Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a gas dust removal mechanism of a reactor. Background Art

[0002] The reactor is a device that realizes the reaction process. It is used to realize liquid single-phase reaction processes and liquid-liquid, gas-liquid, liquid-solid, gas-liquid-solid and other multiphase reaction processes. It is widely used in chemical, oil refining and other industrial sectors. The reactor is needed when carrying out methane oxidative coupling reaction.

[0003] After searching, a Chinese patent with announcement number CN213019687U discloses an automatic purge of a catalytic reactor. The above patent realizes the dust purge function by setting a purge nozzle structure at the bottom of the annular positioning air duct, but its dust removal mechanism is arranged on the upper part of the furnace body, resulting in too low purge force at the bottom of the furnace body, thereby reducing the dust removal effect. In order to advance the industry technology, better realize the dust removal function and improve the competitiveness of core technology, this application proposes a new implementation plan that is different from the prior art. Utility Model Content

[0007] Furthermore, the outer walls of the air inlet pipe and the air outlet pipe are sleeved with a heat exchanger.

[0008] Furthermore, the outer walls on both sides of the tank body are fixedly connected with lifting ears.

[0009] Furthermore, a plurality of supporting legs are fixedly connected to the bottom of the circumferential outer wall of the tank body.

[0010] Furthermore, an explosion-proof port and a sampling port are provided on one side of the tank body.

[0011] Furthermore, a sealing ring is clamped on the top of the tank body, and the sealing ring is sleeved with the output end of the motor.

[0012] Furthermore, a catalyst fixing frame is fixedly connected to the inner wall of the bottom of the tank body.

[0013] The beneficial effects of the utility model are:

[0014] 1. By rotating the bidirectional screw driven by the motor, the lifting ring is driven to move, and then moves along the inner wall of the tank, thereby avoiding too low a blowing force at the bottom of the furnace body and improving the dust removal effect.

[0015] 2. The output end of the motor and the tank body are sealed by a sealing ring to improve the practicality of the tank body. BRIEF DESCRIPTION OF THE DRAWINGS
