Abstract

The invention relates to the field of high polymer and particularly relates to an air circulation carbon granule for an air conditioner. The carbon granule is produced through the following steps of pre-treating raw materials: feeding the plant raw materials to a microwave vacuum tank, and performing vacuumizing and microwave treatment; sequentially subjecting the raw materials to drying, pre-carbonizing, carbonizing, calcining and cooling, controlling burning and heating the raw materials to 700-750 DEG C or 900-1000 DEG C at the rate of 5-15 DEG C/min, preserving heat for 40-80 minutes, then heating the raw materials to 1000-1500 DEG C or 1600-1800 DEG C at the rate of 5-15 DEG C/min, preserving heat for 2-8 hours, cooling burning to 300-400 DEG C at the rate of 18-25 DEG C/min, and performing cooling with a furnace to room temperatures to obtain primary carbon; performing soaking treatment: soaking the primary carbon in a solution with the acid content of 3-5wt.% for 20-40 minutes, then performing vacuum pressurizing flame retardant treatment, performing vacuumizing to enable the vacuum degrees to be -0.015 MPa--0.025 MPa, adding a fire retardant to the tank and then performing pressurizing to enable the pressure to be 0.1 MPa-0.8 MPa; performing microwave treatment; and preparing the carbon granule. The prepared carbon granule is free of dust and impurities and good in antistatic property and has an inflaming retarding function.

Description

technical field [0001] The invention relates to the field of polymers, in particular to a carbon particle for air conditioning air circulation. Background technique [0002] At present, the methods for firing wood charcoal materials include a one-time carbonization firing method and a graded temperature-controlled firing method. [0003] The secondary carbonization firing method is a method in which the incompletely carbonized wood charcoal is sintered at a high temperature to prepare a conductive wood charcoal material. For example, Japanese patent JP 2005035806 conductive charcoal or bamboo charcoal and its preparation method is a method for preparing conductive charcoal or bamboo charcoal by carbonizing block charcoal or bamboo charcoal at a temperature above 1000°C once. The carbon yield of this preparation method is high, but the sintering process requires a second temperature rise for sintering, and the carbon oxidation is likely to occur during the second sintering p...
