技术领域Technical field
本发明属于分布式能源以及空气调节技术领域，尤其涉及一种PEMFC联供的新风净化及除湿加湿装置及其控制方法。The invention belongs to the technical fields of distributed energy and air conditioning, and in particular relates to a PEMFC co-supplied fresh air purification, dehumidification and humidification device and a control method thereof.
背景技术Background technique
目前，能源是国民经济发展的命脉，是国家发展的重要支柱，随着全球对发展新能源的高度关注，氢能技术成为新一轮科技革命和产业变革的竞争前沿。目前氢气的生产、储存、运输和使用等技术目前均已非常成熟、安全、可靠，以氢气为原料的质子交换膜燃料电池(PEMFC)得到迅速发展。PEMFC具有能量转换效率高、没有排放物污染、发电效率受负荷影响小、原料来源广泛等优点，是一种极具商业化推广潜力的节能环保技术，很好符合了当前“氢进万家”的政策。商业化的质子交换膜燃料电池发电效率受限于极化损失一般在(40-60)％之间，仍有将近一半的能量以低品位热能(70-100)℃形式耗散，造成巨大的能量浪费。在PEMFC运行时，会产生大量余热，如何利用这些余热，是当前研究的热门问题。热电联供(CHP)系统是使用单一或多种驱动能源同时产生电能及可用热能，实现能量梯级高效利用的能源系统。At present, energy is the lifeblood of national economic development and an important pillar of national development. As the world pays great attention to the development of new energy, hydrogen energy technology has become the forefront of competition in a new round of scientific and technological revolution and industrial transformation. At present, the technologies for the production, storage, transportation and use of hydrogen are now very mature, safe and reliable. Proton exchange membrane fuel cells (PEMFC) using hydrogen as raw material have developed rapidly. PEMFC has the advantages of high energy conversion efficiency, no emission pollution, power generation efficiency is less affected by load, and a wide range of raw material sources. It is an energy-saving and environmentally friendly technology with great potential for commercialization and is well in line with the current "hydrogen entering thousands of households" policy. The power generation efficiency of commercial proton exchange membrane fuel cells is limited by polarization loss, which is generally between (40-60)%. Nearly half of the energy is still dissipated in the form of low-grade thermal energy (70-100)°C, causing huge Waste of energy. When PEMFC is running, a large amount of waste heat will be generated. How to utilize this waste heat is a hot issue in current research. A combined heat and power (CHP) system is an energy system that uses a single or multiple driving energy sources to simultaneously generate electrical energy and usable heat energy to achieve efficient utilization of energy cascades.
新风系统是根据在密闭的室内一侧用专用设备向室内送新风，再从另一侧由专用设备向室外排出，在室内会形成“新风流动场”，从而满足室内新风换气的需要的设备。吸附式新风系统是一种热驱动的除湿加湿技术，可采用多种低品位热源，因此PEMFC运行时产生的余热可以应用于吸附式新风系统中。固体吸附除湿是一种有效的空气除湿方法，常用的固体吸附除湿材料包括硅胶、活性氧化铝、分子筛及活性炭、MOFs材料等，与吸收式除湿再生相比，其具有以下优点：(1)系统结构简单，控制简便；(2)无毒，吸附剂不会蒸发残留于空气中；(3)系统投资和运行费用都较低。正因为具备多种优势，吸附式除湿再生技术得到了广泛的关注和研究。除此之外，固体吸附剂还可依据多孔的特性，利用其大表面积及多孔结构能与空气中尘埃粒子充分接触，通过分子间的相互作用力捕获颗粒污染物。因此，有效结合PEMFC与新风除湿机具有重要的现实意义。The fresh air system is based on the use of special equipment on one side of a closed indoor room to send fresh air into the room, and then discharge it to the outdoors through special equipment on the other side. A "fresh air flow field" will be formed indoors to meet the needs of indoor fresh air ventilation. . The adsorption fresh air system is a heat-driven dehumidification and humidification technology that can use a variety of low-grade heat sources. Therefore, the waste heat generated during PEMFC operation can be used in the adsorption fresh air system. Solid adsorption dehumidification is an effective air dehumidification method. Commonly used solid adsorption dehumidification materials include silica gel, activated alumina, molecular sieves, activated carbon, MOFs materials, etc. Compared with absorption dehumidification regeneration, it has the following advantages: (1) System Simple structure and easy control; (2) Non-toxic, the adsorbent will not evaporate and remain in the air; (3) System investment and operating costs are low. Because of its various advantages, adsorption dehumidification regeneration technology has received widespread attention and research. In addition, solid adsorbents can also use their large surface area and porous structure to fully contact dust particles in the air based on their porous characteristics, and capture particulate pollutants through intermolecular interactions. Therefore, effective combination of PEMFC and fresh air dehumidifier has important practical significance.
通过上述分析，现有技术存在的问题及缺陷为：现有技术中无法有效减少新风中的污染物颗粒，降低了室内空气品质。Through the above analysis, the problems and defects of the existing technology are: the existing technology cannot effectively reduce the pollutant particles in the fresh air and reduces the indoor air quality.
