In order to pre-filter the exhaust gas in the deodorizing tower, in one embodiment, please refer to fig. 2 and 3 together, the filtering device 200 further includes a pre-filter driving member 270, a pre-filter circulating pipe 280, a pre-filter spraying pipe 290 and a plurality of pre-filter spraying nozzles 291, the pre-filter driving member 270 is disposed on the tower body 100, one end of the pre-filter circulating pipe 280 is communicated with the pre-filter water tank 260, one end of the pre-filter circulating pipe 280 is communicated with an input end of the pre-filter driving member 270, the pre-filter spraying pipe 290 is disposed in the tower body 100, the pre-filter spraying pipe 290 is communicated with an output end of the pre-filter driving member 270, each pre-filter spraying nozzle 291 is disposed on the pre-filter spraying pipe 290, each pre-filter spraying 291 is communicated with the pre-filter spraying 290, and a space is disposed between two adjacent.
As described above, each of the pre-filter nozzles 291 is located above the multi-surface ball filler layer 222, so that the spray area of each of the pre-filter nozzles 291 can cover the surface of the multi-surface ball filler layer 222, and the chemical solution sprayed from the pre-filter nozzles 291 can uniformly permeate into each of the places in the multi-surface ball filler layer 222.
Next, in practical application, when the exhaust gas needs to be prefiltered, the prefilter driving member 270 draws the prefilter chemical liquid in the prefilter water tank 260 through the prefilter circulation pipe 280 and pressurizes and injects the prefilter chemical liquid into the prefilter spray pipe 290, the prefilter chemical liquid in the prefilter spray pipe 290 is sprayed out through the prefilter spray head 291, and then the prefilter chemical liquid gradually permeates into the surfaces of the multi-surface balls of the multi-surface ball filler layer 222.
Further, in order to spray the pre-filtering chemical solution onto the multi-surface ball packing layer 222 more uniformly, referring to fig. 2 again, the pre-filtering nozzles 291 are circumferentially distributed around the central axis of the pre-filtering water tank 260.
Thus, it should be noted that each pre-filter nozzle 291 is located above the multi-surface ball filler layer 222; each pre-filtering nozzle 291 is arranged above the multi-surface ball packing layer 222 in a manner that the central axis of the pre-filtering water tank 260 is circumferentially distributed, which is equivalent to that the spraying range of each pre-filtering nozzle 291 is also arranged above the multi-surface ball packing layer 222 in a manner that the central axis of the pre-filtering water tank 260 is circumferentially distributed, so that the spraying range of each pre-filtering nozzle 291 is more uniform as far as possible to spray the pre-filtering liquid medicine onto the multi-surface ball packing layer 222, each multi-surface ball in the multi-surface ball packing layer 222 can form a stable and reliable liquid medicine film, further, waste gas can be fully pre-filtered when passing through the pre-filtering component 220, and finally, the waste gas purification efficiency of the deodorizing tower is improved.

Thus, it should be noted that, in the practical application process, in the process that the exhaust gas enters the tower body 100 along the inner wall of the air inlet pipe 400, the exhaust gas horizontally entering the air inlet pipe 400 gradually has a downward inclination movement trend under the guidance of the bending part 410, and finally the exhaust gas entering the tower body 100 is accumulated in the pre-filtering water tank 260, and along with the gradual increase of the exhaust gas molecules, the exhaust gas gradually rises and passes through the pre-filtering assembly 220 for pre-filtering, so that the exhaust gas can pass through the pre-filtering assembly 220 at a lower flow speed, thereby prolonging the pre-filtering time of the exhaust gas, and further improving the exhaust gas purification efficiency of the deodorizing tower.
In addition, it should be noted that, when waste gas is accumulated in the pre-filtering water tank 260, the pre-filtering liquid medicine in the multi-surface ball packing layer 222 can also be dripped into the pre-filtering water tank from the flow guide vent hole on the guide plate 221, along with the dripping of the pre-filtering liquid medicine, part of particulate matters in the waste gas can be dripped into the pre-filtering water tank 260 under the carrying of the pre-filtering liquid medicine, thereby avoiding the excessive particulate matters attached to the multi-surface ball packing layer 222, the filler in the primary bio-packing layer 241 and the secondary bio-packing layer 251, further avoiding the particulate matters from damaging the liquid medicine film in each filler layer of the particulate matters, reducing the waste gas purification pressure of the deodorization tower to a certain extent, and improving the waste gas purification efficiency of the deodorization tower.
In order to further maintain the activity of the biofilm on the surface of the bio-filler in the primary bio-filler layer 241 and the secondary bio-filler layer 251, please refer to fig. 2 and 3 together, the horizontal bio-deodorization tower 10 further includes a nutrient adding device 500, the nutrient adding device 500 includes a nutrient preparation box 510 and a nutrient delivery pump 520, the nutrient preparation box 510 and the nutrient delivery pump 520 are respectively disposed on the tower body 100, an input end of the nutrient delivery pump 520 is communicated with the nutrient preparation box 510, and an output end of the nutrient delivery pump 520 is communicated with the spray pipe 340.

To reduce nutrient consumption, referring again to fig. 3, nutrient delivery pump 520 is a metering pump.
Therefore, it needs to be explained that the metering pump has higher pumping precision, so that workers can flexibly adjust the spraying concentration of the nutrient according to the requirements of actual application conditions, and the excessive nutrient is prevented from being sprayed under the condition that the purification pressure of the deodorization tower is lower.
In order to solve the problem that excessive impurities are easily accumulated at the bottom of the circulation tank 320, please refer to fig. 2 again, in one embodiment, the spraying device 300 further includes a blowdown assembly 360, the blowdown assembly 360 includes a blowdown pipe 361 and a blowdown valve 362, the blowdown pipe 361 is communicated with the circulation tank 320, and the blowdown valve 362 is disposed on the blowdown pipe 361.
Thus, it should be noted that, when the impurities at the bottom of the circulation box 320 need to be discharged, the liquid medicine in the circulation box 320 can be discharged out of the tower body 100 only by opening the drain valve 362, the impurities at the bottom of the circulation box 320 can be discharged out of the tower body 100 along with the liquid medicine, so as to prevent the bottom of the circulation box 320 from accumulating too many impurities, and further prevent the impurities from being discharged out of the tower body 100

Thus, it should be noted that, when the level of the liquid medicine in the circulation tank 320 is too high, the liquid medicine is directly discharged out of the tower body 100 along the bypass pipe 363, and the liquid medicine passing through the bypass pipe 363 can be discharged out of the tower body 100 without passing through the blowoff valve 362, so that the excessive liquid medicine can be prevented from being accumulated in the circulation tank 320, and the liquid medicine can be prevented from overflowing from the circulation tank 320.
