Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] The features of the present invention will be explained more clearly with reference to the following examples. However, the examples should not be considered as limiting the scope of the invention.

[0039] It can be seen from the drawings that the device of the present invention is composed of two feeding mechanisms A, two clean gas outlets B, two pre-purification chambers C, a movable adsorption bed D and a discharging mechanism E. The feeding mechanism A is composed of a feeding hopper a1, a feeding lock valve a2 and a feeding pipe a3. The discharge mechanism E is composed of a discharge cone e1, a blanking air lock valve e2 and a material guide pipe e3. Three adsorption sections d1, d2, and d3 with the same cuboid structure are sequentially stacked in the height direction to form a mobile adsorption bed D. The top center of the adsorption s...

Abstract

The present invention provides coupling multistage apparatus with active carbon to purify waste gas, and the apparatus is used in desulfurizing, denitrating, dedusting, eliminating heavy metal and eliminating organic compound of waste gas. It consists of pre-purifying room, movable adsorption bed, purified gas outlet, material feeding mechanism, and discharging mechanism. Each of the material feeding mechanism and the discharging mechanism consists of material bin, material guide pipe and gas trap valve. The movable adsorption bed consists of one or several adsorption sections superposed sequentially, the material feeding mechanism is set on the top, the discharging mechanism is set in the bottom, and the pre-purifying room and the purified gas outlet are set in the side. The apparatus has compact structure, simple material distribution, complete functions, less resistance, high purifying effect, fully use of active carbon, long service life and low running cost.

Description

technical field [0001] The invention relates to a method for using activated carbon to target the harmful substance SO in exhaust gas 2 , NOx, dust, heavy metals (such as mercury, arsenic, etc.) and organic compounds (such as dioxin, etc.) for multi-directional purification of integrated coupling, multi-stage purification device, which belongs to the technical field of waste gas purification environmental protection equipment and chemical equipment manufacturing. Background technique [0002] There are many harmful substances in industrial waste gas, such as SO 2 , NOx, dust, mercury, arsenic and other heavy metals and organic compounds such as dioxins, which need to be purified and then emptied so as not to pollute the atmospheric environment. Therefore, a variety of single-purpose or multi-purpose purification equipment is required. [0003] The moving bed dry desulfurization and denitrification technology, which uses activated carbon as a desulfurization adsorbent and s...
