Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0026] refer to figure 1 , the blast furnace cooling circulation system, comprising a water storage tank 2, the bottom of the water storage tank 2 communicates with the water inlet end of the furnace wall cooling pipe network of the blast furnace 1 through the blast furnace water inlet pipe 11, and the top of the water storage tank 2 passes through the blast furnace outlet pipe 12 communicates with the outlet end of the furnace wall cooling pipe network of the blast furnace 1. The water in the water storage tank 2 enters the furnace wall cooling pipe network of the blast furnace 1 through the blast furnace inlet pipe 11 to cool the furnace wall, and then becomes wate...

Abstract

The invention discloses a blast furnace cooling circulation system which comprises a water storage cylinder, the bottom of the water storage cylinder is communicated with the water inlet end of a furnace wall cooling pipe network of a blast furnace through a blast furnace water inlet pipe, and the top of the water storage cylinder is communicated with the water outlet end of the furnace wall cooling pipe network of the blast furnace through a blast furnace water outlet pipe. New cold water is supplied to the water storage tank in the self-circulation process of the evaporative cooling system, the cooling capacity of the evaporative cooling system is improved, meanwhile, the water storage tank is provided with the power-off water supply assembly, the power-off water supply assembly uses water vapor circulation energy generated by heat of the blast furnace to complete continuous water feeding of the water storage tank under the power-off condition, and the water supply efficiency is improved. Therefore, continuous operation of the whole cooling circulation system is kept, the cooling effect of the blast furnace is kept, and energy recycling is achieved.

Description

technical field [0001] The invention relates to the technical field of metal processing equipment, in particular to a blast furnace cooling circulation system. Background technique [0002] In the field of non-ferrous metal smelting, the blast furnace has a long history as a pyrometallurgical smelting equipment. Compared with the electric furnace and the rotary furnace, the blast furnace is simple in operation, high in thermal efficiency, small in investment, low in operating cost, and high in unit production capacity. The recovery rate is high, so the use of blast furnaces to extract heavy metals has become the best choice for many enterprises in our country. [0003] The normal operation of the blast furnace is inseparable from cooling. The vaporization cooling system is often used to cool the blast furnace wall. The cooling water can take away the heat from the blast furnace and reduce the temperature of the lining, which not only ensures the integrity of the lining, but ...
