Problems solved by technology

With the shortage of fresh water resources, iron and steel enterprises have begun to develop non-traditional water resources. Coastal iron and steel enterprises have gradually replaced surface water with seawater desalination water, which can make full use of the excess energy and heat resources of iron and steel enterprises to achieve seawater desalination. Low resource utilization and high energy consumption

Abstract

The invention provides a high-efficiency seawater distillation desalination device for steel production, which includes a water tank, a residual heat recovery system, a distillation apparatus, a concentrated salt water storage tank, and a cooling tank. The residual heat recovery system includes an oil tank and a heat absorption coil arranged on a boiler. The distillation apparatus is provided witha heating apparatus, is connected to the concentrated salt water storage tank through a concentrated salt water discharge pipe, and is connected to the cooling tank through a vapor pipeline. The device has simple structure and reasonable design; by fully utilizing residual heat from the boiler, the seawater is desalinated into desalted water with residual heat, wherein the desalted water can be applied to all sections in steel production. An electronic balance can control distillation quantity. Heating coils have a snakelike shape and are respectively formed in aluminum or copper heating block in a casting manner, so that the heating block is high in heat absorption speed and heat absorption efficiency. The distillation apparatus is high in distillation efficiency. The heating block is arranged in a box, so that heat can be absorbed by water in the box, thereby reaching a low heat loss rate.

Description

technical field [0001] The invention relates to the technical field of steel production, in particular to a high-efficiency distillation seawater desalination device applied to steel production. Background technique [0002] The iron and steel industry is a major energy consumer. The energy consumption of my country's iron and steel industry accounts for about 27% of the total industrial energy consumption in the country. With the emergence of energy shortages and environmental pollution problems, the utilization efficiency of waste energy and waste heat in iron and steel enterprises has gradually improved. With the shortage of fresh water resources, iron and steel enterprises have begun to develop non-traditional water resources. Coastal iron and steel enterprises have gradually replaced surface water with seawater desalination water, which can make full use of the excess energy and heat resources of iron and steel enterprises to achieve seawater desalination. The resource ...
