Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a high-efficiency treatment device for acidic organic waste gas. Background Art

[0002] Some acidic gases are harmful to human health. When the atmosphere is polluted, it often contains acidic gas components such as sulfur dioxide and sulfur trioxide. Under rainy weather conditions, these acidic gases react chemically with substances such as oxygen to produce sulfuric acid, a highly acidic chemical. Sulfuric acid is highly corrosive and will corrode various objects on the surface, thus forming acid rain. Acid rain is particularly harmful to trees and vegetation, and can even cause the death of trees, which has a serious negative impact on the human living environment. When conducting experiments in chemical plants or chemical laboratories, acidic organic gases are often produced. In view of this, acidic organic gases usually need to be treated in exhaust gas treatment towers before they can be discharged into the atmosphere.

[0003] The current waste gas treatment tower treats acidic gases by introducing the acidic gases into the tower body and then spraying alkaline liquid to achieve acid-base neutralization. However, during the process of acidic gases being transported into the tower, the acidic gases will aggregate, resulting in an uneven distribution of acidic gases in the tower. As a result, during the spraying operation, it is difficult to achieve complete neutralization in areas with high acidic gas concentrations, while in areas with low acidic gas concentrations, excessive use and waste of alkaline liquid will result, ultimately leading to poor neutralization treatment of acidic gases.

[0004] Chinese patent publication number CN116272308B discloses an acidic organic waste gas treatment tower, including a tower body, the inner wall of the tower body is fixedly connected with an air inlet pipe, a gas collecting cylinder is arranged inside the tower body, the gas collecting cylinder is located at the axis of the tower body, one end of the air inlet pipe is connected with the inner wall of the gas collecting cylinder, the top and bottom of the gas collecting cylinder are provided with exhaust hoods, the outer walls of the two exhaust hoods close to each other are fixedly connected with annular sliders, the outer walls of the two annular sliders are respectively slidably connected with the inner walls of the top and bottom of the gas collecting cylinder, and the outer walls of the two exhaust hoods are evenly provided with exhaust holes.

[0005] In this treatment tower, the acidic organic waste gas is transported to the inside of the gas collecting cylinder through the air inlet pipe. The reciprocating motor drives the threaded rod to rotate back and forth, and the two exhaust hoods connected to the threaded rod will rotate back and forth with the threaded rod. The acidic gas entering the gas collecting cylinder will be dispersed through the exhaust holes of the exhaust hood. The acidic organic waste gas is highly corrosive. After it comes into contact with the threaded rod, it will corrode the surface of the threaded rod. At the same time, the rotating exhaust hood will change the surrounding airflow field distribution during operation, interfering with the normal exhaust path and rate of the exhaust gas. This causes the smoke to gather inside the exhaust hood, making it difficult to smoothly discharge outward through the exhaust holes on the exhaust hood, thereby affecting the normal operation of the entire exhaust gas emission system.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the present application provides a highly efficient treatment device for acidic organic waste gas, including a treatment tower 1 and a spray mechanism; an air inlet 111 is provided at the lower part of the treatment tower 1, and the air inlet 111 extends along the tangent direction of the outer wall of the treatment tower 1, and an air outlet 112 is provided at the upper part of the treatment tower 1, and a spray chamber 114 coaxial therewith is provided in the treatment tower 1, and the top of the spray chamber 114 is connected to the air outlet 112, and a cylindrical steady flow chamber 115 extending from bottom to top and a diverter chamber 116 distributed along the circumference of the treatment tower 1 are provided between the outer wall of the spray chamber 114 and the inner wall of the treatment tower 1, and the diverter chamber 116 is automatically arranged in the treatment tower 1 The top of the cylindrical steady flow chamber 115 is connected to the top of the diverter chamber 116, and the bottom of the diverter chamber 116 is connected to the spray chamber 114. The waste gas enters the cylindrical steady flow chamber 115 along the tangent direction of the treatment tower 1 through the air inlet 111 and passes through the diverter chamber 116 and the spray chamber 114 in turn. A liquid accumulation chamber 122 is also provided at the bottom of the inner cavity of the treatment tower 1, and the waste water generated by spraying flows into the liquid accumulation chamber 122 from top to bottom; a spray mechanism is provided in the spray chamber 114, and the spray mechanism has a nozzle 21 arranged from top to bottom in the spray chamber 114 and a water supply assembly 22 for supplying water to the nozzle 21.

