Embodiment 1

[0026] Embodiment one, see figure 1 , a direct heat exchange steam condensing device, including an installation chamber 1, a cooling device 2, a condensing impeller 3 and an exhaust impeller 4.

[0027] The bottom of the installation chamber 1 is provided with a steam inlet 11 and a liquid storage tank 12 . The liquid storage tank 12 is provided with a pure liquid discharge valve port 121 . The pure liquid discharge valve port 121 is provided with a pure liquid discharge valve 122 . The upper end of the installation chamber 1 is provided with a cooling chamber 13 . The bottom wall of the cooling chamber 13 protrudes toward the inside of the cooling chamber to form a recess 131 on the surface of the cooling chamber. The exhaust impeller 4 is accommodated in the recess 131 . A plurality of air pipes 16 penetrating the cooling chamber 13 are provided on the bottom wall of the pit 131 . A heat absorbing medium inlet 132 is provided on the wall of the cooling chamber 13 . The...

Embodiment 2

[0035] Embodiment two, see Figure 4 The difference from the first embodiment is that: the surface of each condensing impeller blade 31 is provided with a plurality of grooves 315 distributed along the axial direction of the condensing impeller. The groove 315 begins to extend along the outer end of the condensing impeller blade 31 until it abuts with the outlet end of the liquid outlet hole 322 . The liquid outlet hole 322 is arranged on the rotating shaft 32 of the condensing impeller. The condensing impeller blades 31 pass out of the drain channel 331 . One end of the condensing impeller blade 31 protruding from the condensing impeller housing 33 is provided with a guide surface 315 inclined backward along the rotation direction of the condensing impeller, ie, the direction D in the figure. The condensing impeller blades 31 are welded on the outer surface of the condensing impeller rotating shaft 32 . A cover 323 covering the inner end of the liquid outlet hole 322 is pr...

Abstract

A direct heat exchange type steam condensing device comprises a condensing impeller (3). The condensing impeller (3) comprises a plurality of condensing impeller vanes (31), a condensing impeller rotating shaft (32) for driving the condensing impeller vanes (31) to rotate and a synchronously-rotating liquid inlet channel (36) for conveying a heat-absorbing medium to surfaces of the condensing impeller vanes (31). The condensing impeller vanes (31) are distributed along the circumferential direction of the condensing impeller rotating shaft (32) and a steam channel (34) is formed between adjacent condensing impeller vanes (31). The steam and the heat-absorbing medium are in direct contact during motion, so the direct heat exchange type steam condensing device can improve the heat exchange efficiency, the heat exchange speed and the condensing effect.

Description

technical field [0001] The present invention relates to a condensing device, in particular to a condensing device which makes steam directly contact with a heat-absorbing medium to condense the steam. Background technique [0002] The conversion of vapor into liquid is carried out through a condensing device. The existing condensing device performs indirect heat exchange through a condensing tube, that is, the vapor and the medium used to absorb the heat of the vapor to cool the vapor into a liquid (hereinafter referred to as endothermic Medium) is separated by the condenser tube, one passes through the inside of the condenser tube, and the other passes through the outside of the condenser tube. [0003] A condensing device is disclosed in a patent document whose Chinese patent number is 972019146, the date of authorization announcement is January 20, 1999, and the title is "High Efficiency Vacuum Condenser". The device mainly consists of a condenser body and a condensa...
