In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 looks perspective view for the master of the cyclone that the utility model embodiment provides;
The plan structure schematic diagram of the upper body that Fig. 2 provides for the utility model embodiment, lower case and disturbance post.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of the utility model protection.
As Fig. 1-Fig. 2, the utility model embodiment provides a kind of cyclone removed for wet desulfurization system flue gas drop, and described wet desulfurization system comprises desulfurizing tower and chimney, and described desulfurizing tower comprises demister.Described cyclone comprises upper body 1, lower case 3 and multiple swirl vane 4, is connected bottom described lower case 3 with the outlet of described demister, and described upper body 1 top is connected with described chimney.Swirl vane 4 is located in lower case 3, and swirl vane 4 is spirality, and described multiple swirl vane 4 is dish ladder arrangement in described lower case 3; Preferably, described multiple swirl vane 4 coils the lift angle of ladder arrangement is 45 °.Wherein, described upper body 1 and described lower case 3 can be cylindrical or other shapes, as rectangular structure; Preferably adopt cylindrical, be convenient to the rotating turbulence motion of flue gas.The connected mode of cyclone and demister and chimney all adopts the mode of Flange joint, Stability Analysis of Structures and be convenient to installing/dismounting.
As Fig. 1-Fig. 2, described upper body 1 is provided with drainage arrangement, and described drainage arrangement comprises osculum and water leg, and osculum is opened in described upper body 1, and described osculum is connected with drainpipe 2.This osculum is flange hole, and this drainpipe 2 is provided with the adpting flange suitable with described osculum, and namely the connected mode of osculum and drainpipe 2 is Flange joint.Preferably, described drainpipe 2 is arranged obliquely with described upper body 1 angle at 45 °, is convenient to the discharge of the drop collected.The structure of water leg is: the top of described lower case 3 is flush-mounted within the bottom of described upper body 1, and namely the gap between described upper body 1 and lower case 3 forms water leg, and described osculum is opened on described water leg.In the present embodiment, described osculum is 4, and described 4 osculum uniform ring are located in described upper body 1.
In addition, during actual use, this upper body 1 can be selected to adopt chimney on the spot, and namely this cyclone comprises housing and is located at the multiple swirl vanes 4 in housing, and this housing is flush-mounted within described chimney bottom; Drainage arrangement is arranged on the bottom of chimney.Take this structure, the structure of cyclone can be simplified further, this cyclone is taken up an area less, be convenient to install and use.And, because chimney corrosion resistance is better, the corrosion resistant material making upper body 1 therefore can be saved.
As Fig. 1-Fig. 2, as a kind of preferred structure of the present embodiment, in described cyclone, be provided with flow perturbation device along axis.Preferably, described flow perturbation device comprises disturbance post 5, and described disturbance post 5 is bullet-shaped and conehead end is arranged bottom described lower case 3.The height of this disturbance post 5 is preferably with the height of lower case 3 suitable, conehead bottom portion can with lower case 3 bottom flush with or slightly higher than bottom lower case 3.In addition, this disturbance post 5 can be hollow body, to alleviate the weight of equipment; This disturbance post 5 is fixed in lower case 3 by support, to improve its operation stability.When flue gas enters cyclone, under the effect of disturbance post 5, gentle transition is to the inwall side of lower case 3, thus increases the contact of flue gas and swirl vane 4, effectively improves the removal effect of drop.
The operation principle of this cyclone is principle of inertia, and after desulfurization fume enters cyclone inside with certain speed bottom lower case 3, air-flow produces strong rotating turbulence motion under the effect of winding staircase shape swirl vane 4; Due to varying in size of the power such as the centrifugal force be subject between drop and gas, centripetal buoyancy, fluid drag, in flue gas, most of drop is rotated to upper body 1 inwall wall by swirler blades; Drop and upper body 1 inwall collide and adhere to, and after the drop of trapping collects in water leg, discharge via drainpipe 2, thus reach the object of administering chimney and raining.
Be 2,000,000 Nm for an exhaust gas volumn
3the power plant of/h, adopt limestone-gypsum method to remove sulfur dioxide in flue gas, during the cyclone not adopting the present embodiment to provide, chimney breast drop amount is 68mg/m
3, there is chimney in power-plant flue gas discharge downstream and to rain problem.After desulfurizing tower top increases the cyclone that the present embodiment provides, chimney breast drop amount is less than 30 mg/m
3, power plant's downstream chimney problem of raining effectively is alleviated.
The utility model embodiment has following beneficial effect: by arranging cyclone on desulfurizer mist eliminator top, cyclone spiral blade is in dish ladder arrangement, can make desulfurization fume in cyclone, produce strong rotating turbulence motion, drop in air-flow is brought to and upper body 1 contact internal walls and being removed by air-flow, thus effectively improves the situation that chimney rains.Use this cyclone, the pressure drop of flue gas is less, is generally less than 200-600pa, is beneficial to the fume emission of desulphurization system.This hydrocyclone structure is simple, only needs a little space to arrange, can arrange, therefore applied range at the chimney place in-situ reformation of existing desulphurization system.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
