Description
Technical field
The present invention relates to a kind of gasifier, more specifically to a kind of two-stage type gasifier belongs to automobile engine skill
Art field.
Background technique
Currently, the extensive use with liquefied natural gas on vehicle, component capabilities in feed system increasingly by
To concern, gasifier is exactly one of critical component.Gasifier is to hand over -162 DEG C of ultralow temperature liquified natural gas through overheat
Ventilation formation gas, and it is heated to the device of certain temperature, heat exchange medium is engine coolant.
Since natural gas temperature is too low, causes the heat exchanger in gasifier that can only take co-current mode, prevent coolant liquid
Crystallization even freezes；But the heat exchanger effectiveness of downstream heat transfer is relatively low, gasification rate is slow, is not able to satisfy engine and suddenly accelerates
Operating condition.
Summary of the invention
It is an object of the invention to can only take heat existing for co-current mode for the heat exchanger in existing gasifier
The defects of exchange efficiency is relatively low, gasification rate is slow provides a kind of two-stage type gasifier.
To achieve the above object, the technical solution of the invention is as follows: a kind of two-stage type gasifier, including shell, described
Shell in be provided with natural gas line, the Imported gas and gas outlet at natural gas line both ends are located at shell two
It holds, is provided with partition in shell, gasifier shell is divided into two independent preheating cavities and main heat exchange chamber, and day by the partition
Right gas import is located at preheating cavity end, and Imported gas is located at main heat exchange chamber end, is provided with and preheats on the shell of the preheating cavity
The preheating cavity water inlet and preheating cavity water outlet that chamber is connected are provided on the shell of the main heat exchange chamber and are connected with main heat exchange chamber
Logical main heat exchange chamber water inlet and main heat exchange chamber water outlet.
Compared with prior art, the beneficial effects of the present invention are:
The present invention includes two heat exchange cavitys of preheating cavity and main heat exchange chamber, and preheating cavity is using co-current mode to natural gas liquid
Body is preheated, preliminary to complete gasification；Main heat exchange chamber then uses counter-flow pattern to heat cryogenic natural gas, is rapidly completed
Cryogenic gas heating；Therefore the requirement of gasification rate and temperature rise is able to satisfy when suddenly accelerating.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is perspective view of the present invention.
In figure: shell 1, natural gas line 2, Imported gas 3, gas outlet 4, partition 5, preheating cavity 6, main heat exchange chamber
7, preheating cavity water inlet 8, preheating cavity water outlet 9, main heat exchange chamber water inlet 10, main heat exchange chamber water outlet 11.
Specific embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail.
Referring to Fig. 1 to Fig. 2, a kind of two-stage type gasifier belongs to a kind of liquefied natural gas gasifying device, including shell 1.Institute
Natural gas line 2 is provided in the shell 1 stated, the Imported gas 3 and gas outlet 4 at 2 both ends of natural gas line distinguish position
In 1 both ends of shell.
Referring to Fig. 1 to Fig. 2, partition 5 is provided in shell 1, gasifier shell 1 is divided into two independences by the partition 5
Preheating cavity 6 and main heat exchange chamber 7；And Imported gas 3 is located at 6 end of preheating cavity, Imported gas 4 is located at 7 end of main heat exchange chamber.Institute
State the preheating cavity water inlet 8 and preheating cavity water outlet 9 for being provided on the shell 1 of preheating cavity 6 and being connected with preheating cavity 6, the master
The main heat exchange chamber water inlet 10 and main heat exchange chamber water outlet 11 being connected with main heat exchange chamber 7 are provided on the shell 1 of heat exchanging chamber 7.
Referring to Fig. 1 to Fig. 2, when engine is run, natural gas is entered by Imported gas 3, flows to the another of natural gas line 2
One end, and engine aspirating system is flowed out to through gas outlet 4.Water flow is respectively by the preheating cavity water inlet 8 of preheating cavity 6 and master
The main heat exchange chamber water inlet 10 of heat exchanging chamber 7 enters preheating cavity 6 and main heat exchange chamber 7, after completing heat exchange with natural gas, then respectively from
The preheating cavity water outlet 9 of preheating cavity 6 and the main heat exchange chamber water outlet 11 of main heat exchange chamber 7 flow out.To complete entire heat exchange
Journey.In the process, the water (flow) direction of preheating cavity 6 is consistent with natural gas flow direction, is downstream heat transfer, makes liquified natural gas gas
Guarantee that coolant liquid will not be freezed while change；The water (flow) direction of main heat exchange chamber 7 is contrary with natural gas flow, changes for adverse current
Heat, heat exchange efficiency are higher than co-current mode, accelerate gasification rate and natural gas temperature rise, and realization is divided into two-stage and gasifies to natural gas
And heating, it had not only improved heat exchanger effectiveness but also had effectively prevented the risk that coolant liquid crystallization even freezes.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, and above structure all shall be regarded as belonging to
Protection scope of the present invention.
