Description
Technical field
The present invention relates to waste heat boiler field more particularly to a kind of fire-tube type waste heat boilers for being able to ascend utilization rate of waste heat
Furnace.
Background technique
Waste heat boiler is using the waste heat in industrial processes and to generate the boiler of steam, belongs to and a kind of utilizes high temperature substrate
Stream is used as heat source, and is both the cooler of industrial production high temperature logistics by exchanging heat with water to generate the heat exchanger of steam,
It is to provide the device of steam using waste heat, is circulated in heat exchanger tube according to high-temperature gas or circulated outside heat exchanger tube, waste heat boiler
Furnace is divided into fire tube waste heat boiler and waterpipe type waste heat boiler, and fire tube waste heat boiler is that high-temperature gas flows in heat exchanger tube,
Recirculated water flows into boiler bottom through down-comer from drum, and contacts and be heated with heat exchange tube wall in boiler, and it is mixed to be converted into carbonated drink
Object is closed, steam water interface rises in boiler and returns to drum by tedge, is equipped with water separator, steam-water mixing in drum
Object carries out steam-water separation in drum, and the saturated vapor isolated is flowed out from the gas outlet of drum, and the recirculated water isolated is again
Boiler, which is flowed into, through down-comer carries out circulating-heating evaporation.
Existing fire tube waste heat boiler, the high-temperature gas as heat source first flow into Process Gas import, then from Process Gas into
More heat exchanger tubes separately flowing into boiler of mouth exchange heat, after the gas after heat exchange is flowed out from more heat exchanger tubes, then concentrate from
Process Gas outlet stream goes out boiler;
But the air inlet that the structure of the Process Gas import of existing fire tube waste heat boiler will cause high-temperature gas is uneven, makes height
Wet body causes the temperature of each heat exchange tube wall different, makes recirculated water in boiler without uniformly flowing into each heat exchanger tube of normal direction
Uneven heating when contacting with each heat exchange tube wall, influences heat transfer effect and slows down the circulation rate of steam water interface, reduce fire
The utilization rate of waste heat of tubular type waste heat boiler;
Also, high-temperature gas, although exchanging heat in heat exchanger tube with recirculated water, drops gas temperature after flowing out in heat exchanger tube
It is low and a large amount of waste heats is allowed to be utilized, but the gas temperature after exchanging heat still has hundreds of degree, wherein the waste heat contained still quite may be used
It sees, the gas after above-mentioned heat exchange can be expelled directly out by existing fire tube waste heat boiler, and can not remain in the gas after heat exchanging
