Steam generation system intelligently controlled according to inlet steam pressure

Abstract

The invention provides an evaporator system. The evaporator system comprises an evaporator and steam utilization equipment; steam generated by heating in the evaporator enters the steam utilization equipment through a steam inlet pipe, is subjected to sufficient heat exchange and utilization in the steam utilization equipment, and then is recycled and mixed into the evaporator for heating; the evaporator comprises a steam chamber, an electric heating device is arranged in the steam chamber, a steam outlet pipeline is arranged at the upper part of the steam chamber, and a water inlet pipeline is arranged in the steam chamber; a pressure sensor is arranged on the steam inlet pipe of the steam utilization equipment and is used for measuring the pressure in the steam inlet pipe; and the pressure sensor and the electric heating device are in data connection with a controller, and the controller automatically controls the heating power of the electric heating device according to the pressuremeasured by the pressure sensor. According to the steam generation system intelligently controlled according to inlet steam pressure, by means of the arrangement, the heating power can be adjusted according to the pressure of the steam inlet pipe 21, so that it is guaranteed that the heat exchange amount of the steam utilization equipment meets the requirement, and meanwhile the safety of the evaporator is guaranteed under the condition that steam output is maximized.

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, bun shops, canteen , restaurant , factories and mines, soy products factories etc. 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 aims at improving ...

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.
