Abstract
The invention provides a connection structure of a dry dust remover and an air preheater, which reduces the energy consumption of a draught fan, saves the energy and solves the problem of interference of low-temperature corrosion without generating ash deposition and blockage so that equipment achieves high efficiency. The connection structure comprises the dry dust remover, the air preheater and the draught fan. The connection structure is characterized in that an inlet of the air preheater is connected to a flue gas outlet of the dry dust remover, a low-temperature flue gas outlet of the air preheater is connected with the draught fan, and the air preheater specifically is a cast-iron air preheater.
Description
Technical field
The present invention relates to the technical field of structures of Industrial Boiler, be specially the syndeton of dry collector and air preheater.
Background technology
The dry collector of existing boiler, before its air preheater is arranged in the import of dry collector, fouling phenomenon easily takes place in it, thereby increase the energy consumption of air-introduced machine, waste energy, technical at present, add air preheater and be arranged in the dry collector rear portion, then lower flue-gas temperature can produce cold end corrosion to air preheater, makes a little less than its heat-exchange capacity, and then reduces device efficiency.
Summary of the invention
The invention provides the syndeton of dry collector and air preheater, it can not produce the fouling phenomenon, reduces energy consumption, the energy savings of air-introduced machine, and has solved the interference of cold end corrosion simultaneously, makes the device efficiency height.
The syndeton of dry collector and air preheater, it comprises dry collector, air preheater, air-introduced machine, it is characterized in that: the import of described air preheater is connected in the exhanst gas outlet of described dry collector, the low-temperature flue gas outlet of described air preheater connects described air-introduced machine, and described air preheater is specially the cast iron air preheater.
After adopting structure of the present invention, make not fouling of air preheater, reduced energy consumption, the energy savings of back air-introduced machine through the flue gas of relative clean after the dedusting; The cast iron air preheater is highly resistant to the air preheater cold end corrosion in addition, has solved the interference of cold end corrosion, guarantees its heat-exchange capacity, makes the device efficiency height.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises that dry collector 1, cast iron air preheater 2, air-introduced machine (belong to existing mature structure, do not draw among the figure), the import 3 of cast iron air preheater 2 is connected in the exhanst gas outlet 4 of dry collector 1, and the low-temperature flue gas outlet 5 of cast iron air preheater 2 connects air-introduced machine.6 is the gas approach of dry collector among the figure, and 7 is the outlets of cast iron air preheater 2 high temperature airs among the figure, and 8 is the 2 normal temperature air imports of cast iron air preheater among the figure.
