Example Embodiment

[0035] Example 1

[0036] according to figure 1 Prepared as shown in Scheme Preparation VOCs adsorbing carbon, the specific method is:

[0037] 1) The desulfurization and denitrification of waste toner and waste toner Chemical Pharmaceutical carbon as a raw material, a mass ratio of 50%: 50% ratio of mixing, the primary crusher mixed into a wet ball mill to 400-600 mesh particle size.

[0038] 2) To this mixture was then added 20% Sample pre-crushed object of an adhesive 200 to obtain a mixed sample 2.

[0039] 3) The mixed sample was added 2 secondary crushing in a ball mill, stirring to 400-600 mesh. The resultant mixture continued to be added to the sample wheel rolling machine for kneading, water added to the mix several times, stirred for 2h.

[0040] 4) The material obtained in the kneading granulator exported to the hydraulic granulation, prilling into the network with a drier, and dried 80 deg.] C 2h.

[0041] 5) then dried material into the rotary type heat the carbonizat...

Abstract

The invention discloses high-performance VOCs (Volatile Organic Compounds) adsorption carbon prepared from wastes and a preparation method of the high-performance VOCs adsorption carbon, and belongs to the technical field of comprehensive utilization of waste resources. The method comprises the following steps: pretreatment of raw materials, crushing, mixing and kneading, granulation, drying, carbonization, activation, dipping, acid pickling, water washing, roasting and vibration screening and packaging. The high-performance VOCs adsorption carbon is prepared from the carbon-based solid waste and the hazardous waste, the solid waste and the hazardous waste can be effectively treated, the high-performance VOCs adsorption carbon can be prepared, VOCs in the chemical industry, the coating industry, the leather industry, the rubber industry and other industries can be efficiently purified and absorbed through the high-performance VOCs adsorption carbon, and waste resource utilization is achieved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of waste resources, and in particular relates to a high-performance VOCs adsorption carbon obtained by using waste and a preparation method thereof. Background technique [0002] There are many sources and complex types of industrial waste, and they are generally treated in a centralized and decentralized treatment system. In particular, wastes containing hazardous chemical components that have no clear use or cannot be used directly are classified as hazardous wastes for management. At present, many complex carbon-containing organic hazardous wastes produced in chemical, pharmaceutical, pesticide and other industries mostly adopt incineration disposal technology, and due to the limitation of equipment disposal capacity, it is difficult to efficiently process and utilize carbon-containing complex organic hazardous waste. It has a serious impact on production management and opera...
