Waste water collection and recycling device for industrial metallurgy

Abstract

The invention belongs to the technical field of industrial metallurgy, and in particular, relates to a waste water collection and recycling device for industrial metallurgy. In view of the problems ofsimple design structure, insufficient energy saving and environmental protection, and low coagulation and sedimentation efficiency, provided is the waste water collection and recycling device including a sedimentation tank; a waste water pipe is inserted at one end of the outer wall of the top of the sedimentation tank; a cooling water pipe sleeves one end, away from the sedimentation tank, of the circumferential outer wall of the waste water pipe; a clamping cavity is arranged between the circumferential inner wall and the circumferential outer wall of the cooling water pipe, and both ends of the circumferential outer wall of the clamping cavity are each connected with a water pipe in an inserted manner; the middle position of the outer wall of the top of the sedimentation tank is connected with a first connecting pipe in an inserted manner, and one end, away from the sedimentation tank, of the first connecting pipe is connected with a smoke exhaust pipe by a fastening bolt. Waste water and a coagulant in the sedimentation tank are fully mixed, the coagulation sedimentation efficiency is improved, the mixture is conveyed to a water outlet pipe and a main water pipe for recyclingutilization through a water pump and a circulating water pipe, water resources is are saved, waste heat of the waste water is reused, and energy saving and environmental protection are realized.

Description

technical field [0001] The invention relates to the technical field of industrial metallurgy, in particular to a device for collecting and recycling wastewater used in industrial metallurgy. Background technique [0002] Metallurgical industry refers to the industrial sector that mines, selects and sinters metal ores, smelts them, and processes them into metal materials. It is divided into: ferrous metallurgical industry, that is, the industrial sector that produces iron, chromium, manganese and their alloys. Modern industry, transportation, infrastructure and military equipment provide raw materials; non-ferrous metallurgical industry, that is, the metal refining industry sector that produces non-ferrous metals, such as copper smelting industry, aluminum industry, lead-zinc industry, nickel-cobalt industry, tin smelting industry , precious metal industry, rare metal industry and other sectors. Metallurgical industrial wastewater refers to the wastewater discharged from the...
