Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction, in particular to an automatic temperature control device for a chemical reaction kettle. Background Art

[0002] Chemical reactor is a kind of equipment widely used in chemical production, mainly used to complete chemical reactions between liquids. Reactors are usually made of stainless steel, carbon steel or other corrosion-resistant materials, with good sealing performance and high temperature and pressure resistance. Reactors used for chemical synthesis reactions need to control the temperature of the liquid in the reactor during certain reactions.

[0003] During use, the existing reactor temperature control device has low working efficiency in regulating the temperature of the liquid in the reactor, and cannot automatically and quickly regulate the temperature of the liquid in the reactor. When regulating the temperature, the amount of liquid in the reactor is prone to increase or decrease, which affects the effect of chemical synthesis reaction. Based on these problems, Chinese patent CN214514472U discloses an automatic temperature control device for a reactor based on chemical synthesis reaction. The device flows the liquid in the reactor into a temperature regulating tank through a circulation pipe, and uses a circulation pump to pump the liquid in the temperature regulating tank into the reactor through a liquid guide pipe, so that the liquid is in a circulating flow state. The temperature of the liquid in the temperature regulating tank can be monitored in real time by a temperature sensor. When the temperature is lower than a preset value, a liquid pump b pumps the hot liquid tank into the reactor. The hot liquid in the reactor is pumped into the temperature regulating tank through the hot liquid pipe, and the liquid pump pumps the liquid in the reactor body into the cold liquid tank through the cold liquid pipe until the liquid temperature is raised to the preset temperature. When the temperature is higher than the preset value, the liquid pump c pumps the cold liquid in the cold liquid tank into the temperature regulating tank through the cold liquid pipe, and the liquid pump a pumps the liquid in the reactor body into the hot liquid tank through the hot liquid pipe until the liquid temperature drops to the preset temperature. The temperature of the liquid in the reactor body can be automatically and quickly regulated, which is convenient for continuous and accurate monitoring and regulation of the temperature of the liquid in the reactor body. At the same time, the temperature regulation can keep the amount of liquid in the reactor body in a constant state, which is beneficial to improving the working efficiency of the temperature regulation of the liquid in the reactor body and preventing the increase or decrease of the amount of liquid in the reactor body from affecting the reaction effect.

[0004] When the liquid pump draws the liquid in the reactor body through the cold liquid conduit or the hot liquid conduit to the cold liquid tank and the hot liquid tank respectively, since the liquid in the reactor body itself has a certain temperature, if the temperature of this liquid is higher than the temperature of the liquid in the cold liquid tank and lower than the temperature of the liquid in the hot liquid tank, the liquid will be transported to the cold liquid tank and the hot liquid tank respectively, which will not only increase the overall temperature of the liquid in the cold liquid tank, but also reduce the overall temperature of the liquid in the hot liquid tank, thereby affecting the temperature control effect of the liquid in the temperature control tank and making it difficult to control the amount of liquid in the reactor.
