Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical additive production, and more specifically to a safety protection device in the production of oilfield chemical additives. Background Art

[0002] In the production process of petrochemical additives, the synthesis reaction often requires the addition of initiators. The amount of initiator added and the speed of addition play a vital role in the smooth progress of the reaction. In order to prevent the risk of explosion during the production of chemical additives, safety protection devices are usually installed. However, in actual use, it may not be possible to quickly and stably control the initiation temperature, and it is also impossible to quickly and evenly add the initiator and inhibitor to the chemical additive, which reduces the safety protection performance.

[0003] For example, announcement No. CN220026940U discloses an initiating device for the production of petrochemical additives, which includes a stirring tank and a stirring device. The stirring device includes a stirring motor fixedly connected to the outer wall of the stirring tank, and the output end of the stirring motor is fixedly connected to a stirring roller. A fence-shaped stirring assembly is provided at one end of the stirring roller. The fence-shaped stirring assembly is located inside the stirring tank, and a connecting pipe is symmetrically inserted on one side of the stirring tank.

[0004] It can be seen from the above-mentioned disclosed scheme that when adding initiators and inhibitors, they can only be added to the upper surface of the chemical additive raw material, and then evenly added by stirring and mixing. This process takes a long time, which increases the probability of implosion. In addition, when controlling the temperature of the internal chemical additive, the cold medium in the intermediate flow cavity needs to cool the inner wall of the stirring tank before it can be transferred to the chemical additive raw material. This process takes a long time, which reduces the control stability of the initiation temperature. Utility Model Content
