Description

TECHNICAL FIELD

[0001] The utility model relates to the field of reaction kettle, especially in a kind of methyl ethyl methane synthesis reaction kettle of improving synthesis efficiency. BACKGROUND

[0002] Methyl ethyl methane synthesis reaction kettle is a kind of equipment specially designed for methyl ethyl methane (also known as propane) synthesis reaction. The reaction kettle is mainly composed of stirrer, tank body, jacket, pressure pipe, manhole, shaft seal, transmission device and support, etc. Among them, the stirrer plays a crucial role in the reaction process, which can ensure that the reaction materials are uniformly mixed in the tank body, improve the reaction efficiency and product quality. The tank body is the main place for reaction, usually made of corrosion-resistant and high-temperature-resistant materials to withstand high pressure and high temperature during the reaction. In the synthesis reaction of methyl ethyl methane, the stirrer in the reaction kettle will drive the stirring blade to rotate, so that the reaction materials are fully mixed. At the same time, the jacket outside the tank body can be connected to cooling or heating medium to control the reaction temperature. Temperature sensor monitors the reaction temperature in real time to ensure that the reaction is carried out in a safe and efficient temperature range. In addition, methyl ethyl methane synthesis reaction kettle also has some special design to improve the reaction efficiency and product purity. For example, some reaction kettles use multi-layer stirring blade design to mix reaction materials more effectively; some reaction kettles have automatic cleaning function to clean the inside of the tank after reaction, reducing impurities.

[0003] In the current industrial production process, the stirring operation of methyl ethyl methane synthesis reaction kettle usually relies on impeller or stirring rod as stirring mechanism to complete. Although this method has been widely used in practice, it is undeniable that these stirring mechanisms have certain limitations in stirring efficiency, which leads to the need for longer time to achieve ideal uniform stirring effect in actual operation.

[0004] In detail, when using stirring rod or impeller for stirring, the fluid flow pattern formed inside the reaction kettle tends to be single, which may adversely affect the mixing effect of materials in the reaction kettle. Especially when dealing with materials with high viscosity and high density characteristics, the stirring efficiency of stirring rod or impeller is often more challenged, because the agitation and mixing of such materials are more difficult, and more time and energy input are needed to achieve full mixing.
