Abstract
The utility model discloses a waste gas filter-bag device, which can improve the blowing effect, save the energy source and reduce the production cost, wherein a flue gas inlet and a flue gas outlet are arranged on a cylinder body; compressed air bags are communicated with Venturi blowing pipes; the Venturi blowing pipes are communicated with filter bags; the air inlets of the filter bags are communicated with the flue gas inlet in the cylinder body; a plurality of chambers are arranged inside the cylinder body, and each chamber is provided with the compressed air bag, the Venturi blowing pipe and the filter bag; the air outlet of each chamber is communicated with the flue gas outlet through a stop valve. According to the utility model, the original on-line blowing operation is changed into off-line blowing operation, and when soot blowing is needed for the filter bag of one chamber, the stop valve of the chamber is closed while the other chambers operate normally, so that on the premise of not affecting the production, the blowing system of the chamber is started for soot blowing, and the blowing effect is guaranteed as the flow is stable during blowing and cleaning.
Description
Technical field
The utility model relates to a kind of waste gas filter bag device, is mainly used in collecting carbon powder dust useful in waste gas.
Background technology
The effect of producing 3.0 ten thousand tons of hard (carbon) black production line waste gas bag hoses per year is waste gas and the carbon powder dust of collecting the wet particle carbon black of rotary dryer inner drying.Because content in waste gas has a large amount of water vapours, vapour content, in 50% left and right, makes the exhaust of waste gas bag hose filter bag not smooth, directly affects the normal production of carbon black and contaminated environment.When the production load of the drum type brake waste gas bag hose now using in the time producing super-normal structure black is larger, as produce N121, N134, N234, N375, because the granulation water yield is larger, required dry larger by tail gas amount, air capacity, the water vapour amount therefore producing in dry run is also larger.Especially can cause waste gas filter bag device load sharply to increase in winter, two seasons of spring.Be mainly reflected in smoke inlet pressure rise, smoke inlet pressure, more than 1.2Kpa, causes comminutor blanking undesired; affect the normal operation of granulating and drying system; drying machine also can emit ash fouling environment, in this case, is forced to reduce black reactor load and maintains production.After research, main cause is that drum type brake waste gas bag hose upper box is not cut apart, and is online winding-up by analysis, and while causing winding-up cleaning, air turbulence and injection tube length are distributed inequality, greatly impact winding-up effect; Add the long filter bag bottom carbon black " bridging " that easily causes of filter bag.
Summary of the invention
The technical problem that the utility model solves is to provide one and can improves winding-up effect, saves the energy, reduce production costs waste gas filter bag device.
The technical solution of the utility model completes like this, waste gas filter bag device, comprise cylindrical shell, smoke inlet, exhanst gas outlet, filter bag, compressed air bag, venturi gas blow pipe, cylindrical shell is provided with smoke inlet, exhanst gas outlet, compressed air bag is communicated with venturi gas blow pipe, venturi gas blow pipe is communicated with filter bag, the air inlet of filter bag is communicated with the smoke inlet on cylindrical shell, in cylindrical shell, be provided with several chambers, each chamber is provided with compressed air bag, venturi gas blow pipe, filter bag, gas outlet set on each chamber is communicated with exhanst gas outlet by stop valve.
Further preferred embodiment, described chamber has four.
Further preferred embodiment, described cylindrical shell is square.
Further preferred embodiment, described stop valve is pneumatic stopping valve.
Technique effect of the present utility model is, change off-line winding-up into by original online winding-up, in the time that the filter bag of one of them chamber need to blow ash, close the stop valve of this chamber, other chamber keeps normal operation, and in the situation that not affecting production, the injection system that starts this chamber blows ash, steady air current during because of winding-up cleaning, has guaranteed winding-up effect.By the experiment of a year, after using the utility model to produce, carbon black output can improve approximately 5.7%; Calculate according to two production lines, can increase production carbon black 30000 tons/bar × 2 × 5.7%=3420 ton the whole year.Calculate by carbon black power consumption per ton 537.2 KWH described in the report of designing unit, save electric weight 3420 tons × 537.2 KWH/ton carbon black=1837224 KWH, amount to standard coal 0.1229kgce/ KWH × 1837224 KWH=226tce.The pressure decreased of smoke inlet of the present utility model is 0.5-0.8Kpa, has ensured that carbon black blanking is unimpeded, has extended the service life of filter bag, and comminutor blanking also can normally be worked.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail, waste gas filter bag device, comprise cylindrical shell 6, smoke inlet 7, exhanst gas outlet 1, filter bag 5, compressed air bag 4, venturi gas blow pipe 9, cylindrical shell 6 is provided with smoke inlet 7, exhanst gas outlet 1, compressed air bag 4 is communicated with venturi gas blow pipe 9, venturi gas blow pipe 9 is communicated with filter bag 5, the air inlet of filter bag is communicated with the smoke inlet 7 on cylindrical shell 6, cylindrical shell 6 is interior by midfeather 11, diaphragm plate 10 is separated into 4 chambers, each chamber is provided with compressed air bag 4, venturi gas blow pipe 9, filter bag 5, gas outlet set on each chamber is communicated with exhanst gas outlet by stop valve.
For increasing the area in cylindrical shell, improve and blow grey effect, cylindrical shell 6 is made as to square.
For conveniently controlling opening and closing of stop valve, stop valve is made as to pneumatic stopping valve.
When operation, carbon black waste gas enters in cylindrical shell 6 from smoke inlet 7, then enter into respectively in the filter bag in each cavity, discharge by exhanst gas outlet 1 through the gas outlet of each cavity again, the carbon powder dust filtering out drops in the collecting bin 12 of cylindrical shell 6 lower ends, enters into next equipment process by dust inlet 8.
