Abstract

The invention discloses a deaerator. The deaerator is simple in structure, easy to manufacture, high in reliability, low in cost and better in deaeration effect. According to the technical scheme, annular plates are arranged on the lower portion of the deaerator; equilateral angle steel of which two edges are provided with through holes is arranged on the bottom faces of the annular plates; all the planes where the two edges of the equilateral angle steel are located form 45-degree angles with the corresponding planes where the annular plates are located; steel bars are arranged under the equilateral angle steel; connection between the deaerator and the annular plates, connection between the annular plates and the equilateral angle steel and connection between the equilateral angle steel and the steel bars are all achieved through welding.

Description

A kind of oxygen-eliminating device

Technical field

The present invention relates to a kind of deaerator device, particularly relate to a kind of spray type deaerator.

Background technology

Deaerator equipment is one of equipment indispensable in boiler feedwater heat regenerative system.Dissolved oxygen in feedwater can cause the serious corruption of boiler and relevant device, therefore needs dissolved oxygen to remove as much as possible.At present, due to the uncertain of boiler feedwater environment and the structural design of oxygen-eliminating device self, there is the present situation that deoxidize rate is low, make from oxygen-eliminating device water out also containing a certain amount of oxygen, thus serious threat is formed to the corruption of boiler and relevant device, also the safe operation of whole steam generator system is formed and hinder.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of oxygen-eliminating device.

The technical solution adopted in the present invention is: be provided with ring flat-plate in the bottom of oxygen-eliminating device, the bottom surface of ring flat-plate is provided with the equal leg angle of two sideband through holes, the plane at place, two limits of equal leg angle all becomes 45 ゜ angles with the plane at ring flat-plate place, and the below of equal leg angle is provided with steel bar.

The arrangement of ring flat-plate is point three layers of equidistantly placement, and every layer of ring flat-plate quantity arranged is identical, and spacing is 45mm ~ 50mm.The arrangement mode of equal leg angle is that equidistantly wherein spacing is 10mm ~ 15mm, and the equal leg angle of adjacent two ring flat-plate bottom surfaces staggers mutually; The arrangement of same layer equal leg angle is identical, and the arrangement of adjacent two layers equal leg angle is orthogonal.Two limits of equal leg angle are provided with equally spaced through hole.Steel bar is with the ring flat-plate center of circle for symmetric points symmetry is fixed on oxygen-eliminating device, and the direction of steel bar is vertical with equal leg angle.

Compared with prior art, the invention has the beneficial effects as follows that (1) the present invention is directed to prior art Problems existing, design and manufactured the better oxygen-eliminating device of deaerating effect, reduce number of devices; (2) structure is simple, is easy to manufacture, and only on the basis of original oxygen-eliminating device, slightly need increase, namely can be made into; (3) reliability is high, and cost is lower.

Detailed description of the invention

Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:

In Fig. 1, the internal diameter of oxygen-eliminating device is 1400mm, and the thickness of ring flat-plate is 8mm, and internal diameter is 1300mm, and external diameter is 1400mm, and ring flat-plate divides three layers to be arranged in oxygen-eliminating device lower area according to spacing 50mm, 3 every layer, and ring flat-plate and oxygen-eliminating device inwall are weldingly connected.No. 5 equal leg angles are according to spacing 10mm arrangement, and the equal leg angle on the downside of adjacent two ring flat-plates staggers mutually; The two ends of equal leg angle and the bottom surface of ring flat-plate are weldingly connected, and the plane at place, two of equal leg angle limits all becomes 45 ゜ angles with the plane at ring flat-plate place; Middle level equal leg angle is horizontally disposed, and upper and lower two-layer equal leg angle is arranged vertically.

In Fig. 2, the steel bar of diameter 8mm is fixed on oxygen-eliminating device with the ring flat-plate center of circle for symmetric points are symmetrically welded, and the arranged direction of steel bar is vertical with angle steel, and the distance in steel bar and the ring flat-plate center of circle is 300mm.

In Fig. 3, the through hole of diameter 6mm is sequentially arranged on two limits of No. 5 equal leg angles according to the spacing of 15mm.

Water sprays into oxygen-eliminating device inner space from the nozzle 7 on oxygen-eliminating device top, after contacting with the heating steam entering oxygen-eliminating device from delivery port 1, be heated to corresponding to the saturation temperature under oxygen-eliminating device operating pressure, realize one-level deoxygenation, the condensate water obtained after deoxygenation is still containing higher dissolved oxygen.Condensate water after one-level deoxygenation continues to fall, enter oxygen-eliminating device lower area, owing to equal leg angle 3 existing a large amount of through holes 7, condensate water is uniformly distributed in oxygen-eliminating device lower area and has larger specific area, meanwhile, the existence of equal leg angle 3, ring flat-plate 4 and steel bar 5 slow down the falling speed of condensate water, and the condensate water containing remaining dissolved oxygen is contacted fully completely with post bake steam, remaining dissolved oxygen is removed further, and water oxygen level reduces further.Water after secondary deoxygenation is discharged from delivery port 1.
