Description

Technical Field

[0001] This invention relates to the field of exhaust gas deodorization structure technology, and in particular to an exhaust gas deodorization device for a solid waste workshop. Background Technology

[0002] In the production processes of existing factories, steel mills, pharmaceutical plants, coking plants, and oil refineries, various waste gases are often generated in the workshops. Currently, workshop waste gases have become one of the main sources of air pollution. According to environmental protection requirements, the waste gases emitted from the production workshops of enterprises must be purified before they can be discharged.

[0003] Currently, different treatment methods are adopted for treating workshop exhaust gas according to the type and properties of the exhaust gas. Generally, different cleaning liquids are selected according to the chemical properties of the exhaust gas, and spraying is used to remove odors from the exhaust gas and reduce harmful substances inside the exhaust gas.

[0004] In existing spray deodorization equipment, the absorbent liquid and contact purification packing layer are both in a fixed state during the spray deodorization process. During this process, the gas flow rate is relatively high, and the contact time between the gas and the packing layer and cleaning liquid is limited, easily leading to incomplete deodorization. Simultaneously, solid impurities in the waste gas are easily trapped and adhere to the surface of the packing layer under the impact of the cleaning liquid. Since the packing layer is in a fixed state, solid impurities tend to accumulate, hindering contact between the waste gas and the packing layer surface and reducing the deodorization effect. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a solid waste workshop exhaust gas deodorization device.

[0006] To achieve the above objectives, this application provides the following technical solution: a solid waste workshop exhaust gas deodorization device, including a collection rack, a notch provided above the collection rack, a positioning rack installed directly above the notch, and a cleaning liquid spraying unit installed on the surface of the positioning rack.

[0007] It also includes a deodorizing unit disposed in the inner cavity of the collection rack. The deodorizing unit is located directly below the cleaning liquid spraying unit, and the deodorizing unit can swing within the inner cavity of the collection rack to contact the exhaust gas entering the inner cavity of the collection rack and positioning rack.

[0008] An impurity removal unit is provided on the outside and below the deodorizing unit. The impurity removal unit can swing inside the collection rack, and the swing direction of the impurity removal unit is opposite to that of the deodorizing unit. It is used to receive the impurities swirled out by the deodorizing unit.

[0009] Furthermore, the cleaning liquid spraying unit includes a liquid guiding pipe installed on the upper surface of the positioning frame. A nozzle is installed at the outlet end of the liquid guiding pipe, and a delivery pipe is installed at the inlet end of the liquid guiding pipe. The nozzle extends to the inner side of the positioning frame, and an electrically controlled valve is installed on the surface of the nozzle.

[0010] Furthermore, the deodorizing unit includes multiple sets of deodorizing fillers distributed in a ring structure. Each set of deodorizing fillers has a limiting plate that fits against its front and rear ends. The limiting plates on the same side are fixed together by a linkage ring. The inner surface of the linkage ring is fixedly connected with an alignment frame.

[0011] Furthermore, a drive shaft is provided through the surface of the alignment frame, and the end of the drive shaft passes through the collection frame and is equipped with a linkage wheel. An active wheel is installed on one side of the linkage wheel, and the linkage wheel and the active wheel are connected by a synchronous belt. A servo motor adapted to the active wheel is installed at the shaft center of the active wheel.

[0012] Furthermore, the impurity removal unit includes an impurity removal filter screen disposed directly below the deodorizing filler. The impurity removal filter screen has a side-lying semi-cylindrical structure. Impurities located on the surface of the deodorizing filler can be rotated out to the surface of the impurity removal filter screen. An alignment frame is fixedly connected to the upper surface of the impurity removal filter screen. The left and right ends of the lower surface of the alignment frame are connected to the arc-shaped edge of the impurity removal filter screen through extension frames.

[0013] Furthermore, a second drive shaft is installed on the surface of the alignment frame located on one side of the impurity removal filter. The second drive shaft passes through the collection frame and is equipped with a second linkage wheel. A second active wheel is provided on one side of the second linkage wheel, and the second linkage wheel and the second active wheel are connected by a second synchronous belt. A second servo motor adapted to the second active wheel is installed at the axis of the second active wheel.

[0014] Furthermore, the outer surface of the collection rack is equipped with an inlet pipe and an outlet pipe for the flow of exhaust gas by screws on both sides. The exhaust gas flows through the inlet pipe into the interior of the positioning rack and the collection rack under the action of the fan, and is then discharged through the outlet pipe.

