The water slag flushing process is adopted in front of the fuming furnace, so that the slag discharge of the blast furnace on time can be ensured, the total length of a slag runner can be shortened, and the slag is not limited by a slag pot, thereby being beneficial to the discharge of clean slag iron. The currently used slag flushing water tank is provided with a water tank which is directly connected with a slag flushing return water pipe, raw slag flushing return water directly enters an inlet water tank of a slag flushing pump through a water flow channel after the overflow quantity is regulated through a gate valve, and slag slurry is sucked into slag flushing water in front of a furnace by a slag slurry pump and then enters the water tank through a return water pipeline, so that the cyclic utilization of the slag flushing water is realized. However, as the slag water tank of the fuming furnace has larger slag feeding quantity and no precipitation structure in the process, so that the water slag is not precipitated enough, a large amount of water slag is mixed in the slag water, so that the slag slurry pump is frequently damaged, the maintenance cost is high, the slag system frequently fails, the slag water pipeline is worn by the slag water with a large amount of water slag entrained, so that the operation rate of the fuming furnace is low, and meanwhile, the slag water quantity is not enough, so that slag explosion can be caused, and great potential safety hazards are brought to slag discharging operators and slag dewatering system equipment.

Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.
A water flow channel 9 is arranged on the right side of a water tank 11 at the inlet of the slag flushing pump, a water tank two 3 and a water tank one 2 are arranged on the right side of the water flow channel 9 from top to bottom, the water tank one 2 and the water tank two 3 are communicated with the water flow channel 9, but the water tank one 2 and the water flow channel 9 are blocked through a gate valve 6 in order to prolong the residence time of slag flushing water in the water tank. The right side of the first water tank 2 is communicated with the outlet of the slag flushing water return pipe 1, a first partition wall 4 is installed in the middle of the first water tank 2 and provided with an overflow port 5, the first partition wall 4 is manufactured by using an original fuming furnace waste water jacket, the height of the first partition wall is 3.5 meters, the length of the overflow port 5 is 1.5 meters, the depth of the overflow port is 1 meter, the circulation requirement of slag flushing water quantity is met, the partition wall utilizes the principle that water slag is heavier than water to keep off slag at the lower part of the partition wall, slag flushing water flows into the front end of the first water tank 2 through the overflow port 5, and primary precipitation is achieved. The front ends of the walls of the first water tank 2 and the second water tank 3 are provided with a communication port 7, the communication port 7 is positioned at the position of the wall 2.5 m, the height is 1 m, the width is 1.5 m, the first water tank 2 and the second water tank 3 are connected in series, the residence time of slag flushing water in the water tank is prolonged, and secondary precipitation is realized. The second partition wall 8 is additionally arranged on the waste water jacket of the primary fuming furnace in the second water tank 3, the second partition wall 8 is of an L-shaped structure, slag flushing water flows out from the partition of the L-shaped partition wall and the second water tank 3, the water speed is further reduced, the water yield speed is reduced, the further precipitation of water slag is facilitated, and the three-level precipitation is realized. The front end of the second water tank 3 is communicated with the water flow channel 9, and slag flushing water realizes four-stage precipitation in the process of flowing in the rear side of the second water tank 3, and the amount of water slag entering the slag flushing pump inlet water tank 11 is greatly reduced by the four-stage precipitation. A filtering grid 10 is arranged at the communication part of the second water tank 3 and the water flow channel 9, and the filtering grid 10 filters floaters such as wood, plastic bottles and the like, so that the floaters are prevented from entering the inlet water tank 11 of the slag flushing pump to be sucked into the pump, and equipment is prevented from being damaged. When the first water tank 2 and the second water tank 3 flow, the flow speed is reduced, the slag is blocked at the lower part of the partition wall by the partition wall after the flow speed is reduced by using the specific water weight of the water slag, the water finally flows into the water tank of the inlet pipe of the slag flushing pump through the overflow port 5, and the stopped water slag is periodically cleaned by the water slag crane. The slag flushing pump inlet water tank 11 is provided with three slag flushing pump water inlets 12, slag flushing operation is carried out before the furnace respectively after slag flushing pump sucks slag flushing water, and the slag flushing water enters the water tank again through the slag flushing return pipe 1 for precipitation and filtration after the operation is finished, so that the circulation operation is realized.
