Description
Technical field
The present invention relates to plate type heat exchanger technical field, and in particular to a kind of flue gas heat-exchange unit with defrosting function.
Background technology
In the production process of the industries such as petrochemical industry, electric power, waste incineration, burning heater is often used, and
Often contain SO in flue gas caused by these burners2Deng corrosive gas, it is necessary to using technologies such as wet desulphurizations come to cigarette
Gas carries out integrated treatment.Wet flue gas temperature after desulfurization is relatively low, and also substantial amounts of aqueous vapor and drop.It is often molten in these drops
Solution has substantial amounts of water soluble salt, such as sodium sulphate, ammonium sulfate, is directly discharged in air that aerosol particle can be formed,
As the arch-criminal of haze.So typically to set multi-stage demister, demisting is carried out to it.
In addition, wet flue gas vapor content is larger after desulfurization, it is several into saturation state.In cold snap, such as north of china in winter, pass through
If chimney directly discharges, dense white cigarette can be formed, causes visual pollution, it is also possible to " chimney rain " is formed, is landed in plant area,
Causing ground to freeze turns into potential safety hazard, therefore frequently with the method for wet flue gas after high-temperature flue gas heating desulfurization before desulfurization, lift cigarette
Chimney discharges flue-gas temperature, makes it be not easy to form white cigarette, so flue gas reheater is set（GGH, gas-to-gas heat exchanger）.
Furthermore during flue gas heat recovery, frequently with the method for flue gas combustion air, reclaim a part of cigarette
Gas used heat.In this process, it is combustion-supporting that burner hearth is entered after ambient air temperature rise, improves system thermal efficiency；Flue-gas temperature reduces
Enter smoke stack emission afterwards.This technical process is realized, it is necessary to set air preheater.If flue gas waste heat recovery amplitude is enough big, cigarette
Temperature degree can utilize the part latent heat of vaporization up to being reduced to below dew point.At this moment condensate liquid precipitation is also had, demisting need to be set again
Device, in order to collect condensing droplet, it is set not to be discharged into air with flue gas.
Traditional gas-gas heat exchanger has number of different types, structurally, such as swinging, bundled tube, plate-fin, plate pipe
Formula, heat pipe-type etc..Demister also has number of different types, such as wave-shaped plate demister, mesh mist eliminator, centrifugation bundled tube demister
Etc..Without exception, these heat exchangers and demister volume are all very huge, during commercial Application, often by
Restricted to space factor, so that effectiveness can not be played all, or input cost effectiveness and to take resource utilization higher, manufacturing
Many inconvenience are also had with transport installation process.
The content of the invention
It is an object of the invention to provide a kind of flue gas heat-exchange unit with defrosting function, and small volume can be most of
The equipment combination of occasion substitution " traditional gas-to-gas heat exchanger+demister ", and the cost of heat exchanger is made than traditional unit equipment
Low more of valency.
To solve the deficiency of above-mentioned technical problem, used technical scheme is the present invention：It is a kind of with defrosting function
Flue gas heat-exchange unit, including framework and the heat-exchanging component that is assembled in framework, framework are made up of upper cover plate, lower shoe and column, changed
Multi-disc heat exchange plate of the hot assembling components between upper cover plate and lower shoe, spaced Jie is formed between multi-disc heat exchange plate
The runner of matter one and the runner of medium two, two sides of the runner of medium one are respectively arranged with vertical sealing strip, two sides of the runner of medium two
It is respectively arranged with horizontal sealing strip, it is characterised in that：
Be respectively provided with the runner of medium one and medium two runner along its media flow direction set it is multiple be parallel to each other it is non-
Linear water conservancy diversion rib, water conservancy diversion rib are continuous list structure or spaced segmental structure.
As a kind of further optimization of the flue gas heat-exchange unit with defrosting function of the present invention：The water conservancy diversion rib is continuous
Waveform list structure.
As a kind of further optimization of the flue gas heat-exchange unit with defrosting function of the present invention：The water conservancy diversion rib is continuous
Fold-line-shaped list structure.
