Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a sludge drying and incineration waste gas collection and treatment device. Background Art

[0002] The flue gas produced by sludge drying and incineration contains a large amount of harmful substances such as acidic gases, nitrogen oxides, particulate matter, heavy metals, etc., which are harmful to human health. In order to treat these pollutants, an alkali spray tower is generally used to absorb the acidic substances in the exhaust gas into an alkaline solution, thereby reducing the acidity in the gas. The packing ball is an important component of the spray tower. The surface of the packing ball has a large surface area and voids, which can increase the contact area of ​​the gas or liquid in the packing bed, thereby improving the mass transfer efficiency. It can increase the contact time and contact area between the gas or liquid and the packing, and promote the mass transfer and reaction process of the substance.

[0003] The invention patent with patent number CN116272327A discloses an acid-base waste gas purification spray tower, which belongs to the field of waste gas treatment technology, including a waste gas tower, a waste water tank is installed at the lower end of the waste water tank, a water tank is installed at the lower end of the waste water tank, an air outlet pipe is installed at the upper end of the waste gas tower, an activated carbon filter layer is installed at the upper end of the waste gas tower, a double-headed motor is installed on the upper end side of the waste water tank, an exhaust gas purification mechanism is installed on one side of the double-headed motor, and a waste water purification mechanism is installed on the other side of the double-headed motor. An electromagnetic valve is installed at the lower end of the interior of the waste gas tower, a water pump is installed on the side of the water tank, a liquid inlet pipe is installed on the upper end of the water pump, and a liquid infusion pipe is installed at the other end of the liquid inlet pipe inside the waste gas tower. The invention sets an exhaust gas purification mechanism, which can drive the filter blade to rotate through the double-headed motor, and then cooperate with the water sprayed from the nozzle to filter and purify the exhaust gas, thereby avoiding the problem of exhaust gas being directly discharged outdoors, thereby affecting the atmospheric environment.

[0004] However, since the packing balls in the exhaust gas spray tower can be easily worn out gradually with the increase of working time, it is difficult for the staff to judge whether the packing balls in the tower are worn to the extent that they can no longer be used. Therefore, it is necessary to regularly inspect and clean the packing balls inside the spray tower. In addition, due to the movement of exhaust gas from bottom to top, the exhaust gas contacts the packing balls at the bottom first, which can easily cause the packing balls at the bottom of the tower to wear the most severely. The packing balls from bottom to top form a wear stratification, which greatly reduces the effect of the packing balls at the bottom, while the packing balls above cannot be in a relatively intact state. Not only does the effect of the top packing balls be blocked by the bottom packing balls, but the severely worn packing balls at the bottom will also hinder the contact between the exhaust gas and the spray liquid, resulting in a series of problems such as reduced exhaust gas purification efficiency of the tower and unstable pressure inside the tower.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-10An embodiment of the present invention is as follows: a sludge drying and incineration waste gas collection and treatment device comprises a spray tower 1, a first arc-shaped baffle 2 is slidingly provided on the side wall of the spray tower 1, a ventilation duct 8 is provided on the side wall of the spray tower 1, a fan 7 is fixedly provided on the end of the ventilation duct 8, a second arc-shaped baffle 13 is provided on the side wall of the spray tower 1, two support plates 3 are provided on the side of the spray tower 1, a rotating mixing mechanism 4 is fixedly provided on the top of the two support plates 3, three support mesh plates 10 are fixedly provided inside the spray tower 1, a spray pipe 11 is fixedly provided at the bottom of the three support mesh plates 10, a plurality of spray heads 12 are provided at the bottom of the three spray pipes 11, four resistance springs 9 are fixedly provided on the top of one of the support mesh plates 10, a closing mechanism 5 is fixedly provided inside the spray tower 1, and a detection mechanism 6 is provided on the side wall of the spray tower 1. First, the exhaust gas is output to the bottom of the spray tower 1 along the ventilation pipe through the fan 7, and then the spray liquid is sprayed out from the spray head 12 through the spray pipe 11, and the spray liquid circulates between a number of seasoning balls. Then, the acidic components inside the exhaust gas are purified by contact between the exhaust gas and the spray liquid. As the working time increases, the filler balls at the bottom are worn, and the severely worn filler balls fall from the gaps between the closing mechanisms 5 to the inside of the closing mechanisms 5 until the weight of the closing mechanisms 5 compresses the resistance spring 9, so that the closing mechanisms 5 drive the detection mechanism 6 to engage, and the detection mechanism 6 drives the closing mechanism 5 to rise while the closing mechanism 5 seals the severely worn filler balls inside. Then, the first arc baffle 2 is opened, and the closing mechanism 5 is driven to rotate and mix the filler balls inside the spray tower 1 while the rotating mixing mechanism 4 is inserted, and the closing mechanism 5 and the unusable filler balls inside are taken out. After the hollow closing mechanism 5 is flipped and reset, the second arc baffle 13 is opened, and then the closing mechanism 5 is inserted into the spray tower 1 and reset.

