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 the energy-saving and emission-reduction field, relate to the deflection plate whirlwind combined type condensation apparatus for recovering that passes through the flue gas condensing recycle-water in a kind of large-scale power station after the flue gas desulfurization.
Background technology
Because northern China water resources shortage, water are the precious resources of irreplaceable inconvenience transportation, the needs that satisfy development with the existing water yield are unique feasible way.And that the desulphurization system water accounts for the ratio of power plant's total water is very high, and this just makes the water saving of China power plant become a urgently open question.
In the large-scale wet desulphurization power plant, the desulphurization system water has accounted for 50 ~ 70% of full station-service water.In the arid area, owing to lack the water source, power plant has to adopt dry desulfurization.And dry desulfurization is compared wet desulphurization, and cost will exceed more than 500,000,000 RMB.If the wet desulfurization system moisturizing is descended, then part arid area power plant can adopt wet desulphurization, and cost just can greatly reduce.
Flue gas after desulfurization is generally the saturated flue gas about 50 ℃, and is wherein moisture greater than 200t/h, and the some of water of condensing and recycling then can be used for wet desulfurization system self moisturizing or be used as other purposes.
The device that is used for gas-liquid separation at present mainly contains four kinds: gravity separator, screen separator, deflection plate separator and whizzer.Wherein, gravity separator is mainly used in and removes particle diameter greater than 150 microns drop; The particle diameter that screen separator is mainly used in low tolerance is the separation of the drop of 5-7 micron; The deflection plate separator is mainly used in and removes particle diameter is the drop of 10-100 micron; Whizzer can produce the big 2000 times centrifugal force of force of gravity, can effectively remove the drop that particle diameter is the 4-5 micron.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, can effectively reclaim the drop in the flue gas; Reclaim the water that condensation goes out in the saturated flue gas after the desulfurization to reach, make in the process of wet desulphurization the not even deflection plate whirlwind combined type condensation apparatus for recovering of water consumption of few water consumption.
For achieving the above object; The technical scheme that the present invention adopted is: comprise the whirlwind tube that has inlet channel, outlet passageway and liquid outlet; In the whirlwind tube, be positioned at inlet channel above the deflection plate separator is installed, deflection plate separator such as sphere of movements for the elephants lattice are divided into four groups, the outlet of four groups of deflection plates is whole by arranging clockwise or counterclockwise; Make the flue gas that passes through rotate, described deflection plate separator is combined into second level whizzer as swirl vane and whirlwind tube simultaneously.
It is inner that described inlet channel stretches into the whirlwind tube, makes the whirlwind tube bottom form aqua storage tank, and liquid outlet is opened in the aqua storage tank of whirlwind tube bottom.
Described inlet channel flow area is square or approaching square.
It is inner that described outlet passageway stretches into the whirlwind tube, and the outlet passageway cross section is rectangle or circle.
Thereby the present invention adopts deflection plate to form stream plate separator has replaced the swirl vane in the whizzer; The deflection plate separator is combined into second level whizzer as swirl vane and whirlwind tube simultaneously; Gas after the separation leaves from outlet passageway, and liquid then flows out through the liquid outlet of whirlwind tube bottom.Two kinds of separators are organically combined, both improved the efficient that condensed water reclaims, do not make structure complicated again.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention;
Fig. 2 is the overall structure sketch map of deflection plate separator of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Referring to Fig. 1, the present invention includes the whirlwind tube 3 that has inlet channel 1, outlet passageway 4 and liquid outlet 5, inlet channel 1 flow area is square or approaching square; Inlet channel 1 stretches into whirlwind tube 3 inside; Make whirlwind tube 3 bottoms form aqua storage tank, liquid outlet 5 is opened in the aqua storage tank of whirlwind tube 3 bottoms, and outlet passageway 4 stretches into whirlwind tube 3 inside; And outlet passageway 4 cross sections are rectangle or circle; In whirlwind tube 3, be positioned at inlet channel 1 above deflection plate separator 2 is installed, deflection plate separator 2 is divided into four groups like the sphere of movements for the elephants lattice, the outlet of four groups of deflection plates is whole by arranging clockwise or counterclockwise; Make the flue gas that passes through rotate, described deflection plate separator 2 is combined into second level whizzer as swirl vane and whirlwind tube 3 simultaneously.This deflection plate separator 2 is combined into second level whizzer simultaneously as swirl vane with whirlwind tube 3, and the gas after the separation leaves from outlet passageway 4, and liquid then flows out through the liquid outlet 5 of whirlwind tube bottom.
The invention has the advantages that:
The deflection plate separator that utilizes deflection plate to form replaces the swirl vane in the whizzer, thereby two kinds of separators are organically combined, and has both improved the efficient that condensed water reclaims, and does not make structure complicated again.The present invention is mainly used in the north cold area large thermal power plant, and main purpose is through reclaiming the water that the saturated flue gas condensation goes out after the desulfurization, thereby realizes not even water consumption of the few water consumption of wet desulphurization.
