Description
Technical field
The invention belongs to environmental protection and energy saving and fume treatment technical fields, and in particular to one kind is suitable for smoke-gas wet desulfurization and inhales
The flue gas for receiving tower takes off white device and flue gas takes off whitening method.
Background technique
90% or more unit of China's Desulphurization for Coal-fired Power Plant facility is all made of one gypsum wet sulfur removal technology of lime stone at present, takes off
Flue-gas temperature after sulphur is down between 45 DEG C~60 DEG C, and the water capacity of the flue gas come out at this time is substantially at saturation state.Desulfurization
Saturation wet flue gas afterwards is discharged, into the lower environment of temperature by chimney, and the water vapour in flue gas can condense into fine droplet shape
At wet plume.Environment temperature is lower, humidity is bigger, and drop agglomeration effect is bigger, and white plume is longer, this is also current all wet
The all existing universal phenomenon of method desulfurization.Not only perception is bad for the plume of formation, and a large amount of water vapours are also contained in flue gas, and water steams
Contain more dissolubility salt, SO in vapour3, gel dust, micronic dust etc., these are all the main components of haze, direct by chimney
Discharge, to ambient enviroment, there is also certain pollutions.
In recent years the local governments such as Jiangxi, Hebei, Zhejiang, Shanxi put into effect flue gas successively and take off white policy, standard, administer requirement.
Some Domestic steel sintering machine, coking, coal-burning power plant etc. have responded policy and have called and complete gypsum rain and the improvement of coloured plume
Engineering.Due to the difference of south and north, east and west region, weather conditions differ greatly, for example mean temperature, humidity, extreme temperature difference are very
Greatly, the method and technology of use is also not quite similar.Different, residual heat resources difference that there are also the process flow conditions of each enterprise, investment are wanted
Ask different, the desulfurization fume taken disappears the factors such as whitening method difference, and process program is ever-changing and has very big difference, but meets
User's requirement is the fundamental requirement of technical solution.The mechanism for being formed and being dissipated according to wet plume, currently used method are concluded are as follows:
Flue gas technology, flue gas condensing technology, flue gas first condense the combination technique of thermal technology again and various methods.
Currently used flue gas condensing thermal technology again are as follows: water-cooled condenser is arranged in desulfurization exhaust pass, and condenser shell side is walked
Flue gas, tube side walk recirculated cooling water, achieve the purpose that cool-down dehumidification by heat exchange；Steam heater is set before smoke stack emission,
Heater shell side walks flue gas, and tube side walks cyclic steam, achievees the purpose that heating by heat exchange.Entire flue gas condensing reheat machine system
System process are as follows: the saturation wet flue gas that desulfurizing tower comes out, by cool-down dehumidification, re-forms one compared with low temperature after water-cooled condenser
Saturation wet flue gas.Part steam in flue gas is removed, and in the condensation of flue gas condenser heat exchange surface, whereabouts, generation is coagulated
It bears water and is recycled.It is sent via power transmission equipment to air cooling compressor and cools by the recirculated water of flue gas, drop
Recirculated water after temperature returns water-cooled condenser again, so recycles.Recirculated water serves as coolant media in the process.Before chimney out,
Saturation wet flue gas after cool-down dehumidification compared with low temperature is raised to after steam heater heats under conditions of water capacity is constant
After assigned temperature, flue gas becomes unsaturated state from saturation state.Finally reach elimination " white cigarette " effect in flue gas outlet.
From the point of view of traditional flue gas condensing again thermal technology and process, water cooling condenser system is in addition to capital equipment flue gas condenser
Except, there are also matched cooling water system and powertrain systems.Lead to that entire flue gas condensing system footprint is big, investment is made in this way
The immediate problems such as valence height.Along with power consumption, water consume and the flue gas heating system during water-cooled condenser operation use the consumption of steam
Amount, normally will also generate a no small operating cost over a year.Therefore, seek a set of land occupation less, system is simple, running cost
It is very necessary that white processing equipment is taken off with low smoke-gas wet desulfurization (WFGD) chimney.
Natural gas is the high-efficiency cleaning energy, since the 1980s, China's natural gas proved reserves and sustained production
Rapid growth.As all fronts of the pipelines such as transfering natural gas from the west to the east, river gas east are sent, the second west to east gas pipeline project are constructed and put into operation, three lines of transferring natural gas from the west to the east
West section, An Nanduan, eastern section, Changsha branch line are constructed and put into operation, and the gas distributing system in a covering whole nation is gradually forming.With
China's metallurgy, tubulation, welding and other construction technologies progress, for improve gas transmission ability, increase economic benefit, gas pipeline is not
Break and develops to Large Diameter Pipeline, high pressure and other new material new technology directions.Currently, the long-distance conveying of China's pipe natural gas, greatly
Mostly use the mode that high-voltage tube is defeated.Natural gas upstream is sent by high pressure pipe network to each city or large-scale user, natural by various regions
Gas voltage regulating station is depressurized to middle pressure or low pressure is sent to user and used, and pipe network generates a large amount of pressure energies in pressure reduction, pressure energy
Recycling is important link during natural gas transmission and distribution.By taking West-East National Gas Transmission Project as an example, high-pressure natural gas need to be dropped by 10MPa
It is even lower to 2MPa~4MPa, and the pressure that end user uses is about 0.4MPa, according to reckoning, gas pressure is by 4MPa
Being down to the recyclable maximum pressure of 0.4MPa can be about 322kJ/kg, with 120 × 108m3The displacement of/a calculates, annual such
The recyclable maximum pressure of pipe network can be about 3.5 × 1012kJ.If so big potential energy waste be bound to cause it is huge
Economic loss.If can be recycled to this, very far-reaching influence will be generated to China's energy industry, be provided for reducing
Source waste, Accelerating The Construction resource-conserving and environment-friendly society have great importance.
