Problems solved by technology

Due to the attenuation effect of photon transmission, the direct scale-up method will prevent light from penetrating into the interior of the reaction mixture in the tank reactor
At the same time, in order to fully react the internal reactants, the heat brought by over-exposure and excessive mechanical stirring will form by-products and reduce the reaction yield

Abstract

The invention discloses a photochemical reactor. In the photochemical reactor, a light source provides adjustable optical radiation, and the light source is arranged in a reflection camera obscura; The first gradual change section is located at first end, close to input fluid, of inner pipe wall and has first length and first cross section in longitudinal direction of vortex flow pipe, and first cross section is smoothly and gradually changed into blade shape from circle with radius being R while being twisted by first preset angle in longitudinal direction along with first gradual change section. The first cross section is twisted by first preset angle in nonlinear gradual change mode in longitudinal direction along with first gradual change section, and third cross section is twisted by third preset angle in longitudinal direction along with second gradual change section and is smoothly and gradually changed into circle with radius being R from blade shape. The third cross section is non-linearly and gradually twisted by a third preset angle in the longitudinal direction along with the second gradual change section, the cross section area of the third cross section is kept unchanged, and the measuring unit is arranged in the tubular reaction unit.

Description

technical field [0001] The invention relates to the technical field of photochemical reactions, in particular to a photochemical reactor. Background technique [0002] Today's chemical industry, especially the organic synthesis industry, has become an important boost to social and economic development. Chemical products provide people with all kinds of necessities of life. However, with the current deteriorating environment and insufficient resource reserves, the concept of "green chemistry" for sustainable development has become an important guiding direction for the development of the chemical engineering industry. Photochemical reactions are considered to be a class of reactions applicable to the concept of green chemistry. It uses light energy rather than heat energy to activate molecules, so there is no need to heat to provide energy for the reaction, so that the photochemical reaction can be carried out efficiently and quickly at room temperature. It provides a safe...
