Description
Technical field
The utility model relates to a kind of environmental protection equipment, is specially a kind of lime conveying device that is applicable to flue gas desulfurization.
Background technology
Mainly be to be that raw material carries out flue gas desulfurization to fume desulphurization method at present, through the alkali lye preparation with carry, carry out desulphurization reaction then with lime or other alkali sources.It is simple in structure in the domestic existing equipment lime (other alkaline metal oxides) being carried main existing problems, and equipment is single, and operating automation degree is low, and labor intensity of operating staff is big, the with serious pollution problem of site environment.
Summary of the invention
The utility model is low in order to solve in the flue gas desulfurization lime course of conveying that exists in the prior art operating automation degree, problem such as labor intensity of operating staff is big, and site environment is seriously polluted, and a kind of lime conveying device that is applicable to flue gas desulfurization is provided.
The utility model is realized by following technical scheme, a kind of lime conveying device that is applicable to flue gas desulfurization, comprise the lime feed bin, establish sack cleaner at lime feed bin top, discharging opening place, lime feed bin bottom is provided with star-like dispenser, lime feed bin bottom discharging opening is connected with conveying worm, and the below of conveying worm upper end is provided with gravimetric tank, and the gravimetric tank below is provided with the ashing jar.
Compared with prior art, the utility model: 1. establish sack cleaner, sack cleaner filtration velocity on the lime silo top: regularly sack cleaner is carried out blowback.So not only can reduce pollution, can also reduce the waste of lime environment.2. star-like charging gear is adopted in the discharging of lime silo bottom, and adopts variable-frequency motor evenly to control the lime conveying capacity.3, under the star-like charging gear vertical screw type conveyer is set, vertical screw type conveyer spiral assembly and axle head adopt spline to connect, and mounting or dismounting are convenient, and bearing capacity is big, and is good to neutrality, safe and reliable.Vertical screw type conveyer also has good airproof performance, and volume is little, and rotating speed height, varying pitch are guaranteed the characteristics of evenly carrying fast.4. be transported to gravimetric tank after the conveying worm outlet is made certain angle of inclination according to field condition.5, in the gravimetric tank bottom electric pushrod device for discharging is set.Can realize that the teletransmission of electric pushrod device controls automatically.When the LOAD CELLS of gravimetric tank was shown to setting value, electric pushrod was opened automatically, the automatic discharging of gravimetric tank.
In a word, described in the utility modelly be applicable to that the lime conveying device of flue gas desulfurization is reasonable in design, compact conformation, the automaticity height, the transfer efficiency height does not have dust to rush down outward, environmental protection.
