The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Such as Fig. 1.A kind of air box impulse bag-type dust remover, comprise casing and ash bucket 11, described casing top is provided with electromagnetic impulse valve 1, lift valve 2 and compressed air line 3, box house is separated into air-purifying chamber 4 and filter chamber's two parts by card 19, it is characterized in that the filter chamber is divided into filter chamber 8 and filter chamber 9 by the exhaust gases passes plate, be provided with the gas feed 7 that communicates with filter chamber 8 on one side of described casing, be provided with the gas vent 10 that is communicated with filter chamber 9 on the opposite side of casing, described filter chamber is communicated with ash bucket 11.Described filter chamber 8 and 9 inside, filter chamber are equipped with case chamber dividing plate 5 and gas-flow deflector 6, and described case chamber dividing plate 5 is vertically set on inside, filter chamber, and described gas-flow deflector 6 is inclined at inside, filter chamber.Described ash bucket 11 comprises ash bucket inspection opening 12, supporting leg 13 and star-like discharger 14, and described star-like discharger 14 also is connected with conveying worm 15.Described ash bucket 11 quantity are 2.Described exhaust gases passes plate is provided with valve 16, valve 17, valve 18 from top to bottom successively.Be provided with filter bay assembly in the described filter chamber.
Dusty gas enters deduster by gas feed 7, is entered respectively filter chamber 8 and filter chamber 9 by gas-flow deflector 6 guiding, and whole filter chamber is separated into filter chamber 8 and filter chamber 9 by the exhaust gases passes plate, can process tolerance according to the Various Seasonal adjustment.Winter, the valve 16,18 of exhaust gases passes plate is closed, valve 17 is opened, each case chamber of deduster is divided into the form of two parts series connection, after dusty gas is processed through filter chamber 1, enter filter chamber 2 again and further purified, the rear gas of processing directly is discharged into indoor by gas vent, reduced indoor thermal loss in winter.In summer, the valve 16,18 of exhaust gases passes plate is opened, and valve 17 is closed, and each case chamber of deduster becomes again parallel form, processes also corresponding increase of tolerance.Simultaneously, according to the difference of winter and summer processing tolerance, deduster disposes two Fans, in the winter time, enables the blower fan of little air quantity, in summer, enables the blower fan of Wind Volume.Avoid also can saving the wearing and tearing of power consumption and minimizing blower fan simultaneously owing to using frequency conversion fan air quantity and the unstable dust pelletizing system that causes of blast normally to move.
Deduster case chamber is separated into air-purifying chamber 4 and filter chamber by card 19, and filter bag is installed on the card.Compare with the filter bag material, grieshoch is more fine and closely woven.In fact, little grit is caught by grieshoch, otherwise just can pass filter bag.Therefore, new filter bag will have imperceptible grit to penetrate filter bag and escape when just coming into operation, and form the pinniform cigarette at throat, and after the cloth bisque formed, the pinniform cigarette namely disappeared.
Spray into the air supply of filter bag by the opening time decision of the air pressure in the air accumulator and impulse electromagnetic valve.The pressure regulator valve indication of system and control deashing air pressure, pressure arranges lowlyer, and is less to the wearing and tearing of filter bag, under the prerequisite that guarantees ash-removal effect, should air pressure be transferred to minimum as far as possible.
The time compole that winding-up continues is short, directly being that electromagnetic impulse valve 1 reaches the fast reaction time: the compressed air compressing in the air accumulator triggers diaphragm and main film is that electromagnetic impulse valve 1 keeps closed condition, under the excitation of magnetic valve, produce pressure reduction at the triggering diaphragm, diaphragm lifts, main film one side air releases, and main film lifts under differential pressure action, and the air accumulator compressed air enters middle casing and pours filter bag.
The quick compressed air stream of undershoot in filter bag has formed the dust that the unexpected radial deformation of filter bag relative pocket cage gathers the filter bag outer surface and has come off.Electromagnetic impulse valve 1 is when foment not, and air releases the place closes, and air pressure resets diaphragm, and electromagnetic impulse valve is closed.
The design of ash bucket reduces to greatest extent turbulent flow and prevents reentrainment of dust.The ash bucket inspection door is used for the inspection to ash bucket inside and filter bag bottom.During deduster work, the ash bucket inspection opening must not be revealed.When the ash bucket inspection opening is opened, safeguard procedures must be arranged.The high temperature dust may cause serious scald and fatal harm, and therefore, before the unlatching ash bucket ash bucket inspection opening, the PLSCONFM ash bucket has emptied or ash is cooled off.When the ash bucket inspection opening is opened, can not stand in the inspection opening dead ahead, when having the high temperature dust to go out, personnel answer the escape unharmed passage.Ash bucket must not be used for storing dust, and excessive dust might be adsorbed onto on the filter bag again, causes the too early damage of excessive Pressure Drop and filter bag.Note at any time the indication of ash bucket material level, prevent excessive dust stratification.
Last dust is carried by conveying worm 15, star-like discharger 14 is set at the ash hole place, star-like discharger 14 can make conveying worm 15 discharge dust evenly, continuously, more stable with gas, the solid protected in the deduster, thereby make the deduster normal operation, the upper and lower part air pressure of star-like discharger 14 can be cut off and plays the effect of lock gas, reduction air leak rate of air curtain, assurance efficiency of dust collection again simultaneously.
