The efficient collecting dust-removing of lead-power machine rear class filter cylinder system
Technical field
The utility model relates to the efficient collecting dust-removing of a kind of lead-power machine rear class filter cylinder system.
Background technology
The generation of 2011 Taizhou of Zhejiang blood lead events has caused the comprehensive rectification of nationwide to lead-acid accumulator production enterprise, accelerates upgrading transition of industry.Cleaner production, environmental protection become the important theme that concerns lead-acid accumulator production enterprise final and decisive juncture.The discharge standard of lead fume, lead dust has improved in State Environmental Protection Administration, by original 0.7mg/m
3Be reduced to 0.2-0.25mg/m
3, new standard also is about to formal the promulgation and puts into effect.
Fig. 1 is conventional lead powder production system.Lead button is transported in the lead-power machine drum, by the lead-power machine drum do not stop rotation, lead button and drum, lead button and lead button are constantly rubbed, oxidative exfoliation formation lead powder (lead oxide) is not stopped on the lead button surface.The lead powder that forms again the mode by selection by winnowing through pulsed jet cloth filter collect be transported in the storage warehouse stand-by.And the tail gas of discharging can reach 0.7mg/m through the bag-type dust of secondary 36 bag dust collectors again
3The discharging standards qualified discharge.
Among Fig. 1: the 1st, the lead button storage warehouse; The 2nd, positive pressure fan; The 3rd, the lead-power machine main frame; The 4th, the cloth bag powder collector; The 5th, the secondary sack cleaner; 6 is negative-pressure air fan.Wherein positive pressure fan mainly plays powder spreading in the winnowing type lead-power machine, and the corresponding winnowing type lead-power machine that also has adopts the mode of mechanical powder spreading, and reason is identical.
The raising of discharge standard, conventional lead powder production system can not satisfy the requirement of production, and we have solved this problem with regard to needs for this.
Fig. 2 namely is the solution that generally adopts, and namely at the newly-increased three grades of spray treating columns of secondary collection powder dedusting rear class, it can guarantee that emission reaches 0.2-0.25mg/m
3Discharge standard.
Among Fig. 2: 1 is that lead button storage warehouse, 2 is that positive pressure fan, 3 is that lead-power machine, 4 is that cloth bag powder collector, 5 is that secondary sack cleaner, 6 is that negative-pressure air fan, 7 is that spray column, 8 is that feeding spraying pump, 9 is the secondary blower fan.But because gas is large by the pressure loss of spray treating column, must increase the pressure loss that negative-pressure air fan overcomes generation with the spray treating column, spray needs to use feeding spraying pump simultaneously, and this has just caused the waste of the energy to a great extent.Discharging after up to standard after the lead waste water that collect to produce through spray simultaneously still will be discharged the plumbic acid Sewage Disposal and processed, this has just increased the pressure of plumbic acid Sewage Disposal, can not reclaim well lead resource simultaneously.
Summary of the invention
The utility model provides the efficient collecting dust-removing of a kind of lead-power machine rear class filter cylinder system, especially at the high-efficiency dust removal system of the newly-increased three grades of filter cartridge dust removers of lead-power machine powder collector and two-stage dust removal equipment rear class.
The technical solution of the utility model:
The efficient collecting dust-removing of a kind of lead-power machine rear class filter cylinder system, comprise the lead button storage warehouse 1 that connects successively, positive pressure fan 2, lead-power machine 3, cloth bag powder collector 4, secondary sack cleaner 5 and negative-pressure air fan 6, the air outlet of described negative-pressure air fan 6 also is connected with filter cartridge dust remover 10.
Described cloth bag powder collector 4 is connected with secondary sack cleaner 5 with filter cartridge dust remover 10 stage casings.
The beneficial effects of the utility model are:
The efficient collecting dust-removing of the lead-power machine rear class filter cylinder system that the utility model provides is conducive to the raising of discharge standard, the utility model is not owing to needing to use spray to process, avoided to increase the drawback that negative-pressure air fan overcomes the pressure loss of generation with the spray treating column, avoided simultaneously spray to need to use the waste of the energy that feeding spraying pump causes.Reduce simultaneously the processing pressure of the plumbic acid Sewage Disposal of knowing clearly, can reclaim well lead resource.The utlity model has the advantage of environmental protection, efficient, energy savings, cleaner production.
Description of drawings
Fig. 1 is the structural representation of the lead powder production system of routine.
Fig. 2 namely is the solution that generally adopts, namely at the newly-increased three grades of structural representations that spray is processed of secondary collection powder dedusting rear class.
Fig. 3 is structural representation of the present utility model.
Among the figure: 1 is that lead button storage warehouse, 2 is that positive pressure fan, 3 is that lead-power machine, 4 is that cloth bag powder collector, 5 is that secondary sack cleaner, 6 is that negative-pressure air fan, 7 is that spray column, 8 is that feeding spraying pump, 9 is that secondary blower fan, 10 is filter cartridge dust remover.
The specific embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
Such as Fig. 3, the efficient collecting dust-removing of a kind of lead-power machine rear class filter cylinder system, comprise the lead button storage warehouse 1 that connects successively, positive pressure fan 2, lead-power machine 3, cloth bag powder collector 4, secondary sack cleaner 5 and negative-pressure air fan 6, the air outlet of negative-pressure air fan 6 also is connected with filter cartridge dust remover 10.
Cloth bag powder collector 4 is connected with secondary sack cleaner 5 with filter cartridge dust remover 10 stage casings.
The utility model such as Fig. 3 namely are the collection powder dedustings that filter cartridge dust remover 10 is applied to lead-power machine 3.It not only can guarantee that emission reaches 0.2-0.25mg/m
3Discharge standard, simultaneously filter cartridge dust remover belongs to the low pressure loss treatment facility, can not do any adjustment to original lead-power machine draught fan matching and can satisfy instructions for use.This has reduced the loss of the energy to a great extent, and the lead powder of simultaneously filter cartridge dust remover collection also can be good at reclaiming and uses, and has avoided occuring the possibility of secondary pollution.
Embodiment recited above is described preferred embodiment of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
