Energy storage device for boiler waste heat recovery

Abstract

The invention provides an energy storage device for boiler waste heat recovery, which comprises a closed structure I and a closed structure II which can be butted with each other and form a closed space, a boiler is arranged in the closed space, a thermoelectric power generation assembly is arranged in the closed space, and steam assemblies are respectively arranged in the closed structure I and the closed structure II. The first sealing structure comprises a first horizontally-arranged bottom plate, a first arc-shaped cover vertically arranged on the first bottom plate, a first upper air bag arranged on the inner side of the first arc-shaped cover and a first top cover arranged at the top end of the first arc-shaped cover, and a first lower air bag is further arranged on the bottom end face of the first bottom plate and arranged below the first upper air bag. The first lower air bag is in separable contact with the ground. According to the energy storage device for boiler waste heat recovery, the technical problem of how to efficiently recycle boiler waste heat is solved, heat energy in the boiler is converted into electric energy, and energy loss is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of boiler equipment, and in particular relates to an energy storage device for boiler waste heat recovery. Background technique [0002] During the use of boilers in iron and steel enterprises, a large amount of fuel is usually consumed, accompanied by a large amount of flue gas, and the exhaust gas temperature of the boilers used in iron and steel enterprises is also very high. In the past, these high-temperature flue gases were directly discharged to the atmosphere , resulting in a huge waste of resources. At present, in order to save energy, many technologies have been produced to recover the waste heat of this high-temperature flue gas. In the existing technology, the waste heat recovery and utilization facilities usually used are heat exchangers, but Because the flue gas temperature fluctuates sharply and the dust content is large, the ordinary water tube waste heat boiler is difficult to be used in the...

Problems solved by technology

[0002] During the use of boilers in iron and steel enterprises, a large amount of fuel is usually consumed, accompanied by a large amount of flue gas, and the exhaust gas temperature of the boilers used in iron and steel enterprises is also very high. In the past, these high-temperature flue gases were directly discharged to the atmosphere , resulting in a huge waste of resources. At present, in order to save energy, many technologies have been produced to recover the waste heat of this high-temperature flue gas. In the existing technology, the waste heat recovery and utilization facilities usually used are heat exchangers, but Because the flue gas temperature fluctuates violently and the dust content is large, the ordinary water tube waste heat boiler is difficult to be used in the waste heat recovery of boilers used in iron and steel enterprises.
