Abstract
A cyclone composite condensated water recovery device utilizing baffles comprises a cyclone barrel. The cyclone barrel is provided with a gas inlet passage, a gas outlet passage and a liquid outlet. Four baffle separators, which are distributed in the shape as a Chinese character 'tian', are mounted above the gas inlet passage, outlets of four baffles are arranged clockwise or anticlockwise, so that flue gas flowing through the baffles can rotate. The baffle separators serving as cyclone blades are combined with the cyclone barrel to form a secondary centrifugal separator. Since the baffles are arranged reasonably, gas flow rotates after flowing through the baffles, the baffles have inertia separation effects while replacing the cyclone blades in cyclone separation, and the inertia separation and the cyclone separation are combined organically so that small fog drops can be separated effectively, condensed water recovery efficiency is increased greatly, while structure is simplified and cost is reduced.
Description
Technical field
The invention belongs to energy-saving and emission-reduction field, relate in a kind of large-scale power station after flue gas desulfurization by the deflection plate whirlwind combined type condensation apparatus for recovering of flue gas condensing recycle-water.
Background technology
Due to northern China water resources shortage, water is the precious resources of irreplaceable inconvenience transport, and the needs that meet development by the existing water yield are unique feasible way.And that desulphurization system water accounts for the ratio of power plant's total water is very high, this just makes the water saving of power plant of China become a urgently open question.
In large-scale wet desulphurization power plant, desulphurization system water has accounted for 50 ~ 70% of full station-service water.In arid area, owing to lacking water source, power plant has to adopt dry desulfurization.And dry desulfurization is compared wet desulphurization, cost will exceed more than 500,000,000 RMB.If can make wet desulfurization system moisturizing decline, part arid area power plant can adopt wet desulphurization, just cost can greatly reduce.
Flue gas after desulfurization is generally the saturated flue gas of 50 DEG C of left and right, the wherein moisture 200t/h that is greater than, and some of water is reclaimed in condensation, can be for wet desulfurization system self moisturizing or as other purposes.
At present mainly contain four kinds for the device of gas-liquid separation: gravity separator, screen separator, deflection plate separator and whizzer.Wherein, gravity separator is mainly used in removing the drop that particle diameter is greater than 150 microns; The particle diameter that screen separator is mainly used in low tolerance is the separation of the drop of 5-7 micron; Deflection plate separator is mainly used in and removes particle diameter is the drop of 10-100 micron; Whizzer can produce the centrifugal force of large 2000 times of force of gravity, can effectively remove the drop that particle diameter is 4-5 micron.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, effective drop in recovered flue gas, reclaim to reach the water that in saturated flue gas, condensation goes out after desulfurization, make few not even deflection plate whirlwind combined type condensation apparatus for recovering of water consumption of water consumption in process of wet desulphurization.
For achieving the above object, the technical solution adopted in the present invention is: comprise the cyclone cylinder with inlet channel, outlet passageway and liquid outlet, in cyclone cylinder, be positioned at inlet channel above deflection plate separator is installed, deflection plate separator is divided into four groups as sphere of movements for the elephants lattice, four groups of deflection plate outlet entirety are by arranging clockwise or counterclockwise, the flue gas passing through is rotated, and described deflection plate separator is combined into second level whizzer as swirl vane and cyclone cylinder simultaneously.
Described inlet channel stretches into cyclone cylinder inside, makes cyclone cylinder bottom form aqua storage tank, and liquid outlet is opened in the aqua storage tank of cyclone cylinder bottom.
Described inlet channel flow area is square or approaches square.
Described outlet passageway stretches into cyclone cylinder inside, and outlet passageway cross section is rectangle or circle.
Thereby the present invention adopts deflection plate composition stream plate, separator has replaced the swirl vane in whizzer, deflection plate separator is combined into second level whizzer as swirl vane and cyclone cylinder simultaneously, gas after separation leaves from outlet passageway, and liquid flows out by the liquid outlet of cyclone cylinder bottom.Two kinds of separators are organically combined, both improved the efficiency that condensed water reclaims, do not make again structure complicated.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the overall structure schematic diagram of deflection plate separator of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Referring to Fig. 1, the present invention includes with inlet channel 1, the cyclone cylinder 3 of outlet passageway 4 and liquid outlet 5, inlet channel 1 flow area is square or approaches square, inlet channel 1 stretches into cyclone cylinder 3 inside, make cyclone cylinder 3 bottoms form aqua storage tank, liquid outlet 5 is opened in the aqua storage tank of cyclone cylinder 3 bottoms, outlet passageway 4 stretches into cyclone cylinder 3 inside, and outlet passageway 4 cross sections are rectangle or circle, in cyclone cylinder 3, be positioned at inlet channel 1 above deflection plate separator 2 is installed, deflection plate separator 2 is divided into four groups as sphere of movements for the elephants lattice, four groups of deflection plate outlet entirety are by arranging clockwise or counterclockwise, the flue gas passing through is rotated, described deflection plate separator 2 is combined into second level whizzer as swirl vane and cyclone cylinder 3 simultaneously.This deflection plate separator 2, simultaneously as swirl vane, is combined into second level whizzer with cyclone cylinder 3, and the gas after separation leaves from outlet passageway 4, and liquid flows out by the liquid outlet 5 of cyclone cylinder bottom.
The invention has the advantages that:
Utilize the deflection plate separator of deflection plate composition to replace the swirl vane in whizzer, thereby two kinds of separators are organically combined, both improved the efficiency that condensed water reclaims, do not make again structure complicated.The present invention is mainly used in north cold area large thermal power plant, and main purpose is by the water that after recovery desulfurization, saturated flue gas condensation goes out, thereby realizes the few not even water consumption of water consumption of wet desulphurization.
