Dechlorinating and desulfurizing device used in aromatization process, and use method thereof

Abstract

The invention discloses a dechlorinating and desulfurizing device used in an aromatization process. The device comprises a first input pipe, a second input pipe, an output pipe and a reaction kettle,wherein the first input pipe, the second input pipe and the output pipe are respectively communicated with the reaction kettle, check valves are arranged on the first input pipe, the second input pipeand the output pipe, a first shell with an opening in one end is arranged on the first input pipe, the device further comprises a third input pipe connected with the first input pipe through threads,the third input pipe is provided with a second shell with an opening in one end, a plurality of telescopic rods fixedly connected with the second shell are arranged on the inner wall of the second shell, the device further comprises a pressing plate with a through hole formed in the middle, the pressing plate is fixedly connected with the telescopic end of the telescopic rod, a refrigerating mechanism is arranged in the second shell, the outer wall of the first shell is fixedly connected with a plurality of first through pipes communicating with the first shell, and the outer wall of the second shell is fixedly connected with a plurality of second through pipes communicating with the second shell. According to the invention, with the dechlorinating and desulfurizing device, the sealing performance of the pipeline joint can be effectively improved, the pipeline members can be rapidly separated, and the disassembling efficiency is improved.

Description

technical field [0001] The invention relates to the field of aromatization reaction, in particular to a dechlorination and desulfurization device used in the aromatization process and a use method thereof. Background technique [0002] The original dechlorination and desulfurization process mostly adopts a proprietary hydrogenation device. After the raw material is heated up through the heating furnace, hydrogen is fed under the action of a catalyst, so as to achieve the purpose of reducing the chlorine content and sulfur content in the raw material. However, in the process of feeding hydrogen Among them, due to the tightness of the pipe joints, gas leakage often occurs. Because hydrogen is flammable and explosive, it is easy to cause safety accidents. The existing sealing device has a complex structure, and most of the time it needs to use sealant Spraying on the joints of the pipes, it is troublesome during the disassembly process, and it is not easy to replace when the pi...
