Combined firing method of active carbon and quicklime

Abstract

The invention relates to a combined firing method of active carbon and quicklime, which is characterized in that a firing kiln is adopted alone; raw materials used by an active carbon kiln of the firing kiln are machine-made bar materials or shells made of various plants, and the carbonization process of the bar materials is carried out by self combustion of the bar materials and the like, thereby producing carbonized material products; fumes generated by the active carbon raw materials generate high-temperature hot fumes by gas combustion, and then the high-temperature hot fumes as energy resources are supplied to a quicklime kiln; quicklime products are produced under the condition that limestone raw materials in the quicklime kiln are indirectly baked and calcined by the high-temperature hot fumes, and the fumes in the quicklime kiln are led to the active carbon kiln for use. The invention completes the carbonization process in a carbonization kiln mainly by self energy of the raw materials, and completes the curing calcining process of the limestone in a lime kiln by using the waste heat of the fumes of the carbonization kiln. The energy resource is saved and the environment is not polluted on the premise that qualified products can be produced, so that the combined continuous production can be carried out. Moreover, equipment has simple structure, low manufacture cost and low operation cost, thereby having popularization value.

Description

Technical field: [0001] The invention belongs to the technical field of firing activated carbon and quicklime, in particular to a joint firing method of activated carbon and quicklime. technical background: [0002] In actual production, although the firing of activated carbon and quicklime belong to two different technical fields, they have something in common. At least ① both require energy, the most commonly used is coal or electricity; ② both require kilns, civil engineering ③ all need to heat the raw materials, and produce products through the firing method of changing from raw to cooked; ④ whether it comes from fuel or from raw materials, there is environmental pollution. As for the difference between the two, the most obvious is that the raw materials of the two are different in nature, one comes from minerals, and the other comes from plants. In the prior art, no matter what kind of furnace type, no matter what kind of firing method, the energy consumption and pollu...
