[0002] The existing biodiesel production mainly uses waste oil as raw material, and produces crude fatty acid methyl ester through two-step chemical methods of esterification and transesterification. After the crude methyl ester enters the biodiesel distillation tower, it is heated to 250°C with heat transfer oil. Under negative pressure of -0.05MPa, qualified products are obtained from different distillation towers according to different boiling points. Among them, the use of heat transfer oil to control the temperature of crude methyl ester has a greater impact on product quality, and the control of crude methyl ester temperature requires the stabilization of the heat transfer oil temperature to ensure product quality. In the actual production process of biodiesel, it is inevitable that sometimes unexpected reasons cause short-term power outages or false alarms of combustible gas alarm controllers, causing the natural gas electromagnetic gas emergency shut-off valve to start and automatically close. When the external power is restored to normal, the organic heat carrier furnace needs to be quickly opened to stabilize the temperature of the heat transfer oil. First, the natural gas electromagnetic gas emergency shut-off valve must be manually reset. When the nominal diameter of the electromagnetic gas emergency shut-off valve is greater than 150 mm, the existing manual reset method is time-consuming and laborious, affecting the normal production.
