Description
Technical field:
The present invention provides a kind of SO2Minimum discharge micro-alternating temperature energy-saving and smoke-removing system, belongs to resource environment flue gases purification neck
Territory.
Background technology:
Along with thermal power plant's atmosphere pollution controls to enter the minimum discharge stage, thermoelectricity SO 2 from fume concentration of emission controls
Require the 200mg/m from standard GB/T 13223-20113It is down to 35mg/m3Hereinafter, namely minimum discharge, some areas are marked
Standard even requires to take measures to eliminate plume.At present, the conventional limestone desulfurization of gypsum technique of application uses single column spray single
PH value controls, and desulfuration efficiency is generally 95%, relies on simple amplification conservative design, has been difficult to meet new emission control and has wanted
Ask, and use merely conservative design to exist and build and run uneconomical, the problems such as adaptability for working condition is poor.About eliminating plume,
The swinging GGH heat transfer technology originally used is because equipment leaks out, SO2The problems such as escape, fault rate height, the most basic
Eliminate, and because Air Leakage is difficult to meet minimum discharge demand.And tradition directly reheating technology heating power consumption is high, also increase cigarette wind
SR, increases unit air-introduced machine power consumption, less economical.Therefore, can meet super by high-efficiency desulfurization in the urgent need to exploitation one

SO of the present invention2The concrete function of minimum discharge micro-alternating temperature energy-saving and smoke-removing system components is as follows:
1, the micro-alternating temperature of the double pH spray desulfurizing towers energy-conservation discharge smoke depressant systems of the present invention is applied in combination with desulfurizing tower inner member,
First passing through one-level demister tentatively except mist, initial gross separation spraying layer serosity carries；Followed by cooling current equalizer, (phase varying depth is clean
Change device) cooling, phase transformation, the trickle droplet of cohesion, fine particle, condensation steam, precipitation flue gas in substantial amounts of water；Then two grades are utilized
Demister dedusting, except after mist, flue gas becomes the ultra-clean flue gas containing a small amount of saturation vapour, had not only improved the flow field of desulfurizing tower, but also had carried
The demisting efficiency of demister, absorption tower outlet droplet content 5～25mg/m in high desulfurizing tower3, inhale far below conventional demister
Receive tower trickle serosity droplet carrying amount 75mg/m3；Recycling slight fever heating device adds heat smoke and becomes unsaturated gas, eliminates the need for
Plume, gypsum rain, white cigarette be can't see by chimney.
2, cooling current equalizer has waste heat recovery, flow field, homogenizing absorption tower, reduction absorption tower processes exhaust gas volumn, reduction takes off
The function of sulfur water consumption.Eliminate smoke for the heating of absorption tower flue gas after desulfurization by reclaiming the waste heat in the entrance dry flue gas of absorption tower, remaining
Heat utilization, does not increase smoke elimination energy consumption；Reducing into tower flue gas temperature, the operating mode exhaust gas volumn that absorption tower processes declines, extends
Flue gas is the time of staying of scrubbing section in absorption tower, is beneficial to improve desulfuration efficiency, decreases absorption tower water evaporation amount, reduces
Desulphurization system water consumption.
3, phase transformation deep purifier has fine particulates and droplet cohesion, multi-pollutant deep purifying, dehydrating function, logical
Supercooling medium carries the supersaturation wet flue gas cooling of a certain amount of serosity droplet through one-level demister except mist to after desulfurization
With generation phase transformation, promote fine particle and droplet phase transformation cohesion, condense oversaturated flue gas, produce a large amount of removable drop, logical
Cross phase transformation deep purifier and follow-up two grades of demister removings, by water a large amount of in flue gas and pollutant removing.
4, slight fever intensification smoke eliminator utilize waste heat that absorption tower inlet flue gas reclaims by after desulfurization through deep purifying and de-
Water saturation wet flue gas microlitre temperature so that flue gas enters the most thorough white cigarette of vision eliminated of discharge behind unsaturated district.
5, wall stream draining ring deflects from absorbing tower wall for the serosity that upper strata sprays wall built-up, imports to alms bowl type drip tray,
It is assigned to wall built-up liquid film vibrate on separatory ring simultaneously, is again torn by vibration separatory ring cut by vibrating the serosity confluxed by wall built-up
Rupture and be dispersed into drop for flue gas washing, to improve the effective liquid-gas ratio of desulfurization.
6, vibration separatory ring is to be connected to the inner side that upper and lower two arc rings engage junctions to open the alloy thin layer of strip tooth mouth,
Inner generation under the impact of air-flow and spray droplet is shaken, and the serosity under along wall stream is torn into scattered drop.Vibration
The material of separatory ring can use alloy, carbon steel cover antiseptic wearable coat, can also use anticorrosive anti-wear non-metallic material (as
Fiberglass), vibration source is that the impact of air-flow, liquid stream or whereabouts serosity causes.
7, alms bowl type drip tray: in alms bowl body streamline construction, open topped, for collecting the serosity that high pH scrubbing section gets off,
Bottom connects serosity pipeline, the high pH serosity collected is derived the high pH stock tank outside absorption tower, thus low pH starches with in absorption tower
Being effectively isolated of pond, it is achieved double pH value control partition function.The Streamline Design of alms bowl type drip tray is conducive to cigarette from below to up
Gas rounding off and shunting, reduce the resistance that flue gas is through-flow to greatest extent.Airflow design any surface finish simultaneously is available saturated
