Referring to fig. 1 and 2, the present invention provides a spiral trickling filter 100 with a screen plate, comprising a tower body 110, wherein a plurality of spiral chambers 111 are arranged in the tower body 110, as shown in fig. 3, an air inlet 114 and a discharge outlet 115 are arranged at the bottom of the tower body 110, an air outlet 116, a liquid inlet 119 and a top cover 150 are arranged at the top of the tower body 110, and the air outlet 116 and the liquid inlet 119 are both arranged on the top cover 150. Further, a plurality of spiral chambers 111 are arranged in parallel and uniformly in the tower body 110.
Preferably, as shown in fig. 4, the top cover 150 is further provided with a plurality of feed inlets 151, the plurality of feed inlets 151 correspond to the tops of the plurality of spiral chambers 111 one by one, and a feed inlet cover 152 for closing the feed inlets 151 is disposed on one side of the top cover 150 away from the spiral chambers 111. The purpose of providing the plurality of feeding ports 151 and the feeding port covers 152 is to avoid lifting the top cover 150 when filling the spiral chamber 111, and to directly lift the feeding port covers 152 for direct filling, which makes the filling more convenient. In this embodiment, one of the plurality of inlet openings 151 shares one opening with the air outlet 116, but of course, in other embodiments of the present invention, the remaining inlet openings 151 of the air outlet 116 may be separately provided.
When the spiral trickling filter 100 with the sieve plate works, the feeding port cover 152 is opened, the filling material which can be attached and grown by microorganisms is filled in the spiral cavity 111, nutrient solution which provides nutrient substances for the microorganisms enters the tower body 110 from the liquid inlet 119, waste gas enters from the bottom of the spiral cavity 111 through the gas inlet 114, and when the waste gas passes through the spiral cavity 111, the waste gas is treated by the microorganisms attached in the filling material and is then released out of the tower body 110 from the top of the spiral cavity 111 through the gas outlet 116. Because the spiral chamber 111 is spiral, the spiral chamber has certain obstruction effect on the discharge of gas, the time for treating the waste gas by microorganisms is prolonged, and the components in the waste which need to be removed can be treated more completely.
In addition, the internal filler of the spiral trickling filter tower 100 with a sieve plate is polluted after long-term operation, so that the treatment effect is reduced or disappears, the filler needs to be replaced, and the filler is discharged through the discharge hole 115.

The spiral nutrient solution spraying pipe 112 is arranged in the spiral cavity 111 and is used for providing nutrient substances required by growth for microorganisms in the spiral cavity 111 so as to ensure that the microorganisms in the filler can keep activity and growth, and therefore, the waste gas can be continuously and efficiently treated; the spiral nutrient solution spraying pipe 112 is formed in a spiral shape so as to be matched with the shape of the nutrient solution spiral chamber 111 to uniformly supply the sprayed nutrient solution.
Further, referring to fig. 2 again, in the present invention, the number of the nutrient solution spiral spraying pipes 112 in the spiral chamber 111 is at least 2, and at least 2 nutrient solution spiral spraying pipes 112 are uniformly disposed on the inner wall of the tower body 110 corresponding to the spiral chamber 111. In this embodiment, the quantity of nutrient solution spiral spray pipe 112 is 5, and 5 nutrient solution spiral spray pipes 112 evenly set up on the inner wall that tower body 110 corresponds spiral cavity 111 to make can be simultaneously comprehensive spray each department of filler with the nutrient solution, make the microorganism homoenergetic in the filler obtain nutrient substance fast effectively, in order to reach best activity and growing state. The purpose of all setting up a plurality of nutrient solution spiral spray pipes 112 in every spiral cavity 111 is to ensure that the microorganism that distributes everywhere in spiral cavity 111 can both obtain nutrient substance, and then improves the treatment effeciency of spiral utensil sieve plate trickling filter tower 100 to waste gas.
It should be noted that in other embodiments of the present invention, the number of the spiral nutrient solution spraying pipes 112 can be adjusted to more than 2 according to the actual engineering requirement. Of course, in other embodiments of the present invention, the number of the spiral nutrient solution spraying pipes 112 may be 1, but the treatment effect on the exhaust gas is relatively poor compared to when the number is more than 2.
Further, referring to fig. 5, a plurality of spraying holes 113 are uniformly formed along the length direction of the spiral nutrient solution spraying pipe 112. The purpose of this design is that it further ensures that the microorganism in spiral cavity 111 can both evenly and fully acquire nutrient to make nutrient solution evenly sprayed to every department of the packing in spiral cavity 111 simultaneously to reach better exhaust-gas treatment effect.
Further, referring to fig. 2 and 4, a high pressure sprayer 120 is disposed at the top of the tower body 110, and the high pressure sprayer 120 is communicated with the liquid inlet 119.

When feeding, the packing enters the spiral chamber 111 from the central position of the annular liquid distribution pipe 122. The nutrient solution spiral spraying pipe 112 is communicated with the high-pressure sprayer 120 through the annular liquid distributing pipe 122, and the problem that when the nutrient solution spiral spraying pipe 112 is directly connected with the high-pressure sprayer 120, the filler cannot smoothly enter the spiral cavity 111 due to the blocking of the nutrient solution spiral spraying pipe 112 at the top of the spiral cavity 111 is avoided.
When the spiral trickling filter 100 with the sieve plate works, nutrient solution enters the tower body 110 from the liquid inlet 119 and is sprayed out through the spraying holes 113 on the nutrient solution spiral spraying pipe 112 under the action of the high-pressure sprayer 120, and the sprayed nutrient solution has high water pressure, so that the nutrient solution can reach the area in the middle of the filler, and the biological matter attached to the filler can further ensure to obtain enough nutrient so as to further enhance the treatment effect of waste gas.
Meanwhile, when the spiral trickling filter tower 100 with the sieve plate stops working and the filler needs to be discharged to clean the spiral cavity 111, the filler is firstly discharged from the spiral cavity 111, then the cleaning water is introduced into the high-pressure sprayer 120 from the liquid inlet 119, and the cleaning water is sprayed out through the spraying holes 113 on the nutrient solution spiral spraying pipe 112 after being pressurized to clean the spiral cavity 111.
