Description

A kind of bag-type dust collector and its application process
Technical field
The invention discloses a kind of bag-type dust collector and its application process, it is related to environmental protecting device design field.
Background technology
Filtered more than the current processing to dusty gas using sack cleaner, its operation principle is by connecting tube Dusty gas is incorporated into the casing of sack cleaner by road, and dusty gas is moved by the graviational interaction of air-introduced machine to cloth bag, powder Dirt is attracted on cloth bag, and cleaned gas is discharged out of cloth bag, so as to reach the effect of air cleaning.But because existing Sack cleaner gas connection pipe is directly connected on the upside of the middle casing of sack cleaner, the ash-laden gas entered in casing Body in the presence of air-introduced machine can flow velocity become big, pour the casing of sack cleaner at a high speed in the presence of inertia force, enter High speed dusty gas part in cartonning body after cloth bag from upper box gas discharge outlet directly through discharging, another part dust-laden Gas is impacted after cloth bag from the decline of casing air inlet side, is then arranged by gas after Bag filter from the gas discharge outlet of upper box Go out.Because the dusty gas that high speed is entered in casing is very strong to the scouring force of cloth bag windward side, cause cloth bag windward side can not Stick dust, and substantial amounts of dust is gathered in the lee face of cloth bag.The lee face dust of deduster can be so caused to adsorb blocked up, Gas can not pass through, and will necessarily so increase blowback frequency;Windward side is then because of good permeability, and absorption affinity is strong, and tiny grit can be straight Connect through cloth bag and be discharged into air.Causing the purification efficiency and efficiency of dust collection of existing sack cleaner can not improve.It is wherein above-mentioned to lack It is trapped in flue gas dry cleaning processing system and shows the most substantially, because being needed in flue gas dry cleaning processing system by flue gas Pernicious gas carry out adsorption cleaning using adsorbent, adsorbent is generally all kinds of dust, and the adsorbent of addition needs to reclaim profit With making the adsorbent skewness on cloth bag for these reasons, it is just directly logical that part pernicious gas is not exposed to adsorbent Cloth bag enters air-purifying chamber, the catharsis not reached, and the gas permeability of windward side preferably, adsorb by the little particle that need to partly reclaim Agent enters air-purifying chamber also through cloth bag, and organic efficiency is low.
The content of the invention
The present invention solves the technical problem of:For conventional cloth bag deduster in use, dusty gas is straight Connect and wash away cloth bag, cause cloth bag to damage, and efficiency is low during blowback, need multiple blowback, cause the problem of energy consumption is higher there is provided A kind of bag-type dust collector and its application process.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
The top is provided with below air outlet, air outlet outside a kind of bag-type dust collector, including dust collector box body, dust collector box body Provided with air inlet, dust collector box body lower half is provided with ash bucket, and hopper bottom is provided with discharging opening, and dust collector box body is pacified by bottom The support frame of dress is fixed on the top inside ground, dust collector box body and is provided with back-blowing device, and back-blowing device is located above cloth bag, It is characterized in that:It is provided with inside cloth bag inside helical blade, and dust collector box body and is provided with baffle plate in cloth bag installation site side, Baffle plate fan blade is evenly distributed with baffle plate;
During using described bag-type dust collector, dusty gas enters dust collector box body by air inlet, under airflow function, band Equally distributed baffle plate fan blade is rotated above dynamic baffle plate, it is to avoid dusty gas impact direct to cloth bag and cause cloth bag to damage, together When larger particles directly fall into ash bucket, by the later dusty gas of baffle plate under suction function, through cloth bag, make gas and Dust is separated in cloth bag surface, and the clean gas after filtering after cloth bag through air outlet by discharging, in use, when When cloth bag surface laying dust thickness reaches 2~4mm, drive the helical blade in cloth bag to rotate by back-blowing device, and produce centrifugal force, The dust for making cloth bag surface laying dust fall into ash bucket, ash bucket is discharged through discharging opening.
Described helical blade is fixed on inside cloth bag using central shaft, and central shaft is free to rotate.
Described baffle surface is evenly distributed with baffle plate fan blade, and baffle plate fan blade is fixed in baffle plate circular hole by bearing, and Baffle plate fan blade can 360 ° freely rotate.
Described baffle plate fan blade material therefor is 304 stainless steel plates that thickness is 2~4mm.
Described back-blowing device uses compressed air for source of the gas, and compressed air pressure is 0.6~0.8MPa.
Material used in described helical blade is 302B stainless steels.
The beneficial effects of the invention are as follows:
(1)The sack cleaner that the present invention is developed in use, using the cushioning effect of the baffle plate with baffle plate fan blade, subtracts Percussion of the slow dusty gas for entering sack cleaner directly to cloth bag, can be prevented effectively from dusty gas to the direct of cloth bag The cloth bag loss caused is washed away, maintenance of equipment frequency is reduced, effectively reduces manpower and materials;
(2)The sack cleaner blowback efficiency high that the present invention is developed, during blowback, is driven in cloth bag using purge gas and pacified The helical blade of dress is rotated, and is produced centrifugal force, is reached and the high-efficient cleaning of cloth bag all angles laying dust is removed, and have benefited from baffle plate fan blade Interception function, most crude particle can be made to fall directly into ash bucket, it is to avoid excessive coarse granule is adsorbed in cloth bag surface, influence blowback Effect, in use, can be such that cloth bag surface laying dust falls into ash bucket, save energy consumption, with wide without multiple blowback Wealthy application prospect.
