Abstract
An efficient multi-pipe spiral mist removing and dust removing system comprises an outer shell, a plurality of fixing brackets arranged at intervals in the outer shell in a height direction, a mist removing and dust removing combination formed by a plurality of tubular spiral mist and dust removers, distributed in the outer shell and arranged vertically between two fixing brackets, and a washing system arranged on the fixing brackets. The mist removing and dust removing efficiency of the efficient multi-pipe spiral mist removing and dust removing system is high, and the ultra-clean emission is realized. The efficient multi-pipe spiral mist removing and dust removing system is widely applicable to flue gas purification treatment of a wet flue gas desulfurization system of a coal-fired boiler of a power station.
Description
Technical field
The present invention relates to a kind of high-efficient multi-pipe spiral demist dust pelletizing system, can be widely used in the gas cleaning process of coal burning boiler of power station wet method fume desulfurizing system.
Background technology
Demist deduster is the key equipment in wet method fume desulfurizing system, flue gas after desulfuration absorbing tower process carries a large amount of slurry drop, these drops include solid content or DDGS, they mainly absorb the flue dust of the product after SO2, superfluous desulfurizing agent and collection at large, if do not removed, these drops by depositing, block, fouling and secondary pollution, gypsum rain, the series of problems such as follow-up equipment corrosion.The function of demist deduster is exactly remove these drops as far as possible, carries out gas-water separation to the flue gas after desulfurization, and the performance of demist deduster not only affects the safe and reliable operation of desulphurization system, and directly affects discharge index.
At present, existing demist deduster is generally deflection plate demist deduster, and deflection plate demist deduster has flat, ridge type, the multiple arrangement such as combined, and in its outlet droplet content flushing cycle, average guarantee value is 75mg/Nm
3pressure drop is generally less than 200Pa, ridge type demist deduster critical separation particles 20 ~ 30 μm, in actual moving process, owing to affecting by factors such as flue gas flow rate, slurries dust content, blade construction, blade pitgh and demist deduster layouts, do not take the gas cleaning treatment measures such as wet cottrell as follow-up, be difficult to ensure thermal power plant smoke dust discharge concentration≤20mg/Nm
3basic demand, even if but follow-up increase wet static dedusting technology will realize≤5mg/Nm
3the index of ultra-clean discharge is also very difficult.
Summary of the invention
The object of the present invention is to provide a kind of high-efficient multi-pipe spiral demist dust pelletizing system of high, the ultra-clean discharge of a kind of demist efficiency of dust collection.
In order to achieve the above object, a kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, comprise shell body, several fixed supports of shell body inside are arranged at short transverse interval, be distributed in shell body inside and the vertical demist dedusting assembly be made up of several tubular helical demist dedusters be arranged between two fixed supports, be arranged on the rinse-system on fixed support.
A kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, several tubular helical demist dedusters said, each tubular helical demist deduster comprises the outer cylinder be arranged on fixed support, helical axis, is positioned at outer cylinder and is arranged on the helical blade on helical axis.
A kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, described helical blade, is provided with several radial holes.
A kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, said helical blade, can adopt single head structure, also can adopt bull structure.
A kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, said demist dedusting assembly, according to fume emission and resistance, enclosure interior can be arranged by individual layer outside, also can multilayer arrange.
A kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, all arranges rinse-system at every layer of demist dedusting assembly upper-lower position.Flushing water pressure, the water yield and the flushing frequency set according to actual operating mode.
A kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, its operation principle is: the flue gas containing desulfurization slurry and dust enters from demist dedusting assembly bottom, due to the guide functions of helical blade, flue gas constantly changes flow direction in flow at high speed process, helically rise, slurries in flue gas clash into mutually probability and obviously increase, be conducive to coalescence and become coarsegrain slurries, the bulky grain slurries formed get rid of outside cylinder inner wall by centrifugal action, outer cylinder moisture film is formed at inwall, act on helical blade surface by inertia force simultaneously and also form moisture film, moisture film absorbs dust in the slurries constantly clashed into again further, slurry pool is flowed into along inwall and conveyor screw surface, helical blade is along the circumferential direction provided with radial hole, these holes form moisture film, flue gas is in uphill process, part dust and slurries will certainly impact moisture film hole, and stopped in moisture film hole, absorb, then next moisture film is formed, go round and begin again, complete efficient demist dedusting function.In addition, the radial hole that the blade of helical blade is arranged, produces turbulent flow by the axial flow of this some holes and spiral air flow, is suitable for the coalescence promoting the fine particulates such as drop, dust, is also conducive to improving dedusting demisting efficiency.
A kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, increase the collision probability of dust, make fine dust coalescence, be conducive to removing the fine dust in flue gas, can slurry drops entrained by efficient removal flue gas and aerosol particle thing, the aerosol particle things such as the ammonium sulfate that efficient removal is formed because of the escaping of ammonia, and the heavy metal Hg can effectively removed in flue gas and mercury oxide, demist efficiency of dust collection is high, realizes the ultra-clean discharge of flue gas.
In sum, a kind of high-efficient multi-pipe spiral of the present invention demist dust pelletizing system, demist efficiency of dust collection is high, ultra-clean discharge.
