Description

TECHNICAL FIELD

[0001] The utility model relates to the field of waste heat recycling, especially to a low-temperature evaporation waste heat recycling device. BACKGROUND

[0002] With the growth of global energy demand and the improvement of environmental protection awareness, the research and development of high-efficiency energy-saving technology and equipment have become the focus of the industry. Especially in the fields of chemical industry, pharmaceutical industry, food processing, etc., a large amount of low-grade waste heat generated during low-temperature evaporation is often wasted, resulting in serious energy loss. In recent years, various waste heat recovery technologies have emerged, aiming to reduce production costs and environmental impact by effectively utilizing these low-grade waste heat. Since the heat in low-density energy (such as water and air) is transferred to the wastewater to be evaporated through heat pump technology, and the saturated wet steam after evaporation is directly discharged into the air, it will cause heat loss and also carry away a large amount of water vapor, causing waste of water resources.

The cold medium outlet of the water source water heater is connected to the cold medium inlet of the waste heat release heat exchanger through a pipeline. The gas outlet at the top of the evaporation unit is connected to the hot medium inlet of the waste heat absorption heat exchanger. The cold medium outlet of the waste heat absorption heat exchanger is connected to the hot medium inlet of the waste heat release heat exchanger. The hot medium outlet of the waste heat release heat exchanger is connected to the cold medium inlet of the waste heat absorption heat exchanger. The advantage is that the waste heat release heat exchanger and the water source water heater are connected in series to form a two-stage heating system, ensuring the temperature of the evaporated wastewater and reducing the load of the water source water heater. The evaporated water is condensed and recycled, and after biochemical treatment, it can be used for dust removal and greening, reducing the water consumption of fresh water in enterprises.

Therefore, a low-temperature evaporation waste heat recycling device is proposed. UTILITY MODEL CONTENTS
