Description
Technical field
The utility model relates to flue gas desulfurization field, relates in particular to that the flue-gas temperature preventing after wet desulphurization is low, the equipment of " chimney rain ".
Background technology
Spread Wet Flue Gas Desulfurization Technology in steel mill and power plant's industry, in units flue gas desulfurization over half, and adopts wet desulfurizing process at present.Adopt after this technique, after most of technique has been cancelled GGH, the flue-gas temperature after desulfurization is low, and water capacity is high, and the buoyancy of flue gas is less, forms negative pressure in chimney, forms " chimney rain ".
It is larger that the order of severity that chimney breast flue gas drop is carried phenomenon secretly is subject to wet desulfurization system whether to prepare the impact of flue gas heater (GGH) device.The early stage domestic wet desulfurization system putting into operation has been prepared GGH device mostly, but in actual motion, the fouling of GGH, blockage problem are comparatively serious, impact on the whole availability of desulphurization system is also larger, therefore at the recent domestic wet desulfurization system putting into operation, mostly adopt the design without GGH, chimney now becomes " chimney rain ".Cancelled and after GGH, made the saturated wet flue gas of absorption tower outlet directly enter chimney, along with the reduction of the flue-gas temperature drop that more easily freeze-outs.
In flue gas, drop is taken in atmospheric environment at chimney breast, and the large drop that some of them have little time diffusion, evaporation will drop to chimney surrounding ground, and this phenomenon is called as " chimney rains " or " acid mist sedimentation ".In " chimney rain " phenomenon, drop in the drop on ground and contain certain impurity, mainly comprise a small amount of SO
2, SO
3and gypsum slurries, dust etc.SO
2, SO
3react the sulfuric acid forming sulfurous acid alive with water, make drop be acid, the building of periphery, vehicle lacquer painting are had to certain pollution, detrimental effect; The drop that contains gypsum slurries, dust drops down onto ground, also can make the sanitary conditions of chimney neighboring area worsen.
Steel mill and power plant have some discarded hot flue gases substantially, temperature is more than 100 ℃, can realize twice laid, utilizing hot flue gas to mix with wet flue gas after desulfurization can be by the temperature increase of wet flue gas, after temperature increase, increase the pull out force of chimney, the increase of drop pull out force, the diffusion area of discharging chimney are increased, thereby solve the problem of " chimney rains ".
Summary of the invention
For solving the problem and blemish of above-mentioned middle existence, the utility model provides wet flue gas heat riser after a kind of wet process of FGD, this device, having guaranteed on the desulphurization system in early stage, without any impact, also to make the temperature of desulfurization wet flue gas raise, has prevented the formation of " chimney rain " simultaneously.
Described technical scheme is as follows:
After a kind of wet process of FGD, wet flue gas heat riser comprises: comprise the mixed of thermal source flue, thermal source flue gas and desulfurization fume
Locking device, air-introduced machine and instrument control device, described device specifically comprises by-pass damper door (2), flue collector baffle door (3), mixer entrance baffle door (4), flue gas blender (5), desulfuration chimney (6), desulfurizer (7), sintering machine (8), sinter machine discharge end dedusting device (9), sinter machine discharge end dedusting chimney (10);
Described air-introduced machine is connected with described sinter machine discharge end dedusting device with described by-pass damper door respectively;
Described flue collector baffle door is connected with described mixer entrance baffle door, and mixer entrance baffle door is also connected with described flue gas blender;
Described flue gas blender is connected with desulfurizer with described desulfuration chimney respectively.
The beneficial effect of the technical scheme that the utility model provides is:
In the situation that guaranteeing not consume in factory resource, utilize discarded hot flue gas to make desulfurization wet flue gas temperature increase, realized twice laid, the formation that has also solved " chimney rain ", makes to discharge desulfurization wet flue gas diffusivity and increases simultaneously.
Accompanying drawing explanation
Fig. 1 is to wet flue gas heat riser structural representation after wet process of FGD.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:
As shown in Figure 1, shown wet-method desulfurized fume heat riser structure, mixing arrangement, air-introduced machine and the instrument control device of thermal source flue, hot flue gas and desulfurization fume, the air-introduced machine 1, by-pass damper door 2, flue collector baffle door 3, mixer entrance baffle door 4, flue gas blender 5, desulfuration chimney 6, desulfurizer 7, sintering machine 8, sinter machine discharge end dedusting device 9, the sinter machine discharge end dedusting chimney 10 that specifically comprise transformation, described air-introduced machine is connected with described sinter machine discharge end dedusting device with described by-pass damper door respectively;
Described flue collector baffle door is connected with described mixer entrance baffle door, and mixer entrance baffle door is also connected with described flue gas blender;
Described flue gas blender is connected with desulfurizer with described desulfuration chimney respectively.
Above-mentioned sintering machine is connected with described sinter machine discharge end dedusting device.
The flue of hot flue gas utilizes air-introduced machine that hot flue gas is delivered in the low temperature flue after desulfurization, and thermometric and pressure measurement instrument are set before flue gas blender, and temperature measuring device is set after blender.
In said apparatus, original hot flue gas enters sinter machine discharge end dedusting chimney 10 after by air-introduced machine 1 and discharges by deduster dedusting, in order to realize twice laid, by after 1 transformation of the original air-introduced machine of hot flue gas, increase resistance that pressure overcomes post facility and the flue wet flue gas after to desulfurization and heat up.
In said apparatus, by-pass damper door 2 is closed, flue collector baffle door 3 makes thermal source flue gas utilization air-introduced machine 1 to be passed in flue gas blender 5 after opening.
In said apparatus, the wet flue gas temperature of desulfurization is at 60 ℃, temperature is low, the diffusivity that causes flue gas to be discharged after chimney is less than normal, form " chimney rain ", in order to improve the generation of this situation, after desulfurizer 7 and before desulfuration chimney 6, flue gas blender 5 is set, after hot flue gas is fully mixed with desulfurization wet flue gas, through desulfuration chimney 6, discharge.After wet flue gas temperature after desulfurization is raise, the pull out force that makes flue gas discharge chimney increases, and flue gas diffusion effect is good.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
