Lab Scale High Pressure Reactor

The lab scale high pressure reactor is used for chemical, high-temperature and high-pressure synthetic reactions or catalytic reactions, and it is necessary to simultaneously measure pressure, temperature, measure speed and add inert gas protection, stabilize the pressure and realize the experimental environment under the conditions of on-line sampling or on-line feeding. . It is suitable for photochemical high-pressure reaction, carbon dioxide CO2 reduction, carbon dioxide CO2 reduction to methanol, carbon dioxide CO2 reduction to methane CH4, reduction and degradation of nitrogen oxides, high-pressure photocatalytic degradation of formaldehyde and other fields.

High pressure autoclave reactor is a typical innovation of magnetic transmission device applied to reaction equipment. It fundamentally solves the problem of shaft seal leakage that cannot be overcome by packing seals and mechanical seals before, without any leakage and pollution. The most ideal device for reaction, especially for chemical reactions with flammable, explosive and toxic media, shows its superiority even more.

What Are the Advantages of Lab Scale High Pressure Reactors over Ordinary Reactors?

The lab scale high pressure reactor and the ordinary reactor belong to the category of the reactor, but the material composition of the two is not the same.

The body material of the lab scale high pressure reactor is mainly made of 1cr18Ni10Ti stainless steel, and titanium (TA2), nickel (Ni6) and composite steel plates can be made according to different media requirements. The body structure has flat cover, convex cover and closed type with manhole. The opening of the reaction kettle body and the kettle cover can be designed according to the user's requirements; the heating methods include jacketed steam, jacketed hot oil and electric heating, etc., which can be optionally selected by the user when ordering. For the internal surface of the kettle that requires polishing, it can achieve the above-mentioned mirror polishing level. For high-viscosity materials, it can be processed into a conical bottom, which is convenient for discharging and cleaning.

The materials of ordinary reactors generally include carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel) alloys and other composite materials. The reaction kettle can be made of stainless steel materials such as SUS304 and SUS316L. Agitators include anchor type, frame type, paddle type, turbine type, scraper type, and combined type. The rotating mechanism can adopt cycloidal pinwheel reducer, stepless variable speed reducer or frequency conversion speed regulation, etc., which can meet the special requirements of various materials. response request.

Common reaction kettle sealing devices can adopt mechanical seals, packing seals and other sealing structures. Heating and cooling can use jacket, half pipe, coil, Miller plate and other structures. The heating methods include: steam, electric heating, heat transfer oil, to meet the needs of different working environments such as acid resistance, high temperature resistance, wear resistance, and corrosion resistance. Craft needs. Moreover, it can be designed and manufactured according to the user's process requirements.

Precautions for the Use of Lab Scale High Pressure Reactors:

1. Sealing Performance

The autoclave is a precision equipment. The sealing ring adopts the contact sealing form of the cone surface, and the purpose of sealing is achieved by tightening the main bolts to make them compress each other. Therefore, special protection must be given to the sealing cone to avoid damage caused by various collisions. When installing the cover, first place the reactor body, and then carefully install the cover on the kettle body at a fixed position. When tightening the main bolts, they must be tightened diagonally and symmetrically for several times. Evenly, the kettle cover is not allowed to tilt to one side to achieve a good sealing effect, and the specified tightening torque should not be exceeded to prevent the sealing surface from being squeezed or accelerated wear. All threaded connections need to be coated with oil or oil mixed with graphite during assembly. If the sealing surface is damaged, it needs to be reprocessed to restore good sealing performance.

2. Sealing Operation

The air inlet and the exhaust valve are sealed with a needle valve. When closing, you only need to turn the valve needle slightly to press the tight surface to achieve a good seal. Excessive force is prohibited to avoid damage to the sealing surface.

3. Temperature Rise and Pressure Test

Before use, the autoclave should be heated and pressurized for a tightness test. Air and nitrogen can be used as the test medium, but inert gas is preferred. Oxygen or other flammable and explosive gases are strictly prohibited. The temperature and pressure increase must be carried out slowly. The heating rate is not more than 80 degrees per hour. During the pressure test, connect the inlet valve of the autoclave to the compressor (or high-pressure pump) with a connecting pipe. The pressure increase must be carried out in stages, with 20% of the working pressure as the interval, and stay for 5 minutes for each step up, and stay for 30 minutes when it reaches the test pressure, and check the sealing condition. The test pressure is 100-105% of the working pressure. If a leak is found, the pressure should be lowered first, and then the nuts and joints should be properly tightened. It is strictly forbidden to tighten the nuts and joints under high pressure.

4. Cooling Process

Rapid cooling and rapid heating are prohibited during the reaction process to prevent excessive temperature stress from causing cracks in the kettle body. After the reaction is over, cool down first, and cool it with water (exothermic reaction) or air cooling, then release the high-pressure gas in the kettle to reduce the pressure to normal pressure, and then unscrew the bolts symmetrically and evenly. In the process of opening the lid, special attention should be paid to protecting the sealing surface, and the kettle lid should be lifted evenly to avoid damage to the sealing ring of the kettle lid and the kettle body due to collision.

5. Subsequent Processing

After each operation, the residue on the kettle body and the lid should be removed. All sealing surfaces on the autoclave should be cleaned frequently and kept dry. Hard objects or soft objects with rough surfaces are not allowed to clean.

Maintenance Method of Lab Scale High Pressure Reactor:

1. In the process of use, the regulations on cooling, oil filling, etc. should be strictly followed, and the maintenance and maintenance of the lab scale high pressure reactor should be done well.

2. You should regularly check whether each pipe fitting and fastener is loose and tight, and check whether each instrument is malfunctioning.

3. Clean the small lab scale high pressure reactor every time you finish the experiment. When cleaning, do not touch or scratch the sealing surface. If there is dirt on the sealing surface, you should use the corresponding cleaning agent, and use Wipe clean with a soft cloth.

4. When not in use, it should be kept clean without stains or solvent residues, and the bolts and valves should be kept loose.

5. During daily use, it should be operated strictly according to the working pressure and working temperature marked on the product nameplate, so as to avoid danger.

6. When all the valves of the lab scale high pressure reactor are in use, the valve stem (needle) should be slowly turned, and the cover should be pressed tightly to achieve the sealing effect. It should also be turned slowly when closing to avoid damage to the sealing surface.
