Description
Technical field
Ceramic filter-element dust collector of the present invention is specifically related to the cleaner that a kind of filtration contains the high-temperature gas of solid impurity, belongs to the cleaner technical field.
Background technology
At present, domestic many industries, as metallurgical, generating, pottery, smelting and chemical industry etc. annually all will be discharged a large amount of high-temperature gases, and these high-temperature gases are to be fuel with coal or heavy oil mostly, all can produce the high-temperature gas of a large amount of dust-ladens in combustion process.The characteristics of these dusty gases are: stickums such as flue-gas temperature height (generally greater than 400 ℃), dust concentration height, soot dust granule are thin, tar are many, and therefore the easy dewfall of low temperature adopts existing dust collecting process to be difficult to satisfy and purify requirement.Such as, fiber bag precipitator commonly used exists heatproof problem (250 ℃ of maximum operating temperatures) and corrosion-resistant problem (acidifying), as adopting dust settling pocket technique, must lower the temperature to high-temperature gas, then can increase handled exhaust gas volumn if adopt the adding cold air to lower the temperature; The high temperature cyclone dust collector is that foreign particle place to go efficient below the 10 μ m is lower to diameter, even adopt multistage dedusting, its removal effect does not reach 98% yet, electrostatic precipitation exists that power consumption is big, dust removing effects is unstable, and high-temperature gas also need be reduced to about 150 ℃ of the suitable running temperatures of deduster; Wet dust removal then not only can cause the waste of heat energy, and the while can be caused shortcomings such as secondary pollution, the energy consumption of water is big again.More than all reasons cause the tens billion of tons of present China annual discharging atmosphere elevated temperature heat gas, these elevated temperature heat gases are owing to contain a large amount of grits and pernicious gas, directly discharging, serious atmosphere pollution can be caused on the one hand, a large amount of thermal waste can be caused on the other hand.
Summary of the invention
Ceramic filter-element dust collector of the present invention, the technical problem that solve have provided a kind of high temperature resistant, corrosion resistance, deduster rapidly and efficiently.
In order to address the above problem, ceramic filter-element dust collector of the present invention, its main technical schemes is: ceramic filter-element dust collector, mainly by housing 1, ceramic filter device 2, pulse cleaning system 3 and soot cleaning system 4 are formed, the structure of ceramic filter device 2 is: card 5 is fixed on the inwall of housing 1, card 5 is provided with card hole 6, the lower end 8 of ceramic element 7 extend in the housing 1 from card hole 6, lower end 8 is by fixture 10 and housing 1 are fixed together down, the upper end 9 of ceramic element 7 links to each other with card 5, and upper end 9 is fixed together with card 5 by last fixture 11.
The structure of above-mentioned last fixture 11 is: at fixture 12 of the card hole of card 56 upper fixed, the upper end 9 of fixture 12 and ceramic element 7 cooperates together.
The structure of above-mentioned last fixture 11 can also be: at fixture 12 of the card hole of card 56 upper fixed, being provided with high temperature resistant, acid proof sealing ring 13 above the card hole 6 of card 5 and between the upper end 9 of ceramic element 7, above upper end 9, be connected with camphane pressure ring 14.
The structure of above-mentioned following fixture 10 is: pipe collar 15 is fixed on the lower end 8 of each ceramic element 7, and steel wire 16 is made reticular pattern, and steel wire 16 is fixed together with housing 1.
Above-mentioned ceramic element 7 is a kind of hole graded ceramics fiber composite film filtering element.
Its operation principle is: it is indoor that dust-laden high-temperature gas (coal gas of high temperature, flue gas etc.) flows into ceramic filter through air inlet pipeline, radially infiltrate each filter element (ceramic element 7) inner chamber, and in pipe, importing the clean gas collecting chamber vertically, last clean high-temperature gas is discharged by outlet pipe.In filter process, the part grit of high temperature dust gas is deposited in gradually on the outer surface of ceramic filter element and forms ash cake, increase along with ash cake thickness, increase falls in the pressure on the ash cake, need utilize cold high pressure gas that ceramic filter tube is carried out blowback cleans, ash cake is periodically removed from the ceramic filter element outer surface, realized the online regeneration of ceramic filter element, ceramic filter element just can be removed grit with remaining valid.Detection link at air inlet pipeline and outlet pipe is installed high-temp pressure sensor respectively, and the pressure of importing and exporting is measured in real time, when turnover pressure reduction reaches setting value, opens the magnetic valve in the controlling unit, oppositely cleans.
Refractory ceramics filter-element dust collector of the present invention is compared with existing deduster has following technique effect: 1. fast, the high efficiency of the rate of filtration: the filtration velocity of ceramic filter-element dust collector is generally 2～6m/min, and the filtration velocity of traditional sack cleaner can only reach 1.2～1.5m/min, like this in the identical time, the ability of ceramic element filter process foreign gas of the present invention is 2～4 times of common fiber bag precipitator, has improved the operating efficiency of deduster accordingly.
2. simple in structure, easy to use: the structure of ceramic filter device 2 is: card 5 is fixed on the inwall of housing 1, card 5 is provided with a plurality of cards hole 6, the lower end 8 of ceramic element 7 extend in the housing 1 from card hole 6, lower end 8 is by fixture 10 and housing 1 are fixed together down, the upper end 9 of ceramic element 7 links to each other with card 5, upper end 9 is fixed together with card 5 by last fixture 11, the mechanism at other positions and traditional fiber bag precipitator are basic identical, will descend fixture 10 to fix when dispatching from the factory, only ceramic element 7 need be packed into during installation and go up fixture 11 and following fixture 10, unclamp fixture 11 and following fixture 10 during replacing, take out ceramic element 7 then and change and get final product.
3. long service life, good filtration effect: the lower end 8 of ceramic element 7 is by fixture 10 and housing 1 are fixed together down, the upper end 9 of ceramic element 7 links to each other with card 5, upper end 9 is fixed together with card 5 by last fixture 11, thereby it is more firm that ceramic element 7 is connected, because ceramic element 7 has high temperature resistant and corrosion acid and alkali-resistance, and the foreign particle of diameter below 10 μ m had good filter effect, and the cloth bag filter core of common fiber bag precipitator can not be high temperature resistant and the corrosion of soda acid, and can not filter the foreign particle of diameter below 10 μ m substantially.Therefore, ceramic filter-element dust collector long service life, good filtration effect.
4. applied range, use cost is low: ceramic element 7 can be at high temperature, have under the rugged environment of Acidity of Aikalinity gas and move, maximum operating temperature can reach 900 ℃, maximum working pressure can reach 3Mpa, efficiency of dust collection can reach 99.9%, because the long service life of ceramic element 7, more the frequency of renew cartridge is 1/5th of a common fiber bag precipitator, thereby makes the use cost of ceramic filter-element dust collector only be 1/2nd of common fiber bag precipitator.
