Methanol-based fuel high-pressure supplying device

Abstract

The invention discloses a methanol-based fuel high-pressure supplying device. The device comprises a methanol tank, a water tank and a dimethyl ether tank which respectively contain methanol, water and dimethyl ether; both the methanol tank and the water tank are connected with pre-pressurizing systems; the dimethyl ether tank is connected with a mixed measuring system; the pre-pressurizing systems and the mixed measuring system are connected, wherein the mixed measuring system is sequentially connected with a pressurizing system and an engine; in addition, the pressurizing system and the pre-pressurizing systems are all connected with air compressing devices. The methanol-based fuel high-pressure supplying device has the beneficial effects that methanol, dimethyl ether and water are mixed based on different ratios; in addition, the online control is realized; the demand on material supply at different pressures can be realized under a high pressure of 100 MPa; meanwhile, the flow rate can be adjusted within a certain range, and the utilization rate of the methanol-based fuel can be raised; the supplying system has a wide range of output pressure and can directly enter an internal combustion engine and other energy consumption devices without pressure reduction, and thus the energy consumption can be reduced; the self-cooling is realized, the operation can be individually performed, the pollution resource is avoided, and the long-time, safe, stable and reliable operation is reached.

Description

[0001] technical field [0002] The invention relates to a methanol-based fuel high-pressure feeding device. [0003] Background technique [0004] With the rapid development of the economy, the degree of environmental pollution is increasing, making people pay more and more attention to the protection of the environment. In response to the increasingly severe dual pressure of energy supply and environmental protection, new clean energy, methanol-based fuel is being actively studied at home and abroad. As a clean alternative fuel for internal combustion engines (diesel engines), it has shown its great potential for development; at present, the combustion performance and emissions of methanol-based fuels are being actively studied at home and abroad, and significant results have been achieved; however, the supporting feeding equipment for the research is still in the traditional stage.

AI Technical Summary

Problems solved by technology

[0006] 1) Single function, complex operation, large volume and weight, and low degree of automation;

[0007] 2) Electronic scales are used when mixing the components of methanol-based fuel, the ratio is not accurate and cannot be adjusted online;

[0008] 3) It is directly driven by the motor, the circulation speed cannot be adjusted, the flow rate cannot be changed, and it cannot be flexibly used for various pressure feeding;

[0009] 4) The inlet pressure range is narrow. When the inlet pressure is high, a pressure reducing device is generally required to reduce pressure, or an overflow valve is used, which wastes energy. It is a blind addition, and the safety factor is not high;

[0010] 5) It needs to be equipped with additional power and cooling equipment, which is costly and easy to cause pollution;

[0011] 6) Currently there is no 100MPa high pressure feeding system

[0012] The main reasons for the above problems are the limitations of electric pump technology and relatively little domestic investment and research in this field, and the lack of attention to multi-functional, automated systems, and environmentally friendly products
