Waste water recovery device for blast furnace cleaning and use method thereof

Abstract

The invention discloses a waste water recovery device for blast furnace cleaning and a using method thereof. The waste water recovery device comprises a recovery box, a storage box is fixedly connected to one end of the top of the recovery box, a filling pipe is fixedly connected to the top of the storage box, a first through hole is formed in one end of the bottom of the storage box, and an electromagnetic valve is fixedly installed in the first through hole; a first through hole is formed in the top of the temporary storage barrel, a second through hole is formed in the position, located under the first through hole, of the top of the recycling box, and a rotating sleeve is rotationally connected to the top of the inner wall of the recycling box. The device is compact in structure, easy and convenient to operate and high in practicability; the driving mechanism is arranged to drive the temporary storage cylinder with the through hole to revolve, and is matched with the disc which can revolve and rotate at the same time and is provided with the through holes; when the through holes are matched, the uniform feeding operation of the flocculant is completed, and the device is matched with the stirring blades to stir wastewater, so the wastewater treatment effect is greatly improved, and actual application and operation are facilitated.

Description

technical field [0001] The invention belongs to the technical field of waste water recovery, and in particular relates to a waste water recovery device for blast furnace cleaning and a use method thereof. Background technique [0002] In the existing life, the blast furnace uses steel plates as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: the furnace throat, the furnace body, the furnace waist, the furnace bosh, and the hearth. The technical and economic indicators are good, the process is simple, the production volume is large, the labor production efficiency is high, and the energy consumption is low. Flux for rock, coke, and slagging, blowing preheated air from the tuyeres located at the lower part of the furnace along the periphery of the furnace, carbon monoxide and hydrogen generated by burning the carbon in the coke with the oxygen blown into the air at high temperature, in the ...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing waste water recovery devices for cleaning blast furnaces directly put flocculant into the waste water, and then perform solid-liquid separation on the waste water after it is completely precipitated, and recycle the supernatant, but there is a lack of flocculant injection inside the device. mechanism, resulting in insufficient uniformity of flocculant injection, resulting in insufficient sedimentation, resulting in poor treatment effect, which is not conducive to practical application
