Abstract

A process and apparatuses for carrying out the same are described for liquid filtration, in which during the filtration process the filter is cleaned off at intervals of time and the resulting sludge is backwashed. <IMAGE>

Description

Zaŕízení pro filtraci kapal.iny sestává z filtračního prostoru a komore 10 pro odkalování,které jsou oddelený kulovýra kohoutem 1. Filtrační prostor obsahuje filtr 2.,který se pravidelné Čistí, Jestliže se dosáhne mezního zanesení filtračního prostoru 2 kalení, uvedou sehsory 11 ve spojení s regulačním zaŕízením 12 pomociThe liquid filtration device consists of a filter chamber and a blowdown chamber 10 which are separated by a ball valve 1. The filter chamber comprises a filter 2 which is regularly cleaned. with the aid control device 12

-3signálu do činnosti kulový kohout 1, ktorý uvolní spojení ke komore 10, do které se raúže vypustit vlhký kal* Komora 10 je spojená kulovým kohoutem 1 s filtračním prostorera Komora 10 disponuje s volným výplnchovým orgánem 15 jakož i kulovým kohoutem 2 s vynášecím potrubím 8, pro kal a potrubím 6 pro zpčtný proplach ,které jeou z jejioh strany spojený s regulačním zaŕízením 12 . V tomto potrubí £ je uppoŕádán regulovatelný kulový kohout 2, jakož sito 13 pro zadržovaní kalu a orgán 14 pro zpčtný pro* plaoh.The chamber 10 is connected by a ball valve 1 with a filter space. The chamber 10 has a free filling element 15 as well as a ball valve 2 with a discharge pipe 8. , for sludge and a backwash line 6 which are connected from its side to a control device 12. An adjustable ball valve 2 as well as a sludge retention sieve 13 and a backflush member 14 are arranged in this line.

Jestliže se kulový kohout 1 otevr.e, a vlhký náklad kalu se dostane do komory 10, tak se kulový kohout 1 opét zavŕe.Po té co se kulový kohout 1 zavrel,otevŕe se kulový kohout 2 a pomoci orgánu 15 pro volná proplachování dôjde k volnému proplachu.Volné proplachování se provádí pomooí vzduohu,který se pro tento účel používá.Kal se zadrží filtrem popŕípadé sitovým prvkem 1^., eluční kapalina teče po prúchodu sitovým prvkem 1^ potrubím 6 pro zpétný proplach do zásobní nádrže.If the ball valve 1 is opened, and the wet sludge load enters the chamber 10, the ball valve 1 closes again. After the ball valve 1 is closed, the ball valve 2 is opened and the free flushing organ 15 The free flushing is carried out by means of the air used for this purpose. If the sludge is retained by the filter or the screen element 1, the elution liquid flows after passing the screen element 1 through the backwash line 6 into the storage tank.

Po ukončení volného proplachování se kulový kohout zavŕe.Otevfením kulového kohoutu se muže kal usuôený pomoci vzduohu zpčtnč propláchnout pomoci orgánu M pro zpétný proplach,který je uspoŕádán z hlediska smeru zpčtného propla.chování pred sítera 13 a tak se muže dostat potrubím 3. pro vyriešení kalu k dalšímu zhodnocení.Na konci pochodu zpčtného proplachováníse kulový kohout 2 opét zavŕe,Upon completion of the free flush, the ball valve is closed. By opening the ball valve, the dried sludge can be backflushed by means of a backwashing organ M arranged in terms of the backflush direction in front of the sieve 13 and thus can be reached via line 3 for solution. At the end of the backwashing process, the ball valve 2 closes again,

U jiné forma provedeni je kulový kohout 1 otevŕen tak dlouľo,až z komory 10 pro odkalování pííjde od eensoru 11 signál ke kulovéreu kohoutu 1, který uvede tento do činnosti,na žákladé dosažení mežního naložení komory 13 kalem,čímž dôjde k uzavŕení spojení mezi filtračním pxostorem a komorou 10 až do dokončení pochodu odkalování .Po té co se kulový kohout 1 zcivŕel, odohráva se poohod odkalování vylíčený u pŕedchozího pŕí4kladu provedení t pri zac&ování plne schopnosti filtraoe.In another embodiment, the ball valve 1 is opened until the blower chamber 10 receives a signal from the sensor 11 to the ball valve 1, which actuates it, to achieve an intermediate loading of the chamber 13 by sludge, thereby closing the connection between the filter pxostorem and the chamber 10 to purge the completion of the operation as .After the ball valve 1 zcivŕel, draining taking place with poohod portrayed in the previous embodiment pŕí4kladu z and t at full capacity and filtraoe ed.

