Description

Coating film on glass exhaust-gas treatment dry method energy saving technique
Technical field
New technology of the present invention is the novel process that a cover utilization dry method power-saving technology is handled online coating film on glass waste gas.
Background technology
The waste gas main component that online coating film on glass technology produces is organic fuel gas, flue dust, sulfur-containing smoke gas etc., and the improvement to this type pernicious gas is main with wet method in the world.Domestic waiting developed, and has certain difficulty and problem with high investment on the treatment technology.Multi-stage processing equipment is connected and technological design is very big difficult point, especially a wet processing process, and deacidification efficiency is low, brings the secondary pollution and the processing of water, increases a lot of difficulties and trouble.At present; The coating process that many sized glasses enterprise arranged in various degree exist exhaust emission discharging exceed standard (national standard); Country has issued plate glass technology waste gas discharge standard; But formulate as yet for coating film on glass technology waste gas discharge index relevant criterion, more at present glass industry waste gas standards wait perfect, and the coating film on glass waste gas pollution control and treatment is badly in need of more specialty, the more innovative technology appearance of standard, higher Governance Ability.
Can be used as the glass stove dedusting of the routine of reference, the technology that desulfurization is mainly adopted is wet dedusting, sulfur removal technology: mainly the advanced waste heat boiler of high-temperature flue gas (or cooler) is cooled off, when flue-gas temperature is lower than 250 ℃, flue gas is sent into high-efficient desulfation dust-extraction device and carry out desulfurization and dedusting and handle by air-introduced machine.Flue gas contacts with deacidification agent from the cleaning solution circulatory system in high-efficient desulfation dust-extraction device; Under the chemistry of a series of complicacies, physical action; Sulfur in smoke is washed liquid and absorbs, and the flue dust aggegation sedimentation in the flue gas simultaneously and be washed liquid and take away reaches the purpose of desulfurization and dedusting.Through flue gas after being purified, in high-efficient desulfation dust-extraction device, effectively dewater, the flue gas after the dehydration is effluxed by chimney stack.
The waste gas that coating film on glass produces is different from conventional glass stove flue gas, except that containing conventional glass stove smoke components, with the used film formulation composition of coating process much relations is arranged; Exhaust gas properties is main with organic exhaust gas; The higher suitable burning disposal of concentration also contains heavy metal particles, dust etc. simultaneously.So the present invention is combining to develop the dry method energy saving technique of innovative practical coating film on glass waste gas pollution control and treatment on the conventional glass stove flue gas managing technique basis.
Summary of the invention
The purpose of the present invention's technology is to satisfy the needs of coating film on glass waste gas pollution control and treatment, and the invention of glass plated film waste gas organic exhaust gas wet method sulphur removing and dust removing technology is dry method energy-saving desulfuration dust collecting process, provides a cover the complete efficient improvement technology that can be applicable to the practical applications scale.
For realizing above-mentioned purpose, the technology path that the present invention adopts is: a whole set of technology is made up of CIU, cooling system, dust pelletizing system, desulfurization dewatering system.Wherein CIU is made up of incinerator and built-in burner, and cooling system is made up of air blast cooling cooler and circulating water cooling system, and dust pelletizing system is made up of sack cleaner, and desulphurization system is made up of new type power ripple spray tower.Waste gas gets in the exhaust treatment system through air-introduced machine; Waste gas burns harmless treatment through incinerator to reluctant organic exhaust gas earlier; Get into air-cooled cooler through the waste gas after burning then and lower the temperature, waste gas gets into sack cleaner again and carries out dedusting, and waste gas gets into the dynamic wave spray tower more then and carries out desulfurization; Get into the waste gas of high-efficiency dust remover after at last and carry out dedusting, finally discharge through chimney by the 2# blower fan to desulfurization.
This invention technology mainly is made up of following apparatus and process: air-introduced machine (1), incinerator (2), wind cooling temperature lowering device (3), sack cleaner (4), turbulent flow spray tower (5), high-efficiency dust remover (6), dust compartment (7), backflow blower fan (8), exhaust blower (9), chimney (10).
Technology of the present invention has following advantage: 1. can use as the engineering large-scale promotion, realize commercialized running; 2. filled up the blank of coating film on glass waste gas dry treatment, perfect glass industry waste gas dry treatment technology; 3. dry treatment does not have problem of secondary pollution, and treatment cost is reduced, and governance process is energy-conserving and environment-protective more; 4. the dry treatment reaction is more abundant, and desulfuration efficiency improves; 5. technology is workable, has realized full-automatic operation, is that a cover is efficient, science, reasonable, lasting waste gas pollution control and treatment system, has favorable social and economic benefits.
Accompanying drawing and description of drawings
Fig. 1 is a coating film on glass emission control technology sketch map.
The specific embodiment
Below in conjunction with accompanying drawing patent of the present invention is done further explanation.
Plated film can produce a large amount of toxic and harmfuls and material, and these toxic and harmfuls get into incinerator through air-introduced machine.Through 800 ℃ high temperature incineration, noxious material burns the generation chemical reaction and makes inorganicization of organic exhaust gas organic exhaust gas under this high temperature, produce a large amount of sour gas and dust characteristic oxide in incinerator.
The flue gas of waste gas after incinerator burns makes flue-gas temperature be lower than the load temperature of deduster cloth bag by wild air cooling in the wind cooling temperature lowering device between 400-600 ℃.Wild wind is squeezed into the wind cooling temperature lowering device by axial flow blower around from the scene, in the wind cooling temperature lowering device with high temperature incineration after flue gas carry out heat exchange.
Flue gas in the cloth bag load temperature in deduster under rational filtration velocity through the cloth bag filtration, the dust in flue gas composition filtered be trapped in the dust collector ash hopper.
Dustless flue gas gets into the turbulent flow spray tower, and oversaturated deacidification agent gets in the tower body with solid-state attritive powder shape in the tower, and deacidification agent fully contacts with sour gas and absorbs sour gas simultaneously.
Flue gas after being purified also contains a spot of deacidification agent, carries out further dust removal process through high-efficiency dust remover again, and clean flue gas and a spot of deacidification agent are separated, and flue gas after being purified is discharged through chimney by exhaust blower.The deacidification agent of being separated by high-efficiency dust remover simultaneously gets into dust compartment, and the power that relies on the backflow blower fan to provide is back to remaining deacidification agent and fully contacts with sour gas once more in the turbulent flow spray tower and absorbs sour gas simultaneously.
