Product Description
Acid mist purification tower ZHT-I/II
     Acid mist purification tower ZHT-I/II is applied for purifying hydrochloric acid gas, sulfuric acid gas, nitrogen oxides (particularly suitable for difficultly absorbed nitrogen oxides) in electroplating pickling plant and other production processes.
      Purification process of acid mist purification tower ZHT-I/II: from upper purification body sprays alkaline absorption liquid. Acidic harmful gas goes into the lower part of the tower and contacts with absorption liquid by counter-current flow. Trough new efficient and low resistant filler and perforated tray in the tower the gas and liquid have a full contact to get a good purification effect.
 Acid mist purification tower ZHT-I/II has the following advantages:
    1. Using hard PVC plate or fiberglass material: light weight, easy processing, corrosion resistance.
    2. The composite combination structure of new high efficient filler and perforated trays: low resistance of equipment, high and stable purification efficiency.
    3. The energy-saving axial flow nozzle: large spraying fluid volume, low pressure of spraying liquid, small power consumption.
4. The use of sub-composite structure: easy to transport and install; the combination of the tower sections can be freely rotated; inlet and outlet direction can be adjusted; flexible installation.
Main technical Specifications:
ZHT-I/II purification tower purification efficiency η: for nitrogen oxides η≈80%; for hydrochloric acid and sulfuric acid mist η≥90%.
Seven specifications of ZHT-I series purification tower. Each specification is divided into type A (top wind) and type B (horizontal wind). When air quantity is within 2000 ~ 18500m³/h, the device resistance is ≤ 70 mm water column, front pressure nozzle of spray system is ≥10 m water column. Please refer to the following table for the details.
Purification tower components:
Gas outlet, Demisting segment, Spray section, Filler segment, Perforated plate segment, Toxic gas inlet, Pressure gauge, Fluid Pump, Fluid Tank

Note1. Fan model is based on the purification resistance (70 mm water column) and ventilation pipe resistance. The user can choose other types of fan according to the actual situation.
2. The pump model is selected according to the front nozzle pressure (≥10 m water column). The user can also choose other types of pumps.

Installation of purification tower series ZHT:
Purification system consists of two parts: ventilation and spray.
Ventilation system: including purification tower body, tower bracket, fan, ventilation ducts and other components.
Two installation types of purification tower:  
Type A (Press-in type): Fan outlet connects to purification tower air inlet. Ensure there is sufficient height at the installation site.
Type B (Suck-out type): Purification tower air outlet connects to fan inlet. It is suitable for restricted installation height at the installation site.
Spraying system: including tank, pump, spraying pipes, pressure gauge, valves and other components.
Tank is placed in the lower part of purification tower. If the device needs to be installed indoors in cold areas, connect the liquid inlet at the top of the tank and liquid outlet at the bottom of purification tower with lengthened pipe, but elevation of tank's top must be lower than the elevation of purification tower's bottom.
If the whole purification device is installed indoors and there is not enough height for the device, the tank may be installed in the pit or in the half-pit.
Tank should be installed at a height of about 100 mm on the platform. The platform surface should be flat and firm to ensure that the tank bottom is forced uniformly.
Four steel columns of tower bracket need to be pouring with concrete foundation. Pre-embedded anchoring bolts should fasten to the bottom plate.
Ventilation pipe and spraying pipe, connected to the purification tower, need a single set of hanger separately. Design the separate foundation for the ventilation and pump system according to the actual size of the device.
Take necessary sunshade measures during outdoor installation of purification tower with hard PVC plates.
Fix with cables if the height of the outlet at the top of the purification tower is more than 5 meters.
Fan and pump installation locations in the first and second drawings are for reference. Users can adjust the location according to the actual situations or use other forms of arrangement.

                                   A type                                                                                B type                                    

Operation and maintenance
Before operating the purification system first calibrate the air quantity within the allowable range, adjust shunt valve of the spray pipe in order to make the liquid ejection amount of the two stages nearly equal. During the operation start the pump first and then start the fan. When turning of the device, the operation steps are on the contrary.
The absorption liquid is generally ~5% sodium hydroxide solution for purification hydrochloric, sulfuric, and other acid mists. For purifying nitrogen oxides use 5% sodium hydroxide plus 2-4% sodium sulfide solution.
According to the length of the production cycle and the natural loss of circulating fluid, regularly check the alkalinity and add new fluid.
