Abstract
The utility model relates to heat exchanging equipment, comprising a main heat exchanger. The inlet of the main heat exchanger is provided with a front heat exchanger, and the front heat exchanger is connected in series with the main heat exchanger. The utility model can decrease the maintenance cost of the heat exchanger and prolong the service life of the heat exchanger.
Description
The utility model relates to a kind of heat-exchange apparatus.
The drying of various materials such as grain, seed, vegetables, timber, medicine generally adopts hot blast to dry.For coal-fired drying equipment,, all to adopt flue gas-air heat exchanger for fear of the pollution of flue gas to material.Used flue gas-air heat exchanger mainly is a tubular heat exchanger now, and the high-temperature flue gas of combustion furnace and the radiant heat of naked light act directly on the tube sheet and tubulation termination of heat exchanger, heat exchanger tube sheet and tubulation and easy scaling loss.Therefore, the maintenance cost of present flue gas-air heat exchanger is higher, and service life is shorter.
The purpose of this utility model is to provide a kind of maintenance cost low, the flue gas-air heat exchanger of long service life.
The purpose of this utility model is achieved in that it comprises that main heat exchanger is provided with preposition heat exchanger in the porch of main heat exchanger, and preposition heat exchanger and main heat exchanger are in series.
Advantage of the present utility model is: design of heat exchanger is become the two-stage type that is in series by preposition heat exchanger and main heat exchanger, main heat exchanger is not subjected to the infringement of hyperthermia radiation, make the life-span of main heat exchanger improve greatly, preposition heat exchanger volume is relative with heat exchange area less, can adopt special heat proof material manufacturing or carry out special heat-resisting processing, prolong it and use the longevity, and be unlikely whole cost is improved a lot.Preposition heat exchanger volume is little, and replacement cost is lower, so maintenance cost of the present utility model is lower, and long service life.The end cap of preposition heat exchanger can be arranged at the outside, and the replacing of consumable accessory is very convenient.
Fig. 1 is a structural representation of the present utility model:
Fig. 2 is the A-A cutaway view of Fig. 1.
For example the utility model is done more detailed description below in conjunction with accompanying drawing: preposition heat exchanger 2 is set in the porch of main heat exchanger 4.Preposition heat exchanger 2 is the horizontally-arranged tubular heat exchanger, and main heat exchanger also is a tubular heat exchanger, and the tubulation of preposition heat exchanger and the tubulation of main heat exchanger are perpendicular.Preposition heat exchanger volume and heat exchange area are much smaller than main heat exchanger.The end cap of preposition heat exchanger is arranged at the outside.Come from the elevated temperature heat flue gas of combustion furnace and naked light through entering the outside that mouth 1 at first passes the tubulation 3 of preposition heat exchanger 2, heat given with hyperthermia radiation with to streamed exchange come from cold air duct 7, and the cold air that in tubulation 3, flows, exchange is most radiant heat down, after hot flue gas passes preposition heat exchanger, enter the tubulation 5 of main heat exchanger 4, carry out heat exchange with the cold air that enters by cold wind mouth 8, flue gas after the cooling is drawn by outlet flue 6, and heated air is delivered to drying equipment by hot-air mouth 9.
Claims (5)
1, a kind of multi-stag flue gas-air heat exchanger, it comprises main heat exchanger, it is characterized in that: be provided with preposition heat exchanger in the porch of main heat exchanger, preposition heat exchanger and main heat exchanger are in series.
2, multi-stag flue gas-air heat exchanger according to claim 1 is characterized in that: described preposition heat exchanger is the horizontally-arranged tubular heat exchanger, and the tubulation of its tubulation and main heat exchanger is perpendicular.
3, multi-stag flue gas-air heat exchanger according to claim 1 and 2, it is characterized in that: the heat exchange area of preposition heat exchanger is less than main heat exchanger.
