Machine.
Preferably, outlet bend pipe be L shape pipe, and outlet bend pipe protrude into pond it is intracorporal it is open at one end downward.
Preferably, gauze is equipped on filter screen.
Compared with prior art, the beneficial effects of the present invention are:
1. the present invention using and the antipodal exhaust-gas treatment channel of existing bio-trickling technology, from the top of pond body into useless
Gas absorbs and carries by the indoor liquid bubble that froths, enter packing layer jointly, consumes, will give up by the strain of packing layer
Volatile organic matter and foul gas in gas exhaust and retain dust particles, obtained cleaning gas again under pond body part go out
Gas bend pipe returns in atmosphere；Waste gas flow direction and gas ascending path of the invention is on the contrary, to improve gas in packing layer
Residence time.
2. the present invention first forms the room that froths with liquid bubble, the specific surface area of one side liquid bubble is very big, promotes useless
Gas is contacted with liquid；On the other hand a large amount of gas-liquid foam is caused in packing layer 2, increase gas in the stop of packing layer
Between, the rejection of exhaust gas is substantially increased, to improve the treatment effeciency of exhaust gas.
3. the ingredient of what the present invention used froth liquid is water, fatty acid sodium salt, NaOH and white sugar, moisture guarantees the wet of filler
Degree, air promote the production of aerobic bacterium to make biofermentation products pure object pollute, and lye constantly consumes strain metabolism and produces
Raw acid product is to improve aerobic fermentation efficiency, and white sugar can provide certain organic nutrition source for strain, thus significantly
The production efficiency for improving strain, further increases the treatment effeciency of exhaust gas.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the novel exhaust-gas treatment bio-trickling filter of one kind proposed by the present invention；
In figure: 1 pond body, 2 packing layers, 3 filter screens, 4 liquid feeding tanks, 5 high speed bubbling machines, 6 Bubble blowing tubes, 7 air compressors, 8 outlets
Bend pipe, 9 filling openings.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1, the middle part of a kind of novel exhaust-gas treatment bio-trickling filter, including pond body 1, pond body 1 is equipped with packing layer
2, pond body 1 is divided into two parts, top up and down and is divided into the room that froths by packing layer 2, and lower part is divided into drip chamber, the lower section of packing layer 2
Equipped with filter screen 3, the bottom of 1 outer wall of pond body is communicated with liquid feeding tank 4, and liquid feeding tank 4 is communicated with high speed bubbling machine 5 by water pipe, high
Fast bubbling machine 5 is equipped with Bubble blowing tube 6, and Bubble blowing tube 6 passes through the side wall of pond body 1 and extend into the interior that froths of pond body 1；Pond body 1 froths
The top of room is connected to by tracheae in the outlet side of air compressor 7, and the inlet end and waste gas collection device of air compressor 7 connect
It connects；The side wall of 1 drip chamber of pond body is equipped with outlet bend pipe 8, and outlet bend pipe 8 is located at the lower section of filter screen 3；Packing layer 2 is specially height
Any one of water-absorbing resin, porous ceramics, diatomite and polyurethane cellular foam；Liquid feeding tank 4 is equipped with filling opening 9, filling opening 9
Equipped with sealing cover, filled with the liquid that froths in liquid feeding tank 4, froth water of the liquid by weight percent 85-95%, the sodium soap of 5-10%
Salt, the white sugar composition of the NaOH and 0-2% of 1-3%, one end that Bubble blowing tube 6 protrudes into pond body 1 is equipped with the porous mouth that froths, froths at a high speed
Machine 5 is specially electric bubble blowing device；The present invention first forms the room that froths with liquid bubble, and the specific surface area of liquid bubble is very big, with
Exhaust gas comes into full contact with and dissolves wherein water soluble organic substance, and exhaust gas and bubble pass through packing layer 2 simultaneously under the influence of air pressure；It blows
Bubble pipe 6 be continuously packing layer 2 provide moisture, air, froth liquid and lye, moisture guarantee filler humidity, air promotion have
The production of oxygen bacterium to make biofermentation products pure object pollute, lye constantly consume acid product that strain metabolism generates from
And aerobic fermentation efficiency is improved, on the one hand the liquid that froths promotes exhaust gas to contact with liquid, on the other hand cause in packing layer 2 a large amount of
Gas-liquid foam, increase gas in the residence time of packing layer, substantially increase the rejection of exhaust gas, to improve exhaust gas
Treatment effeciency.
With reference to Fig. 1, it is equipped with gauze on filter screen 3, soaks the impurity in rear adsorbable surplus liquid, the liquid that avoids frothing is recycling
The adverse effect of high speed bubbling machine 5 and Bubble blowing tube 6 is blocked since solid impurity is excessive in the process.
With reference to Fig. 1, outlet bend pipe 8 is L shape pipe, and outlet bend pipe 8 protrude into pond body 1 it is open at one end downward, prevent out
