Abstract
The vortex separator to separate solid particle in high-temperature gas features that it consists of several parallelly connected vortex separating units, which are fixed horizontally inside a vertical high temperature-resisting metal frame with the dust-dropping passage being arranged between separating units. Adopting parallelly connected high-temperature vortex separating units results in higher separation efficiency than inertial separator and large-aperture vortex separator. Setting the dust exhaust at the lower part of side wall of gas-solid separation chamber and cleaning with jet blast can prevent effectively dust deposition, adhesion and coking, and makes it be possible to treat dusty airflow with temperature as high as 600-1000 deg.C.
Description
The present invention relates to be used for the high-temperature separator that dry type is removed the fine-particle solid that is blended in air-flow, particularly relate to the separator that is used as in a kind of new type high temperature dust arrester; Separator as a kind of CFBB use.
The various dry type separators that utilize the air-flow rotation that fine-particle solid is separated at present, be broadly divided into inertia type and whirlwind type two classes, their dust separation efficient depends on following three factors: (1) separation (W2/rg): promptly little solid particle is the ratio of suffered centrifugal force and gravity in rotation.Separation is big, the separative efficiency height of dust; (2) anglec of rotation of air-flow: big more dust is easy more is separated for it; (3) airborne dust rate: after promptly dust was rotated flow separation and goes out main gas, because of carrying the ratio of Dust Capacity in the amount of reasons such as bounce-back, flow perturbation rollback again in the air-flow and the initial air-flow, obviously this value was big more again, and separative efficiency is low more.
The inertia type separator is to utilize gas to turn fine-particle solid is separated from air-flow.But all these class separators at present, because reentrainment of dust is big, the air-flow turning speed that design is selected for use can only be lower, angle of turn is also smaller, is generally about 90 °, so that they all have a volume is big, shortcoming such as separative efficiency is low.
Whirlwind type separator is that air-flow is tangentially imported in the cylinder, makes it produce strong rotation and separates dust efficiently.Because its air-flow anglec of rotation can be up to a few, reentrainment of dust is little, so the separative efficiency height is widely used.It can be divided into monotubular formula and two kinds of patterns of multitube, when handling big volume airflow, because of multibarrel drum diameter only is 0.1～0.3 meter, 0.5～9 meter of drum diameter than monotubular formula is much smaller, basic identical at resistance, be under the condition of flow velocity basically identical, multibarrel separation will exceed several times even tens times, so the separative efficiency height of multiclone.For example: in CFBB, though denumerable of monotubular formula cyclone separator be arranged in parallel, single its barrel diameter still reached 3～8 meters obviously this moment separative efficiency than low many of the multiclone of minor diameter.
Multiclone has two kinds of reverse-flow type and single flow.Reverse-flow type is that the gas feed flow direction is opposite with the outlet flow direction, and each whirly tube adopts and vertically is arranged in parallel, and dust is discharged from the bottom of cylinder.Single flow is that the airflow inlet flow velocity is identical with exit velocity, and generally employing level of each whirly tube is arranged in parallel, and dust is discharged from the end of cylinder.The reverse-flow type multi-tube dust cleaner can only be arranged vertically, the airflow inlet complex structure, and inside is difficult for being provided with the water-cooled stay pipe.Though the single flow gas inlet and outlet is simple in structure, in horizontally disposed whirly tube, ash discharge is not smooth, under hot conditions, and easily knot ash, coking.So at present they all can only in, use under low temperature (＜500 ℃) condition.
The objective of the invention is to overcome the prior art shortcoming, provide a kind of and have high separating efficiency under hot conditions, compact conformation, amplification are good, dependable performance and high temperature vortex separator applied widely.
The present invention is achieved in that whole separator is to be composed in parallel by the vortex separator unit, and the vortex separator unit horizontal is fixed in the vertically arranged resistant to elevated temperatures metal framework, and the grey-way that falls vertically is arranged in respectively to be organized between the horizontal vortex separative element.
The embodiment of the invention is described further in conjunction with the accompanying drawings.

By shown in Figure 5, high temperature vortex separator is composed in parallel by vortex separative element 9, and each cyclonic separation unit horizontal is fixed in the vertically arranged resistant to elevated temperatures metal framework 12, and the grey-way that falls 13 vertically is arranged in respectively to be organized between the cyclonic separation unit.
Shown in Fig. 1,2,3, the cyclonic separation unit revolves chamber 1 by rising of circle and gas-solid separation chamber 6 forms, revolves layout in the chamber 1 and leads the bottom that vane sheet 2 and peripheric jet flow nozzle 5, ash discharging hole 8 are arranged on gas solid separation chamber 6 side wall surfaces rising.7 expression air flow directions in Fig. 1,2,3 is air compartment, 4 is air inlet, and cyclonic separation unit principle can be as seen from the figure, when the dust air-flow revolves chamber 1 through circular, leading the vane sheet and tangentially penetrating under the effect of nozzle 5, strong vortex flow is given birth in the dust miscarriage, and dust is split into the wall of circular gas solid separation chamber 6, under the drive of swirling eddy,, discharge by being arranged on the basifacial ash discharging hole 8 of gas solid separation chamber cylinder sidewall at last to front slide along its wall spirality.
Ash discharging hole 8 length L of gas solid separation chamber 6 are 0.5～1.5 with working the ratio that revolves chamber diameter D in the cyclonic separation unit, and the ash discharging hole width B is 0.1～0.4 with working the ratio that revolves chamber diameter D.The cyclonic separation unit can be by refractory ceramics or heat resisting cast steel manufacturing.
The high temperature vortex separator concrete structure is by shown in Fig. 4,5,6,10 is air flow direction among the figure, 11 are the grey tube connector that falls, and 14 is jet wind air channel, 15 jet wind inlets, 16 are the dust outlet, its operation principle is described below, and the dust air-flow directly passes high temperature vortex separator, and jet wind enters the air compartment 3 of each cyclonic separation unit by jet wind air channel 14 from 15 imports, from 5 ejections of peripheric jet flow nozzle, play a part cleaning circular gas solid separation chamber and strengthen swirling eddy.During greater than 800 ℃, separate easily bonding and coking soot particle in flue-gas temperature, can open jet wind, prevent grey bonding so effectively, should adopt high-temperature sealing material to seal up and down between the cyclonic separation unit, prevent that jet wind from entering grey-way.
Refractory metal framework 12 can be to be made with the steel plate welding by heat-resisting steel sheet and plate or water pipe, but water flowing in the water pipe, vapour or steam water interface get up with the interconnection that installs.
The present invention compared with prior art owing to adopt the parallel connection of high temperature vortex separative element, so compare inertia The separative efficiency height of separator and major diameter cyclone separator is in addition because ash discharging hole is arranged on gas solid separation chamber side The bottom of wall, and adopt the cleaning of jet wind, thus can effectively prevent deposition, bonding and the coking of soot particle, Can treatment temperature up to 600 ℃～1000 ℃ dust air-flow, this is that present various multitube separator is not accomplished .
