Abstract
The utility model provides a dry desulphurization flue gas humidity regulating device which can ensure the temperature and humidity of flue gas of a boiler and cause absorbent to have good activity and further increase the desulfuration efficiency of an absorption tower. The dry desulphurization flue gas humidity regulating device adopts the technical scheme that the device comprises an absorption tower, a boiler gas flue , and a process water injection device; an outlet of the boiler gas flue is communicated with the bottom of the absorption tower; the process water injection device is arranged in the interior of the absorption tower; the top of the absorption tower is a flue gas outlet; the device is characterized in that the interior of the boiler gas flue is provided with a perforated steam pipeline; an inlet of the perforated steam pipeline is communicated with an external lower pressure saturated steam supply device.
Description
Technical field
The utility model relates to the dry desulfurization mechanical device apparatus field of boiler smoke, is specially a kind of dry desulfurization smoke moisture adjusting device.
Background technology
Existing dry desulfurization device, its bottom on the absorption tower feeds the boiler smoke that needs desulfurization, the jetting device of fresh water (FW) is housed in the inside on absorption tower, but because the boiler flue gas outlet temperature is on the low side, even spraying into of fresh water (FW) arranged, the humidity of flue gas is on the low side, causes the active not good enough of absorbent, the flue gas desulfurization effect is not up to standard, and the desulfuration efficiency on depickling absorption tower is low.
Summary of the invention
At the problems referred to above, the utility model provides a kind of dry desulfurization smoke moisture adjusting device, and the temperature and humidity that it can guarantee boiler smoke makes the active good of absorbent, and then the desulfuration efficiency on absorption tower is improved.
A kind of dry desulfurization smoke moisture adjusting device, its technical scheme is such: it comprises absorption tower, boiler smoke flue, fresh water (FW) jetting device, the outlet of described boiler smoke flue is communicated with the bottom on described absorption tower, described fresh water (FW) jetting device is arranged in inside, described absorption tower, the top on described absorption tower is an exhanst gas outlet, it is characterized in that: described boiler smoke channel interior is equipped with the jet chimney of perforate, and the inlet of the jet chimney of described perforate is communicated with outside low-pressure saturated steam feedway.
It is further characterized in that: the jet chimney of described perforate is specially porous uperize pipeline, and the injection direction of described porous uperize pipeline is parallel to flow of flue gas direction in the described boiler smoke flue;
The low-pressure saturated steam feedway specifically comprises service, valve, low-pressure saturated steam source, described low-pressure saturated steam source is the low-pressure saturated steam of steam power plant, the low-pressure saturated steam of described steam power plant connects the inlet of described porous uperize pipeline by described service, and described service is equipped with valve.
After adopting structure of the present utility model, before boiler smoke enters into the absorption tower, low-pressure saturated steam is imported low-pressure steam by the jet chimney of perforate in the boiler smoke passage, boiler smoke has not only improved temperature, and improved humidity, and after entering in the absorption tower, passes through the boiler smoke that has improved temperature and humidity the humidification of fresh water (FW) again, make the active good of absorbent, the flue gas of output is up to standard, and the desulfuration efficiency on absorption tower is improved.
Description of drawings
Fig. 1 is a front view structural representation sketch of the present utility model;
Fig. 2 is the broken section enlarged drawing of boiler smoke flue of the present utility model.
The specific embodiment
See Fig. 1, Fig. 2, it comprises absorption tower 1, boiler smoke flue 2, fresh water (FW) jetting device 3, the outlet of boiler smoke flue 2 is communicated with the bottom on absorption tower 1, fresh water (FW) jetting device 3 is arranged in 1 inside, absorption tower, the top on absorption tower 1 is an exhanst gas outlet 4, porous uperize pipeline 5 is equipped with in boiler smoke passage 2 inside, the injection direction of porous uperize pipeline 5 is parallel to flow of flue gas direction in the boiler smoke flue 2, the inlet of porous uperize pipeline 5 is by the low-pressure saturated steam 7 of outside service 6 connection steam power plants, and service 6 is equipped with valve 8.The direction of arrow is the boiler smoke flow direction among Fig. 1, and the direction of arrow is boiler smoke flow direction or low-pressure saturated steam injection direction among Fig. 2.
Its operation principle is as follows: by the quantity delivered of valve 8 control low-pressure saturated steams, regulate the temperature and humidity of the boiler smoke in the boiler smoke flue 2, and then the temperature and humidity of guaranteeing to enter into the boiler smoke in the absorption tower 1 is the active good state of absorbent.
