Embodiment Construction
[0016] Example figure 2 As shown, a biological filtration deodorization device includes an air inlet pipe 7, a centrifugal fan 5, an exhaust chimney 6 and a biological filtration tower. The biological filtration tower adopts a double-tower structure of a circular inner tower 1 and an outer tower 2. The inner tower is equipped with PP plastic packing, and the outer tower is a layered combination of PP plastic packing and inorganic-organic mixed packing. An annular air distribution channel 3 is arranged on the upper part of the inner tower 1, and an annular air collecting channel 4 is arranged on the upper part of the outer tower 2, and the slit-type air outlets are evenly arranged on the circumference of the air distribution channel and the air collecting channel; The inner and outer towers mentioned above are communicated through the lower space. The air inlet pipe 7 is connected to the annular air distribution duct 3 of the biological filter tower; the air duct connected to...

The invention provides a biological filter deodorizing device, which comprises an air inlet pipe, a biological filter tower, a centrifugal fan and an air discharge chimney. The device is characterized in that: the biological filter tower adopts a double-tower structure of circular inner and outer towers; the inside of the tower is filled with inorganic-organic mixed fillers; the upper part of theinner tower is provided with a ring-shaped air distribution channel; the upper part of the outer tower is provided with a ring-shaped air collection channel; the circumferences of the air distribution channel and the air collection channel are evenly provided with slotted type air outlets; the inner tower and the outer tower are communicated with each other by a lower part space; the air inlet pipe is communicated with an air inlet of the biological filter tower and the ring-shaped air distribution channel on the upper part of the inner tower; and an air inlet of the centrifugal fan is communicated with an air outlet of the biological filter tower and the ring-shaped air collection channel on the upper part of the outer tower, and an air outlet of the centrifugal fan is communicated with the air discharge chimney. The centrifugal fan pumps the biological filter tower, and a negative pressure is formed, thereby solving the problem of uneven air distribution and easy leakage of air existing in the prior device. The device also has the advantages of high removal rate, no secondary pollution, simple structure and convenient maintenance and management.
Description
technical field [0001] The invention relates to a deodorizing device, in particular to a biological filtration deodorizing device, which is used for the treatment of malodorous gas produced in the sewage treatment process in the field of environmental protection. Background technique [0002] At present, biological deodorization devices commonly used in the sewage treatment process, as shown in the attached manual figure 1 As shown, it is composed of a centrifugal fan 1, an air supply pipe 2, a prewash tank 3, a biological filter 4, and a discharge pipe 5 connected in sequence. Its working principle is that after being collected by the collection pipe, the malodorous gas is sent to the top of the pre-washing tank 3 by the centrifugal fan 1 through the air supply pipe 2, passes through the biological packing layer from top to bottom, and then enters the biological filter from the lower space, down to the bottom. It passes through the biological filler layer, and finally is d...