[0030] Specifically, the closing mechanism 5 includes a first arc plate 51, a plurality of cross bars 52, two second arc plates 53, a connecting plate 54, a plurality of fixed columns 55, a plurality of limit plates 56, a plurality of hollow rods 57, a plurality of wedge plates 58 and a plurality of triangular counterweights 59. The first arc plate 51 is fixedly arranged on the inner side wall of the spray tower 1, a plurality of cross bars 52 are fixedly arranged on the side wall of the first arc plate 51, two second arc plates 53 are slidably arranged on the inner side wall of the spray tower 1, the connecting plate 54 is fixedly arranged between the two second arc plates 53, a plurality of hollow rods 57 are fixedly arranged on the side walls of the two first arc plates 51, a plurality of fixed columns 55 are respectively arranged on the inner bottom of the corresponding hollow rods 57, a plurality of limit plates 56 are respectively fixedly arranged on the tops of the plurality of fixed columns 55, a plurality of triangular counterweights 59 are respectively slidably sleeved on the corresponding fixed columns 55, and a plurality of wedge plates 58 are respectively slidably inserted on the two side walls of the corresponding hollow rods 57. The second curved plate 53 is moved upward so that the wedge plate 58 abuts against the cross bar 52, so that every two adjacent wedge plates 58 move inwardly. The wedge plate 58 moves inwardly to close the top of the hollow plate, preventing the damaged filler balls inside the hollow rod 57 from falling back into the spray tower 1. When the wedge plate 58 needs to be reset, the second curved plate 53 and the hollow rod 57 are inverted, so that the triangular counterweight block 59 moves downward along the fixed column 55, so that the inclined surface of the triangular counterweight block 59 abuts against the wedge plate 58, so that the wedge plate 58 is separated again, which is convenient for the subsequent reinstallation of the damaged filler balls; when the damaged filler balls are taken out, the top of the hollow rod 57 is automatically closed to prevent the filler balls from falling back into the spray tower 1, without the need for electric control closure, and the wedge rod at the top of the hollow rod 57 can be automatically opened by inversion, which is simple to operate, convenient and quick, and the setting of the cross bar 52 can automatically determine whether the volume of the spray ball is worn to a size that cannot be used, without manual monitoring.

[0031] Specifically, the top inclined surface of each triangular counterweight block 59 is in abutment with the corresponding wedge plate 58 .

[0032] Specifically, the detection mechanism 6 includes two U-shaped grooves 61, a U-shaped rack 62, a spring column 63, a detection spring 64, a detection motor 65, a detection gear 66, a mounting plate 67, two limit blocks 68 and a slider 69. The U-shaped rack 62 is fixedly arranged on the inner wall of the spray tower 1, the two U-shaped grooves 61 are arranged on the two side walls of the U-shaped rack 62, the slider 69 is slidably arranged on the inner wall of the spray tower 1, the two limit blocks 68 are respectively fixedly arranged on the two adjacent side walls of the two second arc plates 53, one end of the spring column 63 is fixedly arranged on the side wall of the slider 69, the detection spring 64 is sleeved on the outer wall of the spring column 63, the mounting plate 67 is fixedly arranged on the end of the spring column 63, the detection motor 65 is fixedly arranged on the side wall of the second arc plate 53, and the detection gear 66 is fixedly arranged on the end of the output shaft of the detection motor 65. When the damaged spray ball in the hollow rod 57 reaches a certain weight, the resisting spring 9 is compressed to a certain distance. At this time, the limit block 68 slides to the bottom of the U-shaped slide groove 61 and moves toward the other end of the U-shaped slide groove 61 under the pulling force of the detection spring 64. At this time, the detection gear 66 is kneaded with the U-shaped rack 62, and the output shaft of the detection motor 65 rotates to drive the detection gear 66 to rotate. The rotation of the detection gear 66 drives the second arc plate 53 and the hollow rod 57 to move up synchronously; after a certain number of worn packing balls are reached, the gravity of the packing balls is used to judge that the amount of damaged packing balls inside the spray tower 1 is large, and the damaged packing balls inside need to be taken out to avoid affecting the contact purification of the exhaust gas and the spray liquid, thereby ensuring the purification effect of the spray tower 1, and no manual monitoring and regular cleaning of the inside of the spray tower 1 is required, which greatly reduces the labor intensity of the staff, and the reduction in the number of cleaning and maintenance indirectly improves the working efficiency of the spray tower 1.

