Condensate Filter

The function of the condensed water filter is to filter out impurities in the condensed water to protect the equipment that reuses the condensed water. 

In the process of condensed water recovery, the condensed water will still be polluted due to factors such as unclean pipes, valves, and water tanks, and in the process of system operation. 

Due to the inevitable phenomenon of running, dripping and leakage in the factory, impurities, dust suspended in the air, and oil will also pollute the condensed water, so the filter in the condensed water reuse system is essential.

Due to the inevitable phenomenon of running, dripping and leakage in the factory, impurities, dust suspended in the air, and oil will also pollute the condensed water, so the filter in the condensed water reuse system is essential.

The technical problem to be solved by the utility model is: in order to solve the problem that harmful particles and oil in the condensate water recovery system are difficult to filter out and the condensate water recovery quality is low.

  • Condensate water filter, including liquid inlet device, filter container, and filter element arranged in the filter container.
  • The liquid inlet device has an inlet and an outlet, and the filter container has an inlet and a number of leaks.
  • Export one is connected with import two.
    The liquid inlet device is funnel-shaped. It is convenient for liquid to enter, and the inlet area of liquid is increased.
    The outer wall of outlet 1 is provided with external threads.
  • The inner wall of the second inlet is provided with an inner thread that matches the outer thread, and the first outlet and the second inlet are threadedly connected.
  • Threaded connection, easy to disassemble. The filter container includes a main body and a bottom, the main body is in the shape of a cylinder, and the bottom is in the shape of a truncated cone or a hemisphere.
  • In order to allow the liquid to enter the bottom faster, the bottom is shot into a frustum or hemisphere.
    The height of the filter element in the filter container is not lower than the maximum height of the leak hole.
  • If the height of the filter element is lower than the height of the leak hole, a part of the condensed water will flow out directly without the filter element, and it will not be able to filter.
  • The leak hole is a round hole or a diamond hole.

The new type of condensed water filter has high efficiency, low cost, simple structure, and good effect on removing harmful particles and oil.

Condensate iron removal filter is an energy-saving and environmentally friendly product developed to overcome the instability of iron ions in high-temperature condensate water.

It adopts a lightweight porous ceramic filter material composite iron removal integrated system to remove metal iron, copper, oil (hydrocarbon) organic matter and other pollutants in the condensate water, and solve the problem of the water quality of the condensate water.

The condensed water iron removal filter realizes the complete recovery of steam condensed water, saves energy and water resources, reduces environmental thermal pollution and noise when condensed water is discharged, and has great economic and social benefits.

Control system: It consists of control cabinet, pressure gauge and solenoid valve. (Automatic form can be made according to user needs)
Filtration system: It consists of filter container, filter material, air distribution parts, and valve.
Recoil system: It is composed of air source distributor, air compressor and air pipe fittings.


  • The iron removal rate is high.
    Equipment structure design and special treatment medium, high filtration precision (up to 1µm); in the application of iron removal in condensate water, the iron content in the filtered water can easily be reduced to below 0.05ppm.
  • Does not change water hardness.
    Porous ceramic filter material is used, due to the high sintering temperature, the filtration performance is stable, and there is no hardness precipitate.
  • The effluent quality is stable.
    Due to the advantages of the treatment mechanism and the high dirt holding capacity of the filter material, the system has strong impact resistance, and can maintain the stability of the filtration accuracy with only single-stage filtration when the concentration of suspended solids in the raw water changes greatly. And the iron content of the effluent can be reduced to 0.05ppm within ten minutes of normal operation after each backwash, and it remains stable throughout the filtration cycle.
  • High backwashing efficiency.
    Because the backwash water of the system cannot use tap water, and the softening water equipment of the boiler has a limited water production capacity. The system adopts the method and structure of point-by-point pulse gas-water composite backwashing, which greatly reduces the amount of backwashing water, increases the specific surface area of the filter material, and prolongs the backwashing cycle. The condensed recovery water to be filtered) can be backwashed to ensure the normal operation of the system.
  • Large interception capacity and long filtration cycle.
    This system uses an unshaped filter medium, which has a large specific surface area, strong adsorption capacity, and a higher dirt holding capacity than ordinary filters, which greatly prolongs the filtration cycle. When the iron content in the condensate system is above 6ppm on average, the filtration cycle is about 7 days, and when the average iron content is 2–3ppm, the filtration cycle is backwashed once every 14–21 days.
  • Low energy consumption for operation.
    a. Use normal pressure or low pressure filtration, without adding any new power device, thus greatly reducing the operating cost. b. Power consumption for backwashing: only 1-2 kWh/time; c. Water consumption for backwashing: less than 5% of the traditional method.
  • Small footprint.
    Meet most units are restricted by site conditions during project renovation. Therefore, the system can be combined in a modular manner, ranging from 0.1 tons to hundreds of tons per hour. The floor area is smaller than that of traditional equipment, and the system form can be individually designed according to the actual situation of the user.
  • Adopt PLC control automatic operation mode.
    In order to ensure the processing effect and reduce the problem of operation errors, the PLC control automatic operation mode is adopted. Users can connect with the existing central control system for real-time monitoring.
