Abstract

The utility model relates to a sour regeneration treatment groove of active carbon air agitation belongs to active carbon wet process regeneration treatment device in the gold mine cyaniding charcoal thick liquid technology. The outside fixed connection solution overflow mouth in cell body top, solution overflow pipe and solution overflow mouth below fixed connection, overhead gaseous ring and the inside fixed connection of the cone bottom of cell body, lower air ring and the inside fixed connection of the cone bottom of cell body, overhead gaseous ring are located air ring top down, inside drainage tube the inner of regeneration back solution is located the cone bottom of cell body, and be located air ring top down, arrange the cone bottom troops under one's command side that the charcoal mouth is located the cell body. The advantage is novel structure, adopts the air to stir, utilizes the air can automatic upward movement in liquid and drive liquid and flow to reach the effect of stirring, utilize the bubble to replace mechanical stirring, great reduction active carbon mechanical wear, reduced the loss of active carbon, compare with static regeneration facility, regeneration efficiency is high, regeneration effect is good.

Description

Active carbon air stirs acid regeneration treatment trough

Technical field

The utility model belongs to activated carbon wet reclamation processing unit in gold mine cyanide carbon pulp technique.

Background technology

Regenerating active carbon or activation refer to either physically or chemically on the premise of activated carbon original structure is not destroyed, The adsorbate that activated carbon capillary will be adsorbed in is removed, and is recovered its absorption property and is reached reusable purpose.Due to activity Price is higher in itself for charcoal, if only just being abandoned using once extremely uneconomical, how the activated carbon of highly efficient regeneration adsorption saturation is reaching Economical rationality is utilized, it has also become necessary key problems-solving in activated carbon industry, while being also the focus of domestic and international research and development.

The method of current regenerating active carbon mainly has the conventional regeneration methods such as hot recycling method, bio-regeneration method, wet method, while Emerging active carbon regenerating technology is also more and more, such as electrochemical process, supercritical fluid method, catalytic wet air oxidation and ultrasonic wave Method.

Hot recycling method is that industrially application is most at present, most ripe regeneration method of active carbon, primarily directed to organic matter Activated carbon is polluted, changes to realize the regeneration of activated carbon according to the different of organic matter when being heated to different temperatures；Bio-regeneration Method is the organic matter of absorption on parsing activated carbon using the bacterium by domestication, and is broken down into the mistake of carbon dioxide and water Journey；Wet type method of reproduction is under conditions of HTHP, with oxygen or air as oxidant, by the work under liquid phase state Property charcoal on adsorb oxidation operation resolve into small molecule, realize regenerating active carbon；Conventional wet reclamation method is using activity Phase equilibrium relationship between charcoal, solvent and adsorbed matter three, by changing the condition such as pH value of solvent, breaks adsorption equilibrium, Adsorbate is desorbed so as to realize regeneration method from activated carbon.Regeneration method of active carbon is a lot, cuts both ways, conventional Activated carbon wet method acid regeneration processing equipment use mechanical agitation, increased the loss of activated carbon mechanical wear and activated carbon.

The content of the invention

The utility model provides a kind of active carbon air stirring acid regeneration treatment trough, to solve what is existed using mechanical agitation Increased the problem of the loss of activated carbon mechanical wear and activated carbon.

The utility model is adopted the technical scheme that：Cell body upper outer is fixedly connected solution overfall, solution overflow pipe It is fixedly connected with solution overfall lower section, overhead compression ring is fixedly connected with inside the conical bottom of cell body, lower air ring and cell body It is fixedly connected inside conical bottom, overhead compression ring is located at lower air ring top, the Drainage pipe of solution is inner after regeneration is located at cell body Conical bottom inside and positioned at lower air ring top, carbon outlet port be located at cell body conical lower portion lower section.

There is stomata one on the overhead compression ring.

There is stomata two on the lower air ring.

There is filter screen the inner of the Drainage pipe of solution after the regeneration.

The utility model has the advantages that structure is novel, it is stirred using air, in a liquid can be from trend using air It is upper motion and drive liquid to be flowed, so as to reach the effect of stirring, mechanical agitation is replaced using bubble, greatly reducing Activated carbon mechanical wear, reduces the loss of activated carbon, and compared with static regeneration equipment, regeneration efficiency is high, favorable regeneration effect, no The incomplete situation of regenerating active carbon can be produced, due to air stirring can also isolating active carbon surface some other materials, So that regenerating active carbon effect is more preferable.

Specific embodiment

The upper outer of cell body 1 is fixedly connected solution overfall 6, and solution overflow pipe 7 is fixedly connected with solution overfall lower section, Overhead compression ring 2 is fixedly connected with inside the conical bottom of cell body, and lower air ring 4 is fixedly connected with inside the conical bottom of cell body, overhead Compression ring 2 is located at the top of lower air ring 4, and the Drainage pipe 3 of solution is inner after regeneration is located inside the conical bottom of cell body and is located at down The top of air ring 4, carbon outlet port 5 is located at the conical lower portion lower section of cell body.

There is stomata 1 on the overhead compression ring.

There is stomata 2 401 on the lower air ring.

There is filter screen 301 the inner of the Drainage pipe 3 of solution after the regeneration.

Operation principle, overhead compression ring 2, lower air ring 4 are connected with the air compressor machine or air pump of outside, to blowing air in cell body, Liquid is stirred, can upwards be moved automatically in a liquid using air and be driven liquid to be flowed, so as to reach stirring Effect, solution overfall is used for overflow, and solution is discharged by Drainage pipe 3 after regeneration, and activated carbon is by carbon outlet port after regeneration Discharge.
