背景技术Background technique
常温下呈气态的物质与空气进行预混，在技术上对其进行控制的难度较低，较为容易实现，但对于常温下为液态的物质，将其与空气进行预混时，涉及到对该液态物质的汽化，技术实现难度较大，且部分液态物质具有毒性，存在较大的安全隐患。例如己烷与空气的预混，一般需先将己烷进行汽化，其后与空气以一定的比例进行混合，目前，缺少一种能够保证实现己烷汽化及其与空气进行预混的装置。Premixing a gaseous substance with air at room temperature is technically less difficult and easier to achieve, but for a liquid substance at room temperature, when premixing it with air, it involves the The vaporization of liquid substances is difficult to achieve technically, and some liquid substances are toxic, which poses a greater safety hazard. For example, the premixing of hexane and air generally requires vaporizing hexane first, and then mixing with air in a certain proportion. At present, there is a lack of a device that can ensure vaporization of hexane and premixing with air.
因此，希望有一种技术方案来克服或至少减轻现有技术的至少一个上述缺陷。Therefore, a technical solution is desired to overcome or at least alleviate at least one of the above-mentioned deficiencies of the prior art.
