Description
Technical field
The invention belongs to the Chemical Reaction Engineering field, relate to that centrifugal discrete, the atomizing of eddy flow, mass transfer, gas mixing, GAS ABSORPTION, material are synthetic, particulate separation degraded and demist technology.
Background technology
The core of waste gas purification and flue gas desulfurization technique is an absorption tower.The absorption efficiency on absorption tower depends on the dispersion degree and the mass transfer reaction speed of thing phase in the tower.The waste gas purification absorption tower disperses off-gas flows and absorbent by orifice plate or filler.Filler or orifice plate have been arranged, the volume on absorption tower, the corresponding increase of weight.Concerning some waste gas that is difficult for absorbing, orifice plate and filler are high not enough to the dispersion degree of waste gas, influence purification efficiency.
Number rotary spraying and drying method is the most economical in the flue gas desulfurization technique, and desulfuration efficiency can reach 80～85%.This method was used for industry by U.S. JOY company and the joint research and development success of Denmark NIRO company in 1978, occupied 10.2% international desulphurization market at present.Even if Jing Ji desulfur technology is used for the coal-fired thermal power station like this, the investment of complete set of equipments also is equivalent to 10% of gross investment.Must be equipped with the reason of deduster and demister before and after its absorption tower that holds at high price, the complicated and high reason of rotor technology content of transmission device is also arranged.
The rotary spraying and drying method in the absorption tower, adopted one at a high speed the rotating disk of 5～75 centimetres of the diameters of rotation will flow to absorbent centrifugal atomization on the card and go out and realize atomizing, carry out mass transfer reaction with flue gas in the tower.Rotary speed is up to 10000～20000 commentaries on classics/per minutes.Desulfuration efficiency is directly proportional with rotary speed.Because the rotating speed height, the rotating disk requirement for dynamic balance is very high, and also be affected service life.Though domestic this desulfur technology of having introduced, crucial rotating disk is dependence on import still.The rotary spraying and drying law technology is in operation, and to exceed theoretical value a lot of for the absorbent of actual consumption, can reach three times more than, increased operating cost greatly.The reason that produces such result is that the absorbent fogging degree is not high enough.This method desulfuration efficiency is the highest only to reach 85%, its reason is except above-mentioned absorbent fogging degree is not high enough, chief reason is that tower inner rim absorbent distribution density was far smaller than the center after absorbent was rotated the atomizing ejaculation, and peripheral absorbent distribution density is too small.Absorbent by centrifugal ejaculation after, more to peripheric movement, the spacing between the mist pearl is big more, the density that droplet disperses is more little, SO
2Few more with the chance of absorbent contact mass transfer, absorption efficiency is low more.
Summary of the invention
The objective of the invention is, propose a kind of new more simple and feasible, requirement for dynamic balance very low, to the discrete mutually degree height of thing, absorbent distribute more evenly, absorption or combined coefficient is higher, separating granular and the discrete absorbing separator of the integrated eddy flow that carries out of demist.
Technical scheme of the present invention is a kind of waste gas absorption cleaning, synthetic discrete absorption and separation tower of eddy flow of material of being used for, it has a cover to be positioned at the transmission device of housing air inlet end, a rotor that is connected with transmission device, the housing middle part is a centrifugal absorption and separation chamber cavity, lower housing portion is the material-falling hopper 13 that is communicated with centrifugal absorption and separation chamber cavity, it is characterized in that
