Embodiment 1

[0021] See Figure 1~4 In the embodiment of the present invention, a dust removal waste gas treatment device includes a tank body 1, an atomizing nozzle 12, and a lift pump 14. The lower part of the tank body 1 is provided with a sedimentation chamber 2, which is a cone-shaped chamber. 2 is filled with absorption liquid; the precipitation chamber 2 is provided with an air outlet 3, and the air outlet 3 is provided with a circumferentially distributed air outlet branch pipe, so that the exhaust gas is evenly dispersed in the absorption liquid, and the absorption efficiency of harmful substances is improved; The upper end of the head 3 is connected with a central pipe 4, the central pipe 4 extends above the tank 1 and is connected with an intake pipe 6 through a rotary joint 5, and exhaust gas enters the central pipe 4 from the intake pipe 6.

[0022] The precipitation chamber 2 is provided with a stirring rod 7, which is fixedly connected to the central tube 4; the central tube 4 ...

Embodiment 2

[0025] The difference between this embodiment and the first embodiment is that a first partition 10 is provided above the sedimentation chamber 2, and a circumferentially distributed ventilation tube 11 is nested on the first partition 10, and the ventilation tube 11 is a cone. The opening diameter at the upper end of the vent cylinder 11 is larger than the opening diameter at the lower end of the vent cylinder 11; the vent cylinder 11 penetrates the first partition 10 and communicates with the precipitation chamber 2; the exhaust gas flows upward from the vent cylinder 11 after being purified by the absorption liquid; the vent cylinder 11 An atomizing nozzle 12 is arranged above, and the absorption liquid sprayed by the atomizing nozzle 12 meets the exhaust gas rising in the ventilation tube 11, so that the exhaust gas and the atomizing liquid are fully contacted, and the effect of absorbing harmful substances in the exhaust gas is further improved; 12 is fixedly connected to a...

Abstract

The invention discloses a dedusting waste gas treatment device. The device comprises a tank and atomizing sprayers; a precipitation cavity is formed in the lower portion of the tank, and a gas outlethead is arranged in the precipitation cavity; a first clapboard is arranged above the precipitation cavity, ventilation cylinders which are circumferentially distributed are embedded in the first clapboard, and the atomizing sprayers are arranged above the ventilation cylinders. According to the device, through the arrangement of a rotary stirring rod in the precipitation cavity, absorption liquidforms rotational flow, and precipitation of suspended matter is accelerated; meanwhile, through a shielding disc, a precipitate is prevented from being raised by the rotational flow; through the arrangement of the ventilation cylinders opposite to the atomizing sprayers, the absorption liquid collides with the front of waste gas, and the adsorption effect on atomizing liquid is improved.

Description

Technical field [0001] The invention relates to the field of waste gas treatment, in particular to a dust removal waste gas treatment device. Background technique [0002] Waste gas purification mainly refers to the treatment of industrial waste gas generated in industrial sites such as dust particles, smoke and dust, odorous gases, and toxic and harmful gases. Common waste gas purification includes factory soot and waste gas purification, workshop dust and waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc. Exhaust gas from industrial production often has harmful effects on the environment and human health. Purification measures should be taken before being discharged into the atmosphere to make it meet the requirements of exhaust gas emission standards. This process is called exhaust gas purification. Commonly used exhaust gas purification methods are: absorption meth...
