Embodiment 1

[0030] Depend on figure 1 As shown, a powder active coke rapid preparation device includes a combustion furnace 3, an active coke preparation furnace 11, an ash collection device 1, a gas-solid separation device 12 and a powder active coke collection device 13, wherein the combustion furnace 3 is installed in The upper end of the ash collection device 1, the middle and lower parts of the active coke preparation furnace 11 communicate with the gas outlet of the combustion furnace 3, the gas-solid separation device 12 communicates with the outlet of the active coke preparation furnace 11, and the gas-solid separation device 12 The gas outlet end of the gas-solid separation device 12 communicates with the combustion furnace 3 through the combustible gas pipeline 19, and the solid outlet end of the gas-solid separation device 12 communicates with the powdered active coke collection device 13. The produced powdered active coke enters the powdered active coke collection device 13 th...

Embodiment 2

[0036] figure 2 An embodiment in which the combustion furnace 3 and the active coke preparation furnace 11 of the present invention are not coaxial is shown. In this embodiment, the combustion furnace 3 and the powdered activated coke preparation furnace 11 are not coaxial, and the two are connected by a short flue 20 . The gas-solid flow mode in the activated coke preparation furnace 11 is downstream. Raw pulverized coal is fed from the upper end of the active coke preparation furnace 11, and the raw material is evenly distributed when entering the active coke preparation furnace 11 through the pulverized coal uniform distributor 15 arranged under the pulverized coal nozzle 9. This implementation example is applicable to areas with restricted building heights, reducing the total building height. The other structures of this embodiment are the same as those of Embodiment 1.

Abstract

The invention relates to a device and method for rapidly preparing powdered activated coke, comprising a combustion furnace, an activated coke preparation furnace, an ash and slag collection device, a gas-solid separation device and a powdered activated coke collection device, wherein the combustion furnace is installed in the ash and slag collection device. At the upper end of the device, the middle and lower parts of the activated coke preparation furnace communicate with the gas outlet of the combustion furnace, the gas-solid separation device communicates with the outlet of the activated coke preparation furnace, and the gas outlet end of the gas-solid separation device communicates with the combustion furnace, The solid outlet end of the gas-solid separation device communicates with the powder activated coke collecting device. Since the activated coke preparation device of the present invention is provided with a burner, the system is independent, and the heat source and gas self-sufficiency can be realized; The arrangement of complicated high-temperature pipelines is reduced; the structure of the invention is compact, the floor area is small, and the investment in infrastructure construction is low.

Description

technical field [0001] The invention specifically relates to a device and method for rapid preparation of powdered active coke. Background technique [0002] Calcium-based wet desulfurization technology is mostly used in my country's flue gas desulfurization technology. Desulfurized gypsum, a by-product of calcium-based wet desulfurization, can be used in the construction industry. However, due to the excess production of construction gypsum in my country, the application of desulfurized gypsum is difficult. my country is a country that is relatively short of sulfur resources, so the adoption of technologies that can realize the recovery of sulfur resources can solve the current situation of the lack of sulfur resources in my country. [0003] Activated coke dry flue gas desulfurization technology is an effective technology for sulfur dioxide removal and green resource utilization. This technology has high desulfurization efficiency, can realize sulfur resource recovery, and...
