Abstract
The invention relates to the technical field of production technologies of activated carbon products, in particular to a high-temperature carbonization preparation method of activated bamboo carbon with a high absorption rate. The preparation method comprises steps as follows: phyllostachysedulis produced in Nanping is taken as a raw material, smashed and sieved, and bamboo sawdust with a grain size of 0.2 mm-1 mm is taken and is naturally air-dried for standby application; a temperature programmed furnace carbonizes the bamboo sawdust, the bamboo sawdust is heated to the temperature of 900 DEG C at the heating speed of 5 DEG C/min and subjected to heat preservation for ten hours, and a finished product of activated bamboo carbon is obtained; a few number of finished products of activated bamboo carbon are taken and placed in a methylene blue solution and an iodine solution respectively; if the methylene blue absorption value of the finished product of activated bamboo carbon is larger than 300 mg/g and the iodine absorption value is larger than 1,000 mg/g, the standard is met; the phyllostachysedulis raw material produced in the Nanping adopts phyllostachysedulis seedlings which have been cultured for three years before planting; and the temperature programmed furnace optimally adopts a KDFS.70 model furnace made in Japan. The absorption rate of the activated bamboo carbon is highest, and the filtering effect is good.
Description
Technical field
The present invention relates to gac product producing process technical field, specifically a kind of high temperature cabonization preparation method of bamboo absorbent charcoal of high adsorption rate.
Background technology
Bamboo wood is as a kind of porous media material, and the bamboo charcoal formed after pyrolysis has special pore texture, and has certain specific surface area, is widely used in damping, the removal of obnoxious flavour and the removal of Organic Pollutants In Water and heavy metal.In recent years, along with bamboo processing industrial expansion, in its course of processing, the industrial wood waste such as a lot of bamboo shaving, bamboo bits will be there is, enterprise generally it can be used as fuel, if by bamboo wood and byproduct thereof for the preparation of link friendly sorbing materials such as bamboo absorbent charcoals, the preparation that can be bamboo absorbent charcoal provides good raw material sources.
Because bamboo charcoal source is wide, with low cost, absorption property good, increasing investigator is studied the preparation of bamboo charcoal and absorption property, can adopt different production technique according to different demands.In the preparation process of bamboo absorbent charcoal adopting high temperature cabonization method, there are 3 major influence factors, are respectively: carbonization temperature, soaking time and temperature rise rate.
Summary of the invention
The invention provides a kind of high temperature cabonization preparation method of bamboo absorbent charcoal of high adsorption rate, the adsorption rate of its bamboo absorbent charcoal is higher, good filtration effect.
Technical scheme of the present invention is as follows: a kind of high temperature cabonization preparation method of bamboo absorbent charcoal of high adsorption rate, comprises the following steps:
A, to get the mao bamboon produced Nan Ping be raw material, and after being pulverized, sieving, the bamboo of getting wherein particle diameter 0.2 ~ 1mm is considered to be worth doing, for subsequent use after natural air drying;
B, with temperature programming stove to bamboo bits carbonize, after being warmed up to 900 DEG C with the heat-up rate of 5 DEG C/min, being incubated 10 hours, obtaining bamboo absorbent charcoal finished product;
C, the bamboo absorbent charcoal finished product that takes a morsel are placed in methylene blue solution and iodine solution respectively, if the methylene blue adsorption value of bamboo absorbent charcoal finished product is greater than 300mg/g, iodine sorption value is greater than 1000mg/g, then conformance with standard.
The mao bamboon raw material choose that is produced from described Nan Ping has brought up the mao bamboon seedling of 3 years before planting; Described temperature programming stove selects Japan's KDFS.70 model processed best.So more ensure the end properties quality of bamboo absorbent charcoal.
Advantage of the present invention: the carbonization temperature that the present invention limits, soaking time and temperature rise rate 3 factor of productions, the adsorption rate of the bamboo absorbent charcoal of its correspondence is the highest, good filtration effect.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, the present invention is further elaborated.
A high temperature cabonization preparation method for the bamboo absorbent charcoal of high adsorption rate, comprises the following steps:
A, to get the mao bamboon produced Nan Ping be raw material, and after being pulverized, sieving, the bamboo of getting wherein particle diameter 0.2 ~ 1mm is considered to be worth doing, for subsequent use after natural air drying;
B, with temperature programming stove to bamboo bits carbonize, after being warmed up to 900 DEG C with the heat-up rate of 5 DEG C/min, being incubated 10 hours, obtaining bamboo absorbent charcoal finished product;
C, the bamboo absorbent charcoal finished product that takes a morsel are placed in methylene blue solution and iodine solution respectively, if the methylene blue adsorption value of bamboo absorbent charcoal finished product is greater than 300mg/g, iodine sorption value is greater than 1000mg/g, then conformance with standard.
The mao bamboon raw material choose that is produced from described Nan Ping has brought up the mao bamboon seedling of 3 years before planting; Described temperature programming stove selects Japan's KDFS.70 model processed best.Yield and the final product quality of bamboo absorbent charcoal are so more ensured.
In charring process carbonization temperature, soaking time and temperature rise rate on the impact of Bamboo Charcoal Property as following table:
Wherein 500-5-4 represents 500 DEG C of carbonization temperatures, and temperature rise rate is 5 DEG C/min, and soaking time is 4 hours.
High temperature cabonization bamboo absorbent charcoal preparation method of the present invention is in order to ensure the high absorption property of bamboo absorbent charcoal, carry out repeatedly routine tests and comprehensive test for four factor of productions of carbonization temperature, soaking time and temperature rise rate in Production Flow Chart respectively, finally obtain the production method of high absorption property of the present invention.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
