An overflow weir is arranged at the top of the washing tower. A dynamic balance exchange weir for flue gas and washing liquor is arranged on the lower part of the overflow weir. The present invention has the advantages of scientific concept, reasonable and compact structure, convenient operation, safety, reliability, low energy consumption, low investment, low unit consumption, and high dust removal and desulfurization efficiencies.
Description
One, technical field
The present invention relates to a kind of industrial gas purifying/treating apparatus that is used for, be specially adapted to the dust-removal and desulfurizing of smelting acid making gas cleaning and coal-fired flue-gas, belong to chemical industry, environment protection equipment manufacturing technology field.
Two, background technology
Flue gas desulfurization product and technological development the earliest and the most fruitful be the U.S., secondly be Japan, every Western Europe country.The method of flue gas desulfurization is varied, has reached hundreds ofly, but can be divided into wet method, semidry method and dry method three major types by technological process.The former is most widely used in the world at present, technology is the most ripe.China's exhuast gas desulfurization technology is just studied in sulfuric acid industry and colored metallurgical industrial as far back as the fifties, to the low concentration SO of burning generation
2Processing research the seventies of flue gas just begins.Departments such as China's electric power, metallurgy, chemical industry once researched and developed with regard to flue gas desulfurization technique, through " the Seventh Five-Year Plan ", " eight or five ", " 95 " tackling key problem, the several types that has flue gas desulfurization technique in the world now has been carried out development test, and wherein comparatively typical research and development achievement has: rotary spraying and drying method (SDA method), phospho-ammonium fertilizer method (PAFP method), electron beam irradiation method (EBA method), impulse electric corona plasma method (PPCP method), ACFP (ACF method) etc.But up to the present, China does not still have ripe flue gas desulfurization technique, and above-mentioned listed all kinds of flue gas desulfurization technique also only is in the technological development stage, also fails to obtain obvious effects.
Three, summary of the invention
In view of the problem of above-mentioned existence, the purpose of this invention is to provide a kind of be used for chemical industry, electric power and coloured industry, and can effectively carry out the turbulent_washing type gas treatment equipment of smelting acid making gas cleaning and coal-fired flue-gas dust-removing and desulfurization.
For achieving the above object, the present invention has taked following technical measures:
The present invention is according to the law of conservation of momentum, utilization gas law, Hydrodynamics Theory, the Momentum Transfer process that is taken place in the medium of movement is studied, and control volume is carried out the aggregated momentum EQUILIBRIUM CALCULATION FOR PROCESS, and then designed the turbulent_washing type gas treatment equipment in conjunction with gas, liquid flow type and momentum conservation equation.
Turbulent_washing type gas treatment equipment of the present invention is the tubular pyramidal structure, and it mainly comprises parts such as changeover portion, downflow weir, scrubbing tower, bellows, washing nozzle, accident shower nozzle, collecting tank, demister.Contact for the desire smoke treatment is dashed with cleaning solution rapids in the scrubbing tower cylindrical shell, in the scrubbing tower cylindrical shell, set up dynamic equilibrium " exchange field ", efficiently to carry out the quality transmission.Simultaneously, designed special shower nozzle.This shower nozzle is by spinning momentum hole, momentum adjustment hole, momentum regulating tank, and parameter such as shower nozzle bore, passageway swing angle, passageway bore, inner chamber tapering is set and is improved systematic function, make cleaning solution higher specific surface area be arranged, reach strong turbulent flow type and have very fast liquid surface updating ability, make shower nozzle reach best jeting effect and service life by the shower nozzle ejection.In addition, on the device overall construction design, burn into fouling and wear problem for effective solution equipment, adopt different structural designs and adopt different anti-corrosion materials, the mode that different anticorrosion process combines to solve, that is: the operating mode with high temperature, deep-etching condition harshness concentrates in the zonule on the tubular tower scrubbing tower top that geometry is simple, volume is less, and it is anticorrosion to adopt tight lining teflon material to carry out emphasis.Adopt the superior carbon steel of combination property tightly to serve as a contrast polyolefine material at the bigger parts such as collecting tank of scrubbing tower downstream volume.
Through the present invention after the above-mentioned design compared with prior art, have the following advantages:
1, design science, rational in infrastructure, compact, easy to operate, safe and reliable.
2, dedusting, desulfuration efficiency height.Dust removal efficiency reaches 95%-99%, and desulfurization degree reaches 75%-95%, is much higher than dedusting, the desulfurized effect of domestic like product.
3, energy consumption is low, reduced investment, and the efficient height, unit consumption is low, removes SO
2Per kilogram only costs 0.2-1.00 unit (desulfurization degree reaches 75%-95%), is significantly less than the level of 1.40 yuan/kg of domestic unit consumption.
