Valley electricity heat storage steam boiler system

Abstract

The invention discloses a valley electricity heat storage steam boiler system. According to the valley electricity heat storage steam boiler system, a water treatment system, a water treatment water supply pump, a softened water tank, a softened water supply pump, a liquid level device and a water inlet pipeline electric valve are sequentially arranged on a water inlet pipe according to the waterflow direction, the water inlet pipeline electric valve is connected to a steam-liquid phase change steam heat storage tank through an electric steam boiler, a steam-liquid conversion device is arranged at the connecting end of the steam-liquid phase change steam heat storage tank and the electric steam boiler, a steam supply pipeline is arranged at the upper left end of the steam-liquid phase change steam heat storage tank, a steam supply check valve and a steam supply pneumatic valve are sequentially arranged on the steam supply pipeline in the steam supply direction, a controller is arranged at the upper right end of the steam-liquid phase change steam heat storage tank, a blow-off pipeline is arranged at the bottom end of the steam-liquid phase change steam heat storage tank, and a blow-off electric valve is arranged on the blow-off pipeline. The valley electricity heat storage steam boiler system has the advantages that the electric boiler can be heated by utilizing valley electricity at night and stored for supplying steam required by industrial enterprises in the daytime, and the system is economical, efficient, low-carbon and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of heat storage and steam supply, in particular to a valley electricity heat storage steam boiler system. Background technique [0002] Nowadays, heating is used in many places. For example, coal-fired boilers are used to provide heat to residents in winter in the north. Coal-fired boilers will not only produce a lot of waste gas, cause smog, and pollute the environment; Electric boilers, although the use of electric boilers can effectively solve the problem of environmental pollution, most of them are used during the day, such as important industrial enterprises, hospitals, hotels, etc., which need to supply steam at any time, or the power generation load of small thermal power plants is not stable and the industrial steam load is different. Balance, on the one hand, will cause electricity consumption pressure, on the other hand, it will also increase economic expenditure; now it is urgent to use the valley...

[0002] Nowadays, heating is used in many places. For example, coal-fired boilers are used to provide heat to residents in winter in the north. Coal-fired boilers will not only produce a lot of waste gas, cause smog, and pollute the environment; Electric boilers, although the use of electric boilers can effectively solve the problem of environmental pollution, most of them are used during the day, such as important industrial enterprises, hospitals, hotels, etc., which need to supply steam at any time, or the power generation load of small thermal power plants is not stable and the industrial steam load is different. Balance, on the one hand, it will cause pressure on electricity consumption, on the other hand, it will also increase economic expenditure; now it is urgent to use the valley electricity at night to heat the electric boiler, and store it for the steam needed during the day
