Abstract
The invention is a horizontal humid static electricity dust catcher, belonging to environment protection technology field. It includes static electricity dust catcher box, ash box in current technology. A positive board and a negative board are assembled in the box, the positive boards are arranged in several rows vertical to the gas flow, and there has a gap between two adjoined boards which is used as smoke channel. The top of the positive board is arranged with a water nozzle for eliminating the ash on the positive board, the ash box is filled with water, forms the water seal avoiding the smoke shortcut. The invention upgrades the dust advancing speed greatly. The volume of the dust catcher is 1/4 of current catcher, and the cost is low.
Description
Technical field
The invention belongs to the environment protection equipment technical field.
Background technology
Existing electrostatic precipitator is by box-type shell, positive plate, negative electrode, vibrated system, and parts such as ash bucket are formed.The course of work of this electrostatic precipitator is that flue gas enters the deduster body, and the charged back of dust is adsorbed by anode, and the dust that accumulates on the positive plate falls into ash bucket through rapping, and cleaned gas is discharged by exhaust outlet.The deduster of this structure, positive plate are the capable settings of gentle levelling, easily produce secondary fly-up during rapping, and the flue gas of ash bucket easily passes through from the ash bucket short circuit of below, big spoke degree has reduced efficiency of dust collection, so existing electrostatic precipitator is bulky, involves great expense.And the efficiency of dust collection requirement is high more, and problem is obvious more.
Summary of the invention
The purpose of this invention is to provide a kind of positive plate layout, plate face deashing and ash bucket choked flow mode all with in the different electrostatic precipitator of prior art, to overcome the aforesaid drawbacks that exists in the prior art.
Technical scheme of the present invention comprises static electricity dust catcher casing, ash bucket.Positive plate, negative electrode in the casing, what changed is that positive plate is arranged setting perpendicular to air-flow more, between adjacent two the space is arranged in every row's positive plate, as exhaust gases passes.Forward and backward row's positive plate mutual alignment relation is the center in the space between two positive plates of row after the center correspondence of front-seat positive plate, and there is the water spout of removing dust stratification on the positive plate upper end of positive plate, and each is arranged negative electrode between the positive plate.Fill water in the ash bucket, the water surface exceeds the positive plate lower end, forms the water seal of avoiding the flue gas short circuit.
Using good effect of the present invention is that positive plate is arranged perpendicular to air-flow, can improve the dust into speed that becomes.The mode of utilizing water to dash is removed the dust stratification on the positive plate face, can suppress secondary fly-up in the situation of high wind speed and replenish the water of ash bucket choked flow water seal.And the ash bucket choked flow adopts positive plate there be not the mode of the water seal in the entry, can stop the flue gas short circuit in the ash bucket.Eliminate the factor that influences efficient from several aspects like this, improved the dust into speed that becomes greatly.Adopt said method, handle same flue gas and guarantee under the situation of identical efficiency of dust collection, the volume of deduster of the present invention is 1/4 of an existing electrostatic precipitator, cost is 1/3, and owing to do not had rotatable parts and rapping part, guaranteed the reliability of long-time running, and the reduction degree maintenance standard.
Description of drawings
Accompanying drawing 1 is front of the present invention broken section and overall schematic;
Accompanying drawing 2 is a vertical view cutaway drawing.
Embodiment
With the disposal ability in the existing technology is 12000m
2The electrostatic precipitator of/h is an example, and by technology in the past, conventional material selects flue gas circulation area 1m
2, the dimensional parameters manufacturing of length 2.4m, assemble case 1.Housing 1 bottom is an ash bucket 5.Two ends are air inlet 6 and gas outlet 7.Thick with 1mm, 260mm is wide, and the long stainless plate of 1700mm is manufactured positive plate 2, the high stile of 20mm of the oriented equidirectional in positive plate both sides.Positive plate is provided with four rows perpendicular to the flue gas flow path direction in housing, every horizontally-arranged is settled three, and front and rear row staggers, and adjacent two array pitch are from 320mm.The positive plate upper end is fixed on the housing, and the lower end is fixed on the crossbeam, and the crossbeam two ends are fixed on the housing.The equidistant tubular barbed wire negative electrode 3 of placing between two row's positive plates, the number of negative electrode are from advancing the mouth direction, 3 of first rows, 4 of second rows, 3 of the 3rd rows, 4 of the 4th rows.The same static electricity dust catcher of the fixing means of negative electrode.Establish flat-shaped nozzle 4 in the upper end of positive plate 2.Settle Sifangtai shape ash bucket 5 in housing 1 bottom, dress water in the ash bucket, the water surface surpasses positive plate lower end 100mm.Smoke inlet 6 and outlet 7 are connect smoke conveying duct.The present invention promptly assembles and finishes.
To be flue gas advanced through entering the mouth 6 to enter deduster by conveyance conduit the course of work of the present invention, and negative electrode 3 makes dust charged, the same prior art of the charged device of deduster.Charged dust is being adsorbed onto on the anode 2 under the effect of electric field and wind-force.Dust is adsorbed onto in the process of anode, water by the water spout ejection of positive plate upper end pours in the ash bucket 5, water spray pressure and injection flow rate are in use adjusted, and the grey aqueous mixtures that falls within the ash bucket is discharged by the ash releasing tube of ash bucket 5 bottoms, and clean gas is discharged to smoke conveying duct by outlet 7.
