Description
Technical field
The invention relates to a kind of gas-solid separation equipment, relate in particular to a kind of streaming cyclone separator in parallel of cutting.
Background technology
Cyclone separator (hereinafter to be referred as " cyclone separator ") is a kind of common gas-solid separation equipment, existingly singlely cut streaming cyclone separator 7 ' as shown in Figure 1 and Figure 2, comprise core pipe 71 ', cylindrical shell 72 ', cone 73 ', ash bucket 74 ', dipleg 75 ', rectangle entrance 76 '.When dust-contained airflow a enters cyclone separator 7 ' by rectangle entrance 76 ', air-flow will become circular motion from rectilinear motion.The overwhelming majority of swirling eddy is under screw from cylindrical shell 72 ' along wall, towards cone 73 ', flows, and is commonly referred to outer eddy flow.Dust-contained airflow a drives particle rotation in High Rotation Speed process simultaneously, and because the density of grit is much larger than gas density, grit produces centrifugal force also much larger than gas, and under the effect of centrifugal force, grit is thrown toward wall; Once grit contacts with wall, just lose inertia force and fall along wall by the momentum of entrance velocity and downward gravity, enter ash bucket 74 ', the dust-exhausting port through dipleg 75 ' bottom leaves cyclone separator.The outer eddy flow that rotation declines, when arriving certain position (generally in cone 73 ' part) on the lower side, can be turned back and continue upwards helical flow with same direction of rotation, is commonly referred to inward eddy.Air-flow after purification is discharged cyclone separator through core pipe 71 ', and the grit of a small amount of collection at large is also escaped thus.
The main performance evaluation index of cyclone separator has two, is respectively separative efficiency and pressure drop.Separative efficiency has shown the ability of cyclone separator trapping grit, and pressure drop has reflected the energy that cyclone separator consumes.
The factor that affects cyclone separator performance is a lot, when cyclone separator structure, size are all determined, enters implication speed, entrance concentration, and the operating parameters such as gas temperature all have a significant effect to its performance.In these operating parameters, entrance concentration and gas temperature depend on the working condition of upstream equipment, and fluctuation range generally has strict restriction, and the operating parameter of being convenient to most control is into implication speed.The separative efficiency of cyclone separator first increases with the increase that enters implication speed, then with the increase that enters implication speed, reduces on the contrary, and separative efficiency is " hump " shape with the change curve that enters implication speed, and separative efficiency has maximum; The implication speed that enters that maximum separation efficiency is corresponding is called " the best enters implication speed ".Research shows: for existing cyclone separator, the best enters implication speed and is about 20-24m/s.The pressure drop of cyclone separator is along with entering the increase of implication speed and monotone increasing, and enters implication speed and is approximated to quadratic relationship.When practical operation enters implication speed and surpasses the best and enter implication speed, the separative efficiency of cyclone separator does not rise counter falling, and its pressure drop continues to raise, and should avoid occurring this rough sledding as far as possible.Considering in practical application that cyclone enters implication speed may fluctuate to some extent, so the cyclone separator design load that enters implication speed is conventionally slightly smaller than the best and enters implication speed.
When the treating capacity of dust-contained airflow is larger, if adopt separate unit cyclone separator, the corresponding increase of its physical dimension, processing, install, the difficulty of transportation also increases.In addition, from Performance Evaluating Indexes, the major diameter cyclone separator of geometric similarity is compared with minor diameter rotary separator, and major diameter cyclone separator separative efficiency reduces, pressure drop increases.Therefore the large diameter cyclone separator of separate unit is difficult to meet separative efficiency requirement harsh in commercial Application (reaching 100% as the third level separator of Mist heat recovering in China's catalytic cracking unit requires particle diameter 10 μ m and above grit separative efficiency), Given this, conventionally the cyclone separator of many minor diameters is combined and worked simultaneously, be called multiple cyclone in parallel (being called for short " cyclone separator in parallel ").
When below separate unit cyclone separator is worked alone for simplicity's sake,, be called by " single separator "; Certain cyclone separator in cyclone separator integral body in parallel is called " resolution element ".When the resolution element of composition cyclone separator in parallel is axial-flow type cyclone separator, this parallel connection cyclone separator is called " axial-flow type cyclone separator in parallel "; When forming the resolution element of cyclone separator in parallel, be while cutting streaming cyclone separator, this parallel connection cyclone separator is called " cutting streaming cyclone separator in parallel ".
The structure of above-mentioned two kinds of forms cyclone separator in parallel has a feature, and each resolution element, from same air inlet pipe (chamber) air inlet, to same collection chamber exhaust, and shares a dust discharge chamber.Due to reasons such as resolution element arrangement mode or manufacture, alignment errors, the tolerance of distributing during each resolution element real work is not quite similar, and the tolerance that enters and leave resolution element also may there are differences.When this differing greatly, easily cause producing " channelling back-mixing " in public dust discharge chamber, have a strong impact on the overall performance of cyclone separator in parallel, even make its inefficacy.When existing cyclone separator in parallel is normally worked, its overall separation efficiency is usually less than under same condition separative efficiency when separate unit resolution element works alone.
Research shows, compares with axial-flow type cyclone separator, cuts streaming cyclone separator and has advantages of self uniqueness, and for example, separative efficiency is high, pressure drop is moderate, anti-back-mixing ability is strong etc.Structure and whole arrangement mode that streaming cyclone separator is cut in optimization are important directions that promotes cyclone separator overall performance in parallel.