[0032] A liquid discharge port 113 is also provided at the bottom of the treatment tower 1 .

[0033] An air inlet 111 is provided at the lower part of the treatment tower 1, and the air inlet 111 extends in a tangential direction along the outer wall of the treatment tower 1. This design is intended to enable the incoming exhaust gas to form a specific airflow movement pattern. An air outlet 112 is provided at the upper part of the treatment tower 1 to discharge the treated gas. Inside the treatment tower 1, a spray chamber 114 coaxial with the treatment tower 1 is arranged, and its top is connected to the air outlet 112 to ensure that the treated gas can be smoothly discharged from the treatment tower 1. Between the outer wall of the spray chamber 114 and the inner wall of the treatment tower 1, a cylindrical steady flow chamber 115 extending from bottom to top and a diversion chamber 116 distributed circumferentially along the treatment tower 1 are provided. Among them, the diversion chamber 116 is in a shape extending from top to bottom in the treatment tower 1, and the top of the cylindrical steady flow chamber 115 is connected to the top of the diversion chamber 116, and the bottom of the diversion chamber 116 is connected to the spray chamber 114. In this way, the waste gas can enter the cylindrical steady flow chamber 115 along the tangential direction of the treatment tower 1 through the air inlet 111, and form a rotating upward airflow movement under the constraint and guidance of the inner wall of the cylindrical steady flow chamber 115, and then flow through the diversion chamber 116 and the spray chamber 114 in turn. The diversion effect of the diversion chamber 116 further finely adjusts the flow path and velocity distribution of the waste gas, thereby avoiding the unfavorable situation of excessive local flow velocity, sudden change of flow direction, etc. that may be caused by the waste gas directly entering the spray chamber 114, resulting in flow field disorder, so that the waste gas undergoes an orderly treatment process in the treatment tower 1. In addition, a liquid accumulation chamber 122 is also provided at the bottom of the inner cavity of the treatment tower 1, and its function is to collect the wastewater generated during the spraying process. The wastewater flows into the liquid accumulation chamber 122 from top to bottom under the action of gravity.

[0034] The spray mechanism is arranged inside the spray chamber 114, and mainly includes nozzles 21 arranged from top to bottom in the spray chamber 114 and a water supply assembly 22 for supplying water to the nozzles 21. The nozzle 21, as an executive component of the spray, can spray alkaline liquid to the exhaust gas in the spray chamber 114 under the action of the water source provided by the water supply assembly 22, so as to achieve the treatment operation of the exhaust gas.

[0035] A drain port 113 is also provided at the bottom of the treatment tower 1, which is used to discharge the wastewater collected in the liquid accumulation chamber 122 out of the treatment tower 1 for subsequent wastewater treatment or disposal operations, thereby ensuring the normal and continuous operation of the entire exhaust gas treatment device and meeting relevant environmental protection requirements for wastewater discharge.

[0036] like Figure 2 , Figure 5 and Figure 7As shown, an inner cylinder 121 extending from top to bottom is provided at the top of the inner cavity of the treatment tower 1, and the inner cavity of the inner cylinder 121 forms a spray chamber 114. The bottom end of the inner cylinder 121 is higher than the top of the treatment tower 1 to form a liquid accumulation chamber 122 between the bottom end of the inner cavity of the treatment tower 1.

[0037] The inner cavity of the inner cylinder 121 is defined as a spray chamber 114 specifically used for waste gas spray treatment. The bottom end of the inner cylinder 121 is located higher than the top of the treatment tower 1. This relative height difference allows a liquid accumulation chamber 122 to be naturally formed between the inner cylinder 121 and the bottom end of the inner cavity of the treatment tower 1. The liquid accumulation chamber 122 can effectively collect various liquid wastes generated during the spraying process, including but not limited to products after chemical reactions with acidic organic waste gas and excess spray liquid, thereby avoiding a series of adverse effects such as corrosion of equipment and interference with normal operation of airflow caused by the random flow of these liquids in the treatment tower 1.

