Automatic catalyst circulation type photocatalytic nitrogen fixation reactor

Abstract

The invention discloses an automatic catalyst circulation type photocatalytic nitrogen fixation reactor which comprises a reactor shell, an air inlet is formed in the outer lower end of the reactor shell, an aeration device is arranged at the inner bottom of the reactor shell and connected with the air inlet, and a middle shaft extending in the height direction of the reactor shell is arranged on the aeration device. The middle shaft is sleeved with at least one catalyst recovery device, the upper end of the middle shaft is further sleeved with a sleeve, the upper end of the sleeve extends out of the reactor shell and is connected with a driving device, a plurality of ultraviolet lamp tubes are further arranged in the reactor shell around the inner side wall of the reactor shell, coils are wound on the catalyst recovery devices, and the coils and the ultraviolet lamp tubes are electrified. According to the automatic catalyst circulation type photocatalytic nitrogen fixation reactor, the catalyst recovery device capable of being automatically opened and closed is arranged in the reactor, automatic recovery and cyclic utilization of the catalyst are achieved, convenience and rapidness are achieved, the problem that the catalyst is difficult to recover in photocatalytic nitrogen fixation technology application is solved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic nitrogen fixation, and relates to a catalyst automatic circulation type photocatalytic nitrogen fixation reactor. Background technique [0002] Ammonia is an indispensable and important raw material for industrial and agricultural production in modern society. Photocatalytic nitrogen fixation (synthetic ammonia) can be carried out at normal temperature and pressure, the process is simple, the raw materials are cheap and easy to obtain, and the cost is low. It is a green and environmentally friendly new technology for ammonia synthesis. However, the practical application of photocatalytic nitrogen fixation technology is difficult to recover the catalyst, which seriously restricts the application and development of this technology. To solve the problem of catalyst recovery, the commonly used solution is to fix the catalyst on some supports, such as activated carbon, zeolite, etc. However, th...
