Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1-3, a kind of hydrogen peroxide concentration unit falling film evaporator annular steam distributor, divide including annular steam
Cloth device shell body 5, annular steam distributor inner housing 6 and equipment outer simplified 4, annular steam distributor shell body 5 and annular are steamed
Vapour distributor inner housing 6 connects formation annular steam distributor, being internally provided with outside equipment of annular steam distributor shell body 5
Simplified 4, the inwall of equipment outer simplified 4 is fixing with the surface of annular steam distributor inner housing 6 to be connected, outside annular steam distributor
The top of housing 5 is fixedly connected with falling film evaporator upper perforated plate flange 8, and the side of falling film evaporator upper perforated plate flange 8 is fixing even
Being connected to evacuated tube 7, the side of annular steam distributor shell body 5 is fixedly connected with steam inlet 9, annular steam distributor inner shell
Being fixedly connected with deflection plate 3 on the inwall of body 6, deflection plate 3, as the term suggests being used to change the plate that fluid flows to, is usually used in shell
Formula design of heat exchanger shell side medium runner, according to medium character and flow and heat exchanger size determine deflection plate 3 number, folding
Stream plate 3 is arranged on shell side, and it both can improve heat-transfer effect, also acts as the effect supporting tube bank, and the quantity of deflection plate 3 has two
Individual, and two deflection plates 3 lay respectively at the first half and the lower half of annular steam distributor inner housing 6, on deflection plate 3 fixing even
Being connected to heat exchanger tube 10, heat exchanger tube 10 is one of element of heat exchanger, within being placed in cylinder, and the friendship of heat between two media
Changing, the two ends of heat exchanger tube 10 are fixed be connected with falling film evaporator upper perforated plate flanges 8 and falling film evaporator lower perforated plate flange 11 respectively,
Falling film evaporator heat exchanger steam fixed gas exports cancels several heat exchanger tubes 10 near 2 positions, be allowed to enough separated spaces,
To reduce resistance when taking out fixed gas, the side of falling film evaporator lower perforated plate flange 11 is fixedly connected with and drains mouth 12, and falling liquid film steams
Sending out device lower perforated plate flange 11 and be fixedly connected on the bottom of equipment outer simplified 4, the side of equipment outer simplified 4 has been respectively fixedly connected with steaming
Vapour condensate drain outlet 1 and fixed gas outlet 2, the position of steam condensate (SC) floss hole 1 is higher than the position draining mouth 12, and steam is cold
Solidifying water outlet 1 and fixed gas export 2 positions and arrange the most from top to bottom, and fixed gas outlet 2 is arranged on annular steam distributor
The lower section of inner housing 6 lower half deflection plate 3, when preventing vacuum from extracting out, steam walks short circuit, and steam enters vapour structure and significantly slowed stream
Speed and the deposition of steam, make to add distribution of steam uniform, and steam flow rate is the lowest, thus exchanges stress and impact produced by heat pipe 10
Being substantially reduced, the corrosion that heat exchanger tube 10 produces because of vapor deposition and the formation on inside pipe wall film affect the least, meanwhile, and annular
Steam distributor also plays a part heat exchanger expansion joint, thus improves evaporation efficiency, decreases steam consumption, thus improves
In the service life of equipment, yield have also been obtained raising further, and this distributor makes steam homogeneous heating, flow velocity is low, heat exchanging
Pipe 10 impacts little, and steam energy consumption reduces further, is especially suitable for the distribution of steam of hydrogen peroxide concentration unit falling film evaporator.
In sum, this hydrogen peroxide concentration unit falling film evaporator annular steam distributor, steam enters vapour structure and significantly subtracts
Having delayed the deposition of flow velocity and steam, made to add distribution of steam uniform, steam flow rate is the lowest, thus exchanges stress produced by heat pipe 10
Being substantially reduced with impact, the corrosion that heat exchanger tube 10 produces because of vapor deposition and the formation on inside pipe wall film affect the least, with
Time, annular steam distributor also plays a part heat exchanger expansion joint, thus improves evaporation efficiency, decreases steam consumption,
Thus improve the service life of equipment, yield have also been obtained raising further.
During use, steam, after steam inlet 9 is come in, through annular chuck distribution, goes out chuck from the upper end overflow of chuck, enters
Entering heat exchanger tube 10 top, walk S route from top along deflection plate 3, a part of condensed water is drained along steam condensate (SC) floss hole 1, separately
A part of fixed gas is taken away from fixed gas outlet 2 by vacuum pump.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, permissible
Understand and these embodiments can be carried out multiple change without departing from the principles and spirit of the present invention, revise, replace
And modification, the scope of the present invention be defined by the appended.
