(2) background technology
Existing absorbent charcoal adsorber is generally adsorption tanks, is filled with active carbon in jar, and active carbon can take place saturated after absorption a period of time.In case adsorb saturatedly, the gas peculiar smell that active carbon has adsorbed can discharge on the contrary, endangers consumer's health (particularly pernicious gas formaldehyde) again, promptly becomes pollution sources on the contrary.In addition, existing activated carbon adsorptive capacity also has much room for improvement.
(3) summary of the invention
Technical problem to be solved by this invention is to provide a kind of never saturated absorbent charcoal adsorber.
Technical problem to be solved by this invention also is to provide a kind of active carbon of high adsorption capacity.
Described absorbent charcoal adsorber comprises active carbon and adsorption tanks, and described adsorption tanks are made up of urceolus and the inner core that is nested in the urceolus, and urceolus and inner core barrel are respectively equipped with passage; Be provided with the anion distributor pipe between urceolus and the inner core, the anion distributor pipe connects anion generator; Active carbon is distributed in around the anion distributor pipe.
Preferably, described inner core cavity is provided with blower fan.Blower fan can promote air to carry out Filtration Adsorption through active carbon.
Anion generator of the present invention can produce anion; Contact with active carbon through each anion distributor pipe; Harmful substance oxidation Decomposition such as the formaldehyde of charcoal absorption, thus the charcoal absorption state becomes unsaturatedly by saturated, and active carbon can continue to be adsorbed with harmful substances.Anion generator can be controlled the working time that produces anion, waits to free to quit work automatically after decomposition finishes.
Preferably, described active carbon adopts following step preparation and gets:
(1) with relative molecular weight be 250000～350000, deacetylation is that 95～99% shitosan is dissolved in the diluted acid, processes chitosan concentration and be 1～5% shitosan acid solution;
(2) add powdered cellulose and stirring, use again alkali lye handle to pH be 8～10, the cohesion shitosan;
(3) dehydration, drying adds the coconut husk powdered carbon then, and granulation forms active carbon;
Above-mentioned cellulose: shitosan acid solution: the weight ratio of coconut husk powdered carbon is 3～6: 40～60: 40～50.The active carbon that makes by above-mentioned steps has the ability of powerful absorbing formaldehyde and benzene class pernicious gas.
Preferably, in the described step (1): the shitosan relative molecular weight is 310000, deacetylation is 98%, and diluted acid is a watery hydrochloric acid.
Preferably, the chitosan concentration of shitosan acid solution is 2% in the described step (1).
Preferably, alkali lye is 5%NaOH solution described in the described step (2), use alkali lye handle to pH be 9.The consumption of alkali lye is to reach pH9 for the most suitable.
Preferably, adopt the heated-air drying of centrifugal dehydration and 100 ℃ in the described step (3).
Preferably, said cellulose: shitosan acid solution: the weight ratio of coconut husk powdered carbon is 5: 50: 45.
The present invention produces anion through adopting negative ion generating device, in time will adsorb saturated active carbon by anion and carry out the oxidized activating disintegrating and regeneration, the absorption that active carbon can be continued forever.The active carbon that the inventive method makes has the ability of powerful absorbing formaldehyde and benzene class pernicious gas.
