Abstract
The utility model provides an ash-fishing facility with double settling ponds of a fire coal flue gas desulphurization system. The facility comprises two settling ponds which are adjacently arranged, wherein one of the settling ponds is used while the other end is for later use. An acid-base mixing pond located in the upriver of each settling pond is built on one side of each settling pond, and each acid-base mixing pond is communicated with an acidic water slagging conveying pipeline and an alkaline water conveying pipeline. Each settling pond is internally provided with a submersible wall which is lower than the wall of the settling pond relative to one side of the acid-base mixing pond. A water return channel is formed on one side of each submersible wall, separated from the acid-base mixing pond. The two water return channels are communicated with a water collecting well 1. As the facility provided by the utility model is provided with two settling ponds, one of the settling ponds is used while the other end is for later use, and the two settling ponds alternately work. The facility not only solves the problem that plaster which is too thin is hard to fish out, but also further avoids halt of combustion equipment, thereby guaranteeing continuous production.
Description
Technical field
The utility model relates to a kind of settling tank structure, the settling tank structure that particularly coal-fired flue gas desulfurization system is used.
Background technology
Current coal-fired flue gas desulfurization system, general design technology is for to make the modes such as the materials such as the sulfurous gas in flue gas wash with water its disengaging and to collect in settling tank, in settling tank, drop into again the alkaline matters such as unslaked lime, by after the water liquid acid-base neutralisation in settling tank, reactant precipitation, clear water is back in sprinkling system and recycles again.
Yet, settling tank is after being used for some time, the materials such as sulfurous gas react the plaster producing and can build up in settling tank bottom more and more higher with liming chemistry, if plaster can not be cleared up (dragging for ash) in time, settling tank is by ineffective, and whole desulphurization system also cannot normally be moved.
At present, a settling tank is all set, when in settling tank, throw out runs up to a certain degree, employing is dragged for ash grab bucket and directly from settling tank, plaster is pulled out.Yet, the described plaster thing that not hardens, in dragging for grey process can with the clear water generation mixed flow on settling tank upper strata, make whole settling tank a slice muddy, not only actual to drag for grey efficiency extremely low, and force the combustion equipment must break-off.

Because the track 32 of transfer gantry grab bucket 30 is positioned at the outside of a described pump well 16, its ground affects an outside draining of pump well 16, for this reason, No. two pump wells 17 of track 32 arranged outside in described transfer gantry grab bucket 30, described No. two pump wells 17 are connected by communicating pipe 18 with a described pump well 16, No. two pump well 17 upper end hole-openings form the mouth of a river 171, make water pass through this hole and flow into the recycle system, for described coal-fired flue gas desulfurization systemic circulation, use.
Use the utility model, can guarantee to drag for grey effect, and needn't suspend combustion equipment, its use procedure is as follows:
As shown in Figure 1, suppose that the settling tank 10 that is arranged in Tu Zhong right side accumulated abundant plaster, the soda acid mixing pit 20 on Ze Tuzhong right side is stopped using, make the settling tank 10 that is arranged in figure left side in use state simultaneously, acidic aqueous liquid is with after alkaline milk of lime mixes in corresponding soda acid mixing pit 20, as shown in the direction of arrow in figure, flow through backwater road 13, water leg 15, pump well 16 and No. two pump wells 17, the water outlet 171 by No. two pump well 17 upper ends flow into the recirculation of coal-fired flue gas desulfurization system and uses;
Meanwhile, described transfer gantry grab bucket 30 starts to enable, first a water pump is hung to the clear water degree of depth in right side settling tank 10, the clear water of surface location in right side settling tank 10 is drawn in the settling tank 10 of left side, by the time, after clear water extracts substantially, can start described transfer gantry grab bucket 30 and drag for ash; Certainly, if the inadequate thickness still of the plaster in right side settling tank 10 now, can also harden with the plaster that truck is thrown in settling tank 10 in the lime-ash ，Shi right side settling tank 10 of dry combustion equipment sintering to the right, can make the grey efficiency of dragging for of transfer gantry grab bucket 30 further improve.
Owing to the utlity model has two settling tanks 10, these two settling tank 10 the using and the reserved, alternation, drags for ash thoroughly, has not only improved and has dragged for grey efficiency, also avoids combustion equipment to shut down, and makes to produce and carries out continuously.
Shown in Fig. 3, the utility model also can provide another kind of embodiment, that two settling tanks 10 are set up in parallel, described in each, one side of settling tank 10 has a soda acid mixing pit 20 that is positioned at described settling tank 10 upstreams, and described in each, soda acid mixing pit 20 is communicated with sour water deslagging transport pipe and alkaline water transport pipe;
Described in each, in settling tank 10, with respect to one side of described soda acid mixing pit 20, be provided with one height lower than the unrestrained waterwall 12 of settling tank 10 bodies of wall, each stifled described unrestrained waterwall 12 forms a backwater road 13 away from a side of described soda acid mixing pit 20, article two, described backwater road 13, every backwater Dao13 one end has Yi Geguo water hole 14, two described water holes 14 of crossing are all connected with a water leg 15 upstream, and described water leg 15 downstream is communicated to pump well 16 No. one;
The same transfer gantry that is provided with above described two settling tanks 10 grabs bucket 30, one side of a described settling tank 10 has a potass pool 31 therein, at No. two pump wells 17 of track 32 arranged outside of described transfer gantry, described No. two pump wells 17 are connected by communicating pipe 18 with a described pump well 16.
Adopt this kind of structure, can realize goal of the invention of the present utility model equally.
More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skills understand, in the situation that do not depart from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all falling into protection domain of the present utility model.
