[0002] For some heat transfer processes, such as cooling of gas or condensation of water vapor, hot and cold fluids can be directly mixed for heat exchange; this heat exchange method is only applicable to processes that allow the two fluids to be mixed with each other; this heat exchange The advantage of this method is that the heat transfer effect is good and the equipment structure is simple; the equipment used in this heat exchange method is called a hybrid condenser, and the parallel flow low-level condenser is a commonly used hybrid condenser with a simple structure. The traditional parallel flow Low-level condenser, the baffle plate of the cooling water is horizontal, the residence time of the cooling water in the condenser is short, and the contact between the steam and the cooling water is not sufficient

The invention relates to a parallel-flow low-lying condenser, which comprises a shell. A steam inlet pipe is arranged at the upper end of the shell. A condensate outlet pipe is arranged at the lower end of the shell. A sprayer is arranged at the steam inlet of the steam inlet pipe. Deflectors are arranged on the inner wall of the shell. One side of each deflector is fixedly arranged on the inner wall and the other side of each deflector is provided with a baffle which is upwards perpendicular to the deflector. The lower end of the sprayer is connected with a water inlet pipe which penetrates through the wall of the shell. The water spraying side of the sprayer is upwards arranged. The parallel-flow low-lying condenser has the advantages that the staying time of cooling water in the condenser can be prolonged to enable steam to be in full contact with the cooling water and the mixing ratio is improved.
