The invention relates to a method for making electric conduction patterns on a metal-foil-clad insulating substrate. The method comprises the steps that insulating envelope grooves are machined in the periphery of a conducting layer which needs to be reserved, and machining is conducted twice or more when excessively narrow isolated wires are encountered; a conducting layer which needs to be removed is subdivided into a plurality of strip-shaped heat-insulating small blocks, wherein one end of each small block is narrowed, the other end of each small block is widened, and the narrowed end of one metal foil layer small block and the widened end of another metal foil layer small block adjacent to the metal foil layer small block are arranged in a corresponding mode; next, laser beams are projected onto the heat-insulating small blocks obtained after subdivision, so that the small blocks are separated from the substrate material and removed. According to the method for making the electric conduction patterns on the metal foil-clad insulating substrate, by means of adjusting the projection parameters, a projection path and the projection environment of a laser, the conducting layer on the substrate material is removed, a predetermined electric conduction structure is formed, corresponding technological processes adopted for manufacturing the electric conduction structure through a chemical method, a physical method and a laser method in the prior art are replaced, the laser is directly used for forming and making the electric conduction patterns, as a result, multiple devices and materials are omitted, environmental friendliness is achieved, the process is short, the technology is simple and easy to implement, and the method is suitable for manufacturing multiple types of circuit board samples with higher accuracy in a small-batch mode and general circuit boards.

The invention relates to a method for selectively removing a conductive layer on a baseplate material. The method comprises the following steps: processing to manufacture an insulated enveloping channel on the periphery of a to-be-reserved conductive layer, wherein an isolated wire with over-narrow width is processed twice or more than twice; subdividing a to-be-removed conductive layer into a plurality of insulated small blocks, wherein the adjacent insulated small blocks are of complementary shapes such as inverted quadrangle, trapezoid or triangle; projecting electromagnetic waves onto the subdivided insulated small blocks so as to ensure that the subdivided insulated small blocks are separated from the baseplate material to be removed, wherein during heating, the projected laser moves from the narrower end of each small block of the conductive layer to the wider end of each small block. According to the method, the projecting parameter, projecting path and projecting environment of the laser are regulated and the conductive layer on the substrate material is removed, so that a preset conductive structure is formed, and the method can be used for replacing a corresponding technical process adopted in the process of manufacturing a conductive structure by virtue of an existing chemical method, an existing physical method and an existing laser method.

The invention discloses a biogas tea fixing machine, which comprises a frame, a horizontal tea fixing roller arranged on the frame, a driving device driving the tea fixing roller to roll, and a heating device used for heating the tea fixing roller. The biogas tea fixing machine is characterized in that: the heating device comprises a stove and a biogas combustion device arranged under the tea fixing roller; the biogas combustion device comprises a biogas delivery pipeline which is connected with a biogas digester and provided with a valve, and a plurality of high temperature-resistant biogas ejectors connected with the output end of the delivery pipeline; the biogas ejectors pass through the side wall of the stove to extend into the hearth of the stove; and biogas nozzles of all the biogas ejectors are arranged at equal intervals along the length direction of the hearth. The fixing machine is provided with heat by the combustion of the biogas, and the combustion cost is lower, so the manufacturing cost of tea is reduced; the main component of the biogas is methane, and generates water and carbon dioxide after combustion, so the environment is protected; besides, the combustion value of the biogas is high, so the biogas provides enough heat for the fixing machine; therefore, the produced tea has higher quality.

The invention discloses a device and method for autothermally producing high-purity hydrogen by catalytic cracking of methane. The device mainly includes a cracking reactor, a regeneration reactor, a riser, a cyclone separator, a filter device and a flow sealing valve; the method includes: Methane goes backwards with the catalyst in the cracking reactor and undergoes a catalytic cracking reaction to obtain hydrogen and deactivated catalyst. After impurity removal and separation, high-purity hydrogen is obtained. The catalyst carries carbon deposits into the regeneration reactor for regeneration to generate syngas and regenerated catalyst. The regenerated catalyst is transported to the cyclone separator through the riser, and then re-enters the cracking reactor for recycling after removing impurities. The present invention can not only fully recover the catalytic activity of the deactivated catalyst, produce high-purity hydrogen, but also use the heat released by the combustion of carbon deposits on the deactivated catalyst to provide heat for the regeneration reactor, and use the heat carried by the regenerated catalyst to provide heat for the cracking reactor. Heat, so that the system runs by self-heating, reducing energy consumption and saving costs.
