To accommodate large waste gas flow rates, the devices often have a large internal gas flow space to ensure all waste gas enters this space. However, within this large internal space, the waste gas flow rate is relatively slow, resulting in insufficient contact between the waste gas and the liquid and consequently, low waste gas treatment efficiency.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] like Figure 1 As shown in the illustration, this application provides a spray tower device for high-efficiency gas-liquid reaction, comprising a spray tower body 101, a jet assembly, and a spray assembly. The spray tower body 101 serves as the main support of the spray tower device and houses the jet assembly and the spray assembly. During the passage of waste gas through the spray tower body 101, the spray assembly, in conjunction with the jet assembly, treats the waste gas, thereby improving waste gas treatment efficiency.

[0033] In some examples, the spray tower body 101 is formed as a cylindrical structure, that is, the spray tower body 101 has an internal cavity. The spray tower body 101 is placed vertically and has a certain height.

[0034] In some examples, the spray tower body 101 is provided with an air inlet 102 and an air outlet 103. The exhaust gas enters the inner cavity of the spray tower body 101 along the air inlet 102 and is finally discharged from the spray tower body 101 along the air outlet 103.

[0035] The spray tower body 101 is roughly cylindrical in shape. Since the spray tower body 101 is vertically installed, the air inlet 102 is located on the side wall of the spray tower body 101 and is located near the bottom of the spray tower body 101, while the air outlet 103 is located on the top of the spray tower body 101.

[0036] Specifically, the air inlet 102 is tangentially connected to the side wall of the spray tower body 101, that is, the edge of the air inlet 102 extends tangentially outward from the spray tower body 101, so that the exhaust gas enters the spray tower body 101 along the tangential path of the inner cavity.

[0037] Meanwhile, the tangential entry of exhaust gas is beneficial to the gas-liquid contact process in subsequent processes, mainly in three aspects. First, the tangential entry of exhaust gas into the spray tower body 101 creates a rotating and rising airflow within the inner cavity. This flow pattern helps to disperse the exhaust gas into fine bubbles, which is beneficial to increasing the contact area between the exhaust gas and the liquid in subsequent processes.

[0038] Secondly, the exhaust gas forms a rotating and rising airflow, which increases the relative motion amplitude between the exhaust gas and the liquid, thereby promoting mass transfer between the gas and liquid and improving absorption efficiency.

[0039] Thirdly, the centrifugal force generated during the upward rotation of the exhaust gas can separate the exhaust gas and liquid, which helps to throw the liquid droplets in the exhaust gas toward the inner wall of the spray tower body 101, thereby improving the gas-liquid separation effect.

[0040] In some examples, the jet assembly includes several hollow jet components 201. The exhaust gas first enters the inner cavity of the spray tower body 101 along the air inlet 102, and then enters the jet component 201. The inner cavity of the jet component 201 is used to contain the exhaust gas.

[0041] Furthermore, since a single jet component 201 cannot accommodate a large amount of waste gas, several jet components 201 are provided. Among them, each jet component 201 is arranged side by side inside the spray tower body 101, and is closely distributed.

[0042] It is worth noting that the total radial area of ​​the inner cavity of each jet component 201 is less than the radial area of ​​the inner cavity of the spray tower body 101. When the exhaust gas flows from the inner cavity of the spray tower body 101 to the inner cavity of each jet component 201, the flow space of the exhaust gas is reduced, which increases the flow rate of the exhaust gas and helps to ensure sufficient contact and reaction between the exhaust gas and the liquid in the subsequent process.

[0043] Specifically, the spray assembly includes several spray components 301, which are used to spray liquids with purifying capabilities. The number of spray components 301 is equal to the number of jet components 201, thus there is a one-to-one correspondence between the spray components 301 and the jet components 201. Simultaneously, the spray components 301 are disposed inside the jet components 201, allowing the liquid and exhaust gas to contact and react within the inner cavity of the jet components 201.

[0044] In some examples, such as Figure 1 As shown, a support member 202 is provided inside the spray tower body 101. The support member 202 extends radially in the inner cavity of the spray tower body 101 and is connected to the inner wall of the spray tower body 101. The support member 202 has a relatively fixed height in the spray tower body 101.

[0045] Furthermore, since each jet component 201 is disposed at the bottom of the support component 202, the plurality of jet components 201 in a single jet assembly have the same height. Therefore, each jet component 201 in a single jet assembly is radially distributed within the spray tower body 101. It is understood that each spray component 301 is also disposed on the support component 202.

[0046] Specifically, the ports of each jet component 201 used to receive exhaust gas are at the same height, and gaps are unavoidable between the ports of adjacent jet components 201. To prevent exhaust gas from passing through the jet assembly along the gaps between adjacent jet components 201, resulting in some exhaust gas not undergoing the gas-liquid contact purification process, a sealed area 203 is set between the ports of adjacent jet components 201.

[0047] In some examples, such as Figure 2 As shown, the jet component 201 is formed as a jet tube with two ports. One port is used to connect to the support component 202 and ensure that the spray component 301 is located in the inner cavity of the jet component 201; the other port is used to receive exhaust gas.

[0048] Furthermore, the jet component 201 includes a straight section 204 and an expansion section 205 connected to each other. The port of the straight section 204 is used to connect to the support component 202, and the port of the expansion section 205 is used to receive exhaust gas.

[0049] Specifically, the radial dimensions of the straight portion 204 are the same at all points, while the radial dimensions of the expansion portion 205 gradually increase in the direction away from the straight portion 204. It is understandable that a larger opening area is beneficial for the inflow of exhaust gas.

