The utility model discloses on the basis that utilizes the cold quick -witted residual heat resources of ring, promoted plume rise height after the desulfurization, has solved the desulphurization unit fume emission height of not going up GGH and has spent and lowly lead to the fact the problem of influence to the environment, reached waste control by waste's effect simultaneously, by a wide margin reduction present flue gas heat the running cost.
Description
Technical field
The utility model relates to central cooler residual heat resources and flue gas after desulfurization heats technical field of comprehensive utilization, particularly relates to the flue gas desulfur device that sintering plant, pelletizing plant etc. have clean high-quality thermal source.
Background technology
Existing oxysulfide (SO, SO
2, be called for short SO
x), be one of current topmost atmosphere pollution, be gas that is colourless, pungent, it is not only detrimental to health and plant growth, but also meeting etching apparatus, building and the scenic spots and historical sites.It is mainly from the burning of sulfurous fuels, metal smelt, petroleum refining, sulfuric acid (H
2sO
4) process such as production and silicate product roasting.Oxysulfide in waste gas mainly contains sulfur dioxide (SO
2) and sulfur trioxide (SO
3).The whole world is every year to the SO of airborne release
2be about 1.5 hundred million tons.Therefore the improvement of oxysulfide is very important, SO
2administer except employing non-pollution technology, mainly also have flue gas desulfurization, high chimney emission etc.These methods are also applicable to SO usually
3improvement.
Form and the processing procedure of absorbent or the adsorbent used are pressed in flue gas desulfurization, are divided into dry method, semidry method, wet method three major types.Current wet desulphurization possesses skills comparatively ripe, and the features such as desulfuration efficiency is high, simple to operate are widely used.But wet desulphurization, because sweetening process reaction temperature is lower than dew point, could be discharged so the flue gas after desulfurization needs to heat again.
Current GGH is one of capital equipment of being heated by neat stress after desulfurization, and neat stress heats by the former flue gas of this equipment utilization, makes exhaust gas temperature reach on dew point, to promote the height of release of flue gas.But the use of GGH adds investment and operating cost, add the energy consumption of desulfurization operation, water consumption greatly, the waste water after GGH rinses, also containing very strong corrosivity, has to pass through the process of specialty.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of Novel desulphurization Smoke-heating device, this device by the wet flue gas temperature increase introduced after clean high-temperature flue gas desulfurization to about 80 DEG C, with solve extreme weather air pressure low time cause flue gas to sink phenomenon, reduce the operating cost of flue gas.
The purpose of this utility model is realized by following technical scheme:
A kind of Novel desulphurization Smoke-heating device, comprising: central cooler, heating blower, booster fan, concrete chimney, inner steel cylinder of chimney, guiding device, absorption tower exhaust pass and condensate water recovery device;
Described central cooler is connected with booster fan with described heating blower respectively;
Described booster fan is connected with inner steel cylinder of chimney, and arranges a seal ring on the airduct connected;
Described inner steel cylinder of chimney is connected with described guiding device;
Described condensate water recovery device is arranged on the below of described seal ring.
Compared with prior art, one or more embodiment of the present utility model can have the following advantages by tool:
On the basis utilizing central cooler residual heat resources, improve flue gas after desulfurization rising height, solve the too low problem that environment is impacted of desulfurizer fume emission height not going up GGH, reach the effect of the treatment of wastes with processes of wastes against one another simultaneously, significantly decrease existing flue gas operating cost.
Accompanying drawing explanation
Fig. 1 is Novel desulphurization Smoke-heating device structural representation.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with embodiment and accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, be desulfurization fume heater structure, comprise central cooler, heating blower 1, booster fan 2, concrete chimney 6, inner steel cylinder of chimney 7, guiding device 11, absorption tower exhaust pass 8 and condensate water recovery device 12;
Described central cooler is connected with booster fan with described heating blower respectively;
Described booster fan is connected with inner steel cylinder of chimney, and arranges a seal ring 5 on the airduct connected;
Described inner steel cylinder of chimney is connected with described guiding device;
Described condensate water recovery device is arranged on the below of described seal ring.
Said apparatus also comprises variable-frequency governor 3 and baffle door 4, and described baffle door is the two louver type damper door of single shaft.
The two louver type damper door of above-mentioned single shaft includes multiple.
Above-mentioned central cooler comprises central cooler three section 9 and central cooler four section 10, described central cooler three sections exhaust delivers to inner steel cylinder of chimney by booster fan after drawing, mixed with wet flue gas after desulfurization by guiding device after entering bottom inner steel cylinder of chimney, to reach the object to wet flue gas heating.By connecting airduct and flowing backward to booster fan, corrosion injury is caused to it for preventing in chimney condensate liquid, connecting on airduct between booster fan with inner steel cylinder of chimney arranges seal ring, makes condensate liquid enter condensate water recovery device by the Drainage pipe in seal ring front and reclaims use.
After the discharged gas fume of central cooler four sections about 80 DEG C is drawn, be connected to heating blower import, enter all central coolers three sections by heating blower to promote thermal source smoke problem, improve heating blower medium entrance temperature, and then reach the object improving central cooler three sections of extraction temperatures.By about the 350 DEG C thermal source flue gases of temperature in central cooler three sections after promoting through booster fan to be transported to after desulfurization in outer smoke evacuation chimney with desulfurization fume Homogeneous phase mixing.
Above-mentioned two-part rate-of flow and temperature are regulated by variable-frequency governor and the two louver type damper door of single shaft, avoid that overheating problem occurs and cause damage to desulphurization plant.
Above-described embodiment utilizes sintering plant, the residual heat resources of pelletizing plant's ring air-cooler discharged gas fume promote the flue-gas temperature after desulfurization, has reached the height of release promoting desulfurization fume, has promoted the protection to environment.
Although the embodiment disclosed by the utility model is as above, the embodiment that described content just adopts for the ease of understanding the utility model, and be not used to limit the utility model.Technical staff in any the utility model art; under the prerequisite not departing from the spirit and scope disclosed by the utility model; any amendment and change can be done what implement in form and in details; but scope of patent protection of the present utility model, the scope that still must define with appending claims is as the criterion.
