Abstract
The utility model discloses a highly-efficient and energy-saving calcium carbide waste heat power generation system, comprising a gas-fired boiler, a steam turbine and a generating set. A multistage steam generator is disposed between an inlet end of the gas-fired boiler and an air inlet pipeline, and an exhaust end of the gas-fired boiler is provided with a flue. A furnace chamber is provided with a heat exchange tube and a superheater. The air inlet pipeline is provided with a deduster, and a coal economizer and an air pre-heater are disposed in the flue. A steam pipe is connected to the multistage steam generator, the heat exchange tube, the superheater, and the coal economizer. The highly-efficient and energy-saving calcium carbide waste heat power generation system is advantageous in that the utilization rate of waste heat is high; energy waste can be prevented; obstruction of the gas-fired boiler can be prevented; flue gas contamination can be reduced.
Description
Technical field
The utility model relates to the cogeneration field, relates in particular to a kind of energy-efficient calcium carbide afterheat generating system.
Background technology
The flue gas coming from carbide furnace complicated component contains stickum and combustible component, adopts in the past common waste heat boiler to come recovery waste heat, and recovery difficult is large, and effect is very undesirable, and recovery utilization rate is always very low, causes a large amount of energy wastes; Owing to having stickum and a large amount of dust in flue gas, easily cause line clogging, and pollute comparatively serious.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of reasonable in design that the utility model provides, and recovery utilization rate is high, can avoid the energy-efficient calcium carbide afterheat generating system of line clogging.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of energy-efficient calcium carbide afterheat generating system, comprise gas fired-boiler, steam turbine and generating set, it is characterized in that: be provided with the multistage steam generator between gas fired-boiler inlet end and admission line, exhaust end is provided with flue, be provided with heat exchanger tube and superheater in furnace chamber, admission line is provided with deduster, is provided with economizer and air preheater in flue; Steam pipework is connected with above-mentioned multistage steam generator, heat exchanger tube, superheater, economizer.
The utlity model has following beneficial effect: the high-temperature flue gas that furnace of calcium carbide produces is after dedusting, at first carry out heat exchange with the multistage steam generator, and remove stickum, then enter in gas fired-boiler, combustible constituent burns, and last flue gas reclaims through economizer and air preheater.Its waste heat recovery utilization rate is high, avoids energy waste; Flue gas can avoid gas fired-boiler to stop up through dedusting, except the stickum processing, and reduces smoke pollution.
