Gas purifying device

Abstract

The invention discloses a gas purifying device which is simple, practical, lower in cost, and wide in application range, and can be used for purifying different waste gases. The gas purifying device comprises an outer tower, a backflow device and a liquid inlet pipe, wherein a gas outlet is arranged at the upper part of the outer tower, the bottom of the outer tower is provided with a liquid storing cavity, a gas dividing net is arranged above the liquid storing cavity, and a purifying cavity is formed between the gas dividing net and the liquid surface of the liquid storing cavity; the tail end of the backflow device is connected with the gas dividing net; one end of the liquid inlet pipe is communicated with the liquid storing cavity, the other end of the liquid inlet pipe is embedded into the backflow device, and the liquid inlet pipe is provided with a cone-hopper-shaped liquid outlet end; the gas to be purified enters into the backflow device under the action of a fan, and the purifying liquid in the liquid storing cavity flows along with the liquid inlet pipe under the action of a circulating pump, so that the gas which is sprayed out of the liquid outlet end and is guided to enter into the backflow device downwards moves in an acceleration way, and flows into the liquid storing cavity through the gas dividing net, therefore, a first circulating system can be formed; and the gas downwards moves along with the backflow device, is evenly filtered by the gas dividing net, and is evenly sprayed to the purifying cavity and sufficiently reacted with the purifying liquid to be purified, and the purified gas is discharged from the gas outlet through a hollow cavity arranged between the outer wall of the backflow device and the inner wall of the outer tower.

Description

technical field [0001] The invention relates to a gas purification device. Background technique [0002] Public canteens and restaurant catering kitchens will produce harmful exhaust gas that will produce a large amount of volatile oil and impurities during cooking. The direct discharge of this oil exhaust gas will cause serious environmental pollution and harm human health. This grease exhaust gas will produce scaling in the exhaust duct It is easy to cause fire hazard. The existing electrostatic deoiling technology is expensive, the effect is unstable, cleaning is inconvenient, the operating cost is too high, the burden on users is too heavy to accept, it cannot meet the national energy saving requirements, and it is not conducive to wide application. The general wet electric deoiling device is not effective and cannot meet the national environmental protection industry emission requirements. Contents of the invention [0003] Aiming at the deficiencies of the prior ar...
