Description

Technical Field

[0001] This application relates to the technical field of chlorine absorption, and particularly to a chlorine absorption device. Background Technology

[0002] In industrial manufacturing processes, chlorine is a corrosive and highly toxic chemical substance. If released directly into the atmosphere without treatment, it will cause serious damage and pollution to the environment. Therefore, to ensure both environmental protection and safety in industrial production, chlorine absorption devices must be used to absorb and purify it.

[0003] In the existing technology, during the treatment of chlorine gas, the leaked liquid chlorine gas cylinder is usually put into a pool containing lime water, so that the leaked chlorine gas is absorbed by the lime water in the pool and undergoes a neutralization reaction. However, in the existing technology, when liquid chlorine cylinders are put into the pool, some of the leaking liquid chlorine cylinders will float on the water surface. As a result, the leaked chlorine cannot react with lime water and therefore cannot be absorbed and neutralized. Utility Model Content

[0004] This utility model provides a chlorine absorption device that can effectively absorb and neutralize chlorine gas leaking from a liquid chlorine cylinder floating on the water surface.

[0005] To achieve the aforementioned objectives, this application adopts the following technical solution: A chlorine absorption device, comprising The chlorine absorption mechanism has a gas recovery mechanism connected to its top, a first absorbent pool and a second absorbent pool connected to its middle section, and an absorbent purification pool connected to its bottom. The absorbent purification pool is connected to the second absorbent pool. In the middle section of the chlorine absorption mechanism, a first chlorine absorption mechanism and a second chlorine absorption mechanism are respectively provided. The first chlorine absorption mechanism is located above the second chlorine absorption mechanism. The first chlorine absorption mechanism includes a slowing layer and a chlorine absorption layer disposed between the slowing layer. The second chlorine absorption mechanism includes a heating component and a high-pressure spray component. The top of the second chlorine absorption mechanism is also provided with a local turbulence device to slow down the time it takes for chlorine to flow from the second chlorine absorption mechanism to the first chlorine absorption mechanism, thereby increasing the reaction time of chlorine in the second chlorine absorption mechanism.

[0006] In some alternative embodiments, the chlorine absorption mechanism is provided with a first extraction mechanism at the top, which is connected to the gas recovery mechanism.

[0007] In some optional embodiments, the mitigation layer includes an upper mitigation layer and a lower mitigation layer, with a chlorine-absorbing layer provided between the upper and lower mitigation layers. The chlorine-absorbing layer is a chlorine-absorbing bead or chlorine-absorbing ball, which mainly serves as a secondary auxiliary absorption layer.

[0008] In some alternative embodiments, the heating component is disposed on the inner sidewall of the chlorine absorption mechanism.

[0009] In some optional embodiments, a high-pressure atomizing component is further provided on the inner wall of the chlorine absorption mechanism. The high-pressure atomizing component is connected to the second absorption liquid pool, and the chlorine absorption mechanism forms a reaction space corresponding to the second chlorine absorption mechanism.

[0010] In some alternative embodiments, a second suction mechanism is provided at the top of the first absorbent pool.

[0011] In some alternative embodiments, a dual-head chlorine gas detection assembly is also provided at the top of the first absorption liquid tank.

[0012] In some optional embodiments, the bottom of the absorbent purification tank is provided with a stirring paddle, and the side wall of the absorbent purification tank is also provided with an absorbent purification powder box.

[0013] In some optional embodiments, the absorbent purification powder box has several openings on its side wall and a box cover on its top.

[0014] The chlorine absorption device provided in this application has the following beneficial effects: In the technical solution adopted in this application, a chlorine absorption device detects chlorine floating in the upper part of the first absorption liquid tank using a dual-head chlorine detection component. When unabsorbed chlorine is detected in the first absorption liquid tank, an external control switch activates the chlorine absorption mechanism to perform a secondary absorption of the leaked chlorine that was not initially absorbed. A first extraction mechanism draws the unabsorbed chlorine from the first absorption liquid tank into the chlorine absorption mechanism. After passing through the second chlorine absorption mechanism, a high-pressure spray component sprays the absorbent liquid in the second absorption liquid tank, where it reacts with the chlorine. The reaction process is heated by a heating component, and then passed through the first absorption mechanism... The chlorine absorption mechanism uses upper and lower deceleration layers to slow the flow rate of chlorine gas from the second chlorine absorption mechanism to the chlorine absorption layer, increasing the residence time in the chlorine absorption layer and improving the reaction and absorption time of the chlorine gas in the chlorine absorption layer. Finally, after passing through the first chlorine absorption mechanism, the chlorine gas is fully absorbed, and the remaining gas is extracted by the first gas extraction mechanism and enters the gas recovery mechanism. In addition, the absorbent liquid after spraying is purified by the absorbent liquid purification tank and then enters the second absorbent liquid tank. At the same time, under the action of the local turbulence device, the chlorine gas leaking from the liquid chlorine cylinder floating on the water surface can be effectively absorbed and neutralized.

