In one embodiment, the present invention provides a methanol fuel accumulator comprising an accumulator body 1 and a housing 2. Wherein, have pressure storage chamber 11 in the accumulator body 1, and offer the accumulator import 12 and the accumulator export 13 with pressure storage chamber 11 intercommunication on the accumulator body 1. The shape of the accumulator body 1 may be set as desired, and is not particularly limited herein. The wall surface of the accumulator body 1 surrounds and forms a pressure accumulation chamber 11 to store methanol fuel. The accumulator inlet 12 and the accumulator outlet 13 are used for methanol fuel to enter the pressure accumulation cavity 11 and to be discharged from the pressure accumulation cavity 11, and may be specifically disposed at two opposite ends of the accumulator body 1, respectively.
The housing 2 is hermetically connected outside the accumulator body 1, and a housing inlet 21 and a housing outlet 22 are arranged on the housing 2 corresponding to the accumulator inlet 12 and the accumulator outlet 13. The housing inlet 21 corresponds to the housing outlet 22, i.e. methanol fuel enters the pressure accumulation chamber 11 via the housing inlet 21 and the accumulator inlet 12 and can be discharged via the accumulator outlet 13 and the housing outlet 22. An interlayer protection channel 3 is formed between the shell 2 and the pressure accumulator body 1, and an overflow port 14 communicated with the interlayer protection channel 3 is arranged on the shell 2.
Through the setting of shell 2, this methanol fuel accumulator forms double-walled sandwich structure, and the inner wall is the pressure accumulation chamber 11 that the wall of accumulator body 1 encloses promptly, and the outer wall is the outer shell 2 then and the intermediate layer protection channel 3 that forms between accumulator body 1 is the methanol leakage protection channel.
By applying the methanol fuel pressure accumulator provided by the invention, methanol fuel enters the pressure accumulation cavity 11 through the shell inlet 21 and the pressure accumulator inlet 12, is discharged from the pressure accumulator outlet 13 and the shell outlet 22, and is injected to an engine air inlet channel through the alcohol injector. Because the outer shell 2 is arranged outside the pressure accumulator body 1, and the interlayer protection channel 3 is formed between the outer shell 2 and the pressure accumulator body 1, even if the pressure accumulator body 1 leaks, the leaked methanol fuel can enter the interlayer protection channel 3 and can be discharged from the overflow port 14. Therefore, the risk of fire caused by the leakage of the methanol fuel meeting a high-temperature surface is avoided, and the safety of the methanol fuel pressure accumulator is improved.
In one embodiment, the housing 2 is provided with a purge inlet 15 at one end and a purge outlet 16 at the other end, and the purge outlet 16 is open to the outside environment to prevent the accumulation of methanol vapor in enclosed spaces such as the cabin. It should be noted that the open environment here refers to an open space, and if the methanol fuel accumulator is applied to a marine engine system, the open environment may be above a ship deck. By arranging the purge inlet 15 and the purge outlet 16, inert gas can be periodically blown into the sandwich protective channel 3, the inert gas enters from the purge inlet 15, and the gas possibly containing methanol vapor in the sandwich protective channel 3 is purged to the purge outlet 16 and finally discharged to the external environment, so that the risk of methanol vapor accumulation in an engine compartment is avoided. The methanol vapor purged to the external environment will be degraded into carbon dioxide and water in a short time, with much higher environmental safety than existing petrochemical fuels. The purging inlet 15 and the purging outlet 16 are respectively arranged at two opposite ends of the shell 2, so that the purging of the whole interlayer protection channel 3 is facilitated, and the purging effect is good.
Furthermore, the overflow port 14 and the purge outlet 16 share the same opening and are hermetically connected to the header pipe 4, and the purge outlet pipe 5 and the overflow pipe 6 are respectively connected to the header pipe 4. Openings are provided in the housing 2 and serve as overflow 14 and purge outlet 16. The purge inlet 15 and the purge outlet 16 are shared, so that the structure is simplified, and the processing is convenient. The opening is hermetically connected with a main pipe 4, the main pipe 4 is respectively connected with a purging air outlet pipe 5 and an overflow pipe 6, and then the methanol fuel in the interlayer protection channel 3 is discharged into the main pipe 4 through the opening and is discharged through the overflow pipe 6. The methanol vapor in the interlayer protection channel 3 is discharged into the header pipe 4 through the opening under the purging effect of the inert gas and is discharged through the purging air outlet pipe 5. In other embodiments, the overflow port 14 and the purge outlet 16 may be provided separately.
In order to evacuate the methanol fuel as much as possible from the sandwich protective channel 3, in one embodiment an overflow 14 is provided at the lowermost end of the housing 2. In other embodiments, the overflow port 14 may also be disposed in the middle of the side wall of the housing, so that the methanol fuel in the sandwiched protection channel 3 is discharged from the overflow port 14 under the action of its own weight after reaching the height of the overflow port 14.
In one embodiment, the purge outlet pipe 5 extends upwards from the main pipe 4 to an open space above the deck, the top end of the purge outlet pipe 5 is open, the overflow pipe 6 extends downwards from the main pipe 4, and the bottom end of the overflow pipe 6 is open. It should be noted that the upward extension herein includes both vertical upward extension and oblique upward extension, and the downward extension includes both vertical downward extension and oblique downward extension. The methanol fuel can be better discharged from the overflow pipe 6 under the action of gravity, and the methanol steam is discharged through the blowing air outlet pipe 5 under the blowing action.

In other embodiments, the purging air outlet pipe 5 and the overflow pipe 6 may also form an included angle.
In one embodiment, the overflow port 14 is connected to a methanol leak alarm. For the structure and the working principle of the methanol leakage alarm, reference is made to the prior art, and the details are not repeated herein. If fuel of the methanol accumulator leaks, the fuel enters the interlayer protection channel 3, and methanol enters the methanol leakage alarm through the overflow port 14, so that the alarm of the engine safety protection system can be triggered to remind an engine operator to take measures, and the supply of the methanol delivery system can be cut off by the engine safety protection system. In conclusion, the methanol leakage alarm can be used for timely finding the methanol leakage, so that related personnel can be reminded to adopt corresponding operation, or related safety measures can be adopted through the control system. Specifically, the height of the methanol leakage alarm can be set to be lower than that of the overflow port 14, so that methanol enters the methanol leakage alarm from the overflow port 14 under the action of gravity.
Further, a methanol overflow cabin is arranged and connected with the methanol leakage alarm. The methanol entering the methanol leakage alarm can finally enter the methanol overflow compartment, and if the height of the methanol overflow compartment is set to be lower than that of the methanol leakage alarm, the methanol in the methanol leakage alarm can flow to the methanol overflow compartment under the action of the gravity of the methanol leakage alarm, so that the accumulation of the methanol in the engine compartment is avoided. The methanol overflow device has the advantages that methanol can overflow under the action of gravity of the methanol due to the arrangement of the heights of all the parts, and the structure is simple.
