Description

Waste gas purification apparatus in stainless steel slag treatment process
Technical field
Purifier the utility model is related to the exhaust gas generated in Technology of Steel Slag Processing, specially stainless steel slag handle work Waste gas purification apparatus in skill.
Background technology
Slag processing is production link last in steel plant process flow.There is its distinctive processing work for stainless steel slag Skill:Slag ladle and carriage → slag bath → machinery is smashed to pieces →, which is boiled in a covered pot over a slow fire, which to be covered → fetching water → and boil in a covered pot over a slow fire material, → rises and covers that → cooling of fetching water → machinery stirring → is fetched water Cooling → entrucking outward transport.In each link of stainless steel slag treatment process, a large amount of exhaust gas is generated.Stainless steel slag handles work The exhaust gas properties generated in skill are very special:Exhaust gas is large-minded, tolerance fluctuation is violent, temperature is high, water vapour is more, dust content is high And stickiness weight, hall space is huge in addition, poor sealing etc., and therefore, the waste gas pollution control and treatment generated in stainless steel slag treatment process is Global problem.
Existing common cleaner, such as:Electric precipitation(It is dry, wet), cyclone dust removal, bag-type dust, Venturi scrubbing, spray The equipment such as tower, liquid column tower, foaming tower, tubulent contact tower, because equipment blocks, efficiency is low, resistance is big, power consumption is high, the small < of processing capacity 100Km3The problems such as/h and be not used to the exhaust-gas treatment in stainless steel slag treatment process, such as:Dust high viscosity, high solids, High humidity(Steam)So that the equipment such as electric precipitation, cyclone dust removal, foaming tower, tubulent contact tower, bag-type dust are because viscous glutinous(Wall)It blocks and nothing Method uses;Atm number and fluctuation so that the flue gas system resistance of Venturi scrubbing is big, is fitted to periodic job tolerance fluctuation Answering property is poor, and system investments are big, and operating cost is high;Huge exhaust-gas treatment amount so that common spray column, liquid column tower, foaming tower, The equipment such as tubulent contact tower can not meet the requirement of operating mode in processing capacity, even if equipment component therein can use, because of its sky The limitation of tower flow velocity, it is bulky, and inefficiency.
Invention content
The existing cleaner of the utility model solution easily blocks, processing capacity is small, resistance is big, thus can not be suitable for stainless The problem of waste gas purification in Technology of Steel Slag Processing, provide the waste gas purification apparatus in a kind of stainless steel slag treatment process.
The utility model adopts the following technical scheme that realization:Waste gas purification apparatus in stainless steel slag treatment process, It is connected in sequence by spray column, gas-liquid separator and demister, the fluid injector of spray column is two layers, and every layer of nozzle ring is around spray Leaching tower body is evenly distributed with, and two layers of nozzle can improve spray quality;Gas-liquid separator for be connected to spray column gas outlet and demister into It is between gas port, by bend pipe and the S-shaped pipeline that forms of straight tube concatenation, steam and grit mixture in gas, in gravity and warp It crosses under the action of the centrifugal force compound force field generated during bend pipe, they are agglomerated and abundant with duct wall during movement It contacts and condenses and generate gas-liquid separation, while grit mixture is attached to inner wall of the pipe particularly elbow internal wall, finally in pipeline Aggregation becomes larger and comes off in wall surface liquid film, and solution-air point of the gas in upper, liquid under is formed on the section of separator end From;Gas-liquid separation is carried out using S-shaped pipeline, not only gas treatment amount is big and device structure is simple, and separative efficiency is high;Demister packet The tank body with air inlet, gas outlet and the leakage fluid dram positioned at bottom is included, is provided with that top surface is closed, bottom surface is open, cone in tank body The pyramidal demisting inner core that face is formed by the baffle plate that circumferencial direction is uniformly arranged and fixed keeps gap between adjacent baffle, Demisting inner core wiper mechanism is additionally provided in tank body;Existing demister(It is commonly called as folded plate demister)Demisting core plate be usually tablet Formula or ridge type, and with fixed cleaning device(Simplest wiper mechanism is exactly the sparge pipe sprayed to demisting inner core), The demister feature of the utility model is to change the shape of demisting inner core, and pyramidal demisting inner core is not easy to plug, gas Treating capacity is big and occupies little space;Through the separated mixed gas of gas-liquid separator, when entering demister tank body, lower floor Leakage fluid dram discharge of the liquid directly through tank base, particle water droplet is contained on top(Mist)Gas, into demister cavity, gas In particle(Droplet)The Tortuous flow between baffle plate is constantly collided with baffle plate wall surface, and according to particle, inertia is big during exercise Small difference when the direction of motion changes, is captured, and therefore coacervating large particle drop, in gravity by baffling plate surface liquid film Under effect, removing is slid down along baffle plate, so as to fulfill the purpose of gas purification demisting;Qualified net gas through gas outlet outside Row;The particulate soil being retained on baffle plate, the flushing through demisting inner core wiper mechanism, sewage are still arranged by bottom leakage fluid dram Go out.
Waste gas purification apparatus in stainless steel slag treatment process described in the utility model(Also referred to as dynamic wave dedusting (device) Unit)It has the following advantages and effect:
(1) the present apparatus can be handled(It adapts to)High viscosity, high humility, high temperature, high dustiness exhaust gas, equipment do not block, and runs Normally, especially suitable for the waste gas purification in stainless steel slag treatment process;
(2) the present apparatus pressure loss is small, unit resistance≤1200Pa, compared with Venturi scrubber similar in washing effect, Only its 1/5~1/10, significantly reduce operating cost;
(3) present apparatus floor space is small, and compared with the similar tower equipment of washing principle, area is only their 20%;
(4) present apparatus processing capacity is big, separate unit(Set)Reach as high as 1000Km3/ h disclosure satisfy that different scales enterprise is most Dust removal requirement under number working condition;
(5) present apparatus single-stage unit efficiency of dust collection >=95%, higher than the efficiency of dust collection of similar cleaner;
(6) present apparatus simple in equipment, operation component be few, convenience easy to maintenance, the adaptability for tolerance fluctuation By force, it is durable, handy;Such as:Equipped with inspection platform, in a manner of pull, nozzle can be overhauled in the case that non-stop-machine;
(7) the present apparatus can also can use the mode for being similar to pendulum building blocks according to the condition of site space, and arbitrarily devised shape is special Not Shi Yongyu some extreme terrains or technological transformation project construction and upgrading, therefore, in addition to being suitable for stainless steel slag processing work Outside waste gas purification in skill, it can also be used to the waste gas purification of other identical operating modes.
