[0002] Petrochemical industry generally refers to the chemical industry that uses petroleum and natural gas as raw materials. It has a wide range and many products. Crude oil is cracked, reformed and separated to provide basic raw materials such as ethylene, propylene, butylene, butadiene, benzene, toluene, xylene, naphthalene, etc. From these basic raw materials, various basic organic raw materials such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol, etc. can be produced.

[0003] In the petrochemical process, a corresponding reaction process in the kettle is included. There is a petrochemical reactor with a Chinese patent publication number of CN220425337U. The movement of the telescopic rod drives the push rod and two racks to move, and the movement of the two racks drives the two gears to rotate, so that the reactor tank body rotates with the fixed axis as the center of the rotation axis, so that the reactor tank body flips toward the support, and the inclination angle of the reactor tank body can be adjusted so that the open end of the reactor tank body is parallel to the ground. The position of the open end of the reactor tank body is adjusted, and the height can be lowered, so that it is convenient for the staff to use the cleaning tool to deeply clean the inner wall of the reactor tank body, which is more convenient to use.

[0004] However, since the device lacks gas treatment in the kettle when in use, the internal pressure changes, which affects the kettle itself and the reaction progress, and has poor reliability. Utility Model Content
