The invention discloses a rotary heat storage heat exchanger based on the reversible chemical reaction heat effect. The rotary heat storage heat exchanger comprises a shell and a core. The core body comprises a heat storage part and a heat release part which are separated by a partition plate. And a reaction channel and a fluid channel are arranged in the heat storage heat exchanger. The heat storage part comprises a reaction channel and a hot fluid channel, and the heat release part comprises a synthetic reaction channel and a cold fluid channel. And fins are arranged outside the reaction channels. The working medium can be ammonium carbamate, carbon dioxide and ammonia gas, the ammonium carbamate reaction occurs at the temperature of 120 DEG C or below, and unstable low-grade waste heat can be continuously and effectively recycled. Continuous heat storage and heat release circulation are achieved through reversible reaction of the rotary heat exchanger and ammonium carbamate, and the heat storage density is
