Description

Technical Field

[0001] This utility model relates to the field of heating equipment, and in particular to a special hot air blower for high-pressure gas heating. Background Technology

[0002] High-pressure gas heating equipment is a device that converts electrical energy or other forms of energy into heat energy and heats high-pressure gas. Its working principle mainly involves using internal heating elements (such as resistance wires, heating tubes, ceramic heating elements, etc.) to convert electrical energy or other forms of energy into heat energy, and then transferring this heat energy to the high-pressure gas through heat conduction, convection, or radiation, thereby raising its temperature.

[0003] Existing patent CN 210399896 U discloses a high-pressure hot air blower. A high-pressure blower for generating high-pressure gas and a hot air blower for heating high-pressure gas are provided on a movable base. The hot air blower includes an outer casing with a cavity. A heater heat source connected to the high-pressure blower through a vent pipe is inserted into the outer casing. The heater heat source includes a heating core made of ceramic honeycomb nickel-chromium alloy heating wire and a high-pressure resistant stainless steel tube wrapped around the heating core. The stainless steel tube is wrapped with high-temperature resistant heat-insulating asbestos. An air outlet is provided on the heating core and a temperature detection probe is provided inside the air outlet. An electronic control board connected to the heating core, the temperature detection probe and the high-pressure blower is provided inside the outer casing.

[0004] The aforementioned patent uses a honeycomb structure heater. However, when using a honeycomb structure, all the gas needs to pass through the honeycomb holes, and the circular size of the honeycomb heater is not suitable for pipes, which increases the difficulty of sealing the connection of the honeycomb heater.