[0015] Furthermore, a drainage pipe is embedded in the center of the lower surface of the collection rack, through which sewage falling from the surface of the impurity removal filter is discharged to the outside of the collection rack.

[0016] Furthermore, the lower surface of the collection rack is fitted with support frames at both the left and right ends by screws, and the bottom end of the support frame rests on the ground.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] 1. This invention utilizes a swingable deodorizing filler that swirls and guides the airflow, causing it to tumble and contact the oscillating filler. This increases the contact area between the filler and the airflow, ensuring sufficient contact between the airflow and the filler, as well as the cleaning liquid adhering to its surface, thus improving the efficiency of the deodorizing process.

[0019] 2. The deodorizing filler in this invention can quickly remove impurities adhering to its surface during the oscillation process. The impurities fall under the action of gravity, reducing the adhesion of impurities to the deodorizing filler and effectively avoiding the phenomenon of reduced deodorization effect caused by impurities adhering to the surface of the deodorizing filler for a long time and blocking the contact of exhaust gas. It has a self-cleaning effect.

[0020] 3. This invention provides a waste removal filter screen located below the deodorizing packing material. The impurities on the surface of the waste removal filter screen can continuously change position. Wastewater falling through the deodorizing packing material can come into contact with different positions on the surface of the waste removal filter screen, effectively avoiding wastewater blockage caused by the accumulation of impurities. It is suitable for long-term and continuous waste gas deodorization. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example: Reference Figure 1 , Figure 2 The solid waste workshop exhaust gas deodorization equipment shown includes a collection rack 1, with a notch at the top of the collection rack 1, and a positioning rack 2 installed directly above the notch. A cleaning liquid spraying unit is installed on the surface of the positioning rack 2.

[0032] It also includes a deodorizing unit installed in the inner cavity of the collection rack 1. The deodorizing unit is located directly below the cleaning liquid spraying unit, and the deodorizing unit can swing in the inner cavity of the collection rack 1 to contact the exhaust gas entering the inner cavity of the collection rack 1 and the positioning rack 2.

[0033] An impurity removal unit is provided on the outside and below the deodorizing unit. The impurity removal unit can swing inside the collection rack 1, and the swing direction of the impurity removal unit is opposite to that of the deodorizing unit. It is used to receive the impurities swirled out by the deodorizing unit.

[0034] like Figure 2 , Figure 3 As shown, the cleaning fluid spraying unit includes a fluid guiding pipe 23 mounted on the upper surface of the positioning frame 2. Each outlet end of the fluid guiding pipe 23 is equipped with a nozzle 25, and each inlet end of the fluid guiding pipe 23 is equipped with a delivery pipe 26. The nozzles 25 extend to the inner side of the positioning frame 2, and each nozzle 25 is equipped with an electrically controlled valve 24. The deodorizing cleaning fluid can enter the fluid guiding pipe 23 through the delivery pipe 26 and, with the electrically controlled valve 24 open, can be smoothly discharged through the nozzles 25.

[0035] like Figure 4 , Figure 5As shown, the deodorization unit includes multiple sets of deodorizing fillers 3 arranged in a ring structure. Each set of deodorizing fillers 3 has a limiting plate 31 at both its front and rear ends, which fits against it. The limiting plates 31 on the same side are fixed together by a linkage ring 32, and the inner surface of the linkage ring 32 is fixedly connected to an alignment frame 33. The cleaning liquid sprayed through the nozzle 25 comes into contact with the waste gas and the deodorizing fillers 3. During the process of the waste gas flowing inside the collection frame 1 and the positioning frame 2, it comes into contact with the cleaning liquid and the deodorizing fillers 3, which has the effect of deodorizing and purifying the waste gas, reducing the odor and harmful substances inside the waste gas.

[0036] like Figure 6 As shown, a drive shaft 34 is provided through the surface of the alignment frame 33. The end of the drive shaft 34 passes through the collection frame 1 and is equipped with a linkage wheel 35. An active wheel 36 is installed on one side of the linkage wheel 35. The linkage wheel 35 and the active wheel 36 are connected by a synchronous belt 37. A servo motor 38 adapted to the active wheel 36 is installed at the shaft center of the active wheel 36.

[0037] In actual operation, the servo motor 38 is controlled by the terminal PLC controller. When it is powered on, the active rotating wheel 36 can rotate on the outside of the collection rack 1. Under the connection of the synchronous belt 37, the linkage rotating wheel 35 can drive the drive shaft 34, the alignment frame 33 and the linkage ring 32 to swing synchronously, so as to drive the deodorizing filler 3 to swing.

