Abstract
The invention discloses a recycling method of nutshells. The recycling method comprises the following steps: cleanly washing the nutshells; drying and crushing the nutshells; sieving by a molecular sieve to obtain powder; adding rosin and uniformly mixing; conveying the mixture into a carbonization furnace; heating the mixture to 650-750 DEG C at a temperature rising speed of 5 DEG C/minute-8 DEG C/minute; carbonizing for 1-1.5 hours; cooling the mixture to 300-400 DEG C at a cooling speed of 10 DEG C/minute-15 DEG C/minute; carbonizing for 0.5-0.8 hour; and cooling to obtain amorphous particle active carbon. The active carbon is prepared by taking the waste nutshells as the raw material; a production method is simple and feasible, and comprehensive utilization of resources is realized; wastes are changed into valuable things; and the prepared active carbon has good adsorption performance and can be widely applied to the fields of chemical engineering, food, environment protection, electric power and the like.
Description
Technical field
The present invention relates to reusing of energy source technical field, especially a kind of regeneration method of nutshell.
Background technology
Nut because of its kernel possess abundant nutritive ingredient, and have the title such as " long-lived fruit ", " anticancer fruit ", " peanut ".Containing in daily life, after people eat kernel, abandon by nutshell or burn.According to research reports, nutshell is a kind of biomass resource being rich in the materials such as xylogen, Mierocrystalline cellulose, hemicellulose, if it directly abandoned or burn, must cause the significant wastage of resource.Therefore, strengthen the comprehensive utilization to nut-shell, avoid the waste of nut-shell resource, the product that production added value is high, not only effectively can process solid waste, and can turn waste into wealth, improve income.
Summary of the invention
The object of this invention is to provide a kind of regeneration method of nutshell, the regeneration method of this nutshell can solve the problem of the nutshell wasting of resources.
In order to solve the problem, the technical solution used in the present invention is:
The regeneration method of this nutshell comprises the following steps:
A, nutshell to be cleaned up, dry, pulverize, cross 50 order ~ 100 order molecular sieves, obtain nut shell powder;
B, in described nut shell powder, add rosin, mix, proceed to charring furnace, with the heat-up rate of 5 DEG C/min ~ 8 DEG C/min, be heated to 650 DEG C ~ 750 DEG C, carbonization 1 hour ~ 1.5 hours;
C, with the cooling rate of 10 DEG C/min ~ 15 DEG C/min, be cooled to 300 DEG C ~ 400 DEG C, carbonization 0.5 hour ~ 0.8 hour, cooling obtains indefinite form granulated active carbon.
In technique scheme, scheme can also be more specifically: described nutshell is selected from the one wherein such as melon seed cases, nut-shell, pine nut shell, hazelnut shell or this is multiple.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention is with discarded nutshell for gac prepared by raw material, and making method is simple, achieves the comprehensive utilization of resource, turns waste into wealth, and prepared charcoal absorption performance is good, can be widely used in the fields such as chemical industry, food, environmental protection, electric power.
