Description
Technical field
The invention belongs to energy-conserving and emission-cutting technology fields, and in particular to a kind of system and method for the white tail that removes smoke.
Background technique
Coal-fired plant flue gas is discharged into atmosphere through chimney, because of the reasons such as sky background color and skylight photograph, viewing angle, vision
Upper is usually white, grey, blue etc., is become " coloured plume ", however passes through the continuous development of energy-conserving and emission-cutting technology, at present
" coloured plume " is mainly relatively conventional with " white plume ".
China's major part coal fired generator set desulfurization system (it is de- to call wet process in the following text using Limestone-gypsum Wet Flue Gas Desulfurization Process technique
Sulphur), which can make flue-gas temperature be reduced to 45~55 DEG C, these low temperature are saturated wet flue gas and directly enter big compression ring through chimney
Border condenses into fine droplet to the cold, to generate " white plume ".
Wet desulfurizing process is with its desulfuration efficiency height, and operating cost is low, technology maturation, runs the advantages such as easy to operate in cigarette

It reduces.After flue gas reaches saturation state, part droplet can be carried.The saturation wet flue gas for carrying droplet is removed by demister
Atmosphere is discharged into after partial drop, since environment temperature is lower than flue-gas temperature, the hydrogenesis droplet being saturated in wet flue gas, flue gas
Eventually by smoke stack emission into atmosphere, the white flue gas being discharged into atmosphere leaves apparent tail in the sky, is formed " white
Color plume ".And flue gas water content of combustion of natural gas itself is significantly larger than the water content of coal-fired flue-gas, even if not fired to natural gas
The flue gas of burning implements wet desulphurization, when exhaust gas temperature reduces, also will form apparent " white plume ".Environment temperature is lower,
Ambient humidity is bigger, " white plume " is longer.
The white of flue gas is the formation of vapor contained in flue gas, and white flue gas water mist is not only to cause atmospheric haze dirty
One of origin cause of formation of dye and surface water resources are evaporated to one of the approach for causing water resource largely to waste in atmosphere, or a kind of
City visual pollution.In order to eliminate white flue gas tail, someone, which has invented, to take water of river and lake and cools down cigarette indirectly by heat exchanger
Gas or the system that flue gas is directly sprayed without heat exchanger, also someone, which has invented, passes through heat exchanger indirect heating flue gas using steam
System or system that heat exchanger indirect heating flue gas is directed or through using high-temperature flue gas, still, these methods all can not
It to consume a large amount of electric power and heating power or consumption great lot of water resources with avoiding, not meet energy-saving developing direction, these methods
Investment is big, operating cost is high, and also infeasible in the occasion for lacking low-temperature water source or scarce high temperature heat source.

Receipts formula heat pump weak solution 2-3, the water evaporation in absorption heat pump weak solution 2-3 is come out, and the vapor being evaporated is to absorb
Formula heat pump fluid steam 2-7, absorption heat pump working substance steam 2-7 enter compression heat pump condenser 2-2, and steam discharges heat
To becoming condensed water in high temperature 2-8, heat of the condensed water in high temperature 2-8 in flue gas cool-down unit 2-1 in expansion absorption flue gas after flue gas
Amount, flue gas discharge thermal temperature reduction in flue gas cool-down unit 2-1, and the steam after then expanding enters absorption heat pump absorption
Device 2-2-1 is absorbed formula heat pump concentrated solution 2-5 absorption, forms absorption heat pump weak solution 2-3, pass through absorption heat pump solution
It pumps 2-4 and returns to absorption heat pump generator 2-6 cycling and reutilization, absorption heat pump drive energy 1-1 occurs in absorption heat pump
After rejecting heat to absorption heat pump weak solution 2-3 in device 2-6, after-heat can also continue to it is cold from heat pump for heating
The flue gas 3-3 being discharged in condenser 2-2-2 enters atmosphere, more through smoke stack emission again after further increasing the temperature of flue gas 3-3
Added with the white tail for helping remove smoke.

2-14 work, driving heat pump 2 work, and when heat pump 2 works, compression heat pump gaseous expansion working medium 2-10 compresses 2-14 by heat pump
Compression, becomes compression heat pump high pressure gaseous working medium 2-13, in flue gas unit 2-2, high temperature and pressure working medium 2-13
By compression heat pump condenser 2-2-3, hot fume 3-2 to be added is transferred heat to, becomes compression heat pump cryogenic high pressure liquid
Body working medium 2-12, the heat that hot fume 3-2 to be added absorbs liquid high temperature refrigerant in heat pump condenser 2-2-3 are heated to form height
Warm flue gas 3-3, the flue gas 3-3 being heated up, which is discharged into atmosphere, does not have white cigarette, and cryogenic high pressure liquid refrigerant 2-12 is through over-voltage
After contracting formula heat pump expansion valve 2-11, cryogenic gaseous working medium 2-10 are expanded into, in flue gas cool-down unit 2-1, cryogenic gaseous working medium
2-10 absorbs the heat of flue gas 3-1 to be processed, after flue gas 3-1 transfers heat to gaseous working medium 2-10, flue gas 3-1 temperature drop
Low to become low-temperature flue gas 3-2, temperature increases after gaseous working medium 2-10 absorbs the heat of flue gas 3-1 to be processed, enters back into heat pump pressure
Contracting machine 2-14, heat pump fluid enter new round circulation, during flue gas 3-1 cooling becomes flue gas 3-2, while in flue gas
Water condensation be precipitated, condensed water 4 be condensed water recovery unit recycling, saving water resource can be recycled, the amount of condensed water 4 is equal to
Water contained in flue gas 3-1 to be processed subtracts water contained in the flue gas 3-3 after cooling, the water condensation in flue gas
In the process by flue gas fine particle pollutant and soluble pollutants take out of, make to be ultimately discharged into the flue gas 3- in atmosphere
3 more clean cleaner, the flue gas 3-2 after cooling and dewatering in advance, and when becoming flue gas 3-3 after reheating, flue gas 3-3 is no longer
It is white smoke, but colourless flue gas, it is finally discharged into atmosphere from chimney, white flue gas tail disappears.
