Embodiment Construction

[0038] Hereinafter, a filter device according to an embodiment of the present invention and a gas analysis system having a filtration device will be described with reference to the accompanying drawings.

[0039] The gas analysis system is, for example, a system of the harmful ingredient (two dioxide, mercury, etc.) contained in the exhaust gas (coal dust gas) produced in the equipment such as the incinerator using a gas analyzer. The exhaust gas is sampled directly from the catheter flow of exhaust gas. The gas analysis system includes a filtration device that removes the coal dust included in the exhaust gas of the gas analyzer.

[0040] like figure 1 As shown, the gas analysis system 50 of the present embodiment includes an injection port 52 disposed in the exhaust gas Eg flow, and the filter device 1 and the analysis of the coal dust from the exhaust gas EG taken in the incident port 52 are removed by filtration device 1. Gas analyzer 53 of coal dust EG.

[0041] The exhaust g...

Abstract

The filtering device (1) has: a filtering part (2), a gas inlet (3) for introducing coal dust-containing gas (EG), a gas outlet (4) for directly discharging coal dust-containing gas (EG), A part of (5) discharges the first discharge port (6) of the coal dust-containing gas (EG) and the second discharge port (7) of the coal dust-containing gas (EG) through the other part of the filter (5); and controls The device (12) controls the opening and closing of the first valve (9) for opening and closing the first discharge port (6) and the second valve (10) for opening and closing the second discharge port (7). Under predetermined conditions, the control device (12) closes the first valve (9) and opens the second valve (10).

Description

Technical field [0001] The present invention relates to a filtration device and a gas analysis system. [0002] The present application claims priority to Japanese Patent Application No. 2018-025180, based on February 15, 2018, and is used herein. Background technique [0003] The exhaust gas produced in the incinerator or the like contains harmful ingredients (two malt, mercury, etc.). Therefore, it is known that there is a technique of continuously analyzing the content of the hazardous substance from the catheter and controlling the combustion of the furnace according to the analysis results. [0004] Patent Document 1 discloses the following technique, i.e., as far as possible in the upstream analysis of the mercury concentration in the exhaust gas, when the concentration is greater than a predetermined value, the concentration is reduced, so as not to discharge the exhaust gas in a state in which the mercury concentration is high. [0005] In this technique, the exhaust gas ...
