Description
The utility model relates to a kind of high-voltage electrostatic dust separator that is used for chimney and exhaust equipment system.
Contain a large amount of dusts in the waste gas that the chimney of the industrial enterprise that have and exhaust equipment are discharged; cause dust pollution to surrounding environment; country's " Law on Environmental Protection " has stipulated certain index to the dust content of the waste gas that industrial enterprise discharge, and dust content must install deduster additional above index.The dedusting method that adopts mainly contains water dedusting, cyclone dust removal, bag dedusting and electrostatic precipitation etc. at present.Wherein the electrostatic precipitation Operation and Maintenance is more convenient and be widely adopted, and this deduster mainly is made up of high voltage source, anode and negative electrode, and it is cylindric that anode generally adopts, and negative electrode adopts a cathode line to be placed on the home position of cylinder.Perhaps, anode adopts oval tubular, and negative electrode adopts 2 cathode line to be symmetrically distributed in the cylindroid.Dusty gas passes through in cylinder or cylindroid, and dust accumulates on the anode under the effect of static.The Electric Field Distribution of this dedusting method is more reasonable.But, when the processing air quantity is big, just need the number of increase cylinder or cylindroid, so not only equipment volume is huge, floor space big, be difficult to layout, and, the manufacturing process complexity, the space that surrounds between cylinder and the cylinder can not be used for exhausting-dusting, the waste steel.In addition, adopt this dedusting method in order to reduce the number of cylinder or cylindroid, adopt wide spacing between the general anode and cathode, after anode control of dust thickness surpasses certain numerical value, electric-field intensity between the anode and cathode is weakened and influence dust removing effects, for addressing this problem, must increase the anode ash removal equipment for flapping, so more increased the difficulty of mounting arrangements, and rapping is also influential to the life-span of equipment, sometimes large-area dust comes off simultaneously and may cause flicker discharge between the anode and cathode, causes reentrainment of dust.Because there are the problems referred to above in this electrostatic precipitator technology, has limited it to large scale development.
The utility model is a kind of novel electrostatic deduster that designs for the shortcoming that overcomes above-mentioned electrostatic precipitator technology, and it has broken the confinement of cylindrical shape and oval anode, and the shape of antianode is improved, and makes it can be to large scale development.
Technical solution of the present utility model is, a kind of high-voltage electrostatic dust separator, and it is made up of with the negative electrode 4 that is connected with power supply 10 deduster power supply 10, the tubular anode 3 that is connected with power supply 10, and negative electrode 4 is installed in the anode 3 and is vertical with the cross section of anode 3.Its special character is that the cross section of anode 3 is square.
The cross section of anode 3 of the present utility model is a square, and negative electrode 4 is single polar curve, and is installed in foursquare center.
The cross section of anode 3 of the present utility model also can be rectangle, and negative electrode 4 is 2 cathode line, and symmetry is installed in the rectangle.
The anode of traditional electrostatic precipitator adopts cylindric and oval tubular, mainly is in order to make relatively symmetry of Electric Field Distribution, to be more perfect theoretically like this, but not have this necessity on engineering at all, and is big to the sharp especially little fraud of large-scale electrostatic precipitation especially.Anode of the present utility model adopts square, negative electrode adopts polar curve to be installed in the anode, the distribution of electric field is asymmetric so theoretically, anode is eager to excel from the nearer part electric-field intensity of negative electrode, the better dust removal effect that these are local, and away from the part of negative electrode, for example four angles, electric-field intensity will be weak, and these local dust removing effects are just less better.But according to the characteristics of fluid, when gas flowed in anode, because that the power of stagnating is stained with by limit portion is bigger, flow velocity therefrom weakened around the mind-set gradually, and a large amount of dusty gases pass through from the centre, and near the gas flow rate that passes through four angles is very slow.In addition, because the effect of turbulent flow, what dust neither straight ahead in anode, the dust in the place that electric-field intensity is more weak may be gone to the stronger place of electric-field intensity in flow process.The asymmetric influence to dust removing effects of electric field is minimum, adopts square anode can satisfy requirement on the engineering fully.
Anode of the present utility model simplifies manufacturing process owing to adopted cube structure greatly, honest material under the steel plate is welded together get final product.If when the air quantity of handling is big, the anode of many cube structures can be combined, their adjacent parts can be used same block plate, have saved many steel.It is little that a plurality of side's body anodes are combined the floor space of combining than a plurality of cylindric or oval tubular anodes, arranges simply, brings great convenience to construction and installation.The anode of the side's of employing body can suitably reduce the distance between anode and the negative electrode, electric-field intensity is strengthened, the unlikely dust removing effects that the influences when thickness of control of dust increases, control of dust thickness just can come off under the effect of gravity after surpassing certain numerical value automatically, thereby save the anode rapping apparatus, make simplified equipment, working service is convenient.
