Description
Technical field
The utility model belongs to a kind of overflow mechanism, particularly a kind of desulfurizing tower spill box of controlling the inner liquid level of desulfurizing tower.
Background technology
For guaranteeing the normal operation of desulfuration efficiency and desulphurization system, in desulfurizing tower, liquid-gas ratio need to be controlled in certain scope, guarantees the basicly stable of doctor solution total amount.
Traditional open single flow overflow launder design, after long-play, can be subject to reaction precipitation thing and pile up impact, when bottom valve blowdown is opened in artificial timing, the one, because discontinuous blowdown causes accumulation, easily fouling, tower body bottom is raised gradually, reduced doctor solution volume space, produce false liquid-gas ratio.The 2nd, liquid level can decline rapidly, has greatly reduced the doctor solution total amount that participates in reaction, does not reach designing requirement, produce disadvantageous running environment, directly cause the low of desulfuration efficiency, the accelerated corrosion of pipeline and equipment, the phenomenon of generation dust stratification, precipitation, obstruction.The 3rd, need artificial fixed cycle operator, produce unsettled operating mode, increase recruitment operating cost.
Utility model content
The purpose of this utility model is to provide a kind of desulfurizing tower spill box, it is rational in infrastructure, easy and simple to handle, under the state that can move continuously in desulphurization system, control accurately the liquid-gas ratio of desulfurization, drain continuously dust/sediment, the liquid level in adjusting tower, meets system long-time steady operation intuitively.
The purpose of this utility model is achieved in that a kind of desulfurizing tower spill box, comprise desulfurizing tower and overflow launder, in the outlet of desulfurizing tower bottom, by pipeline, connecting the import of spill box bottom sidewall, on the bottom surface of spill box opposite side, arranging and exporting, and connecting overflow launder by outlet, before in spill box, on rear wall, be symmetrical arranged respectively two parallel flashboard tracks side by side, on two flashboard tracks, coordinate upper flashboard and lower flashboard are installed respectively, before spill box, the top of rear box wall flashboard guide rail coordinates in the pin-and-hole of uniform setting fastening screw is installed respectively, fastening screw and upper, the both ends of the surface of lower flashboard match, make, lower flashboard location, upper, the upper end of lower flashboard is affixed handle respectively.
The utility model is that the overflow mode of original open straight-line overflow launder is improved to adjustable spill box.Spill box is divided into two parts, and every part becomes independent casing, uses upper and lower two-way double disc to cut off between two parts.Under the flashboard of one of them, edge can regulate casing underclearance size, control of sewage disposal uninterrupted, and the upper edge of another flashboard is controlled the height of liquid level and drains doctor solution spillway discharge.The size of casing and the height of flashboard are determined by the liquid-gas ratio of desulfur technology scheme, lower box blowdown flow and top spillway discharge form operation doctor solution total amount, the gap length that regulates flashboard and bottom half, meets in the situation of liquid level, ensures continuous overflow and produces.During normal work, the cotton-shaped product of desulphurization reaction is drained through the overflow of flashboard top.Dirt ash deposition things under system removing in service etc., are gathered in liquid bottom by Action of Gravity Field, directly through lower box high flow rate blowdown liquid, take away.The upper and lower two-way adjustment of flashboard, can provide different big or small vent flows, coordinates on another flashboard along highly realizing the height of controlling liquid level in tower body simultaneously.After equipment is out of service, a flashboard can be adjusted downwards with lower box and be combined, and the inner doctor solution of sealing tower body, meets working condition requirement while reruning.
Design feature: the utility model spill box is connected with desulfurizing tower bottom by flange pipe, forms casing import, and bottom half is provided with outlet, and box house is provided with twice flashboard, encapsulation process between twice flashboard between import and outlet.Each flashboard can move up and down between flashboard guide rail, uses handle to move flashboard after certain altitude, can fix with bearing pin, departs from after bearing pin, can flashboard be pushed into bottom half by handle.The moving up and down and be fixedly not limited to above-mentioned a kind of mode of flashboard.
The good effect that the utility model produces:
(1) can improve and let out dirty efficiency.Continuous high flow rate blowdown liquid, the inclined design of cooperation tower body bottom, can spray fully and release working reaction sediment and slag dirt.
(2) reduce system operation expense.Spill box can fully be got rid of reactant in the accumulation of tower body bottom, and for system provides liquid-gas ratio more accurately, safeguards system running environment is normally stable, with minimum operating cost, meets maximum desulfuration efficiency.Get rid of the uncertain factor that artificial timing is intervened simultaneously, reduced recruitment cost.
(3) less scaling.This spill box is let out dirt because of free of discontinuities, and continuous liquid flow while normally working, makes under nominal situation less scaling.
(4) handling are safeguarded simple.Simple in structure, be connected with tower body flange pipe, be convenient to care and maintenance.
(5) liquid level in the tower of support control at any time.Liquid level in this spill box reflects liquid level in tower immediately, to need adjust in tower liquid level because of working conditions change time, can adjust easily at any time.
The utility model is rational in infrastructure, easy and simple to handle, has realized under the continuous running status of desulphurization system, accurately drips the liquid-gas ratio of controlling desulfurization, drains continuously dust, sediment, and the liquid level in adjusting tower, meets system long-time steady operation intuitively.
