Abstract
The utility model relates to a regular pollution discharging and capacity expanding device for boilers, which improves the existing capacity expanding device. The utility model adopts a horn-shaped center-downward water inlet device with a tongue and simultaneously adopts a butterfly valve -- floating ball type water discharging and sealing device. If steam needs to be recovered, the utility model is added with a secondary separator composed of a stainless steel screen net and a steam evening hole plate. The utility model has the advantages of reasonable integral structure design, obvious economic benefit and convenient and reliable operation and running; compared with the existing capacity expanding device of the same type, the volume of the utility model can be reduced about 70 percent and the metal consumption is greatly reduced so that he cost is greatly reduced.
Description
The utility model relates to the improvement to boiler periodical blowdown flash vessel.
Boiler periodical blowdown flash vessel (hereinafter to be referred as flash vessel) is as a kind of boiler accessory machinery, and its effect is the drain grain slag of furnace bottom, precipitation and corrosion product, is beneficial to the normal operation of boiler.The flash vessel of domestic production at present, use, its design feature is: adopt tangential gutter spill formula water inlet, do not have any carbonated drink separation equipment, the steam flow area is about half of cylindrical shell cross-sectional area, be not with ball float, directly draining keeps higher water level in the external liquid packing.This class flash vessel internal structure design is unreasonable, causes equipment volume huge, and it is many to consume steel, makes it with high costs.
In order to overcome these shortcomings that existing flash vessel exists, we have proposed a kind of boiler periodical blowdown flash vessel that has improved after decompression evaporation mechanism, carbonated drink stalling characteristic and method and water seal and automatic drain system are carried out theory study and experimental study.
The utility model adopts band tongue trumpet type central authorities water feed apparatus, and horn mouth is downward, and the height of Gravity Separation is 0.8～1.5 meter; Cancel external water seal, draining and water seal arrangement adopt butterfly valve float-ball type structure, are installed in the end socket and garden tube of flash vessel lower end, and it is made of butterfly valve, chain, ball float and porous guide pipe, when boiler blow-off, promptly can affect butterfly valve to open after the ball float emersion certain height, make the normal draining of flash vessel, when boiler stops blowdown, when water level descends in the flash vessel, ball float falls butterfly valve is shut thereupon, and flash vessel stops draining, keeps certain water level in device.The needs different according to the user if want recovered steam, are then installed by stainless steel cloth and are added the second separator that equal steam vent plate constitutes jointly.
The utility model adopts band tongue trumpet type central authorities water feed apparatus, has both helped vaporization, helps deslagging again, and the height of Gravity Separation is reasonable in design, not only helps to improve separating effect, and helps dwindling the overall dimensions of flash vessel again; Draining and water seal arrangement are safe and reliable to operation, and simple in structure accounting for occupies a narrow space; The second separator that is adopted is caught the efficient height of little water droplet, and the steam drop that causes is little, not cracky simple in structure, and mounting or dismounting are convenient.The utility model is compared with existing flash vessel of the same type, reasonable in internal structure, simple, though have identical effect, but equipment volume can be dwindled about 70%, metal wastage is significantly reduced, thereby price is reduced greatly, payback period shortens greatly, remarkable in economical benefits, operation operation simultaneously is convenient, reliable.
Accompanying drawing one is a boiler periodical blowdown flash vessel structure chart.
(1) steam (vapor) outlet is taken over; (2) end socket; (3) equal steam vent plate; (4) stainless steel cloth (when recovered steam, just adorning); (5) safety valve connecting pipe; (6) cylindrical shell; (7) supporting base; (8) water inlet is taken over; (9) level instrumentation nozzle; (10) band tongue horn mouth water inlet; (11) end socket; (12) ball float; (13) butterfly valve; (14) garden tube; (15) discharge outlet is taken over.
Embodiment
A boiler periodical blowdown flash vessel, diameter is φ 1300mm, highly is 1300mm, volume is 1.7m
3, and the diameter with existing flash vessel of the same type of same effect is φ 2000mm, highly is 3500mm, volume is 5.5m
3, volume of the present utility model is 30.9% of an existing flash vessel volume.
Claims (4)
1, a kind of boiler periodical blowdown flash vessel, has a cylindrical shell, having water inlet on the cylindrical shell takes over, cylindrical shell respectively has an end socket in two ends up and down, the upper end end socket is connected with steam (vapor) outlet and takes over, the lower end end socket is connected with draining and water seal arrangement, and this blowdown system is characterised in that taking over the water feed apparatus that is connected with water inlet adopts band tongue trumpet type central authorities water inlet structure, and horn mouth is downward.
2, flash vessel according to claim 1, the draining and the water seal arrangement that it is characterized in that being installed in flash vessel lower end end socket and the garden tube adopt the butterfly valve one float-ball type water-level control apparatus that is made of butterfly valve, chain, ball float and porous guide pipe.
3, flash vessel according to claim 1, the height that it is characterized in that Gravity Separation is a 0.8-1.5 rice.
4, flash vessel according to claim 1 is characterized in that if want recovered steam, adopts stainless steel cloth to add the common second separator that constitutes of equal spiracular plate, is installed in the top of cylindrical shell.
