Description
技术领域technical field
本实用新型属于空气净化技术领域，具体涉及一种二氧化碳净化机。The utility model belongs to the technical field of air purification, in particular to a carbon dioxide purifier.
背景技术Background technique
人员密集空间包括轨道客车、公路汽车、飞机、轮船、电影院、会议室和车站等场所，其特点是只有人员进入这些空间后，才形成人员密集场所，不是全天候的人员密集，因此采暖通风空调设计配套的新风换气量有限，特别是使用空调时，太大的新风量将增加空调系统热负荷和能耗。国家对公共场所卫生规定的二氧化碳浓度限值为≤0.15%，如果大气的二氧化碳浓度为0.03%，满足国家规定需要的人均新风量为18.3m3/h，很多人员密集场所受空间、结构、设备和能源等因素的限制，往往达不到人均新风量18.3m3/h的要求，有时可能低于人均新风量10m3/h，这样的场所二氧化碳浓度将超过0.15%，达到0.25%或更大值，对人员的身体健康产生不利影响。因此，在不增加新风量的情况下降低人员密集场所的二氧化碳浓度，保证人员居留期间的身体健康，提高空调设备的能效，已经成为节能环保需要重点研究的问题。Crowded spaces include rail cars, road cars, airplanes, ships, cinemas, conference rooms, stations, etc., which are characterized by the formation of crowded places only after people enter these spaces, not all-weather crowded places, so heating, ventilation and air conditioning design The supporting fresh air exchange rate is limited, especially when the air conditioner is used, too much fresh air will increase the heat load and energy consumption of the air conditioning system. The national health regulations for public places have a carbon dioxide concentration limit of ≤0.15%. If the atmospheric carbon dioxide concentration is 0.03%, the per capita fresh air volume that meets the national requirements is 18.3m 3 /h. Many crowded places are limited by space, structure, and equipment. Due to the limitation of energy and other factors, it often fails to meet the requirement of 18.3m 3 /h per capita fresh air volume, and sometimes may be lower than 10m 3 /h per capita fresh air volume. In such places, the carbon dioxide concentration will exceed 0.15%, reaching 0.25% or greater value, adversely affecting the health of personnel. Therefore, reducing the carbon dioxide concentration in densely populated places without increasing the fresh air volume, ensuring the health of people during their stay, and improving the energy efficiency of air-conditioning equipment have become key research issues for energy conservation and environmental protection.
目前相对密闭空间中二氧化碳净化的主要技术有：分子筛吸附、固态胺吸附、化学吸收、膜渗透等方式。与其他技术相比吸附分离技术具有技术成熟、能耗低、操作弹性大、自动化程度高、吸附剂使用寿命长、无二次污染等优势。特别随着吸附剂的不断创新开发、应用工艺的不断更新，采用可再生变压吸附原理分离浓缩低浓度二氧化碳气体成为最佳选择。At present, the main technologies for carbon dioxide purification in relatively confined spaces are: molecular sieve adsorption, solid-state amine adsorption, chemical absorption, membrane permeation and other methods. Compared with other technologies, adsorption separation technology has the advantages of mature technology, low energy consumption, large operating flexibility, high degree of automation, long service life of adsorbent, and no secondary pollution. Especially with the continuous innovation and development of adsorbents and the continuous updating of application processes, it has become the best choice to separate and concentrate low-concentration carbon dioxide gas by using the principle of regenerative pressure swing adsorption.
然而目前所用的一些分离方法存在设备昂贵、能耗高、分离效果差等缺点，极大限制了二氧化碳分离技术在相对密闭空间中的应用。而变压吸附法因其独有的特点在该领域内越来越受到重视。However, some separation methods currently used have disadvantages such as expensive equipment, high energy consumption, and poor separation effect, which greatly limit the application of carbon dioxide separation technology in relatively confined spaces. The pressure swing adsorption method has been paid more and more attention in this field because of its unique characteristics.
本实用新型采用变压吸附法对相对密闭空间中二氧化碳进行净化，且只用一个二氧化碳吸附塔，使设备小型化，满足安装空间有限，不用连续不间断地净化二氧化碳的场合，对于轨道客车、公路汽车、飞机、轮船等移动交通工具和电影院、会议室和车站等存在人员高低峰的固定场所特别适用。The utility model adopts the pressure swing adsorption method to purify carbon dioxide in a relatively closed space, and only uses one carbon dioxide adsorption tower, which makes the equipment miniaturized and meets the occasions where the installation space is limited and does not need to continuously purify carbon dioxide. It is especially suitable for mobile vehicles such as automobiles, airplanes, and ships, and fixed places such as movie theaters, conference rooms, and stations that have high and low peaks of people.
