Description
Technical field
This utility model relates to single column double circulation desulphurization technology field, is used for collecting top desulphurization circulating particularly to one
The liquid trap of lime stone slurry.
Background technology
At present, China's energy resource structure based on coal, end 2009 the end of the year coal unit account for the 75% of total installation of generating capacity with
On, sulfur content higher in substantial amounts of fire coal and coal necessarily causes a large amount of S02Discharge, has thereby resulted in serious environmental pollution.
In order to adapt to carry out the needs of environmental protection work in the case of power industry fast development, control coal-burning power plant
Pollutant emission, improve China's air quality and control of acid rain and pollute, national environmental protection portion 2003 will issue GB13223-the end of the year
2003 " fossil-fuel power plant atmospheric pollutant emission standards ", three periods of the new standard scores thermal power plant construction project to different times
The Air Pollutant Emission having respectively provided correspondence controls requirement.Existing sulfur removal technology typically uses Gypsum Wet
Flue gas desulfurization technique technology, a stove single column arrangement, arrange or be not provided with GGH.The desulfuration efficiency design load of full flue gas is the lowest
In 95%.Fresh water (FW) system, limestone slurry liquid preparing system, compressed air system, gypsum dehydration system, Waste Water Treatment and
Emptying system is that two set desulfurizers are public.
Along with the growth of China's economy, air environmental pollution problem is day by day serious, acid rain and the gray haze serious harm people
Healthy even jeopardize existence.2013, State Council issued " suggestion about accelerating development energy-conserving and environment-protective industry " (state
Send out (2013) No. 30) and " prevention and control of air pollution action plan " (promulgated by the State Council (2013) 37), state revenue and expenditure is taken out 4.7 trillion yuan and is used
In environmental improvement, and put into effect the severeest environmental protection policy and measure, it is desirable to before 1 day July in 2017, all firepower electrical plant boilers
Flue gas SO2Discharge is by present 400mg/m3Drop to 100mg/m 3, key area (Beijing-Tianjin-Tangshan, the Yangtze River Delta, Pearl River Delta, respectively
One, big city, two wires) it is reduced to 50mg/m3.According to statistics, only thermal power industry, before 2017, just there are 20,000 multiple stage 30 in the whole nation
Ten thousand kilowatts of units are badly in need of deep desulfuration transformation.In sum, a kind of basing oneself upon now is badly in need of for existing Desulphurization for Coal-fired Power Plant device
There is sulfur content high, the coal-fired adaptable high efficiency flue gas desulfurization technology skill of the desulfuration efficiency under FGD desulfurization island process equipment condition
Art.
Single column Two-way Cycle wet fuel gas desulfurizing technology is 20th century of U.S. Research-Cottre Shu (RC) company 60 the earliest
Age exploitation, be applied to since the seventies on the various power stations of the U.S., this technology transfer at the beginning of the eighties give Germany Nore-gram
Er Ci (NOELL-KRC) company, and obtained further development.Up to now, the whole world oneself have the unit of 26000MW to apply
The single column Two-way Cycle flue gas desulfurization technique of Nore.This technique uses limestone as reactant, runs extremely reliable, it is adaptable to combustion
Use sulphur coal unit.The ultimate principle of this technique is: after flue gas enters absorption tower, through bottom cooling prewashing loop (hypomere),
Obtain cooling and pre-gas washing, be then passed through liquid collecting bucket deflector, enter absorption circuit (epimere), absorb most S02.Purify
After flue gas discharge absorption tower through demister.Absorption tower is divided into two loops and by absorption circuit by the liquid trap in the middle part of absorption tower
Serosity collect and send outer pulp liquid pool back to.The oxidation of calcium sulfite is carried out in absorption tower.
At present, single column bicirculating absorption tower desulfurization slurry liquid trap many employings conical hopper form, bottom liquid trap with
Serosity recovery tube is connected back to slurry circulation case mutually.Flue gas passes through the ring section between liquid trap and absorption tower wall in absorption tower
Entering uptake zone, top, the absorption tower wall on the top of liquid trap has a contraction section constraint loop slurry major part to be pooled to serosity
Liquid trap avoids loop slurry to be directly sprayed to purification cooling zone, bottom, improves the utilization rate of loop slurry.But due to flue gas only
It is to enter uptake zone by annular space between absorption tower wall and liquid trap, causes flue gas to pass through the flow velocity in annular space cross section too high, cigarette
Gas velocity skewness, excessive to the loop slurry impact flow-disturbing of spray, affect serosity and the absorption of sulfur dioxide in flue gas is imitated
Rate, serosity is even carried under one's arms to demister by too high gas speed.It is therefore desirable to the slurry to single column Two-way Cycle fume desulfurating absorption tower
Liquid liquid trap improves, and improves smoke distribution situation, suitably expands flue gas area of passage, it is to avoid serosity is carried under one's arms work by flue gas
With, improve the desulfuration efficiency of single column Two-way Cycle flue gas desulfurization technique.
Utility model content
This utility model purpose is to provide a kind of for inside, the absorption tower of single column Two-way Cycle flue gas desulfurization technique serosity
Liquid trap, overcome in prior art bore bucket shape liquid trap exist flue gas area of passage little, pressure drop is big, velocity flow profile is uneven, office
The problem that portion's flow velocity is too high, and the serosity thereby resulted in is carried under one's arms, back-mixing and the low problem of desulfuration efficiency.
For realizing above-mentioned technical purpose, this utility model multilamellar dish liquid trap replaces original cone bucket shape liquid trap, tool

The flow velocity of lime stone serosity is generally 1.5m/s～2.5m/s, it is contemplated that in actual moving process, in pipe, serosity partly-filled pipe-flow moves, if
Timing can suitably should be amplified with half full packages or lower joint areal calculation, the determination for caliber.
The multilamellar dish-style liquid trap that this utility model relates to is arranged at the pars intermedia of single column Two-way Cycle fume desulfurating absorption tower
Point, replace original cone bucket shape liquid trap, its material many employings carbon steel line with rubber or fiberglass, it is also possible to be that other are at anticorrosion
The metal material of reason.Fig. 5 is the cone bucket shape liquid trap 11 flue gas flow direction schematic diagram in absorption tower in prior art；Fig. 6 is this
The multilamellar dish liquid trap 12 that utility model relates to flue gas flow direction schematic diagram in absorption tower, in figure, the black in liquid trap is real
Heart arrow represents flue gas flow path from bottom to top.From bottom, absorption tower, the flue gas through preliminary spray cleaning is new by this practicality
Type multilamellar dish liquid trap enters the top on absorption tower, and in flue gas uphill process, the lime stone slurry with spray occurs to absorb instead
Should reach to remove the purpose of sulfur dioxide in flue gas.Compared with original cone bucket shape liquid trap 11, the entrance section of flue gas is long-pending to be increased
Greatly, flue gas flow rate distribution more uniform, system dynamic energy consumption reduces, and crosses the flow velocity of stream flue gas and reduces and carry under one's arms lime stone slurry
Effect reduces, and improves desulfuration efficiency.When using the multilamellar dish liquid trap 12 that this utility model relates to, Calx collected by liquid trap
