The invention discloses a heavy metal polluted farmland restoration straw gasification combustion and heat energy grain drying coupling technology, and belongs to the technical field of biomass thermal conversion. The method comprises the following steps of (1) selecting to establish a straw gasification combustion furnace and grain drying coupling type base near a phytoremediation project; (2) mechanically packaging rice straws subjected to phytoremediation on site, and transporting the packaged rice straws to the grain drying base; (3) directly feeding the straw packages into a gasificationcombustion furnace to be gasified in a gasification chamber, enabling generated combustible gas to enter a combustion chamber to be fully combusted, and generating hot smoke gas; and (4) enabling thehot smoke gas to exchange heat with external air in a heat exchanger, heating the external air to form clean hot air, and feeding the hot air into a grain dryer through a pipeline to dry grains. According to the method, mechanization is completely achieved, and the rice drying cost of farmers can be saved on; and smoke gas after gasification combustion is discharged after dust removal treatment, charcoal ash is recovered in a unified mode, and therefore, the problem of secondary pollution of rice straws polluted by heavy metal is solved.
