一种静音的污染物气体暴露舱尾气发生装置A silent pollutant gas exposure cabin exhaust gas generating device

技术领域technical field

本发明涉及实验设备技术领域，特别是涉及一种静音的污染物气体暴露舱尾气发生装置。The invention relates to the technical field of experimental equipment, in particular to a silent exhaust gas generating device of a pollutant gas exposure chamber.

背景技术Background technique

随着我国近代工业化及城镇化进程加速，空气污染问题日益严重，其中机动车尾气排放是主要污染物来源之一。截至2021年底，公安部交管局发布全国机动车保有量达3.95亿辆。随着机动车数量急速增加，交通相关空气污染(Traffic－related airpollution，TRAP)问题日益突出。TRAP的主要污染物种类包括颗粒物(PM)、挥发性有机物(VOCs：烷烃类)、多环芳烃类(PAHs)、一氧化碳(CO)、氮氧化物(NOx)、硫氧化合物(SOx)、碳氢化合物(HC)、重金属离子等。2021年9月，世界卫生组织的最新评估称，每年约有700万人死于与空气污染有关的疾病，如慢性呼吸道疾病、卒中、心血管病、肺癌和其他癌症等。With the acceleration of modern industrialization and urbanization in my country, the problem of air pollution is becoming more and more serious, and the exhaust emission of motor vehicles is one of the main sources of pollutants. By the end of 2021, the Traffic Management Bureau of the Ministry of Public Security announced that the national motor vehicle ownership reached 395 million. With the rapid increase in the number of motor vehicles, the problem of traffic-related air pollution (TRAP) has become increasingly prominent. The main pollutant types of TRAP include particulate matter (PM), volatile organic compounds (VOCs: alkanes), polycyclic aromatic hydrocarbons (PAHs), carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), carbon Hydrogen compounds (HC), heavy metal ions, etc. In September 2021, the World Health Organization's latest assessment said that about 7 million people die each year from air pollution-related diseases such as chronic respiratory disease, stroke, cardiovascular disease, lung cancer and other cancers.

人体呼吸系统是机体防御外界有害物质的第一道屏障，受到的损伤首当其冲。机动车尾气中的颗粒物尤其精细颗粒物及其附着物等能被人体吸入小气道进入肺泡，通过血液循环及透过血脑屏障到达机体各个组织器官，危害人体健康。PM2.5是细颗粒物中对人体健康危害最大的颗粒物，若气道颗粒物的过度沉积超出了纤毛的最大清除负荷，则对气道产生刺激，使气道上皮细胞炎性介质释放增加，引起炎性细胞浸润，进而引起或者加重咳嗽高敏感性慢性咳嗽、支气管哮喘、慢性阻塞性肺疾病、肺癌等一系列的呼吸系统相关疾病发生或者发展，因此研究不同污染物气体对生物健康效应的影响及其可能的机制具有重要意义。The human respiratory system is the body's first barrier to defend against external harmful substances, and it is the first to suffer the brunt of the damage. The particulate matter in motor vehicle exhaust, especially fine particulate matter and its attachments, can be inhaled by the human body into the small airways, enter the alveoli, and reach various tissues and organs of the body through blood circulation and through the blood-brain barrier, endangering human health. PM2.5 is the particulate matter that is the most harmful to human health. If the excessive deposition of airway particulate matter exceeds the maximum clearance load of cilia, it will stimulate the airway, increase the release of inflammatory mediators from airway epithelial cells, and cause inflammation. Infiltration of sex cells, and then cause or aggravate the occurrence or development of a series of respiratory system-related diseases such as cough hypersensitivity chronic cough, bronchial asthma, chronic obstructive pulmonary disease, lung cancer, etc. Therefore, the impact of different pollutant gases on biological health effects and Its possible mechanism is of great significance.

污染物气体暴露实验舱是进行动物暴露实验等基础研究的重要设备，不同的实验动物(如豚鼠、大鼠、小鼠等)在暴露实验舱内生存接受污染物气体染毒暴露，通过固定或改变暴露实验舱内污染物气体的浓度来研究不同实验动物对污染物气体的反应及相关健康效应。The pollutant gas exposure experimental chamber is an important equipment for basic research such as animal exposure experiments. Different experimental animals (such as guinea pigs, rats, mice, etc.) survive in the exposure experimental chamber and receive exposure to pollutant gases. Change the concentration of pollutant gases in the exposed experimental chamber to study the response of different experimental animals to pollutant gases and related health effects.

暴露舱实验通常是在实验室内进行，利用机动车发动机现场产生机动车尾气，机动车发动机可以为柴油机或者汽油机或者机动车尾气模拟发生器，在实验室内布置有设备间，设备间内放置冷却系统、新风系统等设备，机动车尾气在设备间内被降温、减速以满足实验需求。The exposure chamber experiment is usually carried out in the laboratory, using the motor vehicle engine to generate the vehicle exhaust gas on site. Cooling system, fresh air system and other equipment, vehicle exhaust is cooled and slowed down in the equipment room to meet the experimental needs.

但是机动车尾气发生设备在设备间内工作，以及机动车尾气在流通时，设备间内会产生大量的振动噪音，噪音不仅会影响实验动物的生存环境，同时也会影响实验人员的健康。However, when the vehicle exhaust gas generating equipment works in the equipment room, and when the vehicle exhaust gas is circulating, a large amount of vibration noise will be generated in the equipment room. The noise will not only affect the living environment of the experimental animals, but also affect the health of the experimental personnel.
