Description

Technical Field

[0001] This application relates to the field of energy supply technology, and in particular to a skid-mounted vehicle for methanol gas supply. Background Technology

[0002] Methanol is the simplest saturated monohydric alcohol. With its diverse sources, active chemical properties, and wide range of applications, it is an irreplaceable clean energy carrier and is also often used as a substitute for fossil fuels.

[0003] In existing technologies, skid-mounted systems mostly rely on solar collectors to power methanol vaporization. Formic acid produced during methanol production (even at a content of 0.1%) can cause electrochemical corrosion to ordinary stainless steel (such as 304) pipes, valve welds, and seals, leading to fuel leaks and unstable energy supply. Existing skid-mounted systems only calculate the "optimal methanol-air mixture ratio" based on national standards, failing to consider the dynamic fluctuations in pressure and flow during system operation, which can easily lead to problems such as "excess air → reduced combustion temperature" or "excess methanol → accumulation of unburned vapors, increasing the risk of combustion and explosion," thus failing to guarantee long-term stable combustion.

[0004] Therefore, there is an urgent need for a skid-mounted vehicle for methanol fuel supply to solve the above problems. Utility Model Content

[0018] Combination Figures 1-4As shown, a skid-mounted vehicle for methanol fuel supply includes a storage tank 2, a deacidification assembly 20, an air compressor 30, an air preheater 40, a mixing assembly 50, a gas storage tank 1, a heating assembly 60, a heater 70, and a recovery tank 3. The output end of the storage tank 2 is connected to the input end of the deacidification assembly 20; the output end of the deacidification assembly 20 is connected to the first input end of the mixing assembly 50; the input end of the air compressor 30 is connected to the external air environment, and its output end is connected to the first input end of the air preheater 40; the output end of the air preheater 40 is connected to the mixing assembly 50. The second input terminal of the mixing component 50 is connected to the input terminal of the gas storage tank 1; the first output terminal of the gas storage tank 1 is connected to the input terminal of the heater 70; the first output terminal of the heater 70 is connected to the input terminal of the external demand environment, and the second output terminal of the heater 70 is connected to the input terminal of the recovery tank 3, which is used to store residual gas; the first output terminal of the heating component 60 is connected to the second input terminal of the deacidification component 20, and the second output terminal of the heating component 60 is connected to the second input terminal of the air preheater 40.

[0019] In the above scheme, the direct connection between the storage tank 2 and the deacidification component 20 allows the methanol liquid to be neutralized by acidic substances before entering the mixing process, avoiding electrochemical corrosion of the pipeline by formic acid; the series connection of the air compressor 30 and the air preheater 40 compresses the external air and preheats it to a suitable temperature, ensuring that the air has sufficient thermodynamic activity before mixing; the mixing component 50 integrates the deacidified methanol and preheated air through dual inputs to form a stable gaseous mixed fuel, ensuring long-term stable combustion of the fuel; the gas storage tank 1 serves as a buffer unit to store the mixed fuel gas, which, together with the heater 70, is supplied on demand, while the recovery tank 3 collects the unused residual fuel gas, avoiding energy waste and the risk of explosion; the heating component 60 simultaneously supplies heat energy to the deacidification component 20 and the air preheater 40, maintaining the temperature required for the deacidification reaction and improving the air preheating efficiency, forming an energy recycling system.

[0020] The deacidification component 20 includes a liquid preheater 21, a neutralization tower 22, an alkali transfer pump 23, and a gas-to-gas heat exchanger 24. The input end of the liquid preheater 21 is connected to the output end of the storage tank 2, and the output end of the liquid preheater 21 is connected to the first input end of the neutralization tower 22. The input end of the alkali transfer pump 23 is connected to the output end of the external alkali supply, and its output end is connected to the second input end of the neutralization tower 22. The first input end of the gas-to-gas heat exchanger 24 is connected to the output end of the neutralization tower 22, and the output end of the gas-to-gas heat exchanger 24 is connected to the first input end of the mixing component 50.

[0021] In the above scheme, the liquid preheater 21 preheats the methanol from the storage tank 2 to reduce the liquid viscosity and improve the efficiency of the subsequent neutralization reaction; the neutralization tower 22 introduces external alkali supply through the alkali transfer pump 23 to ensure that the preheated methanol and alkaline substances are in full contact to achieve the neutralization reaction of formic acid and eliminate the risk of corrosion of metal pipelines by acidic substances; the gas-to-gas heat exchanger 24 exchanges heat with the neutralized gas, which not only recovers the waste heat of the reaction to improve the system energy efficiency, but also ensures that the gas reaches a suitable state before entering the mixing component 50 through temperature regulation.

[0022] The mixing assembly 50 includes a mixing tank 51, a turbulence-inducing component 52, and an annular plate 53. The first input end of the mixing tank 51 is connected to the output end of the gas-to-gas heat exchanger 24, the second input end of the mixing tank 51 is connected to the output end of the air preheater 40, and the output end of the mixing tank 51 is connected to the input end of the gas storage tank 1. The turbulence-inducing component 52 is disposed at the connection between the mixing tank 51 and the gas-to-gas heat exchanger 24 and at the connection between the mixing tank 51 and the air preheater 40. The annular plate 53 is disposed at the connection between the mixing tank 51 and the gas storage tank 1, and the axis of the annular plate 53 is coaxially arranged with the axis of the connection between the mixing tank 51 and the gas storage tank 1. The surface of the annular plate 53 is provided with a plurality of vortex grooves 531 recessed towards its axis. The plurality of vortex grooves 531 are equally spaced along the axis of the annular plate 53 and form a vortex structure.

