Application and maintenance of

stainless steel reactor



stainless steel reactor information equipment mainly consists of three parts: the tank, jacket, mixing system.
1, contact material and material of stainless steel reactor adopts 304 or 316L stainless steel in accordance with GMP standard.
– parts of stainless steel reactor with stirring form multi frame mixing, to ensure that the material in a short period of time even harmonic; at the same time can be selected, frame type, slurry type anchored
A, stainless steel reactor before driving
2, check the water, electricity and gas meets the safety requirements. The first mixer reactor should be
2, open the steam valve, first open the valve, open the inlet valve. Open the steam valve should be slow, so that the jacket preheating, step by step, the pressure is not allowed to exceed the specified value.
3, the steam valve and the cooling valve can not start at the same time, steam pipeline gas no hammer and collision.
4, open cooling water valve, first open after the opening of the inlet valve return valve. Cooling water pressure shall not be less than 0.1 MPa, is not allowed to be higher than 0.2 mpa.
5, water ring vacuum pump, to open the pump water, when the pump stops, the first stop after pump water, and should be excluded in water pump.
6, check the reactor operation, abnormal should be shut down for maintenance.
7, reactor cleaning, or the use of alkaline brush reactor, be careful not to damage the kettle.
2, the demolition must cut off the mixer power, suspension of warning signs, and.

reactor mixer a good selection method is best to have two conditions, one is the choice of reasonable results, one is simple and convenient, and these two points are often difficult to have at the same time. Because the viscosity of the liquid has a great influence on the mixing state, it is a basic method to select the size of the viscosity of the mixing medium. The mixer of several typical reactors have different range of use with the viscosity. With the increased viscosity of various stirrer use in order to push type, turbine type, slurry type, screw type and anchored here, to push forward smaller share of large capacity liquid with low speed, small volume of liquid with high speed


commonly used operating conditions:  
;   frame type  



is suitable for high viscosity fluid mixing, heat transfer, reaction and other operation process; characteristics: low shear, high cycle ability, super low speed operation, high energy consumption; stirring speed 60~120r/min.

is divided into elliptic bottom, 90 degrees, 120 degrees tapered cone bottom, anchored, glass lined special anchor structure.


common operation conditions: n=100 ~ 500rpm, v=3 ~ 15m/s 
by baffles or guide cylinder, axial cyclic


typical axial flow impeller, suitable for low viscosity fluid mixing, heat transfer, circulation, solid suspension, dissolution, etc. characteristics: low shear, strong cycle, high speed operation, low energy consumption; stirring speed 200~1500r/min.

is divided into upper and lower inclined structure, if the high-speed operation of the need to bring stability.

(4) valve, pressure gauge, safety valve installation and by tightening the nut, namely, to achieve the effect of sealing, the sealing surface of the arc connecting two no relative rotation of all screw connection parts in the assembly, shall apply lubricant or oil mixed with graphite, so as not to bite dead. The use of the valve: needle valve line seal, just gently turn the valve needle, pressing the sealing surface that can achieve good sealing performance, the prohibition of excessive force, so as not to damage the sealing surface.
