Title (EN) EXHAUST GAS TREATMENT METHOD AND EXHAUST GAS TREATMENT DEVICE

Abstract:
(EN) [Problem] To increase elimination efficiency for acidic gases included in exhaust gas as much as possible while suppressing costs as much as possible in an exhaust gas treatment method wherein a precoated layer is formed on filter cloth for a filter type dust collection device 3 by using a chemical agent that neutralizes exhaust gas. [Solution] The exhaust gas treatment method performs: precoating treatment for forming the precoated layer on the filter cloth for the filter type dust collection device 3 by using unpulverized sodium bicarbonate as the chemical agent for neutralizing acidic gas in exhaust gas; and, during exhaust gas treatment, monitoring treatment for examining whether or not the precoating treatment is to be carried out. Thus, for example, a facility for fine grinding of the sodium bicarbonate becomes unnecessary, and the necessity of adding an anticaking agent also disappears.
(FR) Le problème décrit par la présente invention est d'augmenter le rendement d'élimination de gaz acides inclus dans les gaz d'échappement dans la mesure du possible tout en supprimant les coûts au maximum dans un procédé de traitement de gaz d'échappement, une précouche étant formée sur le tissu filtrant d'un dispositif de collecte de poussière de type filtre 3 à l'aide d'un agent chimique neutralisant le gaz d'échappement. Selon l'invention, la solution comporte un procédé de traitement de gaz d'échappement qui réalise : un traitement pour former la précouche sur le tissu filtrant du dispositif de collecte de poussière de type filtre 3 en utilisant du bicarbonate de sodium non pulvérisé en tant qu'agent chimique pour neutraliser un gaz acide dans un gaz d'échappement; et, pendant le traitement des gaz d'échappement, un traitement de surveillance pour examiner si le traitement pour former la précouche doit être ou non effectué. Par exemple, une installation pour le broyage fin du bicarbonate de sodium devient inutile, et la nécessité d'ajouter un agent anti-agglomérant disparaît également.
(JA) 【課題】ろ過式集塵装置3のろ布に、排ガスを中和するための薬剤でプレコート層を形成する排ガス処理方法において、コストを可及的に抑制しながら、排ガスに含まれる酸性ガスの除去効率を可及的に高める。 【解決手段】排ガス処理方法は、ろ過式集塵装置3のろ布に、排ガス中の酸性ガスを中和するための薬剤として未粉砕の重曹を用いてプレコート層を形成するプレコート処理と、排ガス処理中に、前記プレコート処理を実行させるか否かを調べる監視処理と、を行う。これにより、例えば重曹を微粉砕するための設備が不要になるとともに、固結防止剤を添加する必要が無くなる。
