摘要:
This invention relates to a method and an apparatus for cleaning a flue-gas, which are applied in thermal engineering and in particular in thermal power plants and industrial enterprises with combustion installations. The apparatus for cleaning a flue-gas comprises horizontal absorber with absorption section (1) and gas-inlet conduit (5) on its one side, and outlet conduit (6) for cleaned gas, as in the lower end and longitudinal the absorption section (1) is implemented by areas (2.1, 2.2, 2.3, and 2.4) for solutions or suspensions. Between the individual areas (2.1, 2.2, 2.3, and 2.4) are located partitions (11), and at the end of the absorption section (1) separation section (3) and adsorption section (4) with outlet conduits (9.1, 9.2, and 9.3) are located next to each other. Absorption (1), separation (3) and adsorption (4) sections are mounted in a common housing (10), and inlet conduits (7.1, 7.2, 7.3, and 7.4) are provided to each zone (2.1, 2.2, 2.3, and 2.4 ) for supplying the absorbing agents in the relevant area, and outlet conduits (8.1, 8.2, 8.3, and.4) for product discharging after absorption. The outlet conduit (6) for cleaned gases is located after adsorption section (4).

The invention relates to an animal house ventilation system (1), in which animal house air, when passing horizontally through the system in a box (2), passes through a liquid mist, which may contain acid or base, and then passes through a droplet separator (4a and 4b), where the liquid in the air is precipitated by striking against droplet separators in the form of vertically mounted lamellae (9a and 9b), so that the liquid may be collected at the bottom of the box (2). The lamellae (9a and 9b) in the droplet separator may be provided with projections in the form of waves, bulges and the like in order to better form impact faces for the liquid in the air. Each droplet separator (4a and 4b) may be pulled out of the box; (2) via a door (3) with a view to cleaning by flushing for the removal of dust and feathers, etc. Following this, the cleaned droplet separators may be inserted into the box (2), and the door (3) is closed, and then cleaning may be resumed. This ensures simple and efficient cleaning, as the droplet separators may be cleaned easily.

A mercury capture system and method that includes the equipment for and the production of a mercury-sorbent metal sulfide in a flue gas conduit of a coal fired power plant. The system can include transition metal salt solution injection and sulfur solution injection apparati that can introduce transition metal salt solution and sulfur solution droplets (individually or as a co-injection) into the flue gas stream. The method can include the introduction (individually or as a co-injection) of a copper salt, an iron salt, and a sulfur compound into the flue gas stream, wherein the mercury-sorbent metal sulfide can be manufactured and reacted with mercury in the flue gas.

Systems and processes for reducing carbon capture emissions are described. The process involves introducing a radical species into a decarbonized combustion gas. The radical species react with residual amines or unwanted compounds in the decarbonized combustion gas, thus reducing the concentration of residual amines or unwanted compounds in the exhaust gas. The system includes a carbon capture absorber with non-thermal plasma generator configured to provide radical species reducing the concentration of residual amines or unwanted compounds in the exhaust combustion gas.

The invention relates to a system for trapping atmospheric emissions, made up of a liquefaction tank which contains a liquid that traps the dust, smoke or gas, which are injected into same through a main duct, to which the source of the emission to be trapped is connected, said duct including a first fan which operates by absorbing and propelling the dust, smoke and gas, guiding same into the liquefaction tank, said duct being sealed at the end thereof, the side walls of the duct comprising at least ten outlet openings, the invention also comprising a system with at least two walls with the same effect and perforations, thus causing the liquefaction of the trapped material; likewise, the invention comprises a cooling system, which guides the liquid from the tank into a serpent coil and from there to a pump which generates the recirculation of the liquid; at the top of the tank, the invention comprises an outlet duct via which the gases produced by liquefaction are guided into a compressor, which has the function of compressing the gases and injecting same into a first gas-storage tank.
