Abstract: The present disclosure relates to the technical field of pyrolysis and improvement of caking middling coals, in particular to a low temperature pyrolysis method of a caking middling coal. The present disclosure provides a low temperature pyrolysis method of a caking middling coal, including the following steps: conveying the caking middling coal into a pyrolysis reactor through a top of the pyrolysis reactor; dividing a reaction chamber of the pyrolysis reactor into a drying section, a softening section, a melting and depolymerization section, a solidification section, and a cooling section by means of multi-channel gas distribution; and conducting zoned temperature control-based pyrolysis to obtain semi-coke at a bottom of the reactor as well as tar and coal gas at the top of the reactor. The pyrolysis method can well avoid caking and swelling of the caking middling coal during pyrolysis.

Abstract: A connecting mechanism of a flexible pipe and an outlet device, includes a pipe fixing seat fixedly connected to a flexible pipe, an outlet fixing seat fixedly connected to an outlet device and a joint having a ball joint. Water in the flexible pipe is deflected to the outlet device by the pipe fixing seat and the joint. The joint is fixedly connected to the outlet fixing seat and the outlet fixing seat is disposed with a self-lock surface surrounding the ball joint. An end of the pipe fixing seat is concaved with an assembly groove. The groove opening of the assembly groove protrudes inwardly with an anti-off portion. The ball joint is assembled in the assembly groove by the elastic deformation of the end portion of the pipe fixing seat. The anti-off portion connects the ball joint to the pipe fixing seat.

Abstract: A device for detecting electrical impedance by utilizing a theory of excitation and response signals and method thereof, wherein the excitation signal is a square wave excitation current signal (1), the response signal on a target is transformed to a square wave signal with appropriate amplitudes by buffering, amplifying, RC filtering and differential amplifying, then is transformed to a digital signal at a proper time by an analog-to-digital converter. The response signal is sampled once when at high level and once when at low level for every circle by the ADC, and a sample V1 and a sample V2 are obtained respectively, difference of the samples is taken as a detecting result for one circle. An average value of the detecting result from a plurality of circles is taken as a final result. Information of electrical impedance is illustrated by the final result because the excitation current signal is constant.

Abstract: A remotely adjustable orifice plate arrangement for a generator is provided. The arrangement includes an enclosed generator with an interior wall including an orifice through which a fluid flows. The arrangement also includes a first plate including an orifice and a remotely controllable motor. The first plate is coupled to the interior wall within a flow area of the generator such that at least a portion of the orifice overlaps the orifice of the interior wall. The arrangement also includes an adjustable orifice plate including an orifice wherein the adjustable orifice plate slides relative to the first plate to determine the size of a resultant orifice of the interior wall. The motor selectively controls the slideable movement of the adjustable orifice plate relative to the first plate and is controlled remotely from outside the enclosed generator. A method to remotely adjust fluid flow within an enclosed generator is also provided.
