Description
Technical field
The present invention relates to gac preparing technical field, particularly a kind of method and gac preparing gac.
Background technology
In prior art, stalk is the subsidiary product of agriculture production, and as agriculture production big country, the annual stalk output of China can reach 700,000,000 ~ 800,000,000 tons, add that forestry waste is as bamboo branch, wood chip, afforestation lop etc., produce agriculture and forestry organic waste material per year and reach more than 1,000,000,000 tons.Sichuan is as the large province of National Agricultural, and the annual agriculture and forestry organic waste material produced reaches more than one hundred million ton.Every autumn harvest of ripening in summer, the information of crop straw burning is just constantly transmitted in various places, and city is shrouded by gray haze, and occur the materials such as a large amount of PM2.5 suspended substances in air, visibility meter sharply declines, and causes trip difficulty.Crop straw burning remains incessant after repeated prohibition, and solve the problem of crop straw burning, should, in advance for stalk finds a way out, allow more refuse become resource.The purposes of current agriculture and forestry organic waste material resource is mainly used in the aspects such as straw-returning, straw feed, fuel, but owing to there is straw transportation inconvenience, disperseing the reason comprehensive utilization ratios such as difficulty is collected, treatment technology falls behind less than 50%, remaining waste is burned or is abandoned, not only have impact on the hygienic condition in rural area, agriculture and forestry organic waste material burns and also creates huge environmental pollution.
Therefore, how to improve the utilization ratio of stalk, the environmental pollution that containment crop straw burning causes becomes a kind of required.
Summary of the invention
For this reason, the invention provides a kind of method preparing gac, solve crop straw burning in prior art and easily bring environmental pollution, and how further by technical problem that the root, stem and leaf of discarded plant is recycled.
For this reason, the invention provides a kind of method preparing gac, comprise the steps:
Crushing material: roots of plants, stem or leaf are pulverized as length is no more than the section shape of 5cm by material chopping mechanism;
Material forming: above-mentioned section of shape roots of plants, stem or leaf are squeezed into lumpy material by material forming device;
Material carbonization: be charcoal block by above-mentioned lumpy material carbonization by charring furnace;
