The internal bypass filter bag protector is low in cost; the detection and protection are fast and correct while no stop or off line is needed; the cost is reduced to the maximum limit; and time is saved.
Description
Technical field
The utility model relates to a kind of sack cleaner internal bypass filter bag protective device.
Background technology
In recent decades; Enhancing day by day along with the pushing forward comprehensively of China's economic construction, continuous progress in science and technology and people's environmental consciousness; Sack cleaner is as a kind of cleaner of environmental protection efficiently and production process equipment, in the growing field extensive use.
Because the reliability of pulse dust cleaning and the excellent properties of high energy property and filtrate, sack cleaner have become the main flow of bag type dust removing technology development in the world.Especially in developed country, bag type dust removing technology is widely used in cement dry method revolution kiln hood, kiln tail, coal-burning boiler, iron and steel, chemical industry, casting etc.
Because the Industrial Stoves that produce waste gas are under the abnormal running state; Flue-gas temperature, humidity, oxygen content in the entering deduster exceeded the ability to bear of filter bag of dust collector; Cause filter bag to shrink, burn, stick with paste the generation of phenomenons such as bag, shorten the service life of filter bag when light greatly; Filter bag of dust collector was lost efficacy, deduster can't normally be moved.
Therefore filter bag is the heart of sack cleaner, and the length in its life-span is directly connected to the quality of deduster, adopts the protective device of new material, new technology to prolong service life of filter bag as far as possible, has become a big problem of current sack cleaner industry.Since traditional filter bag protective device be on deduster air inlet flue, add automatic water jetting heat sink, cold wind adjusting device or outside the bypass flue; Cause getting into moisture increase in the flue gas in the deduster after adding the automatic water jetting heat sink; Because filter bag has an awful dread of water and separates and stick with paste bag, therefore will shorten the service life of filter bag greatly; Add and to cause getting into that oxygen content increases in the flue gas in the deduster after the cold wind adjusting device, the rising of oxygen content causes filter bag oxidized, shortens the service life of filter bag equally greatly.After adding outer bypass flue, construction costs is compared the internal bypass device to be increased a lot, and clogging also appears in outer bypass flue easily.
The utility model content
The utility model purpose is to provide a kind of sack cleaner internal bypass filter bag protective device, and installation cost is low, detects and protect quick and precisely to need not to shut down to roll off the production line, and has reduced cost to greatest extent, saves time.
To achieve these goals; The utility model adopts following technical scheme: a kind of sack cleaner internal bypass filter bag protective device; Comprise casing, ash bucket, air-purifying chamber, winding-up guard system, filter bag, bag cage, air intake adjusting valve door, equal wind water conservancy diversion wind isolation board; On air intake adjusting valve door and pipeline that ash bucket is connected, be provided with the air inlet sampled point, the air inlet sampled point is connected with thermometric hygrometric oxygen determination instrument inlet port through data wire, and thermometric hygrometric oxygen determination instrument is controlled display system with PLC and is connected; All on the wind water conservancy diversion wind isolation board internal bypass air-out switch valve being installed, the air-out switch valve is installed on air-purifying chamber.
Comprise that also remote detection, numeral show, acoustic-optic alarm.
Also comprise the flue-gas temperature, humidity, the oxygen content detector that are connected with PLC control display system.
Casing is provided with the observation access panel.
Internal bypass air-out switch valve cylinder is provided with base support and extension bar.
Internal bypass air-out switch valve is provided with graphite asbestos cord sealing ring at the valve plate lower plane.
Internal bypass air-out switch valve is provided with the centralized positioning device.
The utility model installation cost is low, detects and protect quick and precisely to need not to shut down to roll off the production line, and has reduced cost to greatest extent, saves time.
The utility model specifically has following advantage: the first, and this device has functions such as remote detection, numeral demonstration, sound and light alarm, and automaticity is higher, and operating cost is lower.The second, this device has flue-gas temperature, humidity, oxygen content detector, when the flue-gas temperature that detects the sack cleaner air inlet, humidity, when oxygen content is unusual; PLC control display system is opened internal bypass air-out switch valve; Close the air-out switch valve simultaneously, make flue gas change direction, avoid filter bag; Directly discharge, thereby effectively protect filter bag through internal bypass air-out switch valve.The 3rd, this device is provided with the observation access panel, observes internal bypass air-out switch valve ruuning situation, thereby carries out in time, repairing exactly, guarantees that deduster normally moves.The 4th; This device internal bypass air-out switch valve cylinder is provided with base support and extension bar; When deduster moves; Can avoid flue gas directly to contact with seal by base support and extension bar, avoid having prolonged the service life of cylinder greatly because the corrosive gas that contains in the too high or flue gas of flue-gas temperature produces cylinder damages with cylinder rod.
The utility model is adaptable across metallurgy, chemical industry, and coal, building materials, papermaking, with serious pollution industrial waste gas such as non-ferrous metal is administered required sack cleaner.
