Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, in particular to an alkali solution spray tower for sludge treatment. Background Art

[0002] The alkali liquid spray tower is a device used for waste gas treatment. It uses the differential contact countercurrent operation principle and corrosion-resistant fillers as the basic components for gas-liquid two-phase contact. The gas enters the tower body from the bottom of the tower, passes through the filler layer from bottom to top, and finally is discharged from the top of the tower. The alkali liquid is evenly sprayed onto the filler through the liquid distributor from the top of the tower, and flows down along the surface of the filler until it is discharged from the bottom of the tower.

[0003] In the existing technology, the alkali solution spray tower includes a spray tower, a spray head installed inside the spray tower, fillers, and a water pump. The water pump draws out the alkali solution and sprays it through the spray head to treat the gas in the spray tower. Although it has a treatment effect, when the amount of waste gas input is large, it is necessary to increase the height of the spray and extend the contact time of the alkali solution with the waste gas to achieve a better treatment effect. However, in this case, the cost of increasing the height of the spray tower needs to be invested, which occupies a large space and is not conducive to promotion and use. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, one of the purposes of the utility model is to provide an alkali solution spray tower for sludge treatment. Through the circulating pipe, circulating fan, external pipe and input fan, the exhaust gas after the initial spraying can be circulated for a second time into the interior of the spray tower body, so that secondary treatment can be carried out. Even if the amount of exhaust gas is large, it can still be completely treated, and the cost of increasing the height of the spray tower is saved. It occupies a small space and is easy to use. The observation container is set up to intuitively observe the internal situation of the water tank, which is convenient for timely adding alkali solution.
