Technical Field
The utility model relates to a desulfurizing tower technical field specifically is semi-dry desulfurization tower entry helps blows system.
Background
In the semi-dry desulfurization tower without the blowing-assisting system, because the resistance of a concave part at the inlet of the absorption tower is larger, part of dust in the flue gas from the boiler can be accumulated when the flue gas passes through the concave part, if the ash can not be removed in time, more and more dust is accumulated to block the flue at the inlet of the absorption tower, and in case of serious conditions, the induced draft fan is stopped, and the boiler is flamed out. In order to compensate the defects, resistance is reduced by means of lengthening the length of a flue at the entrance of the concave part and the like, so that material loss is high, and the occupied area is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a semidry process desulfurizing tower entry helps blows system to propose the flue for the spill in solving above-mentioned background art, the flue gas resistance is great, the problem of the ash that easily falls.
In order to achieve the above object, the utility model provides a following technical scheme: the inlet blowing-assisting system for the semi-dry desulfurization tower comprises a desulfurization tower main body and a longitudinal blowing-assisting pipeline, wherein an inner wall plate is arranged below the desulfurization tower main body, a transverse blowing-assisting pipeline is arranged below the inner wall plate, and the longitudinal blowing-assisting pipeline is positioned in the middle of the rear end of the transverse blowing-assisting pipeline.
Preferably, the transverse blowing-assisting pipelines are uniformly distributed along the central axis direction of the longitudinal blowing-assisting pipeline, the distance between the transverse blowing-assisting pipelines is 350mm, and three groups of three transverse blowing-assisting pipelines are arranged.
Preferably, the outer part of the transverse blowing-assisting pipeline is of an n-shaped structure, and the depth of the transverse blowing-assisting pipeline penetrating through the desulfurizing tower main body is 30 mm.
Preferably, the transverse blowing-assisted pipeline and the longitudinal blowing-assisted pipeline are both made of carbon steel, the diameter of the inner wall of the transverse blowing-assisted pipeline is 10mm, and the width diameter of the inner wall of the longitudinal blowing-assisted pipeline is 20 mm.
Preferably, the longitudinal blowing-assisting pipelines are uniformly distributed along the bottom surface wall of the inner wall plate, the distance between every two adjacent longitudinal blowing-assisting pipelines is 600mm, the number of the longitudinal blowing-assisting pipelines is four, and the longitudinal blowing-assisting pipelines are parallel to each other.
Compared with the prior art, the beneficial effects of the utility model are as follows: blowing dust in flue gas at an inlet flue of the absorption tower into the absorption tower; reducing the dust accumulation of the inlet flue; the invention avoids the occurrence of the conditions of flue blockage, the jump stop of an induced draft fan, the flameout of a boiler and the like, and can mainly blow the dust in the flue gas at the inlet of the absorption tower into the absorption tower so as to reduce the dust accumulation of the inlet flue;
1. after the auxiliary blowing system is added, the utility model is equivalent to strengthening the air flow, so that the deposited dust falling at the inlet is added into the flue gas system again and enters the absorption tower, thereby effectively avoiding the dust falling at the inlet of the absorption tower, enabling the system to run more stably and avoiding worrying about the blockage of the inlet flue;
2. the utility model discloses after the setting helped the blowing device, can effectively avoid the formation to the deposition. The blowing assisting device is made of carbon steel, is low in price, saves cost compared with a lengthened flue, saves space, is safe and reliable, blows the accumulated dust into the absorption tower through blowing assisting if the accumulated dust is accumulated, and does not influence the stability and normal operation of the system by adding the smoke system again.
