Biological Drip Filtration Deodorizing Equipment

Determination of process parameters

1. Pump selection

2. The height of the packing is about 0.8-1.2M

3. Ventilation speed

The gas residence time in the equipment is 5-25 seconds (the empty tower residence time of our equipment is generally more than 20 seconds)

The ventilation linear velocity is controlled at 0.2M/S=0.5M/S. (The empty tower gas velocity is the linear velocity of the mixed gas calculated based on the empty tower cross-sectional area. The tower bottom gas volume is the largest, and is generally calculated based on the tower bottom gas volume;)

Our equipment uses spherical polymer organic fillers, D = 50MM, (void ratio) = 0.73

The effective volume and height of biofiltration and biofiller should be calculated according to the following formula: V=QT/3600 H=VT/3600

Where: V—Effective volume of packing layer (M³)

Q—Odor flow rate (M³/h)

T—empty tower residence time (S)

H—packing layer height (m)

V—empty gas velocity (m/s)

Performance advantages of biological deodorization

● High treatment effect and good deodorization effect
  Microbial filtration deodorization equipment can effectively remove specific pollutants such as hydrogen sulfide, ammonia, methyl mercaptan, etc., with good deodorization effect and deodorization efficiency of more than 95%. It can meet the most stringent deodorization and environmental protection requirements in different regions in any season and any climate adjustment.

  The deodorization process is advanced and reasonable
  . The final emissions are harmless to humans and animals. It is an environmentally friendly technology with no secondary pollution.

● In the initial stage of operation of the microbial activity
  equipment, only a small amount of nutrients need to be added. The microorganisms can always be in a good active state by absorbing nutrients in the exhaust gas.

● Large impact load resistance capacity
  can automatically adjust the peak value of waste gas concentration, so that the microorganisms always work normally, and have strong impact load resistance. This is the most unique and advantage of the spray-microorganism filtration deodorization equipment compared with other methods.

● Biological seasoning has a long life.
  The biological filler made through special processing has the characteristics of large specific surface area, easy formation and fall of biofilm, corrosion resistance, biodegradation resistance, good thermal insulation performance, high porosity, low high loss and good air and water distribution. The service life can reach 8-10 years.

● The equipment is easy to operate and does not
 require special personnel to manage or daily maintenance. It is easy to manage and has extremely low operating costs. It can run continuously for 24 hours and is also suitable for intermittent operation. There are few vulnerable parts and maintenance management is very simple.

● Automatic control, fully automatic operation
The fully automatic control can be controlled remotely or locally, and has two control modes: manual and automatic. The process operation is fully automatic according to the settings, and the operation is very stable. It basically realizes unmanned management and does not require manual operation. Workers only need to patrol.

● The overall or modular assembly
is convenient for transportation and installation. When increasing the odor treatment capacity, only components need to be added. It is easy to implement and also convenient for separate treatment under gas source conditions.

● Low pressure loss and low energy consumption.
Since the filler has good structural stability and air permeability and a long service life, the equipment has low pressure loss and low operating energy consumption.

● Low operating costs
Only a small amount of electricity is required during operation. The annual electricity cost of conventional equipment is between 6,000 and 18,000 yuan depending on the size.

With the continuous exploration and improvement of biological deodorization technology, and based on the unique advantages of this equipment, its application prospects in the treatment of organic waste gas (VOCS) in urban sewage treatment plants and chemical and pharmaceutical industries are becoming more and more extensive.

Only a small amount of nutrients needs to be added in the initial stage of equipment operation. The microorganisms can always be in a good active state by absorbing nutrients in the exhaust gas.
