Description
Technical field
The present invention relates to a kind of cyclone separator of adjustable separating effect, particularly a kind of Novel cyclone separating device that regulates its separating effect by changing cyclone separator internal structure, belongs to the technical field of circulating fluidized bed boiler device.
Technical background
Cyclone separator is a kind of separator, and it,, by the flow rotation motion of vertical cylinder structure, removes the solid particle in conveying gas body medium, to reach gas solid separation object, belongs to a key component in CFBB.In CFBB, main operation principle is: the high-temperature material in boiler after burning and flue gas, by the import of cyclone separator, enter cyclone separator, by the centrifugation of cyclone separator, a large amount of high-temperature materials are separated from flue gas.Send again combustion chamber back to, thereby keep material and the desulfurizing agent can recycled for multiple times, to reach the order of high burning efficiency and high desulfurization efficiency, however most important as the performance quality of the cyclone separator of one of key equipment.In existing recirculating fluidized bed, for the variable working condition situation of boiler, the current structure of cyclone separator can not meet the demands.The one,, in the variation due to coal in service of boiler, cause the operational factor of boiler to change a lot, do not reach boiler parameter design load, but the separative efficiency of cyclone separator is constant, thus cause the burning of boiler and the internal circulating load of material inconsistent, make boiler heating surface caloric receptivity uneven, cause boiler efficiency to decline, economic loss is serious; The 2nd,, when the Coal-fired capacity of recirculating fluidized bed strengthens, the internal circulating load regulating power variation of cyclone separator to high-temperature material, is that the cyclone separator of currently available technology cannot meet.The 3rd,, from air outlet flue gas out, more or less carry partial material secretly and entering into next stage operation, do not reach desirable separating effect.
The present invention is exactly the deficiency that will overcome existing cyclone separator, the Novel cyclone separating device that provides a kind of internal structure to change to some extent.This Novel cyclone separating device can solve in boiler operatiopn in variable working condition situation, the inconsistent problem of the internal circulating load of quantity combusted and cyclone separator, and separate the problem of gas-solid two-phase weak effect.By this kind of structural change, reach adjusting function good, gas-solid separating effect is good, operates more stable advantage.
Summary of the invention
The technical issues that need to address of the present invention are: the cyclone separator that a kind of new internal structure is provided, this cyclone separator is by installing baffle plate and screen cloth, by from controlling mass flow and improving the improvement to some extent of separating effect two aspects, thereby improve the return flow of recycle stock in boiler, make up the each heating surface of the boiler unbalanced shortcoming that recepts the caloric, improve the utilization ratio of boiler, improve separative efficiency and the gas-solid separating effect of cyclone separator simultaneously, also can improve the efficiency of whole recirculating fluidized bed, reduce costs, reduce the waste of fuel energy.
In order to address the above problem, the present invention is achieved through technology,
A kind of efficiency Cyclone, it adopts vertical cylinder structure, comprises air inlet, baffle plate, circular cylinder body, conical shell, air outlet, discharging opening and screen cloth.Air inlet adopts the first passage of straight-through rear screw, is welded on the top of circular cylinder body; Baffle plate is arranged on respectively circumferential, the axial wall of air inlet and circular cylinder body, and baffle plate all adopts axle to be connected with wall; Circular cylinder body and conical shell are integrally welded, and circular cylinder body is upper, conical shell under; Air outlet is drum forms, is positioned at circular cylinder body top center, is connected with Type of Welding with cylindrical shell end socket; Discharging opening is connected with Type of Welding with the lower end of conical shell; Screen cloth is connected with air outlet, is connected with screw-type with air outlet cylindrical shell.Flue gas with high-temperature material enters after cyclone separator by helical form air inlet, the existing water conservancy diversion of baffle plate of air inlet has again the effect of controlling air flow rate, air-flow is subject to cylindrical shell guide effect to produce strong rotation subsequently, along cylindrical shell spirality, enter Whirlwind barrel main part downwards, by regulating the angle of the baffle plate of installing along barrel, for the size of air inlet flow, regulate better the rotate effect of air-flow, the solid material that density is large is like this thrown toward wall under the effect of centrifugal force, and under Action of Gravity Field, along barrel whereabouts device bottom to tornadotron discharging opening, the air-flow of rotation shrinks to center flow in cylindrical shell, upwards forming secondary vortex flow flows out through wireway to air outlet, air outlet place is provided with screen cloth, play the effect of secondary separation.
Baffle plate is positioned on air inlet and barrel, and with connecting axle form, is connected between wall, the opening angle of the stretching controllable register by valve rod in the middle of baffle plate rear portion, and angle is changed to 0 °～30 °.
The baffle plate number of vertically, circumferentially installing at cylinder inner wall should be consistent with cylindrical shell height, and highly higher baffle plate number increases in right amount, highly reduces the also corresponding minimizing of baffle plate number.
The screen cloth of air outlet can be connected with screw with air outlet barrel, can realize easy accessibility.
Screen cloth pore diameter is less than the particle diameter of solid material.
Adopted technique scheme, the invention has the beneficial effects as follows:
With the flue gas of high-temperature material, enter the air inlet of cyclone separator, the opening angle of the stretching controllable register by baffle plate valve rod, control the flow of material, material enters behind the cyclone separation of cylindrical shell, suitably adjust the angle of barrel overhead gage, change the rotate effect of material, thereby adjustment material contacts with wall, and then the separative efficiency of raising flue gas and material, the smoke gas flow of rotation shrinks to center flow in cylindrical shell, upwards form secondary vortex flow and flow out through wireway to air outlet, air outlet place is provided with screen cloth, plays the effect of secondary separation.Through control and the filtration of outlet screen cloth to flue gas of mass flow, make gas solid separation efficiency higher, gas-solid separating effect is more obvious.
Therefore, the present invention, compared with existing cyclone separator, has outstanding advantage and is: (1) solves boiler combustion amount and the inconsistent shortcoming of cyclone separator internal circulating load by the adjusting of baffle angle, and adjusting function is better, thereby improved separative efficiency, reduced running cost; (2) the simple screen cloth of air outlet place mounting structure, improves separating effect again, saves meticulous separation costs; (3) workable, adjusting function, simple in structure, easily manufactured.
A kind of efficiency Cyclone provided by the invention, variation structurally, has realized the adjustability in operation operating mode, for practical application provides great convenience, can be widely used in the industrial operations such as boiler recirculating fluidized bed, gas solid separation.
