Abstract
The utility model relates to a high-temperature smoke dust-removing filter. As a tank body, a main body is provided with an air inlet and an air outlet. The tank body is divided into an air chamber at the upper part and a ceramic candle type filtering unit at the lower part by a pattern plate. A pulse back-blowing system is arranged in the air chamber, a pressure sensor is arranged in the filtering unit, and a dirt removing opening with an electromagnetic valve is arranged at the bottom part and is directly connected with a dust cleaning chamber. The filtering unit adopts a candle type fiber membrane ceramic filtering element which can endure the temperature of 1,100 DEG C to the maximum degree and is sealed by graphite and a zirconium-contained alumina silicate fiber felt, the aperture is within 15 to 30mum, and hole gradient membrane materials are adopted for manufacturing. With reasonable structural design, good dust-removing effect and long service life, the renewable high-temperature smoke dust-removing filter is particularly suitable for high-temperature smoke treatment in a coal-fired power plant.
Description
Technical field
The utility model relates to the waste gas pollution control and treatment field, is specifically related to a kind of dust removal filter that is used in industries such as cement, metallurgy, electric power, kiln high-temperature flue gas purification.
Background technology
In recent years, China develops rapidly based on the heavy chemical engineering industry of resource, the energy, has become the first in the world big steel, cement, coal, chemical fibre producing country, second largest electric power, non-ferrous metal, chemical fertilizer production state.The companion has brought severe problem of environmental pollution, and the investment that China is used for environmental protection during "the 10th five-years" reaches 2.2% (GDP in 2004 is 13.65 trillion RMB) of GDP.Heavy chemical engineering industry atmosphere pollution is principal character with the high-temperature flue gas, and flue dust class particle is one of major control object.As control total amount rules, country revises successively to all kinds of boilers of industrial circle, the discharge value that stove is formulated, and is strict with and reduces discharge capacity.Main product in the market is electrostatic precipitation and bag-type dusting, and they are in the low temperature dedusting stage, does not occur but have good product as high-temperature flue gas discharged particle (flue dust) control technology.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provide a kind of high temperature resistant, thermal shock performance is splendid, fast at a high speed, the reproducible dust removal filter for high-temperature flue gas of filtering accuracy.
The purpose of this utility model is achieved through the following technical solutions.
A kind of dust removal filter for high-temperature flue gas comprises tank body, and there is air inlet the tank body side, and the gas outlet is arranged at the tank body top, by card tank body is divided into upper and lower two parts, i.e. the ceramic candle type filter element of the air chamber on top and bottom.Full-automatic pulse cleaning system is arranged in the air chamber, can carry out pulse backblowing regeneration at the characteristics of flue dust.Pressure sensor is housed in the filter element; Deashing chamber is arranged at the bottom, and deashing chamber is terminal for the sewage draining exit of magnetic valve is housed, and it directly is connected with deashing chamber.
Filter element is equipped with candle formula tunica fibrosa ceramic filter element, and the aperture is at 15-30um.Can be according to different autonomous selection of flue gas particle.Simultaneously, candle formula tunica fibrosa ceramic filter element is a hole gradient membrane material, has effectively reduced filtration resistance, improves filtering accuracy.1100 ℃ of the high-temperature resistants of the ceramic film filtering element of installing, thermal shock performance is fabulous, ten extremely cold very hotly do not ftracture.Ceramic film filtering element is by graphite and contain zirconium alumina silicate fibre felt seal, has well solved the problem of high temperature gas leakage.
The utility model has overcome the shortcomings and deficiencies of traditional filtrating equipment of flue gas, has the serviceability temperature height, the filtering accuracy height, and the rate of filtration is fast, and power of regeneration is strong, characteristics such as long service life, and realized automatic control, easy operating.Being specially adapted to coal-burning power plant's high-temperature flue gas administers.
Description of drawings
Accompanying drawing is the structural representation of the utility model dust removal filter for high-temperature flue gas.
Among the figure: 1, tank body, 2, air inlet, 3, the gas outlet, 4, card, 5, the ceramic candle type filter element, 6, pulse cleaning system, 7, deashing chamber, 8, sewage draining exit, 9, pressure sensor, 10, magnetic valve, 11, air chamber.
The specific embodiment
Referring to accompanying drawing, dust removal filter for high-temperature flue gas comprises: tank body 1, air inlet 2, gas outlet 3, card 4, ceramic candle type filter element 5, pulse cleaning system 6, deashing chamber 7, sewage draining exit 8, pressure sensor 9, magnetic valve 10, air chamber 11 and switch board 12.It is characterized in that whole tank body is divided into two parts up and down by card.The top of tank body 1 is air chamber 11, and the bottom of tank body 1 is a ceramic candle type filter element 5, and pressure sensor 9 is housed; The bottom is deashing chamber 7 and the sewage draining exit 8 that magnetic valve 10 is housed.At filter element 5 pressure sensor 9 is housed, by pressure sensor signal, control impuls blowback system 6 carries out blowback.At sewage draining exit 8 magnetic valve 10 is housed, in the beginning pulse backblowing,, opens sewage draining exit 8 by magnetic valve 10; After pulse backblowing finishes, close sewage draining exit 8.
Workflow is: high-temperature flue gas enters into tank body 1 by air inlet 2, the filter element 5 of flowing through, and magazine is left on pipe fitting outer, and clean gas enters into the air chamber 11 on top by pipe fitting, discharges by gas outlet 3.Have filtering layer when the pipe fitting surface, the air pressure of filter element can increase, and this is that pressure sensor 9 can be transported to the external control cabinet with this signal, by control system starting impulse blowback system 6, open sewage draining exit 8 simultaneously, blowback finishes, sewage draining exit is closed, and reenters in the circulation of filtration.
The utility model patent has modern design, and is simple in structure, good dedusting effect, and regeneration effect is strong, and the advantages such as long service life are specially adapted to the improvement of dust-laden high-temperature flue gas.
