Description

Technical Field

[0001] The present invention relates to the technical field of scale inhibitor production equipment, in particular to a quantitatively added scale inhibitor pH adjustment treatment device. Background Art

[0002] During the production of scale inhibitors, the pH value must be controlled within a certain range to achieve the desired effect. A high or low pH value will affect the production quality of the scale inhibitor. The traditional adjustment method is for the operator to continuously test the pH value of the scale inhibitor and then calculate the amount of acid or alkali to be used based on the volume of the scale inhibitor. This operation is complicated, the process is cumbersome, and it is time-consuming and labor-intensive.

[0003] The Chinese patent with patent number CN201821560646.5 discloses a "new type of pH adjustment equipment for the production of corrosion and scale inhibitors". The patent includes a pH regulator, a reagent transmission device, an acid and alkali solution transmission device, a water circulation heating device and a pH meter. When adjusting the pH value of the corrosion and scale inhibitor, an appropriate amount of corrosion and scale inhibitor is first introduced into the interior of the adjustment tank, and the pH value of the scale inhibitor is measured using a pH meter. According to the measured pH value, it is determined whether an appropriate amount of acidic solution or an appropriate amount of alkaline solution needs to be added. For example, if the pH value of the scale inhibitor measured by the pH meter is too high, an acidic solution is added, and the stirring paddle fully stirs the mixed solution of the acidic solution and the scale inhibitor. After the stirring is completed, the pH value of the scale inhibitor after stirring is measured using a pH meter. When the measured pH value is within the specified range, the required requirements are met and the pH value adjustment is completed.

[0004] However, the pH value of the scale inhibitor measured by the pH meter is mostly the local pH of the scale inhibitor storage tank. In fact, after the acid and alkaline solution is fully dissolved in the scale inhibitor storage tank, the pH adjustment of the scale inhibitor cannot meet the adjustment requirements.

[0030] The following is combined with Figure 1-2 The present invention is described in further detail.

[0031] Example 1

The device also comprises a pH meter 4, a three-way solenoid valve 5, a peristaltic pump 6 and a stirring component. The pH meter 4 adopts an existing product, which includes a pH meter 11. The pH meter 11 can monitor the pH adjustment degree of the scale inhibitor in the scale inhibitor storage tank 1 in real time and control the operation of the three-way solenoid valve 5, the peristaltic pump 6 and the stirring component. The pH meter 11 includes at least one group arranged at the bottom of the scale inhibitor storage tank 1, and multiple groups can also be set to collect pH values at multiple locations in the scale inhibitor storage tank 1 to determine the pH adjustment. The outlet pipes 9 of the alkaline solution storage tank 2 and the acidic solution storage tank 3 are connected to the inlet pipe 10 immersed in the scale inhibitor storage tank 1 through the three-way solenoid valve 5. By connecting the three-way solenoid valve 5, the passage of the three-way solenoid valve 5 can be automatically activated according to the need to add acidic solution or alkaline solution. If acidic solution needs to be added, the three-way solenoid valve 5 is controlled to pass the acidic solution in the acidic solution storage tank 3 into the scale inhibitor storage tank 1.

After the pH meter 4 first sets a threshold alarm, the pH meter 4 performs a secondary threshold measurement under delayed control to determine whether the three-way solenoid valve 5 and peristaltic pump 6 should perform a secondary action. The specific steps are:

[0034] After the pH meter 4 detects in real time that the pH value of the antiscalant storage tank 1 reaches a preset threshold value, after a period of working time of the stirring component, the pH meter 4 performs a secondary threshold value detection. When the second detection value is the preset threshold value, the three-way solenoid valve 5 and the peristaltic pump 6 do not operate. When the second detection value is lower than the preset threshold value, the pH meter 4 detects in real time the pH value of the antiscalant storage tank 1, controls and adjusts the three-way solenoid valve 5 and the peristaltic pump 6 to make the pH value reach the threshold value.

After comparing the actual measured pH value with the threshold value, the pH meter 4 controls the three-way solenoid valve 5 and the peristaltic pump 6 to work. The alkaline solution in the alkaline solution storage tank 2 or the acidic solution in the acidic solution storage tank 3 is transported to the antiscalant storage tank 1 to adjust the pH value of the antiscalant. When the pH meter 4 detects that the antiscalant is When the pH value in the liquid storage tank 1 reaches the threshold value, the time delay controller is used to ensure that power is continuously supplied. During this time, the stirring component mixes and stirs the liquid in the antiscalant liquid storage tank 1, and the pH meter 4 detects the pH value in the antiscalant liquid storage tank 1 in real time for the second time. When the second detection value reaches the preset threshold value, the three-way solenoid valve 5 and the peristaltic pump 6 do not operate. When the second detection value is lower than the preset threshold value, the pH value of the antiscalant liquid storage tank 1 is detected in real time by the pH meter 4, and the three-way solenoid valve 5 and the peristaltic pump 6 are controlled and adjusted to operate so that the pH value reaches the threshold value.
