Steam heat exchanger with variable spacing of flow stabilization structures

Abstract

The invention provides a steam heat exchanger. The steam heat exchanger includes a collecting box and steam pipes. Flow stabilization devices are arranged in the steam pipes. The multiple flow stabilization devices are arranged in the steam pipes. The spacing among the flow stabilization devices becomes smaller and smaller in a direction extending upward from inlets of the steam pipes. The steam heat exchanger of the invention further improves the flow stabilization effect and strengthens heat transfer through the spacing variation of the flow stabilization devices and is simple in manufacturing.

Description

technical field [0001] The invention relates to the fields of boiler technology and heat exchangers, in particular to an intelligently controlled evaporator and a steam heat exchanger thereof. Background technique [0002] An evaporator is a mechanical device that uses heat from fuel or other energy sources to heat water into steam. The evaporator has a wide range of applications, and is widely used in garment factories, dry cleaners, restaurants, steamed bun shops, canteens, restaurants, factories and mines, bean products factories and other places. The steam generation system includes an evaporator, and the steam generated by the evaporator is generally used in a steam utilization device, but there is a lack of corresponding intelligent control adjustment between the steam utilization device and the evaporator, such as controlling the steam generation of the evaporator according to the conditions of the steam utilization equipment. Therefore, the present invention mainly ...

AI Technical Summary

Problems solved by technology

During the evaporation process of the heat exchange tube, liquid will inevitably be carried into the steam tube. At the same time, due to the exothermic condensation at the condensation end, there will be liquid in the condensation end, and the liquid will inevitably enter the steam tube, so that the fluid in the heat exchange tube will It is a vapor-liquid mixture. The existence of a vapor-liquid mixture causes the gas to mix together, and the heat transfer capacity between the gas and the liquid decreases, which greatly affects the heat transfer efficiency.
