1. BS-J type desorption carbon regeneration rotary kiln This equipment is designed by China Nonferrous Metals Institute and produced by internal machine. It is mainly used for desorption and regeneration of desorption charcoal in carbon slurry process gold selection plant. It can also be used for roasting operation and drying of certain raw materials. Dehydration work.
The working principle of the rotary kiln is that the carbon is contaminated by the organic matter in the slurry during the carbon selection process. After analysis, the organic matter is still attached to the charcoal, and some are immersed in the micropores of the carbon, thereby losing the gold concentrate. Adsorption. The equipment heats the charcoal to 700~800 °C to burn off the organic matter. Because of the lack of oxygen in the cylinder, the carbon loss is very small, and the carbon is restored to its original nature after cooling.
Its characteristics are as follows: 1 the residence time of the material in the cylinder can be adjusted; 2 the heating material temperature can be controlled; 3 the feeding amount can also be controlled;
4 Good working conditions and convenient operation.
The technical performance of the rotary kiln is shown in Table 1. The structure and dimensions are shown in Figure 1. The basic dimensions of the installation are shown in Figure 2.
2. Vertical activated carbon regeneration furnace The vertical activated carbon regeneration furnace adopts the principle of forced discharge regeneration. It is developed by Zhangjiakou Dongping Gold New Technology Co., Ltd. (hereinafter referred to as Dongjin) based on the previous experience of carbon regeneration. The production application proves that this type of regenerative furnace overcomes the shortcomings of the traditional regenerative furnace electrode short life, intermittent production, human operation, and relatively large loss rate. It not only inherits the advantages of traditional equipment but also has its own unique features.
The heating electrode of the conventional regenerative furnace is alternately exposed to the air at a high temperature when compared with the thin river, and is easily oxidized when the river is cold and hot; therefore, its life is relatively short. The vertical activated carbon regenerative furnace has a very thick electrode; it is always buried in the charcoal without contact with air and has a constant temperature; thus its life is multiplied. The traditional regenerative furnace is intermittently produced, and the charging-heating-discharging-activation is a working cycle. The procedure is complicated and easy to malfunction, and also requires human operation. The vertical activated carbon regeneration furnace is continuously produced, and only the raw materials need to be prepared, and the regeneration process is automatic. get on. Because the traditional regenerative furnace activated carbon is in contact with air for a period of time, it will inevitably cause oxidation loss; the activated carbon in the vertical activated carbon regeneration furnace is activated and cooled in the furnace, the temperature rise-activation is continuously completed and the carbon particles move slowly, and the loss Smaller, but difficult to measure in practice.
Since the temperature rise of the carbon is completed by the conductivity of the carbon itself, and the carbon is continuously moved in the regeneration furnace, the carbon in the carbon storage tank is extremely charged, posing a threat to the personnel and the environment. The company has successfully solved this problem with special isolation technology, which makes the product more reliable and secure.
Its technical performance: continuous discharge, automatic control in the whole process, drying, heating, activation once completed, regeneration temperature 700 ° C ~ 900 ° C, regeneration efficiency (recovery performance recovery rate) ≥ 95%, regeneration loss rate ≤ 1%, voltage 380V .
The main parameters of the vertical activated carbon regeneration furnace are shown in Table 2, and the appearance is shown in Figure 3.
3. JHR-O series fuel-type activated carbon regeneration furnace JHR-O series fuel-type carbon regeneration furnace was developed by Changchun Gold Institute in recent years. This is the first equipment in China that uses diesel as a heat source to regenerate activated carbon. The existing activated carbon regeneration equipments are mostly products of the 1980s. The equipment is old and aging, and the energy consumption is high. In recent years, the newly developed activated carbon regeneration equipment has too little processing capacity (the daily processing capacity is less than 1t). Therefore, this low-cost, large-volume regeneration furnace has filled the gap of domestic fuel activated carbon regeneration equipment, and is in a leading position in China, and has obtained national patents.
In the production process of the gold mine carbon slurry plant, the impurities in the slurry will seriously deteriorate the activity of the activated carbon. Even if some ions are desorbed from the activated carbon during the desorption process, the activity of the carbon will be greatly affected; It can remove most of the acid-soluble impurity scale from the carbon, and will seriously damage the pore structure of the activated carbon, and the organic matter adsorbed on the activated carbon cannot be removed. In this way, the activated carbon can only be improved by the heat treatment method. The heat treatment not only removes the organic matter, but also expands the pores of the carbon to form an oxidation active center on the surface of the carbon, so that the carbon activity can be fully recovered.
The working principle of JHR-O series fuel regenerator: the adsorption activity of activated carbon is mainly due to its huge internal surface area and pore distribution. In the charcoal-adsorbed slurry, large-molecule organic substances such as collectors , foaming agents, oils, and humic acids such as xanthate are also adsorbed by carbon, making the activated carbon particles hydrophobic, or contaminating the active surface in the carbon, or occupying The adsorption active point in the pores of the carbon, or the microporous channel blocking the carbon, damages the adsorption performance of the carbon and affects the original activity of the activated carbon. Pickling and removed only calcium carbonate, magnesium carbonate, silica scaling, and other quality iron, macromolecular organic pollutants are burned off only by way of high temperature heat treatment, so that the activated carbon regeneration. The heat treatment not only removes the organic matter, but also expands the pores of the carbon, so that the carbon has more oxidation active surface and pores, so that the activity of the carbon is fully recovered.
JHR-O series fuel regeneration furnace regeneration process introduction: The carbon to be recycled is passed through the carbon bucket, and the automatic supply of carbon is completed through the carbon level control and time relay. When the furnace body is filled with charcoal, the burner is started, the furnace body is heated, the furnace temperature and the carbon temperature are continuously increased, and the carbon temperature reaches 650 ° C in about 3 hours, and the temperature-controlled thermocouple transmits the signal to the carbon motor control component. The charcoal motor rotates to discharge the regenerated charcoal. The carbon temperature is higher than (equal to) 650 ° C, the carbon removal process is carried out, the carbon temperature is lower than 650 ° C, and the carbon removal stops. At this time, the furnace temperature is controlled to be 670 ° C ~ 690 ° C. The upper and lower limits of the temperature control table are used to control the burner. When the furnace temperature is higher than the upper limit of 690 °C, the furnace is turned off, and the furnace temperature is started when the furnace temperature is lower than the lower limit of 650 °C. The carbon temperature and the furnace temperature are double controlled to ensure that the carbon temperature reaches 650 °C. When a certain amount of charcoal is used to lower the carbon level below the set value, the carbon level controller will give a signal to the charcoal motor, so that the charcoal motor feeds the furnace under the control of the time relay.
JHR-O series regenerative furnace realizes operation automation, double temperature control, stable performance, good activated carbon index and low operating cost.
Economic Benefits JHR-O series fuel regenerative furnace not only has high technical index, superior performance, but also significant economic benefits, mainly because of low production cost and high combustion calorific value of diesel. The calorific value of 1L diesel combustion is equivalent to 11.4kW electric energy. The results of applying this regenerator in a gold mine in Hebei show that the same treatment of 1t desorbed carbon JHR-O-2000 fuel-type regenerative furnace can save 332 yuan compared with 81kW carbon regenerative electric rotary kiln.
Social benefits: In the production of carbon mines in China's gold mines, because there is no particularly effective activated carbon regeneration equipment, most mines do not regenerate the inactive carbon, but incinerate them to extract residual precious metals, resulting in serious waste of resources; The new carbon is re-invested in production, and the purchase cost of new carbon is 12,000 yuan per ton, resulting in an increase in production costs.
