Problems solved by technology

[0002] At present, in the industry, the discharge of ammonia nitrogen sewage is large and comes from a wide range of sources. The discharge of a large amount of ammonia nitrogen sewage into the water body not only causes eutrophication of the water body, causes the water body to be black and smelly, and even has a toxic effect on the population and organisms.
Ordinary spray towers have only one spray water distributor, and the spray effect is poor. Part of the ammonia nitrogen sewage cannot be absorbed by the filler, but flows down along the inner wall of the spray tower, resulting in incomplete blow-off of ammonia nitrogen and failure to achieve blow-off. The best effect, and the ammonia nitrogen sewage flows into the downstream sewage treatment process, causing a certain pressure on the downstream sewage treatment process

Embodiment Construction

[0009] Such as figure 1 As shown, the present invention is divided into the first packing area 2, the second packing area 3 and the water accumulation area 4 from top to bottom inside the tower body 1, and a spray cloth is installed horizontally above the first packing area 2. The water device 5 is installed horizontally between the second filling area 3 and the first filling area 2. The secondary spraying water distributor 6 is connected to the secondary spraying pipe 7 and the The secondary spray pump 8 is connected, the water inlet pipe 9 of the secondary spray pump 8 is connected to the bottom of the water accumulation area 4, and the air outlet 14 is respectively set on the side above the first filling area 2 and the second filling area 3. Fan ports 10 are arranged around the upper part of the area 4, inlets 11 and vent pipes 12 are respectively arranged on the bottom side, and the pipe body of the water outlet pipe 13 is inserted inside the water accumulation area 4, and...

Abstract

The invention discloses an ammonia-nitrogen-stripping secondary spraying tower. The ammonia-nitrogen-stripping secondary spraying tower is characterized in that a first filler region, a second filler region and a water collecting region are respectively inside the tower body from top to bottom, wherein a primary spraying water distributor is horizontally arranged above the first filler region; a secondary spraying water distributor is horizontally arranged between a second filler region and the first filler region; the secondary spraying water distributor is connected with a secondary spraying pump by a secondary spraying tube; a water inlet tube of the secondary spraying pump is connected with the bottom of the water collecting region; a draught fan interface is respectively arranged at the periphery of the water collecting region; one side of the bottom of the water collecting region is respectively equipped with a man hole and a blow-down tube; and the tube body of the water outlet tube is inserted inside the water collecting region. By virtue of the setting, the ammonia-nitrogen-stripping secondary spraying tower can carry out secondary spraying onto the ammonia-nitrogen wastewater to realize secondary stripping; and wastewater for the secondary spraying and stripping is directly from the tower body, so that wastewater ammonia-nitrogen stripping is more complete, and an ideal ammonia-nitrogen removing effect is achieved; and meanwhile, pressure of a next wastewater processing process is relieved.
