The invention belongs to the field of oil-gas exploration and research, and particularly relates to a device and a method for absorbing acid gas in a sedimentary rock organic carbon pretreatment process. The device comprises an acid-proof cover, an alkali liquor bottle, a liquor removal bottle and an air pump which are sequentially connected through acid-proof hard rubber pipes. According to the device, on the basis that an existing laboratory is not modified, acid mist generated by hydrochloric acid in the sedimentary rock organic carbon pretreatment process of the oil-gas geochemistry laboratory can be conveniently and completely absorbed, corrosion of acid mist in the laboratory and emission of waste gas are eliminated, and pollution-free emission of the laboratory is achieved. 本发明属于油气勘探研究领域，具体涉及一种吸收沉积岩有机碳前处理过程中酸气的装置及方法。所述装置包括防酸罩、碱液瓶、除液瓶和抽气泵，其中，防酸罩、碱液瓶、除液瓶和抽气泵通过防酸的硬胶管依次连接。通过该装置可以在不对现有实验室做任何改造的基础上，方便地将油气地球化学实验室沉积岩有机碳前处理过程中使用盐酸产生的酸气雾完全吸收，消除实验室酸雾的腐蚀和废气的排放，达到实验室无污染排放。
