Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and in particular to an alkaline neutralization tank. Background Technology

[0002] In natural gas purification and treatment plants, alkaline neutralization tanks are containers mainly used for neutralizing acidic wastewater. By adding alkaline solution to the tank containing acidic wastewater, the acidic wastewater is rendered harmless.

[0003] Existing alkaline neutralization tanks typically use separate pipes to continuously feed wastewater and neutralizing agents. A metering device on the pipes ensures quantitative matching of wastewater and agents. However, in practice, it has been found that due to the significant volume difference between wastewater and agent dosage, the inlets for these pipes are usually located only at the top of the tank or near the top side wall. Neutralized wastewater exits from the bottom of the tank or near the bottom side wall. This results in uneven mixing of wastewater and agents within the tank, leading to pH differences in the mixed liquid along different heights. Furthermore, the lack of level monitoring devices prevents the detection of dynamic changes in the wastewater during treatment, easily resulting in over- or under-neutralization, wasting raw materials, adversely affecting subsequent processes, and even causing the treated wastewater to fail to meet standards. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing alkali neutralization tanks, which result in uneven mixing and substandard wastewater after treatment, and to provide an alkali neutralization tank.

[0005] This utility model provides an alkali neutralization tank, comprising: a tank body, which is a vertical storage tank; a liquid addition pipe extending vertically into the tank body, wherein the liquid addition pipe has a spiral channel and a plurality of through holes penetrating the spiral channel; and a chemical addition pipe communicating with the spiral channel, wherein the chemical addition pipe is connected to a chemical supply mechanism.

[0006] This utility model discloses an alkaline neutralization tank. A liquid addition pipe is used to input wastewater into the tank, and a chemical addition pipe is used to input chemicals. By connecting the chemical addition pipe and the liquid addition pipe, the wastewater and chemicals are mixed in the liquid addition pipe before entering the tank. This pre-mixing of wastewater and chemicals during transportation and simultaneous input into the tank ensures more uniform mixing upon entry. Furthermore, the spiral channel within the liquid addition pipe extends the mixing path of the wastewater and chemicals, ensuring thorough mixing and improving wastewater treatment efficiency.

[0007] Preferably, a premixing chamber is connected to the top of the liquid addition pipe, the premixing chamber is nested with the top of the tank, and the dosing pipe is connected to the premixing chamber. This allows the wastewater and the reagent to be initially mixed in the premixing chamber.

[0008] Preferably, the liquid inlet pipe is connected to a drive mechanism, which drives the liquid inlet pipe to rotate. The drive mechanism is located at the top of the tank. This rotation of the liquid inlet pipe causes the liquid inside the tank to flow, further improving the treatment effect.

[0009] Preferably, the drive mechanism includes a first gear and a second gear, with the first gear fitted into the premixing chamber or the liquid addition pipe.

[0010] Preferably, the tank body is provided with a partition, which divides the interior of the tank body into a first chamber and a second chamber arranged vertically. The liquid addition pipe passes through the partition, the first chamber is connected to a drain pipe, and the through hole is provided on the liquid addition pipe located in the second chamber. This allows the wastewater and reagent to be fully mixed in the second chamber before being discharged through the first chamber, extending the mixing time and path of the liquid in the tank body, and allowing for overflow discharge.

[0011] Preferably, the partition has a central channel and several liquid passage holes, and the liquid inlet pipe passes through the central channel. This allows the liquid in the second chamber to smoothly enter the first chamber for output.

[0012] Preferably, the tank is equipped with a level gauge and a pH detection mechanism. The pH detection mechanism is connected to the first chamber or the drain pipe, and the level gauge is connected to the first chamber. This enables real-time monitoring of the pH value and level of the liquid inside the tank.

[0013] Preferably, the first chamber is connected to a clean water supply mechanism.

[0014] Preferably, the liquid addition pipe includes a straight section and a curved section, the straight section passing through the baffle, and the spiral channel disposed in the curved section. This allows the liquid in the tank to be stirred through the curved section, resulting in a more uniform mixture.

[0015] Preferably, the second chamber has a conical liquid cavity at its bottom, and an output pipe is provided at the bottom of the conical liquid cavity. The output pipe is equipped with a valve switch. This allows the liquid in the tank to be completely discharged as needed.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides an alkaline neutralization tank. By connecting the dosing pipe and the liquid dosing pipe, the wastewater and the reagent are mixed in the liquid dosing pipe before entering the tank. This allows the wastewater and the reagent to be pre-mixed during transportation and simultaneously input into the tank, resulting in more uniform mixing after entering the tank. 2. This utility model provides an alkaline neutralization tank, which extends the mixing path of wastewater and reagents through a spiral channel set in the liquid addition pipe, ensuring that wastewater and reagents are fully mixed and improving the wastewater treatment effect.

[0026] Example like Figures 1-2 As shown, an alkaline neutralization tank includes a tank body 1, a liquid addition pipe 2, and a chemical addition pipe 3. The tank body 1 is a vertical storage tank. The liquid addition pipe 2 extends vertically into the tank body 1 and has a spiral channel inside. The liquid addition pipe 2 has several through holes 21 that penetrate the spiral channel. The chemical addition pipe 3 is connected to the spiral channel and is connected to a chemical supply mechanism.

[0027] In optional implementations, such as Figure 1 As shown, the liquid addition pipe 2 and the chemical addition pipe 3 can converge near the top of the tank 1, so that wastewater and chemicals are transported along the spiral channel of the liquid addition pipe 2 and output into the tank 1 from the through hole 21 set in the liquid addition pipe 2.

