The present invention discloses a system installed around a penetration hole of a pipe penetrating wall structure which divides a certain space and sealing the penetration hole in case of fire, which comprises a housing unit, a connecting unit and a fixing unit. A housing unit forming a body and having a predetermined accommodatable space, a connecting unit connected to the housing unit, interconnecting the housing unit in a series and a fixing unit arranged at a side of the housing unit, fixing the housing unit to the wall structure.

Chained fireproof sealing system

The present invention discloses a fire-resistant sealing unit installed adjacent to a penetration part penetrating a partition wall inside a building, and filling the penetration part with fire-resistant sealing by heat generated in case of a fire in the building; a fire sensing unit installed adjacent to a fire-resistant sealing unit to detect whether a fire has occurred in a compartment area; and a control server that divides the inside of the building into predetermined conceptualized compartments, manages them as conceptualized compartmental areas, detects fire occurrence information from a fire sensing unit for each compartmental area, and calculates fire vector information.

Building monitoring system for sensing fire on every fire compartment in real time by using sensor attached to edge of hole of fire wall

The present invention relates to a method for continuous removal of carbon dioxide, the method comprising the steps of: a) preparing an aqueous solution containing an amine-based compound and an acidic calcium compound; b) bringing a gas containing carbon dioxide to be treated into contact with the aqueous solution to prepare a calcium carbonate precipitate; and c) recovering the calcium carbonate and then adding a basic calcium compound to the residual aqueous solution, wherein after step c), step b) and step c) are repeatedly performed. The removal of carbon dioxide by the method of the present invention has advantages of requiring low energy and being capable of mineralizing and removing carbon dioxide at a fast rate without a separate time for induction.

Method and apparatus for continuous removal of carbon dioxide

The present invention relates to an apparatus and method of preparing carbonate and/or formate from carbon dioxide. The apparatus of preparing carbonate and/or formate from carbon dioxide (CO), comprising: an electrolysis reactor comprising (i) an anode which contains an aqueous solution of a Group I metal salt as an electrolytic solution, (ii) an ion-exchange membrane through which metal cations derived from the Group I metal salt and water flow from an anode to a cathode, (iii) a cathode, and (iv) a gas diffusion layer which supplies a carbon dioxide-containing gas to the cathode; a power supply unit of applying a voltage between the anode and the cathode; a first gas-liquid separator of recovering the electrolytic solution from the products formed in the anode; a second gas-liquid separator of recovering carbonate and/or formate from the products formed in the cathode; a pH meter of measuring the pH of the electrolytic solution recovered from the first gas-liquid separator; a first reactant supply unit of supplying (a) the electrolytic solution recovered from the first gas-liquid separator and (b) the aqueous solution of the Group I metal salt with which the recovered electrolytic solution is replenished according to the pH of the electrolytic solution, to the anode; and a second reactant supply unit of supplying carbon dioxide or a mixer comprising carbon dioxide and water vapor to the cathode; wherein, when a voltage is applied between the anode and the cathode, in the anode, water undergoes electrolysis to generate hydrogen ions, oxygen, and electrons, and metal cations in the Group I metal salt are substituted with the hydrogen ions, while the generated metal cations move to the cathode through the ion-exchange membrane and the electrons move to the cathode through an external electric line; and in the cathode, carbon dioxide, water, metal cations, and electrons are reacted and produce carbonate and/or formate.

Apparatus and method of preparing carbonate and/or formate from carbon dioxide

The present invention relates to a method and an apparatus of preparing a reduction product of carbon dioxide by electrochemically reducing carbon dioxide. The present invention can prepare, in an energy-efficient manner, a reduction product of high-concentration carbon dioxide with high Faraday efficiency as in a liquid reduction reaction by producing the reduction product of carbon dioxide by supplying water or an electrolytic solution to an anode region; supplying humidified carbon dioxide gas having a second temperature higher than a first temperature to a cathode region within an electrochemical cell having the first temperature so as to supply the carbon dioxide gas which has been humidified to be in a condition where the relative humidity is greater than 100%, while applying a voltage between the anode region and the cathode region so as to generate hydrogen ions (H) in the anode region; and transporting the hydrogen ions to the cathode region through the electrolyte membrane, thereby electrochemically reducing the carbon dioxide gas.
