High-temperature steam afterheat recycling device based on lead paste smelting

Abstract

The invention discloses a high-temperature steam afterheat recycling device based on lead paste smelting. The device comprises a cooling water storage box; the lower part of the right side of the cooling water storage box is connected with a cooling water inlet pipe and a cooling circulating water pipe; the cooling water inlet pipe is connected with water cooling equipment of an air blowing furnace used in the lead paste smelting process; and cooling water in the water cooling equipment of the air blowing furnace enters a cooling water storage box through the cooling water inlet pipe, and is stored in the cooling water storage box. A hot water tank can exchange heat of water in a cooling water circulating tank and a heat exchange water tank through a sunk coiled pipe heat exchanger, so that the cooling water can reach a heating temperature for direct use; meanwhile, the water in the heat exchange tank after heat exchange has a certain heat, so that the utilization of the heat in the cooling water is realized; and the water in the heat exchange tank can be directly used for heating when reaching the heating temperature, and can flow back into the cooling water storage box when the temperature is lower for repeated cooling of hot air in the air blowing furnace.

Description

technical field [0001] The invention belongs to the fields of energy-saving technology and waste heat heating, and relates to a high-temperature steam waste heat recovery device based on lead paste smelting. Background technique [0002] In recent years, with the increasing scarcity of lead concentrate resources, the difficulty of procurement has increased, and the cost of mineral lead processing may continue to rise, which can no longer meet the needs of enterprise development. At the same time, with the continuous development of my country's automobile industry and electric vehicle industry, millions of tons of waste lead-acid batteries are produced every year, and waste lead-acid batteries have become a huge recyclable renewable resource. With the production of lead paste smelting, a large amount of waste heat such as waste steam, waste hot water, and waste flue gas is often discharged. These waste heat discharges not only waste energy, but also cause thermal pollution to...
