[0006] The main pipeline is connected to the heater inlet flange and is welded to the heater inlet flange. It is distributed in a surrounding manner at a low position in front of the filtering unit. The main pipeline is made of stainless steel pipe, and the material is 304, 316, 316L or 321.

[0007] The expansion device is installed on the main pipeline and is welded to the main pipeline, and is used to offset the thermal expansion of the main pipeline during the heating process. The material of the expansion device is 304, 316, 316L or 321.

[0008] The hot curtain pipe joint is installed on the main pipeline and is welded to the main pipeline. The hot curtain pipe joint is composed of a stainless steel pipe and a stainless steel union welded together, and the material is 304, 316, 316L or 321.

[0009] The described hot curtain tube is installed on the hot curtain tube joint and connected to the hot curtain tube joint by a union structure. The hot curtain tube is made of stainless steel pipe, and the materials are 304, 316, 316L or 321. Beneficial effects

[0010] The cold protection device of the present invention has good low-temperature resistance and long service life.

[0011] For the cold protection device of the present invention, materials above 304 quality stainless steel are selected, and it has good corrosion resistance and can be used in extremely cold coastal environments.

[0012] The cold protection device of the present invention includes an expansion device, which can effectively offset the thermal expansion of the pipeline and increase the service life of the equipment.

[0013] For the cold protection device of the present invention, the hot curtain tube and the main pipeline are detachable structures, which meet the disassembly conditions of the filter unit, can effectively reduce the pre-filter space for air intake and air inlet filtration, thereby reducing the volume of the filtration equipment and meeting the requirements of light and small gas turbine equipment.
