Bottom irradiating type high temperature and high pressure photochemical reaction kettle

Abstract

The invention discloses a bottom irradiating type high temperature and high pressure photochemical reaction kettle. The bottom irradiating type high temperature and high pressure photochemical reaction kettle is characterized by comprising a case, wherein the case comprises an upper partition plate, the upper partition plate is provided with a heating furnace, a reaction kettle is arranged in theheating furnace, a kettle body of the reaction kettle penetrates through the upper partition plate and extends out, a transparent window made of a sapphire sheet is arranged at the bottom of the kettle, a middle partition plate is fixed in the case, a light source is installed in the case, a lamp holder of the light source penetrates through the middle partition plate, extends upwards and perpendicularly irradiates on the sapphire sheet, a closed dark case for holding the lamp holder and shading for the lamp holder is formed in the case, and a heat dissipation device is arranged. The bottom irradiating type high temperature and high pressure photochemical reaction kettle has the advantages that the illumination intensity is strengthened and the light pollution of the light source on a labis avoided.

Description

technical field [0001] The invention relates to a photochemical catalytic reaction device, in particular to a bottom-illuminated high-temperature and high-pressure photochemical reaction kettle. Background technique [0002] High-temperature and high-pressure photochemical reactor is a common experimental equipment, which is often used for photocatalytic reactions under high temperature and high pressure. During the reaction, a light source is required to irradiate the inside of the reactor, and the use of light to promote and accelerate the chemical reaction of the reaction medium plays a photocatalytic role. . The light transmission area and light intensity will directly affect the reaction efficiency and effect. The larger the light transmission area and the stronger the light intensity, the higher the reaction conversion rate. [0003] Since the temperature of the high-temperature and high-pressure photochemical reaction is generally higher than 150°C and the pressure i...

Problems solved by technology

For example, the Chinese patent with the notification number CN205815670U discloses a photochemical catalytic reactor, which discloses the method of irradiating at the bottom of the reactor. However, this patent only discloses an opening at the lower cover of the reactor, and a lens is installed between the opening and the reactor body. But there is no method of setting the light source, and no specific implementation method is given

[0007] Since the power of the light source used for photocatalysis is generally >300W, the light intensity is 5 times that of the car headlights. During the irradiation process, the light will diverge to the surroundings. On the one hand, the scattered light will lead to the weakening of the light intensity on the reaction medium.

On the other hand, the severe light pollution in the laboratory is unbearable to the researchers. If the researchers wear light pollution protective glasses, it will be extremely inconvenient during the experiment; Both the furnace and the light source have a very high temperature, so the heat dissipation of the protective box is another problem, and the scientific research personnel must observe the reaction situation and perform various operations at any time during the experiment, so the door of the protective box must be opened and closed frequently. not advisable
