蒸發單元​

Evaporation unit

蒸發單元是低溫廢水回收設備的關鍵部分，主要包括蒸發釜、加熱裝置、真空係統等組件。蒸發釜通常采用耐腐蝕的不鏽鋼材質製作，能夠承受一定的壓力和溫度變化，且內部結構設計合理，有利於廢水的均勻分布和蒸發效率的提升。加熱裝置一般采用電加熱、蒸汽加熱或熱水加熱等方式，為廢水蒸發提供所需的熱量。真空係統則通過真空泵將蒸發釜內的空氣抽出，維持低壓環境，確保廢水在低溫下能夠順利蒸發。例如，在某食品加工企業的低溫廢水回收設備中，蒸發釜采用雙層不鏽鋼結構，中間填充保溫材料，減少熱量散失，加熱裝置采用蒸汽加熱，通過精確控製蒸汽流量，實現對蒸發溫度的精準調控，真空係統配備高性能真空泵，能夠快速將蒸發釜內壓力降至設定值。​

The evaporation unit is a key component of low-temperature wastewater recovery equipment, mainly including evaporation kettle, heating device, vacuum system and other components. Evaporation kettles are usually made of corrosion-resistant stainless steel materials, which can withstand certain pressure and temperature changes. The internal structure design is reasonable, which is conducive to the uniform distribution of wastewater and the improvement of evaporation efficiency. Heating devices generally use methods such as electric heating, steam heating, or hot water heating to provide the required heat for wastewater evaporation. The vacuum system extracts the air from the evaporator through a vacuum pump to maintain a low-pressure environment, ensuring that the wastewater can evaporate smoothly at low temperatures. For example, in the low-temperature wastewater recovery equipment of a certain food processing enterprise, the evaporation kettle adopts a double-layer stainless steel structure, with insulation material filled in the middle to reduce heat loss. The heating device adopts steam heating, and the evaporation temperature is precisely controlled by precisely controlling the steam flow rate. The vacuum system is equipped with a high-performance vacuum pump, which can quickly reduce the pressure inside the evaporation kettle to the set value. ​

冷凝單元​

Condensation unit

冷凝單元由冷凝器、冷卻介質循環係統等構成。冷凝器的類型多樣，常見的有列管式冷凝器、板式冷凝器等。列管式冷凝器具有換熱效率高、結構緊湊等優點，適用於處理量大的場合；板式冷凝器則具有占地麵積小、清洗維護方便等特點。冷卻介質循環係統負責將冷卻介質（如水或空氣）輸送至冷凝器，吸收水蒸氣的熱量後，再通過冷卻塔或其他散熱裝置進行冷卻，循環使用。例如，在某電子製造企業的低溫廢水回收設備中，采用板式冷凝器進行水蒸氣冷凝，冷卻介質為循環水，通過水泵將冷卻水泵送至冷凝器，吸收熱量後的熱水進入冷卻塔進行散熱降溫，然後再回到冷凝器循環使用，實現了冷卻介質的高效循環利用。​

The condensing unit consists of a condenser, a cooling medium circulation system, etc. There are various types of condensers, including tubular condensers and plate condensers. The tubular condenser has the advantages of high heat transfer efficiency and compact structure, and is suitable for applications with large processing capacity; Plate condenser has the characteristics of small footprint, easy cleaning and maintenance. The cooling medium circulation system is responsible for transporting the cooling medium (such as water or air) to the condenser, absorbing the heat of water vapor, and then cooling it through a cooling tower or other heat dissipation device for recycling. For example, in a low-temperature wastewater recovery equipment of an electronic manufacturing enterprise, a plate condenser is used for water vapor condensation, and the cooling medium is circulating water. The cooling water is pumped to the condenser through a water pump, and the hot water that absorbs heat enters the cooling tower for heat dissipation and cooling, and then returns to the condenser for recycling, achieving efficient recycling of the cooling medium. ​

控製係統​

Control system

控製係統是低溫廢水回收設備的 “大腦”，負責對設備的運行參數進行監測和調控。通過傳感器實時監測蒸發釜內的溫度、壓力，以及冷凝水的水質、流量等參數，並將數據傳輸至控製器。控製器根據預設的參數範圍，自動調節加熱裝置的功率、真空係統的抽氣速率、冷卻介質循環係統的流量等，確保設備始終處於最佳運行狀態。例如，當蒸發釜內溫度過高時，控製器自動降低加熱裝置的功率；當冷凝水水質出現異常時，控製器發出警報並啟動相應的淨化處理程序，保障了設備運行的穩定性和回收水的質量。

The control system is the "brain" of the low-temperature wastewater recovery equipment, responsible for monitoring and regulating the operating parameters of the equipment. Real time monitoring of temperature, pressure, condensate water quality, flow rate, and other parameters inside the evaporator kettle through sensors, and transmission of data to the controller. The controller automatically adjusts the power of the heating device, the pumping rate of the vacuum system, the flow rate of the cooling medium circulation system, etc. according to the preset parameter range, to ensure that the equipment is always in the optimal operating state. For example, when the temperature inside the evaporator is too high, the controller automatically reduces the power of the heating device; When the quality of condensate water is abnormal, the controller issues an alarm and starts the corresponding purification treatment program, ensuring the stability of equipment operation and the quality of recovered water.
