Abstract

The utility model discloses a novel efficient LNG (Liquefied Natural Gas) gasifier which comprises a gasification chamber and an LNG gasification pipe, wherein the pipe body of the LNG gasification pipe is arranged in the gasification chamber; the inlet and outlet of the LNG gasification pipe are formed at the exterior of the gasification chamber; the LNG gasifier further comprises an air fan and a combustor; a first air inlet of the combustor is communicated with the outlet of the air fan; a fuel gas pipe is arranged at a second gas inlet of the combustor; an adjustable valve is arranged on the fuel gas pipe; a combustion bin is arranged in the gasification chamber; the flame opening of the combustor is opposite to the flame inlet of the combustion bin. According to the novel efficient LNG gasifier, the combustor is used for spraying out high-temperature flame into the gasification chamber, so as to heat a medium added in the gasification chamber, the high-temperature flame is directly contacted with the medium and the medium is fiercely stirred by the air flow generated by the high-temperature flame, and thus the heat transmission efficiency is quite high and the gasification efficiency can be remarkably improved, especially when the environment temperature is relatively low; the adjustable valve can be used for adjusting the fuel feed amount in real time, so that the waste is reduced and the use cost is lowered.

Description

A kind of new and effective LNG vaporizer

Technical field

The utility model relates to a kind of LNG vaporizer, relates in particular to a kind of new and effective LNG vaporizer.

Background technique

Along with social development and scientific and technological development, the natural gas supply system of China is more and more perfect, LNG(liquefied natural gas, LNG Liquefied natural gas) vaporizer is the necessaries for the state conversion of LNG Liquefied natural gas, be mainly used to convert LNG Liquefied natural gas to gas, thereby be transported in natural gas supply network.Traditional LNG vaporizer is owing to carrying out at ambient temperature all the time, so its gasification efficiency is lower in the time that temperature is lower, user cost is higher.

Summary of the invention

The purpose of this utility model is just to provide in order to address the above problem a kind of new and effective LNG vaporizer.

The utility model is achieved through the following technical solutions above-mentioned purpose:

A kind of new and effective LNG vaporizer, comprise gasification room and LNG gasifying pipe, the body of described LNG gasifying pipe is placed in described gasification room inside, the import of described LNG gasifying pipe and outlet are all placed in described gasification room outside, described LNG vaporizer also comprises air blower and burner, the first suction port of described burner is communicated with the outlet of described air blower, the second suction port of described burner is provided with fuel gas pipe, on described fuel gas pipe, be provided with adjustable valve, in described gasification room, be provided with combustion bin, the flame hole of described burner is the flame entrance to described combustion bin just.

By air blower, burner, fuel gas pipe and combustion bin are set, ensure in gasification room, to send into the condition of hot flame, thereby by the medium that adds gasification room inside to, LNG gasifying pipe has been carried out to dynamic heat, gasification efficiency is very high; Adjustable valve is set on fuel gas pipe, can, according to the actual conditions fuel metering amount of sending into, have reduced cost.

For the waste gas that makes burning can be discharged gasification room in time, the top of described gasification room is provided with gas of combustion outlet.

Particularly, described combustion bin is L-type siphunculus, can ensure to a certain extent that like this heating space in gasification room is enough large.

The beneficial effects of the utility model are:

The utility model can be by burner to the inner ejection of gasification room hot flame, with this, medium that adds gasification room inside to is heated, hot flame directly contacts with medium, the fierce medium that stirs of air-flow that hot flame produces, make its heat transfer efficiency very high, in the time that ambient temperature is lower, can significantly improve gasification efficiency especially; Can, according to the actual conditions fuel metering amount of sending into, therefore reduce waste by adjustable valve, reduce user cost.

Brief description of the drawings

Fig. 1 is the structural representation of new and effective LNG vaporizer described in the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1, the utility model comprises gasification room 3, LNG gasifying pipe 7, air blower 4 and burner 5, the body of LNG gasifying pipe 7 is placed in gasification room 3 inside, the import A of LNG gasifying pipe 7 and outlet B are all placed in gasification room 3 outsides, the first suction port of burner 5 is communicated with the outlet of air blower 4, the second suction port of burner 5 is provided with fuel gas pipe 2, on fuel gas pipe 2, be provided with adjustable valve 1, in gasification room 3, be provided with combustion bin 8, combustion bin 8 is L-type siphunculus, the flame hole of burner 5 is the flame entrance to combustion bin 8 just, wherein the top of gasification room 3 is also provided with gas of combustion outlet 6.

The working principle of a kind of new and effective LNG vaporizer described in the utility model is as follows:

Here the medium adding to gasification room 3 inside is water, in LNG gasifying pipe 7, add liquified natural gas by import A, fuel inlet C by fuel gas pipe 2 sends constantly into gaseous fuel and enters in burner 5 in fuel gas pipe 2, can be according to the actual conditions fuel metering amount of sending into by adjustable valve 1, so just reduce waste, reduce cost, constantly in burner 5, send into the air for auxiliary gas fuel combustion by air blower 4, directly in water, spray hot flame by burner 5, because hot flame directly contacts with water, the fierce agitate water of air-flow that hot flame produces, make its heat transfer efficiency very high, water upwards flows along the pipeline of LNG gasifying pipe 7, liquified natural gas constantly absorbs heat gasification, by outlet, B sends the rock gas after gasification, total thermal efficiency of whole gasification installation is in 98% left and right.Export 6 by gas of combustion and can make the waste gas of burning can discharge in time gasification room 3, combustion bin is selected L-type siphunculus, can ensure to a certain extent that like this heating space in gasification room is enough large.
