[0003] In the existing water spray dust removal device technology, the dust-containing tail gas is sent into the absorption tower by a fan and directly enters the spray area of the absorption tower.

[0024] As mentioned in the background art of the present application, through research, it is found that in the existing water spray dust removal device technology, the dust-containing tail gas is sent into the absorption tower by a fan and directly enters the spray area of the absorption tower. At present, the contact effect between the tail gas and the spray water mist can be improved by changing the movement mode of the tail gas. Although this spraying method can purify most of the dust in the tail gas, there is still some dust that does not come into sufficient contact with the sprayed water mist, resulting in an inefficient dust purification effect.

A waterproof housing 11 is fixedly connected to the position corresponding to the shaft rod 10 on the top end surface of the upper support plate 6, and a stepping motor 12 is fixedly connected inside the waterproof housing 11.

[0031] In this embodiment, the adjustable filtering mechanism specifically includes: a first frame 20 fixed to the bottom end surface of a lifting plate 19 and a second frame 21 fixed to the top end surface of another lifting plate 19.

In addition, when the adaptive adjustment component switches the working mode, the brush hairs on the strip plate can also brush the filter screens to further improve the cleanliness of the filter screens.
[0032] In this embodiment, the circulating drying assembly specifically includes: at least five storage plates 34 that are arranged side by side vertically and are movably connected in the storage cavity 33. A molecular sieve layer 36 is provided between two adjacent storage plates 34, and a square frame 35 is fixedly connected to the outside of the molecular sieve layer 36. A horizontal channel 45 is provided for communication between the storage cavity 33 and the adsorption cavity 5. At positions corresponding to the horizontal channel 45 on the inner walls of both sides of the adsorption cavity 5, limiting card rails 47 are fixedly connected.

One side surface of the storage box 32 is fixedly connected to a support frame 41, and the top surface of the support frame 41 is fixedly connected to a cylinder 42. At a position corresponding to the horizontal channel 45 on one inner wall of the storage cavity 33, a placement groove 43 is provided, and a vacuum suction head 44 is movably connected inside the placement groove 43. The vacuum suction head 44 is connected to an external negative pressure device.

