Description
Technical field: the utility model relates to Oxygen Removal Technology for Boiler Feedwater, mainly is meant a kind of no tower film deoxidizer.
Background technology: large-sized station boiler and Industrial Boiler are for preventing corrosion, its feedwater all needs to handle through deoxygenator, at present, deaerating effect is preferably the heating power membrane deaerator, mostly structural form is to be provided with vertical deoxygenation head (or claiming oxygen-removing tower) on horizontal water tank, its body is tall and big, and it is big to take up space, the cost of manufacture height, shock resistance is poor.For this reason, develop a kind of no tower membrane deaerator that water tank and deoxygenation head are united two into one at present, China utility model patent ZL99205986 discloses this deoxygenator, the part but it still comes with some shortcomings, the one, the steam diversion device is only established a cover, technical requirements when not satisfying the deoxygenator startup, the 2nd, the steam jet pipe that inserts under water is in line form, make the inequality of vapour-liquid heat exchange under water, deoxygenation is undesirable, and the 3rd, do not have water inlet and mix pipe, make the water temperature that enters the rotation membrane pipe hydroecium, the pressure inequality, fluctuation is big, the 4th, the rotation membrane pipe bottom does not have steam spray vapour device, only depend on and spray steam and the exchange of water membrane skirt caloic that vapour is overflowed under water, temperature is low, and moisture film heats up slow, it is not enough to heat up, and deaerating effect is poor.
Goal of the invention: the purpose of the utility model, be to overcome the deficiency that has no tower membrane deaerator now, a kind of novel no tower film deoxidizer is provided.
The utility model is enforcement like this, novel no tower film deoxidizer, comprise horizontal deoxygenation water tank 1, the steam diversion device that is connected with the steam-in is arranged in the deoxygenation water tank, the rotation membrane pipe hydroecium 17 that is connected with water-in, rotation membrane pipe hydroecium top is provided with water separator 16, deoxygenation water tank bottom one end is provided with water outlet 22, the steam diversion device comprises operation steam diversion device 4 and starts steam diversion device 5, operation steam diversion device comprises horizontal isocon 7 and with different angles insertion steam jet pipe 8 under water, starts the steam diversion device and comprise the horizontal isocon 9 and the oblique insertion steam jet pipe 10 under water that is arranged in parallel; Establish water inlet between admission port and the rotation membrane pipe hydroecium 17 and mix pipe 15; Rotation membrane pipe hydroecium bottom has the choker-line air jet system, and it comprises female arm 21 and steam nozzle 20, and the steam nozzle is corresponding one by one with the rotation membrane pipe end opening.
The utility model has the advantages that, establish two and overlap independently steam diversion device, improve steam supply situation when starting, heating up rapidly reaches the best oxygen condition that removes; The steam jet pipe that is picked out by isocon makes the vapour of different azimuth spray under water even with the insertion of different angles under water, forms dynamic disturbance state under the liquid, heats up evenly, does not stay the dead angle, and deoxygenation is abundant; Set up the into mixed pipe of water before the rotation membrane pipe hydroecium, make the multi-source feedwater give mixing, make the water temperature, the pressure that enter the rotation membrane pipe hydroecium steadily even, in order to deoxygenation; Choker-line spray vapour device is set up in rotation membrane pipe hydroecium bottom, makes the direct and rotary film water skirt effect from the steam of female pipe, quick heating, and deaerating effect is good.
Description of drawings:
Accompanying drawing 1 the utility model structure iron
Accompanying drawing 2 the utility model A-A sectional views
Accompanying drawing 3 the utility model B-B sectional views
Embodiment: shown in accompanying drawing 1 the utility model structure iron, deoxygenation water tank 1 is horizontal tank body, double water storage and deoxygenation dual function, startup is set in the case independently and moves two cover steam diversion devices, operation steam diversion device 4 comprises the horizontal isocon 7 that is connected with operation steam-in 2, and, being distributed with micropore 6 on the steam jet pipe tube wall by many steam jet pipes 8 that isocon picks out, the oblique insertion that steam jet pipe becomes different angles is under water.Start the horizontal isocon 9 that steam diversion device 5 comprises and startup steam-in 3 is connected, and many steam jet pipes 10 that pick out by isocon, be arranged in parallel oblique insertion under water, see accompanying drawing 2 and 3, steam jet pipe becomes different angles different azimuth ground to arrange under water, the vapour-liquid collision is even, and dynamic under water disorderly heat exchange is abundant, strengthens deaerating effect.
An end top is provided with rotation membrane pipe hydroecium 17 in the case, is the cylinder that a steel plate is welded into, in the cylinder with about two horizontal baffles be sealed to a hydroecium, rotation membrane pipe 19 and communicating pipe 18 are passed two dividing plates.Rotation membrane pipe hydroecium top deaerated water tank wall is established a water separator 16.
Rotation membrane pipe hydroecium inlet connects the mixed pipe 15 of a water inlet, and condensed water, supplementary feed, hydrophobic, the hydrophobic feed-water intake 11,12,13,14 that connects respectively of warm-air drier of drainage pump enter the into mixed pipe of water, is exported by the mixed pipe of water inlet to connect rotation membrane pipe hydroecium inlet.
The rotation membrane pipe hydroecium is divided into throttling spray vapour device, on female arm 21 that horizontal steam diversion pipe is connected, be provided with a plurality of steam nozzles 20, the steam nozzle is corresponding one by one with the rotation membrane pipe end opening, the steam of ejection directly contacts with the collision of rotation membrane pipe intumescence water membrane skirt, be warming up to temperature of saturation rapidly, steam also rises along the rotation membrane pipe internal chamber wall simultaneously, revolves membrane mass transfer with internal chamber wall water and conducts heat.
Remove oxygen: the fs, condensed water, supplementary feed, hydrophobicly mix pipe through intaking and enter the rotation membrane pipe hydroecium, form water membrane skirt through rotation membrane pipe, finish heat and mass transfer process most important, that load is maximum with the steam that the ejection of steam nozzle is risen, dissolved oxygen in the water is overflowed with the small bubbles form more than 90%, finishes the fs deoxygenation.Subordinate phase, be that feedwater reaches below the liquid level, utilize the shunting steam jet pipe to carry out the deoxygenation second time, feedwater is entered by the top of water tank one end, flow out from the bottom of the other end, path length in water tank, the time is long, carries out thermal exchange at the steam that ejects with steam jet pipe all the time, oxygen is overflowed, flow to water tank rotation membrane pipe hydroecium end with steam, rise through rotation membrane pipe and communicating pipe, after outside the water separator discharge case.
