What in general, the present invention solved is the recovery problem of the wet smog in the waste gas in the technological process.Up to now, reclaiming wet smog employed is rectangle or the cylindrical filter that fiber glass packing is housed.And,,, then adopt cylindrical filters owing to need carry out straighforward operation especially for the radioactive emission of wet smog and dried smoke-like for the very high radioactive emission of radioactivity energy more.This filter generally is made of filter frame and circular glass fiberfill.The diameter of filter and highly can choosing wantonly.Waste gas enters filter (this end and filter body seal, the other end are then with a lid sealing) by filter one end entrance, radially by fibrage, leaves the filter core then.This superimposed fiber separator can spray at work, makes filtering medium itself reach cleaning by washing out the particulate of staying on the fibrage.On this filter, respective nozzles and feed feeder are the parts of filter shell, when renew cartridge more, take off together with one of filter core.The liquid of spray not only is sprayed onto the exhaust gas entrance of filter, and drenches waste gas outlet, and because the waste gas short interruption may take place, liquid must be discharged respectively.In order to reach the separating degree height, make the pressure loss in the filter less again simultaneously, thereby the speed of waste gas by fiber glass packing must keep within limits.Like this, operational filter area just defines the max-flow flux of waste gas by filter.Cleaning device about filter bed is introduced such as having in DE-OS 30 12 911.
The spray system of dress in the sort of known filter core of introducing does not previously have.The nozzle that is used for the hydro-peening filtering medium is the part of filter shell.In case spray nozzle clogging just must cost great number cost be changed the filter shell, because the filter shell generally is to use in the life-cycle of entire equipment.In addition, in a kind of like this shell, filtering layer is fixed on the filter frame two ends, so just can not lay the multilayer filter bed, to enlarge filter area.
Therefore, task of the present invention is: create a kind of cartridge described above.Compare with known filter core, this filter core has enlarged filter area on the one hand, has improved the jetter of cleaning filter area on the other hand again.
For solving this task, the present invention advises adopting the filter core of following architectural feature, and the circular filtering medium of this filter core is between two concentric tubes and leave the space, and the tangent plane of filtering medium is the U font that two legs makes progress; Cleaning device is positioned at top cover inside, and its spray direction sees it is the annular inner room that sprays between the U font two legs from inflow direction down, and this cleaning device is the part of filter case integral body; Be provided with central dividing plate between annular space top that two pipes form and closure head, dividing plate is positioned on the outer tube, and between the top cover certain distance is arranged, and central authorities leave the connector of inlet plenum on the central dividing plate, also stay an opening for annular inner room in addition.
The further feature of filter core also comprises, feed feeder is set below top cover, and radially shower is installed on the feed feeder, the nozzle direction of shower down, nozzle is positioned at annular opening top, and sprays in the annular inner room.As the wet separator that can clean automatically, the filter core of this structure is by technological process waste gas being forced reach the wet smog of recovery by the filtering layer filler of being made up of glass fibre cotton.Because the shape of this filter is two cylindrical filtering layers that are provided with one heart, the two links to each other with same thick glass fibre cotton packing again in the bottom, thereby filter core can clean from top to bottom with nozzle.At this moment, waste gas enters from bottom to top by the air inlet of filter, and arrival radially turns to behind the top, arrives the distributor chamber of two cylindrical fibre layers then.When waste gas passed fibrage, wet flue dust was left in the cellucotton filler, and waste gas then continues to flow downward, by the annular opening discharge strainer of filter bottom.When the pressure reduction in the filter reached a certain setting because of the obstruction of filtering medium, filter core just automatically or manually carried out hydro-peening by filter integral component cleaning device of the present invention with cleaning liquid.During hydro-peening, the flue dust that is trapped on the filter medium is washed out by water, and together leaves filter with water.Therefore filter core obtains cleaning, and can continue to finish new task according to the rules.According to the present invention, itself all belongs to the part of filter core liquid distributor here and nozzle.
Other details below will be illustrated by means of diagram.This figure is the filter vertical section schematic diagram as the automatic cleaning type wet separator.
Filter mainly is made of shell 1, and shell is made up of two concentric tubes 2 and 3, and filtering medium 4 is installed in 5 li of the annular spaces of formation between pipe 2 and 3.In the bottom of pipe 2 and 3 base 6 is housed, top cover 7 is equipped with at the top.Base 6 centres have air inlet 8, need purified waste gas 9 enter by air inlet in 10 li of the inlet plenum of pipe in 3.
In addition, arranging exhaust outlet 12 on the circumference of bottom 6, exhaust outlet is connected with annular space 5, discharges by exhaust outlet through purified waste gas 11.The hold-down ring 13 of a band seal 14 is arranged at the base bottom, they to also belonging to this filter shell but other parts that do not add description compress.
