter 9, thermometer 10 and liquidometer 11, for being observed situations such as water temperature, water level in shell.
Working principle：
It after the burner ignition of combustion chamber external connection, burns in combustion chamber, flue gas passes through the chimney on the upside of combustion chamber
It exhausting, flue gas is heated (water is medium) to the intracorporal water of shell by the outer wall of combustion chamber, after heating the water to certain temperature,
LNG enters gasification coil pipe from the material inlet of gasification coil pipe, and the LNG in coil pipe absorbs heat from by coil pipe wall from hot water,
To achieve the purpose that gasification.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
