The support frame is connected with the cyclone dust collector, the flue gas inlet pipe is connected to one side of the cyclone dust collector, the top of the cyclone dust collector is connected to one end of a dedusting outlet flue while the other end of the dedusting outlet flue is connected to one bottom side of a purification tower, an overflow pipe is connected to the bottom of a purification tower, an access hole is connected to one side of the purification tower, a horizontal flue is connected to the top end of the purification tower and a vertical flue, and a flue gas outlet pipe is connected to the bottom of the vertical flue. The boiler flue gas purification device has the advantages that dust and sulphur-containing substance in boiler flue gas are removed by a drying-wetting-drying method, the purification effect of flue gas is good, the desulfurization rate reaches more than 90%, use cost is low, convenience in installation is achieved, and pollution caused by the boiler flue gas to the environment is greatly reduced.
Description
Technical field
The invention provides a kind of flue purifier of boiler.
Background technology
The flue dust produced by fuel and other substance combustion processes, and to the flue dust that the mechanical processes such as solid material fragmentation, screening and conveying produce, dedusting is exactly these particles are separated from flue dust and the process being trapped, reclaim.
The technology of flue gas ash removal comprises sack cleaner technology, electric cleaner technology and electric bag combined dust catcher technology.
1. sack cleaner has features such as adapting to various Dust Characteristics flue gas, efficiency of dust collection is high, compact conformation floor space is little, flexible arrangement, filter bag easy accessibility, deashing are efficient thoroughly, stable equipment operation is reliable.
2. electric cleaner has dependable performance, efficiency of dust collection is high, high temperature resistance, reentrainment of dust are little, be easy to the features such as maintenance.
3. assembled electric bag dust collector is comprehensive utilization and the dedusting advantage organically combining electric cleaner and sack cleaner, first traps dust a large amount of in flue gas by electric field, then collects a kind of combination high-efficiency deduster of residue fine solid particle through cloth bag.There is the stable feature such as (≤50mg/Nm3), SR is little, service life of equipment is long, excellent performance of dedusting.
Deduster is of a great variety, whether adopts wetting agent by dust removal process, and deduster can be divided into dry collector and wet scrubber.Mechanical dust collector, wet scrubber (mainly Washing dust remover), filtration dust catcher, electric cleaner and sound wave dust separator can be divided into by the basic role principle in dust removal process.
Current dedusting method is based on dry dust removal, dust removing effects is difficult to the requirement reaching modern people, for the people more and more paying attention to environmental pollution, in air, PM2.5 content is a kind of hidden danger, and the technology being therefore badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of flue purifier of boiler.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of flue purifier of boiler, comprise bracing frame, flue gas inlet pipe, cyclone dust collectors and central authorities spray device, support frame as described above connects cyclone dust collectors, described cyclone dust collectors side connects flue gas inlet pipe, ash bucket is connected bottom described cyclone dust collectors, ash-valve is connected bottom described ash bucket, described cyclone dust collectors top connects dedusting exhaust pass one end, the described dedusting exhaust pass other end connects side bottom purifying column, overflow pipe is connected bottom described purifying column, described purifying column side connects manhole, described purifying column top connects horizontal flue, described horizontal flue vertical connecting flue, described vertical stack base connects flue gas and goes out pipe.
Be provided with central authorities in described dedusting exhaust pass and spray device.
Described purifying column inside is fixedly connected with support column, and described support post edges connects filter membrane, and be provided with swirl-flow devices around described filter membrane, described purifying column is provided with edge in the position that filter membrane is corresponding and sprays device.
Described vertical flue inside is provided with solid devulcanizer.
Described purifying column top inner wall connects dehydrator, is fixedly connected with overflow launder below described dehydrator at purifying column inwall.
The invention has the beneficial effects as follows: adopt dry-wet-dry mode to remove dust in boiler smoke and sulphur-containing substance, gas cleaning is effective, and desulfurization degree reaches more than 90%, and use cost is lower, and it is convenient to install, and greatly reduces the pollution of boiler smoke to environment.
