Abstract
The invention relates to a high-temperature gas diffusing cage device. The high-temperature gas diffusing cage device is characterized in that the device comprises a valve seat (5) and a cage body (1), and the valve seat (5) is fixedly mounted at an outlet of a waste heat boiler center pipe (6); the bottom of the cage body (1) is fixedly mounted on the valve seat (5); a flange (2) is fixedly mounted at the top of the cage body (1); a flange cover (3) is mounted on the flange (2); a through hole is formed in the middle of the flange cover (3); a shaft sleeve (4) is fixedly mounted in the through hole. The high-temperature gas diffusing cage device has the advantages that high-temperature technological gas can be diffused evenly, the diffused gas flows round and round in a boiler, sufficient heat exchange is conducted between the gas in the boiler and a pipe bundle, and thus heat exchange efficiency is improved; the outlet temperature of the high-temperature technological gas can be accurately controlled, the number of action times of a regulating valve at the tail end of the center pipe is reduced, the service life of the valve is prolonged, and equipment cost is reduced.
Description
Technical field
The present invention relates to a kind of high-temperature gas and disperse cage assembly.
Background technique
Existing waste heat boiler is provided with the larger center tube of diameter in the middle of tube bank, can flow out for hot process gases and carry out cold and hot exchange with tube bank, because the temperature of process gas is often very high, in order to accurately ensure the outlet temperature of process gas, valve can be provided with at center tube outlet end to regulate, need the continuous action of valve and adjusting gas flow.Too concentrated from the hot process gases of center tube outflow, can not with all tube banks in boiler fully, uniform heat exchange, outlet temperature fluctuated being difficult to is controlled, at this moment the continuous action of valve is just needed to regulate, hot environment lower valve is easily out of shape, and long frequent movement can greatly reduce the working life of valve.
Summary of the invention
The object of this invention is to provide a kind of high-temperature gas and disperse cage assembly, the hot process gases of waste heat boiler can be dispersed after and tube bank realize abundant heat exchange.
A kind of high-temperature gas disperses cage assembly, its specialization is: comprise the valve seat being fixedly mounted on waste heat boiler center tube outlet port, and cage body, the bottom of this cage body is fixedly mounted on this valve seat, flange is installed with at the top of this cage body, this flange is provided with blind flange, in the middle of this blind flange, has through hole, this through hole is installed with axle sleeve.
Wherein be connected by fastening piece between blind flange with flange.
Wherein fixed installation refers to welding.
On the sidewall of cage body, be wherein provided with the through hole of some strips.
The invention has the advantages that and can realize evenly dispersing hot process gases, gas after dispersing does convolution flowing in boiler, and carry out abundant heat exchange with tube bank, improve heat exchange efficiency, and can accurately control hot process gases outlet temperature, reduce the modulating valve time of movement of center tube end, improve valve working life, reduce equipment cost.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the invention provides a kind of high-temperature gas and disperse cage assembly, comprise the valve seat 5 being fixedly mounted on waste heat boiler center tube 6 outlet port, and cage body 1, the bottom of this cage body 1 is fixedly mounted on valve seat 5, is installed with flange 2 at the top of this cage body 1, and this flange 2 is provided with blind flange 3, in the middle of this blind flange 3, have through hole, this through hole is installed with axle sleeve 4.
Wherein be connected by fastening piece between blind flange 3 with flange 2, such as stud bolt.Above-mentioned all fixed installations all refer to welding.Above-mentioned cage body 1 is the circular tube shaped of hollow, the sidewall of cage body 1 is provided with the through hole of some strips, such as uniform 12 elongated holes vertically arranged, concrete distribution mode also can be determined according to next corresponding to the tube bank position of its heat exchange, namely guarantees that through hole is near tube bank direction.
Embodiment 1:
Be illustrated in figure 1 hot process gases of the present invention and disperse cage, cage body 1 top of dispersing cage is adjusted to after proper site with flange 2 and is welded, blind flange 3 and axle sleeve 4 are welded and fixed, when modulating valve is installed in the future, valve rod can pass axle sleeve 4 endoporus, is connected by flange 2 finally by stud bolt with blind flange 3.During installation, after valve core head to be regulated and valve seat 5 sealing surface adjust and align, valve seat 5 and center tube 6 are welded and fixed, will the proper site of cage integral solder at valve seat 5 be being dispersed.
Existing waste heat boiler sets up larger-diameter center tube 6 in the middle of tube bank, disperse cage and be fixed on center tube 6 end, of the present inventionly disperse equidistant rectangular ring-like window cage cage body 1 having and can pass through for hot process gases, upper weld a slice flange 2, be connected and fixed by stud and blind flange 3, blind flange 3 design a through hole and welds with axle sleeve 4, can pass for regulating valve rod.The advantage of this structure is the hot process gases flowed out from center tube 6 evenly to be dispersed, and carries out abundant heat exchange with tube bank, improves heat exchange efficiency, and can accurately control hot process gases outlet temperature.
When cage cage body 1 and valve seat 5 are dispersed in welding, the position being processed with window should be made towards the direction of restraining, and all parts all adopt Cr25Ni20 heat-resistant material, through probationary certificate, evenly hot process gases can be dispersed by adopting said apparatus, gas after dispersing does convolution flowing in boiler, and carries out abundant heat exchange with tube bank, improves heat exchange efficiency.
