Embodiment Construction

[0009] according to Figure 1-2 The specific structure of the present invention will be described in detail. The structure of the countercurrent heat exchange energy saving and environmental protection pyrotechnic tube atmospheric pressure boiler is as follows: Figure 1-2 shown. It consists of a furnace 1, an upper pyrotechnic tube 2, a lower pyrotechnic tube 3, a pot shell 4, and a tube plate 5. The high-temperature flue gas of the second pass passes through the upper pyrotechnic tube 2 in the pot shell for heat exchange, and then the lower flue gas of the third pass passes through the lower pyrotechnic tube 3 in the pot shell. After heat exchange, the flue gas is discharged out of the boiler body, completely changing the original downstream heat exchange method, realizing countercurrent heat exchange to save energy; reducing carbon dioxide emissions; adopting normal pressure design to reduce steel consumption, achieving energy saving and environmental protection purposes ...

Abstract

The invention relates to a counter current heat exchanging smoke-fire constant pressure boiler capable of saving energy and protecting the environment, which makes use of the counter current heat exchanging principle and comprises a boiler furnace, an upper smoke-fire tube, a lower smoke-fire tube, a boiler shell and a tube sheet, wherein high-temperature flue gas with two return trips firstly passes through a position with higher water temperature at the water side of the upper smoke-fire tube in the boiler shell for exchanging heat, then lower-temperature flue gas with three return trips passes through a position with lower water temperature at the water side of the lower smoke-fire tube in the boiler shell for exchanging heat. The flue gas is discharged out of the boiler body after the heat exchange; the original downstream heat exchanging means is completely changed; counter current heat exchange is realized; energy sources are saved; and carbon dioxide emission is reduced; as the constant pressure design is adopted, steel consumption is reduced, and the purposes of saving energy and protecting the environment are achieved; and the counter current heat exchanging smoke-fire constant pressure boiler can be produced by adopting a normal boiler production technology.

Description

technical field [0001] The invention relates to the design and manufacturing technology of a pyrotechnic tube atmospheric boiler, in particular to a countercurrent heat exchange, energy saving and environment-friendly pyrotechnic tube atmospheric boiler. technical background [0002] At present, the commonly used pyrotechnic tube atmospheric pressure boiler is composed of furnace, upper pyrotechnic tube, lower pyrotechnic tube, pot shell and tube plate. The surface is one return pass; the high temperature flue gas heat exchange surface is two return passes; the low temperature flue gas heat exchange surface is three return passes, and the low temperature flue gas is discharged out of the boiler body after heat exchange. The furnace of the pyrotechnic tube atmospheric boiler widely used now is used as the radiation heat exchange surface of the combustion chamber. The part with lower water temperature on the water side of the pyrotechnic tube in the lower part of the pot shel...
