Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, specifically a waste gas spraying assembly for waste gas treatment. Background Technology

[0002] Industrial production processes generate large amounts of waste gas containing harmful substances. Direct release of this waste gas into the atmosphere can cause serious environmental pollution and harm human health. Among existing waste gas treatment technologies, spraying is a common and effective method. By ensuring thorough contact between the sprayed liquid and the waste gas, the harmful substances in the waste gas are absorbed or reacted, thereby achieving the purpose of purifying the waste gas.

[0003] However, traditional exhaust gas spraying devices have some shortcomings, such as uneven spraying, resulting in some exhaust gas not fully contacting the spray liquid and poor purification effect; the filter structure is easily clogged by impurities, affecting exhaust gas flow and treatment efficiency, and is inconvenient to clean, increasing maintenance costs and workload. Therefore, a new type of exhaust gas spraying component is needed to improve these problems. Utility Model Content

[0004] This invention provides an exhaust gas spraying component for exhaust gas treatment, which addresses the problems of uneven spraying, easy clogging of the filter structure by impurities leading to insufficient contact between some exhaust gas and the spray liquid, and inconvenient cleaning of the filter structure, resulting in increased maintenance costs and workload.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: a waste gas spraying component for waste gas treatment, including a support leg, a spraying cylinder fixedly connected to the upper end of the support leg, an air inlet pipe installed at the bottom of the spraying cylinder, an air outlet pipe installed at the upper end of the spraying cylinder, a spraying structure provided inside the spraying cylinder, and a filter structure provided on the inner side of the spraying cylinder near the middle.

[0006] The spray structure includes a water inlet pipe, which is located above the middle of the spray cylinder. A rotating connector is installed at the lower end of the water inlet pipe, and a water guide pipe is connected to the lower end of the rotating connector. A drive unit is installed on the water guide pipe, and a spray disc is connected to the lower end of the water guide pipe. A cleaning unit is fixedly connected to the lower middle part of the spray disc.

[0007] Furthermore, a hollow cone is provided at the bottom center of the spray cylinder corresponding to the position of the air inlet pipe, and a guide ring is provided on the bottom side wall of the spray cylinder.

[0008] Furthermore, the cross-section of the guide ring is triangular, with its hypotenuse facing the hollow cone.

[0009] Furthermore, the drive unit includes a driven gear fixedly mounted on the upper end of the water guide pipe, a drive gear meshing with the side of the driven gear, the drive gear being fixedly mounted on the output shaft of the drive motor, and the bottom of the drive motor being fixedly mounted on the upper end of the spray cylinder.

[0010] Furthermore, the spray disc has a hollow structure and atomizing nozzles are evenly arranged on its lower end face.

[0011] Furthermore, the cleaning unit includes a vertical shaft fixedly connected to the middle of the lower end face of the spray plate. The lower end of the vertical shaft passes through the filter structure and is fixedly connected to a linkage plate. Brushes are symmetrically arranged on the linkage plate, and ball-head rods are fixedly installed on the linkage plate on the side of the brushes.

[0012] Furthermore, the filter structure includes a circular filter screen, an annular groove is provided on the inner side of the spray cylinder near the middle, the circular filter screen is slidably disposed in the annular groove, and a spiral spring is evenly disposed on the lower end face of the circular filter screen near the edge, with the lower end of the spiral spring fixedly installed at the bottom of the annular groove.

[0013] Furthermore, the lower end of the circular filter screen and the upper end of the brush are in contact with each other.

[0014] Furthermore, the lower end face of the circular filter screen has protrusions evenly distributed along its circumference near the edge, and the protrusions slide in conjunction with the ball head rod.

[0015] Furthermore, a drain pipe is also installed on the side of the air intake pipe for discharging spray wastewater.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] 1. The spray disc is rotated by the drive unit, so that the spray liquid is evenly sprayed from the atomizing nozzle and fully contacts the exhaust gas, which improves the exhaust gas purification effect. The cleaning unit rotates with the spray disc, and the brush cleans the circular filter screen. At the same time, the ball head rod and the protrusion cooperate to make the circular filter screen vibrate up and down, which effectively prevents the circular filter from clogging, ensures smooth exhaust gas flow, improves treatment efficiency, and reduces the workload and maintenance cost of manual cleaning.

[0019] 2. The hollow cone and guide ring design allow the exhaust gas to diffuse evenly upwards, which is beneficial for thorough mixing with the spray liquid. The filter structure is slidably set in the annular groove and is equipped with a spiral spring, which gives the circular filter screen a certain degree of elasticity and buffering, thus extending its service life.

