Abstract
The utility model discloses a no bypass sintering flue gas desulfurization flue system. This system still includes the the control unit who is used for controlling main air exhauster including the main air exhauster that is used for extracting the sintering flue gas, the draught fan that the setting entered the mouth at the desulfurizing tower, through the clean flue of confined intercommunication between main air exhauster and the draught fan, the outer wall of clean flue covers there is the heat preservation. The utility model discloses cancel devices such as bypass flue, chimney, bypass damper door, formed the clean flue of no bypass to avoid the sintering flue gas to reveal to the bypass flue, improved desulfurization effect, be favorable to the environmental protection.
Description
Technical field
The utility model relates to flue gas desulfurization purification techniques field, refers to a kind of none-disk terminal sintering flue gas desulfurization chimney system particularly.
Background technology
Be provided with main road flue and bypass flue (as shown in Figure 1) in existing sinter fume exhaust system, wherein, bypass flue is directly connected with chimney, is provided with the by-pass damper door of this flue closed in bypass flue.In the past due to the not supporting corresponding flue gas desulfur device of Some Enterprises, the flue gas that sintering machine produces directly entered air from chimney via bypass flue, and environmental pollution is larger.In recent years in order to respond the call of national environmental protection department, enterprise is supporting sintered flue gas desulfurization device, sinter fume is just discharged in air after entering desulfurizer process via main road flue, and former by-pass damper door is only closed by bypass flue, avoids flue gas directly to drain in air.
But, because by-pass damper gate flap sheet produces burn into wearing and tearing, distortion in long-term production process, make its seal under full off state poor, sinter fume often leaks in chimney discharged to air, thus cause environment protection emission not up to standard, severe contamination is caused to environment.
Summary of the invention
The purpose of this utility model will provide a kind of none-disk terminal sintering flue gas desulfurization chimney system exactly.This system eliminates the devices such as bypass flue, chimney, by-pass damper door, forms unbypassed clean flue, thus avoids sinter fume and leak to bypass flue, improves desulfurized effect, is conducive to environmental protection.
For achieving the above object, none-disk terminal sintering flue gas desulfurization chimney system designed by the utility model, comprising the main exhauster for extracting sinter fume, being arranged on the air-introduced machine of desulfurizing tower entrance, also comprise the control unit for controlling main exhauster, described main exhauster is communicated with by the clean flue closed with between air-introduced machine.
Further, the outer wall of described clean flue is coated with heat-insulation layer, the sinter fume entering clean flue is played to the effect of insulation, thus improves the efficiency of the desulfurization of desulfurizing tower.
Compared with prior art, the utility model tool has the following advantages:
One, the utility model eliminates the devices such as bypass flue, chimney, by-pass damper door, forms unbypassed clean flue, thus avoids sinter fume and leak to bypass flue, improves desulfurized effect, is conducive to environmental protection.
Its two, the outer wall of clean flue of the present utility model is coated with heat-insulation layer, the sinter fume entering clean flue is played to the effect of insulation, thus improves the desulfuration efficiency of desulfurizing tower.
Its three, the utility model structure is simple, saves equipment cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing sintering flue gas desulfurization chimney system;
Fig. 2 is a kind of none-disk terminal sintering flue gas desulfurization chimney system;
Wherein: main exhauster 1, air-introduced machine 2, control unit 3, clean flue 4, main road flue 5, by-pass damper door 6, bypass flue 7, chimney 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
None-disk terminal sintering flue gas desulfurization chimney system as shown in Figure 2, comprise for extracting the main exhauster 1 of sinter fume, being arranged on the air-introduced machine 2 of desulfurizing tower entrance, also comprise the control unit 3 for controlling main exhauster 1, the clean flue 4 by closing between main exhauster 1 with air-introduced machine 2 is communicated with.
In technique scheme, the outer wall of clean flue 4 is coated with heat-insulation layer, the sinter fume entering clean flue is played to the effect of insulation, thus improves the desulfuration efficiency of desulfurizing tower.
When the utility model uses, first close air-introduced machine 2 air door and start air-introduced machine 2, when suitably adjustment air-introduced machine 2 air door makes inlet pressure be about 0, start main exhauster 1, start simultaneously suitably adjustment air-introduced machine 2 throttle opening, by vacuum cavitations at-200 ~ 100Pa until started; During shutdown, first stop main exhauster 1, after progressively close air-introduced machine 2 air door, completely close after stop air-introduced machine 2; When air-introduced machine 2 inlet pressure is greater than 200Pa or is less than-800Pa, report to the police; When air-introduced machine 2 inlet pressure is greater than 1000Pa, main exhauster 1 trips; Main exhauster 1 throttle opening feeds back to desulfurization operations room, and air-introduced machine 2 throttle opening feeds back to main exhauster 1; The inlet pressure data feedback of air-introduced machine 2 is to control unit 3.
The above; be only detailed description of the invention of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
Claims (2)
