Abstract
The utility model discloses the defeated grey inner sleeve anti-drop device of one kind, including ash conveying pipe and inner sleeve, the inner sleeve is fixedly installed in ash conveying pipe inwall, inner sleeve one end connection air inlet, some orifice plates are provided with inner sleeve, orifice plate windward side, which is on inner sleeve, is provided with air outlet.By being improved to triangle disturbance mouth to inner sleeve V-type fish mouth, under the disturbance effect that original fish mouth is not influenceed, it is to avoid the grey gas of ash conveying pipe directly washing away to inner sleeve fish mouth root, prevent inner sleeve is thrust from coming off, it is ensured that inner sleeve using effect；Orifice plate is entirely disposed in inner sleeve, compared to air outlet centre position is arranged on, the bonding area between orifice plate and inner sleeve is increased, effectively prevents orifice plate from being blown off the pneumatic ash transmitting system failure caused, greatly extension pneumatic ash transmitting system service life.
Description
Technical field
The utility model is related to steam power plant field, and in particular to a kind of defeated grey inner sleeve anti-drop device.
Background technology
, easily there is regular plugging, electrostatic precipitator ash bucket in traditional single tube conveying technology, low, defeated grey ability of exerting oneself
Grey position is high and moves back electric field phenomenon, causes environmental pollution and influences the collection of dry ash, to tear pipe dredging, hand labor during processing plugging open
Intensity is big.The defeated gray technology of double-jacket tube can efficiently solve traditional single tube insurmountable " abrasion and plugging " is conflicting asks
Inscribe, in terms of improving defeated grey ability, reduction energy consumption, ensureing ash-transmission system safety and stability and economical operation, with unique advantage,
With the development of defeated gray technology, inner sleeve Manifold technology achieves good using effect in ash-transmission system, but is due to that inner sleeve is
It is placed in ash conveying pipe, long-term washes away and inner sleeve can be caused to come off, and causes inner sleeve ineffective, influences defeated ash, inner sleeve
Orifice plate in pipe is located at air outlet middle, and orifice plate very little, washes away with the bonding area in inner sleeve, easily cause hole for a long time
Plate comes off, and causes whole double-jacket tube ineffective.
Utility model content
The utility model aims to provide a kind of defeated grey inner sleeve anti-drop device, has solved current double-tube waste heat boiler
Inner sleeve present in technology is easy to fall off, orifice plate is easy to fall off causes the problem of pneumatic ash transmitting system fails.
The utility model is achieved by following technical solution：
A kind of defeated grey inner sleeve anti-drop device, including ash conveying pipe and inner sleeve, the inner sleeve is fixedly installed in defeated
Some orifice plates are provided with grey inner-walls of duct, inner sleeve one end connection air inlet, inner sleeve, orifice plate windward side, which is on inner sleeve, opens
There is air outlet.
The air outlet bore is equal to the aperture of orifice plate.
The inner sleeve is fixed in ash conveying pipe by steady pin.
The orifice plate external diameter is equal to inner sleeve bore, and orifice plate aperture is the half of orifice plate external diameter.
The orifice plate is fixedly welded in inner sleeve.
The beneficial effects of the utility model are：
Compared with prior art, a kind of defeated grey inner sleeve anti-drop device that the utility model is provided, by inner sleeve V
Type fish mouth is improved to triangle disturbance mouth, under the disturbance effect that original fish mouth is not influenceed, it is to avoid ash conveying pipe grey gas is to inner sleeve
Directly washing away for pipe fish mouth root, prevents inner sleeve is thrust from coming off, it is ensured that inner sleeve using effect；Orifice plate is entirely disposed in inner sleeve
In pipe, compared to air outlet centre position is arranged on, the bonding area between orifice plate and inner sleeve is increased, and effectively prevents that orifice plate from being blown
Fall the pneumatic ash transmitting system failure caused, greatly extension pneumatic ash transmitting system service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is inner sleeve structure chart of the present utility model；
In figure：1- ash conveying pipes, 2- inner sleeves, 4- orifice plates, 5- steady pins, 6- air outlets, 7- air inlets.
Embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing, but required protection domain is not
It is confined to described；
As shown in Fig. 1~2, a kind of defeated grey inner sleeve anti-drop device that the utility model is provided, including the He of ash conveying pipe 1
Inner sleeve 2, the inner sleeve 2 is fixedly installed in the inwall of ash conveying pipe 1, the one end of inner sleeve 2 connection air inlet 7, inner sleeve 2 and set
There are some orifice plates 4, the windward side of orifice plate 4, which is on inner sleeve 2, is provided with air outlet 6, wind enters in inner sleeve 2 from air inlet 7, in warp
When crossing air outlet 6, Partial shrinkage gas can be flowed into ash conveying pipe 1 from air outlet 6, and another part is from then passing through the hole of orifice plate 4
In interior inflow inner sleeve 2, next air outlet 6 is continued flow through.
The bore of air outlet 6 is equal to the aperture of orifice plate 4, makes the flow of holes consistent, reaches the effect of shunting.
The inner sleeve 2 is fixed in ash conveying pipe 1 by steady pin 5, and steady pin 5 is provided with several, it is ensured that inner sleeve 2
It will not be come off out of ash conveying pipe 1.
The external diameter of orifice plate 4 is equal to the internal diameter of inner sleeve 2, and the aperture of orifice plate 4 is the half of the external diameter of orifice plate 4.
It is somewhat complicated that the orifice plate 4 is fixedly welded on welding procedure in inner sleeve 2, but can ensure that orifice plate 4 will not including
Occur sliding phenomenon in sleeve pipe 2.
