Abstract
The utility model relates to a novel slide pressure film rotating deoxygenating device, which is composed of a deoxygenating tower and a water tank. The utility model is characterized in that the deoxygenating tower is provided with a steam-water separator, a D-shaped film rotating tube, a single-layer grate set, a single-layer detachable filler component and an intumescent steam chamber, the water tank is provided with a plurality of steam injectors and an anti-rotating plate, and a water outlet guide tube of the deoxygenating tower is guided to an outlet of the deoxygenating water tank. Compared with the original old deoxygenating device, the deoxygenating device has the advantages of low manufacturing cost, good stability, high deoxygenating efficiency, strong applicability, etc.
Description
The utility model relates to the improvement of deaeration plant commonly used in a kind of thermal power plant, exactly is the improvement to the proterotype deaeration plant.
Thermal de-aeration is that deoxygenation mode is the most widely adopted in the thermal power plant.Improve feed water quality, reducing to water-soluble oxygen is the important channel that prevents heat power equipment and corrosive pipeline thereof and prolong its service life.The equipment that thermal de-aeration adopts usually has atomizing oxygen-eliminating device and intumescence formula oxygen-eliminating device two major types.Shortcomings such as these two kinds of oxygen-eliminating devices exist all that oxygen removal efficiency is low, volume is big, adaptability, stability are all relatively poor.Also have a kind of film deoxidizer at present,, on problems such as oxygen removal efficiency, adaptability, stability, still have many shortcomings though the more preceding two kinds of oxygen-eliminating devices of the deaerating effect of this oxygen-eliminating device are quite a lot of.
The purpose of this utility model is to provide a kind of novel sliding pressure rotary film oxygen-eliminating device at above-mentioned shortcoming for the user.
The technical solution of the utility model is as follows:
By the sliding pressure rotary film oxygen-eliminating device that oxygen-removing tower and water tank are formed, its technical essential is: A, in the deoxygenation tower body, and a steam-water separator is installed at the steam drain place, top of oxygen-removing tower, and this steam-water separator and body of the tower are welding; In the deoxygenation assembly in the top of deoxygenation tower body, several D type rotation membrane pipes are arranged, this rotation membrane pipe and a deoxygenation assembly are integrally welded; At the oxygen-removing tower middle part one individual layer castor group is installed; Change former filler assembly into one deck by multilayer and also be detachable; Increase an intumescence steam chest at oxygen-removing tower top one sub-assembly by former single hydroecium; Tower body and water tank are directly welded by original macropore and become communicating pipe aperture welding; B, in water tank; The steam that enters oxygen-removing tower is sent into through injector, promptly in the communicating pipe of the bottom of the top of water tank and oxygen-removing tower, several steam jet ejectors are installed, the water outlet of oxygen-removing tower is caused the outlet of deoxygenation water tank through conduit; One anti-rotating plate is installed at water tank outlet place, and it is to insert to be connected with tank box.
After the utility model is realized, overcome the shortcoming that original film deoxidizer exists, advantage such as have that the cost cost is low, good stability, oxygen removal efficiency height, adaptability are strong.
Description of drawings:
Fig. 1 is an overall structure generalized section of the present utility model.1-deoxygenation water tank wherein, 2-oxygen-removing tower, deoxygenation assembly of 3-, the 4-feedwater mixes pipe, 5-steam-water separator, 6-steam discharge (gas) pipe, 7-D type rotation membrane pipe, 8-hydroecium, 9-intumescence air chamber, the 10-steam inlet pipe, 11-castor group, 12-filler group, the 13-steam jet ejector, 14-steam guiding tube, 15-aqueduct, 16-prevents rotating plate, 17-water tank outlet.
Below in conjunction with accompanying drawing the utility model is further specified:
Various feedwater mix pipe (4) (caliber D through the inlet feedwater
n=450) hole of sending on the deoxygenation assembly (3) (φ=133 h=750) after the mixing of chewing is injected with the jet kenel, and after this inside pipe wall eddy flow film forming attitude, flow to the steam that this pipe lower end and intumescence steam chest (9) send to by the hole on the rotation membrane pipe and produce intumescence, and cause heat transfer, the mass transfer area of mist film skirt layer to finish a deoxygenation in the exit of rotation membrane pipe.Water carries out secondary distribution through castor group (11) (φ=3200 h=450) afterwards, then enters filler group (12) (φ=3200 h=450), finishes whole deoxygenations afterwards with after steam that vapor steam blaster (13) is sent to contacts once more.Water after the deoxygenation is through aqueduct (15) (D
n=500) causing the outlet pipe (17) that anti-rotating plate (16) are housed locates, and send into entrance of water-supplying pump, the oxygen-eliminating device abrupt pressure reduction caused the entrance of water-supplying pump vaporization when so not only having guaranteed deaerating effect but also having prevented removal of load, and can reduce invalid water level, increased water tank and used volume.Heating steam divides two pipelines, one from water tank upper through steam guiding tube (14) (D
n=300) steam jet ejector (13) is sent into oxygen-removing tower (2) bottom, through filler group (12), castor group (11) and D type rotation membrane pipe (7) fully with feed water conduct heat, remnants mixing gas behind the mass transfer after the steam-water separator (5) on oxygen-removing tower top separates, drain in the air by gland steam exhauster (6).The steam inlet pipe (10) that another steam pipe causes on the deoxygenation assembly (3) enters intumescence vaporium (9), as the usefulness of intumescence deoxygenation.
