Prospect of activated carbon: the processes of extracting gold from ore pulp or solution by activated carbon adsorption include carbon pulp method (CIP method), carbon leaching method (CIL method) and carbon column method (CIC method)
Their processes basically include the following steps: (1) adsorbing and leaching gold from ore pulp or solution with activated carbon to produce gold loaded carbon; (2) The gold loaded carbon is desorbed to transfer the gold on the carbon back into the solution to produce the desorbed precious liquid of gold; (3) Using various methods to extract gold from gold bearing precious liquid; (4) The desorbed lean carbon is regenerated, its activity is restored, and then returned to the adsorption operation for reuse
Application scope of activated carbon adsorption tank:
The activated carbon adsorption box is mainly used for the treatment of organic waste gas with large air volume and low concentration
Activated carbon adsorbent can treat and purify a variety of organic and inorganic pollutants: benzene, ketone, alcohol, ether, alkane and their mixed organic waste gas, acid waste gas and alkaline waste gas; It is mainly used for making Yao, smelting, chemical industry, machinery, electronics, electrical appliances
Painting, shoemaking, rubber, plastic, printing and environmental desulfurization, deodorization and purification of harmful waste gas generated by various industrial production workshops
Structure and composition of activated carbon adsorption device:
It is composed of activated carbon adsorption purification device, desorption purification device, adsorption fan, desorption fan, etc
Use method and replacement cycle basis of activated carbon adsorption paint mist treatment box:
The activated carbon adsorption box can generally be made of stainless steel, carbon steel and PP materials, and the appropriate materials can be selected according to the nature of waste gas
The thickness of the main structure shall be based on the model and processing capacity, and shall have sufficient reinforcement to bear the load required by the structure and operation, and provide the necessary operation platform
The flow rate of the adsorbent layer of the activated carbon device shall be determined according to the adsorbent form
When granular adsorbent is used, the gas flow rate should be less than 0
60ms; When using fibrous adsorbent (activated carbon fiber felt), the gas flow rate should be less than 0
15ms; When honeycomb adsorbent is used, the gas flow rate should be less than 1
20ms
Performance profile:
Activated carbon is a kind of very small carbon particles with large surface area, and the smaller pores of CNOOC in the carbon particles
Pores have strong adsorption capacity
Due to the large surface area of carbon particles, they can fully contact with gas (impurities)
When these
The gas (impurity) is adsorbed when touching the capillary and plays a role of purification
The essence of activated carbon adsorption is a process of adsorption and concentration
live
The activated carbon adsorption tower is made of FRP, SUS, PP, carbon steel and other materials
It uses the characteristics of activated carbon adsorption to remove waste gas with low concentration and large air volume
The organic solvent in the gas is adsorbed into activated carbon and concentrated, and the gas purified by activated carbon is directly evacuated
Use of activated carbon adsorption:
The activated carbon adsorption box is mainly used for the treatment of organic waste gas with large air volume and low concentration; Activated carbon adsorbent can treat and purify a variety of organic and inorganic pollutants: benzene, ketone, ether, alkane and their mixed organic waste gas, acid waste gas and alkaline waste gas; It is mainly used in Yao making, smelting, chemical industry, machinery, electronics, electrical appliances, coating, shoemaking, rubber, plastics, printing, environmental desulfurization and deodorization, as well as the purification of harmful waste gas generated by various industrial production workshops
