Abstract
The invention relates to a carbon dissolving and decoloring method. The method comprises the following steps of: pre-mixing activated carbon with water in a carbon dissolving tank equipped with an air induction device at the tank port, stirring by substituting a stirring device with compressed air, and decoloring the substances to be decolored with the sufficiently mixed carbon-water compound. According to the invention, the air induction device installed at the tank port of the carbon dissolving tank effectively avoids the flying phenomenon of activated carbon, reduces environmental pollution and harm to workers and reduces the loss of activated carbon; the compressed air is used to substitute the stirring device, which reduces mechanical wear, reduces maintenance cost, simultaneously reduces electric power consumption and saves energy; and the pre-mixing of activated carbon and water increases the contact area of activated carbon and the substances to be decolored, greatly increases the decoloring reaction speed, shortens reaction time and greatly improves the quality and yield of the decolored substances.
Description
Technical field
The present invention relates to a kind of molten carbon decoloring method.
Technical background
At present in the pharmaceutical engineering the general gac that adopts to the medicine processing of decolouring.Its process is generally: after medicine dissolution is in bleacher, directly add gac in bleacher.Because gac is a kind of very light pulverous atrament, in the process of adding, can cause very big dust pollution, and cause the loss of material, environment and production are all caused very big influence.
Summary of the invention
The purpose of this invention is to provide a kind of molten carbon decoloring method that can reduce environmental pollution and loss of material and effectively improve wait to decolour material mass and output.
The present invention solves the problems of the technologies described above the technical scheme of taking:
A kind of molten carbon decoloring method, it is characterized in that described method comprises the steps: to add entry in the jar mouth is fitted with the molten charcoal jar of blower unit, open blower unit, in described molten charcoal jar, drop into gac from the jar mouth then, in described molten charcoal jar, feed pressurized gas again and stir the mixture that obtains gac and water, at last the mixture of described gac and water is injected the bleacher that the material of waiting to decolour is housed and decolour; The weight ratio of gac and water is 1:5-10 in the described molten charcoal jar; The material of waiting in the described bleacher to decolour mixes with its weight 3-3.5 water doubly and obtains mixed solution, and the mixture of described gac and water and the weight ratio of described mixed solution are 1:5-7.
Material described to be decoloured is Paracetamol, 4-novalgin or quinizine.
A kind of molten charcoal jar of implementing above-mentioned molten carbon decoloring method is characterized in that it comprises tank body, is fitted in the jar mouthful blower unit of locating of tank body and feeds a jar intravital pressurized gas pipeline.
Two sections pressurized gas outlet sections of described pressurized gas pipeline are symmetric circular arc.
Beneficial effect of the present invention: the jar of the molten charcoal jar mouthful blower unit that increases has effectively been avoided the phenomenon of dispersing of gac among the present invention, has reduced to the pollution of environment with to workman's harm, and has reduced the loss of material of gac; The inventive method adopts pressurized air to replace whipping appts, has reduced mechanical wear, has reduced maintenance cost, has reduced power consumption simultaneously, has saved the energy; Two sections pressurized gas outlet sections are symmetric circular arc, and jar interior water is rotated to same direction, make gac and water thorough mixing; Because gac and water are pre-mixed, strengthened gac and the contact area of the material material of waiting to decolour, accelerated the speed of response of decolouring greatly, shortened the time of reaction, make the quality of the material of waiting to decolour and output that by a relatively large margin raising all be arranged.
