Self-heat-accumulating type electrical heating pressure variable steam boiler device

Abstract

The invention relates to a self-heat-accumulating type electrical heating pressure variable steam boiler device which comprises an electrical heating boiler, a heat accumulator, an external steam-water separator and a boiler water filling tank. The electrical heating boiler and the heat accumulator are integrally designed, the heat accumulator is arranged in the electrical heating boiler, and a steam outlet interface arranged on the upper portion of an electrical heating boiler body is connected with a steam inlet arranged on the external steam-water separator through a first pipe. A main steam valve, a micro-hole energy saving filter, a Y-shaped slow flow pipe and a steam reducing valve are sequentially arranged on the first pipe. A steam valve is arranged on the upper portion of the external steam-water separator, a drain outlet arranged on the lower portion of the external steam-water separator is connected with an inlet of the boiler water filling tank through a second pipe, and a drain valve and a filter are sequentially arranged on the second pipe. An outlet arranged on the lower portion of the boiler water filling tank is connected with a water inlet of the electrical heating boiler body through a third pipe. The self-heat-accumulating type electrical heating pressure variable steam boiler device greatly reduces device manufacture cost, can achieve concentrated control, and is energy-saving and efficient.

Description

technical field [0001] The invention relates to the technical field of heat storage steam boilers, in particular to a self heat storage electric heating variable pressure steam boiler device. Background technique [0002] At present, with the energy-saving and environmental protection strategies advocated by the country, the "DSM" operation mode implemented by the national power department can make full use of low-valley electricity prices for heat storage operation for enterprises to develop, turn off electric boilers during peak hours of the power grid, and release heat from heat storage media. Regenerative electric heating boilers have great market significance. This product is mainly used in the peak and valley of the factory's electricity load, which can effectively reduce the factory's operating costs, and can be released instantly after energy storage to improve work efficiency.

[0003] The electric heating heat storage steam boiler equipment currently on the market, the electric boiler is separated from the heat storage device, the heat storage device has a complex structure, slow heat storage speed, and unstable operation

Among them, the steam-water separation effect is not ideal, and the steam carries a high water rate, which cannot meet many working conditions that require high steam quality. Moreover, the built-in steam-water separation components are inconvenient to repair, and the maintenance and use costs are relatively high.
