The present invention relates to an air dilution type exhaust gas continuous collection device, in particular, when collecting the exhaust gas to analyze the specific components contained in the exhaust gas containing a large amount of water in the exhaust gas collected by diluting the exhaust gas by simultaneously injecting a large amount of dry air The present invention relates to an air dilution flue gas continuous collecting device capable of lowering the partial pressure of moisture to prevent condensation of moisture and stably collecting flue gas continuously.

In general, in order to continuously measure the components contained in the flue gas, equipment for collecting the flue gas continuously is installed at the discharge port, and the continuously collected flue gas is transferred to the analyzer through a pipe and analyzed.

However, if there is a large amount of moisture in the flue gas, the water is condensed during the transfer process and the pipe is closed or if the specific component to be measured has a high solubility in water, it is impossible to measure accurately because it is dissolved in the water condensed in the pipe.

Therefore, in order to prevent the condensation of water, the method of heating the pipe to which the exhaust gas is transported is most commonly used, but even in this case, when there is a large amount of water, there is a limit to completely prevent the condensation of water.

The present invention solves the above-mentioned problems and can collect the exhaust gas continuously while preventing the problem caused by water condensation in advance, thereby providing an air dilution type exhaust gas continuous capture device that can improve the reliability of the analysis value. There is a purpose.

In order to achieve the above object, the present invention has a left end sealed, a wire mesh is installed on the right end, a main body having a sealing lid formed on the middle portion, and a standard gas embedded through the right end and the sealing lid of the main body. A sample gas supply pipe is connected to the vacuum gauge connecting pipe at the left end, connected to the left end of the main body while penetrating the supply pipe and the sealing lid, and an orifice and a filter are provided at the right end, and dilution air is supplied to the reduction pipe. A pipe is connected, the sample gas supply pipe is installed on the Venturi Throttle (Venturi Throttle), provides an air dilution exhaust gas continuous collection device characterized in that consisting of a venturi connected to the sample pipe diluted in the expansion pipe do.

Hereinafter, the structure and operation of the air dilution exhaust gas continuous collection device according to the present invention will be described with reference to FIG.

After the air supplied from the compressor or the bomb is purified through the water removal trap and the filter, the air is supplied at a constant pressure through the dilution air supply pipe (1) installed through the left side of the main body (11), which is a circular pipe. Venturi Throttle (Venturi Throttle), passing through the venturi (3) consisting of a magnification tube is a vacuum to the rear end of the reduction tube at this time.

At this time, the left end of the sample gas supply pipe 20 is connected to the upper part of the Venturi Throttle of the Venturi 3, and the vacuum phenomenon of the Venturi Throttle does not require additional power. Flue gas at the outlet is sucked in.

Here, the exhaust gas of the outlet port passes through the filter 9 and the orifice 8 of the lamella wool, which is addressed to the right end of the sample gas supply pipe 2 via the wire mesh 10 installed at the right end of the main body 11. do.

In addition, the exhaust gas is supplied to the upper part of the Venturi Throttle of the Venturi 3 through the sample gas supply pipe 2, mixed with the air for dilution, and then diluted with the sample tube connected to the expansion tube of the Venturi ( 4) flows into the analyzer external to the left side of the main body 11 and the components in the exhaust gas are analyzed.

At this time, the dilution ratio is higher as the dilution air pressure (flow rate) and the size of the orifice 8 installed at the right end of the sample gas supply pipe 2 are higher, and the dilution ratio is higher and connected to the venturi throttle to confirm that the exhaust gas is stably sucked. Connect the vacuum gauge connecting pipe (5) to the sample gas supply pipe (2) to check the degree of vacuum.

On the other hand, a separate analyzer is required to analyze the composition of the flue gas, and the analyzer must be calibrated using standard gas periodically to check and calibrate the analyzer's performance.

Therefore, when the standard gas starts to be supplied through the standard gas supply pipe 6 which is embedded through the left side of the main body 11 when the analyzer is calibrated, the orifice 8 is raised between the sealing lid 7 and the wire mesh 10. The air in the space is excluded from the outside, and after a certain time, the space is filled with standard gas.

The standard gas filled in the empty space is mixed with air for dilution through the sample gas supply pipe 2 through the orifice 8 and then supplied to the analyzer through the diluted sample pipe 4.

In addition, since the flue gas continuously collected by the air dilution flue gas continuous capture device is mixed with the dilution air and a constant ratio, the concentration of the analyzed specific component should be corrected by the dilution ratio, and the dilution is measured to be lower than the actual concentration of the specific component. By multiplying the dilution ratio, it is possible to simply obtain the actual concentration.

The present invention can continuously collect the exhaust gas while preventing problems due to moisture condensation, thereby providing an effect of improving the reliability of the analysis value.
