Improvement as the utility model: the chimney heat exchanger is three backhaul horizontal tube bundle chimney heat exchangers, along air
Three groups of horizontal tube bundles are equipped in the direction of travel of shell side, is equipped in the two sides of tube bank and connects the tube side head and the tail of three groups of horizontal tube bundles
Form the connection smoke box of three backhaul flue gas flow channels.
As further improvement of the utility model: the hot wind mixing chamber is using chimney heat exchanger shell side center line as axis
Symmetrical T shape hot wind mixing chamber is equipped with symmetrical two heat on the wall in front of the shell-side outlet of chimney heat exchanger
Wind delivery outlet is equipped in hot wind mixing chamber and is located at chimney heat exchanger shell side center with T shape windbreak, the vertical wall of T shape windbreak
No more than two hot winds of cross wall length of line, T shape windbreak export pitch of holes.
Further improvement as the utility model: the heat exchange of every group of tube bank is constituted in the direction of travel of shell side along air
The number of pipe increases step by step.
The utility model has the advantages that the grain drying tower warm air oil furnace of the utility model includes oil due to using the hot-blast stove
Burner and chimney heat exchanger, the chimney heat exchanger are horizontal tube bundle chimney heat exchanger, and the tube side of chimney heat exchanger exports warp
Air-introduced machine runs in sky chimney, hot wind mixing chamber is equipped in the shell-side outlet of chimney heat exchanger, in oil burner and chimney heat exchanger
Tube-side inlet between be equipped with flame-out room, be equipped with the flame-out wall vertical with oil burner flame injection direction in flame-out room, put out
Wall with flues will penetrate that direction has been separated out fiery room and without fiery room, the flame-out wall is the flower hole constructed by refractory brick along flame in flame-out room
Flame-out wall, work is arranged by the way that flame-out room is arranged between oil burner and chimney heat exchanger in the technical solution of wall in flame-out room
When making, the flame end ejected by oil burner is thoroughly extinguished after slightly meeting flower hole wall, so that there was only high-temperature flue gas without fiery room and not having
There is flame, flame can be effectively prevented and enter in the heat exchanger tube of chimney heat exchanger, burns heat exchanger tube, also, press from both sides in high-temperature flue gas
The tar of band can condense in flame-out wall and flame-out room, so that the coking in heat exchanger tube is prevented, therefore, the grain of the utility model
Drying tower has structure simple with warm air oil furnace, and occupied area is small, starts the advantages that speed is fast, flue heat exchange in use process
In the heat exchanger tube of device will not coking, the long service life of heat exchanger tube.Due to using the chimney heat exchanger as three backhauls level
Chimney heat exchanger is restrained, the direction of travel along air in shell side is equipped with three groups of horizontal tube bundles, is equipped in the two sides of tube bank by three groups
The tube side head and the tail connection of horizontal tube bundle forms the technical characteristic of the connection smoke box of three backhaul flue gas flow channels, increases flue gas flow channel
Length enables high-temperature flue gas sufficiently to exchange heat in tube side with the air of shell side, and capacity usage ratio is higher, and energy-saving effect is more preferable.
Due to use the hot wind mixing chamber be using chimney heat exchanger shell side center line as the symmetrical T shape hot wind mixing chamber of axis,
It is equipped with symmetrical two hot wind delivery outlets on the wall in front of the shell-side outlet of chimney heat exchanger, is set in hot wind mixing chamber
Have and be located at chimney heat exchanger shell side center line with T shape windbreak, the vertical wall of T shape windbreak, the cross wall length of T shape windbreak is little
In the technical characteristic of two hot wind output pitchs of holes, allow the grain drying tower warm air oil furnace of the utility model from two
The hot wind that a hot wind delivery outlet steadily exports hot wind, and exported exports again after forming sinuous flow samming in mixing chamber, temperature
Degree fluctuation is smaller, is more advantageous to and is precisely controlled grain heat-drying process, the grain quality dried out is more preferable.
Detailed description of the invention
The grain drying tower of the utility model is described in further detail with warm air oil furnace with reference to the accompanying drawing.
Fig. 1 is the mansion view structural schematic diagram of the grain drying tower warm air oil furnace of the utility model.
Specific embodiment
As shown in Figure 1, the grain drying tower warm air oil furnace of the utility model, including oil burner 13 and flue heat exchange
Device 4, the chimney heat exchanger are horizontal tube bundle chimney heat exchanger, and the tube side outlet 2 of chimney heat exchanger is run in sky cigarette through air-introduced machine
Chimney 1, chimney heat exchanger shell-side outlet 7 be equipped with hot wind mixing chamber 8, the tube-side inlet of oil burner and chimney heat exchanger it
Between be equipped with the flame-out room 12 of connection oil burner and chimney heat exchanger, be equipped in flame-out room and oil burner flame injection direction
Vertical flame-out wall 11, flame-out wall will penetrate direction along flame in flame-out room and be separated out fiery room 14 and without fiery room 10, described flame-out
Wall be constructed by refractory brick, high-temperature flue gas can by Hua Dongqiang.The hot wind mixing chamber is with chimney heat exchanger shell side
Center line is the symmetrical T shape hot wind mixing chamber of axis, and left and right pair is equipped on the wall in front of the shell-side outlet of chimney heat exchanger
The two hot wind delivery outlets 9 claimed are equipped with and T shape windbreak 15, T shape windbreak and T shape hot wind mixing chamber in hot wind mixing chamber
Symmetrical overlapping of axles, contrary, the vertical wall 16 of T shape windbreak is located at chimney heat exchanger shell side center line, the cross of T shape windbreak
No more than two hot winds of wall length a export pitch of holes b.
Preferably, the chimney heat exchanger be three backhaul horizontal tube bundle chimney heat exchangers, along air shell side traveling
Direction is equipped with three groups of horizontal tube bundles 5, is equipped in the two sides of tube bank the tube side head and the tail connection of three groups of horizontal tube bundles forming three backhauls
Two connection smoke boxes 6 of flue gas flow channel.Direction of travel tube side flow area of three groups of horizontal tube bundles along air in shell side increases step by step
Add, that is, the number for constituting the heat exchanger tube of every group of tube bank increases step by step, so that flow velocity and temperature of the high-temperature flue gas in tube side
It is inversely proportional, is more advantageous to high-temperature flue gas and exchanges heat with air, air is more preferable to the heat absorption effect of high-temperature flue gas.
When work, between heat exchanger tube of the cool ambient air by the entrance tube bank of shell side inlet 3 of chimney heat exchanger, edge and heat exchanger tube
Vertical direction is advanced, and is exchanged heat with the high-temperature flue gas of tube side (in heat exchanger tube), is heated to form after hot wind from chimney heat exchanger
