The residual-heat utilization device can generate heated steam, hot air and hot water; the heating surface adopts a novel energy-saving form, thus being capable of greatly reducing the cost of the boiler, and having natural circulation of the horizontal evaporation heating surface. The residual-heat utilization device adopts a natural circulation mode to solve the water circulation of the horizontal evaporation heating surface, without adopting a hot water circulating pump, thus simplifying the system, saving a great amount of running cost and also greatly lowering the cost of the boiler.
Description
(1) technical field
The utility model relates to the boiler technology field, is specifically related to a kind of residual heat using device.
(2) background technology
If the waste heat boiler of present vertical layout adopts horizontal evaporating heating surface, water circulation way is a forced circulation, must adopt hot water circulating pump, if adopt the snakelike tube bank of structure of Natural Circulation heating surface by standard the positive pitch of spending greater than 15 should be arranged, this layout evaporating heating surface occupies the too big space of boiler.Significantly increased the height of boiler, the cost of boiler also significantly increases thereupon.
(3) summary of the invention
The purpose of this utility model is to provide a kind of employing novel energy-conserving pattern of heating surface, can significantly reduce the cost of boiler, the energy-efficient residual heat using device of horizontal evaporating heating surface Natural Circulation.
The purpose of this utility model is achieved in that it is vertical layout, comprise drum 1, cooling chamber 2, superheater 3, horizontal evaporating heating surface 4, air preheater 5 and economizer 6, drum 1 is arranged on the boiler upper end, cooling chamber 2 connects the waste heat boiler exhaust gas entrance 7 that is arranged on upper boiler, cooling chamber 2 lower ends are provided with superheater 3, superheater 3 lower ends are provided with horizontal evaporating heating surface 4, air preheater 5 is arranged on horizontal evaporating heating surface 4 belows, economizer 6 is arranged on air preheater 5 belows, and economizer 6 connects the waste heat boiler waste gas outlet 8 that is arranged on the boiler bottom.
The utility model also has some technical characterictics like this:
1, described horizontal evaporating heating surface 4 is the evaporation tube that circuitous level is arranged.
The utility model can produce vapours, hot-air, hot water.The employing novel energy-conserving pattern of its heating surface can significantly reduce the cost of boiler, horizontal evaporating heating surface Natural Circulation.The utility model adopts the mode of Natural Circulation to solve the water circulation of horizontal evaporating heating surface, does not adopt hot water circulating pump, has simplified system, and has saved a large amount of operating costs, has also reduced the cost of this type of boiler greatly.
Because the inlet flue gas poor quality of waste heat boiler, the cigarette temperature is generally on the low side, and technological requirement is tight, contains a large amount of pernicious gases in a lot of waste gas, as CO, SO
2Deng, requiring the boiler air leak rate of air curtain is zero, so boiler need adopt a large amount of water-cooled bag wall constructions, vertical layout is arranged in the water-cooled bag within the walls with all heating surfaces of boiler, existing boiler technology and national standard evaporating heating surface have the tube bank of upwards flowing of certain angle, significantly increased the height of boiler, if adopt the height of horizontal evaporating heating surface boiler to reduce greatly, the cost of boiler is significantly reduced.
The utility model can also industrial waste gas be a thermal source, according to concrete exhaust gas properties the unit that respectively is heated is reconfigured; The utility model can be as required, changes the different proportion relations that are subjected to hot cell, produce between pressure 2.8MPa～5.4MPa, between 300～450 ℃ of temperature, the steam of flow 20～100t/h and hot-air, the hot water of certain flow.
(4) description of drawings
Fig. 1 is the vertical waste heat boiler profile of the utility model;
Fig. 2 is the heating surface schematic diagram of conventional boiler.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
In conjunction with Fig. 1, it is vertical layout, comprise drum 1, cooling chamber 2, superheater 3, horizontal evaporating heating surface 4, air preheater 5 and economizer 6, drum 1 is arranged on the boiler upper end, cooling chamber 2 connects the waste heat boiler exhaust gas entrance 7 that is arranged on upper boiler, cooling chamber 2 lower ends are provided with superheater 3, superheater 3 lower ends are provided with horizontal evaporating heating surface 4, air preheater 5 is arranged on horizontal evaporating heating surface 4 belows, economizer 6 is arranged on air preheater 5 belows, and economizer 6 connects the waste heat boiler waste gas outlet 8 that is arranged on the boiler bottom.
In conjunction with Fig. 1-2, the comparison of two kinds of evaporating heating surfaces, if utilize conventional heating surface to be equal in the situation of heating surface area and same heating surface arrangement length in acquisition, the height of three groups of heating surfaces of the horizontal heating surface of aspect ratio that one group of heating surface of conventional heating surface is shared is also high. The beneficial effects of the utility model have:
1, Boiler Main Parameter:
Boiler rating 20～100t/h
Boiler nominal steam pressure 3～10Mpa (gauge pressure)
280～450 ℃ of boiler nominal steam temperatures
104 ℃ of boiler feed temperatures
400～1000 ℃ of waste heat exhaust gas entrance temperature
2, the utility model boiler produces by the waste gas that utilizes industrial production and follow and carries hot heating water and make it change steam into for need of production.
3, after feedwater enters boiler, flow through successively: economizer surface → drum → horizontal evaporating heating surface → superheater surface, be heated to 300～450 ℃, draw boiler for producing needs.
What the utility model can make boiler is subjected to hot cell compact more, and it is more reasonable to arrange, can fully effectively utilize the waste heat in the waste gas, breaks the traditional arrangement mode of waste heat boiler in the past, really reaches the effect of energy-saving and emission-reduction.The utility model boiler is a compact conformation, takes up an area of the little waste heat recovery apparatus in space, utilizes traditional material, adopts particular design, reduces the cost of boiler.
