Description

Technical Field

[0001] This utility model relates to the field of fuel mixing technology, specifically a mixing device for methanol and diesel. Background Technology

[0002] In today's energy sector, with increasingly stringent environmental protection requirements and the pursuit of energy diversification, the search for efficient and clean alternative fuels has become a research hotspot. Methanol, as a promising clean fuel, has attracted widespread attention due to its advantages such as wide availability of raw materials, relatively low price, good combustion performance, and low pollutant emissions. Blending methanol with diesel can not only alleviate the pressure of petroleum resource shortages to a certain extent, but also effectively reduce pollutant emissions during combustion, which is of great significance for promoting sustainable energy development.

[0003] Currently, methanol, as a clean fuel, can be mixed with diesel. Many existing mixing devices use dynamic agitators, which are prone to insufficient mixing during use. When stored for a long time, the stratification phenomenon is more obvious, which can easily affect the fuel combustion efficiency. Therefore, we propose a mixing device for methanol and diesel to solve the above problems. Utility Model Content
