Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
First embodiment
As shown in fig. 1, the present embodiment provides a bio-trickling filter apparatus 100, which includes an infrared analyzer 110 and a plurality of trickling filters 120. The plurality of trickling towers 120 are connected to the infrared analyzer 110 through a plurality of individual first pipes 130, respectively. Each first pipeline 130 is provided with a first electromagnetic valve 131, and the first electromagnetic valve 131 is in communication connection with the infrared analyzer 110.
First, the exhaust gas is introduced into the infrared analyzer 110, the infrared analyzer 110 absorbs different radiation energies according to the concentration difference of the gas to be purified in the exhaust gas, the remaining radiation energy causes the temperature rise in the detector to be different, and the pressures on both sides of the moving plate film are different, thereby generating an electrical signal of the capacitance detector. In this way, the concentration of the components in the exhaust gas can be measured indirectly. And then the waste gas is sequentially introduced into different trickling filters 120 according to the concentration of each component to be removed in batches. Waste gas can be removed more accurately, waste of raw materials is reduced, and time is saved.
The exhaust gas passes through the infrared analyzer 110 and then enters the corresponding first pipe 130. The infrared analyzer 110 is connected to the first electromagnetic valve 131 of the first pipeline 130 in a communication manner, and when the infrared analyzer 110 detects the exhaust gas, the detected information is transmitted to a central control system (not shown), and the central control system controls the corresponding first electromagnetic valve 131 to open, so that the exhaust gas enters the corresponding trickling filter tower 120.
Referring to fig. 2, each trickling filter tower 120 includes a tower body 121, a packing assembly 140, a spray assembly 150 for spraying a nutrient solution, and a lift assembly 160 for lifting the packing assembly 140. The spray assembly 150, the packing assembly 140 and the lifting assembly 160 are all arranged in the tower body 121, and the packing assembly 140 is connected with the lifting assembly 160.
The exhaust gas enters from the side of the trickling filter tower 120 near the bottom. Waste gas adopts the mode of countercurrent to promote the time of waste gas circulation, increased its contact time with the nutrient solution, and then promoted the effect of absorbing of microorganism to the interior material of waste gas.
Further, the spray assembly 150 includes 3 spray headers 151, and the 3 spray headers 151 are disposed at the top in each tower body 121. After the waste gas enters the tower body 121, the waste gas moves from bottom to top, and meanwhile, the spray header 151 is opened to start spraying the nutrient solution. The waste gas contacts with the sprayed nutrient solution, and the components in the waste gas are absorbed or dissolved by the nutrient solution and then fall on the packing component 140 to be absorbed or degraded by the microorganisms on the packing component 140 to obtain purified water, and meanwhile, the microorganisms grow and reproduce.
The number of the showerheads 151 may be appropriately selected according to the production requirements and the size of the trickling filter tower 120, and is not limited to 3 in the present embodiment. Meanwhile, in order to increase the probability of the nutrient solution contacting the exhaust gas, the shower head 151 may be designed as a rotatable shower head 151.
Referring to fig. 2 again, further, the packing assembly 140 includes 5 packing elements 141, and the 5 packing elements 141 are sequentially arranged from top to bottom. The lifting assembly 160 includes 8 lifting members 161, and two opposite lifting members 161 are fixedly connected to the edge of each packing member 141.
After entering the trickling filter 120, the exhaust gas sequentially passes through the packing elements 141 from bottom to top. The packing member 141 is a mesh support having a plate-like structure with the same shape and size as the horizontal interface of the tower body 121. The plate-shaped structure is provided with through holes or a net-shaped joint in the vertical direction so that exhaust gas can smoothly flow through. The filler may be directly placed on the surface of the filler member 141 or may be attached to the surface of the filler member 141. It can promote the area of contact of packing with waste gas, simultaneously, can not obstruct gaseous circulation, guarantees exhaust purification's efficiency and speed.
Preferably, the upper surface of the packing element 141 can be further provided with a plurality of protrusions 143, and each protrusion 143 can also be attached with a packing and a corresponding microorganism, so that the contact area between the waste gas and the packing is further increased, the contact time between the nutrient solution and the packing is prolonged, and the waste gas purification efficiency is improved. Preferably, the protrusions 143 are disposed at positions corresponding to the meshes of the net support, to facilitate contact of the exhaust gas with the packing. Meanwhile, a plurality of small holes may be formed in the protrusion 143 to increase the flow rate of the gas.
It should be noted that the protrusion 143 may be disposed on the lower surface of the packing member 141, or both the upper surface and the lower surface may be disposed with the protrusion 143. The shape of the protrusion 143 may be semicircular, triangular, or other geometric shapes.
