  • Patent number: 11982442
    Abstract: Disclosed is a system and method for the combustion of biomass material employing a swirling fluidized bed combustion (SFBC) chamber, and preferably a second stage combustion carried out in a cyclone separator. In the combustion chamber, primary air is introduced from a bottom air box that fluidizes the bed material and fuel, and staged secondary air is introduced in the tangential direction and at varied vertical positions in the combustion chamber so as to cause the materials in the combustion chamber (i.e., the mixture of air and particles) to swirl. The secondary air injection can have a significant effect on the air-fuel particle flow in the combustion chamber, and more particularly strengthens the swirling flow, promotes axial recirculation, increases particle mass fluxes in the combustion chamber, and retains more fuel particles in the combustion chamber. This process increases the residence time of the particle flow.

  • Patent number: 11981592
    Abstract: A biological nitrogen removal method based on multistage feeding and anoxic/aerobic chambers for adopting a constant flow operation mode, enabling wastewater subjected to primary treatment to enter a first-stage and a second-stage A/O reaction units from two position points; lifting and refluxing an effluent to an influent end of the first-stage units; lifting and refluxing an effluent to an influent end of the second-stage units; and clarifying, separating and discharging an effluent from an outlet end of a third-stage A/O reaction unit. The wastewater treatment mode combines a process based on two-stage wastewater feeding and three-stage anoxic/aerobic chambers with biofilms in different reaction zones, =optimizing and controlling a reflux ratio of each segment according to an amount of organic matters available for denitrification in influent, reducing the impact of hydraulic loading at the cross section in the reactors while removing organic matters and nitrogen-containing pollutants at a low temperature.

The shelf contains a product and has a movable gate to hold the product on the shelf. The delivery cup moves vertically along the vertical lead screw and has a solenoid and a plunger. The solenoid activates the plunger, which opens the gate to dispense the product onto the delivery cup. An outer door of the delivery area isolates the delivery area from outside the vending machine when closed and provides access to the product from outside the vending machine when open. A mechanical interaction between the delivery cup and the delivery area opens the outer door.
