The utility model is related to boiler technology field, especially relates to a kind of flue gas processing equipment of boiler.
Background technology
Boiler, as a kind of energy conversion, has the forms such as chemical energy, electric energy in boiler input energy, and passes through pot The conversion of stove, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy, is wherein used for the boiler of coal combustion relatively For universal, but coal-burning boiler can produce substantial amounts of flue gas in use, contains nitrogen oxides, suspended particulate in this flue gas The multiple pollutants such as thing, sulfur dioxide, direct discharge can cause serious pollution to atmospheric environment, additionally, boiler exhaust gas heat waste Mistake is that most important one in boiler heat loss, exhaust gas temperature is higher, and heat loss is more, and exhaust gas temperature does not have reduction by 15~20 DEG C, then corresponding heat-energy losses reduce 1%.
Content of the invention
The purpose of this utility model is to provide a kind of flue gas processing equipment of boiler, to the high-temperature flue gas producing after fuel combustion Waste heat recycled and discharged again after the harmful substance in flue gas is processed, reduce heat-energy losses while protect Environment.
The technical solution of the utility model is: a kind of flue gas processing equipment of boiler, including boiler body, described boiler body Internal surrounding is provided with ring-shaped water jacket, described boiler body offers charging aperture, described boiler body top offers row Mouth, has combustion chamber in described boiler body, and described combustion chamber bottom offers air outlet, and described exhaust opening is connected with cigarette Gas processing system, described smoke processing system includes heat-exchanging water tank, cyclone separator, sack cleaner and absorption chamber, described changes It is provided with the exhaust gases passes in u shape structure, the delivery port of described heat-exchanging water tank passes through aqueduct and ring-shaped water jacket in boiler It is connected, described exhaust opening is connected with the air inlet of exhaust gases passes by gas pipeline, and the gas outlet of exhaust gases passes and whirlwind divide Connect from device, the gas outlet of cyclone separator is connected with the air inlet of sack cleaner, and suction is led in the gas outlet of sack cleaner Receive room, the top of described absorption chamber is provided with spray thrower, and the bottom of described absorption chamber is provided with waste collection pond, described absorption chamber On be provided with gas discharge outlet.
Further, described spray thrower includes several spray heads.
The utility model has the advantages and positive effects that:
1st, the exhaust opening on boiler body passes through entering of the exhaust gases passes in u shape structure in gas pipeline and heat-exchanging water tank Gas port connects, and substantially prolongs the time of staying in exhaust gases passes for the high-temperature flue gas, thus effectively transferring heat to heat exchange Water in water tank, the delivery port of heat-exchanging water tank is connected with ring-shaped water jacket by aqueduct, so that having uniform temperature Water circulation enters ring-shaped water jacket and is heated, is effectively utilized the heat energy of high-temperature flue gas, has saved the energy;
2nd, the flue gas after heat-exchanging water tank cooling sequentially passes through cyclone separator by the most of dust in flue gas and particle Remove, subsequently enter sack cleaner, further the micronic dust in flue gas is removed, finally enter absorption chamber, by shower water or Other absorbing liquids of person absorb to the pernicious gas in flue gas, and the waste liquid entrance waste collection pond absorbing gained is easy to subsequently locate Reason, finally by the fume emission after processing, greatly reduces the pollution to environment.
