Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, in particular to an explosion-proof exhaust gas spray tower. Background Art

[0002] At present, in the waste gas treatment process, the waste gas needs to be sprayed, so a spray tower is used to spray the waste gas, and the working principle of the spray tower is divided into circulating water spray tower, alkali spray tower, and acid spray tower.

[0003] For example, a composite waste gas treatment spray tower disclosed in the authorization announcement number CN219848888U can recover the sprayed sodium hydroxide absorption liquid into the storage tank through the action of a water pump and a reflux pipe, thereby improving the recovery rate of the sodium hydroxide absorption liquid and saving the cost of waste gas treatment.

[0004] However, when the above-mentioned spray head recovers sodium hydroxide, since the sodium hydroxide will carry impurities in the exhaust gas, and there is no filtering and recovery mechanism, the sodium hydroxide will also carry more impurities for circulation during recovery, which may cause blockage during spraying. For this reason, we propose an explosion-proof exhaust gas spray tower. Utility Model Content

[0005] The purpose of the utility model is to provide an explosion-proof exhaust gas spray tower. By setting a filtering and recovery component, it is convenient to use the filtering component and the U-shaped pipe to filter the impurities in the recovered liquid to avoid the circulation of impurities. The cooperation of the U-shaped pipe and the collecting bottle can collect the impurities, thereby avoiding the clogging of the spray component by the impurities.
