Discharging structure, adsorbent circulating unit and adsorption desulfurization device

Abstract

The invention relates to the technical field of petrochemical industry, and discloses a blanking structure, an adsorbent circulating unit and an adsorption desulfurization device. The blanking structure comprises a first blanking flow path (1) and a second blanking flow path (2) which are used for blanking of the regenerator (0), a feeding port of the second blanking flow path (2) is located above a feeding port of the first blanking flow path (1), and when blanking at the feeding port of the first blanking flow path (1) is blocked, materials in the regenerator (0) are blanked from the second blanking flow path (2). According to the discharging structure, continuous discharging can be guaranteed, and then the adsorbent circulating unit using the discharging structure can be continuously and stably carried out.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a feeding structure, an adsorbent circulation unit and an adsorption desulfurization device. Background technique [0002] S Zorb unit mainly includes four parts: feed and desulfurization reaction system, adsorbent regeneration system, adsorbent circulation system and product stabilization system. The feed and desulfurization reaction system is to heat the raw gasoline and hydrogen and then vaporize them and send them to the reactor for desulfurization reaction; the adsorbent regeneration system is to oxidize and regenerate the adsorbent that has adsorbed sulfur in the regenerator to restore its desulfurization activity; The adsorbent circulation system sends the adsorbent in the reactor to the regenerator, and then sends the regenerated adsorbent in the regenerator to the reactor to complete the reaction-regeneration cycle of the adsorbent; the product stabilizati...

AI Technical Summary

Problems solved by technology

[0003] The current problem is that the adsorbent that has been regenerated in the regenerator contains agglomerates during the feeding process, and the cycle of the adsorbent is often interrupted. Even if there is a filter on the regenerator feeding line, filtration will still occur. The clogging of the filter will lead to the interruption of the adsorbent circulation, and it is necessary to stop and clean the filter, so the continuous and smooth operation of the S Zorb device cannot be guaranteed

In order to solve the problem of the above-mentioned interruption of the adsorbent cycle, a new feeding method is provided, which can ensure the continuous and stable operation of the adsorbent cycle.
