Description
Technical field
The utility model relates to the reaction unit field, particularly a kind of small testing device that carries out gas-liquid-solid three-phase or gas-liquid two-phase oxidation reaction in the laboratory.
Background technology
At present the still reaction device that gas-liquid-solid three-phase or gas-liquid two-phase oxidation reaction adopt four-hole bottle more is carried out in the laboratory, namely inserts a bottom insert canal in the four-hole bottle, carries out simple bubbling oxidation reaction.Because this simple bubbling device carries out in four-hole bottle, there be the liquid holdup of gas dispersion in liquid phase and the border contact surface is little mutually, the problem that mass transfer and heat transfer efficiency are low, central authorities at the bottom of gas distributor can only adopt a simple bottom insert canal to be insinuated into bottle when simultaneously the four-hole bottle structure made experiment have hindered the even distribution of gas between liquid layer.As increasing air capacity, not only there is punching material phenomenon in four-hole bottle, and the system inner fluid is reacted in plunger bubbly flow district all the time, affects reaction effect, causes experimental repeatability very poor.
The utility model content
The technical problems to be solved in the utility model is to adopt the still reaction device of four-hole bottle for oxidation reaction in the prior art, causes the poor problem of experimental repeatability, and the small testing device of a kind of simple and effective gas-liquid-solid three-phase or gas-liquid two-phase oxidation reaction is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is:
A kind of experiment oxidation reaction apparatus is comprised of oxidizing tower 1, condenser pipe 2, electric heating earthen 3, air pump 4, soft silicone tube 5, aerate head 6, punching plug 7, glass tube 8, thermometer boss 9 and vomit pipe 10; Wherein condenser pipe 2 is connected with the upper end of oxidizing tower 1, glass tube 8 is placed in the oxidizing tower 1 and with oxidizing tower 1 and is connected by punching plug 7, glass tube 8 lower ends are connected by soft silicone tube 5 with aerate head 6, and oxidizing tower 1 lower end is provided with thermometer boss 9, and oxidizing tower 1 bottom is provided with vomit pipe 10.
Gas-liquid-solid three-phase or gas-liquid two-phase reaction are finished in oxidizing tower 1.
Oxidizing tower 1 described in the utility model is the there-necked flask of 1000～2000ml by the upper end, the long 1000～1500mm that the lower end connects, and the straight glass tube of diameter 65～70mm forms.
Aerate head 6 described in the utility model is the glass envelope that glass tube 8 lower ends connect, and is distributed with aperture on the glass envelope.
As preferably, aerate head 6 is the glass envelope of a diameter 28mm of glass tube 8 lower ends connection, be evenly distributed 12 apertures on the glass envelope, the aperture is 0.5mm or is the glass envelope that diameter is 30mm that glass tube 8 lower ends connect, be evenly distributed 12 apertures on the glass envelope, the aperture is 1.0mm or is the glass envelope that diameter is 30mm that glass tube 8 lower ends connect that be evenly distributed 16 apertures on the glass envelope, the aperture is 0.5mm.
During oxidation reaction, liquid reactions material and catalyst are put into oxidizing tower 1, and liquid level terminates in oxidizing tower 1 middle part or 2/3rds places, passes into cooling water to condenser pipe 2, then opens air pump, and gas enters aerate head by glass tube.According to reaction physical property and reaction process condition, select suitable aerate head, control Air Bubble Size and distribution form make gas be able to even distribution in oxidizing tower inside.Then heat by the electric heating earthen in the oxidizing tower outside, control certain reaction temperature, oxidation reaction is carried out smoothly.
Advantage of the present utility model and effect are:
The utility model device is to the material wide adaptability, install simple, can change aerate head according to different material properties, reaction system, process conditions, size with the control bubble, adjust the distribution of gas in system, strengthen to greatest extent the liquid holdup of gas in liquid phase and contact with the phase border, make mass transfer and conduct heat more effective.The there-necked flask that the oxidizing tower upper end arranges is the gas expansion section, and waste gas can be discharged rapidly, can prevent from rushing material simultaneously and free.Because this device dismounting is simple, applying flexible, the oxidation technology that is highly suitable for carrying out in the laboratory is explored experiment.
