A water cooling pipe nest is arranged at the center of thecyclone cylinder, fireproof materials are applied on the water cooling pipe nest to form a liquid slag membrane, so that the ash-retention rate of the cyclone furnace is increased, and the gasification carbon residues are seized for wall adhering combustion; a pipe sleeve is arranged on the outer wall of the center water cooling pipe nest; a center powder feeding sleeve pipe sleeve penetrates through a combustor and extends to the liquid slag membrane at the middle part of the center water cooling pipe nest to start to form a region; the gasification carbon residues are preheated by the centerpowder feeding sleeve pipe sleeve, and then are integrally transported into a high temperature region of the cyclone cylinder; through an air membrane separator, a high-oxygen-concentration air current is generated to be transported to the center powder feeding sleeve pipe to assist the gasification carbon residues to fire and combust, and the generated low-oxygen-concentration air current is used for performing supplementary secondary air to enable deep air separation effects of the cyclone cylinder to form, so that the fuel NOx generation quantity is reduced; and steam and slag water generated by cooled liquid slags are used in a powder making system to increase the energy utilization efficiency of the cyclone furnace. According to the system disclosed by the invention, high-efficient low-NOx combustion of the gasification carbon residues in the cyclone furnace can be realized, the ash-retention rate and the energy utilization efficiency of the cyclone furnace are increased.

A self-generating energy-saving wireless mouse that utilizes pressing to generate electricity
ActiveCN108595032BReduce consumptionAchieve energy saving effectDynamo-electric machinesInput/output processes for data processingControl theoryMechanical engineering
The present invention provides a self-generating energy-saving wireless mouse that utilizes pressing to generate electricity. A pressing power generation module and a rectification and filtering module are installed in the wireless mouse instead of dry batteries; wherein the pressing power generation module includes a lever, a spring, a magnetic metal rod and a coil. The spring extends downward from the fixed end of the upper cover of the mouse, and the bottom end is connected to a magnetic metal rod, which runs through the coil. The A end of the lever is connected to the left button of the mouse, and when the mouse is clicked, the B end floats up and touches The spring makes the magnetic metal rod cut the magnetic induction line of the coil; the rectification and filtering module is a bridge rectification circuit connected to two ends of the coil. When the mouse of the present invention is in use, when the left button is pressed, the lever drives the cutting magnetic induction line in the pressing power generation module to move, and the coil generates voltage, which becomes a stable standard voltage that can be supplied to the mouse after being rectified and stepped down by the rectifying and filtering module. The invention makes full use of the energy generated when the mouse is clicked to achieve the effect of energy saving, and has the advantages of low cost, high usability, environmental protection and the like.
