This invention discloses a high-temperature, high-dust-content flue gas purification device, relating to the field of flue gas purification technology. The device includes an adjustable purification structure comprising multiple ceramic filter elements. SCR catalyst components are coated on the surface of each ceramic filter element. A swirling ammonia injection grille is installed at the inlet end of each ceramic filter element. An attitude adjustment mechanism is connected to the purification structure. A PLC control system is electrically connected to the attitude adjustment mechanism, which controls the ceramic filter elements of the purification structure to switch between vertical, inclined, and parallel settings. In the vertical setting, flue gas passes through the filter element in a straight line from top to bottom or bottom to top. In the inclined setting, flue gas passes through obliquely, forming a "Z"-shaped path. In the horizontal setting, flue gas flows laterally through the filter element, and particulate matter is deposited downwards under gravity. This invention solves the problem of low removal efficiency of fine particulate matter, achieving highly efficient purification of high-temperature, high-dust-content flue gas, and is particularly suitable for treating high-emission flue gas under complex operating conditions.

The application is a method for treating goaf by harmless filling of phosphor tailings, which first treats the phosphor tailings into general industrial solid waste I, and the treatment method uses tailings slurry generated by a phosphor flotation plant as raw material, adjusts the pH value to neutral by adding quicklime or lime milk after thickening, and then performs 2 times of filtration treatment, adds the filtrate of secondary filtration into the obtained filter cake, adjusts to paste state, obtains phosphor tailings paste, and fills the open pit to realize open pit treatment and ecological restoration. The method can treat the tailings slurry generated by the phosphor flotation plant into I-class solid waste, can store the tailings without building a new tailings pond, and under the condition that the state does not approve the new tailings pond, the tailings treated to reach the I-class solid waste discharge standard can fill and treat the open pit, and under the premise of harmless treatment of the phosphor tailings, the safety hazard of the open pit is eliminated.

This invention relates to the field of plasma chemistry and discloses a high-throughput plasma reaction device and a method for decomposing hydrogen sulfide, comprising: an inner cylinder (1) containing reaction tubes (14); an outer cylinder (2) nested outside the inner cylinder (1); a central high-voltage electrode (3); grounding electrodes (4) respectively surrounding or forming sidewalls on the outer walls of each of the reaction tubes (14); a blocking medium (6) disposed on at least a portion of the outer surface of the central high-voltage electrode (3); the ratio between the distance L1 between the outer wall of the blocking medium and the inner wall of the grounding electrode and the length L2 of the discharge region is: L1:L2 = 1:(0.5~6000). The high-throughput plasma reaction device provided by this invention can achieve continuous and stable hydrogen sulfide decomposition process at a significantly higher hydrogen sulfide conversion rate, and the device can achieve long-term operation.

This invention relates to the field of drying equipment technology and discloses a dry-mixed mortar drying device, including a frame and a drying tank. Two heating plates are symmetrically arranged on the frame, and the drying tank is rotatably mounted on the frame. The drying tank is equipped with an exhaust structure, and a stirring mechanism is provided inside the drying tank. A drive mechanism is provided on the frame to drive the drying tank to rotate. The drive mechanism drives the drying tank and the stirring mechanism to rotate. The frame includes a lifting frame that drives the drying tank, heating plates, and drive mechanism to rotate. A dustproof discharge mechanism and a discharge trough are provided below the drying tank. A horizontal pressing mechanism is provided inside the discharge trough. This invention systematically solves the technical problems of traditional dry-mixed mortar drying devices in terms of uniformity, efficiency, dust prevention, and maintenance through structural innovation and functional integration. The drive mechanism can flexibly switch between synchronous rotation of the drying tank and the stirring mechanism or rotation of the stirring mechanism alone, reducing energy consumption while ensuring drying effect.
