The invention relates to a regenerative chemical protection device, belonging to the technical field of nuclear biochemical protection; the device comprises a front sensor, a first reversing valve, a first toxin filtering unit, a second reversing valve, a desorption fan, a rear sensor and an exhaust fan; the front sensor, the first reversing valve, the second toxin filtering unit, the second reversing valve, the rear sensor and the exhaust fan are sequentially connected in series through an air inlet pipeline; the desorption fan, the second reversing valve, the first toxin filtering unit and the first reversing valve are communicated in sequence through an air outlet pipeline; the desorption fan is communicated with the rear sensor through an air outlet pipeline; the outlet end of the gas outlet pipeline points to the external toxic gas flow environment; the invention abandons the reliable protection of high-volatility toxin agents by adjusting the pressure of the system, but adjusts the structural constant B of the activated carbon, thereby achieving the same protection effect as the pressurization of the system. |