[0050] In some examples, the spray component 301 is located in the cavity defined by the straight section 204, and the exhaust gas and liquid come into contact and react within the cavity defined by the straight section 204.

[0051] The total radial area of ​​the inner cavity of each straight section 204 is 70% of the radial area of ​​the inner cavity of the spray tower body 101. This means that the waste gas flow space inside the jet component 201 is 30% smaller than the waste gas flow space inside the spray tower body 101, thus increasing the waste gas flow rate by approximately 30%. As the waste gas flow rate increases, the contact between the waste gas and the liquid becomes more efficient, and the reaction rate between the two is greater, thereby improving the spray mixing effect and achieving the goal of high-efficiency treatment.

[0052] In some examples, such as Figure 3 As shown, the spray assembly also includes a liquid channel, which includes a main channel 302 and several branch channels 303, and both the main channel 302 and the branch channels 303 are configured as straight lines.

[0053] The main channel 302 and the branch channel 303 are both used to connect the spray component 301 and to provide the spray component 301 with liquid for purification.

[0054] Specifically, the main channel 302 connects several spray components 301 along a single diameter of the spray tower body 101, while each branch channel 303 is connected to the main channel 302. Each branch channel 303 extends to the location of other spray components 301 and connects to the corresponding spray component 301. The liquid first flows along the main channel 302 and is gradually transferred to each branch channel 303, ensuring that all spray components 301 receive liquid delivery.

[0055] In addition, the spray tower body 101 is also equipped with a spray dosing tank 304, which is located at the bottom of the spray tower body 101. The spray dosing tank 304 is used to store the chemical solution and is connected to the main channel 302.

[0056] In some examples, a swirling component 401 is provided inside the spray tower body 101. The swirling component 401 is used to process the gas-liquid mixture of the outgoing jet assembly. The swirling component 401 is radially arranged in the inner cavity of the spray tower body 101, and the swirling component 401 is approximately parallel to the support component 202.

[0057] The swirl component 401 is spaced apart from the support component 202, and its height is greater than that of the support component 202. Since the height of the jet component and the spray component is less than that of the support component 202, the exhaust gas enters the spray tower body 101 through the air inlet 102 and flows from bottom to top. It first passes through the jet component 201 and the spray component 301 to form a gas-liquid mixture, and then passes through the swirl component 401 for treatment.

[0058] Specifically, the swirling component 401 intensifies the turbulence between the passing gas and liquid, achieving efficient contact and reaction. In terms of working principle, the swirling component 401 is mainly based on the action of centrifugal force. Through the rotation of the swirling component 401 and the action of gravity within the spray tower body 101, the gas and liquid are separated.

[0059] In some examples, such as Figure 4 As shown, the swirl component 401 includes a base and several swirl plates 402, with the base serving as the main support structure for mounting each swirl plate 402.

[0060] The substrate has an installation structure 403 in its center, and each swirl plate 402 is connected to the installation structure 403, forming a circumferential distribution and extending towards the edge of the substrate. It can be understood that after installation, the swirl plates 402 are inclined to the radial plane of the substrate, thereby achieving the swirling effect.

[0061] Specifically, 18 swirl plates 402 are provided. To ensure that the swirl plates 402 are evenly distributed, the included angle between adjacent swirl plates 402 is set to 20°, and the swirl plates 402 form an included angle of 23° with the radial plane of the substrate.

[0062] Furthermore, when the gas-liquid mixture passes through the swirling component 401, the rotation of the swirling plate 402 within the swirling component 401 disperses the gas and liquid into numerous small bubbles and droplets, thereby increasing the gas-liquid contact area and promoting gas-liquid separation. Since the liquid is denser than the gas, the droplets fall into the spray tower body 101, while the bubbles continue to rise and are eventually discharged from the outlet. Understandably, the design of the swirling plate 402 can affect the gas-liquid separation effect; for example, parameters such as the tilt angle and rotation speed of the swirling plate 402 need to be determined by the operators based on actual requirements.

[0063] In some examples, a single swirling component 401, a single supporting component 202, a single jet assembly, and a single spray assembly form a relatively complete purification unit. Depending on actual needs, the operator can select the specific number of purification units. It is understood that when the number of purification units is greater than one, the units are distributed vertically within the inner cavity of the spray tower body 101.

[0064] In some examples, a demisting component 501 is provided inside the spray tower body 101. The demisting component 501 is located near the air outlet 103 and is used to remove mist from the exhaust gas.

[0065] In some examples, the spray tower body 101 is provided with inspection ports 502. The number of inspection ports 502 is set according to actual needs. Staff can observe the waste gas purification process in the inner cavity of the spray tower body 101 through the inspection ports 502, which makes it easier to detect abnormalities in the purification process in a timely manner.

[0066] In actual implementation, the exhaust gas enters the inner cavity of the spray tower body 101 tangentially along the air inlet 102 and rotates and rises within the inner cavity. As it rises, the exhaust gas reaches the jet components 201, which have smaller flow spaces. Each spray component 301 sprays liquid within its respective jet component 201, allowing the exhaust gas to contact the liquid at a higher flow rate within a smaller space, thus improving gas-liquid contact and reaction efficiency and forming a gas-liquid mixture. The gas-liquid mixture continues to rise and undergoes gas-liquid separation at the swirl component 401, finally exiting the spray tower body 101 along the air outlet 103, completing the overall purification process.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
