Abstract
The utility model relates to a semi-pipe type ridge demisting liquid-receiving rectifying device, consisting of a shell, demisters, drainage plates, drainage pipe orifices, supporting beams and supporting risers, wherein each demister adopts a ridge structure which is formed by two layers of semi-pipes in a stagger manner, is supported by supporting beams, and is positioned between an upper spraying layer and a lower spraying layer; and slurry sprayed by the upper spraying layer or washing water falls on the semi-pipe type ridge demister, and the slurry flows into a slurry channel consisting of the drainage plates and a demister supporting risers or a tower wall along the inner wall of a semi-pipe and then flows out of a tower through the drainage pipe orifices. The semi-pipe type ridge demisting liquid-receiving rectifying device can be applied to a dual-cycle wet process sulfur system and an ammonia process desulfurization device with a flushing device, and has the advantages of being easy to implement and saving the investment.
Description
One, technical field
The utility model belongs to industrial waste gas purifying environmental protection and energy field, and the demist of particularly a kind of semi-canal type ridge connects the liquid fairing.
Two, background technology
Wet desulfurizing process is that current China uses at most, the most effective fume desulphurization method, and the design desulfuration efficiency is not less than 95%.But power plant produces with coal and can only determine that the coal sulfur content significantly increases according to the market supply situation at present, makes burning coal and design ature of coal have bigger difference; Simultaneously, also there is increase to a certain degree in the boiler smoke amount, causes some desulfurizer can not reach original design desulfuration efficiency, SO
2Can not qualified discharge; Moreover " thermal power plant's atmosphere pollutants emission standards " that Environmental Protection Department and national quality supervision and inspection epidemic disease general bureau unite issue on July 29th, 2011 (GB13223-2011) carried out stricter requirement to various Air Pollutant Emission limit values.
For adapting to the variation of above-mentioned objective condition, guarantee desulfurizer safety, efficient, stable operation, and satisfy environmental protection and newly mark requirement, must carry out extending capacity reformation to existing desulfurizer.
It is that a kind of change amount is less, obvious results extending capacity reformation method that desulphurization system is transformed into the two circulation wet desulfurizing process systems of height pH value.
It is as follows that the two circulation wet desulfurizing process System Expansion of height pH value are transformed main points:
It is constant to keep the following structure of absorption tower spraying layer, and as the tower prime cement liquid pool one-level circulatory system, its slurry pH value generally is controlled at 4～5; In addition, increase the outer slurries case secondary circulatory system of tower, install spraying layer at the tower body top additional and connect liquid device, in the slurries case, its slurry pH value generally is controlled at 5.5～6.5 to the slurry reflux of collection outside tower; In same absorption tower, realized the two-stage circulatory system of the two pH value controls of slurries like this.Boiler smoke passes and connects the further purification of secondary loop slurry spray district that liquid device enters tower body top after departmental level loop slurry spray is distinguished purification under the absorption tower, and process two-stage loop slurry spray washing is to guarantee SO in the flue gas
2Qualified discharge.
In the ammonia desulfurizing process, it is this technology of puzzlement and a subject matter that restricts this process application that " the escaping of ammonia " and ammonium salt carry.The water flushing can effectively reduce amount of ammonia slip and the ammonium salt amount of carrying.The flue gas flusher will be located at the top of spraying layer, and flusher need be in normal fortune state, can not intermittently carry out.If but the flue gas flusher is set in ammonia process of desulfurization tower, flushing water is directly fallen in the circulation stock tank, will destroy the water balance in the tower, therefore needs a kind of connecing to cause outside the tower after liquid device is collected flushing water.
Three, utility model content
The purpose of this utility model is at the problem that exists in the wet desulfurization system, provides the demist of a kind of semi-canal type ridge to connect the liquid fairing.
The utility model device is realized in the following way: the demist of a kind of semi-canal type ridge connects the liquid fairing, constitute by housing demister, drain bar, the draining mouth of pipe, brace summer, support mainboard, the ridge type structure that described demister is made up of the two-layer semicanal that staggers constitutes, gapped between the semicanal, lower floor's semicanal is symmetrical in the position in semicanal gap, upper strata, the limit wall of upper strata semicanal and lower floor's semicanal has coincidence slightly, demister is between last spraying layer and following spraying layer, the demister both sides are provided with supporting vertical plate, and demister bottom is supported by brace summer.Semicanal is a semicircular structure, also can adopt en shape structure.Be equipped with one deck drain bar on the brace summer, also be covered with drain bar between demister supported on both sides riser and tower wall, the end of drain bar is provided with the draining mouth of pipe.
The utility model device is arranged between top spraying layer (spraying layer of the one-level circulatory system or the spraying layer of flushing water) and the bottom spraying layer (spraying layer of the secondary circulatory system or ammonia process of desulfurization spraying layer).Demister is made up of two-layer semicircular pipe that staggers or half rectangular tube, and the registration that the Bian Biyou of two-layer semicanal is certain can almost all be collected to guarantee the slurries under the spraying layer spray of top.Simultaneously, when flue gas passed demister, demister had carried out further rectification to flue gas, so that flue gas has better mass transfer effect when slurries under the top spraying layer spray contact.
The utility model can be used for two circulation wet desulfurization systems, and the ammonia method desulfurizing system of band flusher, has advantages such as easy enforcement, reduced investment.
Four, description of drawings
Fig. 1 is the cross-sectional view of this device in the absorption tower,
Fig. 2 is the structure schematic top plan view of this device,
Fig. 3 is that the ridge demister semicanal of this device is arranged schematic diagram,
Wherein: 1 is the absorption tower, and 2 is the bottom spraying layer, and 3 is brace summer, and 4 is drain bar, and 5 are the draining mouth of pipe, and 6 is semi-canal type ridge demister, and 7 is the top spraying layer, and 8 is the demister supporting vertical plate, and 9 is semicanal.
Five, the specific embodiment
Provide a preferred forms of the present utility model below in conjunction with accompanying drawing.
The boiler smoke that enters absorption tower 1 contacts with loop slurry under bottom spraying layer 2 sprays in the absorption tower, finish preliminary sweetening process, enter semi-canal type ridge demister 6 then, flue gas obtains further rectification, contact with slurries or flushing water under top spraying layer 7 spray then, further purified, discharged the absorption tower by the absorption tower outlet at last.The ridge type structure that demister is made up of the two-layer semicanal 9 that staggers constitutes, gapped between the semicanal 9, lower floor's semicanal is symmetrical in the position in semicanal gap, upper strata, demister bottom is supported by brace summer 3, slurries under top spraying layer 7 spray or flushing water are with after flue gas contacts, fall on the semi-canal type ridge demister, slurries flow to the slurry channels that is made of drain bar 4 and demister supporting vertical plate 8 or tower wall along the semicanal inwall, flow to outside the tower through the draining mouth of pipe 5 then.
