An active coke adsorption device

Abstract

The present invention discloses an activated coke adsorption device which comprises a shell, the shell is connected with an air inlet and an air outlet, the shell is internally provided with a plurality of carbon layers, the direction of the air inlet is located in the front side of the carbon layers, the air outlet is located in the rear side of the carbon layers, clapboards are arranged between the plurality of carbon layers, an airtight space is formed between adjacent clapboards, a plurality of ventilation pipelines are arranged in the clapboards in the pass-through manner, the ventilation pipelines are respectively connected with the front sides of the carbon layers of the airtight space, air passages communicated with the air outlet are all arranged in the rear sides of the carbon layers. By use of the structure, the problem of too large resistance caused by an air flow simultaneously passing through the multilayer carbon layers can be well solved, the carbon layer adsorption spared quantity is same, and during maintenance, the multilayer carbon layers can be replaced simultaneously, and maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of industrial tail gas purification, in particular to an activated coke adsorption device. Background technique [0002] Existing technologies and their shortcomings: incineration, as a harmless, volume-reducing, and recyclable waste treatment technology, has become an important disposal technology for waste treatment in the international community today; however, the composition of incineration flue gas is extremely complex, and the main pollutants are Heavy metals and dioxins, etc.; with the continuous improvement of my country's environmental protection requirements, strict restrictions have been imposed on the emission standards of waste incineration flue gas, and some indicators have reached the European EU2000 / 76 / EC standard, so that reasonable and effective flue gas treatment Technology is a necessary condition to ensure the promotion and implementation of waste incineration. [0003] The conventional ...

[0002] Existing technologies and their shortcomings: incineration, as a harmless, volume-reducing, and recyclable waste treatment technology, has become an important disposal technology for waste treatment in the international community today; however, the composition of incineration flue gas is extremely complex, and the main pollutants are Heavy metals and dioxins, etc.; with the continuous improvement of my country's environmental protection requirements, strict restrictions have been imposed on the emission standards of waste incineration flue gas, and some indicators have reached the European EU2000 / 76 / EC standard, so that reasonable and effective flue gas treatment Technology is a necessary condition to ensure the promotion and implementation of waste incineration

However, it is not easy to switch the adsorption device from the entire flue gas treatment system; in order to ensure the flow rate of the flue gas in the carbon layer and reduce the pressure drop, the carbon layer should not be too thick, which means that the carbon layer needs to reach a certain flow area, that is, a single layer The adsorption device often occupies too much area; and due to the complexity of the incineration tail gas, the activated carbon layer is easy to block; the loading and unloading of activated carbon is also a big problem, which affects the maintenance of the adsorption device

[0004] At the same time, it is not easy to switch out the traditional adsorption device from the whole set of flue gas treatment system; the conventional adsorption device is large in size and occupies a large area; the adsorption material is easy to block, and needs to be loaded and unloaded regularly, or regenerated and recycled. Maintenance of adsorption unit
