Phase change type high-pressure electrode boiler

Abstract

The invention discloses a phase change type high-pressure electrode boiler. The phase change type high-pressure electrode boiler comprises supporting legs, a boiler shell, a phase change heat exchanger, a plurality of supporting seats, insulation heat-resisting seats, an inner cylinder, a plurality of high-pressure electrodes, water distributing plates, U-shaped distributing pipes, a water pipe, awater return pipe and a load adjusting pump; the boiler shell is arranged on the supporting legs; the phase change heat exchanger is arranged at the top; the plurality of supporting seats are arranged on the inner wall of the boiler shell; the insulation heat-resisting seat is arranged on each supporting seat correspondingly; the inner cylinder provided with water distributing holes and water dropping holes at the bottom is arranged on the insulation heat-resisting seats; the plurality of high-pressure electrodes are connected with an external circuit, positioned in a cavity of the inner cylinder and hung on the inner cylinder through insulators; the water distributing plates are arranged above water inlets at the bottom of the inner cylinder; the U-shaped water distributing pipes communicate with the water inlets at the bottom of the inner cylinder and are arranged at the bottom of the inner cylinder; the water pipe communicates with the bottom of the U-shaped water distributing pipes, and is connected with and extends out of the bottom of the boiler shell; the water return pipe is arranged at the bottom of the boiler shell; and the load adjusting pump is connected with the end of the water pipe and the end of the water return pipe, and can perform variable frequency control and adjust circulating water volume of the boiler. The phase change type high-pressure electrode boiler is reliable in operation, flexible in load adjustment and high in safety, and is widely applicable to clean energy consumption and power plate flexible modification.

Description

technical field [0001] The invention relates to a phase-change high-voltage electrode boiler, which can be widely used in clean energy consumption and flexible transformation of power plants. Background technique [0002] At the end of 2015, the installed capacity of hydropower, wind power and solar power in my country reached 320 million kilowatts, 131 million kilowatts and 42 million kilowatts respectively, ranking first in the world, and the total power generation capacity of renewable energy also ranked first in the world. In recent years, the problem of abandoning wind and solar in some areas of my country has become increasingly prominent. The development of the wind power industry in 2015 released by the National Energy Administration shows that the situation of wind power curtailment has intensified: the annual curtailment of wind power was 33.9 billion kWh, a year-on-year increase of 21.3 billion kWh, and the average wind curtailment rate was 15%. In 2016, the aver...

Problems solved by technology

[0004] However, at present, high-voltage electrode boilers often form the primary side of the heating network with partition wall heat exchangers, circulating water pumps, constant pressure devices, and dosing devices. The system is complex and occupies a large area; The shell is directly connected, the voltage of the equipment shell is high, and the equipment must be equipped with a well-insulated protective room

At the same time, in order to achieve the purpose of load regulation, the high-voltage electrode boiler often has moving parts inside the boiler, which increases the failure points of the boiler; the minimum load of some fully submerged electrode boilers can only reach 10%.
