Solid-liquid combined heat accumulating type electric boiler and heating method thereof

Abstract

The invention discloses a solid-liquid combined heat accumulating type electric boiler. The solid-liquid combined heat accumulating type electric boiler comprises a shell body and an inner container fixed inside the inner container, wherein the inner container is divided into a liquid heat accumulating area and a solid heat accumulating area, and the liquid heat accumulating area is arranged at the solid heat accumulating area in a semi-surrounded mode. The above structural solid-liquid combined heat accumulating type electric boiler is adopted, a dual heat accumulation mode of combining solidheat accumulation with liquid heat accumulation is adopted, the advantages of the solid heat accumulation and the advantages of the liquid heat accumulation are integrated, good balance is achieved on the unit volume heat accumulation amount and the equipment volume, it is guaranteed that under the condition that the volume is small, a whole heat accumulator is fully heated to the highest allowable temperature in the off-peak electricity period, sufficient heat supply can be achieved in other periods, and meanwhile, the water and electricity separation design is adopted, and the safety is higher.

Description

technical field [0001] The invention relates to an electric boiler technology, in particular to a solid-liquid combined heat storage electric boiler and a heating method thereof. Background technique [0002] At present, new problems have emerged in the development of my country's power industry and changes in power demand. The peak load of the power grid increases rapidly, and the load rate of the power grid decreases year by year. With the development of the economy, the peak-to-valley difference in urban electricity consumption in my country is increasing day by day. The huge power peak-to-valley difference and the peak growth rate inevitably put forward high requirements for power peak regulation, which poses a certain threat to the safe operation of the power grid. [0003] In addition, my country's urban heating is mainly based on regional boiler rooms and thermal power plants, and the fuel is mainly coal. The dust and harmful gas emissions caused by coal combustion ...

AI Technical Summary

Problems solved by technology

At present, the heat supply of the central heating system needs to be transported through the pipe network for a long distance, and there is no metering method and adjustment means at the end, and the user cannot adjust it, so the heat loss is large and the energy waste is serious.
