Summary of the invention
In order to overcome the deficiency of existing flue gas quenching apparatus, the secondary that the utility model provides a kind of flue gas quenching apparatus can effectively prevent dioxin from the flue gas that various incinerators, smelting furnace etc. are discharged is synthetic.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of flue gas quenching apparatus, has the rapidly cooling tube body, rapidly cooling tube body one end is provided with the high-temperature gas inlet, the other end is provided with gas vent, the rapidly cooling tube body is divided into two sections, be set side by side with at least two coiled pipes in first section rapidly cooling tube body, has cooling medium in the coiled pipe, be set side by side with at least two straight tubes in second section rapidly cooling tube body, has cooling medium in the straight tube, first section rapidly cooling tube body is provided with the introducing port and the export mouth of the cooling medium that links to each other with coiled pipe, and second section rapidly cooling tube body is provided with the introducing port and the export mouth of the cooling medium that links to each other with straight tube.
Further: the cooling medium in the described coiled pipe is conduction oil or steam.
Further: the cooling medium in the described straight tube is a water.
Cooling medium conduction oil or the steam of the high-temperature gas more than 850 ℃ that dioxin is in decomposing state in the coiled pipe of first section of airtight rapidly cooling tube body and rapidly cooling tube body carries out heat exchange, cooling significantly, again through second section rapidly cooling tube body, the heat exchange of carrying out with cooling medium water in the straight tube in the rapidly cooling tube body, further cooling, and flow out the rapidly cooling tube body with the short time, within 1 second, be cooled to dioxin again below the synthesis temperature to guarantee the high-temperature gas more than 850 ℃ that dioxin is in decomposing state.
The beneficial effects of the utility model are, flue gas quenching apparatus of the present utility model is simple in structure, can prevent effectively that the secondary of dioxin from the flue gas that various incinerators, smelting furnace etc. are discharged is synthetic, and cost is low, and heat energy can fully utilize.