[0028] In one or more embodiments, the top of the liquid addition pipe 2 is connected to a premixing chamber 4, which is nested with the top of the tank body 1. The dosing pipe 3 is connected to the premixing chamber 4. The wastewater and the reagent are initially mixed in the premixing chamber 4, and then transported along the spiral channel of the liquid addition pipe 2, and output into the tank body 1 from the through hole 21 of the liquid addition pipe 2.

[0029] In optional implementations, such as Figure 2 As shown, the premixing chamber 4 can be a circular tube structure with a larger internal cross-section than the liquid addition pipe 2. The premixing chamber 4 extends out of the top of the tank body 1. Conventional wastewater pipes and dosing pipes 3 can be connected to the top of the premixing chamber 4, so that wastewater and chemicals enter the premixing chamber 4 from top to bottom for mixing, and are then transported into the tank body 1 along the liquid addition pipe 2.

[0030] In an optional embodiment, the liquid filling tube 2 can be made into a spiral tube to form a spiral channel inside the liquid filling tube 2.

[0031] In one or more embodiments, the liquid inlet pipe 2 is connected to a drive mechanism 5, which drives the liquid inlet pipe 2 to rotate. The drive mechanism 5 is located on the top of the tank body 1. When the liquid inlet pipe 2 rotates, it causes the liquid inside the tank body 1 to flow, further improving the treatment effect.

[0032] In an optional embodiment, the drive mechanism 5 may include a first gear 51, a second gear 52 and a drive motor. The drive mechanism 5 drives the gears to rotate and transmit, thereby realizing the rotation drive of the liquid filling pipe 2.

[0033] In optional implementations, such as Figure 1 As shown, the first gear 51 can be fitted onto the liquid filling pipe 2, and the second gear 52 meshes with the first gear 51 and is driven to rotate by a drive motor.

[0034] In optional implementations, such as Figure 2 As shown, the first gear 51 can also be fitted into the premixing chamber 4.

[0035] In optional implementations, such as Figure 1 , Figure 2 As shown, the drive mechanism 5 can be mounted on a bracket on the top of the tank 1 to ensure the installation stability of the drive mechanism 5.

[0036] In one or more embodiments, a partition 6 may be provided inside the tank 1, dividing the interior of the tank 1 into a first chamber 11 and a second chamber 12 arranged vertically. A liquid inlet pipe 2 passes through the partition 6, and a drain pipe 13 is connected to the first chamber 11. A through hole 21 is provided on the liquid inlet pipe 2 located in the second chamber 12. After the wastewater and reagent enter the second chamber 12 along the liquid inlet pipe 2, they are fully mixed in the second chamber 12, and then pass through the partition 6 into the upper first chamber 11, and are discharged from the drain pipe 13 of the first chamber 11. This prolongs the mixing time and path of the liquid in the tank 1, and realizes the output of the treated liquid in an overflow manner.

[0037] In an optional embodiment, the partition 6 may be provided with a central channel 61 and a plurality of liquid passage holes 62, through which the liquid filling pipe 2 passes. This allows the liquid in the second chamber 12 to smoothly enter the first chamber 11 for output.

[0038] In an optional embodiment, the central channel 61 can be larger than the liquid filling pipe 2, so that there is a gap between the outer wall of the liquid filling pipe 2 and the central channel 61, so that the first chamber 11 and the second chamber 12 are always in communication, avoiding the impact on the processing effect due to blockage of the liquid passage 62 or other reasons.

[0039] In an optional embodiment, the liquid addition pipe 2 may include a straight pipe section 22 and a curved pipe section 23. The straight pipe section 22 passes through the partition 6, and the spiral channel is provided in the curved pipe section 23. This allows the liquid in the tank 1 to be stirred through the curved pipe section 23, resulting in a more uniform mixture.

[0040] In one or more embodiments, the tank 1 is equipped with a level gauge 7 and a pH detection mechanism. The pH detection mechanism is connected to the first chamber 11 or the drain pipe 13, and the level gauge 7 is connected to the first chamber 11. This enables real-time monitoring of the pH value and level of the liquid inside the tank 1.

[0041] In one or more embodiments, the first chamber 11 is connected to the clean water supply mechanism 9.

[0042] In an optional embodiment, the clean water supply mechanism 9 can be a clean water pipe that extends into the first chamber 11. When the pH value of the treated liquid exceeds the requirements, it can be further diluted by adding clean water to ensure a better treatment effect.

[0043] In an optional embodiment, the pH testing mechanism can be set in the first chamber 11 and the second chamber 12 respectively, and the result can be displayed in real time on the tank body 1 to ensure that the staff can obtain the processing results in real time.

[0044] In one or more embodiments, the bottom of the second chamber 12 is provided with a conical liquid chamber 14, the bottom of the conical liquid chamber 14 is provided with an output pipe 15, and the output pipe 15 is provided with a valve switch 16. This allows the liquid in the tank 1 to be completely discharged according to the actual situation.

[0045] This embodiment of an alkaline neutralization tank includes a liquid addition pipe 2 for introducing wastewater into a tank 1 and a chemical addition pipe 3 for introducing chemicals. By connecting the chemical addition pipe 3 to the liquid addition pipe 2, the wastewater and chemicals are mixed in the liquid addition pipe 2 before entering the tank 1. This allows the wastewater and chemicals to be pre-mixed during transport and simultaneously introduced into the tank 1, resulting in more uniform mixing upon entering the tank 1. Furthermore, the spiral channel within the liquid addition pipe 2 extends the mixing path of the wastewater and chemicals, ensuring thorough mixing and improving wastewater treatment efficiency. Additionally, the partition plate 6 within the tank 1 further extends the mixing path of the liquid within the tank 1, further enhancing the treatment effect.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
