Problems solved by technology
When the tube-and-tube indirect condenser is used, the material droplets entrained in the secondary steam will not pollute the cooling water, which is suitable for occasions where the material is highly corrosive. The consumption is large, and an additional vacuum pump is required to extract non-condensable gas, and the power consumption is high
The multi-layer perforated plate direct condenser uses cooling water and secondary steam to directly contact and condense, and the condensation effect is better, but the aperture of the perforated plate is small, and it is easy to be blocked during long-term operation
When the direct condenser is operated in reverse flow, it is easy to cause liquid flooding, or the cooling water is mixed back into the evaporation chamber, which cannot achieve the effect of condensation and vacuuming, and it is also necessary to configure a vacuum pump to extract non-condensable gas
"Chemical Equipment Technology" 1997: 18 (1) reported the "Design and Application of Self-exhausting Non-Condensable Gas Atmospheric Condenser" introduced by Chen Xiaoxiang, but the vapor-liquid contact element they used was still a multi-layer porous plate with parallel flow During operation, the secondary steam is likely to cause a short circuit, the steam distribution effect is not good, and the contact with the cooling water is poor

Embodiment Construction
[0015] The rotary vane condenser of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] The 1000kg / h secondary steam evaporated from the second effect evaporation chamber of a two-effect vacuum evaporation system enters and circulates the liquid-type steam condenser 1 through the inlet pipe 3, and the diameter of the steam condenser 1 used is 300mm, and three pieces are set. Cyclone vapor-liquid mixing element 2, the blades of the first and third mixing elements are installed clockwise, the blades of the second blade are installed counterclockwise, the installation distance is 200mm, and the third hydrocyclone vapor-liquid mixing element at the bottom The distance to the water outlet at the lower part of the condenser is 1000mm. The number of blades of the cyclone-type gas-liquid mixing element 2 is 8 pieces, and the blade spacing is 20mm; the inclination angle between the blade and the bottom surface is 10°, and the ...

The invention provides a rotary vane type condenser. The rotary vane type condenser consists of rotary vane type vapor-liquid mixing elements, a cylindrical cylinder, a cover plate, a conical lower sealing head, a vapor inlet pipe, a water inlet pipe, a distributor, a water outlet pipe, a support device and the like. Vapor and cooling water are fully mixed and exchanged the heat through the rotary vane type vapor-liquid mixing elements in a manner of parallel flow in the same direction; the vapor is condensed; and non-condensable gas in the vapor flows out with a water current flowing with high speed. The rotary vane type condenser has the characteristics of good condensation effect, simple structure and self discharge without gas condensation, and can be used for condensation and vacuum systems of last-effect secondary vapor in a vacuum evaporation process in such fields as chemical engineering, pharmacy, petroleum, foods and waste water treatment.
Description
technical field [0001] The invention relates to a rotary vane condenser, which relates to a steam condensation technology, in particular to a device for secondary steam condensation and self-discharge of non-condensable gas in a vacuum evaporation system, which belongs to the field of chemical equipment. Background technique [0002] Vacuum evaporation is often used in chemical, pharmaceutical, petroleum, food, wastewater treatment and other fields to achieve evaporation and concentration of solutions. The secondary steam generated during the evaporation process needs to be condensed with cooling water, and the non-condensable gas is discharged to maintain the vacuum operation of the evaporation process. [0003] At present, the widely used condensers include tube-and-tube indirect condensers and multi-layer porous plate direct condensers. When the tube-and-tube indirect condenser is used, the material droplets entrained in the secondary steam will not pollute the cooling w...
