The application discloses a device and method for preventing pollution and blockage of a cold stage system of a scanning electron microscope, the device comprising a main low-temperature gas path system and a normal-temperature nitrogen branch, low-temperature nitrogen discharged from the main low-temperature gas path system is divided into two paths, and is respectively connected to a cold hydrazine and a cold stage and is independently controlled through a flow valve. In order to solve the problems that a sample is easily polluted and a gas path is easily blocked during temperature rising in the prior art, a normal-temperature nitrogen branch is additionally arranged on the cold stage gas path through a three-way valve. During a system temperature rising stage, the cold stage low-temperature gas path is closed and the normal-temperature nitrogen branch is opened, dry nitrogen is blown to the cold stage, the cold stage is rapidly heated under positive pressure protection, meanwhile, the cold hydrazine continuously obtains low-temperature nitrogen, and an ultralow temperature is maintained. The above-mentioned measures ensure that a large temperature difference (such as > 150 DEG C) always exists between the cold hydrazine and the cold stage, ensure that pollutants are preferentially captured by the cold hydrazine, effectively protect the surface of the sample to be clean, and fundamentally prevent the gas path from being blocked due to moisture backflow.

This utility model relates to the field of reactor heating and insulation technology, and in particular to an electric heating device for a reactor. Specifically, it includes two mirror-symmetrically arranged heaters. Each heater has a heating shell with a cover-like structure, and through slots are formed on opposite sides of the heating shell. When the heaters are assembled, the through slots together form a channel that covers and accommodates all or at least part of the reactor. An insulation layer is provided inside the heating shell, and slots in the insulation layer form a heating zone communicating with the channel. An electric heating unit is installed within the heating zone. This utility model uses two mirror-symmetrically arranged, cover-like heating shells to form heaters, which can be used to cover and accommodate the reactor and use electric heating units to heat and insulate the reactor, achieving effective and safe heating of the reactor without any pollution to the gas inside the reactor.
