Description
Technical field
The utility model relates to and utilizes flyash to make active carbon, and more particularly, the utility model relates to a kind of board plug type ash multilevel flotation separation equipment.
Background technology
The main component of flyash is ash content and the unburned charcoal particle that comprises the oxides such as silica, alundum (Al2O3), di-iron trioxide, calcium oxide, magnesia, sulfur trioxide, and wherein unburned charcoal particle can be used as the raw material of producing active carbon after extracting.
Because the charcoal particle is lighter, usually use the charcoal particle in the mode extract powder coal ash of flotation.Prior art provide multiple from flyash the equipment of flotation carbon particle.For example, Chinese patent 200810031474.7 discloses a kind of flotation pillar special for fly ash, at flotation column cylindrical shell top pulp distributer is housed, establish multilayer bubbling plate in the cylindrical shell, multiple spot swirl-flow devices and multiple spot tail ash spout hole are established in the cylindrical shell bottom, install the ore pulp distributing pipe around the pulp distributer, around device circulating line, the circulating line upper end connects with the ore pulp distributing pipe, lower end and swirl-flow devices connect, ore pulp distributing pipe interface and feed inlet and outlet respectively connect the circulating pump two ends, the high charcoal balanced overflow plate of ash and the overflow of high charcoal ash also are housed on flotation column top collect mouthful, and tail ash spout hole is connected and installed with tail ash automatic control stuff box by pipeline.
And for example, Chinese patent 200920064391.8 discloses a kind of floatation column special for circulating fluidized, at the top pulp distributer is housed, in establish multilayer bubbling plate, the multiple spot swirl-flow devices is established in the bottom, the bottom is connected and installed taper tail ash feeder, install the ore pulp distributing pipe around the pulp distributer, the peripheral device circulating line, the ore pulp distributing pipe connects circulating pump, the high charcoal balanced overflow plate of ash also is housed on flotation column top and collects mouth, the tail ash tube road that its bottom of taper tail ash feeder connects is connected to tail ash automatic control stuff box.
And for example, Chinese patent 200820046239.2 discloses a kind of flyash flotation carbon process units, flyash flotation carbon process units comprises the screening module that can screen the flyash granularity, stirs module, can cleaned coal and tail ash content from flotation module, dehydration module and the conveying mechanism that becomes integral body with upper module successively organic connections.
The said equipment all is the device that flyash is carried out the one-level flotation, in the production practices, in order to obtain the higher high charcoal ash of phosphorus content with the higher active carbon of preparation quality, can carry out again flotation to the particle that the one-level flotation obtains.For example, Chinese patent 200920063583.7 discloses a kind of new equipment of producing active carbon with flyash, comprises that the former ash of flyash that connects successively advances ash bucket, electronic measuring scale, box-type ash remover, ore pulp preprocessor, first order flotation column, second level flotation column, the first thickener, the first filter, the first dryer, active carbon Special grinding, oil water separator, the second dryer; Ore pulp preprocessor and second level flotation column also are connected with the automatic medicament feeding machine of dispersant and composite floating chemical, and the active carbon Special grinding also is connected with the high steam pipeline.This equipment carries out secondary floatation by first order flotation column and second level flotation column are set to flyash, because the structure of every one-level flotation column more complicated all, the structure of this secondary floatation system is more complicated, and then causes its material cost and processing cost high; Because power consumption is large, its operating cost is higher simultaneously; In addition, its flotation effect is unsatisfactory.
