CYCLONE SEPARATOR

Cyclone separators or simply cyclones are separation devices (dry scrubbers) that use the principle of inertia to remove particulate matter from flue gases. Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter.

USES OF CYCLONE SEPARATOR

Cyclone separators utilize gravity and a vortex to remove particulates from gaseous streams. Industrial cyclones are used in pollution control applications most commonly as a first stage, lower cost method for removing larger particulate matter (PM) from effluent gas streams.

BUCKLING ANALYSIS

Linear-buckling analysis is also called eigenvalue buckling or Euler buckling analysis because it predicts the theoretical buckling strength of an elastic structure. Eigenvalues are values of load at which buckling takes place. Eigenvectors are buckling shapes associated with the corresponding eigenvalues.

FACTOR OF SAFETY

The definition of the safety factor is simple. It is defined as the ratio between the strength of the material and the maximum stress in the part. ... When the stress in the model remains much inferior to the strength of the material, the safety factor stays superior to 1 and the model is « safe »

BUCKLING FACTOR OF SAFETY

The buckling load factor is an indicator of the factor of safety against buckling or the ratio of the buckling loads to the currently applied loads. Since buckling often leads to bad or even catastrophic results, you should utilize a high factor of safety (at least >3) for buckling loads.

MODEL OF CYCLONE SEPARATOR

SIMULATED MODEL AFTER ANALYSIS WITH STIFFNER

SIMULATED MODEL AFTER ANALYSIS WITHOUT STIFFNER

BUCKLING FACTOR OF SAFETY WITH STIFFNER

The buckling factor should be more.Thus, it is incresed with stiffner to 27.937

BUCKLING FACTOR OF SAFETY WITHOUT STIFFNER

This shows that buckling factor of safety is less without stiffner.

DESIGN STUDY PROCEDURE:

FROM THE BASIC PROCEDURE WE CAN SEE THE SIMULATION RESULTS. IN THIS I HAVE USED 17 SCENARIOS OUT OF THAT ONLY 4 TO 5 BECOMES OPTIMUM.

RESULTS TABLE VIEW:

With this, we can see that green plots shows the optimum results and others with red fails to meet our desired requirements.

Conclusion

Therefore from the results we can see that the optimization of analysis reaches with our desired scenario at 1000mm and also with the parameter of width value of 65mm to 75mm respectively.

By this result we can see the results showing red value for those which fails to meet our criteria or exceeds our limit.

Buckling factor of safety should always be greater than 10.

By using stiffner we can increase the factor of safety value.
