Abstract
A gas sensing device is provided. The gas sensing device includes a transparent box having an inner space, a gas adsorption filter disposed on a first surface of the transparent box and in contact with the inner space, and a gas indicator disposed in the inner space.
Description
The present invention relates to a gas sensing device.
Recently, accidents involving the leakage of harmful gas from chemical plants have been occurring continuously. A gas leak accident may leak a large amount of gas from the beginning, but in the early stage, a small amount of gas starts to leak and often leads to a serious accident. In this way, it is not easy to detect gas because a small amount of gas leaks in the beginning. In addition, it is possible to prevent accidents from spreading when the gas is leaked in the early stage, and to minimize the damage of human life.
In order to solve the above problems, the present invention provides a gas sensing device capable of sensing a gas leaked into the atmosphere.
Other objects of the present invention will become apparent from the following detailed description and the accompanying drawings.
A gas sensing device according to embodiments of the present invention includes a transparent box having an inner space, a gas adsorption filter disposed on a first surface of the transparent box and in contact with the inner space, and a gas indicator disposed in the inner space do.
The gas indicator in the interior space can be seen through the transparent box.
The gas outside the transparent box moves to the internal space through the gas adsorption filter, and the gas indicator may react with the gas to change color.
The gas absorption filter may include a first gas adsorption filter in contact with the first inner space and a second gas absorption filter in contact with the second inner space and the second inner space, An adsorption filter, and the gas indicator may include a first gas indicator disposed in the first inner space and a second gas indicator disposed in the second inner space.
The first gas adsorption filter and the second adsorption filter may be different from each other, and the first gas indicator and the second gas indicator may be different from each other.
The inner space may include a first inner space, a second inner space, a third inner space, and a fourth inner space which are isolated from each other. The gas adsorption filter may include a carbon dioxide gas adsorption filter contacting the first inner space, A propane-based gas adsorption filter including a methane-based gas adsorption filter in contact with the second internal space and in contact with the third internal space, and a biogas adsorption filter in contact with the fourth internal space, A carbon dioxide gas indicator disposed in the first internal space, a methane-based gas indicator disposed in the second internal space, a propane-based gas indicator disposed in the third internal space, and a biogas Indicator may be included.
The gas sensing device may further include an opening / closing part disposed on a second surface of the transparent box and opening / closing the inner space.
The gas sensing device may further include an adsorbent powder disposed in the inner space.
According to embodiments of the present invention, gas leaked into the atmosphere can be detected simply and effectively. The leaked gas can be detected even when the concentration of the leaked gas is low. It can detect not only one kind of gas but also more than two kind of gas.
