Protector of photocatalytic reaction system

Abstract

The invention discloses a protector of a photocatalytic reaction system. The protector comprises a box and a light source bracket. The box comprises a box body, an upper front cabin door, a lower front cabin door and a rear cabin door. The box body has an upper space and a lower space. The upper space is divided into a sealing layer and an operation layer. The sealing layer is sealed through the rear cabin door and is used for installing a system main-body of the photocatalytic reaction system. The operation layer is sealed through the upper front cabin door and is used for installing a system valve group of the photocatalytic reaction system. The lower space is sealed through the lower front cabin door and is used for installing a reactor of the photocatalytic reaction system. The lower front cabin door is provided with a light window. The light source bracket is installed at a position corresponding to the light window and is used for installing a light source of the photocatalytic reaction system. The box is provided with an inert gas filling mechanism which is used for filling the sealing layer, the operation layer and the lower space with an inert gas. According to the invention, a stable reaction and testing environment can be provided for the photocatalytic reaction system under the condition of negative pressure, and influence of the environment on an photocatalytic reaction and a test is minimized.

Description

technical field [0001] The invention relates to the technical field of photocatalysis, in particular to a protective device for a photocatalytic reaction system. Background technique [0002] With the increasing energy crisis and environmental pollution, the new energy system has attracted more and more attention from various countries. The use of photocatalytic reaction system to produce hydrogen is an important method to obtain hydrogen energy, and the research on photocatalytic reaction system has attracted more and more attention. The photocatalytic reaction system generally includes a gas circulation unit, a detection unit, a separation unit, a light source, and a reactor. The gas circulation unit, the detection unit, and the separation unit constitute the main body of the system, and are installed as a whole through a glass shell. There are system manifolds for controlling the main body of the system. [0003] The existing photocatalytic reaction system is generally ...

Problems solved by technology

In the prior art, a vacuum glove box (nitrogen protection box) is used to seal the reaction system, which can provide a protective atmosphere for the system. However, due to the particularity of the structure and operation of the system, the general vacuum glove box (nitrogen protection box) does not work well with the system. Matching so as to affect the system operation and affect the reaction process and results, such as the placement of the system light source, the connection of various pipelines and external facilities in the system, the particularity of the operation process, etc.
