How to heat a single layer glass reactor and what are the characteristics of a double layer glass re

The single-glazed reactor is heated by an oil bath or an electric heating jacket. The oil bath is now intelligent and digitally displayed, which can be kept at a constant temperature, and the temperature is quickly raised and the temperature control is accurate. Generally, the small single-layer glass reactor body is round, and the 100L is barrel-shaped.

The heating bath of the single-layer glass reactor can also be equipped with a cooling coil to shorten the cooling time.

The heating of the double-layer glass reactor is realized by the thermal circulation of the high-temperature and constant temperature circulating oil bath. There are two types of high-temperature circulating oil baths: 200 degrees and 300 degrees. Customers can order according to the requirements of use.

The high-temperature circulating oil bath can be equipped with a cooling coil to shorten the cooling time. If the material will dissipate heat and the temperature will rise during the reaction, you can use an air-cooled high-temperature constant temperature circulating oil bath to take away the heat in the reaction process and maintain a constant temperature.

The single-layer glass reactor directly heats the reaction kettle body through the silver film heating sheet, so that the materials in the reactor are heated at a constant temperature, and stirring can be provided. The material is reacted in the reaction kettle, and the evaporation and reflux of the reaction solution can be controlled, and after the reaction is completed, the single-layer glass reactor lid and the motor part are mechanically lifted (optional electric lifting), and the kettle body can rotate 360 degrees to facilitate the dumping and discharging of materials.

The working principle of the single-layer variable frequency speed regulating glass reactor: under the condition of setting constant temperature, stirring and reaction are carried out under atmospheric pressure or negative pressure in a closed glass container, and the evaporation and reflux of the reaction solution can be controlled.

There are several schemes for electric heating of the reactor: 1. The reactor is jacketed, and it can be circulated with electric heating wire or electromagnetic bucket heater and Zhuhui thermal conduction oil. 2. Direct electric heating outside the reactor.

This makes the electromagnetic heater more suitable. The coil of the electromagnetic heater is wound on the reactor, and the magnetic field generated by the coil directly acts on the reactor to heat up the reactor itself. When the power is sufficient, the heating temperature is about 450-550 degrees, the temperature is adjustable and controllable, and the service life is more than 5 years.

1. All glass parts should be cleaned before installation. 2. A small amount of vacuum silicone grease should be coated on each standard mouth, ball grinding port and sealing surface to increase air tightness. 3. Please be sure to read all the contents of this manual before installation, use, maintenance and inspection, and use it correctly.

4. The power supply voltage must be consistent with the provisions of this instrument. 5. No-load should not run at high speed. 6. The life of the electrical box has a great influence on the surrounding temperature and humidity.

1. Carefully check the instrument before use, whether the glass bottle is damaged, whether the interfaces are consistent, and pay attention to handling gently.

2. Wipe each interface with a soft cloth, and then apply a little vacuum grease.

3. The interfaces should not be tightened too tightly, and the network should be loosened regularly to avoid the connector biting due to tight locking.

4. Turn on the power switch first, and then let the machine run from slow to fast, and use the machine to stop when it is stopped, and then turn off the switch.

5. The PTFE switch everywhere can not be tightened too hard, and it is easy to damage the glass.

6. After each use, you must use a soft cloth to wipe off all kinds of oil stains, stains, and solvents left on the surface of the machine, and keep it clean.

7. After the shutdown, the PTFE switch will deform the PTFE piston when it is stationary in the working state.

8. Clean the sealing ring regularly.

9. The electrical part must not be flooded, and it is strictly forbidden to be damp.

10. The original authentic accessories must be purchased, and the use of other accessories at will will cause fatal damage to the machine.

11. When doing any repair or inspection of the machine, be sure to cut off the power supply and water source first.

The operating temperature of the glass-lined reactor is high, and usually the chemical reaction needs to be carried out under a certain temperature condition, so the reactor can withstand both pressure and clear temperature. There are usually several ways to get high temperatures:

1. Water heating: It can be used when the temperature is not high, and the heating system has two types: open type and closed type before Youmeng. When using high-pressure water, the mechanical strength of the equipment is high, and the outer surface of the reactor is welded with a snake tube, and the snake tube has a gap between the snake tube and the wall of the kettle, so that the thermal resistance increases and the heat transfer effect decreases.

