Description

Portable gas preprocessor interlocking with a user terminal at a spaced location

The present invention relates to a gas preprocessor, and more particularly, to a portable gas preprocessor that works with a user terminal at a spaced apart location.

Various combustion facilities such as power generation boilers and incineration boilers are operated at workplaces that use fossil fuels, incineration plants that incinerate industrial waste or general household waste, and the combustion in these facilities adversely affects the human body and the natural environment. Emissions containing various types of harmful substances can be caused.

For this reason, in the case of workplaces such as thermal power plants and steel mills or incinerators, the amount of hazardous substances emitted is regulated by law worldwide, and the amount of harmful substances contained in exhaust gas is also limited in Korea. In order to inspect whether or not the standards according to this are satisfied, the workplace concerned is taking a sample of the gas discharged from the chimney and measuring and analyzing the harmful substances contained in the exhaust gas through various “measurement” and analysis devices.

Before proceeding with the measurement of the exhaust gas, 　pre-processing　work to control the temperature of the sample gas and remove moisture and dust contained in the sample gas must be performed for the accuracy of the measured value.

The gas preprocessing device that performs the pretreatment operation only detects only the gas from which elements that interfere with measurement and analysis, such as moisture and dust, are removed to a certain level from among the discharged “gases”, for example, through a tele-monitoring system (TMS). It is supplied as an applied chimney automatic gas measuring device (Clean SYS). In addition to the most widely used chimney automatic gas measuring device (Clean SYS), it is also used in acid treatment facilities at steel mills, incinerator melting furnaces, pretreatment facilities, and laboratories to enable intermittent measurement. Its application field is wide.

In general, gas pretreatment devices are often manufactured in an installation type that is firmly installed on a wall surface. Therefore, the location where the pretreatment work is performed is inevitably limited, and even if a portable gas meter is used, the sample must be transported to the place where the gas pretreatment device is located before measurement to perform the pretreatment work, making it difficult to measure the exhaust gas immediately on site. In addition, the installation and maintenance costs of the gas preprocessing device manufactured in the installation type are inevitably high due to its volume and installation difficulty.
