Description
Technical Field
[0001] The utility model relates to the field of natural gas production, and particularly relates to a reagent calibration device. Background Art
[0002] During the production process of gas wells, the produced substances contain CO2 and SRB bacteria, which will corrode the wellbore string and surface process to varying degrees, resulting in leaks, perforations, and fractures in the equipment and pipelines in the process, and then causing the gas well to shut down, bringing high safety risks and economic losses.
[0003] At present, corrosion inhibitors and bactericides are injected by pumps for anti-corrosion, but the injection volume per hour cannot be accurately calibrated, resulting in insufficient or excessive injection of the reagent.
[0004] Therefore, at present, a technical solution is needed to solve the technical problem that it is difficult to control the injection volume of the reagent when adding the reagent to the pipeline through a dosing pump, resulting in excessive or insufficient reagent in the injection pipeline. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the technical problem that it is difficult to control the injection volume of the reagent when adding the reagent to the pipeline through a dosing pump, resulting in excessive or insufficient reagent in the injection pipeline, and provide a reagent calibration device.
[0006] The utility model provides a reagent calibration device, which includes a reagent tank, a two-position three-way valve, a calibration cup, a dosing pump, a calibration pipe, and a dosing pipe. The reagent tank, the calibration cup, the two-position three-way valve, and the dosing pump are sequentially connected through the calibration pipe. A first valve and a second valve are connected between the reagent tank and the calibration cup. The dosing pipe is connected between the first valve and the second valve. The reagent tank is connected to the two-position three-way valve through the dosing pipe.
[0007] When the reagent calibration device of the utility model is in use, the dosing pump is connected to the pipeline. Before dosing, the calibration process is first carried out. The first valve and the second valve are opened to allow the reagent to flow into the calibration cup. When the reagent in the calibration cup reaches a certain amount, the first valve and the second valve are closed. The calibration cup and the dosing pump are conducted through the two-position three-way valve. The dosing pump is started to inject the reagent in the calibration cup into the pipeline. After the injection is completed, the time used in the injection process is recorded, and the injection volume per unit time is calculated. Subsequently, the reagent dosing process is entered. The first valve is opened, and the reagent tank and the dosing pump are conducted through the two-position three-way valve. The dosing pump is started to pump the liquid medicine in the reagent tank into the pipeline. According to the injection volume per unit time calculated in the calibration process and the total amount of the reagent to be injected, the dosing time is controlled, so as to ensure that a sufficient amount of reagent is added to the pipeline, and at the same time, avoid waste or shortage caused by excessive liquid medicine.
[0008] Preferably, the calibration cup is a transparent material structural member.
[0009] The calibration cup is made of a transparent material, which facilitates observing the liquid level height in the calibration cup through the cup, thereby facilitating the control of the start and end times of calibration.
[0010] Preferably, scale lines are provided on the side wall of the calibration cup.
[0011] The scale lines can display the liquid level height in the calibration cup in real time, facilitating the staff to accurately control the amount of medicament injected.
[0012] Preferably, an overflow port is provided at the upper part of the calibration cup.
[0013] When the liquid level height in the calibration cup reaches the overflow port, the excess medicament will automatically drain through the overflow port, preventing over-injection of the medicament in the calibration cup and facilitating accurate control of the amount of medicament in the calibration cup.
[0014] Preferably, it further includes a liquid collection box, and the overflow port is communicated with the liquid collection box through a pipeline.
[0015] So that the liquid medicine flowing out of the overflow port can enter the liquid collection box through the pipeline, avoiding waste of the liquid medicine and environmental pollution around.
[0016] Preferably, the liquid collection box is communicated with the calibration cup through a pipeline, and a third valve is connected between the liquid collection box and the calibration cup.
[0017] After the calibration process is completed, the remaining liquid medicine in the calibration cup can be drained into the liquid collection box through the pipeline, avoiding waste of the medicament.
[0018] Preferably, it further includes a controller and a timer, and the timer, the first valve, the second valve, the third valve, the two-way three-way valve and the filling pump are respectively electrically connected to the controller.
[0019] During the medicament calibration process, the controller controls the first valve and the second valve to open, and the medicament flows to the calibration cup. After injecting a sufficient amount of medicament into the calibration cup, the controller controls the first valve and the second valve to close, makes the two-way three-way valve conduct the calibration cup and the filling pump, starts the filling pump to inject the medicament into the pipeline, and at the same time starts the timer to start timing. After a certain amount of medicament is discharged from the calibration cup, the two-way three-way valve and the timer are closed, and the injection amount of the medicament per unit time is calculated. Subsequently, the third valve is opened to discharge the remaining medicament into the medicament box for recycling; during the medicament filling process, the controller controls the first valve and the filling pump to open, and makes the two-way three-way valve conduct the medicament tank and the filling pump, and controls the injection time based on the injection amount of the medicament per unit time obtained in the previous process and the amount of medicament to be injected, thereby realizing the automatic control of the medicament calibration process and the filling process.
[0020] Preferably, it further includes a liquid level sensor which is arranged in the calibration cup and electrically connected to the controller.
[0021] The liquid level sensor can monitor the liquid level height in the calibration cup in real time and transmit an electrical signal to the controller. The controller can control the start and end of calibration according to the information given by the liquid level sensor, improving the automation degree of the calibration process.
[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] 2. In the calibration process of this application, the calibration cup can control the amount of medicine entering the pipeline during the calibration process, avoiding uncontrollable influence on the total amount of medicine injection during the calibration process.

[0038] During use, the filling pump 4 is connected to the pipeline. Before filling, a calibration process is first carried out. The first valve 7 and the second valve 8 are opened to allow the reagent to flow into the calibration cup 3. When the reagent in the calibration cup 3 reaches a certain amount, the first valve 7 and the second valve 8 are closed. The calibration cup 3 and the filling pump 4 are conducted through the two-way three-way valve 2. The filling pump 4 is started to inject the reagent in the calibration cup 3 into the pipeline. After the injection is completed, the time used in the injection process is recorded, and the injection amount per unit time is calculated. Subsequently, the reagent filling process is entered. The first valve 7 is opened, and the reagent tank 1 and the filling pump 4 are conducted through the two-way three-way valve 2. The filling pump 4 is started to pump the liquid medicine in the reagent tank 1 into the pipeline. According to the injection amount per unit time calculated during the calibration process and the total amount of reagent to be injected, the filling time is controlled, so as to ensure that a sufficient amount of reagent is added to the pipeline, and at the same time, avoid waste or shortage caused by excessive liquid medicine.