2. Steam heating: when the heating temperature is below 100, it can be heated with steam below one atmosphere; 100 180 range, with saturated steam; When the temperature is higher, high-pressure superheated steam can be used.

3. Heating with other media: If the process requires operation at high temperature or to avoid the use of high-pressure heating system, other media can be used instead of water and steam, such as mineral oil (275 300), diphenyl ether mixture (boiling point 258), molten salt (140 540), liquid lead (melting point 327), etc. Zhiru.

4. Electric heating: the resistance wire is wound on the insulation layer of the reactor cylinder, or installed on the special insulator at a certain distance from the reactor, so that a small space gap is formed between the resistance wire and the reactor body. The first three methods need to add a jacket on the kettle body to obtain high temperature, and due to the large amplitude of temperature change, the jacket and the shell of the kettle are subjected to temperature change and produce temperature difference pressure.

When electric heating is adopted, the equipment is lighter and simpler, the temperature is easier to adjust, and there is no need for pumps, furnaces, chimneys and other facilities, it is very simple to start, the danger is not high, the cost is low, but the operating cost is higher than other heating methods, and the thermal efficiency is below 85%, so it is suitable for the heating temperature below 400 and the place where the electric energy is low.

The glass reactor is far awayInfrared heating, steam heating, water bath circulating heating, heat transfer oil heating or heat transfer oil electric heatingand other heating methods. It is mainly heated by circulating steam in the oil, by welding the jacket outside the kettle, or directly inserting an electric heating tube into the jacket.

Glass reactors are widely used in chemical industry, food, coatings, hot melt adhesives, silica gel, paints, pharmaceuticals, petrochemical production of reaction, evaporation, synthesis, polymerization, saponification, sulfonation, chlorination, nitrification and other processes of pressure vessels, such as reactors, reactors, decomposition pots, polymerization kettles, etc. The reactor is mainly composed of four parts: the inner tank, the jacket, the stirring device and the supporting seat (the insulation structure can be used according to the process needs).

The double-glazed glass reactor of Shanghai Sinovac Instrument is simple and convenient to operate, with transparent glass design, the reaction process is clear at a glance, and it is also more convenient to control. The following are the three most common heating methods sorted out by Sinovac Instrument, I hope it can help you.

1. Steam heating: When the heating temperature is below 100, steam can be used to heat the double-layer glass reactor. When the temperature requirement is in the range of 100-180, saturated steam can be used, and when the temperature requirement is higher, high-pressure superheated steam can be used to stop heating;

2. Electric heating: electric heating is wound on the insulation layer of the double-glazed reactor cylinder through the resistance wire, or installed on the special insulator at a certain distance from the double-glazed reactor. Therefore, a small gap can be formed between the resistance wire and the double-layer glass reactor body;

3. Water heating: When the temperature requirement is not high in the consumption process, the heating can be stopped by water heating;

At present, the most mainstream is to use water or mineral oil to stop heating, because of its low cost, easy to change the medium, easy to maintain the characteristics of the choice of Fangda customers.

1. Check whether the power supply voltage is consistent with the specifications provided on the nameplate of the machine.

2. Plug in the power plug, turn on the power switch on the inverter, and use the speed control knob to select the appropriate speed.

3. The flow of materials and the power of the motor speed may resonate at a certain point, please change the speed of the motor to avoid resonance.

4. After the stirring rod is installed, you must rotate it by hand, pay attention to whether the concentricity is good, as if the centricity is not good, you should loosen the heavy clamp, turn on the power supply after clamping, and gradually adjust it from slow to fast 5. Use the stirring rod adjuster to make the stirring leaf up and down 5cm as needed.

6. If you find that the sealing performance of the kettle is reduced, please check the rotating bearing in the stirrer sleeve.

7. The glass instruments of this reaction device are all made of high-quality borosilicate glass with low expansion coefficient and high temperature resistance.

8. The laminated layer on the glass kettle is connected to the external circulation port, and the hot oil can be used for heating reaction, and the coolant can be used for low-temperature reaction.

9. When the test is carried out at low temperature, the discharging valve at the bottom will be frosted, and the valve must be partially thawed first to prevent the glass from being broken.

10. If there are particulate objects in the solution during use, there may be residues on the PTFE piston of the valve when discharging, and the air tightness will be affected when used again.
