低溫熱泵型廢水/廢溶劑-再生/濃縮提純系統CT-HP

    機加工技術廣泛應用於機器製造、輕工、電子等行業,是全球三大污染行業之一。因為其本身成分複雜,所含的有害物質也相對較多,所以機加工/表面處理廢水/廢溶劑是相對難以應付的。隨著我國經濟的快速發展,對機加工產品的需求日益增加, 機加工廢水的排放量與日俱增。而廢水中含有大量污染物質,一旦處理不當排入環境當中,對人的健康以及生態環境造成極大的破壞。目前,機加工廢水主要的處理方法分為化學法、物理法和生物法。但化學處理法污泥量大,會產生二次污染;物理法設備複雜,且能耗大;生物法對於水質的要求高。傳統的處理方法都存在一定的局限性。

1.2 工作原理

該系統的核心概念是利用熱泵的低能源成本(對比電加熱/冷卻-只用1/6~1/5電能)和減壓蒸餾的低沸點(30~40)來達成最高的經濟效應

熱泵是一種將低溫熱源的熱能轉移到高溫熱源的裝置。通常用於熱泵裝置的低溫熱源是我們周圍的介質——空氣、河水、海水,或者是從工業生產設備中排出的廢熱,這些工質常與周圍介質具有相接近的溫度。熱泵裝置的工作原理與壓縮式製冷機是一致的;是由壓縮機排出的高壓製冷劑蒸汽,流入蒸發室,製冷劑蒸汽冷凝時放出的潛熱,將蒸發室廢水/廢溶劑加熱,達到蒸發的目的,冷凝後的液態製冷劑,從膨脹閥進入冷凝器,吸收外界熱量而蒸發產生極冷達到冷凝蒸氣成液態回收,蒸發後的製冷劑蒸汽經過氣液分離後被壓縮機吸入,完成制熱蒸發/冷卻回收循環。這樣,將迴圈冷卻水中的熱量入溫度較高的蒸發室內,故稱為熱泵熱泵蒸發技術是作為現今最先進和最高效的蒸發技術在歐美國家被廣泛應用於各個行業物料和廢水濃縮,結晶及乾燥。

Ct-hp of low temperature heat pump wastewater / waste solvent regeneration / concentration and purification system

 

Machining technology is widely used in machine manufacturing, light industry, electronics and other industries. It is one of the three major polluting industries in the world. Because of its complex composition and relatively more harmful substances, machining / surface treatment wastewater / waste solvent is relatively difficult to cope with. With the rapid development of China's economy, the demand for machining products is increasing day by day. Wastewater contains a large number of pollutants, once improperly treated and discharged into the environment, it will cause great damage to human health and ecological environment. At present, the main treatment methods of machining wastewater are chemical method, physical method and biological method. However, due to the large amount of sludge in chemical treatment process, secondary pollution will be produced; the physical process equipment is complex and energy consumption is high; biological process has high requirements for water quality. The traditional treatment methods have some limitations.

 

Yuhe technology combines heat pump energy-saving technology with vacuum distillation method in wastewater / waste solvent regeneration / concentration and purification treatment. The whole process advocates physical recovery to reduce the use of chemical raw materials and the generation of secondary waste, which is attracting more and more attention. The system has the advantages of low technical difficulties, suitable for small and medium-sized equipment, insensitive to water quality, and can be combined with low-grade energy. It is a broad-spectrum wastewater / waste solvent regeneration / concentration and purification technology.

 

1.1 system composition

 

The heat pump wastewater / waste solvent regeneration / concentration system mainly consists of evaporation separator, heater condenser and heat pump system. The details are shown in Figure 1.

 

1.2 working principle

 

The core concept of the system is to use the low energy cost of heat pump (compared with electric heating / cooling - only 1 / 6 ~ 1 / 5 electric energy) and low boiling point of vacuum distillation (about 30 ~ 40 degrees) to achieve the highest economic effect.

 

Heat pump is a device that transfers heat from low temperature heat source to high temperature heat source. Usually, the low-temperature heat source used in heat pump device is the surrounding medium air, river water, sea water, or waste heat discharged from industrial production equipment. These working fluids often have a temperature close to the surrounding media. The working principle of the heat pump device is the same as that of the compression refrigerator; the high-pressure refrigerant steam discharged from the compressor flows into the evaporation chamber, and the latent heat released when the refrigerant vapor condenses will heat the waste water / waste solvent in the evaporation chamber to achieve the purpose of evaporation. The condensed liquid refrigerant enters the condenser from the expansion valve, absorbs the external heat and evaporates to produce extremely cold condensate steam After evaporation, the refrigerant vapor is absorbed by the compressor after gas-liquid separation to complete the heating evaporation / cooling recovery cycle. In this way, the heat of loop cooling water is "pumped" into the evaporation chamber with higher temperature, so it is called "heat pump". As the most advanced and efficient evaporation technology, heat pump evaporation technology is widely used in various industries in Europe and the United States.
