Description
Technical field
The invention belongs to the flue gas dry desulfurizing process flows of iron and steel domain, and in particular to be a kind of turbulent closure scheme formula sintering
Machine flue gas dry desulfurizing device.
Background technique
With environmental regulation increasingly strictly with the aggravation of environmental problem, in order to which the row of sulfide in flue gas is effectively reduced
It puts, contains the sprawling of acid rain, steam power plant uses different desulfurization and denitrification apparatus technique to handle to reduce flue gas one after another
Pollution to environment.Most common flue gas desulfurization technique mainly has wet type (lime/lime stone-gypsum), half dry type (spraying dry
Dry method), absorption and regeneration formula, spray one humidification activation formula of calcium etc..
So in the actual operation process, since desulfuration efficiency is low and reaction is incomplete, cause the utilization rate of desulfurizing agent not high,
Environmentally friendly increased costs, it is therefore necessary to study a kind of device to solve the above problems.
Summary of the invention
In order to change the low problem of current desulfuration efficiency, working principle of this patent based on Venturi tube can be mentioned further
High desulfurization efficiency, while the device is located at the front end of the rear end of sintering machine, bag filter or electrostatic precipitator, is sintering machine cigarette
The independent process of qi exhaustion sulphuring treatment.
Specifically, a kind of turbulent closure scheme formula sintering device flue gas dry desulfurization device, including gas inlet flue, desulfurizing agent master
Adding mouth, desulfurizing tower, uniformly distributed comb, exhanst gas outlet, warehouse, clean flue gas entrance, desulfurizing agent assist adding mouth, further include setting
Gas inlet trunnion and gas inlet before flue gas enters tower are flared, and the main adding mouth of desulfurizing agent is arranged in gas inlet trunnion
Place, the uniformly distributed comb are arranged inside desulfurizing tower, and before exhanst gas outlet.
Preferred embodiment, the desulfurization tower bottom are additionally provided with clean flue gas and enter the secondary auxiliary trunnion before tower and secondary auxiliary
Flaring, the desulfurizing agent auxiliary adding mouth are arranged at secondary auxiliary trunnion.
Preferred embodiment, the material selection high-carbon steel of the uniformly distributed comb.
The invention has the advantages that
1. venturi arrangement is arranged before flue gas is entered tower, and the main adding mouth of desulfurizing agent is arranged in the trunnion of Venturi tube
Place, using underbalance effect, is mixed into desulfurizing agent in high velocity smoke, and (flow velocity exists the turbulence effect generated again by import flaring
When change dramatically, fluid will generate violent turbulent flow), promote being sufficiently mixed for desulfurizing agent and flue gas.Such arrangement makes full use of
Flue space, not only reduces the space occupied of equipment, and substantially prolongs desulfurizing agent and mix with flue gas the reaction time, mentions
Desulfuration efficiency is risen；
2. uniformly distributed comb is arranged before exhanst gas outlet, it is intended that be evenly distributed with to the intracorporal flue gas of tower, prevent local velocity
The insufficient problem of reaction caused by too fast, while venturi principle is utilized again, turbulent area is formed above uniformly distributed comb, is improved
Contact duration of the desulfurizing agent with S02 promotes reaction efficiency；
3. desulfurizing agent is arranged below desulfurization tower bottom, smoke inlet assists adding mouth, desulfurizing agent source is the desulfurization in warehouse
Treated secondary use that agent is recovered.Venturi principle is utilized again herein, using clean flue gas by the desulfurization of secondary use
Agent imports desulfurizing tower, by upper spray mode, forms cross-flow with inlet flue gas and mixes, not only carries out secondary use, section to desulfurizing agent
About operating cost, and exacerbate the efficiency of reactive absorption, it ensure that desulfurization effect.
Detailed description of the invention
Attached drawing 1 is the schematic diagram of device；
Wherein, 1. gas inlet flue, 2. gas inlet trunnions, the main adding mouth of 3. desulfurizing agents, the flaring of 4. gas inlets, 5. desulfurization
Tower, 6. uniformly distributed combs, 7. exhanst gas outlets, 8. warehouses, 9. clean flue gas entrances, 10. 2 auxiliary trunnions, 11. desulfurizing agents auxiliary
Adding mouth, 12. 2 auxiliary flarings.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1: referring to Detailed description of the invention present embodiment, a kind of turbulent closure scheme formula sintering machine cigarette described in present embodiment
Air drying desulfurizer, including the main adding mouth 3 of gas inlet flue 1, desulfurizing agent, desulfurizing tower 5, uniformly distributed comb 6, exhanst gas outlet 7,
Warehouse 8, clean flue gas entrance 9, desulfurizing agent assist adding mouth 11, further include that flue gas is arranged in enter the gas inlet trunnion 2 before tower
With gas inlet flaring 4, the main adding mouth 3 of desulfurizing agent is arranged at gas inlet trunnion 2, and the uniformly distributed setting of comb 6 is de-
Inside sulphur tower, and before exhanst gas outlet 7.
The desulfurization tower bottom is additionally provided with clean flue gas and enters the secondary auxiliary trunnion 10 before tower and secondary auxiliary flaring 12,
The desulfurizing agent auxiliary adding mouth 11 is arranged at secondary auxiliary trunnion 10.
Specific workflow are as follows: after flue gas flows through gas inlet flue 1 according to normal flow, accelerate into gas inlet larynx
Turbulence effect occurs for pipe 2, while desulfurizing agent enters gas inlet trunnion 2 by the main adding mouth 3 of desulfurizing agent, with flue gas carry out into
Row is sufficiently mixed, and is entered desulfurizing tower 5 by gas inlet flaring 4 later, is further exacerbated by turbulent closure scheme, in the process, is taken off
SO in sulphur agent and flue gas2It is come into full contact with, and desulphurization reaction occurs, by SO2It is solidificated in desulfurizing agent surface；Flue gas is in desulfurization
It is flowed from bottom to top in tower 5, at uniformly distributed comb 6, because of the variation of air flow path and flow velocity, violent turbulent flow effect occurs for flue gas
It answers, promotes the reaction efficiency of desulfurizing agent and SO2 again, while free settling is entered warehouse 8 by bulky grain desulfurizing agent；Desulfurization later
Flue gas enters next step purification process by exhanst gas outlet 7 afterwards；
Meanwhile in 5 bottom of desulfurizing tower, adding mouth 11 is assisted by clean flue gas entrance 9, secondary auxiliary trunnion 10 and desulfurizing agent,
Desulfurizing agent after purified treatment and screening is imported into desulfurizing tower 5 again, so that desulfurizing agent is reused, and into
The desulfuration efficiency of one step enhancing integral device.
