Vertical boiler with smoke heat exchange device

Abstract

The invention discloses a vertical boiler with a smoke heat exchange device. The vertical boiler comprises a boiler body, a boiler hearth is arranged below an inner cavity of the boiler body, a smoke passage is arranged on the upper portion of the boiler body, the boiler hearth and the smoke passage are communicated through a smoke flue, the smoke heat exchange device is arranged at the top of the boiler and comprises a mazy heat exchange water pipe arranged inside the smoke passage, a smoke flue pipe is distributed between a smoke flue collection cavity and the boiler hearth in a bent manner, radiating fins are arranged on the outer surface of the smoke flue pipe, two groups of arc-shaped spiral pipelines are arranged on the side wall of the inner cavity of the boiler body, and a heat insulating layer is arranged on the surface of the boiler body. Through the smoke flue pipe which is bent and the smoke flue collection cavity which is additionally arranged, utilization rate of heat energy is increased to greatest extent; the arc-shaped spiral pipelines utilize heat energy in the boiler body for heating, so that remaining heat energy is utilized fully, and energy resources are saved to greater extent; the smoke heat exchange device is arranged at the top of the boiler body, so that waste heat of the smoke passage is utilized efficiently, and waste heat of a smoke flue is converted.

Description

technical field [0001] The invention relates to a boiler, in particular to a vertical boiler with a flue gas heat exchange device. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. At present, boilers are widely used in industrial construction and people's daily life middle. But at the same time, the boiler is also a very energy-consuming equipment. With the increasing shortage of energy, the importance of saving energy has become increasingly prominent. Moreover, in existing boiler devices, most of the heat energy can be directly stored or supplied to devices that require heat, but most of the heat discharged from the flue gas channel is discharged into the atmosphere, and the utilization rate of waste heat in the flue gas channel decreases...

Problems solved by technology

Moreover, in existing boiler devices, most of the heat energy can be directly stored or supplied to devices that require heat, but most of the heat discharged from the flue gas channel is discharged into the atmosphere, and the utilization rate of waste heat in the flue gas channel decreases, which affects the thermal efficiency of the boiler. Therefore, it is urgent to develop a device that can efficiently utilize the waste heat of the flue gas channel and convert the waste heat of the flue gas channel to improve the thermal efficiency of the boiler.
