Description
Technical field
This utility model relates to a kind of waste heat boiler hot process gases and dissipates cage.
Background technology
Existing waste heat boiler is provided with, in the middle of tube bank, the central canal being relatively large in diameter, and is available for high-temperature technology gas
Body flow out and carry out cold and hot exchange, owing to the temperature of process gas is the highest, in order to accurately protect with tube bank
The outlet temperature of card process gas, can be provided with valve at the central canal port of export and be adjusted, need valve
Constantly action adjusting gas flow.The hot process gases gone out from center pipe flow is excessively concentrated,
Can not all tube banks heat exchange abundant, uniform with boiler so that outlet temperature is controlled by fluctuated being difficult to
System, is at this moment accomplished by the continuous action of valve and is adjusted, but hot environment lower valve is easily deformed,
Frequent movement can greatly reduce the service life of valve for a long time.
Utility model content
The purpose of this utility model is to provide a kind of waste heat boiler hot process gases and dissipates cage, it is possible to
The hot process gases of waste heat boiler is dissipated afterwards and tube bank realizes abundant heat exchange.
A kind of waste heat boiler hot process gases dissipates cage, and it is particular in that: include fixing peace
Being contained in the valve seat in waste heat boiler central canal exit, and cage body, the bottom of this cage body is fixedly mounted on
On this valve seat, it is installed with flange at the top of this cage body, this flange is provided with blind flange,
In the middle of this blind flange, have through hole, this through hole is installed with axle sleeve.
Wherein it is connected by securing member between blind flange with flange.
Wherein fixed installation refers to welding.
On the sidewall of cage body, wherein it is provided with the through hole of some strips.
The utility model has the advantage of and can realize uniformly dissipating hot process gases, the gas after dissipating
Body does swirling flow in boiler, and carries out abundant heat exchange with tube bank, improves heat exchange efficiency, and can be accurate
Really control hot process gases outlet temperature, reduce the regulation valve events number of times of central canal end, improve
Valve service life, reduce equipment cost.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model provides a kind of waste heat boiler hot process gases dissipates cage,
Including being fixedly mounted on the valve seat 5 in waste heat boiler central canal 6 exit, and cage body 1, this cage body 1
Bottom be fixedly mounted on valve seat 5, be installed with flange 2 at the top of this cage body 1, in this method
On blue 2, blind flange 3 is installed, in the middle of this blind flange 3, has through hole, fixing peace on this through hole
Equipped with axle sleeve 4.
Wherein it is connected by securing member between blind flange 3 with flange 2, such as stud.Above-mentioned institute
Fixed installation is had to refer both to welding.Above-mentioned cage body 1 is the circular tube shaped of hollow, on the sidewall of cage body 1
It is provided with the through hole of some strips, the most uniform 12 elongated holes being vertically arranged, concrete distribution mode
Can also should determine that mutually according to the tube bank position with its heat exchange, i.e. guarantee that through hole is near tube bank direction.
Embodiment 1:
It is illustrated in figure 1 hot process gases of the present utility model and dissipates cage, dissipate in the cage body 1 of cage
Portion is adjusted to after proper site with flange 2 weld, and blind flange 3 is welded and fixed with axle sleeve 4, will
When installing regulation valve, valve rod can pass axle sleeve 4 endoporus, finally by stud by flange 2
It is connected with blind flange 3.During installation, valve core head to be regulated and valve seat 5 sealing surface adjust after aligning,
Valve seat 5 is welded and fixed with central canal 6, the cage integral solder proper site at valve seat 5 will dissipated.
Existing waste heat boiler sets up larger-diameter central canal 6 in the middle of tube bank, dissipates cage and fixes
At central canal 6 end, of the present utility model dissipate have in cage cage body 1 be available for hot process gases lead to
The equidistant strip ring-like window crossed, a piece of flange of upper weld 2, by studs and blind flange 3
Connect fixing, blind flange 3 design a through hole and welds with axle sleeve 4, being available for regulating valve rod and wear
Cross.The advantage of this structure is uniformly to be sent out by the hot process gases flowed out from central canal 6
Dissipate, carry out abundant heat exchange with tube bank, improve heat exchange efficiency, and can accurately control hot process gases and go out
Mouth temperature.
When welding dissipates cage cage body 1 and valve seat 5, the position being machined with window should be made towards the side of tube bank
To, and all parts all use Cr25Ni20 heat proof material, test proves that, by using
Said apparatus can uniformly dissipate hot process gases, and the gas after dissipating does swirling flow in boiler
Dynamic, and carry out abundant heat exchange with tube bank, improve heat exchange efficiency.
