Abstract
The invention relates to a self-cleaning type overflow dam device. Liquid supply nozzles having agitating functions are uniformly arranged at multiple points in an overflow dam groove so as to carry out sufficient agitation, prevent the solid phase substances of liquid from settling, solve possible sludge deposit problems, avoid overflow dam failure and keep stable overflow dam operating for a long term. An overflow opening of the overflow dam is provided with a triangular groove-shaped opening, and a wave calming plate is arranged below the triangular groove-shaped opening of the overflow opening, so that the adverse effect of the water level variation of the overflow dam on overflow distribution is reduced, and the effect of liquid fluctuation on overflow stability is reduced. The wave calming plate is used for stabilizing the wave amplitude of liquid, and improving liquid supply stability. The self-cleaning type overflow dam device can obviously improve the work reliability of the overflow dam, prevent sand from settling in the overflow dam groove, and solve overflow dam failure problems resulting from sand accumulation. The self-cleaning type overflow dam device is mainly used for protecting an inverse spray pipe of a vertical pipe type scrubber, and can be used for protecting other similar equipment requiring the protection of the overflow dam.
Description
Technical field
The present invention relates to a kind of weir arrangement, relate in particular to a kind of weir arrangement of dynamic wave scrubber reverse jet tube.
Background technology
Dynamic wave scrubber is external a kind of industrial flue gas cleaning washing facility.Its operation principle is by the cleaning solution Thysanophyllum that forms in reverse jet tube, washs the industrial smoke of adverse current from top to bottom.By the abundant contact of gas-liquid, gas-solid phase and collision at a high speed, reach the purpose of cooling dedusting.In recent ten years, by equipment and technology that digestion is introduced, dynamic wave scrubber has obtained increasing application at home.Adopted weir arrangement in the dynamic wave scrubber, be mainly used in and prevent the infringement of high-temperature flue gas, also can prevent the reverse jet tube encrustation the reverse jet tube wall.External dynamic wave scrubber adopts high alloy to make reverse jet tube more, the reliability height, and cost is also high.Use the macromolecule nonmetallic materials to substitute when domestic digestion is used, reduced equipment manufacturing cost (only reach high alloy material make 1/tens) significantly.Simultaneously, the side effect of doing like this is the operation risk that has increased equipment.Domestic some reverse jet tubes took place burnt out accident.Cause the reason of accident to have two: one, because the downflow weir employing is the cycles of washing liquid that contains certain solid formation, solid formation deposits in the overflow weir notch, causes the cutout of part spillwag chute, causes the reverse jet tube part to burn out.After through improving, at the downflow weir trench bottom end-of-the-pipe is set, take to be interrupted or the way of continuous blowdown, still can not fine solution blockage problem; The 2nd, its simple relatively downflow weir structure, when the weir level degree changed, it is serious that feeding is unbalance, also causes local macromolecular material to be burnt out.Above-mentioned is exactly principal risk and the problem that domesticizes and exist when dynamic wave scrubber is used.
Summary of the invention
The object of the present invention is to provide a kind of self-cleaning weir arrangement, overcome when former weir arrangement is used muddy cycles of washing liquid as overflowing liquid and cause downflow weir to stop up the problem that causes the reverse jet tube part to burn out.
A kind of self-cleaning weir arrangement, it is characterized in that: employing multiple spot in the overflow weir notch evenly is provided with the method for band agitating function nozzle feed flow, when being implemented in feed flow liquid is fully stirred, avoid solid formation in the overflow weir notch, to deposit, keep the long-term stability operation of downflow weir.
The technical measures supporting with this invention comprise: because stirring action causes the influence of liquid level undue fluctuation to the overflow stationarity, flat ripple plate to be set below overfall in order reducing, to be used for the wave amplitude of stable liquid, improve the stable and harmonious of feed flow.
Adapt to the ability that its levelness changes for improving downflow weir simultaneously, on spillwag chute, offer leg-of-mutton flute profile overfall, in the time of can relaxing the weir level degree and change overflow is distributed uneven influence.
The invention has the advantages that: the feed liquid method that has adopted inner carrying liqs to stir, the sludgd deposition problem that elimination may exist is avoided the inefficacy of downflow weir.Adopted the auxiliary overflow mode of triangle open mouth to divide into horizontalization ripple plate at spillwag chute, can effectively improve the stationarity and the harmony of downflow weir feed flow with it.Take these methods and measure, can improve the reliability of downflow weir at all, thereby solve the subject matter that the production domesticization dynamic wave scrubber runs into.
Simultaneously, these measures and method also have general significance, can be applied on the similar device and equipment that needs overflow protection.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 plan structure schematic diagram.
The specific embodiment
Describe embodiments of the present invention in detail below in conjunction with accompanying drawing:
Self-cleaning weir arrangement of the present invention, level evenly is provided with some feed liquor mouths of pipe in overflow weir notch 4, the feed flow nozzle 3 of mounting strap agitating function on the mouth of pipe.The nozzle of band agitating function can be in market purchasing, also can be according to liquid supply rate etc. require the specialized designs manufacturing.On spillwag chute, offer jagged triangle overfall 1.Because the triangle overfall top of offering may expose at high temperature, can make the overfall pipe nipple with special material (as high purity graphite, Hastelloy etc.).Overfall pipe nipple lower end has many dihedral level troughs, is convenient to spread the situation that the end overflow of homogenizing triangle overfall point is concentrated.Below overflow plane triangle opening, wing horizontal ripple plate 2 is set.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention; make some alternative or obvious modification that are equal to without departing from the inventive concept of the premise; and performance or purposes are identical, then should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
Claims (3)
1. self-cleaning weir arrangement is characterized in that: adopt in overflow weir notch multiple spot that the method for band agitating function nozzle feed flow evenly is set, when being implemented in feed flow liquid is fully stirred.
2. self-cleaning weir arrangement according to claim 1 is characterized in that: flat ripple plate is set below overfall, is used for the wave amplitude of stable liquid, improve the stable and harmonious of feed flow.
