Abstract
The utility model is suitable for a small -size unit of municipal heat supply that the environmental protection was had relatively high expectations to the fume emission relates to a wet method flue gas desulfurization tower export flue gas dust removal, heating integrated device, it includes the condensation tube bank of following flue gas export orientation and setting gradually, mechanical defroster and heat dissipation tube bank its characterized in that, form the refrigeration, heat the circulation system through compressor and choke valve between condensation tube bank and the heat dissipation tube bank. The utility model discloses utilize the function that heats, refrigerates in the air conditioner principle simultaneously, make the heat in the upstream and downstream flue gas pass through refrigerant emergence migration transmission to at flue gas condensation, mechanical defogging in -process, effectively get rid of partly smoke and dust, finally make the flue gas obtain purifying and the heating, satisfy higher environmental protection requirement.
Description
Technical field
This utility model is related to a kind of wet flue gas desulfurization tower exiting flue gas dedusting, heater, it is adaptable to which flue gas is arranged
Put the higher city heat supply small unit of environmental requirement.
Background technology
Overwhelming majority Desulphurization for Coal-fired Power Plant adopts wet processing at present, in wet desulfurizing process, absorption tower outlet cigarette
Gas reaches steam-laden, exports in smoke stack emission, and as winter atmospheric temperature is significantly lower than flue-gas temperature again, therefore chimney goes out
The white haze of mouth clearly, occurs chimney rain when serious（Below chimney white haze, there are obvious water droplet landing, following mao mao
Rain is general）.The acidity of chimney rain is stronger（PH value 2 ~ 3）, the environment near meeting severe contamination chimney, if periphery has resident, also
Conflict can be caused.In addition, in recent years, environmental requirement more and more higher of the country to boiler emission air, it is desirable to be done step-by-step ultralow
Discharge, wherein dust concentration emission request reach 10mg/Nm3Below.Instantly near cities（Particularly it is that periphery has resident）For
Heat engine group, in order to dust concentration is up to standard, can adopt wet electrical dust precipitator；In order to eliminate chimney rain, mitigate chimney white haze phenomenon,
Flue gas heater can be adopted（There are individual power plants to heat using steam）Or heat exchanger, this two conventional measures it is costly,
And fabricating yard is required than larger.And some units, desulfurizing tower is very narrow to the place between chimney, it is impossible to while installing wet
Formula electric cleaner and flue gas heat-exchange unit.
The content of the invention
The purpose of this utility model is to provide a kind of wet flue gas desulfurization tower exiting flue gas dedusting, heating integrating device.
Main technical schemes of the present utility model：Wet flue gas desulfurization tower exiting flue gas dedusting, heating integrating device, which is special
It is that it includes that the condensation tube bank set gradually along exhanst gas outlet direction, mechanical demister and radiating are restrained to levy, the condensing tube
Pass through compressor between beam and radiating tube bank and choke valve forms refrigeration, heats circulating system.
It is of the present utility model to focus on while heating in using air-conditioning principle, refrigerating function, in making upstream and downstream flue gas
Heat there is migration transmission by cold-producing medium, and during flue gas condensing, mechanical demisting, effectively remove a part of flue dust,
Flue gas is purified and is heated, meet higher environmental requirement.
Description of the drawings
Fig. 1 is this utility model embodiment wet flue gas desulfurization tower exiting flue gas dedusting, the connection of heating integrating device is shown
It is intended to.
In figure, 1- compressors；2- radiating tube banks；3- choke valves；4- condensation tube banks；5- machinery demisters.
Specific embodiment
This utility model is described in detail in reference to embodiment and accompanying drawing.
Embodiment：Wet flue gas desulfurization tower exiting flue gas dedusting, heating integrating device refer to the attached drawing 1, are mainly included along cigarette
Condensation tube bank 4, mechanical demister 5 and radiating tube bank 2 that gas Way out sets gradually, the condensation tube bank 4 and radiating tube bank 2
Between pass through compressor 1 and choke valve 3 and form refrigeration, heat circulating system.
When embodiment is run, gaseous refrigerant medium Jing compressors 1 compress, and are changed into high-temperature liquid state, through radiating tube bank 2, make
Tube bank outside flue gas is heated, and liquid medium is cooled down；Through choke valve 3, liquid medium is released due to pressure, by
Liquid is changed into gaseous state, and in this phase transition process, medium temp declines suddenly, and cryogenic gaseous media flow crosses condensation tube bank 4, makes tube bank
Outside flue gas condensed, gaseous medium again passes by compressor, complete one heat, kind of refrigeration cycle.And desulfurizing tower goes out saliva
Vapo(u)rous flue gas produces big droplet by condensing during tube bank with the dust in flue gas, fine mist to condense core, these
Big droplet is removed through mechanical demister, and the droplet content in flue gas returns to tower exiting flue gas droplet content, in mechanical demisting
In the droplet that device is removed, comprising considerable amount of flue dust, therefore flue dust obtains further effectively removal.Last demister outlet cigarette
Gas by radiate tube bank, heated flue-gas temperature, the flue-gas temperature after heating apparently higher than（More than 10 degrees Celsius）Water steams
Gas saturation temperature, the flue gas after such smoke stack emission is not in chimney rain, and flue gas white haze also mitigates significantly.
The present embodiment integrating device, while heating in using air-conditioning principle, refrigerating function, make the heat of flue gas stream upstream and downstream
Amount is migrated（By cold-producing medium medium）, realize further dedusting, the heating function of flue gas after desulfurization.Due to radiating tube
Beam, condensation tube bank, taking up room for mechanical demister at most only have three molecules one of wet electrical dust precipitator, the expense of engineering construction
Also below wet electrical dust precipitator, therefore there is on urban small thermal power plant unit good technology economy advantage.
