Problems solved by technology

[0003] 1) The light source is placed inside the reaction, which is not conducive to the expansion of the reactor, but also has the potential risk of fire
The temperature of the light source is high, the working environment is harsh, and the life is short;
[0004] 2) The gas absorption and photochemical reaction are in the same equipment, the existence of a large number of bubbles makes the light energy dissipate rapidly, the catalytic efficiency is not high, and the economic cost is increased;
[0005] 3) Since the main component of the reactor is glass and has a complex structure, the operating conditions can only be carried out under normal pressure, so that the oxygen concentration in the reaction liquid is low, and the solvent loss with the exhaust gas is large

Embodiment Construction

[0011] Combine below figure 1 The external circulation type photochemical reaction equipment is described in detail to further understand the present invention, but the following examples are not limitations of the present invention.

[0012] The 20L reaction liquid is injected into the photochemical reactor R101 by the continuous feeding method of 1.25L / hr. The external light source F101 is reflected by the F102 reflector and enters the reactor from the pressure-resistant window on the plane side of R101, which is the photochemical reaction. provide energy. The intensity of the external light source is adjusted by the temperature control X101 according to the reaction requirements. Oxygen enters the oxygen enrichment tower T101 through the air compressor P101, and enters the photochemical reactor through the circulation pump P102 to participate in the photochemical reaction. Among them, a part of the reacted feed liquid in the reactor is collected as a product through the c...

Abstract

The invention discloses outer circulating photochemical reaction equipment. The outer circulating photochemical reaction equipment is mainly composed of an oxygen enrichment tower, a photochemical reactor, an external light source, a cooler and a temperature control system, wherein an external oxygen enrichment tower can reduce the absorption loss of bubbles to the light energy, and the efficiency is improved. The outer circulating photochemical reaction equipment disclosed by the invention has the advantages that the design of the external light source is beneficial to expanding a reactor, the pressure-proof degree of the reaction equipment is improved, the dissolved oxygen in a reaction liquid is increased, and the outer circulating photochemical reaction equipment is beneficial for a circulating reaction and provides a practice instruction for safe, economic and efficient industrialization photochemical reaction.

Description

technical field [0001] The photochemical reaction of this equipment is closely related to our daily life. It is closely related to organic synthesis, life chemistry, material chemistry, environmental chemistry, dye chemistry and many other aspects. Therefore, this equipment has a wide range of applications. Background technique [0002] Photochemical reaction refers to the chemical reaction that a substance generally produces under the irradiation of visible light or ultraviolet light, and is a reaction triggered by the absorption of photons by the molecules of the substance. The process has good selectivity and can be carried out at normal temperature and pressure, so photochemical reactions are widely used in life. However, photochemical reactions still have the following disadvantages: [0003] 1) The light source is placed inside the reaction, which is not only not conducive to the expansion of the reactor, but also has a potential risk of fire. The temperature of the ...
