Description

Die Erfindtuig betrifft ein SchIatelektro- filter zur Entstaubung der heißen Abgase von Br:nnsto:fitrocl-znern. itisb°_sondere Scliivebetroclaieranlagen z_. B. für Braunlc4- rille. Der Erfindung liegt die Aufgabe zugrunde, die Abgase und ihren @-ärmeünhalt nach der Entstaubung für den Betrieb der Trockinr- anlag:e nutzbar zu inach°ti. Zu diesem Zweck ist der Erfindung gemäß der von unten nach oben vo.n dem zu reinig-Inden Gas durch- strömte Elektrofilterschacht mit einem Banal versehen, der von der Reingasseite aus durch den E1Ektrodeneinbau hindurch nach abwärts verlatifand von dein heißen noch in der Reini- gung begriffenen Gas umspült wird und einen Teil des Beingases in die Troclzneranlagz zurückführt. In \-erl>iiidtuig hiermit ist der Reingasauslaß des Elektro:filterschachtes über dem Elektrodeneinbau durch einen geg°nüber dein Schacht ini Ouerschnitt verengten Schornsteinaufsatz vü7Iängert, der den Ab- stand zwischen der ins Freie mündenden Aus- trittsst21le des Pein'as°s aus dein Schacht und der Eititrittsst°II- in den Rückführungs- kanal vergrößert. Durch diese Abstands- und «uerschnittsveretigung wird dtil! 1)zini Einsaugen des Reingastcilstronies in den beheizten Rück- fiihrtuig:kanal kalte Aull#2nItift am Sclilt>.tl,,3pf mitang:saugt und durch TPinl>erattirseiilcung der durch den Rückfü hrtnigskanal erstrebte Zweck der Ai-;wärmevirwertung in Frage gesteht wird. Bei Elektrofiltern ist es b:kannt. voll dein gereinigten Gas ein:ti TeiIstroni abzuzweigen und dein Rolig'as zwecks Kühlung wieder zuzuführen. Im Ge gensatz Hierzu handelt es sich bei der Erfindung uni die Entnahme eines heißen Reingast".'1lstromes zum G,%veili der Wärmeverwertung in einer Brennsttifitr=->cl:- neranlage. In der Zeichtiun;-- ist an :mein Beispiel veranschaulicht, wie die Erfindung ausgeführt werden kann. Abh. i ist ein Längsschnitt nach _I-P, der Abb. 2 und Abb.2 ein T_iftigscliiiitt nach C-D der Abb. z.

Der be- heizteRaum 1a innerhalb der Stützen io steht (huch. eine Rohrverlängerung 13 mit de111 Reingasraum des Schachtes 3 in Verbindung. Zwischen den Elelztrofiltergruppeti 1. 2 und von ihnen beheizt, verläuft ein senkrechter Kanal i.i, der oben an den 1Zeiilgasrauin des Schaftes 3 anschließt und unten finit einem Exhaustor 1ä verbunden ist. der den ab- gesaugten Teil des Rein gases @ler Trockner- anlage zuführt. The invention relates to a SchIatelektro- filter for dedusting hot exhaust gases by Br: nnsto: fitrocl-znern. itisb ° _s special Scliivebetroclaieranlagen z_. B. for Braunlc4- groove. The invention is based on the object the exhaust gases and their @ -arm content after the Dedusting for the operation of the drying Appendix: e can be used at inach ° ti. To this end is the invention according to the from below at the top of the gas to be cleaned streamed electrostatic filter shaft with a banal provided that from the clean gas side through down through the E1 electrode installation lost from your hot still in the clean the gas being flushed around and one Part of the leg gas into the dryer system returns.
