Abstract
The utility model relates to a spiral diversion type cyclone separator which includes an outer cylinder (1), wherein the lower part of the outer cylinder (1) is connected with a reverse cone (3) and an inner cylinder (7) arranged in the outer cylinder. A spiral fin (2) are arranged on the outer side surface of the inner cylinder (7), a spiral diversion trench is formed between the spiral fin (2), the outer cylinder (1) and the inner cylinder (7). An inlet of the spiral diversion trench is communicated with the feed inlet (8) at the top of the outer cylinder (1), a back mixing prevention member (5), the periphery of which is round, is arranged at the lower part of the inner cylinder (7). The utility model has simple structure, high separation efficiency, good separation effect and is easy to assemble, and is not only can be applied for the gas-solid separation but also can be applied for the separation of non-homogeneous phase gas-liquid, liquid-liquid and liquid-solid which have certain density differences and are immiscible with each other.
Description
Technical field
The utility model relates to industrial feed separation equipment, particularly a kind of spiral stream guidance formula cyclone separator that is used to separate the heterogeneous material with density contrast.
Background technology
Cyclone separator is widely used in industries such as chemical industry, metallurgy, pharmacy, environmental protection, and its utilization has the centrifugal force that the gas-solid phase materials rotation of certain flow rate the time is produced, and solid particle is separated from material, reaches the purpose of gas solid separation.The cyclone separator kind is many, the CLT type is arranged, the D type, Type B, JC type and bypass type, diffusion type, long cone type, multitube, tornado, twin-stage vortex etc., their basic structure all by the lower end be connected with downward contraction cone outer cylinder body and place the inner barrel in the outer cylinder body to form, form annular cavity between outer cylinder body and the inner barrel, there is charging aperture the upper end of outer cylinder body, there is the solid particle discharging opening after the separation cone lower end, gas discharge outlet after the separation is arranged on the inner barrel, because effectively rotating cycle is fewer in above-mentioned annular cavity for material, be prone to " short circuit " phenomenon of Flow of Goods and Materials, solid particle does not also come out just to be carried by gas to enter the inner barrel discharge from feed separation well; In addition, because the effect of inertia of material rotation can produce eddy current at the cone top of outer cylinder body lower end, the solid particle after separating is rolled again, brought into inner barrel and discharge through gas discharge outlet, cause separative efficiency lower, effect is not satisfactory.
In order to improve above-mentioned situation, people have taked many measures, when not reaching the separating effect of expection at rotating cycle is fewer, generally the method for Cai Yonging is that two even three cyclone separators are together in series, though separative efficiency is improved, has caused complex structure, a series of problems such as maintenance trouble, pressure drop increase have been installed; And preventing to produce aspect the eddy current problem, adopt special constructions such as long cone, diffusing cone, radiation shield, though can effectively prevent back-mixing, because of complex structure, make that trouble, cost are too high to be influenced it and apply.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved spiral stream guidance formula cyclone separator is provided, and effective rotating cycle of material rationally is set, and prevents the eddy current back-mixing, improves separative efficiency.
The purpose of this utility model can realize by following technical measures: this separator comprises that the lower end is connected with the outer cylinder body and the inner barrel that places in the outer cylinder body of the cone of downward contraction, form annular cavity between outer cylinder body and the inner barrel, there is charging aperture the upper end of outer cylinder body, the charging aperture cut-grafting is communicated with outer cylinder body, there is the solid particle discharging opening cone lower end, the divided gas flow outlet is arranged on the inner barrel, the lateral surface of inner barrel is provided with helical wing plate, spacing between the helical wing plate is corresponding with the charging aperture height, its external diameter is littler than the internal diameter of outer cylinder body, between helical wing plate outer side edges and the outer cylinder body certain interval is arranged, helical wing plate is at outer cylinder body, form the spiral stream guidance groove between the inner barrel, the inlet of spiral stream guidance groove is connected the charging aperture of outer cylinder body upper end, correspondence position is provided with anti-back-mixing member below the inner barrel lower end, anti-back-mixing member can be suspended under the inner barrel or be fixed on outer cylinder body and the cone junction, and its size is suitable with the inner barrel external diameter.
The charging aperture of material through the outer cylinder body upper end with certain flow rate enters the spiral stream guidance groove, in the repeatedly centrifugation of spiral stream guidance groove back warp, solid particle is subjected to centrifugal action, being thrown toward the outer cylinder body inwall falls to cone cavity and discharges through the solid particle discharging opening, gas is then walked downwards along the spiral stream guidance groove, gas discharge outlet through inner barrel is discharged, because effect of inertia, near cone and outer cylinder body intersection, can produce vortex phenomenon, solid particle after anti-back-mixing member then can prevent to separate is rolled again, thereby has improved separative efficiency.
The utility model forms the spiral stream guidance groove with certain rotating cycle owing to be provided with helical wing plate between inside and outside cylindrical shell, has avoided " short circuit " phenomenon of gas-solid phase materials rotational flow; The solid particle that is provided with below inner barrel after anti-back-mixing member can be avoided separating is rolled again, has the effect that prevents because of the eddy current back-mixing, it is simple in structure, make and install easily, the separative efficiency height, satisfactory for result, not only be applicable to the separation of gas-solid phase, also can be used for having immiscible gas-liquid, liquid liquid of certain density contrast, the separation of heterogeneous material such as liquid-solid.
