Problems solved by technology

However, since the temperature of the exhaust gas is about 170°C, the temperature is relatively high. After entering the spray scrubber, the water washing spray is easy to gasify, and a large amount of fine dust is taken away into the air, and the dust is adsorbed on the packing, which is easy to pollute the packing. Replace packing to maintain normal operation

Embodiment Construction

[0010] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the protection scope of the present invention.

[0011] The invention provides a waste gas treatment device used in the catalyst production process, which includes a saturator and a spray scrubber, and the spray scrubber is on the scrubber. A water inlet pipe is provided, and the water inlet pipe runs through the spray scrubber and extends into the saturator, and the water inlet pipe is provided with a nozzle at the part of the saturator and the spray scrubber; the saturator is used To cool down the waste gas discharged into it, and then discharge the waste gas into the spray scrubber; the spray...

Abstract

The invention provides a waste gas treatment apparatus used in a catalyst production process. The apparatus comprises a saturator and a spray washing tower, the spray washing tower is provided with a water inlet tube, the water inlet tube penetrates through the spray washing tower and extends into the saturator, and the portion of the water inlet positioned between the saturator and the spray washing tower is provided with a nozzle; the saturator is used for cooling waste gas discharged into the saturator, and then discharges waste gas into the spray washing tower; and the spray washing tower is used for washing and purifying the cooled waste gas discharged from the saturator. The saturator is used to cool the discharged waste gas, so gasification does not occur during water wash spraying in the spray washing tower, thereby the content of fine dusts into air is substantially reduced, the adsorption quantity of a filler in the spray washing tower is reduced, the replacement frequency of the filler is reduced, the cost is saved, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of catalyst production equipment, and in particular relates to an exhaust gas treatment device used in the catalyst production process. Background technique [0002] Usually, the catalyst production unit is divided into raw material slurrying, spray molding, roasting, washing, filtering, drying, receiving and other units. [0003] The waste gas from the spray drying tower contains fine dust, acid gas and other substances. The waste gas enters the spray washing tower for purification. The fine dust in the waste gas is absorbed by the filler, and the other part of the extremely fine dust and acid gas is sprayed with water. The drench settles to the bottom of the tower, and enters the sewage tank with the water for treatment. However, since the temperature of the exhaust gas is about 170°C, the temperature is relatively high. After entering the spray scrubber, the water washing spray is easy to gasify, and a l...
