Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery and utilization of waste heat boilers, in particular to a device for secondary recovery and utilization of steam from a converter waste heat boiler. Background Art

[0002] A waste heat boiler (HRB) utilizes the residual heat from exhaust gases, waste materials, or waste liquids from various industrial processes, as well as the heat generated by the combustion of combustible materials, to heat water to a specific temperature. Specifically, through a series of heat exchange processes, the waste heat from the exhaust gases, waste materials, or waste liquids is transferred to water, causing it to evaporate and produce steam or hot water for use in other industrial processes or for power generation. Existing HRBs produce a large amount of steam-water mixture during operation.

[0003] After the waste heat is recovered, condensed water will be generated. The condensed water can be incorporated into the waste heat boiler deaerator for water replenishment, thereby improving the company's energy efficiency and reducing emissions, so that the steam from the converter waste heat boiler can be recycled for a second time. The condensed water needs to be filtered before being recycled to prevent water with smoke from entering the deaerator and affecting its use. Therefore, it is necessary to propose a device for the secondary recycling of converter waste heat boiler steam. Utility Model Content
