3) biomembrane filled tower of organic matter class industrial waste gas, belong to the environmental protection equipment field.
Along with industrial expansion, waste gas and the foul gas day of containing various organic pollutions more increase, particularly contain benzene, toluene, polycyclic aromatic hydrocarbon, the waste gas of organic sulfur compound and organic chloride is the most serious to the pollution of health and ecological environment, studies show that, sucks low concentration (＜5g/m for a long time
3) toluene can cause slow poisoning, symptoms such as leucocyte minimizing contact the infringement that polycyclic aromatic hydrocarbons such as benzene, dimethylbenzene can cause liver, brain and kidney for a long time.For the processing of the organic exhaust gas of high concentration, because having it to recycle, the organic exhaust gas of high concentration is worth, at present successful processing modes such as existing absorption process, absorption method and catalytic combustion; (＜5g/m) the purification of industrial organic exhaust gas can not be ignored though handle its harm to environment, biology and health, and because of it does not have recovery value, and intractability is big, so that the present is still studied is less yet to low concentration.
The purpose of this utility model is a kind of packed tower that is used to purify and handle industrial organic exhaust gas of invention.
The purpose of this utility model is a kind of packed tower that adopts biomembrane processing and purifying industrial organic waste gas of invention.
The purpose of this utility model is that a kind of employing biomembrane of invention is handled or purifying low-concentration (＜5g/m
3) packed tower of industrial organic exhaust gas.
The purpose of this utility model is a kind of processing low concentration (＜5g/m of invention
3) during industrial organic exhaust gas, packed tower inside is placed with the surface and has the biomembranous packing ring of one deck at least.
The purpose of this utility model is the packed tower that a kind of biomembrane filled tower of invention inside has the filler baffle plate of one deck at least, preferably leaves the biomembrane filled tower for industrial waste gas purifying in certain interval space between every layer of filler.
The purpose of this utility model be a kind of packing ring that is positioned over biomembrane filled tower for industrial waste gas purifying inside of invention preferably below one deck packing ring more than top one deck filler, then from the bottom filling layer to the top packing layer, every layer of packed height is decline trend.
The purpose of this utility model is that a kind of shape of cross section with the biofilm packing ring of invention can be annular, waveform, square saddle type, M shape and irregular special-shaped shape, the shape of cross section of packed tower is circular, square, the biomembrane filled tower for industrial waste gas purifying of rectangle or other irregular shape shape.
The purpose of this utility model is finished by following array structure: biomembrane filled tower for industrial waste gas purifying,
It is characterized in that the packed tower bottom has a waste gas inlet and a liquid outlet pipe at least, top has a purified gas gas outlet at least, a liquid influent pipe is arranged at the top, water inlet pipe can be connected packed tower inside with nozzle one deck baffle plate at least, on every layer of baffle plate, can stack the biomembranous packing ring that has that quantity do not wait according to need, form packing layer; From packed tower bottom to the height each layer baffle plate of packed tower top for successively successively decreasing, the baffle plate of packed tower inside is preferably the 2-8 piece, on the every baffle plate several through holes should be arranged; Be positioned between packing ring on the baffle plate and the top one deck baffle plate certain interval (L) is preferably arranged; Liquid influent Guan Keyu at least one nozzle in packed tower top connects; Have biomembranous packing ring shape annular, waveform, square saddle type, M shape and irregular special-shaped shape, preferably annular; The tower body shape of biomembrane filled tower is circular, square, rectangle or other irregular shape shape.
During use, the bottom waste gas inlet of apparatus of the present invention biomembrane filled tower is joined with the industrial waste gas pipe that needs to purify, packed tower lower liquid delivery port and top liquid influent mouth are joined with water pump, with three blocks (or using polylith block) it is divided into three layers of packing layer (perhaps multilayer) in packed tower inside, in each layer packing layer, put into some packing rings, but the packing ring height that the bottommost packing layer is placed in the packed tower is the highest, the packing ring height that second layer packing layer is placed secondly, the packing ring height that the 3rd layer of packing layer placed is minimum; Each packing ring must have one deck biomembrane, but the shape Any shape of each packing ring; The shape of cross section of packed tower can be cylindrical, and is square or square; Several through holes are arranged on the every baffle plate, with guarantee to allow waste gas can from baffle plate by and directly contact with biomembrane in the packing ring.
One at the nozzle at packed tower top, also can be a plurality of, as long as can guarantee nutrient liquid evenly is showered into packing ring for best from packed tower top, therefore the nozzle in the biomembrane filled tower of the present invention can be the nozzle of the free rotational angle of energy, also can be the nozzle that directly is installed on the liquid influent pipe.
Discharge from the top again after needing purified waste gas to enter from the packed tower bottom, after nutrient liquid enters from top of tower again at the bottom of the tower leakage fluid dram discharge, waste gas and liquid two-phase are reverse flow in tower, organic matter in the waste gas is through the mixed liquid phase that enters of turbulent flow, and be attached that microorganism in packing ring surface biological film absorbs, degraded, purify, it is final that what discharge is Purge gas.
The nutrient solution that sprays in the tower mainly is to guarantee that the microorganism fungus kind in the biomembrane can be worked and survive effectively on the packing ring.
