Treatment device suitable for tail gas generated by household garbage cracking

Abstract

The tail gas treatment device suitable for household garbage cracking comprises an electrical tar precipitator, a carbon monoxide catalytic bed, a spray tower, a spray pump, a carbon dioxide absorption tower, a rich liquid pump, a lean and rich liquid heat exchanger, a lean liquid cooler, a regeneration tower, a reboiler, a lean liquid pump, a regenerated gas cooler, a regenerated gas separator and a reflux pump, the spray pump is connected with the spray tower to form internal circulation, the regeneration tower is connected with the carbon dioxide absorption tower through the barren liquor pump, the rich liquor pump, the barren and rich liquor heat exchanger and the barren liquor cooler, an outlet of the regeneration tower is connected with the regeneration gas cooler, an outlet of the regeneration gas cooler is connected with the regeneration gas separator, and the regeneration gas separator is connected with the regeneration tower. The regeneration gas separator is connected with the carbon dioxide absorption tower through the reflux pump, and the reboiler is communicated with the regeneration tower. Carbon dioxide in tail gas can be effectively captured and treated, and the tail gas treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a tail gas treatment device suitable for the pyrolysis of domestic garbage. Background technique [0002] At present, the tail gas generated by the domestic waste cracking furnace is generally treated by the spray tower and the activated carbon adsorption device. Among them, the exhaust gas contains atmospheric pollutants such as moisture, tar, particulate matter, carbon dioxide and carbon monoxide. Since the reduction of greenhouse gas carbon dioxide is a major problem in the current air pollution control, it has attracted great attention from the international community. [0003] At present, the treatment process of the tail gas generated by the domestic waste cracking furnace is relatively simple, and the carbon dioxide in the tail gas has not been treated, and the carbon dioxide in the tail gas cannot be effectively captured and treated. There are pr...

Problems solved by technology

[0003] At present, the tail gas treatment process produced by the domestic waste pyrolysis furnace is relatively simple, and the carbon dioxide in the tail gas has not been treated, and the carbon dioxide in the tail gas cannot be effectively captured and treated. There is no special device for carbon dioxide collection, resulting in carbon dioxide directly from Emissions in the atmosphere, resulting in low tail gas treatment efficiency, which is not conducive to environmental protection and other issues