[0038] like Figure 2 and Figure 7 As shown, the bottom end of the inner cylinder 121 is provided with a conical cylinder 1211 coaxial therewith, and the diameter of the conical cylinder 1211 gradually decreases from top to bottom. The conical cylinder 1211 is also provided with an air pipe 1212 distributed along its circumference, and the bottom end of the air pipe 1212 is connected to the diversion chamber 116, and the top end of the air pipe 1212 is connected to the spray chamber 114. The wastewater generated in the spray chamber 114 flows into the liquid accumulation chamber 122 through the bottom opening of the conical cylinder 1211.

[0039] The bottom end of the inner cylinder 121 is provided with a conical cylinder 1211 structure coaxial therewith. The diameter of the conical cylinder 1211 shows a trend of gradually decreasing from top to bottom. In the internal structure of the conical cylinder 1211, there are air pipe 1212 components distributed along its circumference. The bottom ends of these air pipes 1212 establish a stable connection relationship with the diversion chamber 116, and the top ends are connected to the spray chamber 114. During the operation of the waste gas treatment, the wastewater generated by the spraying operation inside the spray chamber 114 will flow into the liquid accumulation chamber 122 located below it in an orderly manner through the opening structure at the bottom of the conical cylinder 1211 under the combined effect of multiple factors such as gravity and the pressure difference inside the system. Through the synergistic effect of the conical cylinder 1211 and the air pipe 1212, on the one hand, the fluid transmission between the spray chamber 114 and the diversion chamber 116 can be accurately regulated and guided, ensuring that the flow path of the exhaust gas between different treatment chambers is more reasonable and efficient; on the other hand, the setting of the bottom opening of the conical cylinder 1211 provides a convenient channel for the smooth discharge of wastewater, so that the wastewater can be quickly and effectively collected into the liquid accumulation chamber 122, avoiding the retention of wastewater in the spray chamber 114 and the surrounding areas, thereby effectively preventing a series of adverse consequences such as corrosion of equipment and affecting the spraying effect caused by the retention of wastewater, further improving the stability, reliability and treatment efficiency of the entire acidic organic waste gas treatment device, and providing solid technical support and structural guarantee for achieving efficient treatment of acidic organic waste gas and environmental protection goals.

[0040] like Figure 5 As shown, an outer cylinder 131 coaxial with the inner cylinder 121 is also arranged between the outer wall of the inner cylinder 121 and the inner wall of the treatment tower 1, and a sealing ring 1311 sealedly connected to the inner wall of the treatment tower 1 is arranged at the bottom end of the outer cylinder 131, and the sealing ring 1311 is lower than the air inlet 111, and a buffer chamber 132 is formed between the top of the outer cylinder 131 and the top of the inner cavity of the treatment tower 1, and the cylindrical steady flow chamber 115 is formed between the outer wall of the outer cylinder 131 and the inner wall of the treatment tower 1, and a diverter plate 133 distributed along the circumference of the inner cylinder 121 is arranged between the inner wall of the outer cylinder 131 and the outer wall of the inner cylinder 121, and the diverter plate 133 extends in the vertical direction, and the diverter chamber 116 is formed between adjacent diverter plates 133.

