Abstract
The invention discloses a system for directly discharging acid liquor in a single-cylinder chimney including high-position gas flue. The problems in a current single-cylinder chimney zero meter drainage organization with a landing gas flue that ashes are easy to jam and a drainage pipeline is difficult to remove the ashes can be solved by the system. The system comprises a high-position gas flue on a single-cylinder chimney wall (1), a manhole door (3) on the zero meter ground of the single-cylinder chimney, a linear drainage channel (4) arranged outside the manhole door (3), an acid liquor settling basin (5) arranged outside the linear drainage channel (4), a box-shaped overflow groove (6) formed in the upper part of the acid liquor settling basin (5), a drainage pipe (7) arranged in the box-shaped overflow groove (6), and a single-way drainage ramp (2) arranged on the zero meter ground in the single-cylinder chimney. The system is clear in function and especially convenient to operate and maintain.
Description
Technical field
The single-drum chimney that the flue high position that the present invention relates to a kind of coal-fired station is arranged, the flue particularly used after an a kind of coal-fired station smoke-gas wet desulfurization high position arranges the acid solution direct discharge system in single-drum chimney.
Background technology
Single-drum chimney is simple with its construction, and short construction period, the feature that cost is low is selected widely.In order to reduce the pollution to environment, coal-burning power plant's wet desulfurizing process is widely adopted, harmful components contained by the flue gas that power plant is discharged are greatly diminished, meanwhile, moisture contained by flue gas can increase greatly, because flue gas is along in single-drum chimney uphill process, flue-gas temperature can decline rapidly, when making flue gas also not discharge single-drum chimney, its temperature is just lower than dew-point temperature, a large amount of condensate water will to be wrapped up in cylinder that dust of mixing flows to single-drum chimney on zero meter face, the condensation sour water of a large amount of low-temperature flue gas from cylinder first along cylinder inwall downstream to zero meter face, condensation water quantity in usual chimney reaches several tons per hour.Chimney zero meter face, as the key position of single-drum chimney dust stratification and draining tissue, carries the discharge task of the inner all acid solutions of chimney.Conventional single-drum chimney zero meter of draining tissue is made up of one-way guide flow ramp, arc-like rows ditch, brick baffle and drainage pipeline four part.Under conventional drainage organization condition, acid solution through barrel downstream to zero meter, chimney, must through one-way guide flow ramp water conservancy diversion, then import in the arc-like rows ditch bottom ramp, and connect by drainage pipeline from arc-like rows ditch and draw, finally discharge chimney.Under such draining tissue, acid solution can not be got rid of outside cylinder in the very first time flowing to zero meter, when cigarette ash comes together in arc-like rows ditch in a large number with acid solution, cigarette ash through precipitation easily causes the bottom discharge line clogging of arc-like rows ditch, in addition drainage pipeline path length, dredging difficulty, will certainly affect draining, makes zero meter of draining organization system there is the hidden danger of paralysis.In order to address this problem, prior art generally adopts two kinds of methods, one arranges bypass flue on single-drum chimney, high-temperature flue gas without wet desulfurizing process is guided in single-drum chimney and the flue gas reducing temperature is heated, this method is polluted because the high-temperature flue gas introduced can not produce air through desulfurization process, is halted by environmental administration.Another kind method is by increasing flue gas equipment, to through wet desulfurizing process but the flue gas also not entering single-drum chimney heat, it is large to there is investment in this method, take the shortcoming that ground space is large, particularly need the occasion making full use of effective stack height and investment reduction cost to realize.
Summary of the invention
The invention provides the acid solution direct discharge system of the single-drum chimney that a kind of flue high position is arranged, solve cigarette ash in single-drum chimney zero meter of draining tissue of existing flue high position layout and easily block the technical problem large with the deashing difficulty of drainage pipeline.
The present invention solves above technical problem by the following technical programs:
The acid solution direct discharge system of the single-drum chimney that an a kind of flue high position is arranged, comprise single-drum chimney barrel, single-drum chimney barrel is provided with high-order flue, zero meter face of single-drum chimney is provided with manhole door, straight line drainage channel is had in the arranged outside of manhole door, acid solution sedimentation basin is had in the arranged outside of straight line drainage channel, the top of acid solution sedimentation basin is provided with box-shaped overflow launder, in box-shaped overflow launder, be provided with drainpipe, zero meter face in single-drum chimney cylinder is provided with single slope drainage ramp.
The gradient in the single slope drainage ramp that zero meter face in single-drum chimney cylinder is arranged is 5%.
Acid solution direct discharge system function of the present invention is distinct, economy and facility, and construction is succinct, and quality easily ensures, facilitates operation maintenance especially.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that A-A in Fig. 1 is to sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
The acid solution direct discharge system of the single-drum chimney that an a kind of flue high position is arranged, comprise single-drum chimney barrel 1, single-drum chimney barrel 1 is provided with high-order flue, zero meter face of single-drum chimney is provided with manhole door 3, straight line drainage channel 4 is had in the arranged outside of manhole door 3, acid solution sedimentation basin 5 is had in the arranged outside of straight line drainage channel 4, the top of acid solution sedimentation basin 5 is provided with box-shaped overflow launder 6, in box-shaped overflow launder 6, be provided with drainpipe 6, zero meter face in single-drum chimney cylinder is provided with single slope drainage ramp 2.
The gradient in the single slope drainage ramp 2 that zero meter face in single-drum chimney cylinder is arranged is 5%.
Along the acid solution of single-drum chimney barrel 1 downstream to zero meter, chimney, by single slope drainage ramp 2 effectively water conservancy diversion, quickly pass through manhole door and flow in the straight line drainage channel of the bottom in one-way guide flow ramp, in the acid solution sedimentation basin of chimney outside.Acid solution is constantly gathered and is started precipitation in acid solution sedimentation basin, make solid descends and liquid floats, when the liquid level in acid solution sedimentation basin reaches box-shaped overflow launder upper edge hole place height, top sour water then natural overflow in box-shaped overflow launder, and connect through the drainage pipeline of box-shaped isopipe root and drain, the mortar of acid solution sedimentation basin middle and lower part then has for clearance.
Implementation step of the present invention is:
The first step, after single-drum chimney and brick baffle foundation construction complete, plain earthen backfill is carried out and compaction in layers to basis;
Second step, carry out zero meter surface construction, and use lime slag sloping, make it form one-way guide flow ramp, the gradient 5%;
3rd step, be initial with one-way guide flow ramp minimum point, form straight line drainage channel with concreting and extend to chimney outside;
4th step, form acid solution sedimentation basin with concreting at chimney outside ground excavation, be connected with straight line drainage channel;
5th step, in acid solution sedimentation basin far-end bight, form the box-shaped overflow launder of cantilever with concreting, the base plate of box-shaped overflow launder exceeds acid solution sedimentation basin base plate 1 meter;
6th step, drainpipe is set in box-shaped overflow launder.
