Abstract
Disclosed is a novel rotary film type deaerating device and deaerating method special for a power station. A rotary film type deaerator is a most novel thermal force type deaerator. The rotary film type deaerating device special for the power station mainly comprises a deaerating tower head, a deaerating water tank, connection pipes and outer connection parts, and the deaerating tower head and the deaerating water tank are two large parts. The main part deaerator is composed of a shell, a novel rotary film device, a water spraying grate, a thermal storage filler liquid-steam net and the like. Although an old-fashioned deaerator heats water and extracts oxygen, the proportion of the oxygen is larger than that of heating steam, and the fact that part of the oxygen is further brought into the water tank by downward-flowing water is also a cause of the poor deaerating effect. The novel rotary film type deaerating device special for the power station comprises a rotary film deaerating tower (2) which is connected with the rotary film deaerating water tank (1). The rotary film deaerating water tank is connected with a water sealing cylinder (3), a support seat (4), an electrode point water level gauge (7) and a magnetism rolling board water level gauge (6). The deaerating device is specially applied to the power station.
Description
technical field:
the present invention relates to a kind of new power plant Special rotary membrane type deaerating plant and deoxidation method, the oxygen dissolved in removing boiler feedwater and other gas, prevent corrosion and the heat transfer deterioration of boiler plant and pipeline, ensures heat power equipment safety, run economically.
background technology:
rotating-film deaerator, it is a kind of latest model thermal deaerator, rotating film type deoxygenation is special primarily of deoxygenation tower head, the large part of deoxygenation water tank two and adapter and external piece composition, and its critical piece oxygen-eliminating device (deoxygenation tower head) is made up of parts such as shell, Novel rotary film device (rotating-film tube), trickle double-edged fine-toothed comb, accumulation of heat filler liquid-steam web.Though old-fashioned oxygen-eliminating device heated water and isolated oxygen, oxygen proportion is greater than heating steam, and part oxygen is entered water tank by dirty water-band again, is also a kind of reason causing deaerating effect difference.
summary of the invention:
the object of this invention is to provide a kind of new power plant Special rotary membrane type deaerating plant and deoxidation method.
above-mentioned object is realized by following technical scheme:
a kind of new power plant Special rotary membrane type deaerating plant, its composition comprises: rotary film scavenge oxygen tower, and described rotary film scavenge oxygen tower is connected with rotary film scavenge oxygen water tank, and described rotary film scavenge oxygen water tank is connected with water seal cylinder, bearing, electrode points water-level gauge, magnetic turnover panel water-level gauge respectively.
described new power plant Special rotary membrane type deaerating plant, described rotary film scavenge oxygen tower is connected with exhaust outlet, hand-hole, the supply mouth of a river, top heating steam mouth, bottom heating steam mouth, the mouth of a river of condensing, HP heater drainage mouth respectively.
described new power plant Special rotary membrane type deaerating plant, described rotary film scavenge oxygen water tank exports with relief valve port, steam equalizing pipe, deaerated water tank inlet, water balance pipe, deaerated water respectively, water pump water return outlet is connected,
described new power plant Special rotary membrane type deaerating plant.Described rotary film scavenge oxygen tower is welded into punching press ellipsoidal head by stack shell.
new power plant Special rotary membrane type deaerating plant described in utilization carries out the method for deoxygenation, the described rotary film scavenge oxygen tower condensation mouth of a river adds condensate water and supplementing water enters deoxygenation head inward turning film device group hydroecium, from the little hole deviation churning of rotation membrane pipe to inwall under the pressure of 0.2MPa, form jet, because endoporus is filled with the heating steam of rising, a large amount of heating steam is just inhaled and is involved in by water in jet motion, stroke very little in very short time produces violent Hybrid Heating effect, water temperature significantly promotes, and the water rotated from up to down continues backspin along rotation membrane pipe inner hole wall, form the water membrane skirt that one deck paper is equally thin, rotary diaphragm and heating steam heat exchange abundant, now heat transfer water mass transfer effect is the most desirable, water temperature reaches capacity temperature. and namely oxygen be separated.
beneficial effect of the present invention: 1. the present invention to unit load change adaptable, the oxygen-eliminating device of especially thermal power plant unit and sliding pressure operation has more superiority, can exceed power 50% and run, and dissolved oxygen reach ministry standard.2. the present invention is in addition to vapour, water separate mesh, rotation membrane pipe appearance and size, skinning angle, and packing layer etc. pass through actual motion, constantly accumulate experience, learn from other's strong points to offset one's weaknesses, use current structure more perfect, eliminate deaerator exhaust band water in the past, filler come off, the defect such as oxygen-removing tower vibration.3. stable, shockproof.Be applicable to negative pressure startup, sliding pressure operation, reduce or remit the artificial numerous and diverse adjustment operation in start-up and operation.4. conformability is good, requires outside the advantage such as not harsh to water quality, water temperature, and can exceed power about 50% and run, thus can cancel front-mounted heating device, saves equipment investment scale.5. the present invention is stable, deaerating effect good, low pressure oxygen-eliminating device≤10ppb, and (ministry standard is 15ppb) higher-pressure deaerator≤3ppb(ministry standard is 7ppb).