Preferably, the particle diameter of the filler covered by the surface of the filler member 141 is sequentially decreased in the direction in which the gas flows. Since the concentration of the gas to be purified is high immediately after the exhaust gas enters the trickling filter 120, a filler having a large particle size is used in order to ensure that the exhaust gas contacts the filler as much as possible. And along with the contact of waste gas with nutrient solution, filler, the gas that needs to purify in the waste gas is absorbed the utilization by the microorganism gradually, and then leads to its concentration to reduce, in order to guarantee that it can be absorbed, degraded completely, reduces the particle size of filler and increases the quantity of filler to guarantee that it can be purified completely. At this time, the filler having a small particle diameter is used in order to achieve more accurate purification.
It should be noted that the number of the packing elements 141 can be increased or decreased according to the production requirement, and the packing elements 141 can also adopt other structures with through holes, or be a thin film made of a high polymer material and capable of simultaneously flowing gas and retaining macromolecular liquid while passing small molecular liquid. At this time, the nutrient solution can not be concentrated on the packing member 141 through the film, so that the concentration of the nutrient solution on the packing member 141 is increased, the propagation of microorganisms is promoted, the demand of the microorganisms on waste gas is increased, and the waste gas treatment capacity is increased. The purified water flows into the bottom of the tower body 121 and is directly collected to obtain clean water, so that the subsequent water purification process is reduced, and the production cost is reduced. The filler used and the microorganisms are suitably selected according to the composition of the exhaust gas to be purified.
Two opposite elevating members 161 are provided on the edge between the two packing members 141. Two elevating member 161 set up relatively and have guaranteed the stability of filler 141 for the filler 141 atress is more even, reduces the possibility that filler 141 took place to incline, and then makes the nutrient solution distribute more evenly, guarantees that the waste gas homoenergetic through filler 141 can fully contact with the nutrient solution, has promoted exhaust purification's effect.
Further, the elevating member 161 is fixedly connected to the packing member 141, and the packing member 141 is elevated as the elevating member 161 is elevated. Each lifting member 161 is a scissor lift, the construction of which is described in detail in CN 202924677U. When the lifting piece 161 rises, the packing element 141 rises along with the lifting piece 161, and after the lifting piece 161 reaches a preset working position, the lifting piece 161 stops rising, at the moment, the lifting piece 161 can also support and fix the packing element 141, so that the packing element 141 is prevented from sliding downwards, and the stability of the packing element 141 is ensured. When the filler needs to be replaced, the lifting element 161 is lowered, the filler elements 141 are lowered, and all the filler or the filler elements 141 can be replaced only at one replacing opening. The operation height of replacing the filler or the filler part 141 each time is reduced, so that the safety of operators is ensured, and the filler is more convenient to replace. Meanwhile, the range of use of the trickling filter tower 120 is increased.
Preferably, since the trickling filter tower 120 contains nutrient solution and microorganisms, which have a corrosion effect on the surface of the lifting member 161, in order to prolong the service life of the lifting member 161, a layer of corrosion-resistant and oxidation-resistant material may be attached to the surface of the lifting member 161, or the lifting member 161 is directly made of corrosion-resistant and oxidation-resistant material.
Further, in order to improve the supporting effect of the elevating member 161 on the packing member 141 and the stability of the packing member 141, the number of the elevating members 161 may be increased appropriately, but the elevating members 161 are both paired and disposed opposite to each other to ensure the stability of the packing member 141. Meanwhile, the distance between two adjacent packing elements 141 can be set to different distances according to different production requirements.
Further, the purified exhaust gas flows out of the trickling filter tower 120 through an outlet of the trickling filter tower 120. At this time, a part of water vapor is still in the exhaust gas, and in order to prolong the service life of subsequent equipment, the exhaust gas is dried and then detected, whether the gas with the highest concentration in the exhaust gas is purified or not is detected, and if the gas is purified, the gas is introduced into another trickling filter 120 to purify another gas component or is directly discharged.
Further, the nutrient solution flows to the bottom of the trickling filter 120 from top to bottom by spraying of the spray header 151, so as to obtain and store pure water. The bottom of the trickling filtration tower 120 is provided with through holes. In the process of water storage, the plug or other equipment is used to block and seal the water storage tank, so as to prevent the purified water from flowing out, and when the water liquid is accumulated to a certain degree, the plug or other equipment is pulled out, so that the purified water flows out of the trickling filter tower 120.
Above-mentioned biological dripping considers the device and can purify according to each gaseous concentration in the waste gas in turn, has promoted biological dripping and has considered device specificity and practicality, promotes purification efficiency through setting up a plurality of trickling filters. The biological dripping filtration device is simple in structure, convenient to operate and convenient for later maintenance.

Preferably, each of the spray headers 153 is inclined toward the top of the tower body 121, and the nutrient solution sprayed from the spray headers 153 disposed between the adjacent packing members can completely cover the lower packing member 141 of the two adjacent packing members 141.
