A treatment system to efficiently remove lead from dust contained in extracted cement kiln combustion gas while reducing facility and running costs. A treatment system 1 comprising: a probe 3 for extracting a part of combustion gas, while cooling it, from a kiln exhaust gas passage, which runs from an inlet end of a cement kiln to a bottom cyclone; a classifier 5 for separating coarse powder from dust contained in the combustion gas extracted by the probe 3; a wet dust collector 6 for collecting dust from the extracted gas containing fine powder discharged from the classifier 5; and devices 12, 13 for feeding sulfurizing agent for sulfurizing lead contained in the kiln exhaust gas to the wet dust collector 6, and others. From the sulfurizing-agent feeders 12, 13 are preferably added the sulfurizing agents to a circulation liquid tank 7 or a pump 9 for circulating slurry. The slurry obtained by the wet dust collector 6 is separated into froth including lead and tail side slurry including gypsum by a flotation facility 14, 17, 18.

A treatment system to efficiently remove lead from dust contained in extracted cement kiln combustion gas while reducing facility and running costs. A treatment system 1 comprising a probe 3 for extracting a part of combustion gas, while cooling it, from a kiln exhaust gas passage, which runs from an inlet end of a cement kiln to a bottom cyclone; a first classifier 5 for separating coarse powder from dust contained in the combustion gas extracted; a dust collector 7 for collecting dust from the extracted gas containing fine powder discharged from the first classifier 5; and a second classifier 8 for dividing dust discharged from the dust collector 7 into fine powder and coarse powder, and others. Since more lead is distributed on the fine powder side classified by the second classifier 8, lead can efficiently be removed without using chemicals and the like. The fine powder classified by the classifier 8 may be desalted by washing; high-lead-level cake obtained after the washing can be recycled; or salt water can be added to a cement mill. The coarse powder may be added to a cement grinding process or returned to cement material grinding process after the desaltation through washing.

The invention discloses a solar energy and air source heat pump linkage hot water system and a control method thereof. The system comprises a solar heat collector, an air source heat pump unit, a temperature preservation water tank connected with a system water-replenishing solenoid valve and a control system. The control method comprises the following procedures of: controlling a solar circulating water pump, controlling the system water-replenishing solenoid valve, controlling a circulating water pump of the air source heat pump unit and the air source heat pump system and controlling a user circulating water pump. With the solar energy and air source heat pump linkage hot water system and the control method thereof, the sufficient utilization of solar energy can be achieved, the operation of the air source heat pump unit is reduced as much as possible, the purpose of saving energy sources to maximum extent is achieved, and the demand of 24 h uninterrupted hot water for users is satisfied.

An automated rotary microtome blade changing apparatus, comprising an upper stage being adapted to releasably engage a supply cartridge and a waste cartridge, the upper stage having a loading segment adapted to engage and move blades contained within the supply cartridge into a cutting position; clamping means for releasably holding the blades in place for cutting operations; power means for driving the movement of blades and clamping mechanisms; and electronic control means for integrating all of the functions of the apparatus.

The invention relates to application of a low-carbon saving type pig house, belonging to the field of application of a pig house. The pig house adopts a galvanized steel pipe greenhouse structure, and the roof of the pig house is covered with a plastic light transmission film and a sun-shading net material; a ventilation opening which can be opened and closed is arranged on each of a south wall body and a north wall body, a retractable ventilation skylight facing toward the south is arranged at the top of the pig house and is pulled and retracted through a longitudinal scroll at the top of the pig house; a fan is arranged on each of an east gable and a west gable of the pig house for supplementing ventilation; and a medium pressure atomization spraying system is arranged above a pigpen inthe pig house, a fermentation bed is arranged on the south side of the interior of the pigpen, fermentation bed padding is laid in a fermentation bed padding pit, an aeration fermentation system pipeline is buried at the bottom of the pit. The pig house adopts steel pipe materials and the structure which is helpful for convection and ventilation, and utilizes time-delay atomization spraying technology, fermentation bed pig raising technology and the aeration fermentation technology at the bottom of the fermentation bed, so that the pig house reduces construction cost and use cost, is energy-saving and environment-friendly, and reduces carbon emissions.
