Abstract

The invention discloses a cooling system for ADA desulfurization and salt extraction in non-blast furnace iron-making. The cooling system comprises a bottom plate, the left side of the top of the bottom plate is fixedly connected with a cooling bin, an operation furnace is placed in the inner cavity of the cooling bin, the right side of the top of the bottom plate is fixedly connected with a waterstorage bin, the top of the water storage bin is fixedly connected with a second water pump, and the right side of the second water pump communicates with a third connecting pipe. Through the bottomplate, the cooling bin, a vertical pipe, a fan, a first water pump, the water storage bin, the second water pump, a heat dissipation frame, an annular water pipe, an atomizing nozzle, a connecting andfixing steel pipe, an annular copper pipe and a heat dissipation grid, the cooling system has a good energy saving effect, the problems that an existing cooling device for desulfurization and salt extraction in the market does not have a good energy saving effect, the energy waste in the cooling process is serious, the cooling liquid cannot be recycled, and the production cost is greatly improvedare solved; and sustainable utilization of energy is realized.

Description

technical field [0001] The invention relates to the technical field of ironmaking, in particular to a cooling system for ADA desulfurization and salt extraction for non-blast furnace ironmaking. Background technique [0002] In the non-blast furnace ironmaking process, by-product gas with a certain calorific value is associated with it. The sulfur content of the flue gas after burning by-product gas is about 2000mg / Nm3, and flue gas desulfurization must be carried out after discharge. Currently, ADA desulfurization is used for flue gas desulfurization. craft. In the process of ADA desulfurization and salt extraction, the working furnace needs to be cooled to extract salt. The existing cooling devices for desulfurization and salt extraction on the market have high energy consumption and low cooling liquid circulation ratio. The purpose of the present invention is to develop a simple structure, high efficiency Cooling system for desulfurization and salt extraction. Contents...
