This utility model discloses a cyclone separator for a biomass circulating fluidized bed boiler, comprising a flue gas inlet section, a gas-solid two-phase separation section connected to the flue gas inlet section, a flue gas outlet section connected to the top and bottom of the gas-solid two-phase separation section respectively, and a solid return section. The solid return section includes multiple coaxially connected and fixedly connected solid return straight sections and multiple solid return conical sections, which are arranged at intervals in the vertical direction. Flue gas flows in from the flue gas inlet section, rotates along the inner wall of the gas-solid two-phase separation section, and achieves gas-solid two-phase separation through centrifugal force. The gas phase flows out through the flue gas outlet section, and the solid phase is returned from top to bottom through the solid return section. Through segmented and optimized solid return path and gas-solid separation flow field, the intermittent blockage problem caused by alkali metal adhesion in traditional cyclone separators is solved, avoiding forced boiler load reduction or shutdown. It is especially suitable for biomass combustion scenarios with complex fuel types and variable ash composition.

The utility model discloses treatment and recovery equipment for waste pulp in paper product production, which relates to the technical field of paper product processing and comprises a tank body and a pulp outlet pipe, the pulp outlet pipe is fixedly arranged at the central position of the upper part of the tank body, and a pipe orifice vertically extends into the tank body and extends to the middle of the tank body; the lower side of the tank body is movably connected with a plurality of combined wall sheets, the plurality of combined wall sheets are circumferentially arranged around the central axis of the tank body, and the inner cavity wall of the tank body is jointly enclosed in a manner that the adjacent combined wall sheets are obliquely overlapped; when the device is used for treating, waste slurry tangentially enters from the upper side of the tank body, and naturally forms a spiral inner rotational flow along with the wall surface of the inner cavity in the process of flowing downwards along with gravity, so that solid impurities and cellulose slurry in the waste slurry are centrifugally separated, the cellulose slurry is sucked away and recycled by the slurry outlet pipe in the center, and the impurities are spirally discharged downwards; the device has the characteristic of high-efficiency separation of slag and slurry.

This application relates to the field of environmental monitoring equipment technology, and in particular to a gas emission filtration device for environmental monitoring, comprising a housing, a rotating filter assembly, a power assembly, and an impurity collection assembly. The housing has an air inlet and an air outlet. The rotating filter assembly contains multiple layers of concentric annular filter screens with gaps between the layers. The power assembly drives the filter screens to rotate. The impurity collection assembly is located below. Centrifugal blades are provided between adjacent filter screens to enhance impurity separation; a unidirectional flow assembly is provided at the air outlet to prevent gas backflow. The device increases the filtration area through multiple layers of filter screens, reduces clogging by rotating the filter screens, assists in impurity separation with centrifugal blades, and ensures unidirectional gas discharge through the unidirectional flow assembly. This device effectively solves the problems of easy clogging and low efficiency in existing filtration devices, achieving efficient and stable filtration, meeting environmental protection requirements, and is suitable for various gas emission scenarios.
