Basic structure of high temperature and high pressure photochemical reaction kettle|Basic structure of high temperature and high pressure photochemical reaction kettle

sapphire window high pressure reactor is composed of four parts: the tank, the tank cover, the mirror and the flange cover of the mirror. The tank body and the tank cover constitute the main part of the equipment, which is the place of the medium experiment. The tank body and the tank cover are assembled with the main bolt which is evenly distributed. The opening of the tank cover is provided with a pointer type pressure gauge port and an air discharge port, and an air inlet port is provided with a liquid inlet port, a

sealing surface is very smooth, operating and maintenance should pay attention to protection, if the use of reasonable, can be used more than a thousand times. The main bolt is tightened not overexert, shall not exceed the prescribed tightening torque range of 80~120N.M; and according to the diagonal distribution principle, evenly tighten the bolt tightening in 2~3 times, in order to prevent the crowded bad sealing surface. Loading and unloading tank cover, tohandlegentlyand, sealing surface to prevent collisions, the appearance of scars. After the sealing surface damage, to re repair the polishing, the side can restore the sealing performance. Check whether the pipe fittings and fasteners loose and tight, but also need to check whether the instrument failure.

after the completion of the above work, air tightness test according to the design pressure, medium for nitrogen or other inert gas, prohibited the use of flammable and explosive gas, pressure must be graded, holding 15~30 minutes, there shall be no leakage. Repair and re test after decompression.

equipment control box should be placed in a separate set of dry, sanitary and well ventilated electrical control workshop. The cooling tank is not allowed by heating and fast cooling speed, to prevent the crack caused by thermal stress. When the temperature difference between inside and outside of the tank should be taken into account when the temperature difference between inside and outside of the tank should be taken into consideration, the heating rate should be reduced appropriately. Needle valve line seal, just gently turn the valve needle, the pressure of the close cover, that is, to achieve good sealing, prohibit the use of excessive force, so as not to damage the sealing surface.

Design of a new type of mechanical sealing device for split type|Design of a new type of mechanical sealing device for split type

Design of a new type of mechanical sealing device for split type
production of

laboratory reactor is an important equipment of petrochemical and other industries, is one of the main production equipment of the entire process of chemical industry. The rotary shaft mechanical seal device is one of the reactor and the whole process may be the failure of the most frequent site, once the sealing failure in need of maintenance, integrated mechanical sealing device disassembly trouble and long maintenance cycle, so people have been committed to the research and development department in order to complete the replacement of the split mechanical seal, mechanical seal without dismantling the shaft on parts of the case. But the existing split seal relatively overall seal in the structure to ensure the reliability of sealing problems, thus it is difficult to meet the working environment on the sealing performance requirements of large reactor to work under high pressure and high temperature, corrosion condition is even more so.

Reactor failure phenomena, causes and elimination methods|Reactor failure phenomena, causes and elimination methods

  phenomenon: the kettle cover, the kettle body sealing surface leakage.

;

 

reason: main nut loose; sealing surface damage.

;

 

elimination method: the main nut is tightened; trimming and polishing sealing surface.

;

  phenomenon: leakage of the valve or connection.

;

 

reason: valve pin, valve sealing surface damage, screw loose.

;

 

elimination method: grinding valve needle, valve port or replace the valve, tighten the screws.

   

; phenomenon: mixing abnormal noise.

;

 

: motor magnet absorbing foreign body.

;

 

exclusion method: open the case to clean up the foreign body.

1 and micro reactor .      
micro reactor the desired reaction pressure, reaction kettle material, whether you need to stir. If you do not need to stir can choose hydrothermal synthesis reactor , such as the need for high pressure reaction conditions, must choose to buy stainless steel material or precious metal reaction kettle.
3, the final reaction required temperature.
4, reaction material viscosity and pH. The viscosity of the reaction substance is directly related to the agitator of the reaction vessel. If the viscosity of the reaction substance is high, the stirring torque of the reactor is large, and vice versa. The acidity of the reaction substance has a great relationship with the material of the reactor, and the different materials have different acid and alkali resistance.
5, heating mode. production of the reactor to provide a variety of heating methods, such as electrical heating, heating module, etc.. In the choice of heating mode, should be based on the requirements of the reaction temperature, because the different heating methods can achieve the highest temperature difference.