Figure 3 This is a structural diagram of a local turbulence device in a chlorine absorption apparatus according to this application. Figure 1 , Figure 2 and Figure 3 As shown, the top of the chlorine absorption mechanism 10 is provided with a first suction mechanism 11, which is connected to the gas recovery mechanism 35. The first suction mechanism 11 guides and increases the flow velocity of the remaining gas after chlorine absorption, thereby recovering the remaining gas to the gas recovery mechanism 35. In the middle of the 35, a first chlorine absorption mechanism 12 and a second chlorine absorption mechanism 13 are respectively provided. The first chlorine absorption mechanism 12 is located above the second chlorine absorption mechanism 13. The first chlorine absorption mechanism 12 includes a slowing layer 14 and a chlorine absorption layer 15 disposed between the slowing layers 14. The slowing layer 14 includes an upper slowing layer 141 and a lower slowing layer 142. The chlorine absorption layer 15 is disposed between the upper slowing layer 141 and the lower slowing layer 142.

Figure 4 This is an internal structural diagram of the top of the first absorbent pool in a chlorine absorption device according to this application, viewed from another angle. Figure 5 This is an internal structural diagram of the absorbent purification tank in a chlorine absorption device according to this application. Figure 6 This is a perspective view of the absorption liquid purification tank in a chlorine absorption device according to this application. Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the top of the first absorption liquid tank 20 is equipped with a second suction mechanism 21. The first absorption liquid tank 20 is a reaction tank for preliminary treatment of leaked liquid chlorine gas cylinders. The second suction mechanism 21 extracts the leaked chlorine gas from the liquid chlorine gas cylinder floating on the water surface into the chlorine absorption mechanism 10. In addition, the top of the first absorption liquid tank 20 is also equipped with a double-headed chlorine gas detection component 22. The double-headed chlorine gas detection component 22 detects the chlorine gas floating in the upper part of the first absorption liquid tank 20. When unabsorbed chlorine gas is detected in the first absorption liquid tank 20, the chlorine absorption mechanism 10 is activated by an external control switch to perform secondary absorption of the leaked chlorine gas that was not absorbed in the first absorption. The bottom of the absorption liquid purification tank 30 is equipped with a stirring paddle 31, which includes, but is not limited to, a fork-shaped frame or a single rod-shaped frame, as long as it can stir the quantitatively collected absorption liquid and make it rotate. In addition, the side wall of the absorption liquid purification tank 30 is also equipped with an absorption liquid purification powder box 32. The side wall of the powder box is provided with several openings 34, and the top of the box is provided with a cover 33. By placing the absorption liquid purification powder in the absorption liquid purification powder box 32, the rotating absorption liquid carries the purification powder inside the powder box into the absorption liquid multiple times as it passes through the absorption liquid purification powder box 32. With the rotation of the absorption liquid, the purification powder reacts fully with the purification powder, thereby achieving the purification of the absorption liquid that has completed the secondary chlorine absorption. This effectively avoids the situation of uneven dissolution and incomplete reaction caused by directly adding the purification powder.

[0025] Here, the dual-head chlorine detection component 22 detects the chlorine floating in the upper part of the first absorption liquid tank 20. When unabsorbed chlorine is detected in the first absorption liquid tank 20, the chlorine absorption mechanism 10 is activated by an external control switch to perform a secondary absorption of the leaked chlorine that was not absorbed initially. The first extraction mechanism 11 extracts the unabsorbed chlorine from the first absorption liquid tank 20 into the chlorine absorption mechanism 10. After passing through the second chlorine absorption mechanism 13, the high-pressure spray component 17 sprays the absorbent liquid in the second absorption liquid tank 23. The absorbent liquid reacts with the chlorine, and the reaction process is heated by the heating component 16. At the same time, the flow is turbulent by a local turbulence device. After passing through the first chlorine absorption mechanism 12, the upper and lower deceleration layers 142 slow down the flow rate of the chlorine after absorption by the second chlorine absorption mechanism 13 towards the chlorine absorption layer 15, increasing the retention time in the chlorine absorption layer 15 and improving the efficiency of the chlorine absorption layer 15. 5. The reaction and absorption time of chlorine gas; Finally, after passing through the first chlorine absorption mechanism 12, the chlorine gas is fully absorbed, and the remaining gas is extracted by the first extraction mechanism 11 and enters the gas recovery mechanism 35; In addition, the absorbent liquid after spraying is purified by the absorbent liquid purification tank 30 and then enters the second absorbent liquid tank 23, realizing the effective absorption and neutralization of chlorine gas leaked from the liquid chlorine cylinder floating on the water surface; It should be noted that a gas cylinder inlet 24 is provided at the upper part of the side wall of the first absorbent liquid tank 20, so as to put the leaking gas cylinder into the first absorbent liquid tank 20. A sealing door 25 is connected to the gas cylinder inlet 24 to form a closed space inside the first absorbent liquid tank 20, preventing the gas leaked from the gas cylinder from being released into the air. The connection between the sealing door 25 and the gas cylinder inlet 24 includes, but is not limited to, a hinged or sliding connection.
