Description
Technical field
The apparatus field of waste heat boiler is the utility model is related to, specially a kind of horizontal type waste heat boiler evaporator disperses
Pipe arrangement.
Background technology
As country applies also increasingly to the pay attention to day by day of energy-saving and emission-reduction, the Gas Turbine Generating Units of natural gas fuel
Extensively, therefore using gas turbine institute smoke discharging the application for the waste heat boiler for continuing UTILIZATION OF VESIDUAL HEAT IN is also more and more, waste heat boiler
The safe operation of part is also more and more concerned.Horizontal type waste heat boiler evaporator heating surface module typically uses integrated suspension knot
Structure, expand from up to down, and bottom expansion amount is larger；Evaporator down-comer also expands from up to down.General evaporator
Tube panel has several groups, is arranged along flue gas flow direction, because the wall temperature of several groups of evaporators is identical during normal operation, therefore evaporator next part
The swell increment of case is identical, and the arrangement of evaporator dispersion pipe is not required to consider expansion issues, need to only connect；But boiler startup
Initial stage, the medium temperature in each evaporator are different, and the medium temperature in the evaporator tube panel that flue gas first passes through is high, after by
Evaporator tube panel in medium temperature it is low, which results in the downward swell increment of each evaporator lower header is different, because of differential expansion
Larger swelling stress caused by meeting, so as to be damaged to evaporator heating surface module, influences the safe operation of boiler.
The content of the invention
In order to solve the above problems, the utility model provides a kind of horizontal type waste heat boiler evaporator dispersion pipe arrangement
Structure, it can absorb differential expansion, protect evaporator heating surface module not to be damaged, it is ensured that the safe operation of boiler.
Its technical scheme is such：A kind of horizontal type waste heat boiler evaporator dispersion pipe arrangement, waste heat boiler
Evaporator, evaporator lower header, evaporator down-comer, evaporator decline bottom of the tube allocation set case, evaporator dispersion pipe, institute
State afterheat boiler evaporator to be connected with the evaporator lower header, the evaporator down-comer declines bottom of the tube with the evaporator
Header connection is distributed, the evaporator lower header declines bottom of the tube allocation set case with the evaporator to be disperseed by evaporator
Pipe connects, it is characterised in that each evaporator declines is respectively arranged with the evaporation at left and right sides of bottom of the tube allocation set case
Device import dispersion pipe, described evaporator dispersion pipe one end connect the evaporator and decline bottom of the tube allocation set case sidepiece, institute
State the evaporator dispersion pipe other end and connect the evaporator lower header lower end, the evaporator dispersion pipe is flexible bending
Pipe.
It is further characterized by, and the evaporator dispersion pipe includes connecting the evaporator decline bottom of the tube distribution
The horizontal pipeline section of header, the vertical pipeline section of the connection evaporator lower header, the connection horizontal pipeline section and the vertical pipeline section
Arc pipeline section.
After structure using the present invention, due to being by with soft between evaporator lower header and decline bottom of the tube allocation set case
Property the connection of evaporator dispersion pipe, and with cambered, can be very good to absorb the differential expansion of evaporator lower header, protection
Evaporator heating surface module is not damaged, it is ensured that the safe operation of boiler.
Brief description of the drawings
Fig. 1 is that the utility model structure watches figure attentively；
Fig. 2 is the utility model structural side view.
Embodiment
See Fig. 1, shown in Fig. 2, a kind of horizontal type waste heat boiler evaporator dispersion pipe arrangement, afterheat boiler evaporator
1st, evaporator lower header 2, evaporator down-comer 3, evaporator decline bottom of the tube allocation set case 4, evaporator dispersion pipe 5, remaining
Heat boiler evaporator 1 is connected with evaporator lower header 2, and evaporator down-comer 3 declines bottom of the tube allocation set case 4 with evaporator and connected
Connect, evaporator lower header 3 declines bottom of the tube allocation set case 4 with evaporator and is connected by evaporator dispersion pipe 5, each evaporation
Device declines the left and right sides of bottom of the tube allocation set case 4 and is respectively arranged with evaporator dispersion pipe 5, evaporator dispersion pipe 5 one
End connection evaporator declines the sidepiece of bottom of the tube allocation set case 4, the other end of evaporator dispersion pipe 5 connection evaporator lower header 2
Lower end, evaporator dispersion pipe 5 are with flexible elbow.Evaporator dispersion pipe 5 includes connection evaporator down-comer bottom
Horizontal pipeline section 5-1 of the part with header 4, the vertical pipeline section 5-2 of connection evaporator lower header 2, the horizontal pipeline section 5-1 of connection with it is vertical
Pipeline section 5-2 arc pipeline section 5-3.
Claims (2)
