Abstract
The utility model discloses a wet electric dust remover, comprising a housing, an outlet for gas purification is arranged at the top of the housing and an outlet for dust, water and residue is arranged on the bottom; an inlet for smoke and dust is arranged at the lower part of the housing. The utility model is characterized in that a porcelain bottle is arranged outside the housing, a cathode frame is arranged at the upper part inside the casing and the external cable is connected with the cathode frame by the porcelain bottle; a plurality of coronal lines are arranged on the cathode frame and a plurality of barbs are arranged on each coronal line; a water atomizing nozzle is arranged at the lower part inside the casing and a spray pipe is arranged on the anode plate. The cross section of the anode plate is quadrate or round and the anode plate is sleeve-jointed inside the dust remover casing.
Description
The utility model relates to environmental technology field, particularly relates to a kind of device of removing Industrial Stoves flue dust and dust.
Along with development of modern industry, often environment is produced and pollute, environmental issue more and more is subjected to great attention both domestic and external.But pollution abatement is technical also to be faced with many practical difficulties.For example, shaft kiln is the main process equipment of manufacture of cement, also is the main smoke contamination source in cement plant, owing to dust contained flue gas concentration, temperature, humidity change greatly, changes soon, and its dust size brings very big difficulty with very bigger than resistance fluctuation to treating flour dust.Therefore, in decades, the development of cement production enterprise is being perplexed in the shaft kiln dedusting always.At present, the water dedusting of employing, bag dedusting and dry method electric precipitation are all not ideal enough.The water efficiency of dust collection is low, the difficulty up to standard of gathering dust.Bag efficiency of dust collection height, but investment and operating cost height require harshness to vertical kiln operation, and the cement plant is difficult to accept.The dry method dust collection efficiency is also than higher, but vertical kiln operation required also very strict.And when flue-gas temperature was high, dust removing effects was poor, easily produced reentrainment of dust, and positive plate deashing difficulty is big, and investment is also overlapped partially, the operational reliability instability.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of wet electric dust-removing device is provided.Its efficiency of dust collection height, dust exhausting concentration is low, and reduced investment is good, reliable to shaft kiln calcination operational suitability.
Above-mentioned purpose of the present utility model can realize by following measure:
A kind of wet electric dust-removing device is provided, comprises a housing, the top of housing is the outlet of Purge gas, and the bottom of housing is the outlet of dust, water and slag; Lower part of frame is provided with the inlet of smoke dust of furnace kiln; Hull outside is provided with porcelain vase, and the epimere of enclosure interior is provided with cathode frame, and outside cable links by porcelain vase and cathode frame; Cathode frame is provided with many corona wires, and every corona wire is provided with a plurality of prickles; Hypomere in enclosure interior is provided with water atomizing nozzle; Positive plate is provided with sparge pipe.
The purpose of this utility model can also realize by following measure:
Adopt telescopic electric field structure, promptly adopting cross section is square or circular electric field positive plate, and socket is installed in the deduster enclosure interior.
Described corona wire employing diameter is 14～16 millimeters a stainless-steel pipe
Compared with prior art, the utlity model has following outstanding advantage:
1, the utility model adopts water power composite dedusting mechanism: water is to the flue gas spray for dust suppression, and humidification moistens matter, and the desulfurization defluorinate will capture than meal dirt; Electric precipitation will capture than fine dust and mist lacquer, and no reentrainment of dust need not rapping, but the sewage reuse, and the positive plate flushing water recycles.
2, the utility model provides the method electric dust collector, has the efficiency of dust collection height, and dust exhausting concentration is low, and reduced investment is to good, the reliable advantage of shaft kiln calcination operational suitability.For example: the actual use on No. 2 machine shaft kilns of Yuxi lotus pond cement two factories, through the monitoring of Yuxi environmental monitoring station, the flue dust dust exhausting concentration is 124.4mg/NM
3, be lower than state specified standards value (≤150mg/NM
3), the reduction of toxic emission is 1,344 ten thousand mark rice
3The reduction of the discharging of/year flue dust reaches 621.52 meters
3/ year.
3, the adaptability to various calcination, dry kiln is good, adopt telescopic electric field and ceramic insulation structure, invest low, operating reliability good, is the industrial furnace and the desirable cleaner of coal fired boiler of industries such as cement, metallurgy, chemical industry, has the good prospect of marketing.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof, but content of the present utility model is not limited to shown in the accompanying drawing.
Fig. 1 is a front view of the present utility model, and wherein the part is broken away;
Fig. 2 is the vertical view of device shown in Figure 1;
Fig. 3 is the A-A cutaway view among Fig. 1, and it has described described telescopic electric field cross section is square;
Fig. 4 is the schematic diagram of described circular sleeve formula electric field;
Fig. 5 is power supply aerial lug figure of the present utility model;
Below in conjunction with details and the operation principle of accompanying drawing detailed description according to the concrete device that the utility model proposes.
This device 1 comprises a housing 4, and the top of housing 4 is the outlet 9 of Purge gas, and the bottom of housing 4 is the outlet of dust, water and slag; The bottom of housing 4 is provided with the inlet of smoke dust of furnace kiln; Housing 4 outsides are provided with porcelain vase 3, and the epimere of housing 4 inside is provided with cathode frame 8, and outside cable 2 links by porcelain vase 3 and cathode frame 8; Cathode frame 8 is provided with many corona wires 7, and every corona wire 7 is provided with a plurality of prickles 6; Hypomere in housing 4 inside is provided with water atomizing nozzle 5; Positive plate 10,11 is provided with sparge pipe.Adopting cross section is square or circular electric field positive plate 10,11.And socket is installed in the inside of housing 4.Corona wire 7 employing diameters are 15 millimeters stainless pipe steel pipe.The outside cable of device with have commercially available constant-current source transformer (high-pressure electrostatic) now and connect and get final product.
During this device work, kiln gas is entered by the lower tangential of deduster 1, and is modified through the clear water spray for dust suppression of water atomizing nozzle 5, rise to the electric field in deduster stage casing then, dust and mist are captured on the positive plate 10,11, fall through the water flushing, the gas up to standard after the purification enters atmosphere.The sewage that deduster is accepted enters cesspool through sloping plate deposition and filtration, stirs also after filtering, and clear water recycles as positive plate dust wash water.
