Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to an acid-base neutralization device. Background Technology

[0002] Enterprises generate acidic or alkaline wastewater during production, which must be neutralized before discharge. Typically, a neutralization container is used to collect the wastewater, and acid or alkali is added to neutralize it. The pH value in the neutralization container is monitored in real time, and the wastewater is only discharged when the pH meets requirements. Current technology uses sensors in the neutralization container to continuously monitor the pH value of the wastewater, adding acid or alkali as needed until it meets wastewater discharge standards. However, the sensors in this technology are constantly immersed in the wastewater, and because the wastewater in the neutralization container is at a high temperature for extended periods, the sensors have a short lifespan. Once the sensors fail, the discharged wastewater will not meet the required pH level, causing water pollution.

[0003] Therefore, there is an urgent need for an acid-base neutralization device to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an acid-base neutralization device to solve the problem of easy damage to detection sensors in the prior art.

[0005] To achieve the above objectives, this utility model provides an acid-base neutralization device, including a neutralization container and a detection sensor. The neutralization container is provided with a waste liquid inlet, a waste liquid outlet, and an acid / base liquid inlet. The neutralization container is also equipped with a stirrer. The acid-base neutralization device further includes a detection pool and a sampling channel. The neutralization container is provided with a sampling outlet. The two ends of the sampling channel are respectively connected to the sampling outlet and the inlet of the detection pool. The detection sensor is located in the detection pool. The sampling channel is provided with a detection valve. When the detection valve is opened, the waste liquid in the neutralization container flows from the sampling channel to the detection pool.

[0006] Preferably, the acid-base neutralization device further includes a cleaning component, which includes a cleaning liquid source, a cleaning pipe, and a cleaning valve. The cleaning liquid source is connected to the detection tank through the cleaning pipe, and the cleaning valve is located in the cleaning pipe for washing the detection sensor.

[0007] Preferably, the waste liquid inlet is connected to an inlet pipe, the waste liquid outlet is connected to a drain pipe, and the acid / alkali liquid inlet is connected to an acid / alkali liquid pipe.

[0008] Preferably, the inlet pipe is equipped with an inlet valve, the outlet pipe is equipped with an outlet valve, and the acid / alkali pipe is equipped with an acid / alkali valve.

[0009] Preferably, the neutralization container is a neutralization tank.

[0010] Preferably, the cleaning solution source is tap water.

[0011] Preferably, the sampling channel is a sampling tube.

[0012] Preferably, the acid-base neutralization device further includes a reflux pump, and the neutralization container is provided with a reflux port. The reflux pump is connected to the outlet of the detection pool and the reflux port respectively through a reflux pipe, for pumping the liquid from the detection pool back to the neutralization container.

[0013] As can be seen from the above, the technical solution provided by this utility model sets up a detection pool and a sampling channel, and places the detection sensor in the detection pool. When detection is required, a small portion of the waste liquid in the detection container is discharged into the detection pool for detection. The detection sensor does not need to be immersed in the waste liquid in the high-temperature neutralization container for a long time, which extends the life of the detection sensor and ensures that the discharged waste liquid meets environmental protection requirements.

[0032] Example 1

[0033] like Figure 1 As shown in the figure, this embodiment provides an acid-base neutralization device, including a neutralization container 10, a detection sensor 20, a sampling channel 30, and a detection pool 40.

[0034] The neutralization container 10 is provided with a waste liquid inlet 11, a waste liquid outlet 12, and an acid / alkali inlet 13. The waste liquid inlet 11 is connected to an inlet pipe 50, which is equipped with an inlet valve 51. The waste liquid outlet 12 is connected to a drain pipe 60, which is equipped with a drain valve 61. The acid / alkali inlet 13 is connected to an acid / alkali pipe 70. In this embodiment, the acid / alkali inlet 13 includes an acid inlet 131 and an alkali inlet 132. The acid / alkali pipe 70 includes an acid pipe 71 and an alkali pipe 72. The acid pipe 71 is connected to the acid inlet 131, and the alkali pipe 72 is connected to the alkali inlet 132. The acid / alkali pipe 70 is equipped with acid / alkali valves. In this embodiment, the acid / alkali valves include an acid valve 73 and an alkali valve 74. The acid valve 73 is located on the acid pipe 71, and the alkali valve 74 is located on the alkali pipe 72.

[0035] The neutralization container 10 is also equipped with a sampling outlet 14. The two ends of the sampling channel 30 are connected to the sampling outlet 14 and the inlet of the detection pool 40, respectively. A detection sensor 20 is located in the detection pool 40, and a detection valve 31 is provided in the sampling channel 30. When the detection valve 31 is opened, the waste liquid in the neutralization container 10 flows from the sampling channel 30 to the detection pool 40, and the detection sensor 20 detects the pH of the waste liquid. The detection pool 40 has a very small volume, and its pH is detected by acquiring a small amount of waste liquid. In other embodiments, a space can be provided in the sampling channel 30 as the detection pool 40.

