The invention belongs to the field of flexible electronics devices, and particularly discloses a preparation method and a product of a shape adaptive fast response soft heater. The method comprises the following steps: (1) spin-coating a polyvinyl alcohol aqueous solution on a hard substrate and heating to cure the hard substrate to form a sacrificial layer; (2) processing the conductive materialinto a conductive layer by screen printing; 3) spin-coating a flexible polymer on the sacrificial layer and heating to cure the flexible polymer; (4) dissolving the sacrificial layer to strip the hardsubstrate; and (6) sticking a copper foil and an insulating layer on the initial soft heater body. The product is prepared by the above method. The soft heater has fast response speed, small requireddriving voltage, large deformation and good shape adaptability and can realize reliable grasping and heating of complex shape objects. Meanwhile, the thermal stability of the soft heater at high temperature is good and the performance of the soft heater can be adjusted by simply controlling the DC voltage of the power supply.

The invention provides a convective heat transfer flue-cured tobacco lamina re-curing method and device. The device comprises a rotary cylinder, a feeding device, a discharging device, a bidirectional airlock, a heat exchanger, a moisture discharging fan, a circulating fan and the like. A plurality of longitudinal heating plates are arranged on the inner wall of the rotary cylinder, a hollow shaft-shaped pipeline is arranged at the center of the cylinder and is divided into a front segment and a rear segment, and a plurality of high-temperature jet holes are formed in an outer pipe wall. After threshing and pneumatic separation processes, flue-cured tobacco lamina are fed into the rotary cylinder for processing, the moisture content of the flue-cured tobacco lamina is rapidly reduced, the moisture content of the processed flue-cured tobacco lamina is up to 12-13%, and the tobacco lamina directly undergoes a next packaging process. The raw material processing quality is improved, the device and the process are simplified, and energy consumption can be effectively reduced.

The invention relates to the field of methanol hydrocarbon preparation, and discloses a method and a system for methanol hydrocarbon preparation. The method comprises the following steps of implementing in a system comprising a fluidized bed reactor, a heat exchange device and a gasifier, exchanging the heat of raw material containing liquid methanol and the heat of process gas from the heat exchange device in the gasifier, and gasifying the methanol; exchanging the heat of gasified raw material containing methanol and the heat of process gas from the heat exchange device in the gasifier, injecting the produced process gas containing hydrocarbon into the heat exchange device, and exchanging heat; removing one part of heat produced by reaction by a heat removing device in the reactor. The invention also discloses a system for implementing the method. The method has the advantages that by adopting a fluidized bed, the reaction matter is in full contact with a catalyst, the service life of the catalyst is uniform, the activity is improved, and the yield rate of hydrocarbon is improved; the heat transfer is uniform and rapid, the coefficient is large, the reaction heat can be timely removed, and the temperature in the reactor is stable and controllable; the output of steam is increased, the additional consumption of steam is not needed, and the electric consumption is decreased.
