Description
Technical field
The utility model relates to a kind of industrial smoke retrieving arrangement, relates in particular to a kind of drainage type zinc pot smog and reclaims cleaning apparatus, is mainly used in the zinc oxide fume that hot dip process is produced and reclaims and purifying treatment.
Background technology
Mostly the zinc pot smog retrieving arrangement of present domestic use is to adopt German, Italian, Japanese production technology.Its principle of work all is a dry process.Adopt the cloth bag filtering recovering device.The flue gas that the zinc pot is produced is transported to filtration unit by the aspiration channel of two sides, flue gas is discharged with the draft of wind-force by the cloth bag micropore.Installed power is big, the energy consumption height.Cloth bag will regularly replace.Equipment running cost height, main is that recovery of zinc cigarette and dust removing effects are undesirable.
Chinese patent publication number: CN201180152, open day: on 01 14th, 2009, utility model title " galvanizing pot smog retrieving arrangement ", proposed to be provided with dust gathering arrester at the edge of hot-galvanized cauldron, dust gathering arrester is communicated with the spray treater through tracheae, air outlet on the spray treater is communicated with gas shaft through induced draft fan, the nozzle of spray on the treater is communicated with service pump on being arranged on settling tank through pipeline, the technical scheme that the water port of spray treater bottom is communicated with settling tank through pipeline, simultaneously can also on the zinc pot edge on dust gathering arrester opposite, air lance be set, zinc-plated smog is blowed to dust gathering arrester.Greatly improved field staff's operating environment, reduced the pollution of flue gas to environment, reclaiming and a new height has been brought up in purification, economic benefit and society, environmental benefit are remarkable.But in use still there are some problems in the aforementioned techniques scheme, the one, the air inlet port of dust gathering arrester is less, zinc-plated smog enters induced draft fan again through the spray treater earlier, be provided with the retaining zine plate at air inlet position, the flue dust resistance to flow is bigger, air inducing resistance height, can't collect the bigger zinc fume of granularity in the zinc-plated smog, dust-collecting efficiency has much room for improvement, the 2nd, the length at the length of dust gathering arrester and air lance and zinc pot edge and highly suitable, be difficult to collect the zinc-plated smog that flies away zinc pot outside, also the zinc-plated smog in the zinc pot can be blowed to top and outside periphery sometimes, site environment is still had certain pollution.
Summary of the invention
The purpose of this utility model is that to overcome existing zinc pot smog retrieving arrangement dust collection effect not ideal enough, environment is still had the defective and the deficiency of certain pollution, a kind of dust-collecting efficiency height is provided, and zinc-plated smog reclaims fully, and the little drainage type zinc pot smog of environmental pollution reclaims cleaning apparatus.
For achieving the above object, technical solution of the present utility model is: drainage type zinc pot smog reclaims cleaning apparatus, an edge at hot-galvanized cauldron is provided with dust gathering arrester, dust gathering arrester is connected with the spray treater, air outlet on the spray treater is connected with gas shaft, the water port of spray treater bottom is communicated with settling tank through pipeline, the shower nozzle of spray on the treater is connected with water pump in being arranged on settling tank through pipeline, and another edge of the hot-galvanized cauldron relative with dust gathering arrester is provided with the drainage injector, described dust gathering arrester is conical tube or tetragon Taper Pipe, the opening of the big end of dust gathering arrester is towards hot-galvanized cauldron, the opening of small end is communicated with the mouth that advances of sediment box, the opening of small end is the circle or the tetragon mouth of pipe, the smoke outlet of sediment box is connected with the spray treater through induced draft fan and airduct, and the width that the width of the big end opening of described dust gathering arrester and drainage injector upper spray nozzle are arranged is all greater than the length at an edge of hot-galvanized cauldron.
Described dust gathering arrester is arranged on the edge of a broadside of hot-galvanized cauldron, the drainage injector is arranged on the edge of another broadside of hot-galvanized cauldron, on the dust gathering arrester width of big end opening be the hot-galvanized cauldron width 1.2-2.5 doubly, the width of drainage jet apparatus is than the big 400-1000 millimeter of width of hot-galvanized cauldron.
Described drainage injector is by gas blower, be connected the tracheae on the gas blower and be distributed on the tracheae and spout is formed towards one group of nozzle of hot-galvanized cauldron, described nozzle is higher than zinc pot platform 300-600 millimeter, on the described dust gathering arrester height of the distance of shaft centers zinc pot platform of little end opening be nozzle height 3-6 doubly.
Described sediment box is a straight tube shape, is provided with into mouth on the top of sediment box one end, is provided with smoke outlet in the bottom of the sediment box the other end, and advances mouth and smoke outlet is respectively arranged with ash damper in the inside of sediment box correspondence.
Compared with prior art, the beneficial effects of the utility model are:
1. dust gathering arrester is conical tube or tetragon Taper Pipe, and dust gathering arrester leads to induced draft fan through sediment box, zinc fog dust dirt enters dust gathering arrester under the pushing away of drainage injector and induced draft fan, drawing power, zinc fog dust dirt enters induced draft fan through dust gathering arrester and sediment box, zinc fog dust dirt mobile resistance in dust gathering arrester and sediment box is little, air inducing efficient is higher, particularly little spelter in the zinc fog dust dirt and zinc method particle are stopped by ash damper in sediment box, reduced erosion and the destruction of zinc fume effectively to the induced draft fan blade, improve the Working environment of induced draft fan, improved the work-ing life of induced draft fan.
Since the width that the width of the big end opening of dust gathering arrester and drainage injector upper spray nozzle are arranged all greater than the length at an edge of hot-galvanized cauldron, can collect more zinc fog dust dirt, help improving the Working environment of zinc pot platform, dust gathering arrester and nozzle are apart from the setting of zinc pot podium level, help the whole inflow of zinc fog dust dirt dust gathering arrester, and can not dispelled.The production scene does not have flue dust substantially, has greatly improved field staff's operating environment, has ensured the healthy of people, for good condition has been created in safety in production.
3. flow into the settling tank precipitation in the lump through water spray and the zinc fume particle that filters out in the spray treater, can reclaim.Because the flue dust rate of recovery height of work-yard, to airborne release be air through having purified, so greatly reduce of the pollution of zinc fog dust dirt to air.Water in the settling tank recycles again, can realize zero release, thereby protect environment.
When dust gathering arrester and drainage injector when two broadside correspondences of hot-galvanized cauldron are provided with, any equipment on the long limit of zinc pot platform can keep existing operating space, galvanized operation as beat zinc gray, the lifting plating piece is very convenient, has alleviated labour intensity.
Since control of dust configuration rationally, air inducing efficient improves, and makes the power reduction of induced draft fan and gas blower in the utility model, its installed power only is 1/4th of an import equipment, equipment running cost is low, maintenance cost is economized, improve work-ing life.And simple in structure, cost of manufacture is low, convenient operating maintenance, and to the recovery and the good purification of zinc oxide fume, economic benefit and society, environmental benefit is remarkable.