[0041] In the internal structural system of the treatment tower 1, an outer cylinder 131 structure coaxial with the inner cylinder 121 is additionally provided between the outer wall of the inner cylinder 121 and the inner wall of the treatment tower 1. The bottom end of the outer cylinder 131 is equipped with a sealing ring 1311 in a sealed connection with the inner wall of the treatment tower 1. The position of this sealing ring 1311 is at a height level lower than the air inlet 111. Its main function is to effectively isolate and seal specific areas to prevent gas or liquid from leaking or flowing abnormally on unexpected paths, thereby ensuring the independence and stability of each functional area inside the treatment tower 1. A buffer chamber 132 is constructed between the top of the outer cylinder 131 and the top of the inner cavity of the treatment tower 1. The buffer chamber 132 can play a role in buffering and regulating the flow state of the gas during the waste gas treatment process, so that the gas can be more evenly and stably distributed before entering the subsequent treatment link, reducing the adverse effects of sudden changes in air flow or pressure fluctuations on the treatment effect. The space formed between the outer wall of the outer cylinder 131 and the inner wall of the treatment tower 1 is the cylindrical steady flow chamber 115, which serves as the preliminary treatment area after the waste gas enters the treatment tower 1. It can perform preliminary steady flow operations on the waste gas entering from the tangential direction of the air inlet 111, so that the waste gas gradually forms an orderly rotating upward airflow in this area, laying a good flow field foundation for subsequent diversion treatment. At the same time, between the inner wall of the outer cylinder 131 and the outer wall of the inner cylinder 121, there are diverter plates 133 distributed along the circumference of the inner cylinder 121. These diverter plates 133 extend in the vertical direction, and the diverter chamber 116 is defined between two adjacent diverter plates 133. The diversion chamber 116 undertakes the key task of further diverting the waste gas after steady flow treatment in the entire waste gas treatment process. Through the layout and guiding function of the diversion plate 133, the waste gas can enter the spray chamber 114 in a more uniform and dispersed manner, thereby improving the efficiency and uniformity of the spray treatment, and ensuring that the acidic organic waste gas can be fully and effectively treated in each treatment link.

[0042] like Figure 3 As shown, a pressure ring 14 is provided at the top of the buffer chamber 132, an elastic pressure assembly is provided between the top of the pressure ring 14 and the top of the processing tower 1, the outer wall of the pressure ring 14 and the inner wall of the processing tower 1 are sealed and slidably matched, the inner wall of the pressure ring 14 and the outer wall of the inner cylinder 121 are sealed and slidably matched, and an arc-shaped groove 141 is provided at the bottom end of the pressure ring 14.

[0043] The top of the buffer chamber 132 is provided with a pressure ring 14 component. An elastic pressure assembly is assembled between the top of the pressure ring 14 and the top of the treatment tower 1. The elastic pressure assembly can produce corresponding elastic deformation according to the pressure changes inside the system, and then exert an adjustable force on the pressure ring 14 to maintain the dynamic balance and stability of the pressure inside the system. The outer wall of the pressure ring 14 and the inner wall of the treatment tower 1 are connected in a sealed sliding manner. This connection method ensures that when the pressure ring 14 is axially displaced relative to the inner wall of the treatment tower 1, it can effectively prevent gas or liquid from leaking from the matching gap between the two, thereby ensuring the sealing and stability of the pressure ring 14 environment inside the treatment tower 1. At the same time, the inner wall of the pressure ring 14 and the outer wall of the inner cylinder 121 also adopt a sealed sliding fitting structure, which further enhances the sealing and coordination of the pressure ring 14 in the entire internal structure of the treatment tower 1. At the bottom end of the pressure ring 14, an arc groove 141 structure is provided. When the airflow or pressure in the buffer chamber 132 changes, the arc-shaped groove 141 can guide the flow direction of the airflow so that it forms a specific flow field distribution pattern at the bottom of the pressure ring 14, thereby reducing the direct force of the airflow impact on the pressure ring 14 and related components, extending the service life of the components, and helping to improve the stability and reliability of the entire buffer chamber 132 and even the entire treatment tower 1 when dealing with pressure fluctuations.

[0044] like Figure 3 As shown, the elastic pressure assembly includes a fixing ring 151, a connecting column 152, a positioning ring 153 and an elastic pressure element 154; the fixing ring 151 is coaxially fixedly arranged on the top of the processing tower 1; a conical surface is arranged on the top of the processing tower 1, and the connecting column 152 is distributed along the circumference of the processing tower 1, and the connecting column 152 slides along the vertical direction to match the conical surface, and the top of the connecting column 152 passes through the fixing ring 151 and a limiting ring 155 is arranged; the positioning ring 153 is coaxially screwed on the connecting column 152, and the positioning ring 153 is located between the fixing ring 151 and the conical surface; the elastic pressure element 154 is sleeved on the connecting column 152, and the elastic pressure element 154 is located between the positioning ring 153 and the fixing ring 151.

