The invention discloses an additive and a method for reinforcing separation of manganese and iron through magnetic roasting-magnetic separation of a high-iron manganese oxide ore. The additive consists of dithionic acid manganese, sodium sulfite and sodium humate by a certain mass ratio; the method comprises the following steps: after being evenly mixed with the additive, a high-iron manganese ore crushed and grinded to a certain particle size is sequentially agglomerated, dried, reduced and roasted; crushing, ore grinding, magnetic separation and solid-liquid separation are conducted on the roasted product after the roasted product is cooled; then magnetite powder, manganese sulfate-enriched filtrate and nonmagnetic residues are obtained. The additive and the method are adopted to reduce and convert iron oxide to the magnetite powder as blast furnace ironmaking raw materials; manganese oxide is reduced and converted to manganese sulfate, is introduced in the filtrate after the ore grinding, the magnetic separation and the solid-liquid separation, and can be used as raw materials for producing the manganese sulfate and electrolytic manganese after being purified and decontaminated. The additive and the method overcome the defect of incomplete separation of the manganese and iron in the conventional high-iron manganese ore treatment methods, and have such characteristics as high iron and manganese separation efficiency, simple process flow and low cost.

The invention provides a process method for crystallizing and separating glucose from ionic liquid by an anti-solvent method to obtain a pure product. The process method for separating the glucose from the ionic liquid by the anti-solvent method comprises the following process that firstly, dissolving the glucose into the ionic liquid at a certain temperature; and then adding an anti-solvent into the homogeneous mixed solution to crystallize and separate the glucose. The solid glucose obtained by crystallization is separated out from the solvent by filtering and then the anti-solvent in the residual solution is removed in a spin steaming mode to obtain the mixed solution of the ionic liquid and a trace amount of glucose, so that the aim of repeatedly using is fulfilled.

The invention provides suction type pneumatic conveying equipment. The suction type pneumatic conveying equipment comprises a storage cylinder, a conveying pipe, a gas pipe, a fan and a separating cylinder; the separating cylinder is embedded and welded in the top of the storage cylinder; the conveying pipe is embedded and welded in one side of the separating cylinder; the gas pipe is embedded andwelded in the other side of the conveying pipe; one end of the gas pipe is embedded and welded in the fan; a discharge pipe is embedded and welded in the bottom of the storage cylinder; the bottom ofthe discharge pipe is sleeved with a screw cap in a threaded mode; one side of the conveying pipe is welded to the storage cylinder through a support rod; a carrier plate is welded to the top of theseparating cylinder; and a motor is welded to the top of the carrier plate. A separating pipe is driven by a disc to rotate at a high speed, in the movement process of the separating pipe, due to rotation of the separating pipe, the separating pipe can lay down materials in the separating pipe before the materials fall off from the separating pipe, so that the materials fall into the separating cylinder, the materials are completely separated from airflow, and thus the materials can be completely separated from airflow just through one time of separating.

The invention relates to the field of water treatment, and discloses a continuous salt production method and system. The method comprises: (1) performing nanofiltration separation to salt-containing water to obtain nano-filtered product water and nano-filtered concentrated water; (2) performing heat transfer between the nano-filtered concentrated water and low-temperature crystallization product water obtained from the step (4) to obtain cooled nano-filtered concentrated water and warmed crystallization product water, and dividing the warmed crystallization product water into reflux crystallization product water and low temperature crystallization water product water concentrated water; (3) cooling the nano-filtered concentrated water; (4) performing low temperature crystallization separation to the cooled nano-filtered concentrated water to obtain crystallization product water and crystallization salt, and when the content X% of divalent anion salt in raw water is less than 5wt%, allowing R1<X / (5-X) to be satisfied, wherein R1 is the volume flow ratio of the low temperature crystallization water product water concentrated water to the nano-filtered product water; and (5) performing denitration crystallization to the low temperature crystallization water product water concentrated water through a barium method. The salt-containing water contains raw water and reflux crystallization product water. The method allows high-purity single-component salt to be continuously produced and is low in energy consumption and cost.

The invention provides a treatment process of copper, mercury, selenium, lead, gold and silver in a copper smelting lead filter cake. The process mainly comprises following steps of low-temperature high-pressure oxidizing leaching of copper, normal-pressure oxidizing leaching and removal of mercury, replacement of selenium and vulcanization mercury sediment and further comprises rare precious system treatment and electrodeposition copper removal treatment. The treatment process is thorough in copper, mercury, selenium, lead, gold and silver separating effect, the gold, silver and selenium arebasically and completely enriched in the slag phase, the copper recycling rate is about 96%, the leaching rate of mercury is above 90%, and the aim of comprehensively treating valuable elements is achieved.

The invention discloses a multistage cyclone separation dust collection device which comprises a dust collection cup; a first-stage cyclone channel and a second-stage cyclone channel are arranged in the dust collection cup, the first-stage cyclone channel and the second-stage cyclone channel communicate through a second-stage separation inlet, and the second-stage cyclone channel and a clean air outlet communicate through a second-stage separation outlet; a third-stage cyclone channel is further arranged in the dust collection cup, the first-stage cyclone channel and the third-stage cyclone channel communicate through a third-stage separation inlet, and the third-stage cyclone channel and the second-stage cyclone channel communicate through a third-stage separation outlet; and air in the first-stage cyclone channel is subjected to three times of direction change in the process of entering the second-stage cyclone channel through the three-stage separation inlet, the third-stage cyclonechannel and the third-stage separation outlet. A new separation path is added on the basis of an original separation path; and on one hand, the situation that the separation effect is weakened due toblockage of the original separation path is avoided, and on the other hand, the separation path length in the whole separation process is increased by the new separation path, so that the separationprocess is completer.
