Abstract
The utility model relates to an effective cast air preheater which is composed of an air inlet 1, an air outlet 2, a smoke inlet 3, a smoke outlet 4 and a ribbed tube 6. A jet flow pipe 5 is arranged in the ribbed pipe 6, and the pipe wall of the jet flow pipe 5 is provided with a jet hole 9. Air enters the jet flow pipe 5 through the air inlet 1 and is ejected from the jet hole 9 to impact the inner wall of the ribbed pipe 6 and exchanges heat with smoke. Hot air is output from the air outlet 2. The utility model has the advantages of high heat radiating efficiency, corrosion resistance, wear-resistance and heat energy saving.
Description
The utility model is a kind of air preheater.
At present, adopt the heat exchanger that takes the smoke pre-heating air to adopt flue gas by pipeline, air is by pipeline outer wall fin mode preheated air, and the thermal efficiency is low, waste heat energy.
The purpose of this utility model is that a kind of heat exchange efficiency height will be provided, and is corrosion-resistant, anti abrasive air preheater.
Solution of the present utility model is to install jet pipe in the cast iron gilled tube, and little spray orifice is arranged on the jet pipe, and air impacts the gilled tube inwall by the spray orifice ejection of jet pipe, and flue gas flows through from the gilled tube skin and carries out heat exchange.
The utility model adopts the jet flow enhanced heat exchange, and gilled tube is an ironcasting, has solved the cold end corrosion of general Air Preheater Heating Surface, the heat exchange efficiency height.
Below in conjunction with accompanying drawing the utility model is specified:
Fig. 1 is the utility model partial cutaway diagrammatic sketch;
Fig. 2 is one group of gilled tube schematic diagram;
Fig. 3 is the jet pipe cut-away view.
The utility model is by air inlet 1, and air outlet 2 advances mouth 3, outlet flue 4, and gilled tube 6, brace 7 constitutes, and is equiped with jet pipe 5 in gilled tube 6, and jet pipe 5 is a steel pipe, and spray orifice 9 is arranged on the tube wall.Gilled tube 6 is made by cast iron, on the fin in its outside connecting hole 8 is arranged, and is fixed on the brace 8 by screw, and gilled tube 6 can be installed many groups as required.Hot flue gas enters preheater by advancing mouth 3, flows through by gilled tube 6 skins, discharges from outlet flue 4, and air enters jet pipe 5 from air inlet 1, impacts gilled tube 6 inwalls by spray orifice, and hot-air is from air outlet 2 outputs.
