Background
Photochemical and photocatalytic oxidation methods are currently a more studied advanced oxidation technology. The photocatalytic reaction is a chemical reaction that proceeds by the action of light. Photochemical reactions require molecules to absorb electromagnetic radiation of a particular wavelength, be excited to produce a molecular excited state, and then undergo a chemical reaction to produce a new species, or become an intermediate chemical product that initiates a thermal reaction. The activation energy of photochemical reaction is derived from the energy of photons, and photoelectric conversion and photochemical conversion are always active research fields in the utilization of solar energy.
Photocatalytic oxidation technology utilizes photo-excitation oxidation to oxidize O2、H2O2The oxidizing agent is combined with the light radiation. Photodegradation generally refers to the gradual oxidation of organic substances into low-molecular intermediate products under the action of light to finally generate CO2、 H2O and other ions, e.g. NO3 -、PO4 3-、Cl-And the like. The photodegradation of organic substances can be divided into direct photodegradation and indirect photodegradation. The former is a chemical reaction that occurs further after the organic molecules absorb light energy. The latter is a reaction in which some substances existing in the surrounding environment absorb light energy to form an excited state and then induce a series of organic pollution. Indirect photodegradation is more important for organic pollutants that are difficult to biodegrade in the environment. The way of degrading pollutants by photochemical reaction includes photochemical oxidation process without catalyst and with catalyst. The former mainly adopts oxygen and hydrogen peroxide as oxidants, and pollutants are oxidized and decomposed under the irradiation of ultraviolet light; the latter is also known as photocatalytic oxidation and can be generally classified into two types, homogeneous and heterogeneous catalysis. The common method in homogeneous photocatalytic degradation is Fe2+Or Fe3+And H2O2As a medium, OH is generated by the photo-Fenton reactionPollutants are degraded, and in heterogeneous photocatalytic degradation, a certain amount of photosensitive semiconductor materials are added into a pollution system, and a certain amount of light radiation is combined, so that the photosensitive semiconductor is excited under the irradiation of light to generate electron-hole pairs, dissolved oxygen, water molecules and the like adsorbed on the semiconductor react with the electron-hole pairs to generate free radicals with strong oxidizability such as OH and the like, and then the pollutants are completely or nearly completely mineralized through hydroxyl addition, substitution and electron transfer between the pollutants.
The photochemical tubular reactors commonly used in laboratories at present all adopt a single-tube reactor made of high borosilicate glass or quartz glass to realize experiments, and are mainly convenient for light transmission and difficult to generate pollution in the reaction process. The structure of the single-tube reactor comprises the following structures:
1. firstly, a single-tube quartz reactor is a quartz straight tube, and in order to fill a catalyst, a temperature measuring thermocouple is fixed at the center of the reactor, then inert substances such as quartz sand and the like are filled at the bottom of a reaction area to be used as supports, then the weighed catalyst is put in from the top, and a bed layer is uniform by knocking the tube wall. The reactor has the advantages of simple structure, low price and easy cleaning, and the temperature measuring thermocouple can detect the center of the reaction zone. Because the pipe is a whole pipe, no welding deformation exists, and the pressure resistance is good. The defects that the catalyst is very troublesome to fill, the catalyst is not uniformly distributed and is difficult to control due to the high-altitude putting, and the repeatability of multiple experiments is poor; the inert material powder at the bottom is easy to block a subsequent pipeline; the catalyst has small light receiving area and uneven illumination; the contact area of the catalyst and the airflow is small and the airflow is not uniform. The new catalyst in the scientific research field is generally difficult to manufacture or expensive, the experimental dosage of the catalyst is large, the utilization rate of the catalyst is low, and the new catalyst in the scientific research field is generally difficult to manufacture or expensive;
2. for filling convenience and increasing the light receiving area, the common reactor is a flat tube reactor: namely, a reaction area in the middle of a quartz straight pipe is made into a flat pattern, and a sand plate is welded below the reaction area; the advantages of the flat tube reactor: the sand plate can save most of the filling time, so that the problem that the inert material powder at the bottom easily blocks a subsequent pipeline is solved; the flat reaction zone can thin the catalyst, reduce the catalyst consumption, and increase the illumination area. But simultaneously, a plurality of defects are added, such as that the temperature measuring thermocouple can only be placed below the sand plate and can not measure the central temperature of the reaction area. If the temperature is measured, the illumination is shielded, and the catalyst is very troublesome to fill; after the reaction is finished, the catalyst must be poured out from the upper opening, the catalyst remained on a sand plate is difficult to clean, gas circuits are easy to block, new catalyst is easy to pollute, and the experimental repeatability is poor; both the flat reaction zone and the sand plate have internal stress during welding, and the pressure resistance is poor. The catalyst bed is still high and has poor gas permeability. Catalyst filling is still put in from the top, the bed layer is even by knocking the pipe wall, the reactor is fragile, and potential safety hazards exist.
In view of the above-mentioned defects of the existing photochemical single-tube quartz reactor, the present inventors have made active research and innovation to create a double-tube reactor with a novel structure, so that it has more practicability.
