Description
Technical field
The utility model is related to machinery field more particularly to a kind of oil-burning gas-fired boiler condensate drains.
Background technology
The convection part of double drum horizontal burning oil fuel gas boilers determines the pole in boiler operatiopn due to the characteristic of fuel itself
It is also easy to produce condensed water, especially when boiler at low load is run, condensation water quantity can sharply increase.Because of double drum Horizontal fuel combustions
Gas boiler convection section both sides are full film type wall sealing structure, cause generated a large amount of condensed waters to be gathered in convection section bottom, such as
Fruit stoker personnel cannot be discharged in time, and it will cause wall erosions on the outside of convection tube root and drum, for a long time, will influence pot
It the normal operation of stove and reduces the service life.
Utility model content
The purpose of utility model：In order to provide a kind of better oil-burning gas-fired boiler condensate drain of effect, specifically
Purpose is shown in multiple substantial technological effects of specific implementation part.
In order to reach purpose as above, the utility model adopts the following technical scheme that：
A kind of oil-burning gas-fired boiler condensate drain, which is characterized in that including straight tube, U-shaped bend pipe, square tube, blowdown
Valve, blind flange and ball valve；The upper end of square tube is mounted on membrane wall bottom, and lower end is connected to straight tube, and the front end of straight tube is equipped with U-shaped curved
Pipe, U-shaped bend pipe front are provided with ball valve, and ball valve is in normally open.
The further technical solution of the utility model is that the part of the both sides of the U-shaped bend pipe and straight tube docking includes
Strainer.
Using the utility model of technical solution as above, have the advantages that compared with the existing technology：1. can be continuous
A large amount of condensed waters that boiler convection section is accumulated are discharged in time, avoid condensed water to boiler convection pipe and drum lateral wall
Corrosion, to improve the service life of boiler so that boiler life improves 3 ~ 5 years.
2. front setting is U-shaped curved, water is played, the effect of water seal avoids flue gas and passes through condensate drain
It leaks.
Description of the drawings
In order to further illustrate the utility model, it is further illustrated below in conjunction with the accompanying drawings：
Fig. 1 is the front view of the utility model；
Fig. 2 is the side view of the utility model；
Fig. 3 is the structural schematic diagram of U-shaped bend pipe；
Wherein：1 ball valve；2U type bend pipes；3 blowdown valves；4 square tubes；5 straight tubes；6 blind flanges；7 membrane walls；8. strainer.
This attached drawing is the schematic diagram of present apparatus critical piece composition, does not represent the appearance and size, connection side of the utility model
Formula, assembling form, position relationship etc., it is illustrated that partially manual valve, pipe fitting etc. is omitted.
Specific implementation mode
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.It should be noted that making in being described below
Word "front", "rear", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" respectively refer to
Be directed towards or far from geometric center of specific component direction.
This patent provides a variety of concomitant regimens, in place of different expression, belong to modified scheme based on basic scheme or
It is parallel type scheme.Each scheme has the unique features of oneself.
A kind of oil-burning gas-fired boiler condensate drain, which is characterized in that including straight tube 5, U-shaped bend pipe 2, square tube 4, row
Dirty valve 3, blind flange 6 and ball valve 1；The upper end of square tube 4 is mounted on membrane wall bottom, and lower end is connected to straight tube 5, the front end of straight tube 5
Equipped with U-shaped bend pipe 2,2 front of U-shaped bend pipe is provided with ball valve 1, and ball valve 1 is in normally open.What the technical solution at this place was played
The technique effect and its realization process of essence are as follows：Illustrate present embodiment, present embodiment institute in conjunction with Fig. 1, Fig. 2 and Fig. 3
It states more square tubes 4 and is located at 7 bottom of boiler convection membrane wall, 4 lower part of square tube is connected to by straight tube 5,5 rear end of straight tube blind flange 6
Sealing, front end connection U-shaped curved 2, U-shaped curved 2 other end connect ball valve 1, and U-shaped curved 2 bottom is equipped with blowdown valve 3.Ball valve 1 is in normal
Open state.The purpose of such setting is that the cross-sectional area of square tube is larger, can effectively drain condensed water and other impurities, straight tube
Front end it is U-shaped it is curved can store a small amount of condensed water, when ensureing to generate condensation water quantity very little, convection tube root is also without product
Water.Meanwhile it is U-shaped it is curved in the water deposited can also play the role of sealing and prevent flue gas from leaking.Straight tube rear end is sealed with blind flange,
When straight tube blocks, removable blind flange utilizes the dredging pipelines such as iron wire.
When the utility model at work, condensed water can be drawn out to along more square tubes in straight tube, be flowed forwardly into along straight tube U-shaped
It is curved, it curved is discharged in blow-off line along ball valve by U-shaped.During discharging condensed water, the residue of furnace body can stay in straight tube
Lower part and U-shaped stoop portion.At this moment, the blind flange that can open straight tube rear end utilizes the dredgings such as iron wire；Open the U-shaped portion of stooping row
Dirty valve, sundries is excluded, and blow-off pipe, which is filled up blocking, to prevent sundries causes condensed water that can not discharge.
The beneficial effects of the utility model：
1. continuously a large amount of condensed waters that boiler convection section is accumulated can be discharged in time, condensed water is avoided to boiler
Wall erosion on the outside of convection tube and drum, to improve the service life of boiler so that boiler life improves 3 ~ 5 years.
2. front setting is U-shaped curved, water is played, the effect of water seal avoids flue gas and passes through condensate drain
It leaks.
The both sides of the U-shaped bend pipe 2 and the part of straight tube docking include strainer.As a further improvement, strainer energy
Impurity screening so that the case where being not in impurities accumulation in whole U-shaped bend pipe.
In a creative way, above each effect is individually present, moreover it is possible to the combination of the above results is completed with a nested structure.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
It restricts, but it can also be combined with each other in the absence of conflict, reach multiple effects and realize jointly.
Basic principles, main features, and advantages of the present invention has been shown and described above.Ability
The technical staff in domain should be recognized that the present utility model is not limited to the above embodiments, described in the above embodiment and specification
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model can also
There are various changes and modifications, these changes and improvements are both fallen in claimed range.
