Description
技术领域technical field
本发明涉及一种高温高压流体洁净系统，属于流体力学、气体动力学、机械结构设计及医药卫生、化工、水处理、饮料、气体净化等多种领域。The invention relates to a high-temperature and high-pressure fluid cleaning system, which belongs to various fields such as fluid mechanics, gas dynamics, mechanical structure design, medicine and hygiene, chemical industry, water treatment, beverage, and gas purification.
背景技术Background technique
气体洁净技术本来是一个古老的课题，由工矿企业(如金属冶炼、纺织、水处理等领域)需要对生产环境进行工业通风和气体净化而发展起来。经过近百年的发展，从理论和工程实践应用来看，各种通风除尘和液体洁净技术已经比较成熟，国内外已发表的相关方面的文献不下10000篇。但随着军工产品开发和研究的快速开展，尤其是光电精确制导武器系统、激光武器系统的快速发展对风洞实验环境提出了更高的要求，这些模型的风洞试验不仅要求流场品质和流动参数满足气动力/热测量的需求，还要求来流气体的洁净度能够模拟飞行试验条件，消除污染气体对光测成像技术和气体比热比的影响。这样传统的工业通风和气体洁净技术就存在很大的局限性，已经不能适应风洞试验的需求。如工业通风常用的旋风除尘器，在常温常压条件(285K，1atm)下可以获得92.5％以上的除尘效率。但随着来流静压和温度的提高，除尘效率明显下降，而为降低旋风除尘器表面温度而附加的保温材料又会导致设备体积更加庞大，使风洞有限的防爆空间更加狭窄，极大的增加了安全隐患；很多时候由于风洞空间限制甚至无法安装合适的除尘器。再如工业和民用常用的静电除尘器，除尘效率也非常高(97％以上的除尘效率)，净化效果也很好，可以过滤1um以下的粉尘，但这一设备只能净化很小的气体流量，而且在高温高压环境中，由于高温辐射和高位势能的影响，除尘效率并不是很好。本发明采用新型的先进的过滤技术，并将其应用于高温高压大流量环境中，开发和拓展了目前这一新型技术---高温高压流体洁净系统。这一技术的最大优点是可以应用于1200K的高温和170atm的高压环境；气体来流流量可以调节，可以满足国内风洞试验所要求的各种流量条件。Gas cleaning technology is an old subject originally, which was developed by industrial and mining enterprises (such as metal smelting, textile, water treatment, etc.) that need industrial ventilation and gas purification for the production environment. After nearly a hundred years of development, from the perspective of theory and engineering practice, various ventilation and dust removal and liquid cleaning technologies have been relatively mature, and there are no less than 10,000 related literatures published at home and abroad. However, with the rapid development of military product development and research, especially the rapid development of photoelectric precision guided weapon systems and laser weapon systems, higher requirements are placed on the wind tunnel experiment environment. The wind tunnel tests of these models not only require the flow field quality and The flow parameters meet the requirements of aerodynamic/thermal measurement, and the cleanliness of the incoming gas is required to simulate the flight test conditions, eliminating the influence of polluted gas on optical imaging technology and gas specific heat ratio. In this way, the traditional industrial ventilation and gas cleaning technology has great limitations, and can no longer meet the needs of wind tunnel tests. For example, the cyclone dust collector commonly used in industrial ventilation can obtain a dust removal efficiency of more than 92.5% under normal temperature and pressure conditions (285K, 1atm). However, with the increase of incoming static pressure and temperature, the dust removal efficiency drops significantly, and the additional insulation material to reduce the surface temperature of the cyclone dust collector will lead to a larger equipment volume, making the limited explosion-proof space of the wind tunnel narrower, which greatly Increased potential safety hazards; in many cases, it is even impossible to install a suitable dust collector due to the space limitation of the wind tunnel. Another example is the electrostatic precipitator commonly used in industry and civil use. The dust removal efficiency is also very high (over 97% dust removal efficiency), and the purification effect is also very good. It can filter dust below 1um, but this equipment can only purify a small gas flow. , and in a high temperature and high pressure environment, due to the influence of high temperature radiation and high potential energy, the dust removal efficiency is not very good. The present invention adopts a new type of advanced filtering technology, and applies it to the environment of high temperature, high pressure and large flow, and develops and expands the current new technology---high temperature and high pressure fluid cleaning system. The biggest advantage of this technology is that it can be applied in a high temperature environment of 1200K and a high pressure environment of 170atm; the gas flow rate can be adjusted to meet various flow conditions required by domestic wind tunnel tests.