[0036] The neutralization container 10 is equipped with a stirrer 16, which ensures that the acid and / or alkali solution is fully mixed with the waste liquid in the neutralization container 10.

[0037] In use, waste liquid enters neutralization container 10 through inlet pipe 50 from waste liquid inlet 11. After receiving a certain amount, stirrer 16 is started. After the waste liquid is stirred evenly, detection valve 31 is opened, and waste liquid flows from sampling outlet 14 through sampling channel 30 to detection pool 40. Detection sensor 20 measures the pH value of waste liquid in detection pool 40, and detection valve 31 is closed. The amount of acid or alkali to be added is calculated based on the pH value detected by detection sensor 20, and an appropriate amount of acid or alkali is added. After the waste liquid is stirred evenly, detection valve 31 is opened again, and the pH value of waste liquid in neutralization container 10 is detected again. If the pH value of waste liquid does not meet the requirements, acid or alkali is added again. When the pH value of waste liquid in neutralization container 10 is detected to meet the discharge pH requirements, drain valve 61 is opened, allowing waste liquid in neutralization container 10 to be discharged from waste liquid outlet 12 and drain pipe 60. The acid-base neutralization device of this invention is equipped with a detection pool and a sampling channel. The detection sensor is placed in the detection pool. When detection is required, a small portion of the waste liquid in the detection container is discharged into the detection pool for detection. The detection sensor does not need to be continuously immersed in the high-temperature waste liquid in the neutralization container, thus extending the life of the detection sensor and ensuring that the discharged waste liquid meets environmental protection requirements.

[0038] In this embodiment, the sampling channel 30 is a sampling tube, and the two ends of the sampling tube are connected to the sampling outlet 14 and the inlet of the detection pool 40, respectively.

[0039] Furthermore, the acid-base neutralization equipment also includes a cleaning assembly, which comprises a cleaning solution source 81, a cleaning pipe 82, and a cleaning valve 83. The cleaning solution source 81 is connected to the detection tank 40 via the cleaning pipe 82, and the cleaning valve 83 is located on the cleaning pipe 82 for washing the detection sensor 20. During use, after the detection valve 31 is closed, the cleaning valve 83 is opened, and the detection sensor 20 is washed with the cleaning solution provided by the cleaning solution source 81, further extending the life of the detection sensor 20. The cleaning solution source 81 is preferably tap water.

[0040] Preferably, the neutralization container 10 is a neutralization tank, which is made of stainless steel and has an acid and alkali corrosion resistant coating on its inner wall.

[0041] In this embodiment, the outlet of the detection pool 40 and the drain pipe 60 are connected together.

[0042] Example 2

[0043] like Figure 2 As shown, this embodiment is basically the same as embodiment 1, except that in this embodiment, the detection pool 40 is embedded in the side wall of the neutralization container 10, and the sampling channel 30 is a through hole. As shown in the figure, in this embodiment, the sampling channel 30 coincides with the sampling outlet 14. In other embodiments, a space can also be provided in the neutralization container 10 as the detection pool 40, that is, the detection pool is built into the neutralization container 10, and a sampling channel and a sampling valve are provided.

[0044] Example 3

[0045] like Figure 3 As shown, this embodiment is basically the same as Embodiment 1 or Embodiment 2, except that in this embodiment, the acid-base neutralization device also includes a reflux pump 90, and the neutralization container 10 is provided with a reflux port 15. The reflux pump 90 is connected to the outlet of the detection tank 40 and the reflux port 15 respectively through a reflux pipe 91, for pumping the liquid in the detection tank 40 back to the neutralization container 10. In Embodiment 1, during the detection process, a small amount of waste liquid flows out through the outlet of the detection tank 40 and is eventually discharged into the environment through the drain pipe 60. Although the amount of this liquid is small, it can still have an impact on the environment if accumulated. In this embodiment, a reflux pump 90 and a reflux pipe 91 are set at the outlet of the detection tank 40 to pump the waste liquid used for detection back to the neutralization container 10, achieving zero discharge of waste liquid used for detection.

[0046] Example 4

[0047] like Figure 4As shown, this embodiment is basically the same as Embodiment 1, except that in this embodiment, there is only one acid / alkali inlet 13, and the acid / alkali pipe 70 includes an acid pipe 71 and an alkali pipe 72. The acid / alkali inlet 13 is connected to the acid pipe 71 and the alkali pipe 72 respectively through a tee connector. The acid / alkali valves include an acid valve 73 and an alkali valve 74. The acid valve 73 is located on the acid pipe 71, and the alkali valve 74 is located on the alkali pipe 72.

[0048] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
