Abstract
A turbolator and cast iron plate combined type air pre-heater comprises a turbolator type air pre-heater and a cast iron plate type air pre-heater. The turbolator type air pre-heater is arranged at the upper side of the cast iron plate type air pre-heater. An exhaust gas outlet of the turbolator type air pre-heater is connected with an exhaust gas inlet of the cast iron plate type air pre-heater in a closed mode. An air outlet of the cast iron plate type air pre-heater is connected with an air inlet of the turbolator type air pre-heater through a connecting air flue. The turbolator type air pre-heater has the advantages of being mature in technology, simple in structure, low in construction cost and the like, and the cast iron plate type air pre-heater has the advantages of being resistant to corrosion and not prone to accumulating dust, the turbolator and cast iron plate combined type air pre-heater has the advantages of being capable of combining the advantages of the two air pre-heaters and overcoming the defects of the two air pre-heaters, high in performance cost ratio and excellent in combination property.
Description
Technical field
The technical program belongs to heat exchange device technical field, specifically a kind of turbolator/cast iron plate Combined air preheater.
Background technology
All to adopt the heat exchanger tube of a type in air preheater of the prior art.The physical characteristic of the diverse location due to flue gas/air in preheater is different, so can't accomplish that most economical mode carries out heat exchange.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of turbolator/cast iron plate Combined air preheater, and is specific as follows:
A kind of turbolator/cast iron plate Combined air preheater, comprise flow-disturbing minor preheater and cast iron plate-type air preheater, described flow-disturbing minor preheater is above cast iron plate-type air preheater, and the exhanst gas outlet of flow-disturbing minor preheater is connected with the gas approach of cast iron plate-type air preheater is airtight; The air outlet slit of described cast iron plate-type air preheater is connected by the air channel of transferring with the air intlet of flow-disturbing minor preheater.
Like this, the gas approach of flow-disturbing minor preheater is as the gas approach of Combined air preheater, and the exhanst gas outlet of cast iron plate-type air preheater is as the exhanst gas outlet of Combined air preheater.
The exhanst gas outlet of described flow-disturbing minor preheater is connected by flange arrangement is airtight with the gas approach of cast iron plate-type air preheater.
The framework of the smoke outlet of described flow-disturbing minor preheater, and the framework at the gas approach place of cast iron plate-type air preheater is identical.
Be provided with sealing gasket between the faying face of the exhanst gas outlet of flow-disturbing minor preheater and the gas approach of cast iron plate-type air preheater.
The technical program forms a Combined air preheater by turbolator air preheater and cast iron plate-type air preheater.The turbolator air preheater is placed on top, and cast iron plate-type air preheater is placed on the bottom.Flue gas is introduced into the turbolator air preheater, then enters cast iron plate-type air preheater, then discharges by the cold flue gas exit passageway; Air is introduced into the cast-iron plate type preheater, then enters the turbolator air preheater by the air channel of transferring, and then discharges by the hot air outlet passage.The two kinds of air preheaters in up and down all respectively carry framework, and the frame structure consistent size can be assembled easily.Two kinds of preheaters combine between the higher and lower levels and are provided with sealing gasket between face, connect with flange bolt, facilitate inspection and maintenance.
Heat exchange device in prior art in the turbolator regenerative air heater is the turbolator finned tube, heat exchange device in cast iron plate-type air preheater is cast iron fin heat exchanger plates, the advantages such as this air preheater has utilized turbolator regenerative air heater technology maturation, simple in structure, cost is low, corrosion-resistant, the advantage that is difficult for dust stratification of cast iron plate-type air preheater have been utilized, Combined air preheater has been taken into account the advantage of two kinds of preheaters, made up weak point separately, cost performance is high, excellent combination property.My company's extensive use in actual applications.
