Abstract
The invention discloses a method for producing activated charcoal by using industrial wastes. The method comprises the steps of taking leftovers such as sawdust and wood pieces of woodworking factories as raw materials, crushing the wood pieces, adding a proper amount of organic binder into the wood powder and the sawdust, carrying out uniform mixing, carrying out extrusion forming by a high-pressure forming machine, carrying out closed heating on the formed material in a furnace for carbonization until the temperature is 800-900 DEG C, carrying out carbonization for 2-10 hours, and then, cooling the product to normal-temperature, thereby obtaining the activated charcoal. According to the method, various industrial wastes are sufficiently utilized, environment and non-renewable coal resources are protected, and all indexes of the produced activated charcoal can meet needs.
Description
Technical field
The present invention relates to a kind of changing rejected material to useful resource reutilization technology, be specifically related to a kind of method utilizing trade waste to produce gac.
Background technology
Gac is the fuel that at home life and barbecue and metallurgy industry are conventional, although China's activated carbon industry development is comparatively rapid, but the factor long-term existence of some restriction industry developments, as serious in Activated Carbon Production environmental pollution, coal resources advantage can only be relied in a way, in the market competition of fierceness, try to achieve existence, but difficulty there is very large development.Particularly along with the pay attention to day by day of environment protection and the protection of coal resources continue to increase, the Development patterns relying on these Nonrenewable resources of coal to produce gac is more and more subject to the restriction of various factors.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of novel method utilizing trade waste to prepare gac.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is a kind of method utilizing trade waste to produce gac, be characterized in: raw material is tankage sawdust and the wood fragments head of woodenware source mill, wood fragments head is pulverized, together with sawdust, add appropriate organic binder bond, mix, use high-pressure forming machine extrusion molding, material after shaping is put into the airtight 800-900 of being heated to of stove DEG C and carries out carbonization, carbonization time 2-10 hour, after carbonization is good, cool the temperature to normal temperature.
Compared with prior art, the present invention not only takes full advantage of various trade waste, protects environment and non-renewable coal resources, and the gac indices produced all can be satisfied the demand.
Embodiment
Below further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
Embodiment 1, a kind of trade waste that utilizes is produced in the method for gac: raw materials used for waste wood and sawdust, and through adding binding agent, mixing, high-pressure molding, carbonization form.
Embodiment 2, a kind of trade waste that utilizes described in embodiment 1 is produced in the method for gac: described organic binder bond is polyacetal, and consumption is the 1-10 ‰ of raw material.
Embodiment 3, a kind of trade waste that utilizes described in embodiment 2 is produced in the method for gac: described high-pressure molding is high-pressure forming machine extrusion molding, and extruding dynamics will reach every square centimeter of 2-3 ton.
Embodiment 4, a kind of described in embodiment 2 utilizes trade waste to produce in the method for gac: described carbonization the material after shaping is put into stove is airtight to be heated to 900 DEG C and to carry out carbonization, carbonization time 6 hours.
Embodiment 5, a kind of methods experiment utilizing trade waste to produce gac: by the tankage sawdust of woodenware source mill and the pulverizing of first of wood fragments, add appropriate organic binder bond, mix, use high-pressure forming machine extrusion molding, extruding dynamics will reach every square centimeter of 2-3 ton, the material after shaping is put into stove is airtight to be heated to 900 DEG C and to carry out carbonization, carbonization time 6 hours, cools the temperature to normal temperature after carbonization is good.
