Abstract

The application discloses a cooling method for a distributor, which includes the following steps: passing nitrogen and cooling water into the annular tank from the top of the box; nitrogen passing into the annular tank from both sides of the fixed separator; cooling water passing through Enter the annular tank through the fixed separator, and return to the annular tank through the cooling water pipe; when the liquid level of the cooling water is higher than the water outlet on the fixed separator, adjust the pressure of nitrogen and cooling water; the fixed separator The cooling water and nitrogen on both sides form a state of dynamic equilibrium; the cooling water is discharged from the top of the box through the fixed separator; the cooling liquid exchanges heat with the rotating cylinder when it circulates in the annular tank and the cooling water pipe, and the rotating cylinder The cylinder is cooled, and the nitrogen in the annular tank and the blast furnace gas in the rotating cylinder are sealed by the rotating sealing ring. The application solves the problems of poor sealing performance and poor cooling effect of the distributor in the prior art, and can provide a relatively large flow of cooling water, thereby improving the cooling effect and ensuring the smelting effect.

Description

technical field [0001] The application belongs to the technical field of distributors, and in particular relates to a cooling method of distributors. Background technique [0002] As shown in Figure 1, the distributor is installed on the upper part of the steel ring of the blast furnace roof and is the core component of the blast furnace roof. The distributor includes a box body 101 , a rotating cylinder 102 , an upper water tank 103 and a lower water tank 104 arranged in the box body 101 . The box body 101 is connected with the water tank 104 as a whole to form a fixed body, and the lower end of the fixed body is installed on the furnace roof steel ring. The rotating cylinder 102 is connected with the upper water tank 103 as a whole to form a rotating body. The rotating body is connected with the distribution chute through a gear train, and the gear train drives the distribution chute to rotate, and then distributes materials to the blast furnace. A labyrinth sealing str...
