High-efficiency heat recovery unit for temperature wastewater

Abstract

The invention belongs to the field of waste heat recovery devices, and relates to a device for recovering waste heat of living hot water and production hot water such as water in swimming pools, bathing water and water for factories, in particular to a high-efficiency heat recovery unit for waste hot water. The high-efficiency heat recovery unit for waste hot water comprises a waste water processing device, a first-stage heat recovery device and a second-stage heat recovery device. Through the waste water processing device, the first-stage heat recovery device and the second-stage heat recovery device, the waste heat utilization efficiency can be greatly improved, cost can be greatly reduced for residents, factories, hospitals, schools, bathing, business and other places needing hot water, and the pressure of energy shortage in China is relieved. In addition, the high-efficiency heat recovery unit for waste hot water is applicable to large-scale production and convenient to operate.

Description

technical field [0001] The invention belongs to the field of waste heat recovery devices, and relates to a device for recovering waste heat by using hot water in life and production such as swimming pools, baths and factories, and in particular to a high-efficiency heat recovery unit for temperature wastewater. Background technique [0002] With the development of society, all walks of life must start from themselves if they want to survive in this severe society, such as reducing energy consumption, saving costs, and technological innovation. However, in the production process of dyeing and finishing, washing water, papermaking, chemical industry, bathing and other industries, a large amount of waste hot water will be discharged. The temperature of these waste hot water is mostly between 30-90 ℃. It is waste heat. If it is discharged directly, it will not only affect the environment, but also waste a lot of available heat energy. As an enterprise, in the face of rising gas...

Problems solved by technology

However, in the production process of dyeing and finishing, washing water, papermaking, chemical industry, bathing and other industries, a large amount of waste hot water will be discharged. The temperature of these waste hot water is mostly between 30-90 ℃. It is waste heat. If it is discharged directly, it will not only affect the environment, but also waste a lot of available heat energy in vain.
