Heating device for heat preservation of gas field foam scrubbing agent

The utility model provides a heating device for heat preservation of a gas field foam scrubbing agent. The heating device comprises a water tank, a burning chamber is arranged at the bottom end of the water tank, a heating furnace is arranged in the burning chamber, a heat isolation cabinet is arranged on one side of the water tank, and a hot water circulation pipe is led out from one lateral end of the water tank and transversely penetrates through the heat isolation cabinet to be led into the top end of the water tank. A foam scrubbing agent storage tank for storing the foam scrubbing agent is arranged in the heat isolation cabinet, and the hot water circulation pipe transversely penetrates through the foam scrubbing agent storage tank in a sinuous coil shape; a foam scrubbing agent infusion opening is formed in the top end of the foam scrubbing agent storage tank, and a foam scrubbing agent output pipe is arranged at the bottom end of the foam scrubbing agent storage tank. The foam scrubbing agent storage tank is heated through the hot water circulation pipe, so that the foam scrubbing agent is heated, and heat exchange between the hot water circulation pipe and the foam scrubbing agent storage tank is carried out; low-temperature water obtained after heat exchange enters the water tank along the pipe to be heated, circulation utilization on the water is achieved, energy conservation and environmental protection are achieved, freezing blocking of the foam scrubbing agent in a low-temperature environment is avoided, and it is guaranteed that a water-production gas well can conduct continuous production in the low-temperature environment.
