When ambient temperature is relatively low, relative humidity is larger, high-temperature flue gas from chimney be discharged to ambient condition when, due to flue gas temperature
Degree is reduced, and the moisture in flue gas is in hypersaturated state, is condensed into droplet and forms white cigarette.The most fundamental way of removing white cigarette
That the moisture in partial fume is removed before fume emission, the removal of current flue gas moisture mainly by multistage wet method tower, first
Sour gas used in level wet method tower in alkali liquor (such as NaOH solution) removing flue gas, spraying water in the wet method tower of the second level is carried out
Flue gas cool-down is so that hydrogenesis in flue gas.For the current wet method tower for removing moisture in flue gas, second level tower
The hydrogenesis in flue gas, recirculated cooling water are caused to need by extra heat exchanger and cooling using circulation spray cooling mode
Tower is exchanged heat, and equipment is complicated, needs to increase extra equipment investment, power consumption and water consume.
For this purpose, this utility model provides a kind of device for removing chimney breast white cigarette, described device includes connecting from bottom to top
Logical first order treating column and second level treating column, flue gas remove sour gas in the first order treating column, described
Fully heat exchange is carried out in two stage treatment tower with high-efficiency fin pipe heat exchanger to remove moisture.
This utility model is lowered the temperature to flue gas using high-efficiency fin pipe heat exchanger, is recirculated water on the inside of Tube Sheet of Heat Exchanger
Path is directly connected to outside cooling tower, is fin to increase heat exchange area on the outside of Tube Sheet of Heat Exchanger, accelerates the cooling of flue gas.This practicality
New utilization high-efficiency fin pipe heat exchanger simplifies the structure of wet method tower second level dehumidification part, reduce equipment investment into
This, while equipment power consumption and water consume are reduced, with obvious economic benefit and environmental benefit.
As shown in figure 1, the device of removal chimney breast white cigarette that this utility model is provided include connecting from bottom to top the
Coagulation tower and second level treating column.Flue gas from incinerator or other boilers is via positioned at first order treating column
The smoke inlet 1 of bottom enters first order treating column, through alkali liquor (such as NaOH solution) removing acid in first order treating column
Property gas.First order treating column is configured with alkali liquor circulation line 2, and alkali liquor is via the shower nozzle for being arranged at first order treating column internal upper part
3 spray, and the alkali liquor for flowing downward is fully contacted with the flue gas for flowing up and is mixed, effectively to remove the sour gas in flue gas,
Flow the alkali liquor of the bottom of towe Jing Jing after water pump supercharging and the top of tower is returned to recycle by alkali liquor circulation line 2.At the first order
Li Tanei is also configured with demister 4, and demister 4 is arranged between the entrance of shower nozzle 3 and second level treating column, is taken with removing flue gas
The part steam of band.
Through the deacidification process after flue gas from the top of first order treating column enter second level treating column, flue gas to
Fully exchanged heat with high-efficiency fin pipe heat exchanger 8 during upper flowing.Recirculated cooling water from cooling tower is via height
The entrance 6 of effect fin-tube heat exchanger 8 is cooled down into high-efficiency fin pipe heat exchanger 8 to flue gas, and the moisture in flue gas coagulates
Drain pipe 5 after knot by being arranged on the treating column lower sides of the second level enters water treatment facilities, absorbs following for flue gas heat
Ring cooling water returns to cooling tower cooler via the outlet 7 of high-efficiency fin pipe heat exchanger 8, deviates from the flue gas after moisture through demisting
Further heating for device 4 enters atmospheric environment via the exhanst gas outlet 9 at the top of the treating column of the second level.Most of moisture in flue gas
It has been removed, has entered the flue gas in atmospheric environment and will not form white cigarette, so as to realizes that chimney takes off white effect.
By turbidity, oxygen consumption COD in the condensation waste water that drain pipe 5 is dischargedcr、TDS、BOD5、NH3- N, nitrate, sulphuric acid
Standard of the content of material such as salt, ferrum, manganese beyond reutilization of the sewage in GB19923-2005, it is impossible to realize reuse, Er Qieruo
Directly discharge will necessarily cause the pollution of environment, while causing the waste of resource.As an example, process the water of the condensation waste water
Regulating reservoir that processing equipment includes being sequentially communicated, pH regulator pond, oil water separator, biochemical Aerobic Pond, coagulation-flocculation pond, precipitation
Pond, filter, heat exchanger processing system, reverse osmosis treatment system and sterilization pool.
The regulating reservoir is used to improve the buffer capacity to organic loading, prevents the drastically change of processing system load,
To ensure the normal operation of Waste Water Treatment.The pH regulator pond is used for control ph, and the condensed water is adjusted to alkalescence,
To reduce the consumption of the chemicals that neutralization needs.The oil water separator is used for regulating pondage air blast, with advance to the dirt
The profit layering in sewage, then air supporting removing oil are realized in water oxygenation simultaneously.The biochemical Aerobic Pond is for carrying out to the sewage
Continuous aerobic biochemical, to remove the Organic substance in the sewage.The coagulation-flocculation pond by compression double electric layer, adsorption bridging,
The granule for being difficult to Direct precipitation is wadded a quilt with cotton into big precipitable granule by the effect that absorption charge neutrality precipitate net is caught, and reaches primary water
The purpose of matter.The sedimentation tank is precipitated and is separated for the pollutant of flocculation cohesion in the coagulation-flocculation pond are formed.It is described
Filter is used for float and the baregin granule gone in eliminating water, to reduce the turbidity of water.The heat exchanger processing system is used for
The condensed water is heated, the temperature of the condensed water is improved, follow-up reverse osmosiss effect is improved.The reverse-osmosis treated system
Unite for removing the various ions in condensed water, to reach the corrosivity that the condensed water is reduced while emission request.It is described
Sterilization pool for the condensed water is carried out disinfection and is decolourized, to carry out reuse or discharge.
This utility model provides the device of removal chimney breast white cigarette and has advantages below：
(1) second level treating column is not provided with spray cooling equipment so that the structure of second level treating column simplifies；
(2) directly flue gas is lowered the temperature using high-efficiency fin pipe heat exchanger, saves external heat exchanger equipment, to flue gas
The system lowered the temperature only includes high-efficiency fin pipe heat exchanger and cooling tower two parts, saves occupation area of equipment, lowers
System complexity, while the power consumption and water consume when the equipment of reduction runs, can solve chimney with relatively low investment and operating cost
Emit the problem of white cigarette.
This utility model is illustrated by above-described embodiment, but it is to be understood that, above-described embodiment is
For citing and descriptive purpose, and it is not intended to this utility model is limited in described scope of embodiments.In addition ability
Field technique personnel it is understood that this utility model is not limited to above-described embodiment, according to teaching of the present utility model also
More kinds of variants and modifications can be made, these variants and modifications all fall within this utility model scope required for protection with
It is interior.Protection domain of the present utility model is defined by the appended claims and its equivalent scope.
