The specific embodiment
For further setting forth the utility model diaphragm whistler wave dust remover, do more detailed explanation below in conjunction with embodiment.
Referring to Fig. 1, the utility model diaphragm whistler wave dust remover, comprise whistle body 1 and acoustic conducting pipe 2, acoustic conducting pipe 2 stretches in the whistle body 1, and its tail end is pressed the whole diaphragm 5 of a titanium alloy and not perforate, and this diaphragm 5 is embedded on the inwall of whistle body 1, whistle body 1 is divided into two cavitys, the front is a high pressure chest 3, and the back is the low-pressure cavity 4 of band passage 7, and pressure-air inlet 6 is left in the side of high pressure chest 3.Acoustic conducting pipe 2 is tubaeform, connects into complete acoustic conducting pipe 2 by the inner catheter 2A that is in high pressure chest 3 with the outer catheter 2B that is connected with ring flange.
The tail end diameter of inner catheter is 35mm, and the diameter of diaphragm is 140-160mm, and thickness is 1.3-1.9mm, and acoustic conducting pipe calculates by following formula

When high pressure chest 3 did not feed high pressure gas, diaphragm 5 was pressed in the afterbody of acoustic conducting pipe 2, the air flue of blocking-up high pressure chest 3 and acoustic conducting pipe 2; When high pressure gas enters high pressure chest 3, force diaphragm 5 crooked and leave the afterbody of acoustic conducting pipe 2, high pressure gas enters acoustic conducting pipe 2 by high pressure chest 3; In case high pressure gas enters acoustic conducting pipe 2, the high pressure in the high pressure chest 3 releases, and the conducting of high pressure chest 3 and acoustic conducting pipe 2 is blocked in diaphragm 5 resilience under self elastic force effect once more; High pressure gas is set up high pressure at high pressure chest 3 again, and compressing diaphragm 5 leaves the afterbody of acoustic conducting pipe 2.So repeatedly, producing nearly sinusoidal wave sound wave is sent by the horn mouth of acoustic conducting pipe 2.
The design of existing two models of the utility model diaphragm whistler wave dust remover at present, a kind of is SY15 type diaphragm whistler wave dust remover, the diameter of diaphragm 5 is 140-160mm, thickness is 1.3-1.9mm, the length of acoustic conducting pipe 2 is 1100mm, and the outlet bore is 380mm, and the atmospheric pressure that adds high pressure is 0.3-0.5Mpa, the sinusoidal wave frequency of the high sound intensity that diaphragm whistler wave dust remover produces is 150Hz, and the sound intensity can reach 148.1db (referring to Fig. 5).
The acoustic conducting pipe segmentation is installed, and furnace wall perforate φ 225 is installed, and concrete the installation seen Fig. 3.One flange sleeve 9 is installed on body of wall 8, and the stage casing of acoustic conducting pipe 2 is installed in the flange sleeve 9, with 11 fillings of insulation filler, covers follower 10 then on every side, and the front and back end and the whistle body 1 that connect acoustic conducting pipe again get final product.
Another kind of SY30 diaphragm whistler wave dust remover, the diameter of diaphragm 5 is 140-160mm, thickness is 1.3-1.9mm, the length of acoustic conducting pipe 2 is 540mm, the outlet bore is 255mm, and the sinusoidal wave frequency of the high sound intensity that diaphragm whistler wave dust remover produces is 300Hz, and the sound intensity can reach 148.1db (referring to Fig. 5).
Not segmentation of acoustic conducting pipe, furnace wall perforate are φ 278.Fig. 4 is seen in its installation.
Certain large enterprise's denitration furnace, blow-on is just serious because of dust deposit in furnace less than one month, had a strong impact on the out of stock effect of denitration furnace catalysis, so the installation dust remover has been selected by enterprise.Steam sootblower has been installed at first, but it is bad to blow grey effect, has the dead angle, many places, places many places, catalyst place in the middle of the wallboard and block.
The utility model diaphragm whistler wave dust remover is adopted in the back.Because the space, workshop is limited, diaphragm whistler wave dust remover is installed in the small space of furnace wall and workshop between the walls, has saved working space; Because the utility model diaphragm whistler wave dust remover sine wave, low frequency, the high sound intensity SATT is slower relatively, sphere of action is wider, under with the effect of lesser amt diaphragm whistler wave dust remover, removed dead angle dust stratification in the stove, destroyed the middle dust stratification of catalyst wallboard at a distance, realized online ash removal automatic ash removing operational mode, make denitration furnace can keep normal operation for a long time, improved denitration effect, realized target for energy-saving and emission-reduction.
