摘要:
A flue gas treatment apparatus has a flue gas inlet, a treated gas outlet downstream of the flue gas inlet, and a gas flow path therebetween. The flue gas treatment apparatus comprises a particulate removal device. A first heater is downstream of the particulate removal device. The first heater heats the flue gas to a first treatment temperature. A first catalytic converter is downstream of the first heater for eliminating at least some CO and SO2 from the flue gas. A second heater is downstream of the first catalytic converter for heating the flue gas to a second treatment temperature. A second catalytic converter is downstream of the second heater for eliminating at least some NOx from the flue gas. At least a first fan forces the flue gas from the flue gas inlet to the treated gas outlet.

A super-large scale photon capture bioreactor for water purification and aquaculture, includes a sealable three-dimensional room. Water ditches (2) are constructed in a circuitous way at each planar layer inside the three-dimensional room. The water ditches (2) in a same planar layer includes a water inlet (12) and water outlet (13). A plurality of filter units (4) are formed at intervals in water ditches (2) at each layer. Float-planted plants (5) are provided on water surface of each filter unit, aquatic animals (6) and microorganisms (7) are provided underwater, and plant growth illustrating lights (8) are arranged above the float-planted plants (5) at an adjustable height. A vane wheel (15) is arranged under a water outlet (13) of the water ditches (2) in an upper layer and is connected with the generator (16). A water inlet (12) of the water ditches (2) in a next layer is arranged under the vane wheel (15). Water to be purified is guided to a water inlet (12) at an uppermost layer. The photon capture bioreactor is characterized in low energy consumption, less occupied area, no pollution and clean production.

摘要:
A system for growing a plant (1) in an at least partly conditioned environment comprises a cultivation base (11) for receiving a culture substrate (3) with a root system (4) of the plant therein. Root temperature control means (12) are provided which are able and adapted to impose a predetermined root temperature on the root system, and lighting means (20,21,22) which are able and adapted to expose leaves of the plant to actinic artificial light. According to the invention leaf heating means are also provided, which are able and adapted to impose on the leaf of the plant a leaf temperature varying from an ambient temperature. In a method for growing the plant a carbon dioxide assimilation management of a leaf system of the plant is thus influenced, and a supply of actinic light, the root temperature and the carbon dioxide assimilation management are adapted to each other.
摘要:
A carbon nanotube production system is used for improving plant growth characteristics for a plant growing medium, for example soil in an agricultural field. The system includes an internal combustion engine, for example a tractor engine, which is arranged to combust a fuel mixture therein which includes a blend of fuels and additives including a carbon nanotube seeding material. The engine is operated in pyrolysis to produce exhaust emissions containing black carbon ultrafine and nano soot, for example by towing an agricultural implement across the agricultural field. At least a portion of the exhaust emissions is captured and conditioned to process the carbon soot into carbon nanotubes. The conditioned exhaust emissions and carbon nanotubes therein are then applied to the plant growing medium, for example by using the agricultural implement to incorporate the conditioned exhaust into the soil.
