Embodiment 1

[0034] Such as figure 1 As shown, the fanless smelting blast furnace supply oxygen-enriched air and air separation energy-saving and power-saving system includes a mixed gas regulator 1, an air buffer tank group, a mixed gas regulator 2 and air separation equipment.

[0035]The air separation plant includes an air compression system, a precooling system, a purification system and a fractionation tower system. The air input to the air separation unit is sequentially processed by the air compression system, precooling system, purification system and fractionation tower system, and then the oxygen is output respectively. and nitrogen to achieve air separation. The specific structure and specific working process of the air separation plant belong to the prior art and will not be repeated here.

[0036] The mixed gas regulator 1 includes a conventional air input port and a high-pressure air input port, wherein the conventional air input port refers to a general normal-pressure cle...

Embodiment 2

[0045] The difference between this embodiment and the foregoing embodiments is that the oxygen supply system in this embodiment has only one mixed gas regulator, such as image 3 As shown, the output end of the gas heat exchanger is connected to one input end of the mixed gas regulator through a pipeline; the oxygen output port in the fractionation tower system is connected to the other input end of the mixed gas regulator through a pipeline, and the mixed gas regulator The output terminal outputs the required air to the blast furnace or the oxygen-enriched air storage tank group. The oxygen supply system does not have the effect of "diluting" the vaporized air, and can only adjust the oxygen content.

[0046] In addition, the oxygen supply system provided by the present invention is not limited to the above two embodiments, and the oxygen supply system may not be provided with a mixed gas regulator, as long as the liquid air tank in the fractionation tower system is connected...

Abstract

The invention relates to a system for supplying oxygen-enriched air and air separation for energy-saving and power-saving of a fanless smelting blast furnace, including an air separation system, which includes a fractionation tower system, etc. Gas vaporization heat exchanger, the liquid air tank in the fractionation tower system is connected to the input end of the gas heat exchanger through pipelines, and the output end of the gas heat exchanger outputs the required vaporization air. First, the liquid air in the lower tower of the air separation fractionation tower system passes through the gasification heat exchanger to form gasification air, and the gasification air is sent to the smelting blast furnace for smelting production. The oxygen-enriched air supply system replaces the original oxygen-enriched air blower for the smelting blast furnace, eliminates the power consumption of the smelting blast furnace blower and the investment cost of the blast furnace blower, reduces the production cost of the smelting factory, and greatly saves energy. The implementation of the invention will produce huge economic benefits, environmental benefits and social benefits.

Description

technical field [0001] The invention relates to a fanless smelting blast furnace energy-saving and electricity-saving system for supplying oxygen-enriched air and air separation, which belongs to the fields of smelting and chemical industry. Background technique [0002] Technical background of air separation plant: [0003] This paper reviews the development process of my country's large and medium-sized air separation process technology in the past fifty years, comments on the seven reforms of the survival of the fittest in the air separation process, and clarifies that the goal of realizing the reform of the large and medium-sized air separation process in my country should be to further improve the unit equipment department. Machine technology level, control level energy saving and intelligent large-scale internal compression process. [0004] Every change in the large and medium-sized air separation process is the inevitable result of the continuous development of air s...
