Abstract
Kiln afterbody vertical electric dust-collecting, it has broken the traditional architecture general layout, the collection humidification, gather dust, the chimney Trinity.This device is made up of the vertical square tube dust collection electric field of upper end open body 8, pole plate 9, corona discharge electrode 10.Cylindrical shell upper end suitable for reading is provided with presses gas baffle 11, is evenly hanging corona discharge electrode 10 under the baffle plate respectively, and hang in the lower end of rainhat 15 by high-voltage insulating system 12 respectively the baffle plate upper end, and high pressure inlet wire cable is connected on presses the gas baffle upper end.Because the insulation of corona discharge electrode and high pressure inlet wire all is to implement in pressing gas baffle upper end natural environment, not influenced by cylindrical shell discharge flue gas suitable for reading, has guaranteed the reliability service that electricity gathers dust.
Description
The present invention relates to the principle and the device of kiln afterbody vertical electric dust-collecting.
All adopt horizontal bag collection and horizontal electricity to gather dust at large-scale kiln afterbody both at home and abroad at present, they all exist the common problem of oneself separately, and the shortcoming of bag collection is that the pressure loss is big, can stop up cloth bag live when serious, and dust collection device can't normally be moved.The shortcoming of gathering dust about horizontal electricity is: need establish conditioning Tower and chimney, invest too greatly, in addition, because insulation environment bad easy dewfall flashover etc. are all multifactor, the voltage in the electric field can only be delivered to below the 4.5kv, so dust collection effect is all not very good.
The objective of the invention is to provide a kind of kiln afterbody vertical electric dust-collecting principle and device that need not set up conditioning Tower and chimney.
The object of the present invention is achieved like this, the dust collection electric field body is processed into the shape of vertical square tube upper end open, being fixed on inside the electric field body of pole plate equalization, then corona discharge electrode through high-voltage insulating system with press the cigarette vapor baffle, hanging is in the centre of electric field body internal polar plate respectively, and the seal upper end is connected with the drop hanger that rainhat is divided into.Bottom at the dust collection electric field body establishes dust-settling compartment, the side of dust-settling compartment is provided with into fume ducts, be provided with a plurality of (operating) water nozzles above the conduit entrance, certainly, nozzle also can be pacified to air-introduced machine inlet duct front, to satisfy the requirement that blower fan allows inlet temperature, nozzle is opened what, record the temperature decision by the thermal resistance in the dust-settling compartment, temperature is high more, and the nozzle of unlatching is many more.When temperature was lower than the minimum temperature of setting, all nozzle Close Alls illustrated that flue dust has not at this moment needed decreasing temperature and increasing humidity.The concrete course of work is when flue dust is introduced in the dust collection electric field body by blower fan, at first give the flue dust humidifying cooling through the spray of (operating) water nozzle, wherein a part of dust combines with the globule and falls in the flue-dust retainer, the rest parts flue dust enter be attracted in the electric field body on the pole plate and corona discharge electrode on, by vibrator it is shaken again and fall in the flue-dust retainer, draw off through conveying worm.Process water gathers dust and electricity gathers dust, and the dust more than 95% is all regained, and remaining cigarette vapour is discharged naturally by electric field cylindrical shell pressure cigarette suitable for reading vapor baffle lower end, thereby has reached kiln afterbody vertical electric dust-collecting small investment, the purpose that dust collection effect is good.
Concrete structure of the present invention is provided by following examples and accompanying drawing thereof.
Fig. 1 is the principle of the proposition according to the present invention and the side cutaway view of device.
Fig. 2 is the principle of the proposition according to the present invention and the front view of device.
Describe in detail according to the principle of the present invention's proposition and the details and the working condition of device below in conjunction with Fig. 1 and Fig. 2.
This device has flue-dust retainer (1), dust-settling compartment (2), advance flue dust skirt (3), (operating) water nozzle (4), thermal resistance (5), pole plate hole (6), electric field body vibrator (7), the dust collection electric field body (8) of vertical square tube upper end open, pole plate (9), corona discharge electrode (10), press cigarette vapor baffle (11), high-voltage insulating system (12), drop hanger (13), high pressure inlet wire cable (14), rainhat (15), rainhat backing material (16), the spacing jockey of internal heat type High-Voltage Insulation rapping (17), discharge auger conveyer (18).
Concrete working condition, when kiln afterbody flue dust through air-introduced machine guide to this device advance in the fume ducts mouth (3) time, at first to pass through the spray of (operating) water nozzle (4), make the abundant humidifying cooling of flue dust, wherein a part of dust is because the effect of humidification, dust-settling compartment to be entered (2) back flow velocity is slack-off, and natural subsidence is to flue-dust retainer (1) lining.Flue dust temperature in the dust-settling compartment (2) is recorded by thermal resistance (5), realizes setting with control (operating) water nozzle (4) through control instrument and opens what of quantity.Though played certain dust collection effect by humidifying cooling, but most of flue dust still is retracted in vertical dust collection electric field body (8), to be adsorbed on pole plate (9) by electric field body vibrator (7), dust on the corona discharge electrode (10) shakes and falls in the flue-dust retainer (1), by conveying worm (18) powder of regaining is drawn off, through the two poles of the earth remaining cigarette vapour discharge naturally below vertical dust collection electric field cylindrical shell pressure cigarette suitable for reading vapor baffle of gathering dust.In order to guarantee the good insulation between corona discharge electrode (10) and electric field body (8) and the pole plate (9), be provided with below high-voltage insulating system (12) and press cigarette vapor baffle (11), corona discharge electrode (10) is hung in the electric field body through overvoltage cigarette vapor baffle (11) insulation.High pressure inlet wire cable (14) on the corona discharge electrode also is connected with pressing the cigarette vapor baffle on press cigarette vapor baffle (11), so, whole inlet wire is all implemented near natural environment in the baffle plate top with insulation, has fundamentally avoided the dewfall of insulating materials and high pressure inlet wire cable surface to climb arc discharge.Guaranteed the reliability service of kiln afterbody vertical electric dust-collecting equipment.
The purpose of invention is that it integrates humidification, lowers the temperature, gathers dust, chimney. Therefore, have following characteristics: one, be grassroot project reduce cost units up to a million, this investment only is 1/3rd of traditional pattern. Two, without the humidification tower, made things convenient for the transformation of old kiln. Three, save a large amount of auxiliary devices, reduced operating cost. Four, the own reliability height of equipment, simple, intuitive, maintenance is little and make things convenient for. Five, floor space is very little.
Therefore, can say not only in China, comprise that countries in the world all are revolutions to gather dust method and construction pattern aspect of the tradition of kiln afterbody.
