Abstract
Provided is a tube / cast iron plate combined type air pre-heater. The tube / cast iron plate combined type air pre-heater comprises a tube bundle type pre-heater and a cast iron plate type air pre-heater. The tube bundle type pre-heater is arranged above the cast iron plate type air pre-heater. A flue gas outlet of the tube bundle type pre-heater is connected with a flue gas inlet of the cast iron plate type air pre-heater in a sealed mode. An air outlet of the cast iron plate type air pre-heater is connected with an air inlet of the tube bundle type pre-heater through a reset air duct. According to the tube / cast iron plate combined type air pre-heater, advantages of the tube bundle type pre-heater which is mature in technology, simple in structure, low in cost and the like are adopted, and advantages of the cast iron plate type air pre-heater which is corrosion-resistant, not easy to cover by ash are adopted. The tube / cast iron plate combined type air pre-heater has both advantages of the two kinds of pre-heaters, makes up for deficiencies of each pre-heater, performance-cost ration is high, and comprehensive performance is outstanding.
Description
Technical field
The technical program belongs to heat exchange device technical field, specifically a kind of tubulation/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 tubulation/cast iron plate Combined air preheater, and is specific as follows:
A kind of tubulation/cast iron plate Combined air preheater, comprise bundled tube preheater and cast iron plate-type air preheater, described bundled tube preheater is above cast iron plate-type air preheater, and the exhanst gas outlet of bundled tube 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 bundled tube preheater.
Like this, the gas approach of bundled tube 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 bundled tube 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 bundled tube 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 bundled tube preheater and the gas approach of cast iron plate-type air preheater.
The technical program forms an integrated air preheater by bundled tube and cast iron plate-type air preheater.Bundled tube is placed on top, and cast iron plate-type air preheater is placed on the bottom.Flue gas is introduced into the bundled tube 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 bundled tube 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 bundled tube air preheater is heat exchanger tube, heat exchange device in cast iron plate-type air preheater is cast iron fin heat exchanger plates, this air preheater has utilized the advantages such as the bundled tube Air Preheater Technology is ripe, 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.
Description of drawings
Fig. 1 is the structural representation of this preheater;
In figure, the gas approach 3 of bundled tube preheater 1, cast iron plate-type air preheater 2, bundled tube preheater, the exhanst gas outlet 4 of cast iron plate-type air preheater, flange arrangement 5, transfer air channel 6, heat exchanger tube 7, cast iron fin heat exchanger plates 8, the air intlet 9 of cast iron plate-type air preheater, the air outlet slit 10 of bundled tube preheater.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the technical program is described as follows:
A kind of tubulation/cast iron plate Combined air preheater, comprise bundled tube preheater and cast iron plate-type air preheater, described bundled tube preheater is above cast iron plate-type air preheater, and the exhanst gas outlet of bundled tube 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 bundled tube preheater.Like this, the gas approach of bundled tube 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 bundled tube 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 bundled tube 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 bundled tube preheater and the gas approach of cast iron plate-type air preheater.