[0045] The fixing ring 151 is precisely set at the top of the processing tower 1 in a coaxial fixed manner, providing a stable installation foundation and positioning reference for the entire elastic pressure assembly. The top of the processing tower 1 is constructed with a specific conical surface, and the connecting column 152 is distributed and arranged along the circumference of the processing tower 1, and the connecting column 152 and the conical surface form a sliding fit relationship in the vertical direction. This sliding fit mechanism enables the connecting column 152 to move smoothly in the vertical direction along the conical surface when it is subjected to external force or the internal pressure of the system changes. The top of the connecting column 152 passes through the fixing ring 151 and is provided with a limiting ring 155. The existence of the limiting ring 155 effectively prevents the connecting column 152 from escaping from the fixing ring 151 during movement, ensuring that the connecting column 152 operates stably within a predetermined range of motion, thereby maintaining the integrity and reliability of the entire elastic pressure assembly structure.

[0046] The positioning ring 153 is installed on the connecting column 152 in a coaxial screwing manner, and its position is located between the fixing ring 151 and the conical surface. The positioning ring 153 plays an important positioning and adjustment function in the elastic pressure assembly. Through the screwing operation, its position height on the connecting column 152 can be accurately adjusted, and then the pre-compression amount or pre-stretching amount of the elastic pressure element 154 can be finely set to meet the pressure adjustment requirements under different working conditions.

[0047] The elastic pressure element 154 is sleeved on the connecting column 152 and is located between the positioning ring 153 and the fixing ring 151. The elastic pressure element 154 can produce corresponding elastic deformation when the system pressure changes based on its own elastic characteristics. When the pressure inside the treatment tower 1 increases, the elastic pressure element 154 will be deformed by the compression force and store elastic potential energy; when the pressure decreases, the elastic pressure element 154 releases the elastic potential energy and returns to its original state. In this way, the dynamic pressure regulation effect of the pressure ring 14 is achieved, so that the internal pressure of the treatment tower 1 is always maintained within a relatively stable range.

[0048] like Figure 8 As shown, the water supply assembly 22 includes a water supply pipe coaxially arranged in the spray chamber 114 and a water pump connected to the water supply pipe, the nozzles 21 are distributed on the water supply pipe, a water outlet 16 is provided at the lower part of the treatment tower 1, and the water inlet pipe of the water pump is connected to the water outlet 16.

[0049] The water supply pipe is coaxially located in the spray chamber 114, and is designed to ensure uniform water supply to the spray chamber 114, providing a stable water source for the effective spraying operation of the subsequent nozzles 21. The nozzles 21 are arranged on the water supply pipe in a specific distribution form, and this distribution mode is carefully designed to enable the spray liquid to form a comprehensive, uniform spray effect with a specific coverage range and spray intensity in the spray chamber 114, thereby achieving full contact and treatment of the acidic organic waste gas.

[0050] A water outlet 16 structure is provided at the lower part of the treatment tower 1, and the water outlet 16 establishes a communication relationship with the water inlet pipe of the water pump. In this way, during the operation of the entire spray system, the liquid in the liquid accumulation chamber 122 at the bottom of the treatment tower 1 can be drawn into the water inlet pipe of the water pump through the water outlet 16. The water pump, as a power drive device, pressurizes the drawn liquid and transports it to the water supply pipe, thereby providing the nozzles 21 distributed on the water supply pipe with a certain pressure and flow rate for spraying liquid. This circulating water supply mechanism not only effectively utilizes the wastewater generated by spraying and reduces the waste of water resources, but also ensures the continuity and stability of the spraying operation. It can accurately adjust the water supply pressure and flow rate according to the actual needs of waste gas treatment in the treatment tower 1 to meet the requirements of acidic organic waste gas treatment under different working conditions.