[0023] In the above scheme, the turbulence-disrupting element 52 is installed at the connection between the mixing tank 51 and the gas-to-gas heat exchanger 24 and air preheater 40. By actively disturbing the airflow, it breaks the laminar flow state, allowing methanol and air to undergo preliminary turbulent mixing upon entering the mixing tank 51, thus solving the gas stratification problem caused by dynamic pressure fluctuations. The annular plate 53 is equipped with a structure with vortex grooves 531 at the outlet of the mixing tank 51. The equally spaced grooves guide the mixed gas to form a rotating vortex, enhancing the secondary mixing effect of the airflow and ensuring that the mixed gas reaches a uniform state before entering the gas storage tank 1. The specific structure of the vortex grooves 531, which are recessed towards the axis, enhances the centrifugal effect, allowing gas components of different densities to fully mix and avoiding local over-mixing caused by uneven mixing.

[0024] The agitator 52 includes a connecting pipe 521, multiple connecting rods 522, a connecting plate 523, a connecting bearing 524, and a fan blade 525. The input end of the connecting pipe 521 is connected to the connection between the mixing tank 51 and the gas-to-gas heat exchanger 24, and the connection between the mixing tank 51 and the air preheater 40, respectively, and its output end extends into the interior of the mixing tank 51. One end of the multiple connecting rods 522 is arranged in a ring around the outer periphery of the output end of the connecting pipe 521, and the other end extends into the interior of the mixing tank 51. The connecting plate 523 is horizontally fixed to one end of the multiple connecting rods 522 away from the connecting pipe 521. One end of the connecting bearing 524 is fixedly connected to the side of the connecting plate 523 near the connecting rods 522, and its axis is coaxial with the axis of the connecting pipe 521. The fan blade 525 is fixedly disposed on the inner ring of the connecting bearing 524 and forms a rotational fit.

[0025] In the above scheme, the connecting pipe 521 extends into the mixing tank 51, creating a directional flow path between the incoming methanol fuel gas and the preheated air. The supporting frame formed by the ring arrangement of connecting rods 522 ensures structural stability while avoiding obstruction of the main fluid. The connecting plate 523 and the connecting bearing 524 are axially coaxial, ensuring that the rotation axis of the fan blade 525 is consistent with the airflow direction, and the fan blade 525 is driven to rotate by fluid kinetic energy. The fan blade 525 rotates dynamically with the airflow under the support of the bearing, forming a spiral vortex disturbance, breaking the laminar flow state and enhancing the gas-liquid two-phase contact, thereby ensuring sufficient mixing of methanol and air for long-term stable combustion of the non-combustible fuel.

[0026] The heating assembly 60 includes a solar collector 61 and a heat exchanger 62; the output end of the solar collector 61 is connected to the input end of the heat exchanger 62, the first output end of the heat exchanger 62 is connected to the second input end of the air preheater 40, and the second output end of the heat exchanger 62 is connected to the second input end of the gas-to-gas heat exchanger 24.

[0027] In the above scheme, the solar collector panel 61 provides renewable energy, reducing dependence on external energy sources. The heat exchanger 62, with its split configuration, transfers heat to the air preheater 40 (for preheating air) and the gas-to-gas heat exchanger 24 (for regulating the temperature of the methanol fuel gas after deacidification), thereby maintaining the temperature requirements of the deacidification component 20 and the mixing component 50 during initial system startup or when the mixed gas reserve is insufficient, preventing gasification interruption. The dual-output design of the heat exchanger 62 enables precise distribution of heat energy, ensuring stable temperature control of the mixed gas by the air preheater 40 and improving deacidification efficiency through the gas-to-gas heat exchanger 24.

[0028] This application also includes a compensation component 80; the input end of the compensation component 80 is connected to the second output end of the air storage tank 1, and the output end of the compensation component 80 is connected to the second input end of the air preheater 40; wherein, the compensation component 80 includes a solenoid valve 81, a compensation pipeline 82, and an air pump 83; the solenoid valve 81 is installed at the second output end of the air storage tank 1; the input end of the compensation pipeline 82 is connected to the output end of the solenoid valve 81, and its output end is connected to the input end of the air pump 83; the output end of the air pump 83 is connected to the second input end of the air preheater 40.

[0029] In the above scheme, the input end of the compensation component 80 is connected to the second output end of the gas storage tank 1, forming a closed-loop feedback path. When insufficient pressure is detected in the gas storage tank 1, the residual gas is released by opening the solenoid valve 81. The gas is then transported to the air pump 83 for pressurization via the compensation pipeline 82 and re-injected into the air preheater 40. The solenoid valve 81 enables intelligent opening and closing control of the output end of the gas storage tank 1, avoiding gas waste. The compensation pipeline 82 establishes a gas return channel, and the air pump 83 performs secondary pressurization on the return gas, ensuring that the gas can overcome system resistance and re-enter the preheating cycle. This maintains a stable gas supply pressure in the air preheater 40 and ensures the system's continuous operation capability under low-load conditions.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
