Description

Technical Field

[0001] The invention relates to the technical field of vacuuming technology, and in particular to an anti-blocking system for vacuuming technology. Background Art

[0002] Cryogenic liquefied gases such as liquid oxygen, liquid nitrogen and liquefied natural gas are mainly transported through vacuum cryogenic insulated pipes. Vacuum cryogenic insulated pipes are composed of inner pipes, outer pipes and multiple layers of insulation materials. The multiple layers of insulation materials in the interlayer are composite to reduce radiation heat transfer, and the interlayer is evacuated to a high vacuum state to reduce convection heat transfer. The inner and outer pipes are isolated with low thermal conductivity materials to reduce solid heat transfer, thereby controlling the cold loss of the inner pipe to a minimum, fully meeting the long-distance transportation of cryogenic liquids. The vacuum degree of the interlayer directly determines the low-temperature performance of the vacuum cryogenic insulated pipe and is a key factor in reducing evaporation losses. The vacuum degree of the vacuum cryogenic insulated pipe depends on the vacuuming process. Minimizing the content of moisture and other inclusions in the vacuum interlayer can obtain a higher vacuum degree and reduce the cold loss of cryogenic liquids. In order to meet the large-scale production of vacuum cryogenic insulated pipes, the vacuuming process must also meet the requirements of vacuuming several vacuum pipes at the same time.

[0003] In the prior art, when the cyclone separator is evacuated, the high vacuum pump group is directly connected to it, and the required vacuum is achieved through the continuous operation of the pump group. However, due to the high humidity inside the reactor, the existing cyclone separator will have adhesion and blockage at the inlet end of the cyclone separator, and the material in the connecting pipeline between the cyclone separator and the reactor will also have adhesion and blockage, thereby reducing the working efficiency of the vacuum process.
