Product Overview:
Ionization capture device, also known as ion air purifier, relies on a high-voltage electric field to ionize fine particles (such as smoke, dust, viruses, bacteria) in the air, forming ion clusters, and then capturing or removing them through physical or chemical reactions. Ionizing capture devices are widely used in the treatment of industrial waste gases such as chemical, coking, building materials, metallurgy, ceramics, and automobile exhaust.
System composition:
The ionization capture system consists of a spray tower, an electric capture tower, and an exhaust device.
1. Spray tower
It consists of a spray tower, a fire tower, a circulation system (water supply pump, circulation pump, backup pump, and circulation valve group, etc.), and a water gas separator.
2. Electric capture tower
Composed of an electric capture tower, power control cabinet, high-voltage silicon rectifier, etc.
3. Exhaust system
Composed of induced draft fan, chimney, etc.
Internal structure:
1.High voltage electrode
The main part of an ionization trap is the high-voltage electrode, which is composed of a pair of parallel metal plates with a gap in between. Under high pressure, air molecules are ionized into positive and negative ions, a process known as ionization effect.
2.Ion transport channel
The ions passing through the electrode will move along a specific channel, which is usually designed as a mesh or honeycomb to increase the contact area with the air.
3.Capture medium
At the end of the channel, capture media such as HEPA filters, activated carbon, or specialized adsorbent materials are usually installed, which can effectively adsorb and fix charged ions and non ionized particles.
4.Control and detection system
The ionization trap is also equipped with an intelligent control system inside, which is responsible for adjusting parameters such as voltage and flow rate, and can also monitor ion concentration and filtration effect in real time.
Working principle:
1.Collisions between ions and particles
Under the action of an electric field, large particles are settled by gravity, while small particles move towards the electrode due to the action of charges, forming an “electrophoresis” process to improve capture efficiency.
2.Physical and Chemical Interactions
The capture medium can physically adsorb particles, while materials such as activated carbon can remove certain harmful gases through chemical adsorption, further purifying the air.
3.Efficient and Low Energy
The ionization trap is driven by electricity and has lower energy consumption compared to mechanical filtration, and has strong adaptability to particle size ranges.
Maintenance and optimization:
In order to ensure the long-term stable operation of the ionization capture device, the capture medium should be cleaned regularly and the electrodes should be checked for wear. The purification efficiency of ionization capture devices is closely related to design parameters, and can be improved by improving channel structure, adjusting parameters, optimizing electric field strength, electrode shape and spacing, gas flow rate, etc.
