VENTILATION WET DUST-CATCHER Russian patent published in 2006 - IPC B01D47/02 B01D53/18 

FIELD: chemical industry; textile industry; food industry; light industry; other industries; ventilation wet dust-catchers.

SUBSTANCE: the invention is pertaining to the devices of the ventilation wet dust-catching and may be used in chemical, textile, food, light and other industries for purification of the dusty gases. The dust-catcher contains: the body with the inlet branch pipe; the mounted on the body fan with the branch pipe for withdrawal of the purified gas; the drop catcher; the upper and lower partitions located in the body, on one of which there is the fixed water-baffle; the tank with the liquid and with the liquid level regulator; the device for the slime removal. On the lower partition place in the body, which is arranged in the tank with the liquid, there is the fixed vibrator. The ratio of the height "d" of the upper level of the water counting from the lower edge of the upper partition to the height "b" of the upper level of the water up to the surface of the maximum height of the water-baffle is in the optimal interval of the values: d/b = 0.3...0.5. The ratio of the height "d" of the upper level of the water from the lower edge of the upper partition to the distance "c" from the water level in the tank with the liquid to the lower edge of the upper partition is in the optimal interval of values: d/c =1.0...1.5. The vibrator is made in the form of the rectangle inscribed in the dimensions of the lower plate or is made in the form of the arranged with a certain pitch elements of the vibrator inscribed in the dimensions of the lower plate, and the ratio of the total length of the partitions «L» to the length of the apparatus "B" is in the optimal interval of the values: L/B = 0.65... 1.7. The invention ensures the increased efficiency and reliability of the dust catching process due to the greater surface of the gas-liquid suspension.

EFFECT: the invention ensures the increased efficiency and reliability of the dust catching process due to the greater surface of the gas-liquid suspension.
