The present application relates to solid waste resource comprehensive utilization technical field, disclose a kind of calcination desulfurization-electric furnace reduction processing laterite nickel ore acid leaching residue method, comprising the following steps: S1.laterite nickel ore acid leaching residue and auxiliary material are used as raw material, oxygen-enriched air and first fuel are introduced into raw material to carry out calcination desulfurization, obtain sulfur-containing flue gas and desulfurization hot slag;S2.desulfurization hot slag obtained in S1 with second reducing agent is directly put into electric furnace and is reduced smelting, obtain molten iron, reduction smelting flue gas and reduction smelting slag, desulfurizer is added to the molten iron and is desulfurized, and iron ingot is prepared;S3.reduction smelting slag is obtained after water quenching treatment water quenching slag, the water quenching slag is mixed with excitation agent, after drying, grinding, obtain active micro-powder material.This method realizes laterite nickel ore acid leaching residue full resource comprehensive utilization, fully recycles residual valuable metal including Fe, Ni, realizes the full development and utilization of valuable metal, sulfur, tailings and other slag components.

This invention provides a warm acupuncture device with temperature control, belonging to the field of warm acupuncture technology. It includes acupuncture needles, a fixed tube, a movable tube, a fixed groove, a fixed crossbar, an upper connecting rod, and an inclined rod. The invention utilizes a movable tube, a mounting frame, a fixed groove, and a pressing plate. By pressing the lower end of the pressing plate inward, the clamping block penetrates the fixed tube, releasing the acupuncture needle. At this point, the movable tube and mounting frame can be lifted upward, separating the acupuncture needle from the moxa stick and reducing the needle's temperature. This achieves direct and rapid temperature control by allowing the acupuncture needle to contact and separate from the burning moxa stick. This solves the problem of existing warm acupuncture temperature control devices that regulate temperature by controlling the number of vents, which is slow and affects treatment effectiveness. Furthermore, the acupuncture needles inserted into the skin, bearing a large load, are not stable enough when supported solely by the needles. Additionally, ash can fall from the vents of the container holding the burning moxa stick, potentially burning the patient.

The utility model relates to the technical field of combustors, in particular to an incandescent light combustor which comprises a contraction section, and the diameter of an inlet of the contraction section is larger than that of an outlet of the contraction section. An outlet of the contraction section is communicated with an inlet of the mixing chamber; the diameter of an inlet of the diffusion section is smaller than that of an outlet of the diffusion section, and the inlet of the diffusion section is communicated with the outlet of the mixing chamber; the air pipe section is communicated with the mixing chamber; and the windproof cover is communicated with the outlet of the diffusion section. According to the incandescent light combustor, the Venturi effect is ingeniously applied, the combustion efficiency, the combustion stability and the flame intensity of the combustor are improved, fuel gas consumption is reduced under the same combustion effect, the production cost is reduced, and therefore the functions of effectively resisting wind and rain, reducing the consumption of combustion gas, facilitating successful ignition at a time and achieving continuous and stable combustion are achieved.