[0051] like Figure 2 , Fig. 9 and Fig.10 As shown, the inner wall of the inner cylinder 121 is provided with an outer deflection cone 171 distributed in the vertical direction, an inner deflection port 172 is formed between the inner edge of the outer deflection cone 171 and the outer wall of the water supply pipe, the outer wall of the water supply pipe is provided with an inner deflection cone 173 distributed in the vertical direction, an outer deflection port 174 is formed between the outer edge of the inner deflection cone 173 and the inner wall of the treatment tower 1, a deflection channel 175 is formed between the outer deflection cone 171 and the inner deflection cone 173, the nozzle 21 is located between adjacent inner deflection cones 173, and the nozzle of the nozzle 21 faces the inner deflection port 172.

[0052] The inner edge of the outer baffle cone 171 and the outer wall of the water supply pipe define a special fluid channel area, the inner baffle port 172. At the same time, the outer wall of the water supply pipe is also equipped with an inner baffle cone 173 distributed in the vertical direction, and the outer edge of the inner baffle cone 173 and the inner wall of the treatment tower 1 together form an outer baffle port 174. A baffle channel 175 is formed between the outer baffle cone 171 and the inner baffle cone 173. The nozzle 21 is positioned between adjacent inner baffle cones 173, and the nozzle of the nozzle 21 faces the inner baffle port 172.

[0053] In the actual operation of waste gas treatment, when the spray liquid is ejected from the nozzle 21, since the nozzle of the nozzle 21 is facing the inner deflection port 172, the ejected liquid will first enter the inner deflection port 172 area. In this area, the liquid will flow along the specific spatial path of the inner deflection port 172 under the action of pressure and inertia, and will have the first contact and interaction with the waste gas passing through the inner deflection port 172, and preliminarily achieve partial treatment of the waste gas and impurity removal. Subsequently, the mixture of liquid and waste gas flows through the deflection channel 175. The special shape and structural design of the deflection channel 175 make the mixture undergo multiple changes in direction and speed adjustments when flowing through. This deflection effect greatly prolongs the contact time and contact area between the liquid and the waste gas, promotes full reaction and material exchange between the two, and further improves the treatment effect. Finally, the fully treated mixture flows through the outer deflection port 174, and completes the final treatment and purification process in this area to ensure that the gas discharged from the treatment tower 1 meets the relevant environmental protection standards and requirements.

[0054] like Figure 2 As shown, 9. A high-efficiency treatment device for acidic organic waste gas according to claim 8 is characterized in that the bottom end of the outer deflection cone 171 is provided with a drainage cone 176 whose inner edge is coaxially fixedly connected thereto, the drainage cone 176 extends downwardly at an angle, and a drainage port 177 is formed between the outer edge of the drainage cone 176 and the inner wall of the inner cylinder 121, and the bottom end of the outer deflection cone 171 is provided with a water outlet 178 located at the top of the drainage cone 176.

[0055] In the operation process of the entire acidic organic waste gas treatment device, after the spray liquid undergoes the flow and treatment process in the treatment tower 1, part of the liquid converges at the bottom area of ​​the outer deflection cone 171 under the combined influence of factors such as gravity and the internal pressure difference of the system, in order to avoid the liquid forming a water curtain at the inner deflection port 172 and causing the waste liquid to reset. The liquid first enters the top area of ​​the drainage cone 176 through the water flow port 178. Due to the special structural design of the drainage cone 176 that extends downward in an inclined manner, the liquid will flow downward along its top after entering, and under the guidance and constraint of the drainage port 177, it will circulate at the top of the outer deflection cone 171, forming a liquid flow with a specific flow direction and flow rate until it flows into the liquid accumulation chamber 122.

[0056] like Figure 2 As shown, the inner edge of the outer deflector cone 171 is provided with an anti-overflow cylinder 179 coaxial therewith, and the top end of the anti-overflow cylinder 179 is higher than the inner edge of the outer deflector cone 171.

[0057] In order to prevent the liquid from passing through the inner deflection port 172 , an anti-overflow cylinder 179 is provided to gather the liquid at the top of the water flow port 178 , thereby preventing the liquid from flowing through the water flow port 178 to the top of the drainage cone 176 .

[0058] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