A number of uniformly distributed slot holes are provided on the top surface of the storage plate 34, and lifting blocks 37 are symmetrically and fixedly connected to both side surfaces of the storage plate 34. At positions corresponding to the lifting blocks 37 on the inner wall of the storage cavity 33, lifting grooves 38 that match them are provided, and a lead screw 39 is rotatably connected inside the lifting grooves 38. At a position corresponding to the lead screw 39 on the top surface of the storage box 32, a lifting motor 40 is fixedly connected, and the bottom output shaft of the lifting motor 40 is fixedly connected to the lead screw 39. The lead screw 39 penetrates through the lifting block 37 and is threadedly connected to it. Through the provided circulating drying assembly in this application, not only can the molecular sieve layer 36 be sent into the adsorption cavity 5 to dry the purified tail gas, but also the molecular sieve layer 36 can be automatically replaced after being used for a period of time.
[0033] In this embodiment, on one side below the storage cavity 33, there is a heating cavity 48, and a heating wire 49 is provided inside the heating cavity 48. This setting can heat each molecular sieve layer 36 to desorb the adsorbed water molecules and restore its adsorption capacity for cyclic use.
[0034] In this embodiment, an air outlet pipe 50 communicating with the adsorption cavity 5 is fixedly connected to the top surface of the square adsorption tower 4. The air outlet pipe 50 is used to discharge the purified tail gas.
[0035] In this embodiment, a one-way valve 59 communicating with the water washing cavity 2 is embedded in the bottom end surface of the adsorption cavity 5. The one-way valve 59 enables the accumulated water in the adsorption cavity 5 to only flow into the water washing cavity 2.
[0036] In this embodiment, a water inlet 51 communicating with the water washing cavity 2 is fixedly connected to the other side near the edge of the top surface of the water tank 1. The water inlet 51 is used to supplement water into the water washing cavity 2.
[0037] The working principle of the present invention is as follows: When in use, first, the lowermost molecular sieve layer 36 is pushed into the adsorption chamber 5 by the circulating drying assembly. Specifically, the cylinder 42 operates to extend the output shaft, and the vacuum suction head 44 extends out from the placement groove 43 and abuts against the square frame 35 around the lowermost molecular sieve layer 36. As the output shaft of the cylinder 42 continues to extend, this molecular sieve layer 36 together with the corresponding square frame 35 is pushed along the horizontal channel 45 into the adsorption chamber 5 and is stuck in the limit card rail 47 in the adsorption chamber 5. In addition, during the process of the molecular sieve layer 36 passing through the horizontal channel 45, the infrared moisture sensor 46 detects the moisture content of the molecular sieve layer 36 and sends the detection result to the background control terminal. The background control terminal analyzes according to the detection result to judge whether there is an abnormality in the moisture content of this molecular sieve layer 36. If there is an abnormality, a warning is sent in time. Then, the exhaust gas containing dust from the outside is sent into the water washing chamber 2 through the air inlet pipe 3. After the exhaust gas enters the water washing chamber 2, due to the inertial effect, the large particle dust is wrapped and polymerized by water molecules and sinks into the water, and the gas phase overflows upward from the water and enters the adsorption chamber 5 through the air guide pipe 60.
[0038] After the exhaust gas enters the adsorption chamber 5, it first passes through the lower through hole 9 of the lower support plate 8, and then sequentially passes through three movement channels from bottom to top. At the same time, the water pump 13 operates to pump water from the water washing chamber 2 through the water inlet pipe 14 and send it to three horizontal water outlet pipes 16 through the vertical water outlet pipe 15, and finally sprays out from the spray head 17 and shoots into the three movement channels, which enables the exhaust gas to be dust-removed by spraying when passing through the movement channels. It should be noted that the adaptive adjustment assembly has two working modes. In the first working mode, the upper and lower exhaust gas movement channels become larger, and the middle exhaust gas movement channel uses a double filter screen. In this case, even if the dust and water mist do not contact sufficiently, the double filter screen can filter the dust more efficiently, thereby improving the dust purification effect. In the second working mode, the upper and lower exhaust gas movement channels become smaller, and the middle exhaust gas movement channel uses a single filter screen. In this case, the dust and water mist in the upper and lower movement channels are in full contact, improving the dust purification effect. At the same time, the sprayed water mist can also efficiently wash the two filter screens to improve the cleanliness of the filter screens to ensure the filtering effect. In addition, when the adaptive adjustment assembly switches the working mode, the bristles on the strip plate can also brush the filter screens to further improve the cleanliness of the filter screens. Among them, when the adaptive adjustment assembly switches from the second working mode to the first working mode, the water mist sprayed by the spray head 17 can wash the upper and lower exhaust gas movement channels, and the two enlarged exhaust gas movement channels are also convenient for the dust remaining in them to be washed and flow downward. During the use process, the two working modes are switched back and forth according to the preset program, thereby avoiding dust clogging the channels on the premise of ensuring full contact between the dust and the water mist, and effectively improving the final dust purification result.
[0039] The specific process of the working mode switch is as follows: the stepping motor 12 operates to drive the shaft rod 10 to rotate, the lifting plate 19 moves up and down along the threaded section 18 of the shaft rod 10, and the limiting block 57 moves along with the vertical limiting chute 58, thereby changing the height of each movement channel, that is, changing the size of the movement channel. At the same time, the first frame 20 and the second frame 21 have a relative displacement, the first strip plate 28 and the second strip plate 30 move along, and the first brush bristles 29 and the second brush bristles 31 respectively brush the second filter screen 23 and the first filter screen 22, while the first limiting slider 24 moves along the first limiting chute 26, and the second limiting slider 25 moves along the second limiting chute 27.
[0040] After the tail gas is secondary purified through the three movement channels, it passes through the upper through hole 7 of the upper support plate 6 and reaches the upper part inside the adsorption cavity 5. Subsequently, the tail gas passes through the molecular sieve layer 36 and is led out from the air outlet pipe 50. During this process, the molecular sieve layer 36 dries the tail gas. As time goes by, the molecular sieve layer 36 in the adsorption cavity 5 reaches the working limit, and the cyclic drying component replaces the molecular sieve layer 36 in the adsorption cavity 5 according to a preset program. Specifically: the external negative pressure device connected to the vacuum adsorption head 44 operates, so that the vacuum adsorption head 44 firmly adsorbs on the square frame 35. Subsequently, the cylinder 42 operates to retract the output shaft, and the vacuum adsorption head 44 pulls the square frame 35 together with the molecular sieve layer 36 back to the initial position along the horizontal channel 45. Immediately afterwards, the lifting motor 40 operates according to a preset program to drive the lead screw 39 to rotate, and the lifting block 37 descends a certain height along the lead screw 39 in the lifting groove 38, thereby causing each placement plate 34 and the molecular sieve layer 36 to move along. At this time, the second molecular sieve layer 36 from the bottom is aligned with the horizontal channel 45. Subsequently, the second molecular sieve layer 36 is sent into the adsorption cavity 5. And so on. When all the molecular sieve layers 36 reach the service limit, each molecular sieve layer 36 is retracted into the placement cavity 33, and then all the molecular sieve layers 36 are lowered to the lower part inside the placement cavity 33. At this time, the heating wire 49 in the heating cavity 48 operates to heat each molecular sieve layer 36, so that the adsorbed water molecules are desorbed and its adsorption capacity is restored, and the water molecules flow from the slot holes to the bottom of the placement cavity 33 and flow out of the placement cavity 33 through a reserved pipeline (not shown in the figure). Then, each molecular sieve layer 36 is sent into the adsorption cavity 5 from top to bottom in turn for use, and this cycle is repeated.
[0041] It should be noted that large-particle dust in the water washing chamber 2 settles to the bottom of the water washing chamber 2 under its own gravity and gathers in the rotating groove 52. The sediment discharging mechanism cleans the dust gathered in the rotating groove 52 at regular intervals according to a preset program. Specifically, the driving motor 55 operates to drive the rotating roller 53 to rotate counterclockwise by twenty degrees. During this process, the sealing plate 54 moves accordingly, and the dust gathered in the rotating groove 52 is transferred away by the sealing plate 54 and finally sent out through the inclined groove 56. This sediment discharging mechanism can slowly and orderly transfer the sediment away and seal the sediment during the transfer process to prevent the sediment from tumbling and causing secondary pollution, thereby improving the final dust purification result.
