Titanium reactor design points

Titanium reactors can be employed to corrosive experiments. Titanium is a very active but easily passivised passivation. The passivation layer remains relatively stable and is usually used in reactions with corrosive materials. Because of its high specific strength, heat resistance, corrosion resistance and fracture toughness, etc. therefore, the titanium reactor in the aviation, aerospace, petrochemical, medical and geological fields is greatly favored. Titanium reactor design compact and simple, easy to use, a machine can achieve heating and cooling reaction, and can be stirred. More efficient, better yield, less costly. Accessories include temperature probe, pressure gauge, inlet valve, sampling valve, exhaust valve, mixing device, cooling and heating device, should container, mixer and transmission system, cooling device, safety device, heating furnace and other components.

1. Kettle body, kettle cover constructed of titanium processing, kettle body connected by threads and flanges, kettle cover for the flat plate cover, both by the circumferential uniform bolt, nut fastening connection.

2. The main seal of the reactor adopts type A double seal, the other sealing points adopt the seal form of circular arc and plane, circular arc and arc surface, and rely on the high precision and finish of the contact surface to reach Good sealing effect.

3. Kettle body equipped with barrel-type silicon carbide furnace, electric furnace were worn in the furnace core, the end of the furnace shell from the lower side of the piercing through the studs, rubber cables and the controller connected.

4 kettle covers equipped with a pressure gauge, burst membrane safety devices, vapor-liquid phase valve, temperature sensor, easy to keep abreast of the reactor to understand the situation, adjust the proportion of the media inside the reactor, and ensure safe operation.

5. Bearings with titanium or titanium alloy bearing high-strength graphite, abrasion resistance, and long maintenance cycle.

Titanium reactor need to pay attention to the following:

1. Before using the refrigerant inlet valve must be closed,;

2 start the blender, and then enter the material, and then open the steam valve and electric heating; 3 to reach the required temperature, you should turn off the steam valve and electric heating, after 2 to 3 minutes, then off the blender; 4 after the end of processing , Let the titanium reactor kettle and the jacket after the remaining condensate, rinse with warm water as soon as possible, and then with 40 ~ 500C alkaline water in the container wall cleaning, in order to achieve the purpose of durability. Special pot without material (heat-absorbing medium) empty pan case, shall not open the steam valve and electric heating, 5 special attention to the use of steam pressure, shall not exceed the rated working pressure III: Corrosion effect on titanium

Acid

Titanium reactors have excellent corrosion resistance to acids, including organic acids, inorganic acids, and acidic materials that oxidize and restore. In the practice of consumption will be issued as part of the reaction rate, chemical grade and other effects. But to remind everyone hydrochloric titanium reactor has a strong corrosive, strong concentration of phosphoric acid on the reactor also has a strong corrosive. When the phosphoric acid concentration reaches 95%, the maximum operating temperature is 95 degrees Celsius.

Alkali

Alkaline materials are more corrosive to titanium reactors than acidic ones. Corrosivity increases as concentration increases. Temperature also affects corrosiveness, and corrosion rates double for every 10 degrees Celsius increase in temperature. Therefore, the use of hot alkali, we must take care operation.

Water

Titanium water reactors are also slightly corrosive. Under normal conditions, the kettle should have a durable corrosion resistance to water. At lower temperatures, the water forms a condensate and the condensate produces basic ions that form a slightly acidic material. In such a situation, we usually advocate the use of uncapped containers to lower the acid content.

Titanium reactor currently on the market can be divided into pure titanium reactor, composite titanium reactor, titanium liner reactor three categories, was used in different process environments. Which composite titanium reactor because of its superior performance, the price is less than titanium reactor, the application is more extensive.

1. Titanium reactor stirring method: the use of strong magnetic cylindrical rotary coupling structure, stirring speed of 0 ~ 1000r / min, and according to user needs to adjust the mixing capacity.

2. Titanium reactor material: Titanium reactor is mainly made of titanium composite materials, special requirements, can be lining treatment to improve the anti-corrosion ability of the material.

3. Titanium reactor heating method: the use of electric heating. Titanium reactor can also be based on customer is required to provide electric heating type, liquid heating type, electric, liquid heating type.

4. Titanium reactor mechanical and connection structure: the connection structure using a bolt-type structure or quick-open snap ring connection, while the kettle cover can be upgraded, kettle body can pour out or under the material.
