As a leading manufacturer in environmental technology, Qingdao Conqinphi Environmental Technology Group is proud to present our specialized Chemical Reactor Low-Pressure Condensed Liquid Flash Evaporator Water Recovery Tank. Designed for efficiency and reliability, this integrated system is engineered to handle the demanding requirements of solvent recovery, concentration processes, and wastewater minimization across various industries. With over eight years of manufacturing expertise since 2015 and a substantial 10,000-30,000 square meter production facility, we deliver robust solutions that help our global clients reduce operational costs and enhance their environmental sustainability. This system represents a core component in modern chemical processing, where recovering valuable materials and reducing effluent volume are paramount.
Our flash evaporator system is specifically designed for operations under reduced pressure, which significantly lowers the boiling point of liquids. This feature is crucial for processing heat-sensitive compounds or for achieving energy savings. The system typically integrates a reactor vessel for initial processing, a flash chamber for instantaneous evaporation, and a condenser with a dedicated recovery tank for collecting the distilled output.
Core System Advantages & Technical Specifications:
- Energy Efficient Design: Low-pressure (vacuum) operation allows evaporation at much lower temperatures compared to atmospheric systems, leading to substantial savings on heating energy.
- High Recovery Rate: Engineered for maximum separation efficiency, ensuring a high yield of recovered water or solvent, which can often be reused in the process, reducing raw material costs.
- Gentle Processing: The low-temperature evaporation is ideal for temperature-sensitive chemicals, pharmaceuticals, or food-grade products, preventing thermal degradation.
- Corrosion Resistance: Constructed from high-grade materials like SS316L or lined carbon steel to withstand aggressive chemical environments and ensure long service life.
- Scalable & Customizable: Available in a wide range of capacities and configurations to match specific production throughputs, from pilot-scale R&D to full-scale industrial manufacturing.
- Integrated Safety: Designed with pressure relief, temperature controls, and level indicators to ensure safe operation under vacuum conditions.
The system's operation is straightforward: Pre-heated liquid from the reactor is introduced into the flash chamber, where the sudden pressure drop causes instantaneous vaporization. The vapor is then condensed and collected in the water recovery tank, while the concentrated residue is removed from the bottom of the evaporator.

Frequently Asked Questions (FAQ):
-
Q: What is the primary advantage of using a low-pressure (vacuum) flash evaporator?
A: The main advantage is energy savings. By operating under vacuum, the boiling point of the liquid is significantly lowered. This allows evaporation to occur at a much lower temperature, reducing the thermal energy required and making it safe for heat-sensitive materials. -
Q: Can this system handle corrosive chemicals?
A: Yes. The system's wetted parts can be constructed from corrosion-resistant materials such as stainless steel 316L, Hastelloy, or carbon steel with protective linings like PTFE or glass, depending on the chemical compatibility requirements of your process. -
Q: What is the typical recovery rate for water or solvent?
A: Recovery rates are highly dependent on the feed composition and operating conditions. In many applications, recovery rates of 90% or higher for the volatile component (water/solvent) can be achieved. A detailed process analysis is recommended for a specific estimate. -
Q: Is the system automated?
A: The level of automation is customizable. Systems can range from manual valve operation to fully automated PLC-controlled setups with touchscreen HMIs, integrating pumps, valves, and sensors for parameters like pressure, temperature, and level. -
Q: How do you determine the right size/capacity for our needs?
A: Sizing is based on key process parameters you provide: the feed flow rate, the initial and desired final concentration, the properties of the liquid, and the required evaporation rate. Our engineering team will perform the necessary calculations to recommend an optimal size. -
Q: What kind of maintenance does this equipment require?
A: Maintenance is generally straightforward. It involves regular inspection of seals and gaskets, cleaning of heat exchange surfaces (especially if fouling is expected), and calibration of instruments. We provide detailed operation and maintenance manuals. -
Q: Can you provide a skid-mounted unit?
A: Yes. We often deliver pre-assembled skid-mounted systems. This approach minimizes on-site installation time and cost, ensures factory-tested integrity, and simplifies logistics. -
Q: What is your lead time for a standard unit?
A: Lead times vary based on complexity, size, and material selection. For a standard mid-range system, typical production lead times range from 8 to 16 weeks. We provide a confirmed schedule upon order placement.
