Abstract

The invention discloses a spraying mass transfer type condenser. The condenser comprises a plurality of finned condensing tubes, a water collecting disk and a fan, wherein the plurality of finned condensing tubes are distributed in a circular shape, the water collecting disk is arranged below finned condensing tubes, a secondary steam header pipe is connected above finned condensing tubes, spraying pipes which are distributed in a circular shape are arranged inside the plurality of finned condensing tubes which are distributed in a circular shape, and atomizing nozzles are arranged on spraying pipes. The spraying mass transfer type condenser atomizes water through atomizing nozzles, sprays the water to surfaces of finned condensing tubes for heat absorption and evaporates the water. By the aid of the convective heat transfer having phase changes, the heat exchange coefficient is greatly improved, the condensing energy consumption is greatly saved, besides, the secondary steam header pipe is located above finned condensing tubes, so that the direction of high-speed steam is consistent with the direction of condensed water, the film condensation inside tubes can be prevented effectively, and the heat transfer coefficient is improved.

Description

technical field [0001] The invention belongs to a condensation device, in particular to a spray mass transfer condenser of a vacuum concentration device. Background technique [0002] At present, the condensing part of domestic vacuum concentration equipment generally adopts tube condensers, mixers or hydraulic ejectors. All methods use single-phase fluid heat transfer with cooling water as the heat carrier, that is, the cooling water does not undergo phase change during the cooling process, the amount of water transported during the condensation process is large, the power of the circulating pump is large, and all The form must be equipped with a cooling tower, and the water cooled by the cooling tower is sent to the condenser again. The characteristics of various traditional condensers are: large area, large water transportation volume, high energy consumption, poor vacuum effect, etc. Contents of the invention [0003] The object of the present invention is to provide...
