MULTIFUNCTIONAL DUST AND GAS CATCHER Russian patent published in 2007 - IPC B01D46/00 F24F7/00 

FIELD: chemical industry; other industries; production and usage of the dust-and-gas catchers.

SUBSTANCE: the invention is pertaining to the ventilation system and may be used for the deep purification of the being removed polluted air from the dust and gas up to the norm of the maximum permissible concentration (MPC), and also to the standardized high-speed, temperature and moist parameters. The dust and gas catcher contains the body divided into the chambers of the polluted and the clear air, the hopper, the local air suction, the stand-alone stimulator of the air draft. The outlet branch-pipe of the stand-alone stimulator of the air draft is made in the form of the diffuser, on which outlet there is one or several gaseous burners with the spray jets for delivery of water. If the quantity of the burners exceeds one, then the dissector is installed in the diffuser. As the stand-alone stimulator of the air draft use the disk ventilators or ejectors. The angle of turning of the body of the stand-alone stimulator of the air draft with the diffuser concerning the vertical axis can vary within the limits from 0 up to 90 degrees. The water for feeding in the spray jets can be aromatized. The dust and gas catcher allows to conduct purification of the removable air from the solid and gaseous components up to the norm of the maximum permissible concentration, the invention allows to keep the standardized parameters of the air within the limits of its speed, temperature and humidity, and also conducts the effective work in the recirculation mode. Multifunctional dust and gas catcher meets the ergonomical, sanitary-hygienic, ecological and economical requirements.

EFFECT: the invention allows to keep the standardized parameters of the air within the limits of its speed, temperature and humidity, to conducts the effective work in the recirculation mode and the multifunctional dust and gas catcher meets the ergonomical, sanitary-hygienic, ecological and economical requirements.
