Steam heat exchanger with steady flow structures

Abstract

The invention provides a steam heat exchanger. The steam heat exchanger comprises a header and a steam pipe; steady flow devices are arranged inside the steam pipe and are each of a sheet structure; the sheet structures are arranged on the cross section of the steam pipe; the steady flow devices are composed of square through holes and right octagon through holes; the length of each side of the square through holes is equal to the length of each side of the right octagon through holes; the four sides of each square through hole are the sides of four different right octagon through holes; and the four spaced sides of each right octagon through hole are the sides of four different square through holes. Compared with a steady flow device in the prior art, the steam heat exchanger with the steady flow structures further improves the steady flow effect, enhances heat transfer and is easy to manufacture.

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.
