Reaction kettle for preparing biodiesel from crop straws

The invention discloses a reaction kettle for preparing biodiesel from crop straws, and relates to the technical field of mechanical design and manufacturing, a pressurized atomization mechanism is arranged at the top of a reaction kettle main body, a separation mechanism is arranged at the inner bottom of the reaction kettle main body, and the reaction kettle main body is arranged on a base. The contact area of the reaction raw materials and the catalyst can be increased, so that the reaction rate is increased, the separation process of the reaction product can be simplified, the tedious process of separating the catalyst from the product after the reaction is avoided, and the integrated design of separating the raw material mixed product is realized; on the basis of shortage of existing biodiesel preparation reaction containers and low reaction efficiency, the device provides a sufficient and efficient reaction environment for reaction raw materials; in the operation process, the device is simple in structu
