7 results about "Flammable liquid" patented technology

A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosive agents, pesticides, or combustible waste. The safety cabinet includes a heat-actuated damper including a body, a valve plate, and a pivot assembly. The valve plate is disposed within a passageway of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to limit movement of the valve plate from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature, thereby allowing the biasing system to move the valve plate to the closed position.

This invention relates to a system and method for testing the atomization and ignition of flammable liquids upon impact with a hot surface, belonging to the field of combustion characteristic testing technology. It overcomes the limitations of existing testing equipment in exploring critical atomization conditions and the impact of atomization degree on combustion efficiency, while also solving the problem of difficult visualization of combustion flames. The solution is as follows: the testing system includes a droplet generation component for generating single droplets with controllable particle size, and a droplet atomization and ignition component for atomization upon impact with a hot surface and subsequent ignition. The droplet generation component includes an injection pump, an adapter valve, and a coaxial needle. The droplet atomization and ignition component includes a base, a guide rod, a clamping arm, and a pneumatic ignition component. The control system is electrically connected via data cables to a control switch, injection pump, heating controller, high-speed camera, and computer at the gas cylinder outlet. Data collected using the testing system and method provided by this invention provides a basis for studying droplet atomization characteristics and combustion mechanisms.

A firefighting foam concentrate that is free or substantially free of fluorosurfactants is disclosed. The firefighting foam concentrate comprises water and from 25% to 38% by weight of a surfactant blend comprising at least one selected cationic quaternary ammonium compound, at least one selected alkyl amine oxide nonionic surfactant, and at least one selected alkyl sulfate anionic surfactant. Each selected surfactant has an average alkyl or alkylene carbon chain length of 8-10 carbon atoms. The firefighting foam concentrate may be combined with other firefighting foam components to form a firefighting foam composition. Also disclosed is a method of fighting a fire comprising aerating the firefighting foam composition containing the surfactant blend to form a firefighting foam that is applied to a fire or the surface of a volatile flammable liquid.

The application discloses an engine fuel collection system and a gas-liquid separation device, and belongs to the technical field of marine engines. The engine fuel collection system comprises a cylinder body, a indicator valve, a shell and an air inlet pipe, the air inlet end of the air inlet pipe is communicated with the indicator valve, a first impeller and a second impeller are rotatably arranged in a collection cavity, the first impeller is used for guiding at least part of medium from an air outlet end to flow towards an inner circumferential wall of the shell, the second impeller is used for guiding the medium guided through the first impeller to flow towards an inner bottom wall of the shell, a cover plate and an air outlet pipe. The first impeller and the second impeller are arranged to guide the flow of the gas-liquid mixture sprayed from the indicator valve, so that the gas-liquid mixture rubs and collides with the remaining structure in the process, thereby gradually increasing the size of the liquid droplets and falling under the action of gravity, realizing gas-liquid separation. The gas is discharged through the air outlet pipe, the toxic or flammable liquid in the form of gas mist is prevented from entering the cabin environment, and the risk of forming an explosive mixture is reduced.
