Abstract

PURPOSE:To obtain active carbonized coal having a large amount of adsorption of dirt and highly cleaning effects, by carbonizing brown coal or low-quality coal, washing the coal with an acid and forming numberless fine pores in the interior of the surface. CONSTITUTION:Brown coal or low-quality coal having about 5-25 mm is closed in a non-contact state with air, heated from the exterior at low temperature <=450 deg.C, thermally decomposed and heated once or plural times until the closed coal becomes porous. Then the closed coal is cooled, washed with an inorganic acid, activated, numberless fine pores are formed to give the objective active carbonized coal. Dirty water is passed through the carbonized coal when the active carbonized coal is scattered as a filter medium and dirt is adsorbed to clean the dirty water.

[Conventional technology] Petroleum-based filth from seawater is adsorbed using fine charcoal, which has fine pores formed on the surface and inside of the coal, which is made from low-grade coal with a particle size of 160 to 200 mesh and whose ash content has been reduced for conventional purification. There is something that makes it so.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention has five features to solve the problems.
~25 mm of lignite or low-rank coal is hermetically sealed and dry-distilled at a low temperature below 450℃ until it becomes porous, then pickled with inorganic acids to activate it, and the activated dry-distilled coal, which has formed countless pores, is scattered to remove filth. It is provided for the purpose of effective purification by adsorption.

[Function] When activated dry distilled carbon of about 5 to 25 mm is sprinkled on the surface of a river as a filter medium, sewage comes into contact with the dry distilled coal and flows through the pores.
During this time, the dirt flowing with the water is absorbed and purified.

[Example] The present invention involves sealing lignite, low-grade coal, etc. of about 5 to 25 mm in a container, cutting off contact with air, and exposing it to 450 mm from the outside.
It decomposes by heating at a low temperature below ℃, then it is heated at a low temperature once or multiple times until the contents become porous, and after cooling, it is pickled with inorganic acids in a pickling tank, forming countless pores. . It also becomes activated and exhibits ion exchange resin properties.

[Effects] As mentioned above, in the present invention, lignite or low-grade coal of about 5 to 25 mm is sealed to prevent contact with air, and heated from the outside at a low temperature of 450"C or less to thermally decompose it. This sealed charcoal is heated once or multiple times until it becomes porous,
This method is used to produce activated dry-distilled charcoal, which is cooled and then pickled with inorganic acids to form countless pores. By pickling, the contact surface becomes very large and is further activated, which allows a large amount of dirt to be adsorbed and a good purification effect.