A rotating connector 52 is installed at the lower end of the water inlet pipe 51. A water guide pipe 53 is connected to the lower end of the rotating connector 52. A drive unit 54 is installed on the water guide pipe 53. A spray disc 55 is connected to the lower end of the water guide pipe 53. A cleaning unit 56 is fixedly connected to the middle of the lower end of the spray disc 55.

[0036] A hollow cone 21 is provided at the bottom center of the spray cylinder 2, corresponding to the position of the air inlet pipe 3, and a guide ring 22 is provided on the bottom side wall of the spray cylinder 2.

[0037] The flow guide ring 22 has a triangular cross-section with its hypotenuse facing the hollow cone 21.

[0038] The drive unit 54 includes a driven gear 541 fixedly mounted on the upper end of the water guide pipe 53, a drive gear 542 meshing with the side of the driven gear 541, the drive gear 542 being fixedly mounted on the output shaft of the drive motor 543, and the bottom of the drive motor 543 being fixedly mounted on the upper end of the spray cylinder 2.

[0039] The spray plate 55 is a hollow structure and its lower end face is uniformly provided with atomizing nozzles 551.

[0040] The cleaning unit 56 includes a vertical shaft 561 fixedly connected to the middle of the lower end face of the spray plate 55. The lower end of the vertical shaft 561 passes through the filter structure 6 and is fixedly connected to a linkage plate 562. A brush 563 is symmetrically arranged on the linkage plate 562. A ball head rod 564 is fixedly installed on the linkage plate 562 on the side of the brush 563.

[0041] The filter structure 6 includes a circular filter screen 61. An annular groove 62 is provided on the inner side of the spray cylinder 2 near the middle. The circular filter screen 61 is slidably disposed in the annular groove 62, and a spiral spring 63 is evenly disposed on the lower end face of the circular filter screen 61 near the edge. The lower end of the spiral spring 63 is fixedly installed at the bottom of the annular groove 62.

[0042] The lower end of the circular filter screen 61 and the upper end of the brush 563 are in contact with each other.

[0043] The circular filter screen 61 has protrusions 64 evenly arranged around its circumference near the edge of its lower end face, and the protrusions 64 and the ball head rod 564 are in sliding engagement.

[0044] The air intake pipe 3 is also equipped with a sewage pipe 7 on its side for discharging spray wastewater.

[0045] Working principle:

[0046] First, fix the end of the water inlet pipe 51 to the existing water supply equipment. Then, let the exhaust gas enter the bottom of the spray cylinder 2 through the air inlet pipe 3. Since there is a hollow cone 21 in the middle of the bottom of the spray cylinder 2 corresponding to the position of the air inlet pipe 3, the exhaust gas will diffuse upward along the hollow cone 21.

[0047] Turn on the existing water supply equipment, and the inlet pipe 51 introduces the spray liquid. It enters the guide pipe 53 through the rotating connector 52, and then enters the spray plate 55 through the guide pipe 53. Start the drive motor 543, which drives the drive gear 542 to rotate. Under the meshing action of the drive gear 542 and the driven gear 541, the guide pipe 53 rotates synchronously. The guide pipe 53 drives the spray plate 55 to rotate. During the rotation, the spray liquid is evenly sprayed out from the atomizing nozzle 551 and fully contacts the rising exhaust gas, so that the harmful substances in the exhaust gas react.

[0048] In the early stage of exhaust gas rise, the circular filter screen 61 in the filter structure 6 can filter the exhaust gas, thereby filtering fine particulate matter in the exhaust gas onto the lower surface of the circular filter screen 61. During the rotation of the spray disc 55, the spray disc 55 will also drive the vertical shaft 561 to rotate synchronously. The vertical shaft 561 drives the linkage plate 562 and the brush 563 to rotate synchronously. The brush 563 contacts the lower end face of the circular filter screen 61 and cleans the lower surface of the circular filter screen 61 during the rotation to prevent it from clogging. During the rotation of the linkage plate 562, the ball head rod 564 will also rotate and intermittently squeeze the protrusion 64. With the cooperation of the spiral spring 63, the circular filter screen 61 can vibrate up and down in the annular groove 62 to further enhance the cleaning effect and improve the exhaust gas filtration efficiency.

[0049] The purified exhaust gas after spraying and filtration is discharged through the exhaust pipe 4. The wastewater generated during the spraying process is discharged through the drain pipe 7 installed on the side of the intake pipe 3. During the wastewater discharge process, the brushed particles can also be carried out simultaneously, reducing the difficulty of subsequent cleaning.
