Abstract
The utility model discloses a plate type mechanical air cooler, which is composed of a cooling box body, and a cooling blower which is connected with the cooling box body through a pipeline. A plurality of flow guiding cooling plates which are fixed in the frame type cooling box body are formed into a plurality of cooling tube bundles which are arranged in a through pipeline and thin plate way. A high temperature section and a lower temperature section are formed into a series double passage structure. After entering the utility model to be cooled and dust removed, high temperature smoke gases are exhausted to atmosphere. A cooling pipe wall is acted by the air pressure of an inner and an outer cavities to generate oscillating movement with oscillation amplitude of from 0 mm to 5 mm, and fine dust can be automatically cleared down to fall into a dust hopper which is positioned at the lower part of a box body. The cooling and the heat transfer effects of the utility model are obviously better than the cooling and the heat transfer effects of a tube type and a scraping plate type air cooler. The utility model has the advantages of low cost, and automatic dust removal. The utility model is especially suitable for high temperature dust removing systems of an electric furnace and a rotary furnace.
Description
Technical field the utility model relates to a kind of mechanical air cooler, specifically a kind of electric furnace that is used for, the board-like mechanical air cooler in the converter dedusting line.
Background technology steel mill electric furnace or converter (AOD stove) produce a large amount of high temperature dust flue gases in steelmaking process, if these flue gases directly are disposed in the atmosphere, will cause serious environmental to pollute.Therefore, people--after----water-cooled flue cools indirectly, send into high-temperature flue gas again mechanical air cooler and force row discharging again after blowing cooling, the dedusting indirectly through the combustion chamber all the time.
Existing mechanical air cooler is two kinds of tubular type and scraper-types.The tubular type mechanical air cooler is that many misarrangements row formula arranges that the cooling heat transferring coefficient is little because of cooling tube bundle, and effectively heat transfer area is little; Tubular type each several part blowing heating degree inequality, easily dust stratification and not easy-clear in the pipe, the free wxpansion telescopicing performance is poor, and service life is short.On the other hand, the weight of tubular type FU film-cooled heat is big, and cooling blower power is bigger, and it is on the high side therefore to cool off body.
The relative tubular type of scraper-type air cooler heat transfer area has increased, but this structure is because scraper plate and heat-transfer pipe face are necessary gapped, otherwise the attrition tube face, therefore the dust on the heat-transfer pipe will produce grey fouling (thermal) resistance, heat transfer coefficient reduces, and effectively heat transfer area also will reduce, and heat output descends.In addition, the scraper plate ash-cleaning type is provided with a cover mechanical ash removing mechanism, motor, reductor, transmission mechanism, the palpus manual maintenance, and manufacturing and maintenance cost are higher.
The summary of the invention the purpose of this utility model provides a kind of board-like mechanical air cooler, in order to overcome the deficiency of above-mentioned existing like product, increase substantially effective heat transfer area of mechanical air cooler, automatically remove the sidewall dust stratification, and effectively reduce weight of equipment, power of motor and reduction cooling body equipment price.
In order to achieve the above object, the utility model has adopted following technical proposal:
This board-like mechanical air cooler is by cooling off casing, forming with the cooling blower that the cooling casing is connected by pipeline, some water conservancy diversion coldplates that are fixed in the cooling casing form several cooling tube bundles, this cooling tube bundle is arranged for the straight channel thin board type, forms the binary channels series-mode frame by high temperature section and low-temperature zone two parts.
In order to realize above-mentioned purpose better, be welded with several vibration limit sticks between cooling tube bundle, leave the spacing gap of vibration between close mutually vibration limit stick; Cooling tube bundle is made up of inner chamber and exocoel, high-temperature flue gas be go out on enterprising or under advance next-out; Cooling blower one end is equipped with silencer; The cooling lower box is equipped with several ash buckets, and is respectively equipped with spiral unloading valve and hopper wall vibrator.
Adopt the board-like mechanical air cooler of this technical scheme to compare with the tubular type mechanical air cooler, unit film-cooled heat weight of equipment is light by 30%, the big 10-15% of complex heat transfer coefficient, effectively heat transfer area is big by 30%, cooling fan flow is little by about 20%, the cooling blower power of motor reduces about 15%, and cooling body price reduces about 18%; Compare with scraper plate ash-cleaning type mechanical air cooler, weight of equipment reduces on the board-like unit are, and heat transfer coefficient increases, and effectively heat transfer area also obviously increases, and the cooling blower power consumption reduces, and can move non-maintaining substantially operation reliably and with long-term.
Description of drawings Fig. 1 is a structural representation of the present utility model.Fig. 2 is a cooling unit internal structure schematic diagram.Fig. 3 is the A-A direction cutaway view of Fig. 1.Fig. 4 is the B portion enlarged drawing of Fig. 3.
Specific embodiment the utility model is by cooling off casing 1, forming with the cooling blower 2 that cooling casing 1 is connected by pipeline, cooling casing 1 adopts the framework Welding Structure, material is Q235, is installed on the H shape steel bracket 5, wherein is provided with high-temperature flue gas in cooling casing 1 bottom and imports and exports each one.Cooling casing 1 side is provided with cold gas and imports and exports each one, and cooling air is blown into by cooling blower 2, and cooling blower 2 air-out reduced pipes are steel plate, and cooling blower 2 and 1 of casing of cooling are equipped with silencer 3, and silencer 3 is the micropunch formula, and the noise decibel is less than 85dB; Cooling casing 1 bottom is equipped with several ash buckets 4, and is respectively equipped with spiral unloading valve and hopper wall vibrator, and cooler ash bucket 4 hangs with refractory material.
The some water conservancy diversion coldplates 6 that are fixed in the framework cooling casing 1 form several cooling tube bundles 7, this cooling tube bundle 7 is arranged for the straight channel thin board type, form the binary channels series-mode frame by high temperature section and low-temperature zone two parts, about 1650 * 9000 * 2 * 12 groups of high temperature section, board selection 16Mng or 15Mo3, about 1650 * 9000 * 2 * 12 groups of low-temperature zone, sheet material is 20g; Cooling tube bundle 7 inner chambers are walked the high temperature flue gas, and exocoel is walked cold gas, high-temperature flue gas be go out on enterprising or under advance next-out; 7 of cooling tube bundles are welded with several vibration limit sticks 8, and 8 close of vibration limit sticks leave spacing gap mutually, realize that vibration is spacing.
High-temperature flue gas is after cooling, a large amount of dusts easily amass in the cooling tube inwall, when equipment moves, exocoel gas pressure in the cooling tube wall is subjected to, automatically produce the oscillating movement of 0---5mm amplitude, tiny dust stratification is removed automatically, this vibrates the heating surface not damaged, dust stratification under coming off falls into the ash bucket 4 that is arranged in the below, and the fume emission behind the cooling and dedusting is to atmosphere.
