Fixed head 1, finned tube 2, liquid collecting room 3, steam chest 4, U type connecting leg 5, water inlet take over 6, go out that vapour takes over 7, stationary pipes 8, fixed support plate 9, a kind of u pattern heat exchanger, comprises that fixed head 1, finned tube 2, liquid collecting room 3, steam chest 4, U type connecting leg 5, water inlet are taken over 6, gone out that vapour takes over 7, exhaust outlet 8, discharge outlet 9, stationary pipes 10, fixed support plate 11; Air inlet 10, gas outlet 11 and box type heat exchanger 12.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model U type finned heat exchanger is further specified:
A kind of U pattern finned heat exchanger comprises many finned tubes, U type connecting leg, water inlet adapter and goes out vapour and takes over; Except the head end of first finned tube and the tail end of last root finned tube, each root finned tube connects by U type connecting leg head and the tail successively, and the head end of first finned tube connects water inlet to be taken over, and the tail end of last root finned tube connects vapour and takes over.
The head end of described first finned tube and water inlet are connected with liquid collecting room between taking over; The tail end of last root finned tube and go out vapour and be connected with steam chest between taking over.
Comprise fixed head and fixed support plate; Be drilled with the tubulation hole on the fixed head, each root finned tube is through in the respective column pore, and fixed head is positioned at the top of each root finned tube pipe shaft; Be drilled with the tubulation hole on the fixed support plate, each root finned tube is through in the respective column pore, and fixed support plate is positioned at the bottom of each root finned tube pipe shaft.
Comprise stationary pipes, stationary pipes is the bottom of finned tube pipe shaft fixedly; Stationary pipes is connected on the fixed support plate.
With reference to figure 2, fixed head 1 is used for fixing finned tube 2, is drilled with the tubulation hole of some on the fixed head 1, and fixed head 1 is passed on finned tube 2 tops, and fixed support plate 9 is passed in the bottom.Fixed head 1 top is collection chamber at night 3, steam chest 4, and the two is at same height.The adapter at the top of collection chamber 3 at night and steam chest 4 is respectively into water and takes over 6 and go out vapour to take over 7, two height and position be identical.After finned tube 2 passed fixed head 1, the collection chamber at night 3 and the steam chest 4 on itself and top all welded, with fixed installation.In finned tube 2 bottoms, by stationary pipes 8 finned tube 2 is fixed, to avoid blowing of wind, produce the ring of shake and phoenix.On the fixed support plate 9, perforate is used to pass finned tube 2, and stationary pipes 8 is fixed and located.Fixed head 1 and fixed support plate 9 be because after utility model adopts finned tube, and the common high temperature resistant carbon steel sheet of its thickness and material selection is controlled at below the 0.2MPA and gets final product bearing pressure.Collection chamber 3 at night and steam chest 4 are taked plain boiler tube, and design pressure is used and got final product again.Finned tube 2 is taked the ratio-frequency welding mode, good effect of heat exchange, and coefficient of heat transfer height, the pipe quality is also guaranteed.
With reference to figure 1, the operation principle of the utility model U type finned heat exchanger is, the High Temperature Gas that chemical reaction generates adopts heat exchanger to carry out cooling processing by cooling medium usually, and heat exchanger abbreviates gas cooler as, and cooling medium takes water to carry out; All there is 4-6 group single-set heat exchange (box type heat exchanger 12) general gas cooler inside, and it all is up and down fixedly bobbin carriage and tube sheet that single-set heat exchange is taked; Now the last 2-3 group of this 4-6 single-set heat exchange is adopted this U type finned heat exchanger, cooling water is taken over from water inlet and is entered, distribute to collection chamber at night, distribute to enter in the finned tube, carry out heat exchange with high-temperature gas, the water after the heat exchange has part can become gas phase, steam in the heat exchanger tube is mixed in the collector tube and compiles, after compiling by collector tube, go out from venthole, and enter in the collecting device of steam and water; After reaction generation gas cools off through rear end U type heat exchanger heat exchange, enter the rear end operation, but in the heat transfer process of rear end, general cooler inlet segment endways runs into the phenomenon of condensation and dewfall, can cause the accumulation corrosion like this, and this heat exchanger is because bottom design becomes the u type, so just do not have the dewfall accumulation, cause the serious harm of 2 corrosion, and because bottom U type does not have soldered, the hidden danger of having avoided device interior to reveal more, heat exchange can normally be carried out.
