Abstract
The invention relates to a boiler service life prolonging device. The device is arranged between the top of a boiler body and the lower part of an exhaust chimney, and comprises an inner cavity body, an outer cavity body and a water discharging opening; the inner cavity body is connected and communicated with a smoke outlet at the top of the boiler body; the lower part of the outer cavity body coats the lower part of the inner cavity body; the upper part of the outer cavity body is connected with the lower part of the exhaust chimney; a liquid accumulating cavity which can accommodate water is formed in the middle section parts of the outer cavity body and the inner cavity body; the upper part of the liquid accumulating cavity is communicated with an exhaust channel; the water discharging opening is formed in the bottom of the liquid accumulating cavity; the water discharging opening is communicated with the liquid accumulating cavity. According to the boiler service life prolonging device, condensed water in smoke is effectively led out of the boiler body; corrosion of a sulphide in water to a boiler is avoided; the service life of the boiler is prolonged.
Description
Technical field
The invention belongs to boiler plant field, be specifically related to a kind of boiler improving boiler life and increase longevity device.
Background technology
Fuel oil, combustion gas, coal-burning boiler generally produce condensed water when burning in flue, and its condensed water with the fume emission of burning to outside boiler body, but can not be back in boiler body along flue.Owing to containing sulfide in the mixture of flue gas and condensed water, so along with the backflow of condensed water, the sulfide with high acid-base value is back in boiler body together along with condensed water, easily causes boiler corrosion, greatly reduces the service life of boiler.
Summary of the invention
It is an object of the invention to provide a kind of boiler and increase longevity device.Condensed water in flue gas is derived outside boiler body by this device effectively, it is to avoid the condensed water medium sulphide content corrosion to boiler, improves the service life of boiler.
The technical solution used in the present invention:
Boiler increases longevity device, this device is arranged between boiler body top and smoke evacuation chimney bottom, this device includes inner chamber body, outer chamber and discharge outlet, inner chamber body is connected with the outlet flue at boiler body top and connects, the bottom of outer chamber and the bottom being coated on inner chamber body, and the top of outer chamber is connected with smoke evacuation chimney bottom, outer chamber and inner chamber body center section part fractal become a fluid collection chamber that can hold hydrops, fluid collection chamber top connects with discharge flue, and discharge outlet is arranged on bottom fluid collection chamber, and discharge outlet connects with fluid collection chamber.
Further, outer chamber stage casing outwardly convex forms a bulge shape structure, joint in described bulge shape structure Yu the epimere of outer chamber is provided with the drain changeover portion that smooth circular arc is formed, and the upper opening of inner chamber body is positioned at outer chamber inside and does not contact with outer chamber.
Further, described drain changeover portion is made up of the first arc section and the second arc section, the arc angle of the first arc section is less than 90 degree, and its center of arc is outside, the arc angle of the second arc section is less than 90 degree, and its center of arc is inside, the first arc section is connected with outer chamber epimere, and the second arc section and the first arc section connect.
Further, the external diameter of described inner chamber body is less than the internal diameter of outer chamber epimere.
Further, the top of described outer chamber is provided with the projection for clamping smoke evacuation chimney.
Compared with prior art it provides the benefit that the present invention: the present invention, when not changing boiler original structure, adds drainage system on boiler, it is to avoid the sulfur-bearing condensed water corrosion to boiler in flue gas, serves the effect of little structure your writing；Extradition water is drained into boiler exterior by discharge outlet by the present invention, makes maximize the service life of boiler；Present configuration is simple, and cost is low, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of outer chamber in Fig. 1.
Detailed description of the invention
As it is shown in figure 1, a kind of boiler increases longevity device, this device is arranged between boiler body top 1 and smoke evacuation chimney 2 bottom, this device includes inner chamber body 3, outer chamber 4 and discharge outlet 5, the middle part of inner chamber body 3 is discharge flue 6, and profile is a cylindrical body, and inner chamber body 3 and outer chamber 4 all adopt Stainless Steel to make；Outer chamber 4 stage casing outwardly convex forms a columned bulge shape structure 7, being provided with, with the joint of the epimere of outer chamber 4, the drain changeover portion 9 that smooth circular arc is formed in described bulge shape structure 7, the upper opening of inner chamber body 3 is positioned at outer chamber 4 inside and does not contact with outer chamber 4.
As shown in Figure 2, described drain changeover portion 9 is made up of the first arc section 10 and the second arc section 11, the arc angle of the first arc section 10 is 45 degree, and its center of arc is outside, the arc angle of the second arc section 11 is 45 degree, and its center of arc is inside, the first arc section 10 is connected with outer chamber 4 epimere, and the second arc section 11 is connected with the first arc section 10.
Such as Fig. 1, inner chamber body 3 is connected with the outlet flue at boiler body top 1 and connects, the bottom of outer chamber 4 and the bottom being coated on inner chamber body 3, the top of outer chamber 4 is connected with smoke evacuation chimney 2 bottom, the bulge shape structure 7 of outer chamber 4 and inner chamber body 3 center section part fractal become a fluid collection chamber 12 that can hold hydrops, fluid collection chamber 12 top connects with discharge flue 6, and discharge outlet 5 is arranged on bottom fluid collection chamber 12, and discharge outlet 5 connects with fluid collection chamber 12.The top of outer chamber 4 is provided with the projection 13 for clamping smoke evacuation chimney 2.
In the present embodiment, the external diameter of inner chamber body 3 is less than the internal diameter of outer chamber 4 epimere, and the hydrops so further ensured on outer chamber 4 tube wall does not fall out in boiler body.
During use during the boiler of the present invention, the flue gas that in boiler, burning is formed with condensed water along tube wall downstream to drain changeover portion 9 time, utilize the transition structure that drain changeover portion 9 is special, condensed water is drained in fluid collection chamber 12, flowing out from discharge outlet 5, so, condensed water will not flow back in boiler.
