Description:
The spiral plate heat exchanger is a new type of heat exchanger with good heat transfer efficiency and high operational stability, and multiple units can work together. Spiral plate heat exchanger is a kind of high-efficiency heat exchanger equipment, suitable for steam-steam, steam-liquid, liquid-liquid, heat transfer to liquid.
Features:
1. High heat transfer efficiency (good performance)
It is generally believed that the heat transfer efficiency of the spiral plate heat exchanger is 1-3 times that of the tubular heat exchanger. There is no flow dead zone in the uniform cross-section single channel, and the disturbance of the fixed distance column and the spiral channel to the flow reduces the critical Reynolds number of the fluid. The heat transfer coefficient of the spiral plate heat exchanger can reach 3000W/(㎡. K).
2. Effective recovery of low temperature heat energy
The spiral plate heat exchanger is made of two rolls, which recover waste heat and make full use of low-temperature heat energy.
3. Strong operational reliability
The end surface of the spiral channel of the non-detachable spiral plate heat exchanger is welded and sealed, so it has high sealing performance and ensures that the two working media are not mixed.
4. Low resistance
The connection pipe on the shell adopts a tangential structure. Relatively low pressure loss, processing large-volume steam or gas; self-cleaning ability, because the medium flows in a spiral, dirt is not easy to deposit; easy to clean, can be washed with steam or lye, simple and easy, suitable for installing cleaning devices; The medium goes through a single channel, allowing the flow rate to be higher than other heat exchangers.
5. Multiple units can be used in combination
When a single device cannot meet the requirements for use, multiple devices can be used in combination, but the following requirements must be met when combined: parallel combination, series combination, and the same distance between devices and channels. Mixed combination: One channel is connected in parallel and one channel is connected in series.
Applications:
Used in chemical, petroleum, solvent, medicine, food, light industry, textile, metallurgy, steel rolling, coking and other industries
