Description
技术领域technical field
本实用新型涉及灭火装置领域，尤其涉及一种基于涡流管制冷的气溶胶灭火装置。The utility model relates to the field of fire extinguishing devices, in particular to an aerosol fire extinguishing device based on vortex tube refrigeration.
背景技术Background technique
气溶胶灭火器作为重要灭火设备而具有广阔市场前景，在消防灭火领域应用广泛，已被广泛应用到移动通信、电力、石化、军事和民用各个消防领域。其中的气溶胶灭火剂属于烟火类药剂，当灭火剂生成气溶胶，喷出的气溶胶温度很高，会对被保护空间形成二次危害，因此灭火装置喷放时需在灭火装置中进行降温处理，目前市场上的灭火装置存在以下缺点：降温效果不理想，制造成本高；气溶胶出口温度过低，固体微粒会凝聚，微粒变大，弥散性变差，从而降低灭火效能，甚至不能扑灭、遮挡火；化学降温材料反应不充分，造成降温材料浪费，并且受热分解出一些有害气体，造成环境污染；有些物理或化学降温材料的硬度低，在运输过程受振动破碎，造成阻塞灭火出口，导致喷射过程不平稳、不安全。As an important fire extinguishing equipment, aerosol fire extinguishers have broad market prospects and are widely used in the field of fire extinguishing. They have been widely used in mobile communications, electric power, petrochemical, military and civilian fire fighting fields. Among them, the aerosol fire extinguishing agent belongs to the pyrotechnic agent. When the fire extinguishing agent generates aerosol, the temperature of the sprayed aerosol is very high, which will cause secondary damage to the protected space. Therefore, the fire extinguishing device needs to be cooled in the fire extinguishing device when spraying. However, the fire extinguishing devices currently on the market have the following disadvantages: the cooling effect is not ideal, and the manufacturing cost is high; if the outlet temperature of the aerosol is too low, the solid particles will condense, the particles will become larger, and the dispersibility will become poor, thereby reducing the fire extinguishing efficiency and even failing to extinguish the fire. , block fire; chemical cooling materials react insufficiently, resulting in waste of cooling materials, and some harmful gases are decomposed by heat, causing environmental pollution; Cause the spraying process to be unstable and unsafe.
现有的涡流管制冷技术是压缩空气制冷技术的一种。涡流管又可称之为涡漩管或旋风管，是一种结构简单的能量分离装置。当压缩气体进入涡流管时，会同时产生焦汤效应和希尔茨效应，这两种效应的叠加便产生了“冷”、“热”气分离效果。涡流管一端喷射冷空气，另一端喷射热空气。The existing vortex tube refrigeration technology is a kind of compressed air refrigeration technology. A vortex tube, also called a vortex tube or a cyclone tube, is an energy separation device with a simple structure. When the compressed gas enters the vortex tube, it will produce scorching soup effect and Shirtz effect at the same time, and the superposition of these two effects will produce the separation effect of "cold" and "hot" gas. The vortex tube injects cool air from one end and hot air from the other.

The vortex tube 4 includes a vortex chamber 6 and a high-pressure gas inlet pipe 7 communicated with the vortex chamber 6, a hot gas pipe 8 and The cold air pipe 9, wherein the cold air pipe 9 and the hot air pipe 8 are located at the left and right sides of the vortex chamber 6 respectively, the high-pressure gas inlet pipe 7 at the upper end of the vortex chamber 6 is connected with the high-pressure gas source 5, and a pipeline valve 11 is arranged at the high-pressure gas inlet pipe 7, and the cold air Air pipe 9 passes through partition 10, cold air outlet 13 is located in the first working room, hot air pipe 8 passes through casing 1, and its hot air outlet 12 is located above casing 1 side outside.

The farther the gas is from the pipe wall, that is, the closer to the separation pore 15, the smaller the kinetic energy of the gas and the lower the temperature; on the contrary, the farther away from the separation pore 15, the higher the temperature of the gas. Due to the negative pressure in the tube, the low-temperature gas passes through the separation hole 15 and enters the other side of the vortex chamber partition 14, that is, the cold air pipe 9. The outlet of the cold air pipe is located at the upper part of the first working chamber 16.
