Abstract
The invention discloses a granular layer filtration device based dust cleaning system. The dust cleaning system is characterized by comprising the granular layer filtration device, a tubular heat exchanger, a bag filter and a draught fan; the granular layer filtration device is communicated with the tubular heat exchanger, the tubular heat exchanger is communicated with the bag filter, and the bag filter is communicated with the draught fan. Dusty gas is cooled through the tubular heat exchanger, the bag filter is adopted to remove dust, standard emission and recycling of the dusty gas are realized, and the dust cleaning system has the advantages of simpleness in structure and clean and environment friendly.
Description
Technical field
The present invention relates to a kind of soot cleaning system based on granular bed filter device, belong to dedusting technical field.
Background technology
Because the storage capacity of oil and natural gas is limited; the status of coal in world's energy-consuming is more and more important; the oxide that coal burning produces and dust emissions cause serious pollution to environment; therefore dust and oxide emissions is reduced; realize clean discharge, protection of the environment is extremely urgent.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, a kind of soot cleaning system based on granular bed filter device is provided, realizes the clean discharge of dusty gas.
The present invention adopts following technical scheme: a kind of soot cleaning system based on granular bed filter device, it is characterized in that, comprise granular bed filter device, pipe heat exchanger, sack cleaner, air-introduced machine, described granular bed filter device is connected with described pipe heat exchanger, described pipe heat exchanger is connected with described sack cleaner, and described sack cleaner is connected with described air-introduced machine.
Preferably, granular bed filter device upper one end passes into dusty gas, and the granular bed filter device top other end is discharged deashing dusty gas and is input to pipe heat exchanger, and clean gas is discharged in the lower end of granular bed filter device.
Preferably, one end of pipe heat exchanger passes into cold medium, and the other end of pipe heat exchanger discharges thermal medium.
Preferably, cold medium is cold air, and thermal medium is hot-air; Or cold medium is cold water, thermal medium is hot water.
Preferably, pipe heat exchanger is used for lowering the temperature.
Preferably, sack cleaner is used for carrying out dedusting.
Preferably, air-introduced machine is used for the evacuate air after by dedusting.
The beneficial effect that the present invention reaches: the present invention adopts pipe heat exchanger to lower the temperature to dusty gas, adopts sack cleaner to carry out dedusting, achieves qualified discharge and the recovery of dusty gas, has that structure is simple, the advantage of clean environment firendly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication marked in figure: 1-dusty gas, 2-clean gas, 3-granular bed filter device, 4-deashing dusty gas, 5-pipe heat exchanger, 6-cold air, 7-sack cleaner, 8-evacuate air, 9-air-introduced machine, 10-hot-air.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Fig. 1 is structural representation of the present invention, a kind of soot cleaning system based on granular bed filter device, it is characterized in that, comprise granular bed filter device 3, pipe heat exchanger 5, sack cleaner 7, air-introduced machine 9, granular bed filter device 3 is connected with pipe heat exchanger 5, pipe heat exchanger 5 is connected with sack cleaner 7, and sack cleaner 7 is connected with air-introduced machine 9; Pipe heat exchanger 5 is used for lowering the temperature, and sack cleaner 7 is used for carrying out dedusting, and air-introduced machine 9 is used for the evacuate air after by dedusting.
Granular bed filter device 3 upper one end passes into dusty gas 1, and the granular bed filter device 1 top other end is discharged deashing dusty gas 4 and is input to pipe heat exchanger 5, and clean gas 2 is discharged in the lower end of granular bed filter device 3; One end of pipe heat exchanger 5 passes into cold medium 6, and the other end of pipe heat exchanger 5 discharges thermal medium 10.
Preferably, cold medium 6 is cold air, and thermal medium 10 is hot-air; Or cold medium 6 is cold water, and thermal medium 10 is hot water.
Operation principle of the present invention: dusty gas 1 passes into after granular bed filter device 3 filters, clean gas 2 is flowed out from the lower end of granular bed filter device 3, input pipe heat exchanger 5 from the other end outflow deashing dusty gas 4 on granular bed filter device 3 top and carry out cooling temperature-fall period for passing into cold medium 6, heat outputting medium 10, and then pass into sack cleaner 7 and carry out dedusting, finally pass into air-introduced machine 9 and perform evacuate air 8.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
