Device includes smoke channel box and more heat exchanger tubes for being horizontally placed on the smoke channel box equipped with gas inlet and exhanst gas outlet, is changed described in more
The both ends of heat pipe pass through tube sheet respectively and are fixed on the tank wall of the smoke box.This air heat exchanger exists such as in use
Lower problem: the dust for being deposited on heat exchange pipe external surface is not easily cleaned；The swelling stress generated after heat exchanger tube expanded by heating easily causes
Tube sheet cracking, to reduce the service life of heat exchanger tube.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of high ash-laden gas waste heat recycling air heat exchanger,
It is easily produced after the easy dust stratification of heat exchanger tube and heat exchanger tube expanded by heating to solve existing high ash-laden gas waste heat recycling air heat exchanger
The problem of raw swelling stress.
The utility model technical scheme applied to solve the technical problem are as follows: this includes being equipped with gas inlet and exhanst gas outlet
Smoke channel box, in the smoke channel box be equipped with the more U-shaped heat exchanger tubes being vertically arranged, the inlet end of the U-shaped heat exchanger tube and go out
Gas end is mounted in the top of the smoke channel box by tube sheet.
In above-mentioned high ash-laden gas waste heat recycling air heat exchanger technical solution, more specific technical solution can be with
Be: the U-shaped heat exchanger tube is vertical setting with the flue gas flow direction in the smoke channel box.
Further: the smoke channel box is equipped with air communication cover, the air inlet of the U-shaped heat exchanger tube in the top of the tube sheet
End is connected with the air intlet of the air communication cover, the sky of the outlet side of the U-shaped heat exchanger tube and the air communication cover
Gas outlet is connected.
Further: the lower section of U-shaped closed end of the smoke channel box in the U-shaped heat exchanger tube is equipped with ash bucket, the ash bucket
It is connect by ash tube with scraper slag removing machine.
Further: the air intlet of the air communication cover is located at the exhanst gas outlet side of the smoke channel box, the sky
The air outlet slit of gas connection cover is located at the gas inlet side of the smoke channel box.
Further: the air outlet slit of the air communication cover is opening up.
By adopting the above-described technical solution, the utility model have the following beneficial effects: 1 compared with prior art, by
In being equipped with the more U-shaped heat exchanger tubes being vertically arranged in smoke channel box, dust deposit has been not easy in U-shaped heat exchange pipe surface；And U-shaped changes
The inlet end of heat pipe and outlet side are mounted in the top of smoke channel box by tube sheet, can seal to its U-shaped after U-shaped heat exchanger tube expanded by heating
Closed end extends, and will not generate swelling stress, improve the service life of U-shaped heat exchanger tube；2, the cigarette in U-shaped heat exchanger tube and smoke channel box
Air-flow can make flue gas transversal flow heat release outside U-shaped heat exchanger tube, air parallel baffled in U-shaped heat exchanger tube to being vertical setting
Heat absorption, heat exchange efficiency are high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the cross-sectional view at the A-A of Fig. 1.
Fig. 3 is the cross-sectional view at the B-B of Fig. 1.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail:
High ash-laden gas waste heat recycling air heat exchanger as shown in Figure 1 includes going out equipped with gas inlet 5-1 and flue gas
The smoke channel box 5 of mouth 5-2, smoke channel box 5 are in horizontally disposed and are installed on the ground by steelframe 2；More are provided in smoke channel box 5 to erect
The U-shaped heat exchanger tube 8 being directly arranged, every U-shaped heat exchanger tube 5 are vertical setting with the flue gas flow direction in smoke channel box 5, U-shaped heat exchanger tube 8
Inlet end and outlet side by tube sheet 7 be mounted in smoke channel box 5 top；Smoke channel box 5 above tube sheet 7 is equipped with air communication
Cover 6, the inlet end of U-shaped heat exchanger tube 8 is connected with the air intlet 6-1 of air communication cover 6, the outlet side of U-shaped heat exchanger tube 8 and
The air outlet slit 6-2 of air communication cover 6 is connected, as shown in Figures 2 and 3；The air intlet 6-1 of air communication cover 6 is located at
The side of the exhanst gas outlet 5-2 of smoke channel box 5, the air outlet slit 6-2 of air communication cover are located at the gas inlet 5-1 of smoke channel box 6
