Problems solved by technology

Although this type of process has a good reduction effect on VOCs, it consumes a lot of energy and emits a lot of carbon during the purification process; these hydrocarbons are directly burned to directly convert organic matter into CO 2 , will cause serious waste of resources, economic losses and environmental pollution

Embodiment 1

[0036] according to figure 1 The preparation process shown in the preparation of VOCs adsorption carbon, the specific method is:

[0037] 1) Use desulfurization and denitrification waste carbon powder and chemical and pharmaceutical waste powder carbon as raw materials, mix according to the mass ratio of 50%:50%, enter the wet ball mill after mixing, and crush it to a particle size of 400-600 mesh.

[0038] 2) Then add 20% of pre-crushed binder to 200 mesh into the mixed sample to obtain mixed sample 2.

[0039] 3) Put the mixed sample 2 into a ball mill for secondary crushing, and stir to 400-600 mesh. Continue to add the obtained mixed sample into the wheel roller compactor for kneading, add water to the mixed material several times, and stir for 2 hours.

[0040] 4) The obtained kneaded material is exported to a hydraulic granulator for granulation, and the granulated material enters a mesh belt dryer and is dried at 80° C. for 2 hours.

[0041] 5) Then the dried materia...

Embodiment 2

[0047] 1) The blue charcoal powder and chemical and pharmaceutical waste powder charcoal are used as raw materials, mixed according to the mass ratio of 40%:60%, and then entered into a wet ball mill for primary crushing to a particle size of 400-600 mesh.

[0048] 2) Then add 20% of pre-crushed binder to 200 mesh into the mixed sample to obtain mixed sample 2.

[0049] 3) Put the mixed sample 2 into a ball mill for secondary crushing, and stir to 400-600 mesh. Continue to add the obtained mixed sample into the wheel roller compactor for kneading, add water to the mixed material several times, and stir for 2 hours.

[0050] 4) The obtained kneaded material is exported to a hydraulic granulator for granulation, and the granulated material enters a mesh belt dryer and is dried at 80° C. for 2 hours.

[0051] 5) Then the dried material enters the internal heating type rotary carbonization furnace for the carbonization process. The carbonization temperature is 700-900° C. and the...

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...
