Abstract

The invention relates to a valley current steam boiler adopting heat condition oil to transfer heat and a method for preparing steam. The boiler comprises an electric heating device, an energy storage device, a steam output device and a heat transfer medium pipeline. Heat transfer medium heat conduction oil can flow in the heat transfer medium pipeline in a circulation mode and transfers heat in the electric heating device or the energy storage device to the steam output device. The electric heating device comprises an electric heating element and a heat conduction oil buffer tank, wherein the electric heating element is started at the valley current period. The energy storage device comprises a heat storage substance. The steam output device comprises a steam generator and a preheater which are sequentially connected through the heat transfer medium pipeline. By means of the method, on one hand, the cheap valley current is utilized to generate steam which is used in the peak current time, the economical benefit is good, energy is saved, and the environment is protected; on the other hand, molten salt is utilized to store heat, the molten salt is high in use temperature and high in energy storage efficiency, and the stored heat ensures that the heat provided by the valley current can be utilized continuously in the valley current period in 24 hours to conduct heating to generate steam.

Description

technical field [0001] The invention relates to the field of electric steam boilers, in particular to an electric steam boiler which utilizes valley electricity and can store energy and a method for preparing steam. Background technique [0002] Electric steam boilers have been widely used in daily life and industrial fields because of their convenient use, simple operation, and energy transmission not limited by time and place. However, the existing electric steam boiler can only be heated during the use time, and its usual use time in daily life is during peak power hours, resulting in high energy costs. Therefore, how to reduce the cost of the electric steam boiler and have high economy to ensure the practicability is the key research direction at this stage. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a valley electric steam boiler with energy storage function for heat transfer through heat transfe...
