Description
Technical Field
The utility model relates to the field of application of activated carbon, in particular to an activated carbon pickling regeneration device.
Background
The activated carbon adsorption purification technology is widely used in industries such as industrial waste gas treatment, sewage treatment, mine metallurgy and the like. The activated carbon has the dual characteristics of physical adsorption and chemical adsorption, and when the activated carbon is used for adsorbing noble metals or base metals for a period of time, the adsorption speed and the adsorption capacity effect are gradually deteriorated until the adsorption reaches saturation and the adsorption capacity is lost, so that new carbon has to be replaced, not only is the resource waste caused, but also the cost is greatly increased. Therefore, it is necessary to regenerate the activated carbon from both economic and environmental points of view, and the regeneration of the activated carbon should become an important component in the technology of producing and using the activated carbon.
Common methods for active carbon regeneration include wet acid washing regeneration, pyrogenic regeneration and biological regeneration. The biological regeneration method has long regeneration time and slow recovery of adsorption rate, is not applicable to organic matters difficult to degrade, and mainly adopts a rotary furnace as equipment for fire regeneration in the prior art, and consists of a rotary cylinder body, a heat-preserving furnace body, a charging screw, a head cover, a cooling discharger, a furnace body inclination regulator, an electric control box and the like. In order to overcome the defect of fire regeneration, the following Chinese patent invention is published: CN101992079A, CN102553554a, etc., adopts a continuous circulation regeneration method for the waste powdered activated carbon, and the results of the method are ideal although the main drying and activating equipment and the process are different. The method regenerates the activated carbon by using high-temperature gas generated by air and gas combustion, wherein the high-temperature gas contains partial oxygen, so that the activated carbon is oxidized and burned out under the high-temperature condition, and the efficiency is low.
For the mine metallurgical industry, wet pickling regeneration and fire regeneration are adopted in a combined mode. The conventional active carbon pickling regenerating unit that uses at present mainly includes:
mechanical stirring type active carbon pickling regeneration tank: as shown in fig. 2, the upper end of the pickling tank 1 is an open-type opening. During operation, the activated carbon soaked in the pickling solution is stirred by the stirring paddle, so that the aim of pickling and regenerating the activated carbon is fulfilled. The following problems exist in this pickling mode: firstly, the pickling tank body is usually open, so that acid gas is dispersed in the pickling process, the operation environment is poor, and the pickling tank is not friendly to the environment; secondly, the damage of mechanical stirring to the activated carbon is large, so that the carbon loss of the activated carbon is large; thirdly, the pickling soaking time is about 6 hours each time, and the pickling time is longer.
(2) Fixed active carbon pickling regeneration tank: as shown in fig. 3, the acid pump 16 and the acid matching tank 17 are connected to the outside of the pickling tank 1. During operation, the pickling liquid is pumped into the pickling tank 1 through the acid-resistant pump 16, and circulation is carried out in the activated carbon bed layer, so that the aim of pickling and regenerating the activated carbon is fulfilled. Because the active carbon does not flow in the mode, no matter the spraying or the liquid inlet mode of 'lower inlet and upper outlet', the phenomena of 'channeling' or 'dead zone' and 'hardening' of the pickling liquid in the active carbon bed layer inevitably occur, so that the pickling regeneration effect of the active carbon is poor, the pickling time is generally about 4-5 h, and the energy consumption is high.
(3) Aeration stirring activated carbon pickling regeneration tank: as shown in fig. 4, the acid pump 16 and the acid matching tank 17 are connected to the outside of the pickling tank 1, and a circulation tube 18 is provided in the pickling tank 1, and an inflation tube 19 is provided in the circulation tube 18. During operation, the pickling liquid is pumped into the pickling tank 1 through the acid-resistant pump 16, circulation is carried out in the activated carbon bed, and high-pressure air is filled into the circulation cylinder 18 of the pickling tank 1 to disturb the activated carbon bed, so that the aim of pickling and regenerating the activated carbon is fulfilled. Because the active carbon bed layer in the disturbance mode has flowability locally, the pickling and regenerating effect is better than that of a fixed active carbon pickling and regenerating tank, but the pickling and regenerating effect is still unsatisfactory, and the pickling time is still relatively long, generally about 3-4 hours.
The utility model adopts an external active carbon air lifter mode to circularly acid-wash and regenerate active carbon, and fully flows the active carbon, so as to solve the problems of large abrasion, long acid-wash time, poor acid-wash and regeneration effect and the like of the conventional active carbon acid-wash and regeneration device.
