The invention discloses an anti-blocking device and method for closed collection of tail gas of a tar tank in a coal tar deep processing tank area, relates to the technical field of coal tar tail gas treatment. The technologies of nitrogen pressure supplement, tail gas emission control and nitrogen protection type pressure monitoring are adopted, so that the total amount of tail gas emission of the tank is greatly reduced, the problem of naphthalene blockage is solved, safe and reliable operation of the existing tank is ensured, the unorganized emission control standard of volatile organic compounds is completely met, and the environmental air quality is greatly improved. The device can be conveniently disassembled and maintained, and meanwhile, the device has high stability. 本发明公开了一种煤焦油深加工罐区焦油槽尾气密闭收集防堵装置及方法，涉及煤焦油尾气处理技术领域，采用了"氮气补压+尾气排放控制+氮气保护式压力监测"的技术，既大幅减少了槽罐尾气排放总量，又解决了萘堵塞的问题，确保了现有槽罐的安全和可靠运行，完全满足挥发性有机物的无组织排放控制标准，极大改善环境空气质量。能较方便地拆卸、维修，同时具有较强的稳固性。
