A kind of processing method of the desulfurization fume total system, including:The desulphurization during combustion process of boiler components is done The dry dust removal process of formula deduster, the waste heat heat transfer process of heat recovery heat exchanger, desulfuration absorbing tower desulfurization absorption process, The phase transformation dust removal process of phase transformation deduster and the flue gas heat exchange process of flue gas heat-exchange unit;
The desulphurization during combustion process:
It adds fuel on burning web, closes sealing cover, block rotation snap-gauge, added by water injection pipe into the first water tank Enter suitable water, light fuel, start motor, motor drives wind turbine to start to work, and fuel combustion is in the first water tank Water is heated, and the first pump motor drives the first water pump to start to work, and hot water from the first water tank is extracted out, is transported to needs The position used, the flue gas of burning enter filtration tank by ventilation duct and are filtered, and carry out desulfurization by desulfurization disk later, finally It is discharged by downtake pipe;
The dry dust removal process:
After startup air inlet fan by dust-laden exhaust gas introduce dust cleaning case in, dust-laden exhaust gas out of economizer by when, economizer energy Flue gas low-temperature corrosion is effective against, flue gas enters the electricity behind dust cleaning case inside between positive plate and negative plate from the first air inlet pipe He Qu passes through, and the dust in flue gas bonds absorption on positive plate and negative plate under the action of charge, while high voltage electricity is broken The molecular structure of hydrocarbon and oxynitrides in bad flue gas, removal wherein peculiar smell, the flue gas after dedusting is through making a living Property charcoal strainer filtering again after discharge outdoor, the dust content in dustiness monitoring probe detection dust-removing waste gas, it is examined to be It is no to meet emission request;
The waste heat heat transfer process:
By purified treatment and the flue gas with heat enters heat exchanger body interior by flue, the second water pump and the Two pump motors work, and the water in the second water tank is extracted out from the first water inlet pipe, into the heat exchange copper tube in heat exchanger main body, Flue gas with heat carries out heat exchange with heat exchange copper tube, and heat exchange copper tube transfers heat to internal water, and water passes through return pipe Into in the second water tank, the water in heat exchange copper tube circulates, make waste heat recovery in flue gas more fully, in the second water tank Temperature sensor is provided with, when the water temperature in the second water tank is higher, is in time discharged hot water, injection cold water continues cycling through;
The desulfurization absorption process:
The flue gas of desulfurization is needed to be entered after potass pool by the 4th air inlet pipe and carries out first grade desulfurizing processing, delivery pump can be with The buck in potass pool is regularly replaced, improves desulfuration efficiency, the flue gas by preliminary desulfurization disperses by spiral board and baffle plate Afterwards, the further desulfurization process of carry out of the doctor solution sprayed using atomizer, the desulfurization fume after double action are removed into mistake Outside is discharged to after the effect of day with fog, completes the desulfurization process to flue gas;
The phase transformation dust removal process:
Pending flue gas is passed through in deduster body by the second air inlet pipe, and second exhaust pipe will handle the flue gas row completed Go out and carry out subsequent processing, capillary collects the particulate matter after phase transformation cohesion, and radiator-grid discharges the heat of the heating surface of cooling piece To the external world, phase transformation after cooling piece is cooled down the steam in the flue gas in deduster body by chill surface, and in flue gas It condenses on fine particle, is collected later by capillary, so as to achieve the purpose that dedusting;First temperature sensor obtains remove in real time Temperature information in dirt device body simultaneously returns to the second control host, and temperature information is transferred to third and shown by the second control host Real-time display on screen, while the second control host compares temperature information and default cryogenic temperature value, when temperature information is with presetting When cryogenic temperature value is identical, the second control host computer control cooling piece steady operation, so as to keep the phase stablized in deduster body Temperature environment;
The flue gas heat exchange process:
Flue gas after the discharge heat exchange of second air outlet pipe, third air inlet pipe enter flue gas to be exchanged heat, and outlet pipe discharge has exchanged heat Into heat transferring medium, the second water inlet pipe by heat transferring medium be sent into circulation pipe in, second temperature sensor obtains water outlet pipe part in real time The temperature information of heat transferring medium simultaneously returns to third control host, and temperature information is transferred to the 4th display screen by third control host Upper real-time display, while third control host computer control temperature information is compared with default heat-exchange temperature, and passes through control pressurization The flowing velocity of the power control cycle intraductal heat exchange medium of pump, control temperature information are identical with default heat-exchange temperature value.
The beneficial effects of the present invention are:
Structure, the principle of the present invention is simple, by sharing out the work and helping one another for various pieces, realizes at the perfect desulfurization to flue gas Reason, the advantages of high treating effect, each section be:
The present invention boiler components it is simple in structure, it is easily manufactured, it is easy to operate, it is multiple functional, can realize flue gas ash removal, The functions such as desulfurization, and smoke comprehensive processing is higher with boiler automatic degree, can carry out automatically controlling and monitor on-line, pole The big labor intensity for reducing worker, reduces the pollution to environment;
The present invention is removed dust by the adsorption capacity that charge generates, and improves dust removing effects, while can remove in flue gas Peculiar smell, improve gas cleaning ability, reduce environmental pollution;
The present invention deduster in, be provided with adsorption layer made of activated carbon, can to the impurity in smog and gas into Row adsorption filtration, while be provided with ultraviolet generater can send out ultraviolet light and carry out disinfection to flue gas sterilization processing, enrich The use function of air-introduced machine, while be provided with air velocity transducer, the real-time air speed value of wind-force at discharge pipe can be obtained and show It observes and understands for user on a display screen, it is easy to use;
The heat recovery heat exchanger of the present invention is simple in structure, easily manufactured, can preferably utilize the waste heat of flue gas, heat Utilization rate is higher, and existing resource is adequately and reasonably utilized, and has higher economy;
