ActiveCN101362076AAffect the life cycleAffect the service lifeCombustible gas purificationFilter regenerationActivated carbonOperational costs
The invention discloses a regeneration method of an activated carbon absorbent. The activated carbon absorbent with absorption saturation is treated by adopting a steam regeneration method; at the time when the regeneration of the steam is stopped, circulative steam is formed between the entrance and the exist of an absorbing apparatus; a purified water spraying device is arranged on a steam circulating pipe; the circulative steam is cooled off after passing through the purified water spraying device; the circulative steam with lowered temperature is utilized for carrying out cooling processing to an activated carbon bed; and the cooled activated carbon absorbent can be further dried by feeding air. In the regeneration method of the activated carbon absorbent, the adoption of steam regeneration causes that comparatively thorough regeneration of absorption capacity can be carried out under higher temperature, thereby greatly reducing the steam or nitrogen needed by the existing temperature reduction method, greatly lowering operational cost and improving the economic performance of the activated carbon absorption technology.

The invention provides a novel visible color-changing air purification material, which is prepared from L zeolite molecular sieve and copper element, wherein the adding amount of the copper element accounts for 1-5% of the mass of the L zeolite molecular sieve; the copper element is dispersed on active sites of the L zeolite molecular sieve in a form of Cu<2+>. The air purification material provided by the invention can effectively degrade harmful gases in the air by means of catalytic oxidation, has high treatment efficiency and large treatment capacity, is free from secondary pollution, doesnot have the problems of absorption saturation and the like, can be used for removing pollutants in the air in closed systems such as the interior of a vehicle or a room, and is low in manufacturingcost and simple in preparation process, thus being suitable for industrial scale-up production; the novel visible color-changing air purification material also has an obvious visual color-changing function; the color of the material can be changed obviously when the purification function of the material fails, so that a user is prompted to replace a new material in time.
