Abstract
The invention relates to a manufacturing method of silver-carrying coconut shell activated carbon. The manufacturing method comprises the following steps: repeatedly washing high-quality granular coconut shell activated carbon with RO pure water; dehydrating with a dewatering centrifuge, and further drying with a drying oven; solidifying ionized silver nitrate on the surface and in pores of the coconut shell activated carbon; and cooling the calcined coconut shell activated carbon, so as to obtain the silver-carrying coconut shell activated carbon. According to the manufacturing method disclosed by the invention, a special process of high-temperature calcination is adopted, and water washing, drying, silver carrying and cooling processes are combined, so that silver ions are in firm complexation on the surface of activated carbon, the hurt to human health due to loss of the silver ions is avoided, and the efficient bacteriostatic effect can be achieved. The manufacturing method can be applied to the field of drinking water purification.
Description
Technical field
The present invention relates to a kind of manufacture method of active carbon, relate in particular to the manufacture method of a kind of year silver-colored cocoanut active charcoal.
Background technology
Traditional carrying in silver-colored cocoanut active charcoal production process, often adopt the simple and easy method that silver nitrate and active carbon are soaked, stirred, by the method processing year silver-colored cocoanut active charcoal product out, the combination of silver ion and active carbon is unstable, easily come off along with the impact of current, cause the heavy metal silver in water to exceed standard, serious harm health, and along with the loss of silver ion, this product is substantially without any fungistatic effect.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is exactly how to make silver ion and the stable combination of active carbon, thereby plays fungistatic effect, and avoids silver ion to run off causing the infringement to health.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides the manufacture method of a kind of year silver-colored cocoanut active charcoal, it is characterized in that, comprise the following steps:
Step 1: high-quality particle cocoanut active charcoal is cleaned repeatedly with RO pure water, until dust is cleaned in the floating ash in the surface of active carbon and aperture;
Step 2: cocoanut active charcoal is dewatered with dewatering centrifuge, then cocoanut active charcoal is put into drying oven be dried, take out after dry;
Step 3: silver nitrate, RO water and ammoniacal liquor are merged, and ionization, be evenly sprayed on particle cocoanut active charcoal, then put into calcining furnace calcining, promote deep reaction, ionization silver nitrate is solidificated in cocoanut active charcoal top layer and hole;
Step 4: by calcining after cocoanut active charcoal carry out cooling, obtain carry a silver-colored cocoanut active charcoal.
The present invention also provides a kind of silver-colored cocoanut active charcoal that carries, and is obtained by the manufacture method manufacture of provided by the invention year silver-colored cocoanut active charcoal.
(3) beneficial effect
The manufacture method of of the present invention year silver-colored cocoanut active charcoal, comprises high-quality particle cocoanut active charcoal RO pure water is cleaned repeatedly; Dewater with dewatering centrifuge, be further dried with drying oven; Ionization silver nitrate is solidificated in cocoanut active charcoal top layer and hole; By calcining after cocoanut active charcoal carry out cooling, finally obtain carry a silver-colored cocoanut active charcoal.Method of the present invention is by adopting the special process of high-temperature calcination, and in conjunction with washing, dry, carrying the techniques such as silver-colored, cooling, make the surface of silver ion complexing firmly at active carbon, avoid silver ion to run off and caused the infringement to health, and can reach efficient antibacterial effect.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1: the process chart of the manufacture method of a kind of year provided by the invention silver-colored cocoanut active charcoal;
Detailed description of the invention
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples are used for illustrating the present invention, but can not be used for limiting the scope of the invention.
This enforcement provides the manufacture method of a kind of year silver-colored cocoanut active charcoal, it is characterized in that, comprises the following steps:
Step 1: high-quality particle cocoanut active charcoal is cleaned repeatedly with RO pure water, until dust is cleaned in the floating ash in the surface of active carbon and aperture;
Step 2: cocoanut active charcoal is dewatered with dewatering centrifuge, then cocoanut active charcoal is put into drying oven be dried, take out after dry;
Step 3: silver nitrate, RO water and ammoniacal liquor are merged, and ionization, be evenly sprayed on particle cocoanut active charcoal, then put into calcining furnace calcining, promote deep reaction, ionization silver nitrate is solidificated in cocoanut active charcoal top layer and hole;
Step 4: by calcining after cocoanut active charcoal carry out cooling, obtain carry a silver-colored cocoanut active charcoal.
The present embodiment also provides a kind of silver-colored cocoanut active charcoal that carries, and is obtained by the manufacture method manufacture of provided by the invention year silver-colored cocoanut active charcoal.
There is the silver-colored cocoanut active charcoal that carries that the method obtains to detect by SGS, energy efficient sterilizing, and can effectively control silver ion and separate out.This product can be contained in filter, filter cylinder or the filter core of various water quality treaters and be used as water purification, and the adsorbable chlorine residue except different in anhydrating smells, in peculiar smell, organic matter, colloid and removal water, has again bacteriostasis.
Above embodiment is only for the present invention is described, but not limitation of the present invention.Although the present invention is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is carried out to various combinations, revises or is equal to replacement, do not depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
