Abstract

Method for analysing a gas mixture containing a dusty solid (8) by separating a defined amount (2) of the gas mixture and passing this on to analysis via a sampling duct (4), the separated gas mixture, in order to absorb it into a liquid, being admixed with a known amount of liquid and analysis being carried out by analysing the liquid and the gas mixture absorbed thereby. The liquid (5) is admixed to the separated gas mixture to be passed on to analysis immediately after the gas has been separated, and the separated gas mixture, together with the liquid, is passed to analysis via a sampling duct (4). <IMAGE>

Description

Изобретение относитс  к способу подготовки и анализа газовой пробы, котора  может содержать пылеобразное твердое вещество.This invention relates to a method for preparing and analyzing a gas sample, which may contain a dusty solid.

Цель изобретени  - повышение качества отделенной пробы и осуществление непрерывного качественного и количественного анализа, а также определение концентрации глауберовой соли в дымовых газах от бойлера-утилизатора .The purpose of the invention is to improve the quality of the separated sample and to carry out continuous qualitative and quantitative analysis, as well as to determine the concentration of glauber salt in the flue gases from the recovery boiler.

На чертеже изображено схематично устройство дл  осуществлени  способа.The drawing shows schematically a device for implementing the method.

Способ осуществл етс  следующим образом.The method is carried out as follows.

Газова  проба всасываетс  с определенной скоростью через конкретный пробоотборный трубопровод 1. Внутренн   поверхность зонда промываетс  при непрерывном впрыскивании воды, вода направл етс  через трубку 2 к пробо- отборному концу пробоотборного трубопровода 1 дл  того, чтобы промытьThe gas sample is sucked at a certain rate through a specific sampling pipe 1. The inner surface of the probe is rinsed with continuous water injection, the water is directed through tube 2 to the sampling end of the sampling pipe 1 to flush

внутреннюю поверхность зонда точно отмеренным количеством воды, котора  после этого направл етс  вдоль трубы 3 к разделительному устройству 4, где твердые частицы, не растворимые в воде, отдел ютс  от вод ного потока, который направл етс  в следующее разделительное устройство 5, в нем газы отдел ютс  от вод ного потока и откачиваютс  при помощи компрессора 6. вод ной поток направл етс  в измерительную  чейку 7s в которой непрерывно измер етс  концентраци  ионов натри  при помощи чувствительного к ионам натри  электрода. Концентраци  ионов натри  в виде электродного потенциала показываетс  с помощью графо- построительного устройства. На осш - ве объема отобранного газа, объема промывного раствора и измеренной концентрации ионов натри  можно расе чч тать концентрацию пауберовой сс- ч i, дымовом газе в каждый конкретней мс мент.the inner surface of the probe with exactly measured amount of water, which then goes along the pipe 3 to the separation device 4, where the solid particles, insoluble in water, are separated from the water flow, which is sent to the next separation device 5, in it the gases separate From the water flow and pumped out by means of the compressor 6. The water flow is directed to the measuring cell 7s in which the concentration of sodium ions is continuously measured by means of a sodium-sensitive electrode. The concentration of sodium ions in the form of an electrode potential is indicated by a plotting device. On the basis of the volume of the selected gas, the volume of the leaching solution, and the measured concentration of sodium ions, the concentration of the Pauberian gas i, the flue gas in each specific moment can be dispersed.
