Ion exchange filters FIF, CF, FIF-CF is modern, high-efficiency gas-cleaning equipment for many purposes.
Air purification technology is based on the use in filters unique ion exchange fibers PANION®.
Air purification occurs due to chemical interaction between toxic pollutants and active groups of ion exchange material.
Construction of filters makes it possible to use them in exhaust, supply and recirculating ventilation systems in different branches of industry and agriculture.
Due to low air resistance the filters can be installed not only in designed projects, but also in al-ready existing ventilation systems.
|Capacity||500 – 100 000 m3/h|
|Total content of pollutants||1- 500 mg/m3|
|Temperature||+1 - +70 °С|
|Humidity of air flow||30-100 %|
|Content of water-insoluble dust not more, than||5 mg/m3|
The main competing technologies are biofilters and scrubbers. In comparison with them ion exchange filters have a range of undeniable advantages:
Filters are used in exhaust, input and recycling ventilating systems in various branches of industry and agriculture.
Extremely promising direction. Pig-breeding farms, poultry farms, cattle breeding farms.
Electrochemical and galvanic manufactures, shops, bays.
Chemical and chemico-metallurgical enterprises;
Manufacture of rare and noble metals and concentrates;
Manufacture of inorganic compounds (acids, alkalis, ammonia, soda, salts, chemical reactants for laboratories).
Meat-processing industry. Meet packing houses.
Storehouses with the freezing installations using as a coolant ammonia.
Of the enterprises of any profile using electrotransport.
Glass factories. Process of glass polishing.
The filter set consists of the filter body and the tank for preparation of solution. The filtering element with fibrous ion exchanger PANION®, is within the body. The filter body is equipped with flanges for input and output of air flow.
The filter body and tank are produced of corrosion-resistant polypropylene armed with steel construction.
Air purification occurs due to sorption of air flow with surface of ion-exchange fiber PANION®. The sorption rate on the fiber PANION® exceeds the sorption rate on ion exchange resins by two orders, which allows increasing sorption surface per unit volume of the filter manyfold, the aerodynamic drag is thereby reduced (Figure 1).
The regeneration of filtering elements is realized with solutions of generally available and cheap reagents, which are prepared and kept in tank. The regeneration solution circulates until saturation of the removing component. After that it as a neutral salt can be returned into production or be reclaimed (Figure 2).
In dependence of purpose of air purification ion exchange filters are divided by means of arrangement and operating principle:
The filtering element of FIF is a set of frames with fixed ion exchange fabric. Air flow is filtered through the material, the pollutants are chemically bonded with active centers of ion exchanger.
The difference between the frame (FIF) and contact (CF) filters is that in the latter case the absorption of toxic components occurs due to moving of air in plane-parallel channels, created with separating elements, and diffusing of absorbing components to active surface of element.
For purification of complex gas-air mixtures the filter FIF-CF is produced, that is combination of filters FIF and CF in one unit. The gas flow goes at first through the filter CF and then through FIF.
The irrigation time of filtering element by regeneration solution is corrected for each technological process during operation.
МThe most effective using of gas-cleaning equipment is achieved by means of timely turning on of necessary working regime (irrigation, washing, dosing etc.). So in dependence of the fact, by whom? where? and how? the filter will be operated, there are 3 types of control mode:
Each of 3 types of control modes has its advantages and disadvantages. All control modes have a certain basic configuration, which on customer’s request can be added or changed. Details can be read below.
|Type of control system||Advantages||Disadvantages|
|1. manual||1. low price||
||1. high price|
The installation requires space defined by dimensions of the filter. The service of the filter requires not less than 1 m distance from each side.
The filter should be placed in a room where the temperature is not below 0 °С.
