Problems solved by technology

[0002] At present, the national environmental protection regulations are becoming increasingly stringent, and strict requirements are put forward for the emission of air pollutants. In the fields of waste incineration, hazardous waste incineration systems and iron and steel metallurgy, the quench tower is an important equipment for quenching and dust removal of high-temperature dust-laden flue gas , and the existing quench towers have certain limitations in terms of energy saving and environmental protection, and the sensible heat of the high-temperature flue gas has not been effectively utilized, resulting in a certain degree of waste, and most of the dioxins are in solid form under low temperature conditions Adsorbed on the surface of soot (mainly adsorbed on the surface of fine particles), so high-efficiency quenching and dust removal are effective means to reduce dioxins

Embodiment 1

[0018] From figure 1 It can be seen that a high-efficiency, energy-saving and environment-friendly quench tower in this embodiment includes a quench tower body 1, which is composed of a spray section 11, a waste heat recovery section 12 and a high-temperature flue gas inlet section 13, and the spray section 11 1. The inner wall of the high-temperature flue gas inlet section 13 is built with refractory materials. In order to fully ensure the waste heat recovery effect, the inner wall of the waste heat recovery section 12 is not built with refractory materials. The top of the quench tower body 1 is provided with a low-temperature gas outlet 14. There is a dust discharge outlet 15 at the bottom of the spray section 11, and a spray head 2 is arranged at an interval inside the spray section 11. The input end of the spray head 2 is externally connected to an alkaline solution through a pipeline, and the alkaline solution is selected from NaOH, KOH, Ca(OH) 2 or ammonia water, the out...

Abstract

The invention discloses a high-efficiency energy-saving environment-friendly quenching column, and belongs to the technical field of flue gas treatment. The quenching column includes a quenching column main body which consists of a spraying section, a waste heat recovery section and a high-temperature flue gas inlet section. The top of the quenching column main body is provided with a low-temperature gas outlet, and the bottom end of the main body is provided with a dust sludge discharging port. Spraying heads are arranged at intervals in the spraying section. Waste heat recovery pipes are paved on the external wall of the waste heat recovery section. The surface of the high-temperature flue gas inlet section is communicated with a venturi tube port. A flue gas treatment tube is disposed at the venturi tube port. The quenching and a chemical method are adopted to provide double security; efficient rapid cooling, dust removal, desulfurization and denitrification and dioxin removal are ensured, and heat of flue gas can be fully utilized, thus effectively saving energy, reducing energy consumption and reducing the production cost.
