Detailed implementation manners

[0029] The following further elaborates on the present utility model Figures 1-5 in conjunction with the appended drawings.

[0030] Please refer to the accompanying drawings of the specification Figures 1-5 for an embodiment provided by the present utility model: An alkali spray type waste gas treatment device, including a device main body 1 and a filter screen 11. An air inlet 2 is provided on the left side of the device main body 1, an air outlet 3 is provided above the device main body 1, a first fixing rod 5 is connected inside the device main body 1, and a first baffle 4 is fixed by the first fixing rod 5 to ensure its stability. The first baffle 4 is connected inside the first fixing rod 5, and a rotating rod 7 is connected to the outside of the first baffle 4. The movable block 6 is driven to move through the rotating rod 7 to facilitate the automatic descent of the solution. The rotating rod 7 is connected to the movable block 6 on the other side. A second fixing rod 9 is also connected inside the device main body 1, and a second baffle 8 is fixed by the second fixing rod 9 to ensure its stability. The second baffle 8 is connected below the second fixing rod 9, and a spray port 10 is connected below the second baffle 8. The waste gas treatment work is realized by spraying the solution through the spray port 10;

[0031] A storage groove 13 is connected to the center of the filter screen 11. The waste solution is filtered through the cooperation of the filter screen 11 and the storage groove 13. A support block 12 is provided below the filter screen 11, and an opening and closing door 14 is provided on the upper right side of the filter screen 11. The filter screen 11 can be quickly taken out through the opening and closing door 14 for replacement. A circulation pipe 15 is provided on the lower right side of the filter screen 11, and the other side of the circulation pipe 15 is connected to a liquid storage tank 16. The waste solution is temporarily stored and discharged through the liquid storage tank 16, and at the same time, the new solution is temporarily stored. A liquid inlet pipe 17 is connected above the liquid storage tank 16.

[0032] Refer to the accompanying drawings of the specification Figures 1-5 wherein, the first fixing rods 5 are evenly and equidistantly distributed around the first baffle 4. The first baffle 4 is in an "eight" shape, and the connection mode of the first fixing rod 5 and the device main body 1 is hot melt connection. The first baffle 4 is fixed by the first fixing rod 5 to ensure the stability of the first baffle 4.

[0033] Refer to the accompanying drawings of the specification Figures 1-5, the connection mode between the rotating rod 7 and the first baffle 4 is a rotating connection. A torsion spring is fixedly connected between the rotating rod 7 and the first baffle 4. The rotating rod 7 and the movable block 6 are integrally installed. There are four groups of movable blocks 6 in total. Through the cooperation of the rotating rod 7 and the movable block 6, the solution can flow downward, and at the same time, the waste gas is prevented from flowing upward through the movable block 6.

[0034] Refer to the attached drawings of the specification Figures 1-5 , the second baffle 8 is in an inverted "V" shape. The second baffle 8 is integrally installed with the device main body 1 through the second fixing rod 9. Spray nozzles 10 are evenly and equidistantly distributed below the second baffle 8. By cooperating the second baffle 8 with the first baffle 4, the residence time of the waste gas inside the device main body 1 is prolonged.

[0035] Refer to the attached drawings of the specification Figures 1-5 , receiving grooves 13 are evenly and equidistantly distributed in the center of the filter net 11. The filter net 11 is in a "V" - shaped structure. The connection mode between the filter net 11 and the device main body 1 is a sliding connection. Through the cooperation of the filter net 11 and the receiving grooves 13, the particles in the waste gas solution are filtered out to prevent them from blocking the circulation pipe 15.

[0036] Refer to the attached drawings of the specification Figures 1-5 , the connection mode between the support block 12 and the device main body 1 is a hot melt connection. The support block 12 and the filter net 11 are staggered. Connection keels are arranged on both sides of the filter net 11. The support block 12 is used to fix the filter net 11, which is convenient for quickly disassembling the filter net 11 for waste treatment later.

[0037] Working principle: When in use, first, the waste gas is introduced into the interior of the device main body 1 through the air inlet 2. At the same time, the circulation fan blades inside the air outlet 3 are turned on to adsorb the waste gas from the bottom upward. Then the waste gas is preliminarily treated by spraying through the spray nozzles 10 below the first baffle 4, and then enters below the second baffle 8 along the center of the first baffle 4 and drifts toward both sides of the second baffle 8, and is sprayed again by the spray nozzles 10. At the same time, the solution accumulates toward the position of the movable block 6 along the upper part of the first baffle 4, flushing the upper part of the first baffle 4. When the solution accumulates too much and is greater than the elastic force of the torsion spring, the movable block 6 starts to rotate through the rotating rod 7, so that the waste solution drops downward. Then the torsion spring drives the movable block 6 to reset, preventing the untreated waste gas from moving upward through the movable block 6;

[0038] As described above, when the solution drops downwards, it drops above the filter net 11. The waste gas particles in the solution stay above the filter net 11 and fall into the interior of the storage tank 13 when moving towards the center along the filter net 11. After long-term use, open the opening and closing door 14, pull the filter net 11 upwards to disengage it from the support block 12, and then take out the filter net 11 to remove the sundries in the storage tank 13. The filtered solution enters the waste liquid tank on the left side of the liquid storage tank 16 through the circulation pipe 15 and is finally discharged.

[0039] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
