At present, the commonly used shell and tube evaporator usually have a base fixed on the ground, and a cooling medium is passed through the pipeline. The cooling medium enters from one end of the shell tube, exchanges heat with the water in the pipeline and flows out from the other end of the shell tube.
Due to gravity and other reasons, after the cooling medium enters the shell tube, it cannot be evenly distributed in the shell tube. There is more cooling medium near the cooling medium inlet and the position close to the ground, but far away from the cooling medium inlet and the cooling medium outlet. The cooling medium is small, so it is easy to have the problem of uneven heat exchange.
The present technology provides a shell and tube evaporator that can solve the problem of uneven heat exchange in the cooling process in the prior art, including a spray tube assembly and a cooling tube; wherein: the cooling medium can be evenly distributed in the cooling The spray pipe assembly in the pipe is installed on the cooling pipe.
1. A shell and tube evaporator, comprising: a spray tube assembly and a cooling tube; wherein: the spray tube assembly that enables the cooling medium to be evenly distributed in the cooling tube is installed in On the cooling pipe.
2. The shell and tube evaporator according to claim 1, wherein the spray tube assembly comprises: a cooling medium pipeline and a plurality of spray heads; wherein: the plurality of spray heads are evenly installed in The cooling medium pipeline.
3. The shell and tube evaporator according to claim 2, further comprising: a flow control device; wherein: the flow control device for adjusting the flow of the cooling medium is installed on the spray pipe assembly.
4. The shell and tube evaporator according to claim 3.
