A cryopump regeneration method includes a temperature raising step of raising the temperature of a cryopanel so as to vaporize gas molecules condensed on the exhaust surface of the cryopanel, an evacuation step of evacuating a pump vessel, a determination step of determining whether the internal pressure of the pump vessel has reached a set pressure higher than the water vapor pressure at 0 DEG C, a pressure rise test step of stopping the evacuation and performing a pressure rise test, and an observation step of observing residual water based on the internal pressure of the pump vessel.

The invention discloses a dust filtration system of a mixed gas of high-temperature oil gas, water vapour and carbonaceous easy-precipitation substances. The system comprises a sealed separation chamber communicating a gas inlet pipe and a gas discharge pipe. A filtration mechanism is arranged in the sealed separation chamber. The outer surface of the filtration mechanism communicates with the gas inlet pipe, and the inner surface of the filtration mechanism communicates with the gas discharge pipe. A filtration body regeneration mechanism is arranged in the dust filtration system. According to the invention, the filtration body regeneration mechanism is arranged in the sealed separation chamber communicating the gas inlet pipe and the gas discharge pipe. When the filtration body works for a period of time, the filtration capacity of the filtration body cannot satisfy the requirement of normal working because the filtration capacity is greatly reduced due to tar and coal ash deposits on the surface and pores of the filtration body. The filtration body regeneration mechanism works, and the filtration body is recovered to a desired level. Regeneration is repeated, such that filtration body investment is directly reduced, and filtration body service life is greatly improved.

The invention discloses a microwave radiation reclaiming method for environment-friendly high-strength reclaimed rubber, and belongs to the technical field of waste rubber reclaiming. The method comprises the following steps of: mixing waste rubber outer tire crown powder with the particle size of 20 meshes, rosin and dipentene according to a certain proportion; uniformly feeding the materials with a certain thickness on a roller way conveying device; determining the length of a roller way according to microwave radiation time; arranging a high-frequency microwave radiation device on the roller way; conveying the materials on the roller way for reclaiming the materials by microwave radiation during conveying; continuously putting the reclaimed rubber materials into a cooling device through the roller way; directly discharging the cooled materials to an open mill for performing refining, wherein the refining temperature is controlled to be 35-50 DEG C; and refining at low temperature on the open mill for 20 minutes to obtain a refined rubber sheet with smooth surface and uniform texture. A test result shows that the tensile strength of the reclaimed rubber is more than 18MPa, the breaking elongation is over 400%, and the Weigert plasticity is 0.35-0.45. The microwave radiation reclaiming method has the advantages of environment friendliness, short reclaiming time, low reclaiming temperature, energy conservation and high production efficiency.
