The invention discloses a freezing blockage preventing device, which comprises a throttling valve, a tee short joint and a water nozzle assembly, wherein one end of the throttling valve is connected with one end of a wellhead of a gas well to reduce the pressure of the wellhead, the other end of the throttling valve is connected with a first end of the tee short joint, a second end of the tee short joint is connected with one end of the water nozzle assembly, a third end of the tee short joint is connected with a collecting and conveying pipeline, one side of the water nozzle assembly is connected to a heat tracing and water mixing pipeline, and the water nozzle assembly is used for spraying hot water in the heat tracing and water mixing pipeline to an outlet of the throttling valve, so as to avoid the freezing blockage of the throttling valve when oil-gas-water flows through the throttling valve and generates a hydrate. The freezing blockage preventing device has the advantages that the freezing blockage of the throttling valve can be prevented without using external heating equipment; the operation is simple, the cost is low, and the efficiency is high.
