Abstract
The utility model discloses pulp stirring equipment of a desulfurizing tower. The pulp stirring equipment comprises a jet nozzle positioned in the desulfurizing tower and an impulse suspending pump positioned outside the desulfurizing tower, wherein the jet nozzle is connected with the impulse suspending pump through a pipeline, the impulse suspending pump is connected with a desulfurizing tower pulp pool, and the orifice of the jet nozzle is toward the bottom of the desulfurizing tower. The pulp stirring equipment disclosed by the utility model has the advantage that the impulse suspending pump which is arranged outside the tower can be overhauled without stopping the desulfurizing system even having a fault, so that the phenomena of precipitation and scaling can be prevented, and therefore, the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of boiler flue gas desulfurization equipment, and specifically a kind of desulfurizing tower stock tank mixing plant, belong to the boiler flue gas desulfurization apparatus field.
Background technology
Present desulfuration field mainly adopts hollow-spraying-tower to carry out flue gas desulfurization, the doctor solution endless form adopts circulation in tower, stock tank is set bottom desulfurizing tower, precipitate at tower bottom for fear of doctor solution, need to prevent contamination precipitation at the inner installation side feeding mixer of tower body, yet there are the problems such as machine leak sealing water, mixing arm easily are corroded in side-feeding mixer in application process, only have inactive desulphurization system to overhaul it when the problems referred to above occurring, affect normal production work, reduced production efficiency.
The utility model content
In order to address the above problem, the utility model has designed a kind of desulfurizing tower stock tank mixing plant, and the pulse suspension pump is arranged on outside tower, even the desulphurization system of also need not stopping using when problem appears in the pulse suspension pump just can be overhauled, prevent precipitation and scale formation, improved production efficiency.
The technical solution of the utility model is:
A kind of desulfurizing tower stock tank mixing plant, described mixing plant comprises the nozzle that is positioned at desulfurizing tower and is positioned at the outer pulse suspension pump of desulfurizing tower, described nozzle is connected by pipeline with the pulse suspension pump, described pulse suspension pump is connected with the desulfurizing tower slurry pool, and the spout of described nozzle is at the bottom of the tower of described desulfurizing tower.
Further, described pulse suspension pump is anticorrosive anti-wear slag stock pump.
Further, the described pipeline that is positioned at the desulfurizing tower part is GRP pipe.
The utility model is equipped with the nozzle at the bottom of tower in desulfurizing tower, by the pulse suspension pump, liquid is extracted out from desulfurizing tower slurry pool top during startup, in slurry pipe line is returned the cyclic oxidation pond again, when spraying, slurries can produce pulse from nozzle, rely on the solid content at the bottom of tower has been stirred in this impulse action, and then prevent precipitation.When normal operation, enable the slurries lower inlet, increase the kinetic energy of nozzle pulse, to strengthen the mixed effect of slurries and oxidation air, improve the effect of desulfurization resultant, prevent that fouling from occuring.
The utility model stirs to compare with existing employing agitator has following features:
(1) there is no mechanical agitator or other rotatable parts in absorption tower recycle slurry liquid pool, fault is low;
(2) stirring is more even than side-feeding mixer, can not produce precipitation at the bottom of tower;
(3) need not operation during desulfurizer is stopped transport, save energy.When again putting into operation, can suspend fast by dedicated line.When desulfurization resultant does not utilize, but the gap operation of suspension pulser, power saving;
(4) availability and the processing safety of desulfurizer have been improved.Levitated pump is arranged on outside tower, has solved the maintenance trouble of side-feeding mixer shaft seal seepage.Can change or maintenance pulse suspension pump at the absorption tower normal operation period, need not to interrupt sweetening process or emptying absorption tower;
(5) add the fresh lime white in the recycle slurry liquid pool can obtain mixing continuously and uniformly, utilization rate is improved, and then is conducive to reduce calcium sulfur ratio;
(6) its design and layout are considered the best distribution of oxidation air and the abundant oxidation of slurries, and oxidation efficiency is higher than conventional side-feeding mixer;
(7) in the pulse suspension system tower, part only has shower nozzle and cleaning hose, have to resistance to wear and anti-obstruction design, and can clearance-type work.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment desulfurizing tower stock tank mixing plant;
Fig. 2 is the top view of Fig. 1;
In figure: 1-pulse suspension pump, 2-pipeline, 3-nozzle.
The specific embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, a kind of desulfurizing tower stock tank mixing plant, comprise the nozzle 3 that is positioned at desulfurizing tower and be positioned at the outer pulse suspension pump 1 of desulfurizing tower, nozzle 3 is connected by pipeline 2 with pulse suspension pump 1, pulse suspension pump 1 is connected with the desulfurizing tower slurry pool, and the spout of nozzle 2 is at the bottom of the tower of described desulfurizing tower.
The concrete size of pulse suspension pump and pipe diameter is decided according to actual condition, and this routine described pipe diameter distance is 100mm, and at the bottom of the jet opening distance tower, distance b is 800mm, and pulse suspension pump sulfur content is 100m
3/ h.
The pulse suspension system water pump adopts anticorrosive anti-wear slag stock pump, and the tower interior conduit adopts GRP pipe.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.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.
