Description

Technical Field

[0001] The utility model relates to the technical field of soot blowers, in particular to a steam soot blower with multi-layer heat insulation effect. Background Art

[0002] A soot blower is a device used to remove soot from the heating surface of a boiler. It is usually composed of a soot blowing pipe and an operating valve. It is usually installed on the furnace wall of the boiler furnace, horizontal flue, and tail flue. According to the structural type, there are several types, such as gun type, rotary type, and telescopic type.

[0003] Publication No. CN213237567U discloses a high-efficiency steam soot blower. The patent sets a motor forward and reverse rotation adjustment module so that when the steam soot blower is in use, the rotation direction of the rotating motor can be adjusted according to the use requirements, thereby effectively adjusting the rotation direction of the steam nozzle to ensure the soot blowing effect. However, the patent still has the following problems in actual use:

[0004] By setting the motor forward and reverse regulation module, when the steam soot blower is in use, the rotation direction of the rotating motor can be adjusted according to the use requirements, thereby effectively adjusting the rotation direction of the steam nozzle. However, when the steam nozzle is in use in actual use, high-temperature steam will circulate in the steam nozzle. When the steam passes through the nozzle, it contacts the pipe wall and causes heat transfer, which reduces the steam temperature. When the saturated steam temperature is exceeded, the water vapor in the steam will condense into liquid water to form condensed water. The generation of condensed water will affect the normal operation of the steam nozzle, reduce thermal efficiency, increase energy consumption, and may even cause equipment corrosion.

[0005] A steam soot blower with multi-layer heat insulation effect is proposed to solve the above problems. Utility Model Content
