Active coke smoke purifying device for optimizing air-flow distribution

Abstract

The invention provides an active coke smoke purifying device for optimizing air-flow distribution. The active coke smoke purifying device comprises a plurality of ranks of active coke absorbing layers; the upper ends and the lower ends of the active coke absorbing layers in each rank are respectively communicated with material inlet storage bins and material outlet bins; unloading devices are arranged at the lower ends of the active coke absorbing layers in each rank; the first rank of active coke absorbing layers has the structure that windward end surface air-flow distributing plates are arranged on the outer sides of the active coke absorbing layers on the windward end surfaces; intermediate air-flow distributing plates are arranged among the active coke absorbing layers in each rank; and the vertical section surface of each intermediate air-flow disturbing plate has the aperture ratio under a structure which is wide in upper part and narrow in lower part. According to the active coke smoke purifying device, the active coke is separated into the plurality of ranks by the air-flow distributing plates; the saturated and unsaturated active cokes have different movement speeds, so that the discharge rate and the circulation volume of the active cokes are low; the air-flow distributing plates performs optimization to the air flow, and the smoke and the active coke are subjected to a movement mode in combination of stagger flowing and opposite flowing, so that the air-flow distribution in the purifying device is in matched with the absorbing capacity of the active coke, high purifying efficiency is brought to a system, and the resistance of the smoke is low.

Description

technical field [0001] The invention relates to equipment for purifying and treating flue gas pollutants in an active coke dry process, in particular to an active coke flue gas purifying device for optimizing airflow distribution. Background technique [0002] Activated coke flue gas purification technology can treat various pollutants SO in flue gas 2 , SO 3 , NOx, HCl, HF, dust, heavy metals, dioxins, etc. are simultaneously removed, and the removal efficiency is high, which can meet very strict environmental protection standards; and it is a dry flue gas purification technology, and the water consumption is only equivalent to that of the wet method 1 / 10 of desulfurization; there are no problems such as chimney anticorrosion, "gypsum rain" and net flue gas droplet carrying in wet flue gas desulfurization; sulfur resources in flue gas can also be recovered, and by-products can be used as resources. Therefore, the performance index of activated coke flue gas purification t...

AI Technical Summary

Problems solved by technology

However, the structure of the convective flue gas purification device is complicated. The active coke outlet and the flue gas inlet are all set at the bottom of the purification device, and the active coke feed port and the flue gas outlet are both set at the top of the purification device, and there are many active coke Slide pipe, equipment manufacturing and processing are difficult, the risk of device failure is high, and the equipment occupies a large area, and the system resistance is high

[0006] At present, among the active coke flue gas purification devices used abroad, the cross-flow type is the main one, but the above problems of the cross-flow type have not been effectively solved
