Description

The Integrated Processing Unit that a kind of sea water desulfuration is used

The utility model relates to a kind of doctor solution after-treatment device that removes sulfur dioxide in flue gas, particularly relates to the Integrated Processing Unit that a kind of sea water desulfuration is used.

The common method that removes sulfur dioxide in flue gas has dry method, wet method, semidrying and seawater method etc.Simple use sea water desulfuration needs a large amount of seawater, and direct ratio strengthens with coal-fired sulphur content increase, otherwise sea water after desulphurization is acid, and not only etching apparatus discharges with the back but also will add in the alkaline matter.In seawater, add a small amount of alkaline matter earlier if give, as the useless ash of lime, calcium carbide mud, soda factory white clay, magnesium oxide, limestone powder or semi-dry desulphurization etc., both can improve sea water desulfuration rate and desulfurization capacity, be convenient to regulate pH again and remove heavy metal, also have the advantage of the treatment of wastes with processes of wastes against one another and two-way treatment.All aftertreatments such as aeration oxidation, pH regulator and/or separating clarifying must be carried out to sea water after desulphurization in these cases, in the hope of qualified discharge.At present, remove sulfur dioxide in flue gas with seawater and adopt big area aeration and a large amount of seawater neutralising arrangements, its shortcoming is that equipment is big, and power consumption is many, and oxidation efficiency is low, and low to the controllability of the pH of discharge water and heavy metal content.

The purpose of this utility model provides the Integrated Processing Unit that a kind of sea water desulfuration is used, and it can overcome the above-mentioned shortcoming of prior art.

The Integrated Processing Unit that a kind of sea water desulfuration is used has a pond body, it is characterized in that in this pond body that being separated out mixing/solarization air cell, oxidizing chamber, flocculating chamber, inclined tube settling pocket, clarifying chamber, spray successively by dividing plate converts chamber and decontamination chamber; Space by dividing plate top or bottom between the adjacent chamber is communicated with, and in mixing/solarization air cell and the oxidizing chamber ventpipe that is connected a plurality of air distribution heads is housed all, and mixing/solarization air cell and oxidizing chamber bottom also are equipped with insolubles and are returned/scum pipe; In the inclined tube settling pocket inclined tube is set, the bottom is communicated with the flocculating chamber, and top is communicated with the clarifying chamber, and the bottom is provided with shore pipe; Water jet standpipe is equipped with on the top in the spray chamber of converting; The decontamination chamber with on the ditch that confluxes link to each other; Be located at pond body upper limb on conflux and leave the slit between ditch and the pond body; Pond body lower edge is provided with down the ditch that confluxes; Under conflux ditch bottom be provided with water shoot.

The utility model has the advantages that compact construction, integrated, function is many, and cost is low, the space availability ratio height, and step-by-step oxidation is convenient to operation, and power consumption is few, the efficient height.

Below by implementing and description of drawings the utility model.

Accompanying drawing 1 is a plan structure synoptic diagram of the present utility model.

Accompanying drawing 2 is a side-looking structural representation of the present utility model.

The Integrated Processing Unit that this sea water desulfuration is used has a pond body 3, it is characterized in that being separated out mixing/solarization air cell 8, oxidizing chamber 9, flocculating chamber 10, inclined tube settling pocket 11, clarifying chamber 13 successively, spraying and convert chamber 15 and decontamination chamber 16 by dividing plate in this pond body 3.Space by dividing plate top or bottom between the adjacent chamber is communicated with.In mixing/solarization air cell 8 and the oxidizing chamber 9 ventpipe 7 that is connected a plurality of air distribution heads 5 is housed all, mixing/solarization air cell 8 also is equipped with insolubles with oxidizing chamber 9 bottoms and returns/scum pipe 4; In the inclined tube settling pocket 11 inclined tube is set, the bottom is communicated with flocculating chamber 10, and top is communicated with clarifying chamber 13, and shore pipe 12 is equipped with in the bottom; Spray is converted on 15 tops, chamber water jet standpipe 14 is housed; Decontamination chamber 16 with on the ditch 1 that confluxes directly be communicated with; Be located at pond body 3 upper limbs on conflux and leave slit 6 between ditch 1 and the pond body 3; The ditch 2 that under body 3 lower edges in pond are provided with, confluxes, its bottom outside is provided with 3 water shoots 17; The carrier of the upper and lower mobile moisture film of pond body 3 outer wall double as between the ditch 1,2 that confluxes; Be provided with leg 18 below the pond body 3.This device can be made steel construction or skeleton construction.

When using the utility model, can be placed on the above or below ground or semi-underground in ground.Acid seawater after the desulfurization enter with the alkaline matter emulsion mix/solarization air cell 8 in, mix and neutralize by air distribution head 5 air-blowing.Air-blowing oxidation once more in oxidizing chamber 9.Seawater flocculates by the oxyhydroxide of additional flocculating agents or self iron in flocculating chamber 10.The solid-liquid separation is taking place in inclined tube settling pocket 11.Seawater 13 enters spray and converts chamber 15 through the clarifying chamber, and fresh seawater is converted with jet-like spray downwards by the round on the water jet standpipe 14 simultaneously, forms fine foam.The basic oxidation of reducing substance in decontamination chamber 16, several dissolvings to the greatest extent of suspended particulates.This peace and quiet seawater enters the ditch 1 that confluxes after the slit 6 between bottom of trench and pool wall forms wall flowing water film, evenly flow to down the ditch 2 back dischargings of confluxing, and reaction further takes place to purify therebetween.In mixing/solarization air cell 8 and oxidizing chamber 9 calcium sulfite and undissolved alkaline matter by return/scum pipe 4 returns desulfurization unit continuously and utilizes, and the regular discharge waste residue.Here Ji Lei hydroxide (Asia) iron has katalysis to the oxidation of sulfurous acid (salt), also has certain flocculation coagulation effect.The throw out of flocculating chamber 10 and the accumulation of inclined tube settling pocket 11 bottoms is regularly discharged by shore pipe 12.Because the dissolving consumption acid that the bronsted lowry acids and bases bronsted lowry material is produced in the oxidation of sulfurous acid (salt) in the whole process takes place simultaneously, so but pH value basic controlling at 6.5-7.5, heavy metal is also taken away by body refuse because of the hydrolysis adsorption.PH, heavy metal and other main water-quality guideline generally can be better than three grades of seawater emission standards.