V jednom dalším príkladu provedení Je komora 10 pro odkalování opatrená kulovými kohouty 1,2,3 . Tento príklad má ozŕejmít, že se takovéto odkalovací zaŕízení múze inotalovat v libovalnýoh cykleoh zaŕízení.Jestliže se do'sáhne mezního naložení kapaliny kolem,uvede sensor 11 ve spojení s regulačním zaŕízením 12 pomooí signálu do činnosti kulový kohout 1 Komora 10 pro odkalování Je opatrená orgánem 15 pro volný proplaoh, jakož i kulovým kohoutem 2 s potrúbim-pro vynáôeni kalua potrubím 6 pro zpétný proplaoh,které jsou samy o sobé spojený s regulačním zaŕízením 12. V tomto vedení 6 pro zpetný proplaoh. je uspoŕádán regulcvatelný kulový kohout £ jakož i sito 13: pro zadržení kalu a orgán 14 pro zpetný propľ.ach.In another embodiment, the sludge chamber 10 is provided with ball valves 1, 2, 3. This example is intended to illustrate that such a blowdown device can be inhaled in a free cycle device. If the limit loading of the liquid is reached, the sensor 11 in conjunction with the control device 12 actuates the ball valve 1 with the signal 1. 15 for the free flushing as well as the ball valve 2 with a pipe for the discharge of the sludge through the back-flushing line 6, which in themselves are connected to the control device 12. In this back-flushing line 6. a controllable ball valve 4 as well as a sieve 13 for holding the sludge and a backfill organ 14 are provided.

Jestliže se kulový kohout 1 otevŕe, a vlhký náklad kalu se dostane do komory 10 , tak se zavŕe opát kulový kohout 1 . Po té oo se kulový kohout 1 zavrel,otevŕe se kulový kohout 2 a dôjde k volného proplachovaní pomoci orgánu 15 pro volný proplaoh. Volné proplaohování se provádí vzduchem,který se pro tento účel používá.Kal se zadrží filtračním prvkem popŕípadé sitovým prvkem 13 , retenční kapalina teôe po prúohodu sitovým prvkem 13 potrubím 6 pro zpétný proplaoh do zásobní nádrže.If the ball valve 1 is opened, and the wet sludge load enters the chamber 10, the ball valve 1 is closed again. Thereafter, the ball valve 1 is closed, the ball valve 2 is opened and free flushing is performed by the free flushing organ 15. The free purging is carried out with the air used for this purpose. The slurry is retained by the filter element or the sieve element 13, after returning through the sieve element 13 through the line 6 for backwashing into the storage tank.

Po ukončení volného proplaohování se kulový kohout 2 zavŕe. Otevŕením kulového kohoutu 2 3Θ múže suchý kal propláohnout vzduchem pomoci orgánu 1£ pro zpétný pro plaoh ,který je z hlediska sméru zpétného proplaohování uspoŕádán pred sítem 13. a se dobtat potrubím 8 pro vynááení kalu k dalšímu z hodnocení.Na konci pochodu zpétného proplaohování se kulový kohout 2 opôt zavŕe.Upon completion of free flushing, the ball valve 2 closes. By opening the ball valve 23, the dry sludge can be purged with air by the backflushing body 16 which is arranged in front of the screen 13 in terms of the backflushing direction and can be taken through the sludge discharge line 8 for further evaluation. the ball valve closes 2 spindles.

ľŕi alternativním pochodu k pŕedcházející formé provedení je kulový kohout 1 otevŕen tak dlouho ,dokud z komory 10 nedospeje pŕes sensor 11 ke kulovému kohoutuIn an alternative process to the preceding embodiment, the ball valve 1 is opened until the sensor 10 reaches the ball valve from the chamber 10 via the sensor 11.

-b1 signál, který tento pfiméje k tomu,aby na základé dosadení mezního naložení komory 10 kalem , komoru 10 až k dokončení pochodu odkalování uzavrel, lo té eo se kulový kohout 1 zavrel, odehraje se pochod odkalování vylíčený u p?edchozího pííkladu provedení, píl zachovaní plné schopnosti filtrace.-b1 a signal which causes it to close the chamber 10 to completion of the sludge deposition until the sludge removal process is complete, after the ball valve 1 has been closed, the sludge process depicted in the preceding embodiment, sawing maintaining full filtration capability.
