There are significant differences between jet condensers and surface condensers in several ways, and here is a detailed analysis of the differences:
First, the working principle
Jet condenser
The jet condenser is a kind of condensing-based and exhaust-supplemented injector, which is a kind of hybrid condenser.
Its working principle is to generate negative pressure through high-speed water flow or other cooling medium injection, and then inhale the gas or vapor that needs to be condensed, and directly contact and mix with the cooling medium to achieve the condensation effect.
Surface condenser
The surface condenser works on the principle of heat exchange through the wall between the condensed substance and the coolant.
The coolant flows on the other side of the wall and is in indirect contact with the condensed substance, transferring heat through the wall to cool the condensed material and condense into a liquid.
2. Structure and characteristics
Jet condenser
The structure is relatively simple, and it is often used in vacuum evaporation equipment in pharmaceutical, sugar and other industries.
Due to the high mixing chamber and the built-in perforated baffle, the direct impact of the high-velocity air flow into the jet water column can be avoided, thus maintaining the condensation effect.
Surface condenser
The most commonly used is the tubular heat exchanger, which is similar in structure and working principle to the wall heat exchanger.
It is characterized by stable temperature control, and is suitable for processes that require certain physical and chemical properties such as product particles, viscosity, and corrosivity.
3. Application scenarios
Jet condenser
It is suitable for occasions that require fast and efficient condensation, such as vacuum evaporation, exhaust gas treatment, etc.
In some processes that require the simultaneous processing of gases and condensates, the jet condenser can be used as a mixing condenser and a vacuum pump.
Surface condenser
It is suitable for processes that require stable temperature control or have special requirements for product properties, such as deep processing of fuel oil, high-temperature heavy oil treatment, chemical reactors, etc.
In summary, there are significant differences between jet condenser and surface condenser in terms of working principle, structural characteristics and application scenarios. The choice of which type of condenser to choose depends mainly on factors such as specific process requirements, cooling effectiveness and economic benefits.