[0038] During the oscillation process, the deodorizing packing 3 has a swirling and guiding effect on the airflow, causing the airflow to tumble and come into contact with the deodorizing packing 3 in the oscillating state. This increases the contact area between the deodorizing packing 3 and the airflow, allowing the airflow to fully contact the deodorizing packing 3 and the cleaning liquid adhering to its surface. Impurities adhering to the airflow are quickly adsorbed and separated from the exhaust gas, improving the efficiency of the deodorization work and enhancing the deodorization effect.

[0039] At the same time, as the deodorizing filler 3 swings, the impurities adhering to its surface can be quickly rotated out. The impurities fall under the action of gravity, reducing the adhesion of impurities to the deodorizing filler 3. This effectively avoids the phenomenon of reduced deodorization effect caused by impurities adhering to the surface of the deodorizing filler 3 for a long time and blocking the contact of exhaust gas. It has a self-cleaning effect.

[0040] like Figure 4 , Figure 5As shown, the impurity removal unit includes an impurity removal filter screen 4 positioned directly below the deodorizing packing 3. The filter screen 4 has a sideways, semi-cylindrical structure. Impurities on the surface of the deodorizing packing 3 are rotated out to the surface of the filter screen 4 as the deodorizing packing 3 rotates. Wastewater passes through the surface of the filter screen 4 and falls to the bottom of the inner cavity of the collection rack 1, thus achieving the purpose of separating wastewater from impurities, allowing for separate recycling of both. An alignment frame 41 is fixedly connected to the upper surface of the filter screen 4. The lower surface of the alignment frame 41 is connected to the arc-shaped edge of the filter screen 4 at both the left and right ends through an extension frame 42.

[0041] like Figure 7 As shown, a drive shaft 43 is installed on the surface of the alignment frame 41 on one side of the impurity removal filter screen 4. The drive shaft 43 passes through the collection rack 1 and is equipped with a linkage wheel 44. An active wheel 45 is provided on one side of the linkage wheel 44, and the linkage wheel 44 and the active wheel 45 are connected by a synchronous belt 46. A servo motor 47 adapted to the active wheel 45 is installed at the shaft center of the active wheel 45.

[0042] In actual operation, the servo motor 47 is controlled by the terminal PLC controller. When it is powered on, the active rotating wheel 45 can rotate on the outside of the collection rack 1. Under the connection of the synchronous belt 46, the linkage rotating wheel 44 can drive the drive shaft 43 and the impurity filter 4 to swing synchronously.

[0043] During the oscillation process, the wastewater falling through the deodorizing packing 3 can land at different positions on the surface of the impurity removal filter screen 4. The impurities on the surface of the impurity removal filter screen 4 can continuously change positions. The wastewater falling through the deodorizing packing 3 can come into contact with different positions on the surface of the impurity removal filter screen 4, effectively avoiding the wastewater blockage caused by the accumulation of impurities. This facilitates the rapid discharge of wastewater and prevents wastewater from lingering above the impurity removal filter screen 4 and re-contaminating the deodorizing packing. It also reduces the frequency of manual cleaning and dredging and is suitable for long-term, continuous exhaust gas deodorization work.

[0044] like Figure 3 As shown, the outer surface of the collection rack 1 is fitted with an inlet pipe 21 and an outlet pipe 22 on both sides by screws, allowing the waste gas to flow. Under the action of the fan, the waste gas flows through the inlet pipe 21 into the interior of the positioning rack 2 and the collection rack 1, and then is discharged through the outlet pipe 22. The discharged waste gas can enter the scrubbing tower for further purification and disinfection. Only after the waste gas meets the standards can it be discharged into the atmosphere.

[0045] like Figure 2 As shown, a drain pipe 11 is embedded in the center of the lower surface of the collection rack 1. Wastewater falling through the surface of the impurity removal filter screen 4 flows through the drain pipe 11 and is discharged to the outside of the collection rack 1. Further purification and recycling operations can be carried out on the wastewater after impurity removal.

[0046] like Figure 5 As shown, support frames 12 are installed on the left and right ends of the lower surface of the collection rack 1 by screws. The bottom end of the support frame 12 is attached to the ground. The support frame 12 can stably install the collection rack 1 and the positioning frame 2 on its top, leaving a certain distance from the ground to allow space for sewage to fall and be discharged.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