[0033] Specifically, a reset transverse groove 14 is provided in the middle of the two U-shaped slide grooves 61 .

[0034] Specifically, the rotating mixing mechanism 4 includes a wedge-shaped clamp 41, a mounting rod 42, a limiting shaft 43, a rotating column 44, a limiting rotating groove 45 and a cylinder 46. The cylinder 46 is fixedly arranged on the top of the support plate 3, the rotating column 44 is rotatably arranged on the end of the output shaft of the cylinder 46, the limiting rotating groove 45 is arranged on the side wall of the rotating column 44, the mounting rod 42 is fixedly arranged on the outer side wall of the spray tower 1, the limiting shaft 43 is fixedly arranged on the top of the mounting rod 42, and the wedge-shaped clamp 41 is fixedly arranged at one end of the rotating column 44. The output shaft of the cylinder 46 extends out to drive the rotating column 44 and the wedge-shaped clamp 41 to move synchronously, and the wedge-shaped clamp 41 clamps the second arc plate 53. When the rotating column 44 moves, it is limited by the limit shaft 43 and the limit rotation groove 45. The rotating column 44 rotates while moving, and synchronously drives the wedge-shaped clamp 41 and the second arc plate 53 and the hollow rod 57 to rotate, and pours the intact spray balls above the hollow rod 57 into the spray tower 1; when the damaged filler balls are taken out, the internal layered filler balls can be mixed to ensure the contact area between the spray liquid and the exhaust gas.

[0035] Specifically, the limiting rotation groove 45 and the limiting shaft 43 are relatively slidingly limited.

[0036] Working principle: First, the exhaust gas is output to the bottom of the spray tower 1 along the ventilation pipe through the fan 7, and then the spray liquid is sprayed out from the spray head 12 through the spray pipe 11. The spray liquid circulates between a number of seasoning balls, and then the acidic components in the exhaust gas are purified by the contact between the exhaust gas and the spray liquid. As the working time increases, the packing balls at the bottom are worn out, and the severely worn packing balls fall from the gaps between the cross bars 52 to the inside of the hollow rod 57. When the damaged spray balls in the hollow rod 57 reach a certain weight, the resistance spring 9 is compressed to a certain distance. At this time, the limit block 68 slides to the bottom of the U-shaped slide groove 61 and moves toward the other end of the U-shaped slide groove 61 under the pulling force of the detection spring 64. At this time, the detection gear 66 is kneaded with the U-shaped rack 62, and the output shaft of the detection motor 65 rotates to drive the detection gear 66 to rotate. The rotation of the detection gear 66 drives the second arc plate 53 and the hollow rod 57 to move up synchronously. The second arc plate 53 moves up to make the wedge plate 58 contact the cross bar 52, so that every two adjacent wedge plates 58 move inwards, and the wedge plates 58 move inwards from The top of the hollow plate is closed to prevent the damaged filler balls inside the hollow rod 57 from falling back into the spray tower 1. When the wedge plate 58 needs to be reset, the second arc plate 53 and the hollow rod 57 are inverted, so that the triangular counterweight block 59 slowly moves down along the fixed column 55, so that the inclined surface of the triangular counterweight block 59 abuts against the wedge plate 58, so that the wedge plate 58 is separated again, which is convenient for the subsequent reinstallation of the damaged filler balls. Then, the first arc baffle 2 is opened, and the output shaft of the cylinder 46 is extended to drive the rotating column 44 and the wedge-shaped clamping claw 41 to move simultaneously. The wedge-shaped clamp 41 clamps the second curved plate 53, and the rotating column 44 is limited by the limiting shaft 43 and the limiting rotation groove 45 while moving, so that the rotating column 44 rotates while moving, and synchronously drives the wedge-shaped clamp 41, the second curved plate 53 and the hollow rod 57 to rotate, and the intact spray ball above the hollow rod 57 is poured into the spray tower 1, the second curved plate 53 is flipped over and reset, and the second curved baffle 13 is opened, and then the second curved plate 53 is inserted into the spray tower 1 and reset.
