Abstract
The utility model provides a de-capsulated filtering high-efficiency dust collector and comprises a bracket, a dust collector shell arranged on the bracket and a filtering bag arranged in the shell. A separator plate is arranged in the shell to divide the internal cavity of the shell into a dust removal chamber and a dust collection chamber, a filtering bag frame and a filtering bag arranged on the filtering bag frame are arranged between the separator plate and an air exhaust port, the filtering bag frame and the filtering bag are truncated cone-shaped, and an induction pipe is arranged above the separator plate. The device provided by the utility model is characterized in that: 1. the quantity of wind treatment is large; 2. filtering wind speed is high; 3. dust concentration of flue gas treatment can be more than 30g/m<3>; 4. dust removal efficiency is more than 99.5 percent; 5. the device has simple structure, easy processing and high effectiveness; 6. resistance loss is around 120mmH<2>O.
Description
(1) technical field
The utility model relates to a kind of separator, specifically a kind of gas-solid separating device, particularly a kind of dust arrester.
(2) background technology
The kind of present employed dust arrester is a lot, for example cyclone dust collector, fiber bag precipitator etc.But also there are many weak points in present employed deduster.For example handled air quantity can not be excessive, the rate of filtration is lower, dust removing effects is undesirable, complex structure, replacing and maintenance trouble etc.
(3) summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and treating capacity is big, good dedusting effect, the filter formula high-efficiency dust remover that takes off easy to maintenance simple in structure.
The purpose of this utility model is achieved in that it comprises support, rack-mount deduster housing, be arranged on the filter bag in the housing, in housing, be provided with the dividing plate that the housing inner chamber is separated into dirt pocket and dust storage chamber, be provided with filter bag framework and the filter bag that is installed on the filter bag framework between dividing plate and the exhaust outlet, filter bag framework and filter bag are truncated cone shape, and ingress pipe is positioned at the top of dividing plate.
The utility model can also comprise some architectural features like this:
1, is provided with flow deflector in the filter bag framework.
2, filter bag is outside equipped with the locking waistband.
3, exhaust ports is provided with guide ring, and filter bag and guide ring and dividing plate are tightly connected.
4, dividing plate is supported in the housing by muscle in length and breadth.
Dress of the present utility model mainly is made up of metal cellular filter bag framework, guide ring and the dividing plate etc. with certain rigidity of tubular shell, filter bag and support filter bag.Be provided with flow deflector in framework, this flow deflector can promote the filtration of tangential direction.Housing is made up of two and half cylindrical shells, and is cylindrical, and the channel partition into the landing dust is housed below in its chamber, and dividing plate is separated into two parts about dirt pocket and the dust storage chamber with the tube chamber, but two parts communicate up and down, also are airtight.Dusty gas enters dirt pocket by the ingress pipe that is positioned at the dividing plate top by tangential direction.Clean gas is drawn by the exhaust outlet of housing top.A few road locking waistbands are housed, in order to avoid air-flow starts filter bag between the upper and lower of filter bag.Ash bucket is arranged at the dust collection chamber bottom, and the ash bucket exit is connected with electronic unloading valve.
Dusty gas is under the effect of dirt source by air-introduced machine force feed or suction, in air inlet pipe and with certain speed, tangentially air-flow is introduced the dedusting chamber, originally air-flow becomes circular motion by rectilinear motion, rotation gas is made spirality from bottom to top along tube chamber wall and is moved to the top, the centrifugal force that dusty gas produces in rotary course, the grit of severe greater than gas got rid of to barrel, grit is in case contact with barrel, just lost inertia, grit just freely falls, when this burst outward turning air motion arrives the top, because bag becomes the space of truncated cone shape and tube top of chamber bigger than the portion of dirt pocket, the static pressure that produces along radius changes, the dusty gas that arrives the top is subjected to the effect of guide ring, just along filter bag surface rotation, from top to bottom move and produced interior eddy flow, the filter bag surface of dusty gas by the angle type almost meets at right angles and enters in the inside casing.Columnar housing can bear higher static pressure, this structure take off filter formula high-effective dust-removing device, can bear bigger filtration velocity, mainly be that flow deflector promotes that tangential direction becomes 90 ° to enter in the filter bag framework, utilize filter bag to filter dusty gas like this, obtained clean gas fully, the flue row who is directed to the housing opened upper end then is to atmosphere.
Owing to utilize the mandatory rotation descending motion of dusty gas along filter bag, the filter bag surface has certain angle and produces and carry out filtration relatively.No matter be to use non-woven or textile material as filtering material,, select proper all unrestricted as long as can be high temperature resistant, corrosion-resistant, wear-resistant.In addition, dust-contained airflow is spiral flowing on the surface of filter bag, when gathering certain thickness dust layer, can be destroyed by the gas kinetic energy that flows, dust is just fallen the bottom of dirt pocket, perhaps be suspended in the dirt pocket inner chamber, start unloading valve to certain hour and get rid of dust in the dust collection chamber.Therefore do not need ash disposal system one cover subsidiary body, this has not only simplified sack cleaner structural complexity in the past, huge property.Also save many power-equipments, saved certain energy.
The outstanding feature of device of the present utility model is mainly reflected in: it is big 1, to handle air quantity; 2, filtration velocity height; 3, the smoke treatment dust content can reach 30g/m
3More than; 4, efficiency of dust collection is up to more than 99.5%; 5, simple, the easily processing of device structure, benefit are big; 6, drag losses 120mmH
