A backflow gas heating and throttling device, and a surface throttling system, where the surface throttling system includes a Christmas tree, a backflow gas heating and throttling device, and a gas collection pipeline connected in sequence. A pipeline between the Christmas tree and the backflow gas heating and throttling device and the gas collection pipeline are both provided with a valve, a thermometer, and a pressure gauge, and the gas collection pipeline is further provided with a flow meter. The backflow gas heating and throttling device includes a gas inlet pipe, a heat pipe, a guide cone, an outer throttle pipe, an annular cover, a tapered pipe, a gas outlet pipe, a throttle plate I, a throttle plate II, and a heating rib, thereby increasing the natural gas temperature before throttling and further heating the natural gas during throttling to prevent hydrate generation from causing blockage.
