Description
Technical field
The utility model relates to the flue gas desulfurization technique field, is specifically related to the separation, impurity removal device of a kind of white clay/acetylene sludge-gypsum process desulphurization gypsum slurries.
Background technology
Do in the white clay of sweetening agent/acetylene sludge-gypsum process flue gas desulfurization course with white clay/carbide slag, water-insoluble impurity in white clay/carbide slag and from the constantly accumulation in the absorption tower of the grey branch in the flue gas, form particle diameter below 45 μ m, true density is at 1.5～1.8g/cm
3Between the black suspension mixture, be called for short the black suspension thing.The black suspension thing is accumulated in the gypsum slurries, has reduced the stability of desulfuration efficiency and desulphurization system.After the black suspension thing enters dewatering system with the desulfurated plaster discharge, because the hydrocyclone separation technology poor effect, during the dehydration of vacuum band filter, the black suspension thing can stick on filter cloth, the gypsum surface, make the gypsum dehydration difficult, gypsum purity reduces simultaneously, and quality descends.
Notification number is dewatering and the device that the Chinese invention patent of CN1325419C discloses a kind of flue gas desulfurization gypsum slurry, next door at desulfuration absorbing tower connects drying tower, the gypsum slurries vent pipe of desulfuration absorbing tower bottom is connected to the spraying plant on drying tower top through the gypsum overboard pump, the first tributary pipe of former flue, booster fan through series connection, parget water sub-controller or smoke distributor are communicated to the mouth that advances of drying tower bottom, the drying tower bottom is provided with the gypsum displacer, the second tributary manifold of the pipe of drying tower and former flue closes, and being communicated to the mouth that advances of desulfuration absorbing tower, the smoke-uptake of desulfuration absorbing tower is connected with chimney.This device takes full advantage of former flue gas heat, finish the dehydration of desulfurated plaster slurries with lower energy consumption, hydrocyclone and the vacuum belt machine of conventional dehydration system have been saved, be applicable to the gypsum dehydration technique of wet desulfurization of flue gas by limestone-gypsum method technique, if this technique is used for the gypsum slurries dehydration of white clay/carbide slag-gypsum wet sulfur removal technology, because black suspension impurity lock outlet capacity is stronger in the gypsum slurries of white clay/carbide slag sulfur removal technology, hot flue gas can not effectively be removed this part moisture, so this technique is not suitable for the dehydration of the gypsum slurries of white clay/carbide slag-gypsum wet sulfur removal technology.
Publication number is that the Chinese patent of CN102071587A discloses a kind of method of removing black colloid substances in papermaking white mud of flue gas desulfurization absorbent, this invention is carried out the desulfurization pre-treatment to white clay, white clay is through changing the steps such as stock tank, vibratory screening apparatus, ultrasonic cleaning equipment, size-mixing tank, black jelly in the white clay is discharged with the rinse water overflow, and purity improves.Make sweetening agent with white clay after the pre-treatment, gypsum qualitt improves.Publication number is that the Chinese patent of CN102351232A discloses a kind of technique of removing ferrosilicon in the carbide slag slurries, it is the magnetic field of 0.05-0.5T by magneticstrength that carbide slag slurry sieves rear, remove ferrosilicon particle wherein, the black impurity in the desulfurated plaster is produced in the desulfurization of minimizing carbide slag, improves the quality of gypsum.Above-mentioned two kinds for the treatment of processs all are that sweetening agent is processed, and make it meet the requirement of flue gas desulfurization technique.But because white clay/and the carbide slag pre-treating technology is used limitedly, uses lessly in white clay/acetylene sludge-gypsum process flue gas desulfurization technique, and impurity affects problem to white clay/acetylene sludge-gypsum process flue gas desulphurization system and gypsum qualitt and still exists in white clay/carbide slag.
