Description
Technical field
The present invention relates to the maintaining method in converter dry dust removal installation, a kind ofly specifically prevent the converter evaporative cooler of fouling and prevent the method for fouling.
Background technology
Along with country is to the increasingly stringent of environmental requirement, steel mill's converter gas dedusting technology development, dry dedusting technology is subject to attention and the employing of each steel mill.Converter dry dedusting technology has that efficiency of dust collection is high, water-saving result good, energy conversion efficiency is high, working cost is low, energy consumption is few, floor space is little, be convenient to advantages such as administering and maintaining, be expected to the target realizing the steel-making of converter incapability, be identified as developing direction from now in the world.Evaporative cooler is the key equipment in converter dry dust-removal system, mainly lowers the temperature to flue gas, the process of modified and thick dedusting, and its operation conditions directly affects the efficiency of dust collection of electric precipitator below.Evaporative cooler inwardly projecting orifice water spray is uneven, or smoke moisture is excessive, or the evaporative cooler body design dust (Fe caused in flue gas such as unreasonable
2o
3, FeO, CaO, SiO
2and the compound etc. of complexity) be bonded together stick on the wall of evaporative cooler with water, cause wall scale formation.In actual production process, this is the operating technical barrier of dry-dedusting system, and the generation of scale formation can make outlet temperature for evaporation cooler rise, and affects the efficiency of dust collection of electrostatic precipitator below, and then affects the efficiency of whole dust removal process.The formation of schmutzband, decreases the open area of exhaust gases passes in evaporative cooler, causes resistance to flow to increase, and the energy consumption of blower fan can be made to increase.In addition, wall fouling in irregular shape, can cause flue gas vortex, reduces fluency and the homogeneity of flow of flue gas, is degrading dust removing effects.
Summary of the invention
The present invention be directed to the many deficiencies existed in prior art, one is to provide a kind of converter evaporative cooler that effectively can prevent fouling, and two are to provide the method that this evaporative cooler prevents fouling.
The technical scheme realizing the employing of foregoing invention object is: a kind of converter evaporative cooler preventing fouling, and comprise evaporative cooler body, two medium atomization nozzles are arranged on the ingress of evaporative cooler body,
Described evaporative cooler inner body wall is provided with good antiscale property coating;
Described evaporative cooler body interior is provided with ultrasonic vibration cleaning apparatus;
Described two medium atomization nozzles tilt to install along the inner periphery of evaporative cooler body entrance, and the setting angle of each nozzle is identical.
The angle of inclination of two medium atomization nozzle is clockwise.
The angle of inclination of two medium atomization nozzle is counterclockwise.
Ultrasonic vibration cleaning apparatus is arranged on the position of the easy fouling of evaporative cooler inwall.
A kind of method preventing the fouling of converter evaporative cooler, the method, based on evaporative cooler body, evaporative cooler body interior sidewall surface sprays good antiscale property coating, installs ultrasonic vibration cleaning apparatus in tactical deployment of troops water cooler wall inside, installed by same angular slope by all two medium atomization nozzles being arranged on evaporative cooler body ingress.
The angle of inclination of two medium atomization nozzle is all clockwise or is all counterclockwise, and angle of inclination is to ensure that in tower, flue gas is that cyclone mode flowing is as the criterion.
Ultrasonic vibration cleaning apparatus is arranged on the position of the easy fouling of evaporative cooler inwall.
Owing to have employed technique scheme, the present invention utilizes good antiscale property coating, ultrasonic vibration cleaning apparatus and changes the method for flue gas flow field and effectively to avoid evaporating water cooler fouling.Its unusual effect is also: good antiscale property coating spraying is simple, bonds firmly, do not affect flow of flue gas and heat transfer with wall; Ultrasonic vibration cleaning apparatus is easy for installation, ash disposal scope is large, effective, can dust that is comprehensive, that adhere to without the removing evaporative cooler wall at dead angle, and sound wave dust separator running cost and maintenance cost are very low, the work of energy on-line continuous, level of automation are high, reliable working performance; Change nozzle placement mode simply, after tiltedly spraying on evaporative cooler cooling, the impact of modified and thick dust removing effects not quite.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present invention.
Fig. 2 is the A direction view in Fig. 1.
In figure: evaporative cooler body 1, ultrasonic vibration cleaning apparatus 2, evaporative cooler body outlet 3, good antiscale property coating 4, two medium atomization nozzle 5, evaporative cooler body entrance 6.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
See accompanying drawing 1-2, this method of fouling that prevents disclosed in this invention is applicable to coverter pig evaporative cooler, be improve on the basis of conventional evaporative coolers, and in actually operating, carry out use restriction based on this improvement, thus the water cooler encrustation that effectively avoids evaporating.
Converter evaporative cooler after this improvement, comprises evaporative cooler body 1, ultrasonic vibration cleaning apparatus 2, evaporative cooler body outlet 3, good antiscale property coating 4, two medium atomization nozzle 5, evaporative cooler body entrance 6.Two medium atomization nozzles are arranged on the ingress of evaporative cooler body, and the outlet of evaporative cooler body is arranged on its body side.Improvement part is: one sprays good antiscale property coating in evaporative cooler inner body wall; Two are provided with ultrasonic vibration cleaning apparatus in evaporative cooler body interior; The inner periphery of two medium atomization nozzle along evaporative cooler body entrance tilts to install by three, and the setting angle of each nozzle is identical.
Based on the evaporative cooler after above-mentioned modified node method, the method (i.e. principle) of its good antiscale property is: converter gas enters evaporative cooler body by evaporative cooler entrance, the atomizing droplet sprayed with atomizing nozzle carries out mass transfer, heat transfer reaction, the angle of inclination of two medium atomization nozzle is clockwise or counterclockwise, the scope at its angle of inclination is to ensure that in tower, flue gas is that cyclone mode flowing is as the criterion, the atomizing droplet of the atomizing nozzle ejection of tilting drives flue gas rotational flow can add the residence time of flue gas, drive flue gas swirling motion together, reduce the topical hypothermia of tower wall, make drop near wall rapid evaporation, prevent the dust accumulation in atomizing droplet and flue gas, bonding, be attached on evaporative cooler wall and produce scale formation, in evaporative cooler inner body wall, even application has good antiscale property coating, and this coating can reduce converter along the adhesion of dust on evaporative cooler inwall wherein, does not hinder the flowing along it simultaneously, in addition, in the position of evaporative cooler inner body wall easy fouling, vibration of ultrasonic wave cleaning apparatus is installed, as body and outlet connection etc., this device can produce ultrasonic wave, ultrasonic wave can cause the dirty matter hardened on wall to follow wall to shake together, because the form of dirty matter is different from metal with elastic impedance, shear stress can be formed on interface between dirt matter and wall, cause hardening dirty matter fatigue on wall, crackle, loose, broken and come off, thus reach the object of antiscale, scale removal.
The above-mentioned relevant texture improvement in order to the water cooler fouling that avoids evaporating and method, the water cooler wall fouling that avoids evaporating that can be permanently effective, does not affect the efficiency of dust collection of converter dry dust-removal system simultaneously.
