Complete set of ammonia nitrogen stripping tower equipment

The complete set of ammonia nitrogen stripping tower equipment is processed with fiberglass or carbon steel anti-corrosion materials, which solves the problem of short service life caused by sewage corrosion in traditional equipment. Capable of treating wastewater of different concentrations, with high removal rate of ammonia nitrogen, and meeting the national discharge standard of ≤ 15mg/L after treatment.

Design principle explanation of complete ammonia nitrogen blow off tower equipment: The blow off method is used to remove ammonia nitrogen from water. Gas is introduced into the water, causing gas-liquid contact and allowing free ammonia dissolved in the water to pass through the gas-liquid interface and transfer to the gas phase, thereby achieving the goal of removing ammonia nitrogen.

Ammonia nitrogen in water mostly exists in a state of equilibrium between ammonia ions (NH4+) and free ammonia (NH3). In practical engineering, blow off towers are mostly used. The structure of the blow off tower adopts a gas-liquid contact device, which is filled with packing inside the tower to increase the contact area. After adjusting the pH value, water is sprayed onto the packing material from the top of the tower to form water droplets, which fall down through the gaps of the packing material and come into contact with the air blown up from the bottom of the tower by the fan in reverse flow, completing the mass transfer process and converting ammonia from liquid phase to gas phase. The ammonia is discharged with the air, completing the blow off process with a removal rate of over 75%.

Low concentration wastewater is usually blown off with air at room temperature, while high concentration wastewater is often blown off under heating. The blown off ammonia gas then enters the ammonia absorption purification tower, where it undergoes a chemical reaction with the absorption liquid, resulting in gas emissions that meet standards and are pollution-free.

The advantages of the complete ammonia nitrogen stripping tower equipment mainly include the following aspects:

1. Excellent corrosion resistance: Made of fiberglass material, it has excellent corrosion resistance and can resist various corrosive media such as acid and alkali corrosion, oxidation corrosion, etc. This enables the equipment to operate stably for a long time in the sewage treatment process, and is not easily corroded by sewage, thereby extending the service life of the equipment.

2. Environmentally friendly and pollution-free: During the process of removing ammonia nitrogen, the waste gas generated will enter the ammonia absorption system for treatment to ensure that the gas meets the emission standards. This avoids the secondary pollution problem that may be caused by the direct emission of ammonia into the atmosphere in traditional processes, making the entire treatment process more environmentally friendly.

3. Widely used in various fields such as medicine, pesticide and chemical industry, landfill, fertilizer production, coking industry, rare earth smelting, and domestic sewage treatment. Its excellent performance and wide application fields make the ammonia nitrogen stripping tower an important equipment in environmental protection and industrial fields.

4. Small footprint: Combining the tower body, absorption tank, circulation pump, and absorption pipeline system into a complete set of equipment with a compact structure, making it easy to install and operate on site. In addition, the use of high-density and low resistance fillers and liquid film infiltration technology further reduces the equipment's footprint and kinetic energy consumption.
